try keeping stock rears. and swap fronts with Michelin PSS.

you'd see the huge change.

also, understeering is actually good for beginner to intermediate drivers as the car is easier to control.

255-35-18 won't fit up front without spacers? Damn, Lexus isn't making it easy to go to a square set up. So, is 245-40-18 as wide as you can go up front without spacers?

The stock wheels sit in quite a bit from the fenders. They arent using a very aggressive offset. You might have been able to fit a 245 on the rim. Might have still needed a 5mm spacer or so though.

This is the space inside the front tire, 245 would be a tight squeeze on stock wheel

True had a blow out on the front, didnt want to put the donut on the front, took the rear off and then went to put it on the front No Bueno

You're not suppose to put the spare on the drive wheels!

Vairox

You want a spare in the back because if it blows it's much better being in the back than the front which can flip your car or cause you to swerve and kill yourself being in the front, I'd put it in the back and drive slow get the issue fixed ASAP

Seems a pretty close fit, you don't have any rubbing issues? did you go with hubcentric wheels or use rings?

jcheng

Nope no rubbing issues at all. Running hubcentric rings.

Thanks, can u post a pic when u get a chance? think I'm gonna go this route... can't find any wheels that will accept the stock tpms though

jcheng

Sure thing.

Since the 245-40-18 tire is taller and narrower than stock rear tire (255-35-18), do you have any problems with the speedometer? I also imagine the ride is a bit softer as well. Is that the case?

i would run 255/35R18 on 18x9, although right now i'm running 225/40R18 on 18x8.75

jcheng

The difference isn't that far off like 1-2mph so it's no biggie.

I'm not dropped so i opted for a slightly higher sidewall to fill in some gap. Running V12 which have soft sidewalls to begin with, they are soft but offer a cush ride and i like the meaty tire look as well.

jcheng

Will 255 fit in the front with a +40 offset? thats cutting it real close! I'm sure someone has done it.

IMO, its too much tire for the front.
