i don't know, how willing are you to do fender modifications and run stretched tires?

because if you're not willing to, then the answer is "no".

i already have rolled rear fenders, what other modifications would i have to do? i'm willing to run stretched tires.

slight pull on all four corners.

225/35-19 in the front, 255/35-19 in the rear.

Hi, I'm driving a IS250 RWD
Will 19x8.5 +35 (front) and 19x9.5 +32 (rear) fit? 　I think the front is fine but not sure about the rear, and what tire size should I run if it fits?
Thanks

itll fit no problem my friend do you wanna mod yours fenders. if not run 235/35 rear 215/35 front. if you do run 225/35 front and up to a 265/35 in the rear. also how much if any are you going to drop the car.

Thanks for your help, I'm not planning to mod the fenders yet but will lower with Tanabe Nf210 about an inch. Any lower will not allow me to get out of my parking lot. Thanks again.

^ given your proposed wheel and suspension specs, you can probably run up to 225/35-19 up front and 245/35-19 and still not need fender modifications.

255/35-19 in the rear might be close, but you should have enough clearance.

^ i was running 19x9.5 +30 with a 265 / 30 / 19 and i cleared no problem. Front you can get away with a 235/35/19. You just need to heatgun the little dimple ont he plastic linear so you wont rub on full lock uturns

^ 265/30-19 is a little over an inch shorter than 255/40-18, which translates to about 1/2" more of a "gap" between the top of the tire and the fender.

Im looking at the concept one cs-5.0 wheel.
specs are 20x9 F +36, and 20x10.5 R +45
tech from concept one said go with 245/30 F and 285 R (jesus)

Will the offset work? I was thinking 235/30 and 275/30

Not really, the wheel is also an inch taller. So there will be no more gap with a 19 and that size.

265/30-19
sidewall height:
265 x 0.30 = 79.5 mm = 7.95 cm = ~3.6"
total diameter:
19" + 2 x 3.6" = ~26.22"

255/40-18
sidewall height:
225 x 0.40 = 102 mm = 10.2 cm = ~4.6"
total diameter:
18" + 2 x 4.6" = ~27.27"

difference in total (tread-to-tread) diameter is about an inch.

(continued from previous post)

measured from the center point of the tire, the difference in the radii of the two sizes is about 1/2" with 265/30-19 being the shorter tire.

that 1/2" translates into an increased tire-to-fender gap.

thanks for reading.

haha you must be bored to go though all that just to make a post! wheel "gap" is all dependent on ride height. It doesn't matter what size the tires are if they car is not low, they will be GAP.

Thanks for reading.
