This may be a noob question, but I was wondering if there is anyone who has the stock 18" wheel with 245/45/18 tires or possibly even 255/45/18 tires. I want to go with the thicker sidewall to kinda soften the ride, but I want to avoid rubbing issues, whether it'd be from the fender or inner wheel well.

Any advise is appreciated...

The wheels in question are on the car with the picture attached...

you going to stay with stock height?

with those tires, when you do hard lock turns, you might rub the front and rear of the wheel well a little bit

yeah everything is stock, except the lighting and tint. I have no suspension mods nor do I plan to put any. the stock tires are 245/40/18. The ones on there now are the Sumitomo HTRZ II.

I thought I could get away with the 245/45/18 for all four tires at the very least.

I really want to do the 245/45/18 for the front and 255/45/18 for the rear.

Rear will be fine for sure, the front rubs in the back of the wheel well into the plastic at about 30 degrees to the left (in left wheel well) or right (in right wheel well).....I run 245 45 18s....had those wheels you had, also my current OEM wheels have same exact specs 18x8 + 45

wow, you find the stock 245/40/18 tires not soft enough? i find my oem size is quite compliant, not jarring at all.

Does 255 fits on OEM 18*8 wheels? I thought that 255 is too wide for 18*8 and the maximum width for 8" should be 245. Someone please correct me.

personally i would never put 255 on 8 (didn't even know stock is 8).

you can do 225/60/r18, and ride like an SUV...........

only 1.x inches greater than spec.

the reason I ask is because a tire shop I inquired for falken tires said I can even go 275/35/18 on the rear if I wanted to, but insisted I keep the front 245/40/18 because it might rub.

I thought 275 is impossible just like Luoisp_p but apparantly the tire guy said he's installed it on the same car before.

I also thought the wheel width is 8.5?

If Eyekutr has rub issues on the front with the 245/45/18, i might just stay stock. Unless lowering the air pressure from 35 to 32 makes a difference...

I think that the stock wheels are soft enough, but I just want to improve it. Getting 17's will be last resort though lol...

should we move this to the tire section?

Im running stock 18's with 245's completely slammed and no rubbing so far And I dont think that 255 will fit the stockers.......even if they did I think they would look super ugly.....

stick with 245 40.....youll be better off

Stocks are supposed to be 245/40 mine is dumped and i barely rub on turns so if you were planning on lowering it with sizes you mentioned it would be all bad.

Stormforge

if you lower the air pressure in your tires, you will over time have uneven tire wear - 35 PSI is specified for a reason!

from what you've told us so far, i think 17" oem wheel/tire size is what you are looking for. your best bet would be to find someone who wants to trade 18"s for 17"s. i'm sure there are guys out there that would do this swap.

dunnojack

of course 255 would fit.
it's only 1cm wider than stock.
