Folks,

I am just about to pull the trigger on some Rohana RFX11 wheels and I have pondering what offsets and wheel width to run both front and rear and what tire sizes. Please help me My goal is to go as aggressive as possible without any rubber peaking past any fender not even by the width of a hair strand. Homie don't play that. Here are my options:

Front: 20 x 9 +25, +35
Tire: 255/35/20 or 265/35/20

Rear: 20 x 10 +33; 20 x 10.5 +35
Tire: 285/30/20; 295/30/20

I am most concerned with the 295s on the 10.5s in the rear as I will be lowering the car ever so slightly on MSS Sport springs which are height adjustable. Let me know your thoughts. I have a 2021 G30.

I am running R20s… 9 x 10” rims with 275/35 front and 295/30 rear.

The wheel wells are filled and I would caution going any bigger in front.

After long deliberation, for good wheel rim sidewall stance, I recommend having 1.5-1.8” more width in tire vs rim. Less and rim will appear past sidewall and susceptible to damage.

Picture for reference.

I was under the impression 265's+ on the fronts was a rubbing risk when lowered. This is why the M5 has wider front wings for a 28 offset 9.5" wheel.

So 295 on a 10 inch rim looks good. I think it will be fine on a 10.5 inch wheel as there appears to be slightly more space without them sticking outside the fender. 265 on 9 inch rim also seems doable in the front. Thanks for the pics!

The wider fenders on the M5 allow it to run up to 295s in the front if the wheel offset is perfect.

Rodder, could you please post pictures of side shots and rear of your car. What offsets are you running on those wheels? I am starting to think I should stick with 10s +33 instead of 10.5s with +35 in the rear and running 295s. Your 295s on 10s appear to be pretty much it before sticking out the fender.
