Has anyone seen or have put 255 width tires on a lude or somethings bigger than 215.

 

I run 225s and there are people running 235s. IDK about a 255 on a Prelude. I don't know how that would clear at all unless you were running 4x4 suspension.

 

How you get 225 with spacers and flaring the finders or did you have to play with the suspension components? what size rim you running with those.

Chris F attempted 255 Toyos on the front of his car. I think it worked, but the last time he said anything about it he felt it was a bit too much tire for the straights.

I run 235s. Fitment is ok if you watch the offset.

 

The problem would be finding a 255 that has a small enough OD, unless they've started making 255s that are really low profile in a small diameter wheel. The tires that Chris tried were just over 25" OD. A full inch larger OD than stock.

I've run 225/50/15s on 15x7 +40s and 15x8 +40s with no rolling up front and minimal rolling in the rear on my track car. The ride height is fairly low, but I run quite a bit of negative camber (-2.75 up front and -1.75 in the rear). Using the same fender mods, I've run 225/40/17s on 17x8.5 +40s.

Now, I'm trying to fit 245/40/17s on 17x8.5 +40s, but the front will require some aggressive rolling and the rears will require even more aggressive rolling with some rear bumper mods. I've thought about running 245/40/17s up front and 225/45/17s in the rear so I can avoid the fender and bumper mods in the rear.

With 8.5s, it seems that +40 is the highest offset that you can run. The tire and wheel are fairly close to the knuckle with 245s.

 

Nope. Just installed and went.....It was fine even with very little (-) camber. On a locked turn if I hit a bump it would rub ever so slightly.

What do you do with your car that you want to run such a huge tire?
Please tell me this isn't for street use.

I wonder how Chris F would've done with a different final drive...

 

I want to auto-x my lude so with fatter tires I expect more traction to help with cornerin.

 

Running 245 won't require spacers? Are these tire big enough to cause rubbing when turning or is there enough space in the wheel well for a tire that size?

 

I testfitted 17x9 with a 54 offset on a lude's rear before, it gets way too close for a normal sized tire. With a stretched tire and no suspension travel it'd probably work but I definitely would advise against it.

255 in a normal tire with a 17x8 +35, 17x8.5 +40, and 17x9 +45 would be the sizes I'd consider the limits. Don't forget you will need a bit of room for error since alignments don't stay perfect forever. With a beefy 255 tire, the sizes I just mentioned will only be safe for clearing the suspension arms and junk. From what I mocked up, you'd be approximately 1 to 3" out of the fender (depending on camber settings and tire characteristic). So you would need a roll, pull, and flare for the rears just to fit the size. And the bumper tab relocation as well.

The fronts will be similar I think, also needing similar fender work. In the end, I don't think it's worth it when compared to simply running a 225 or 235 tire.

Well, I don't get anywhere near full lock on a track, so I can't really say. I imagine there will be some rubbing when the suspension is compressed a fair bit with a good amount of steering input (like the carousel at TWS), however I'm running 750 lb/in front springs with a Tanabe front bar and I'm planning to run a slightly higher front spring rate if rubbing is an issue.

Here are some pictures from my test fit. Front camber was actually a little out of whack in that picture. With my normal amount of camber, I think the tire will actually fit better. The rear is where the real problems are. I may have to run a 225/45/17 in the rear to get the clearance needed.

Tire is a 245/40/17 Hoosier. Wheel is an RPF01, 17x8.5, +40mm.

 

Ok thanks for the input. Its weird though I'ver heard of people stuffing 255 size tires in a EK and with the prelude being a bigger car you would think that it should be easier or at least more practical but o well. I'd definitely be happy with 235 or 245, now I just have to learn to roll my fenders.

 

Dude, spend a few seasons learning to drive before you try to figure out exotic tires sizes.
I don't care what kind of tires you run.....and if you check the rules, these tire sizes you talk about are illegal(IIRC)(per SCCA rules for Stock or STS) In which case you will end up in DSP or SM and lemme tell you, some 235-245-255s ain't going to help you there, you're going to get killed by those guys. A Max-Modded Prelude isn't competitive any which way you look at it.....

 

I ran 235/40/17 RA-1's on 17x8 +48mm offsets. no real rubbing issues, didn't have to roll any fenders.
