HI
Would 18x9.5 et25 work transend wheels fit my evo 8??

 

Ran this on the calculator for you running a 255/35 tire. Sure they will fit but due to the +25 offset & the 9.5" width, it will require some rear fender work

Looks like rolling the rear fender super flat (paint crack is likely) may get you there w/out having to pull the fender. If the fender is not rolled flat, a mild rear fender pull maybe needed

Also, not familiar w/this wheel so a front spacer maybe needed to clear the caliper

 

This is something I've been trying to get a handle on for the last few weeks. The problem is that the amount of work needed to fit a 255-35-18 tire on a 18 x 9.5 rim varies depending on offset obviously, but there's also an issue with the tires being used and how the manufacturer measures them. I'll use my setup as an example -

I run a 18 x 9.5 +22 AME Tracers on my 9. I originally, when the wheels were first fitted, ran a 255-35 Hankook RS-3. To fit this setup no work was needed up front, bar a little liner massaging with a heat gun, at the rear I had the guards rolled and I relocated the bumper bolts. With these tires and this work done, plus around -2.0 of camber up front and around -1.5 at the rear, I had no rubbing issues at all.

The Hankook's in this 255 size on a 9.5" rim had a little bit of a "stance" look about them, not a lot, but the sidewalls weren't square. The next set of tires I had fitted up were a set of Federal RS-RR's in a 245-35. I went with this size because I'd read that Federal's are wide for they're size. The 245-35 Federal was roughly the same size as the 255-35 Hankook , and again, no rubbing anywhere.

So I needed new tires again recently and decided to go with the Hankook's RS-3's (just couldn't cope with the noise the Federal's make). Unfortunately there were none available in the 255-35-18 size, so I decided to go with a Yokohama AD08R in the 255-35-18 size. Now the fun starts, these tires rubbed everywhere, over every bump, around every corner. I started trying to stop this by grinding the rear guards away where the rolling stopped (at 3 o'clock and 9 o'clock on the guard when facing). The front also needed grinding along the lip under the guard, but being aluminium, this was a little bit tricker and involved doing little grinds, going for a drive, having another grind, going for another drive etc. I also needed to do some major massaging of the liners, especially under the lip of the guard at the top where it kinda bulges out directly behind the lip. I managed to sort the rears fairly easily, but no matter how much grinding and such I did up front I still had rubbing, especially on fast, tight, corners. I eventually went to my wheel alignment guy and had him take my camber to -3.0 at the front (and -2.2 at the rear just to keep things balanced). Even after this I had the tire rub the guards up front, so I fired the weapon of last resort, and did the Evo Dave Fender mod, and finally, after weeks of mucking around, I've got a car with tires that don't slowly get sliced up by its guards.

So what's the point of all this? When you're pushing tire fitment to a big degree even the difference between tire brands, and the way a manufacturer measures their tires width, is the difference between having a tire, and wheel combo, that fits up easily and one that's a complete pain to make work.
​​​​​To make some sense of this I'm attempting to get some actual widths together for different brands (as opposed to the size given by the manufacturer), just so someone wanting a Yokohama tire in a 255-35-18 , as an example, knows that it's actually 260mm across at its widest when fitted to a 9.5" rim with 38psi in it. This is the link to the Facebook page with the post on it.

The problem youre experiencing all centers around the +22 offset & the 9.5" width. Most of us who track our cars would have steered you away from this low offset. Even the +25 that you are interested in, while doable, is still on the very aggressive side in regards to offset

The +22 is doable, but a rear fender pull is likely needed in combination to the roll & bumper bolt re-location that you havr done

Let me share this pic w/you. This is my car fitted w/a 17x9 +29 running 275/40's. This is the type of clearance needed (roll, pull, bumper bolt performed). The -2.2 rear camber is beyond the norm & is a performance negative
