does anyone know 18x8.5 +30offset, 235/40/18 tires fit without rubbing fender?

 

yeah it should fit since I've seen people fit 275's with 9.5 rims with a +45 offset.

275-235 = 40 (tire overall width) (narrower)
40/2 = 20 (tire width per side) (narrower)
45-30 = 15 (since your tire is 20mm narrower and your offset is only 15mm lower it should fit with no problem. hell you could even run a 245 tire if you wanted)

they will fit, but they are going to be way to the outside of the car...

beers

 

would they be?

i mean I think my math is right so it shouldn't stick out any more than the guys running 275's all around

 

i have 18x8.5 +30 with 235/40R18....it's flush. no modification needed...even with the car lowered.

 

rather than start a new thread, what about a 265/30 on a 19X9.5 wheel, with +35 offset. the car is on coilovers too, so it sits lower than stock. I am test fitting them this weekend, but just curious.

 

9.5" should fit perfect.

 

The outer edge of the rim will be 26mm farther to the outside than stock. Go from there.

 

Oops sorry. I meant 9.5 should fit the tires perfectly, but I think they'll rub.

 

they will fit and they wont rub!

 

well, they are on the car. they fit, and do not rub...yet. I think I am going to roll the rear fenders, just to be on the safe side. if the rear suspension compressed all the way, say on a freeway on ramp, they would rub more than just a little. so, time to roll some fenders.

 

Pics?

 

sorry, had not gotten to that point first thing this am, had to let the sun come up.

car is dirty, it will get washed and shined tonight.

 

looks good- are you the same size/offsett on all 4s?

 

no, IIRC, +42 on the front, and +35 on the rear.
