Maximum TIRE(Rubber) fitment thread

[NAIRB]

most people seam to like 255-40-17. 275s are pushing it, but it has been done.

[benz88]

I guess 255-40's and i could still tuck?

[NAIRB]

yea deff, 10s might be a tad of a stretch though, a 9 or 9.5 would be pretty square with a 255.

[benz88]

this is a 255/35/18 on a 10. Which im guessing would be close stretch wise to a 255/40/17 right? Now what offsets should I be looking around? +30?

[NAIRB]

yea it should be the same

get that out of here no stretch!!hahaha for offset it depends do you want lip/concave or flatface honda wheel on there?

Here's my 255/40/17 RT615K on a 9.5 +12 under stock metal. I posted it a few pages back and said it was ~-1* camber. Then I measured again. It's more like -0.5.


I also run a 17x9 +32 and 0* camber on my other car with much less of a roll. If I had a 245/40, it would be 'flush'. I didn't take note of my inner clearance, but it sticks in my mind that I have another inch before the wheel would hit the coilover. Meaning a 17x10 +43 with a proper sized tire should fit inside and have about the same fitment on the fender side.


But I've also never looked at control arm clearance. That could be a problem.

[benz88]

I think I would be more worried about Coilover clearance no? Also can you run 255's up front?

[gsracer]

i run an 18 x 10 +18 up front with a 265 and its pretty close to the coil over.

For a 10" wide wheel all around, my preference is to run -1 offset.

I would love to be able to run 11" wide up front in -13 offset.

LOL, you would need like 65mm overs on the front in order to run a 315 tire on an 11" with -13 offset.

You'd never have problems with understeer again though...

That depends on camber. I loaned out my 17x9s for a Proam event happening today, so these pics are taken with my 18x8.5 +32.

My fingers are up to the second knuckle and have room to spare from the coilover, which seems to be about 3/8" closer to the wheel than the body at this point.


Here's the clearance to the control arm. My fingers are up at the first knuckle and they are squished. I think 2 fingers at the second knuckle would be a more appropriate measurement.


And, with a 17" wheel both of these measurements will be a bit different, as the coilover and control arm are sloped away from the center of the wheel. So maybe a 17x10 +43 wouldn't fit.

I'm down!!!

[benz88]

so a 265 on a 17x10 +20 will clear stock metal, Sweet time to order suspension and wheels.

Absolutely will not clear stock S13 metal. You would need a 10" wheel in the +40 area in order to run a 265. This also depends on if you want to be able to tuck a little tire. I actually ran the same exact wheel you speak of: 10" +20 with a 265 tire.... I had a 25-ish mm pull. This is the setup below:

Note: the 265's I had ran kind of wide. So depending on the tires you choose you may be able to go a couple mm lower on the offset. But now we're really getting specific.

[mikerbike]

Oh, I assumed he meant stock metal, not un-rolled, un-pulled stock metal.

What did you run in the rear? this looks perfect.

I dont mind rolling and pulling the fenders(to an extent). I just meant no Overs in the rear and no FG front overs.

Sorry man, that's definitely NOT max tire fitment. You have 50mm overs... you could/should be running at least 315's out back.

I assumed he did too, which is why I posted mine with pulled metal. As in he wouldn't be able to run what he wanted without pulling it since the setup he wanted was the exact setup I had in the pics.

[ebayDM]

hey guys
I have a quick question
Can i Run a 17x9 +22 with a 235/40 and clear FLT-A2s in the front of an s13 without a spacer?

Thanks

It's for the slowly growing crowd of enthusiasts who are more swayed towards lapping/maximum grip from their car as opposed to drift or looks. Those who own their car and attempt to make their car meet or exceed the performance of modern sports cars, supercars heck even hypercars... whether they just have a street car and do it for personal achievement or race it at the track. Whatever this may be to you if you are someone who likes to see/have/drive on with 255 on an 8.5", 275/285 on a 10", 3xx on a 11"/12", etc... please post.

I'm running 255/275 setup on 18's unlike the rest of the peanut gallery who mostly post on here on 17's throwing out 225/235/245 numbers! Granted I can go as wide as I want but don't shit on me cuz it's not up to your standards.

P.s. you're right, I could be running 3xx IF I wasn't running spacers, it's only round 1 of 1,000... Let it go!

[silviaks2nr]

Then take off the spacers and run wider tires then post again in this thread. I fit 295/30/18 on mild pull on s14 and I think I could pull off a 305 pretty easily.

[Wreckless35]

Sure, will do... when the lovely EXPENSIVE rubbers I'm running burn down. Enough said, STFU!

[SicBastard]

That first post was made in 2007! We've learned a lot about how much tire you can reall stuff under an s-chassis since then. People were questioning IF a 275 could fit in '07, now we're questioning how to get 315s without overfenders.

That being said, 275s are still manly tires, even if the most up-to-date MAX tires guys have moved on.

[Fred Allen Burge]

Life begins at 335/35/17, this is the size I really want for my coupe! I think I could run them on a 12" wheel (?). But at a 12" width what offset is the highest I could run before hitting the coilover? That would help determine how much of a flare would be needed.

i know right......

circa 08 295s 18 x11 +18 stock body, stiff suspension... ill have to look for it but i have a pic of 315s under stock sheet metal around that time
