I hope atleast a 235 ..idk why I just hate the idea of a skinny tire up front
Ok...... after calculations, the absolute closest matching fitment for the front on a 9.5" wheel would be a - 229/39-18.

Obviously that doesn't exist LOL

So your choices are a little to the left or a little to the right, there is no available match with a 255/35. If you had a 255/30, there's a match, but not a 35 - at least not when you do all the measurements.

So again - rear end is a 255/35-18; sidewall height is 3.51", overall diameter 25.03", section width (tread width) is about 10" (0.5" less than wheel width).

On an 18x9.5" front you can get close with a 225/40-18, which has the closest matching sidewall at 3.54" - a mere 0.03" TALLER in sidewall height. Overall diameter is 25.09", or 0.06" TALLER compared to the 255/35 rear. Both of these differences are most likely not noticeable at all, you can get that much variation just by having different air pressures in the tires. HOWEVER the 225/40-18 has an 8.86" section width - 0.64" less width than the 9.5 wheel, so the stretch will be a little more round than the 255/35 rear.

In comparison, your wish of a 235 won't match stretch to begin with since a 235 is about 9.25" section width, only 0.25" narrower than the 9.5 wheel. Remember the 255/35 is 0.5" less width compared to the 10.5" rear, so a 235 tire will be more square stretch-wise.

i have been looking through here and havent really seen anyone running the size i am looking into. i may be getting a really good deal on work meister s1 wheels. the sizing is kinda out there. they are 18x9.5 +12 (R disc)
18x11 +5 (O disc)
i know i would defiantly have to stretch but they are honestly just for shows and stuff. i defiantly know i would have to camber the rear. and my fenders are already rolled. what else would be required to make these fit. it is just a really really good deal and id hate to pass up on it!

thankyou

awesome to know they will fit upfront! did u have to pull the fronts, and what size tir are u running? and i know the rears may be pushing it ecspically with stock fenders, but do u think they would rub on anything or at least fit with more camber
thankyou!

I run 19s though. 235/35/19F
Rolled guards.

Rear, you would probably have to run a bit of camber

Fender pull up front, even more fender pull in the rear. Front spec is close to what I run but on 19's, rear spec is close too by with an 11" +5 you'll need some major camber to fit under stock fenders (even after a roll and pull)... Unless you flare the rear.

Would 18x8 +30 and 18x9 +42 work?

couple questions....

what is the widest rim & tire size you can fit, on coilovers, in the front & back without fender mods?

and i'm looking at some wheels now, but will a rear 19x9.5 rim with a +55 offset work without rubbing or issues?

I would like to get a pair of rims size 18X10 +25 off set all the way around on stock suspension and stock ride height, I read +38 is the lowest we can go, so what wld I need to do in order for these to fit?

Widest rims and tires are 18x10 and 18x12. See Cherplex's thread: https://www.clublexus.com/forums/sc-...tock-body.html

9.5s +55 will fit, but I'm concerned that you'll hit your springs with that high of an offset on a 9.5" rim

i run that exact size in the back with a 255/40/18 tire, and i had to roll my fenders and do 2 degrees of camber in back to fit them properly. im on supra tt struts and tein springs.

if you keep stock ride height, it will just look stupid. probably wont rub (in back at least) unless you hit a major dip, but it will look 4x4 status

That is very close too the OEM IS350 wheel sizing, which is: (F) 18x8.0 +45 / (R) 18x8.5 +50
Those fit no mods with ample clearance, so you should be fine
