Default Tire Size Help

Hey everyone, I'm having a little bit of trouble deciding on new tires for my car. I am running 18x8.5" wheels in the front, and 18x9.5" wheels in the back. In the best situation, I would run the following sizes:

Front: 245/35/18

Rear: 275/40/18

Are there any precautions that I would have to take running these size tires? (fender rolling, etc.)

Depends on the offset of the wheels.

I believe the offsets are:

Front: 38mm

Rear: 35mm

You'd want the fronts to be 40 and the rears 35, easier to tuck and evens out the look.

I have 40s in the front and 35s in the rear now and I don't like that look. I want the front to have a thinner tire and the back to have a thicker, beefier tire.

35 off set on the rear with a 275 will require a minor fender roll...

275/40 is kinda tall though... you would be better off with a 275/35-18...

I'd also (wait, I do) run a 255/35-18 on the front... then, if you really want a wide tire, run a 285/35-18 on the rear and roll the fender to the max...

I wanted to run a 40 so it would have more of a sidewall. The low-profile tires are cool, but I just wanted to have something that looks more substantial to me on there. I've been wanting to get my fenders rolled for a long time, and this might be the extra incentive to do so.
