Im running 18x8 Rota D2 with a 48 offset. with 225/40/18 on Df springs. Thinking or puttin 235/40/18 on this summer. will i have a problem. Also thinking of running 265/35/18 in the rear. any thought on fitment on the 235 or 265's

let me know what you find out in the rear as well , although my offset is at 35mm in the rear. will the 265's set off the vsc on the vehicle being too high?

265 seems like a bit much...tC1?

Not only does it seem like a bit much, it is a bit much.

Ideally, 265/35-18 tires should be run on a rim width of 9-10.5 inches. On 8" wide wheels, the sidewall bulge will cause the wheels/ride to feel like they're squirming around on the pavement.

No, not with the 35 series profile. Calculations for comparison:

205/55-16 (OEM) outside tire diameter = 24.88"
225/40-18 outside tire diameter = 25.09"
265/35-18 outside tire diameter = 25.30"

225/45-17 outside tire diameter = 24.97" front
245/40-18 outside tire diameter = 25.72" rear
is what I'm running, and no vsc or ebd problems due to the difference.

Cionide post a pic here , so i can see what it looks like with the different side wall height please.

If you're talking about mine, the front and rear are almost the same sidewall height, even though the tire diameters are almost an inch apart, because I'm running 17's up front and 18's in the rear. Here's my full story and a pic:

18x8 +45
with fender rolling forsure, will 245 40 18 fit all around?

Expect some rubbing on the front fender liner if you have a heavy drop...
245/40-18 is 1" larger in outside diameter than OEM.

i have the hotchkis drop

^^ rub rub rub.

How about 235

papo

i think a 265 on an xb is overkill specially on the rear, max i would try to run on the rear of this car would be a 245/40.

235/40 on 18x8 +45 might not even need fender rolling on the Hotchkis drop.

Well with dips and weight in back my 225/40/18 get chewed up by fender
