Hi guys,

I have been looking at post for a long time now and still cant figure out if my idea is going to work i want to set up my car for drag racing but still use it as a daly driver for summer, i have winter wheels and tires tacken care of. i am think ing i want either 15x10 ro 15x8 wheels for the bac specifically the centerline telstar's. i was also wondering if 4.5 or 5.0 back spacing would best fit my application. i am looking at somethign like ither a 275/50/15 or a 295/50/15, i would perfer not to have to massage my fender wells, if it is a difficult thing to do. also i dont know if it is neccisary to roll the out fender lip, and exactly how you do that cleanly.

For the front i think i have decided on 15x6's with 3.5" back spacing, and 225/50/15 tires which according to my math should work, do you agree?

Thanks for any suggestions remember i do drive this car for a dayly diver, over the summer atleast but i do drag race so i would like to get the best possible traction i plan on starting with radial t/a's then getting drag radials once the funds come in.

Thanks again,
ELi

with 15x10's, 275 or 295 will fit. with 15x8, the largest i would go is 265

raptere

yea but the thing i am really wondering about is what is the correct back spacing and will there be any rubbing, or modificatino if i were to lets say get the 5" back spacing and the bfgood rich tadial t/a's if they have a 12.2" total with.

raptere

come on guys i know you all have done or have heard about people that have done these kinds of things with their wheel tire combonations so please share your info with me!

Thanks again
later,

Also please relocate this post if it would get more replys somewhere else.

Dude...those are nuts...I would go with something like 15x9. Its not like you are going to need 10+inches of grip unless your are really racing.

Here are my new 17x8 for the front and 17x9 for the back. I think they are plenty big enough.

if you run 15x8's you can run 295's without much massaging. I run 15x10's with 295's and had to do a little work on the inner fender and roll the lip. I run 5.5" of backspacing and they fit just about perfect.

295's will fit all day long. look at the 295's measurements against a 26x11.5x16 et street. ive run them, no problems. tap in the inner fender a bit near the control arm and you will be fine.

raptere

the thing is the wheels i want come only in 8 and 10 inch withs, that is why i want the tens and the bigger ones look cooler too, but ive heard 5" back spacing does that sound right and will massaging still be neccisary?

o yea and do thoes number sound fine for the front?

thanks for the help some pics would be awosome too, thanks again,

with only 5" of backspacing on a 10" rim the tire will hang out of the fenderwell. 5" on an 8" should be more than enough.

i would recomend a 4.5" back spacing for the front and rear. 10" rim doesnt do much for you on the street.

raptere

if you say 4.5, then does that mean you suggest only the 8"? and i want these for the streat and the strip, what i think i really do want is the 10's with the 295's and it sounds like for tht size i am going to need the 5" backspacing, so will thhis work for me?
sry if it seems like im asking the same questino over and over but i still cant find an answer in all your posts.

and will the front with toes specs still be about flush with the outside of the car? i want smaller , lighter wheels up front to shift the weight back for racing.

Thanks again for all the continuing guidance,

ive never ran a 10" rim on the rear. if all you are putting on is a set of 295/50/15, i do not see a benefit. if you had some 26 or 28" et streets or slicks, it may be worth a bit on your 60ft at the track. stick with the 8" rim in case you ever want to move away from a 295 tire, IMO.

raptere

that is a valid point.
What i was thinking though was thoes are only going to be for my summer tires and racing tires, i do plan on getting some drag radials also later in the summer.

I was under the impression that i could fit both a 295 and a 275 on a 10" rim, yet would i be able to fit one or both of toes sizes on an 8.5" rim whihc i think the telstars are offered in, and if i go with the 8" then is the 4.5" bs enough for a bigg... tire or should i go for the 5?

Min. recomended rim widths for goodrich TA
275/50/15 is 7.5"
295/50/15 is 8.0"

sweet then mabe i should just keep it simple with the 8" wheels and 4.5 backspacing, especially if i can still fit my crazy big 295's! mabe ill stick to something more stock ish for the front too, because i was just ghinking even if you go smaller with the front to save front weight, will it still mess up your breaking ability?

Thanks again guys!

raptere

so you guys agree thoes wheels and tires i described in the last post should fit?

i htink i am about ready to order them, and ill be sure to post when they're on.

YES OR NO

you will be fine with the 295 on an 8 inch rim . can't help with back spacing cause when I got my maro the 295s were already on the stock 7 inch rims. not many tire shops would want to put them on a stock rim ( I worried a little while but they stayed on through 6 trips to kansas from phx and 2 years) the only prob I had with rubbing was when I had two adults and the amp and woofer box in the back.

I had BFG Radial T/a's on a 15x8 rim, P275/60r15's, in the rear. The sidewall didn't look bubbled out- but then again, don't know how a P275/50 would look.

When I had P255/70r15's on the 15x8 rim in the back, I had to massage the driver's side inner wheelwell with a sledgehammer to make them fit. I only needed a 1/2 inch clearance... I had to bang in the section of the inner wheelwell at the bottom, between the door and the tire- it was scraping the sidewall.

hmmmmm, that sounds interesting with the 295's on the factory rims and no rubbing, yet i would wonder is the secton with wider if i have an 8" rim insted of the 7" you said you had? and would that be too much about how much room do you have on ither side of the tire with that set up?

raptere

also was your 295 a 50 or 60 profile tire? Pic?

Here are a couple pics of my rims and tires on my camaro. I know they are not 275's or 295's but they are 12.5 section width and it was said earlier that the 295's were 12.2 section width, so it should be a valid comparison, only .3 inch difference.

I am using 15x10 weld draglites and 28x12.50 MT ET Streets. The rims are of 5.5 inch back spacing and my axels are 1 inch narrower than with the original rear. So effective backspacing is 6.5 inches.

As I had to do was no outer wheel well lip rolling but a lot of inner wheelwell work. As I am not using the spring pockets so I cut them out and in the front of the inner wheelwell I had to cut but then again a 295/50/15 is about 2inches shorter tire so that cutting may not even be needed. Just a swift smack with a choice heavy object.

I would say 6inches of backspacing with the 295/50/15 and you would be golden. Just do some measuring to be sure but I would bet on it.

Here are couple pics of mine for referance

last one, hope this can help

man that looks like if fits perfect on you car. only hting is i was looking at the inside of the stock set up fender well and susspension, and there seems to be suspension hardware right back there that cant really be moved it only looks like i have aoubt another inch or so the way i am set up right now and that is with 245/50/16 on eight inch wheels stock.

so i dont know if that kind of back spacing will work right for me, yet if i go with the eight inche wheel the is two inches shorter. So your 6" with a 10" wheel is one more than half , then would the 5, or i was thinking the 4.5, work for the 8" wheel because the 5 atleast is one more than half of eight? This math stiff is really starting to confuse me i have been do ing calculations all week and i am just not sure on any thing.

Or would it just be saffer to just go with a 275/50/15 insted of the 295, because with out serioud modification i just dont see exactly how this is going to work, but then what would i need for the 275's. Does this thought process sound righgt? i am starting to concuse my self, lol.

See if you can help me decode my problem and come up with a safe and reliable answer, thanks agian guys

ps the drag radials i want to get latter on are only 275's any way so mabe it would be easier to just stick with that size now any way

Thanks again

sorry I was out of town on a run . the middle of the tread was wearing a little faster than the outside so I ran them with 26 lbs. that seemed to work a little better. I would roll the lip if I were you to be safe its not hard I took a 5 lb sledge and a hack saw and cut slits so the lip wouldnt warp the outside metal just be gentle and finesse it don't try to do it in one whack. the section should be as wide I would think but I never had a wider rim to try to compare I have a set of 98 camaro rims that I'm getting ready to put on and I need to look at what is out there to give me the same effective look. they are the 16 by 8.5s . as for back space blown 83 sounds right and though I would check meaqsure ments first I think I would go along with that. I didnt clearance the inside of the wells and I should have clarified that during hard cornering the tire did rub on the inside but it was just enough to rub the under coat off and shine the metal it didnt hurt the tire any. if this pic doesn't attach then go to my web and see my old pics to see how it looked. the tire size was 295/50/15

raptere

So, I apriciate all of your guys help on fitting these 295's but it dosent look like that is going to be practical for me i dont want to have to modify the wheel well much beyond mabe rolling the lip, so what about just 275's can i fit thoes on a 8 or 10 inch wide rim, with mabe 4.5 or 5 inches of back spacing and a tire that has a section with of about 11.2 inches?

Sory for the big change in direction, but i would expect much more reasonable and safe results out of this set up.

Thanks again guys,
