Z28 Wheel size - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hey guys I have a 2012 Camaro SS with it looks like the 2015 Z28 wheels on it. Well my son has a new 2021 Camaro and wants some wheels like mine but I'm not sure what size they are. They are 20" matt black with 305X35 in the rear and 285X45 in the front. Can anyone tell me by the tire size in the rear, what the wheel size is? Or can I just put a tape measure through the holes in the wheel and get an accurate measurement that way? Thanks

Probably 10's and 11's but could be 9's and 10's

If they are 20", they are not original Z28 wheels. I think they are MRR and you should be able to find their specs on here.

285/35 (are they 285/45 or 35?) on 20x10 front and 305/35 on 20x11 rear are the factory ZL1 tire and wheel sizes so they're probably 10 and 11 wide.

yeah there 285/35 in the front. bf Goodrich comp-2. so I seen some on the web with those size tires that are 20X10 and 20X11 and 20X9 and 20X10. would a 305/35 fit on a 10" wheel?

Yes, that is the min width spec for many 305/35s

Man your car sure looks sharp. I almost bought a car Camaro in your color before I bought mine but I was scared to buy it because it was from a private seller. I just feel more comfortable buying from a dealership.
