Will it fit ?

Dadzl1 · 11-06-2023, 08:18 AM

Shopping for tires on my 2018 zl1. No one rides in the rear ( not that any adult would fit ) . Anyone know the limits ? Looking at this , BFGoodrich G-Force Comp-2 A/S Plus All-Season Radial Car Tire for Ultra-High Performance, 305/35ZR20 104Y. I don’t use it in the rain or slow. But I’d like to drive it a little longer ( 40-50s ) . Before the snow and salt arrive . Also 285/35 zr20 on the front .thanks in advance .

At almost 28.5” not without rubbing I’m guessing

Should be fine in the front and rear but since you have a 2018. You should relocate the wiring harness located in the driver left rear wheel well.

Yes, it will fit, this is what I'm running as a compromise, although with Michelin PS4S tires.

Two things, first, as Vigilante375 mentioned, make sure you relocate the driver side body wiring harness (see how-to here); second, the fronts may rub the wheel well liner every so slightly at full lock, so expect some wear, particularly on the driver side. This taller wheel/tire combination doesn't exactly help real world performance either.

In other words, while this setup works (and looks pretty nice if I may say so, see my avatar picture), it isn't recommended. My next tire purchase will be a different, shorter sized combo.

I have a 2018 and I am running the Nitto RIII 305/35 20 in the rear and they don't rub.

Yes, I have pulled both rears to look for rubbing and possibly relocate the harness. Was not necessary, does NOT rub.

I would recommend a set of rock guards with those tires. I have ACS Composite rock guards on both my 1LE and my ZL1.

Yep, either PPF up to the respective body lines or rock guards. The ACS guards are good looking too.
