I am going with the PS4's myself and sticking with stock sizes. Believe me I wanted to put bigger sizes on front/rear BUT am not anymore because your speedo will be off plus I believe the rear 315's will be too big for the 11.5 stock rims even thou it will only be slightly off. I would also argue you wont see the difference (width of tire looking from the rear) from a 305 to 315.

My own opinion STOCK SIZE IS the way to go!

Nice setup. I was looking at those same ones.

You are talking only .5 mm each way from center. You won't notice even looking at them. You should not have any problems.

Just keep this mind...

ZL1 Front = 20-in x 10-in
ZL1 Rear = 20-in x 11-in

I went with the stock size PS4's. Looks and drives great. Really don't notice any difference in tire size at all.

I also have the Michelin PS4's on 20x10 and 20x11 polished wheels.
For weekend use I have 315/30/20 R88R's on another set of 20x11 polished wheels.

Hit another snag... Apparently Michelin doesn't make a PS4S in 315/30ZR20....

Ok got them mounted. WAY better look and ride. Only drove 9 miles but these things are the best. Big improvement in ride quality. I’m not worried about handling or anything because all I do is drag race and I have another set of wheels/tires for that. I just wanted a great cruising tire and these are them!

Here is the pirelli 305/30 rear. Looks stretched and short


Here is the Michelin 305/30 rear. Way better fit. More meat


Here is the Michelin 285/30 front

Yeah they look great. I'm going to get a set of PS 4S in ZLE sizes. I'm way too cautious / not confident on the stock good years.

You hit the nail in the head. I'm also way too cautious and concerned when driving in the stock tires (until they heat up).

I'm having PSP4s in stock size installed on my ZLE on Monday. I can't wait to experience the better ride when compared to the stock Good years.

By the way, how much are you guys paying to have tires mounted and balanced?

My dealer wants $400 ish for doing the job.

I just paid $100 plus $20 tip. The tire shop used a very nice corghi touchless mounting machine. Forgot the brand of the balancer but they looked new. The tech even torqued my titanium lug nuts properly.

$400 to mount and balance four tires is major BS- Like BMW level BS.

I know, the more I think about it the more I’m realizing I don’t want to pay stealership prizes. My appointment is on Monday, I’m gonna do some shopping around over the weekend to see what other pricing I can get.

My only reason to go to the dealership is that if they mangle my wheels it’ll be super easy for me to deal with them to get a replacement.
