I know 20s are generally frowned upon here but if not gaudy tin foil plate looking things it can look great if done right and i know there are a few of you who are running them. I'm concidering a staggered 18 x 8.5 fronts/20 x9.5 rears setup on my 92 camaro but am unsure of what tire size i can fit on the rear. Any help would be appreciated.

These are the wheels if it helps.

I am running 20" wheels, and my current wheel/tire combo has plenty of clearance in the fender wells.

I am running a 20x9 wheel in the front. 245/35/20

A 20x10.5 in the rear with 255/35/20. I ran a 275 in the rear, but it rubbed some. The fender needed to be rolled to fit that size tire.


Be sure to post pictures if you go with a 18/20 setup. I am thinking about going that size.

Fenders will be rolled, no worries. I figured I'd have to do that anyway with the car being dropped too. But that helps tremendously. I think the 255 series tire would work better with a 9.5" wheel anyway. Thank you

I'm running a 20x9.5 in the rear and a 275 30 20, stock height and the fenders are not rolled. It has only rubbed one time, I was doing about 75 on the highway and hit a pretty big dip in the road while going to an out of town car show. I had a passenger, 2 tents, an ez up canopy, a small charcoal grill and a full cooler in it.

Yes but im going to be dropped at least 1.5" so if nothing more than piece of mind ill roll the fenders. Any side shots of your cars guys?

These are the only side shots I have of mine

Nice stance! Which spacer are you using on front and rears? Is your car lowered? I know I am crazy, I am looking foward to swap my Ronal's for a set offre 20X8 fronts and 20X10 rears. As for the rear tirés, I would like to go with 295/25/20. Would it be fine with à 1'' lowered on Eibach prochaine kit?

It is stock height, I have 1.5" of space between the tire and the fender lip. 2" spacers front and rear, but I would go with 1.75" in the front if I were going to do it again due to a slight rub on the ground effect if I am turning and hit a bump at the same time.

I posted above, here are some pics.


Before lowering.


Another picture, after it was lowered, don't have any good ones of the entire car with the new stance

i have those rims in the 18s. i really like them

Ok, so I decided on and bought the wheels. I went with Boss Motorsports 338s with the black center and polished lip. 18" x 8.5" fronts and 20" x 10" in the rear. They look awesome. Now I'm working on getting tires.

Question, for the rears is a 255/35/20 or a 245/35/20 on a 10" wide wheel safe? I know you BuggyDisaster said you're running 255s but I don't know if the car is your daily driver. This is my daily. I understand the sidewalls will be stretched but will they be safe? Import guys do this kinda set up all the time. I'm just worried about rubbing.... any input?

Every manufacturer has a recommended wheel width range they recommend for a certain size tire.

A 275/40R17 is commonly recommended to be mounted to a 17x9" up to 17x11" for example.

Any change in profile (40,) and section width (275,) can change recommended wheel mounting width. Wheel height usually doesn't change the range recommended.

Start with that recommended range. If it's within the recommended wheel widths to put it on a 10" wide wheel, you're good. If it's only recommened up to 9.5" but that's the look you're dead set on, it might be okay.

JMNVFHO.

What if you can't find the wheel width range for a particular tire?

NVM, I'm just going to go with the 275 tire and not worry about it. The more and more I look at the stretched tire look the more it bugs me. I'll post pics once everything is together.

Call Mom.

I did but my mom doesn't know **** about tires! Lol

Looks good. What is width of rear wheel

20" x 10". Running a 275/30/20 tire

I know this is an old thread but are you still running with this setup? If so how are you liking it?

I'm not against 20" wheels by any means, but on a 3rd gen - which needs a 26" tire, the visual and performance virtues are compromised compared to say a 5th gen Camaro or SRT Mopar.

Many people don't understand this, but the smaller the tire sidewall, the higher the effective spring rate of your car (and therefore, lower ride quality). If you live in areas where roads are smooth and not cratered, 20" may be a perfect choice, otherwise a 18" (or even 17") is a much better choice for most. The inflection point (point of diminishing returns) for a 26" tire on a 3rd gen comes out to be 18" wheels in real world driving and performance (street and track).

Even the track hero 5th gen Z28 uses 19" wheels and tires due to both weight concerns and also having the optimal tire sidewall:wheel ratio for the best handling and control.

I can't turn my wheel at all on my 87 with 2 inch adapters that I was told were needed how did you get yours to turn? Fronts are 245/40r20 rears are 275/35r20 on 2017 ss rims

20s are too big for a thirdgen. Get proper-size wheels & tires and you won't have those problems...

my backs fit fine with 275/35s and a 20x9.5 wheel but the fronts hit the fender immediately when I turn the wheel on the back side closest to the door . Im running 245/40s on the front with a 8.5inch wheel 2 inch adapters all the way around. Any idea what i need to do in the front other than cutting anything? Would a 1.5 inch adapters up front help?

Get the proper-size wheels & tires...

well i just figured they'd look good .they are camaro rims at the end of the day and other people are running them in this size but after doing exactly what others say they've done it definitely doesn't work for my car in the front anyway. If I had 18 inch iroc rims id gladly put those on but this is what i have and can't really afford to just go buy another set right now.

Tall tires
Lowered suspension
Wheel sticking out too far

All these things work against your ability to turn the front wheels. You got all three going on at the same time.

That front tire is almost 28 inches tall. Most of us have 25-26 inch tall tires. My 275/35-18 fronts actually measure 25.5 tall. Soooo, I'd either cut out your fenders/wheel wells to make more room or get a smaller tire/wheel. Both will work. One makes more sense than the other though.

stock height, i guess 40 series could be kinda too big ,but im gonna try to bring the wheel in with a 1.5inch adapter instead of the 2 inch that was recommended by hawks.

definitely not cutting anything on the car, I'm gonna try smaller adapters and bring it in a half inch if that doesn't work at all then I'll just sell the rims and tires im not doing all kinds of stuff just to make them fit its just dumb at this point tbh..

Forum member Zach/90\irocZ has been running taller 19 inch wheels and tires for many years of many sizes including 45 series. I'd search for posts by him.

ok thank yoy

By that do you mean the vehicle still has original springs, or you have new springs advertised as stock replacement?

40 year old original springs aren't stock height anymore. In your photo it appears that the front has drooped quite a lot. Stock spring rates also are far too soft to be having a tire out that far. People typically use 800 to 1100 lb/in spring rates when tires are located under the fender lip like that.

They are WHEELS, not "rims"...

From here, it looks to me like you may need spacers/adapters that are closer to 1" thick. I don't think losing .5" is going to cut it.

yeah i mean I haven't changed them, the back sits pretty high and the front is lower than normal because my driveway is angled but the front definitely sits lower also there's a 350 in it not the original 305 im guessing weighs a little more however slight it might be
