will a 305 35 20 throw off the computer?
 

Hello I had 305 35 20 and 275 45 20 on my 5th gen Camaro and was wandering if I could run them on then 6th gen or would it set off the computer? Thanks

No problems here but check clearances. Inside rear drivers side is a harness bulge front. 45s in front? I run 35s F/R.

There is a you-tube video that shows how to move the harness in the driver's side rear. It looks really simple. I am doing it tomorrow morning because my tires are HERE! If i have time i will take some pics and maybe do a writeup.
Bybcous... I think, is running 305-35-20 and 285-35-20 with zero issues on aftermarket wheels. That's what I ordered so I will know tomorrow.

Just got mine on today. No rubbing yet. 305/35-20 in rear on 20x11 wheels. At 65 mph you will be off on your speedo by about 2mph. You will actually read 2mph higher than actual at 65 according to an online calculator. If you have a Garmin GPS that shows your speed you can verify this.

What is your wheel and tire setup?

I just installed mine today too!

20" Front Size: 20x10.0 with 28mm 285-35 | Rear Size: 20x11.0 with 43mm 305-35

I moved the harness in the rear and no rubbing
I needed a spacer in the front

Is your car lowered?? What thickness for you spacer??

Not lowered...yet.

Appears to be a 1/4" spacer. The tire store did it when I wasn't there. The guy has a 5th gen so I told him to drive it around. He said it wouldn't go without the spacer, like the brakes were on.
Not sure if I could go with a thinner one. I can't get my fingers between the tire/strut.

MRR 228s

20x10 fronts
BFG Comp 2 285/35-20

20x11 rears
BFG Comp 2 305/35-20

Basically stock tire sizes from 2014 ZL1 (Tire Rack)

So do we have to run spacers with the 228's. Mine are ordered and I was planning on running 275/35 front and 305/35 rear.

thanks,

You'll be fine upfront with the 275/35 combo. its the 275/40 or 285/35 that has issues

I have 285/35 on front with no issues

more than one person runs 285-35-20 with 228s with no issues. I think I am the first to try it with these wheels. I need to pull the front wheel and see if I can use a smaller spacer or do a little clearancing. Kinda doubtful but that was the only size spacer they had.

I don't think it will rub if I lower it. Just a little bit more poke than I like. The back is perfect.

Can you take a picture from the back to the front? Interested on seeing how they sit in the fender?
