Ok, man I'm soooo pissed at myself. It goes to show that when you think you got everything done right, something can and always goes wrong. So I ordered some Sevas s22 for my IS350, the wheels look great and yes I had to use a 5mm spacer to clear the front brakes with no problem, (so far). Anyways, I decide to order some Kuhmos SPT size: 245/35/20 fronts and 275/30/20 rears and used Tenabe springs (not the GS ones). Well I get my car back from the shop and on the way home I'm fealing that the front tires rub like crazy. I bought the wrong profiles! I should have gotten 245/30/20 instead of the 245/35/20. Well I can't return the tires back to the Tirerack caused I drove home on them and it turns out that Kuhmo does not make any 30 profile tires in 245 or smaller that are 20inch, they only make a 30 profile for the rear 275. What can I do? Should I shell out the money to get a whole new set of different brand tires maybe Falkens 452 or, should I just buy a set of different brand tires for the front only and keeep the other Kuhmos in the back? Would that make that much of a diffenrece? Please help.

 

Find out where its rubbin and see if you can do something about it. Not telling us where its rubbin will make us guess a solution. Do you need to 'roll' the fender, do you need to heat gun the inner fender well shield, is it rubbin against a suspension piece.

More info on the rub, less on 'why'.

 

I would buy new tires and put the "old" ones up for sale in the wheel and tire classifieds.

They pretty much rub everywhere around the outer part of the inside of the fender and on that piece that sticks out on the rear of the bottom fender. Then one that most people have issues with. They rub over bumps, when I turn the tires about 45degrees and when I brake hard.

 

Get new tires and sell these.

 

Doh you got major problems, if your not good at fabrication type mods get new tires.

 

bumpbumpbump!!

 

if you did some searching alot of us would have told you not to run a 245/35 front. the kuhmo SPT doesnt come in 245/30 but it does come in a 225/35 which will clear with the heat gun trick.

 

sorry I can't help you there, but if you need tire let me know. I have a set of 20" falken 452 235x30, 275x30. pm me if interested.

 

just gonna have to take em off and sell em . . .

i am about to get some 20s and im gonna go with toyos in these sizes:

235/30/20 F
275/30/20 R

 

yeah i would go with this route . . .

 

agree....try to post it on www.craigslist.org

 

I wouldn't drive on this anymore than you already have...

You just might damage your Fenders top/side exterior panel & paint if you hit a bump on a turn..

 

Those sizes might technically work, but they will look funny IMO due to the difference in sidewall heights. I think a 235/35 would look much better with a 275/30.

 

id go 225 or 235 in the front and that should help.
