Have a '10 X Sedan w/ Cusco strut bar and a Coupe Journey/Sport RSB (can't remember which one). Currently running 225/50 - 18 all way around. Thinking of getting 255/45 for the back wheels to beef up the looks from behind. Will this really mess up the handling that I'm used to? This car is driven once in awhile and only sometimes will I push it (maybe up to 8/10) on a back road. Again, the priority in doing this is for looks, but at same time, I don't want to degrade the handling too much.

Thanks to any who can offer advice.

What width are your 18s? if they are OEM 7.5" width I'd stick w/ 225s, the wider 255s on a 7.5" will have more flex in the sidewalls. Also w/ AWD you should run all the same tire size all around or be 1% or less diameter difference front to back.

Was thinking of doing 245/45 all way around but I just got these wheels/tires mounted last year and have only put about 4500 miles on the tires.
I just hate the way the 225's look from behind, look like toothpicks. Guess I should've just done 245's when I got the wheels.

Even with the 255's in back (wheels are 8" wide, aftermarket Enkei), the diameter diff is only .6% different (according to rimsntires calculator). 8" is the bare min for the 255 so it should be within requirements.
Guess I'll just leave them be as I'll probably get rid of this car next year.

Thanks for the feedback.
