I just purchased a set of BC Forged 19s for my ZL1 and I'm trying to get an idea of what tire size I should go with. I really don't know much about tire sizes besides the little information I see here and there.

19x10 Et. 23 front
19x11.5 Et. 49 rear

Lighter weight rims and running 325s in the rear is my goal. Anyone on here do something similar? Also, I don't know if the tire-to-fender gap is going to get bigger so I was considering putting some BMR lowering springs on it if the gap is too big. That's just an idea though.

Lastly, did you guys do anything to correct the speedometer? I'm assuming going down a size will mess with the speed readout and what not. Is there even a way to correct that?

I'm very much mechanically inclined but I don't know shit about rims and tires. Thanks for your help and input guys.

285-295/35/19 325/35/19 would work just fine what tires are you going to be running?

I run 285 all around in summer, 275 in winter.


Next go around, I'll probably up rears to 305.

The ZLE has 19s, 305 front, 325 rear. 19×10 front, 19×12 rear. Don't remember offset.

Honestly, I'm not sure. I was looking at the Michelin PS4S because I hear most people on here talk about how good of a tire it is. Those tires are not cheap though. I love the performance of the stock tires, I just want something that I don't feel like I'm going to die when I drive in the rain. I'm open to other tire choices though.

Pretty sure a 325/35/19 does not exist or at least no one has it.

Check out a 345/30/19. It’ll be crazy wide but about the same height as stock

325/30R19 will fit on the 19x11's in the rear and isnt too much shorter than stock.

I have the APEX 19x10 ET20 and 19x11 ET43's on 275/35R19 Pilot Sport 4S fronts and 295/35R19 MO1 Pilot Sport 4S Rears. Ride height is down 0.1" evenly front to back. Runs great, nice increase in pep. 35lbs or so lighter total.

Any noticeable loss in traction or grip since you’ve gone to a thinner tire in the rear? The weight savings definitely appeals to me but I’m curious if it negatively affects your grip. I feel like my car would just turn into a tire-burner with a 295. Granted, that’s only a smidge smaller than the stock 305s but still. I know the car can break the tires loose very easily either way but I want to put a little more effort into it before they spin.

I believe that was a “problem” with the hellcats when they came out. All that power on 285s.

this should have all the info you need as far as wheel size, tire size, etc.

it also has a handy dandy interface where you can put in what you have, and what you want to go to, and it'll tell you the differences in all sort of metrics.

It's been super helpful to me in the past, not only on my camaros, but other cars as well (just change the make and model obviously)

I'm running a 305 front and a 355 rear currently on mine for track and autocross use

Yes a bit less traction but even if you go to 325/30R19's, you will have MORE traction and net weight will go down 28-30lbs overall net, and you're dropping the diameter of the wheels which brings the weight (which is less too) center to the rotational center which helps reduce inertia. You will notice the change, I promise lol, even on 325/30R19's rear.
