View Full Version : 215/40/17 rubbing issues anyone?

I'm considering buying a set of 17x7" OZ Alleggeritas (37 offset) but am stuck on what tires I'd get. I was wondering how people have made out with 215/40/17's in terms of rubbing. I have a stock suspension, no mods at all. I know some people have put on ZII's in 215/40/17, but what I don't know is have those people experienced some rubbing with those tires? I actually have my eyes on the Kumo Ecsta LE Sport in 215/40/17. They have decent treadwear, are cheap, and have the same Section Width as the ZII's, and are .1" taller than the stock Pirellis. I spoke with a rep from Tire Rack and they recommended 215/35/17's if I wanted a 215, but that negates the extra tire choices I get from going from a 205 to 215.

If rubbing does occur when going to a 215/40/17, I'll probably stick with a 205/40/17.

I'm on the same wheels with the ZII's in 215. I'm lowered on Neu-F springs. I did rub and roll a fender under during an Auto-X event with the suspension fully loaded while hitting a drainage ditch..it was a poor course set up and EVERYONE was rubbing, sparking or catching air on that damn thing. Alas, on stock suspension or with mild drop springs you will be 100% ok for the street or auto-x. With a full 2" drop you won't rub on the street, but may (like I did) under extreme circumstances. The other place you may rub is the wheel wells underneath, but it is mild and no obstructive and once a few edges wear in you are good to go. Again I don't know if that's from extreme auto-x tire deflection or whether it would occur on the street at all... but it is benign regardless.

The Nue-F drop is pretty aggressive, so if you are stock height or even mild drop you will be A-OK:

And yes, you get a lot more traction with the ZII's! And breaking is incredibly powerful and controlled, too:

Good luck and can't wait to see pics!

I am on BFGoodrich g-Force T/A KDW 2 215/40ZR-17 and 5mm spacers on the Abarth 17" wheels. These tires are a little taller than the ZII's.
On stock suspension you should have no problems. I am on BC Coilovers and had to raise them a little from where I was with the stock Pirellis to avoid the tires hitting the plastic fender liners at Autocross events.
It is worth going with 215's.

So the general consensus seems to be that on a stock setup I should have no issues with a 215/40/17. That's what I was hoping to hear! I also was trying to prove this to myself based on Tirerack specs. I assume I'd be most concerned with Section Width and Overall Diameter in terms of tire rubbing? If so, I think the tires are relatively close in those regards once I adjust for measured rim width (approx. 2/10" per .5" of rim width).

Pirelli P Zero 205/40/17
8.1" Section Width, 23.7" Diameter, measured on 6" wheel (8.5" Section Width adjusted)

Kumho Ecsta LE Sport 215/40/17
8.6" Section Width, 23.8" Diameter, measured on a 7.5" wheel (8.4" Section Width adjusted)

Is there anything else I'm missing when looking at tire specs? I know wheels come into play too, and the OZ wheels are 37 offset vs 35 of the factory 17" wheels.


Edit: Wait, I guess my tire knowledge is lacking, because wouldn't that make the Pirelli wider than the Kumho when mounted on a 17x7? Or is that only the section width that would be wider and not the actual tread width being wider?? I'm confused, so I'm going to go to bed and will read this again in the AM with a fresh brain lol.

Okay so I looked at this again and I'm still confused. I thought for every .5" rim width changes the section width by approx. .2". So am I missing something here or maybe the specs listed for the Pirelli are off on Tirerack? I know the ZII's are wider (the above pics make that obvious) but according to my calc they would have .1" less section width than the P Zero.


Edit: Meh who cares. I ordered my wheels/tires tonight! I went with the 215 Kumhos on Red 17" OZ Alleggeritas. Thinking they will pop nicely on my white Abarth with red stripes/caps. I'll get some pics up when they are in.

I am running the same wheels with a 225/45/17. I cannot go full lock, but we do not drive the car on the street much. I had to pull my liners though. You should be fine with that setup.

Got them on. There IS slight rubbing on the back of the front tires. There is a rib of plastic that comes out further than the rest of the wheel well, which is what the tires rub against. I'm thinking it will wear down quickly, or that I could take the rib down slightly myself. Either way, I don't think it will be an issue for long. The wheels really do make the car pop.

Very nice - should improve grip and handling as well.
