I am looking at getting a set of new rims for my car, and I want to go pretty big....20's Nitto has made a new low pro tire for sports cars called the NT555. Its "designed specifically to fit your sports sedan, taking your game to the next level." The nummbers are 225/35/zr20...would this fit on a 3rd gen? I dont know much about tires or rims, and i have no clue what those numbers mean. If someone has done it or has pics or can tell me why it cant be done id apriciate it. Thanx!

 

225.....

Those are some damn skinny tires for 20" wheels

Yes they will fit a thirdgen, you need to modify the fender wells (ie....remove plastic, remove fender lip...)

Having a drop and 20's will require extensive modifications....

 

If it can be done I'll getter done. they are some seriously low-profile tires. I would like to throw a 1"drop on there as well, but if I can't I wont be to worried about it....cuz ill have 20's

 

I say go for it

And just to show you what they look like........

 

is that your car? I didnt think it looked like that! if it is, where did you get the rims from?

 

Not my car,

My car with 19" (ok, so they aren't 20's ) wheels on it, is in my sig

The wheels are KMC Stealths

I would strongly advise first buying the 20" wheels, putting them on the car, and then lowering it as needed and making modifications to the wheel well when you see potential problems....

I made the mistake of lowering, then adding large wheels....

 

Thanx for the info, I'll be sure to do that

 

If you do it atleast get tastefull rims. Two things
1. hope you have super smooth streets
2. hope you got one hell of a bank account cause nittos are big $$$

 

you can pick up 20" tires as cheap as 18's these day. I have 20's on my mustang. was going to switch to 18's because I needed new tires and too my suprise 20 inch tires have some down a ton.

you can gett 255/35r20 goodyears off tirerack for lile $180 a tire. the tires size goes as follows

here is a laymens term intro into tire size. it is a bit more complex but this will give you the idea

225 is the width. this number should be matched to your wheel width to get the proper footprint to the road. ie 245 on a 8" rim 275 on a 9" etc. you can fudge this a bit but you get the point.

35 is the series has to do with the sidwall. the lower the number the smaller the sidwall

then the other is the wheel size.

a 245/50-16 for example is 25.6"

a 225/35-20 is 26.2"

so it is not much bigger probaly fit easy

a 245/40-20 is 27.7 starting to get big

use this link to compare tire sizes might help you out.

Just pick you wheels wisely. my wheels on my mustang are a love hate relationship. sometimes I think they are a bit new school. Other people usually like them though. I like the fact I am down 2" and have no fender gap. I can also still get a jack under my car.

 

What's the stock tire diameter?

My wheels came out to 27" even....

 

I think stock is proably the 25.6. not 100% positive though

my stang was 25.6 stock and now I am at 27.7 but I rub just a hair so I am coming down to 27 next tire buy.

 

guys, you've helped me a ton, now to find the right rims....any sites that can be helpful on the rim purchase?

 

my .02 is to find the offset/backspacing and width that the stock wheel is and then search manufactures sites for wheels with that offset. when plus sizing wheels offset is critical. read up on how to calculate offset and backspace

basically offset w/2+b=o

width/2 - backpasing = ofset that way if a site only lists one or the other you can convert


for example

8 inch rim with 4 inch backspace has 0 offset 8 inch rim with 5 inch bachspace has a positive backspace.

on my mustang I had a hard time finding 20" rims in the right backspace that where not custom rims that cost $500 a piece. now if you can afford that I would just go to budik or boyd wheels and order a custom set. if you are on a budget check out like eagle or something. they have some 20's for like $250 a wheel I just could not find anyone that stocked them for my car. they all had 0 ofset and I needed +24mm.

wheels are all personal taste though. I am thinking about just putting 20" iroc replicas on mine. they look pretty trick.

these are what I was looking at originally for my mustang. they were cheap and I though they looked clean.

 

go to ebay and buy 20" iroc rims

 

personally i wouldnt go as high as 20" rims because the bigger tbhe rim is the more it raises your car off the ground because the axel is moved up due to the larger rim,which makes it harder to get that mean/low stance personally i would go with something like a 17 or a 18 inch rim with a 1"-2" drop

anyways ive done my ranting on my opinion but like many have said before to each his own.

 

Well it definitely can be done because that is my car with the flames that FlyNLow posted the pic of. I have plenty of room as a matter of fact I am about to lower it about 1in. Also thinkin about getting some different rims. I am lookin at these budnik M5

 

It is kind of about the effect. you car looks low but you don't have to deal with all the crap of actually being very low. scaping everywhere and a very harsh ride. you can go 20" rim and not drop to 1" drop. .

the real downside comes in the performance end of things. more rotating mass = slower stoping and acceleration but that is nothing 400-500 hp can't fix.

 

this sums it all up.........


if you run the right tire you could run 24's on a thirdgen with no issues assuming the wheel was built to the right spec.

 

As long as the overall tire height is the same, rim size will not make a difference in where the hub is in relation to the ground.

 

that is all true to a certain extent but 28" is usually pushing total diameter for a car. IT was too much on my mustang. 27 is about max not to rub.


at 245/30-24 would be 29.8". that would take some modifiy of something I am sure. I could be done but fab would be manditory.

my .02 would be to measure you clearance and diameter now. factor in what extra room you have. I would thing like a 245/45-20 would go just fine. that is like 26.8. that is 2" bigger than stock.

 

obviously would go thinner on the tire then 245/30/24 if you were going to do such a thing....you have to keep the dia dimensional.

 

Anyone have any pics of 20" iroc rims on a thridgen? was checking last nigh an my front tires are toast. hate to just replace them when I don't like the wheels on the car too much. might be a good time to upgrade the whole package. Tell the wife to work some overtime so I cam buy some wheels.

 

just search.....they are all over.

 

well I must be retarded then becasue I did search and I could not find pics of the 20" irocs. I think I am going to stick to 18's I would just like to take a look at a car with the 20's

 

20's out back.
I always thought a cool look would be a taller profile 20 out back (like a 295/40 29" tall) tucked up in the rear fenderwell. This would of course take some serious fenderwell work, but I think the overall look would be awesome. Kinda like the muscle machine die cast cars

 

and of course even with the taller tire out back the car would have to sit almost level. None of this stinkbug ****, although I do like a slight rake.

 

I'd say everyone keeps going for these huge rims, why are you going to spend say $4000 on some set of 20" ugly rims that dont match your car when you could get a very nice set of 17/18 wheels that would actually make it look good instead of like a tank or offroad vehicle ?

 

no harsh ride? pshhh, with tires with that low of a profile it doesn't matter how low the car sits, you'll feel every little bump since there's no sidewall to absorb the impact. You're not getting any performance out of it either.

400-500 hp? yeah, like everyone else on this board

 

the problem comes in the weight of the wheel which is where the harsh ride really comes. a low profile tire has no real cushion so when you run such a heavy setup on your car you not only slow it down greatly but you have a terrible ride because of the low profile necessary to use the wheel.

i like the looks don't get me wrong...that is when they are the same size all around and not the staggered size. however the weight of the wheels alone really kept me at 18"

 

hot wheels, hot wheels, hot wheels.....

 

I don't know where the 4k figure comes into play. $190 vs $250 is only $240 a set. tires are another say $120 a set. so $350 more for 20" irocs vs the 18's. If I liked them better I would run them. on my stang I ran into an issure of only be able to drop 2" so if I can't drop it over the 17" wheel I will put 20" wheels on. thus looking low. on my IROC I think I can run 18's and 1-1.5 drop and look okay. I ****ing hate fender gap. feder gap just kills the look of a car to me.

I will say in the pic above though I am not sure 20's are right for a thirdgen.

 

If you analyzie how many people are making that horsepower on these boards, then go and see how many people are running 20's the number might actually be the exact same if not more running 400-500 HP

Maybe i'm one of the few that has came to a stunning realization, that having a fast car with ridiculous amounts of power is WAY, WAY more fun then having a nice looking car........Granted i wouldn't throw a high HP engine into a rust bucket beater

DISTURBthePEACE, If performence isn't your concern.....which i may need a flame suit for the following comment, but i'm gonna assume that performence isn't your first priority judging by the lack of 2 cylinders in your car. I think in your own personal situation, you shouldn't judge weather to get 18's or 20's on the performence argument, and if you are talking about looks and attending shows, I would say some 20's with a really nice stance are a great improvement

 

Flyinlow is right, i dont really care about performance...I just want the looks right now. 20s are rare around here, they are only seen on trucks. I have a suspended license right now for to many speeding tickets anywayz. So when I say I want 20s, i want 20s. not 17s, not 18s, but 20s. Speed can bite a fat one for all im concerned, if I wanna go fast, I'll get on a bike. My car is for looks and puss, and if the car looks good, and your game is tight, then they dont care about missing 2 cylinders. "Most people show off by going fast, but the proud few show off standing still." And I, my friends, stand still.

 

I have 20's on my other car. rides better than my IROC.

as for 400 that is not that outragous. you can spray your way to that. that doesn't cost much.

my car does fine with the 20's. it does hurt my launch but a set of slicks fixes that up.

 

Didn't say it was outrageous, just sayhing hardly anyone on this board is making that kind of power. Most of the cars here are v6's driven by 16 yr old kids driving daddy's old beater.

Yeah, spray your way to 400 hp......real smart. Lets see, start out with an L98 that makes 215 hp, minor mods lets say 240....maybe, to get to 400 thats a 385 shot of juice.........yeah. And it'll still run 12's with any of these jokers driving. :lala: Doesn't cost much? HA! Let's tally up the cost of a DP nitrous setup and all the broken parts

I still think the 20's will be harsher than a smaller diameter wheel b/c it's going to have a shorter sidewall. Why do you think most luxury cars don't typically come with 15" wheels, and a few now come with 16's as an option. Bigger wheel = harsher ride.

 

That wasn't my point, Corky.

How would you know how much fun it is to drive a car with ridiculous amounts of power? Stock LS1?

 

Not trying to be an ***, but check your math. I do see your point. Most luxury cars do come with 16 or 17" wheels, and those that come with an 18" wheel usually run a 28" tall tire. Wheel weight does play a role in ride harshness, but everything I have read and tried has lead me to believe that the short sidewall is the major portion of the cause.

Here is another with 20's.

 

Flyinlow, you gotta admit, that is funny

 

ohh, his isn't just any stock LS1, it runs deep into the 11's

 

I guess I am talking about me. 90 iroc with a 350. my car stock was 245hp stock. has forged pistons. I would run a 150 shot on it if I wanted to make it a track car. I don't know what your talking about 385 shot of juice I think you math is a bit off there that would be over 600hp not 400hp.

as far as ride harshness I put 20" on my 01 mustang. went from 245/45-17 to 245/40-20's. no change in ride harshness. it does tramline more but it still did it stock. less sidwall does mean keep away from the curbs though.

I get the impression you just want to arue your point but dont' have experience to back it up. I ran a 150 shot of nitrous on my chevelle I only put 5 or 6 bottles through it but it held up just fine. pulled it off when did a head and cam swap and there was no damage. IT had no better parts in it than my stock engine in this car.

I am not trying to bust you *****. your points are some what valid on paper, it is just that I don't think you have 20"s or nitrous. there is a differece between real experience and opinion. maybe I am wrong and you have run 20" rims and a ton of power adders.

 

I was unaware that he has taken it to the track. Flyinlow, what were the times and mph?

 

it was sarcastic.

in another post, he siad it was a 12sec car, and should be in the 11's. He made that claim without ever running it at the track.

 

yeah, my math sucks, but it was a long day A 150 shot is alot of juice for the majority of the cars out there seeing as how most haven't built the motor to handle it. Never said I had 20's, or nitrous on MY car, but I do work at a speed shop as a tech so I think I have the experience Home to the countrys fastest n/a 4th gen.

 

Stock............Time to rethink that comment

LOL, Who said i was talking about driving my own car.......

Before you come up with some smart *** reply, make sure you know what the hell you are talking about

You don't own the shop, you don't own the country's fastest 4th Gen

 

Oops.

 

Is this a Photochop, or did Lance put 20"s on Blue?!?!

 

Welcome to last year...

an NX kit and some gaudy tack-on body pieces don't make it fast, stupid.

 

I might be wrong here, but wasnt this thread about wheel and tire fitment issues? Fellas cmon, grow up a bit.

 

Appearantly you missed the part where i mention i wasn't talking about my car.......

Did you miss over that while you were recounting your years and years of experience as a speed shop tech with the fastest 4th gen in the country........If you really want to start throwing around where people work as a source of credibility when it comes to nitrous oxide and turning large rotating masses we can..........

Gaudy tack-on pieces don't make my car fast? Did you learn that while working as a speed tech in a shop that's home to the fastest 4th Gen in the nation?? Maybe i've learned differently....

I could discredit your above statement all day long, but frankly, I don't find it worth my time to look up every luxury vehicle and get the stock wheels specs.....:lala: :lala:
