I have a 2015 C7 Z51 with Black 19`s front and 20`s out back. What size rims do I have and what is the widest tire I can fit on the back 20`s? I have the stock height ride. Thanks!

Thanks, really curious what size tire I can run on the back. Don`t like the 285`s out back!!

Don't know how much clearance those cars have but if you're wanting to know how big of a tire will fit on a 20x10 I'd say that wouldn't go any bigger than a 305. 295's fit perfect if you ask me. It's also going to depend on the brand. Some brand run wide and some run skinny.

You know that car has an intelligently developed chassis. The redneck approach of "more tire is better" doesn't really apply with that car

So his stock tire size vs a wider tire size would have the same results for traction??

Lol smh

not in so many words. lol but why would anyone mess with what works? that car will run with exotics.

Depending on power goals I would say you have a point to a point. However, I don't necessarily believe the redneck analogy. Wider tires do generally net more traction.

Beard, I would look at brand and type for traction before going bigger. Did you get rid of the Camaro and go Corvette or are you expanding the stable?

redneck was just a joke. context is a bitch. on forums. im on the redneck quest currently with my RX8

You'll probably need wider wheels to run much wider tires (plus the fender flares to go along with it). I fit 305s on a 10.5" wide wheel and that's probably the limit for that width.
