Eclipse 4x4 runs 18x8.5 rims. Dunno if thats what you mean.

 

[o0-TaLoNbOy-00o]

yes but whaut about the offset!

235/40/18 will work... just need to roll the rear fenders wells. . . .

45 might be much without rolling your fenders! You can run up to 8.5 with the right offset and not rolling your fenders. +35

im going to be running 18x8 HP evo wheels with kumho escta spt tires 235/40s. . .

a friend of mine also is running 18x8 235/40 setup on his gsx. had to roll rear fenders and is good to go. he is also running koni red/eibach sportline suspension setup

With a +35 you should be good to go with a 235! There's always playing with the camber to get some bigger rubber on there...

ok ok..so wut if i get like a rim with a 30mm offset..does than mean i can just get a 10mm spacer to make it a 40mm offset?

Apparently no one else around here is either. And no one reads any of the stuff in the tech articles and FAQ and hundreds of posts on wheel and tire fitment...

In case anyone read and believed the post above explaining offset, please forget it. It was completely wrong. A better term for offset is the German term 'Einpresstiefe' (ET)which translates as 'Insertion Depth.' The higher the number, the more into the fender the tire will be positioned. As the number gets higher, you risk rubbing the tire on the rear steering knuckle that passed over the tire at about a 45° angle. As the offset number gets lower, and the tire gets wider, the outside edge of the tire may not clear the fender edge and the flange inside the fender. "Rolling" the fenders bends the flange out of the way and keeps it from cutting into the tire.

That said, the wheel will fit, as will almost any wheel with the right lug spacing. But no can say for sure that the tires will fit until they know the size and brand of tire, what type of suspension you will use, how much lower the ride height is, whether or not your fenders will be rolled, and if you have adjusted rear camber. Using narrower tires, with a more conservative fit, not all of these will be critical.

Now everyone please read the site rules on posting "hearsay."

YOU ARE GOD!!..ALL HALE WRET!!
i knew some of that stuff didnt make sence ### i looked on that offset calcutor website and it showed a gsx with an offset of like 25 or something and the wheel where stickin way out passed the fender!

Okay. The wheels you propose would fit 225/40/18's without much trouble. The high offset and the conservative tire width would probably keep the outside edges away from the rear fender flanges. I think 235's will also fit although it will be very close on the inside near the knuckle and closer to the fender flange as well.

Now, when you lower your vehicle over wide tires, obviously the tire gets closer to the fenders, but lowering also creates negative camber (tops of the wheels slanted in). When you correct this, the tires get even closer to the fender edges and flanges.

Here are a couple of my cruded drawings:

NO hearsay here, trial and error before all of you tech articles.

ok now one more question...if i get a 235/40/18 will i have to roll my rear fenders?...wut about the front fenders?..

 

[wret]

The 235's with that high offset will be pretty close to the flange in the rear. Too close for me to call. Just roll it and be done with it. It's not that hard. There is no flange in the front.

 

[o0-TaLoNbOy-00o]

hmm ok..well wut about a spacer to lower the offset?
