I know there are quite a few people running replacement tires or new tire and wheel setups so I have a few questions. My last two sets of tires have been 225/45/18 Kumho Ecsta SPT's, but I might be getting some new wheels before too long. I just wanted to see if anyone is running 235/40's or 235/45's. I have only found one tire in the the 235/40 size that will fit a 7.5 inch wide wheel, does anyone know of any others?

 

I know Denny has 235/40's on his stockers with a set of Falken's. I don't know if those are the tires you are talking about, but here:

I have the tires in my sig, BFG 235/40/18 on the stock rims, look great and fit fine. Noticible increase in traction over the 225s I had before.

 

yea i wonder how some good 235/40's and a ETD would improve traction!!

cuz right now i have BALD stock 225's and no ETD lol

 

Can you run the 235's with the Eibach lowering springs??

 

stock pirellis are 215's bro

thanks man that helps alot!

 

Bump for an excellent question before I go and spend $750 on tires.

 

How many miles were you getting out of the SPTs? And how were you driving on them? Just wondering, since I have the same tires.

 

keep this going im looking for some 235/40/18's here in about a month, right now im looking at the toyo proxes t1r and the falken fk-452

 

Fo sheezy need this info since im lowered too!

 

i know that with the offset of my rims both 215's and 225's rubbed with lowering springs. this is in large part due to the offset. it's off and the wheels sit wide. I'm going back to the stockers here soon and might get 235's. Badmunky had problems with the front wheels rubbing on the inside of the fender. those were with BFG's, and he wasn't lowered.

 

I've got 135/40r18s on stock wheels, no rub at all.

 

If you want a good answer you should say which springs the Pro or Sportlines.

You have some skinny ass tires my friend! I know what you meant!

 

haha thanks bro i meant 215's woopps

 

So what tires have been prooven to be good for stock wheels and go 235/40?

Is there a big differenve in tractions between 215 and 225?
