e36 M3 with 265/35-18 Yok Neova's in STU

OK, I would not have believed it but here is a pic.

Yeah, BUT they are too tall IMO. I'm confident we could get them under there too, but I'm not buying $300 tires for a STREET TIRE class. I'll go run another class before then. Or buy an AWD car where I can't spend that on 245s.

I weighed my Falken, it was 25 pounds. You'll have to bring them over and we can really weigh them plus we can compare REAL tread width. MFG data is a joke.

Paul, do you think you'll need to shift to third a lot more often with the shorter tire? Or do you think the reduced cg of the car will make up for it, in a matter of speaking?

Ok, sounds good.

I go from 62mph to 60mph at the rev limiter (7500rpm). My goal wasn't lowering the cg, although it will happen some tiny bit. I wanted a shorter sidewall and increased tread width. Hoping to improve max cornering grip and steering response. Hopefully gearing change won't be too hard of an impact on slower coarses, on faster courses where I would have to shift anyhow, it will help.

As it is now, I can feel the difference between my old race tires (25.6") and my street tires (25.0"). So the even shorter Yok (24.7") should feel like it pulls harder.

There was an E36 running in DSP last year with 18x9s and 265X35s with fender rolling. No issues. Was still slower than Teucci.

And there was one running heavy 18x10's with 285/30's without flaring. It was pretty maxed out, however, and had some pretty wrinkled up fenders. Looked great from 10' away, though!

I always wondered about autoxing with your sunroof open...

Re: e36 M3 with 265/35-18 Yok Neova's in STU

What if you ran with your sunroof fully retracted? That weight would be farther back on the car...?

Re: e36 M3 with 265/35-18 Yok Neova's in STU

the pictures of the M3 seem to be gone. after doing some searching I saw a picture of a white M3 with red numbers. is this the car or were there better up close shots of the car?

Re: e36 M3 with 265/35-18 Yok Neova's in STU

Any more pics of these? Would 265/35-18 Bridgestone RE-01R on 18x9 wheels fit on my STX E36 328is?

I am trying to decide to get a set of these, or stick to 17x9 with 255/40-17.

I am running 245/40-17 now on 17x8 wheels, and wondering if a taller tire would help, as we banged the rev limiter 3 times on the course last weekend. I figured it might be nice to just have 2 of the taller 18" tires around for courses that require more gearing.

That's an 18x9 and 255/35/18. All kinds of room with max-legal-flattened fender lips - those are my street tires.


18x10 and 265/35/18 Bridgestones. Note: these are a good 10mm narrower than the Yokohama "265". They rubbed under bump travel, front and rear. A 265mm Yokohama would likely rub badly, even squeezed onto the STX maximum width 9" wheel...

And then you'd have to wonder "is that extra tire width wasted on a 9" wheel?" I would say YES.


This 18" / 265 set-up worked pretty well for autocrossing, but it was still a compromise (rubbing).

On an 18x9 the same 265's could probably fit the car better... but the tire wouldn't fit the wheels worth a damn.

This is a tough question. The 255/40/17 works well on a 17x9 (D-Force 5 spokes), but better on a 17x9.5 (custom 3-piece wheels). We ran this sized tire on 8.5", 9" and 9.5" and the 9.5" had the best response, wear, etc. The 17x9 was so much cheaper and lighter, though... cast racing wheel vs 3-piece (which tend to be somewhat heavy + expensive). Its hard to argue against the 17x9 and 255 combo...





This 17x9 and 255/40.17 set-up just... worked.

Yea, I am not a fan of running uber tall tires to fix gearing - these tend to handle differently (more sidewall = different spring rate for the tire) plus they are always heavier. And on an E36 a tall tire like a 245/45/17 or 275/40/17 can and usually does rub in several places, when lowered adequately for STU use.

This is the tough call for STX competitors.... 17" and 255mm or 18" and 265mm. I think the width restriction of 9" for STX pretty much dictates using the 17" set-up and the commonly available 255s.

Re: e36 M3 with 265/35-18 Yok Neova's in STU

Any idea of which wheels are lighter? The D-force 17x9 or the new 17x9 MR1-R at TR, weighing in at 16.3lbs each:

I am thinking that 255/40-17 Dunlop Direzza Z1 StarSpec tires would be the way to go for now, as the car came with a set of them in 245/40-17, and I am really impressed with them.

Someone mentioned on Bimmerforums that the MT1-R might be better for clearing aftermarket brake kits.
