Just picked up some wheels

F: 18x9.5, 40 mm
R: 18x10.5, 45 mm

What do I need to do modification wise to fit

F: 255/35
R: 295/30

vs

F: 265/35
R: 315/30

Thanks!
No modifications to the fenders needed. Both front and rear wheels will be sucked into the fenders. Fronts will be 4mm sucked into the fender and the rears will be 10mm sucked into the fenders.

You can run a 265/35/18 front and 295/30/18 rear. 315 is too much for a 10.5" wheel.

F: 265/35 no modifications needed
R: 295/30 cut fenders. With a 285 you might be able to keep the stock fenders
315 is to wide for the wheel.

So which is it, hehe? The 295 will fit fine or will it require me to roll/cut the fenders? :)

For the 265 up front, I won't need to remove fender liner or anything like that?

Tire rack actually has 10.5 within the recommend rim width range for the 315.

You'll never have to remove the fender liner on the front unless you go way past the fender.

The 295 will fit the 10.5 perfectly. On a stock height car, they shouldn't rub the fenders but not all cars are the same and the wheel alignment also plays a part.

I don't care what tire rack says. A 315 needs a 11.5 to fit properly. Plus, you'll never fit them without rolling the rear fenders.

Hi.
I just install my new wheels and the front caliber was touching the rims, so I installed a 3 mm spacer at the front and now its clear, but nothing space ( < 1 mm) between rim and caliber. Should I mount a 5 mm spacer instead? And how much clearence should there be? I think when I will brake with the car, the caliber can move a bit.

Its up to you. Some of the wheel fitments I have done on my cars clear the brakes by a sheet of paper LOL. A mm is a lot more than that. You caliper won't move but if you get a rock/pebble stuck in there it will scratch the caliper.

Also, a 3mm is what I feel the safest size one can run using stock studs. A 5mm is pushing it and I don't think you'll get enough turns on your lugnuts to make it safe.
