265/35 Rear with 265/30 Front

Would it be crazy to try a 265/35 rear with 265/30 front?

I've had the Yoko AD08 265/30 295/30 setup on my car for the past year which I've been really happy with. Last week I needed to replace the rears and I decided to give the Michelin PSS a try. Once they were installed I noticed they were even bigger than the AD08s. They're rubbing more than the AD08s did and visually they're just a little too big for my taste. I really wish they offered a 285/30 PSS.

I was thinking about trading in the 295/30 rears for a set of 265/35s and running them with the 265/30 fronts already on there for a while. It would be more or less a square setup and it's 3 pounds lighter per tire. Has anyone else tried this? I couldn't find anyone who has.

Going down 3 width levels is a bit extreme if you are just trying to stop rubbing.

Have you considered just dropping to a 285 rear?

I wish the PSS came in a 285/30 but it doesn't and the diameter of the 275/35 is a little big for my liking.

Yep. Stock ZCP wheels and springs.

The rear wouldn't be an issue as that fitment would work.

You'd have a square setup but I'm not sure how much overall benefit you'd get from it other than the weight loss

Is that on the stock ZCP wheels? I'd actually like to give a 275/30/19 square setup a try but I've only seen it done with the front ZCP wheels replaced with rear ZCP wheels.

Here's another thought. 265/30 front and 275/30 rear.

With the 275/30 rear it's about 2.5% smaller so it won't throw off the mileage or speedo too much. It would be a little wider and a little more torquey than the stock size and the 295/30, wouldn't it?

Why would you run a 275/30? I run a 275/35 and its perfect. And I'm dropped with no rubbing

I wouldn't do the same width and different profiles front and rear, then you can't rotate. It would be a bummer to have 265 front and rear and not be able to rotate. I run 295/30/19 AD08 on KW CS with the tire about flush with the fender and have no rubbing. If I was in your situation I'd switch to a different tire that is offered in 285/30 or 295/30 that fits, it would be disappointing to me to downsize that much.

I'm still on my original Pirellis from the factory on my E92 ZCP but am considering switching to a 275 front/295 rear PSS setup come Spring. What about the width of the tires do you dislike, aside from the rubbing?

I guess that's exactly what I'm asking. With the tread width being the same is there an advantage to running a tire that's 1.1% taller than stock vs 2.7% shorter than stock?

One advantage of going smaller is the 30 tire is 1.7lbs lighter than the 35 tire. The 30 is 3.8% smaller than the 35 and is able to put that much more force to the ground.

Since I'm running the stock ZCP wheels I can't rotate them anyway. I was running the AD08 295/30 rear which I liked a lot but the tread life wasn't great. They were bald in under a year so I wanted to try the PSS. Based on what I read they're almost as good as the AD08s but have a much better tread life.

The rubbing is definitely the biggest issue. They don't rub much during normal driving but as the "fun" picks up or going over a dip mid turn it rubs good. I'm just concerned it's going to rub a lot at the track. I'm not sure what it's rubbing on but if it's a panel clip that's probably not good. Maybe someone that has run the 295/30 PSS can chime in.

Aside from the rubbing it's just visually a little too big for my taste. The AD08s were perfect in the same size. The PSS tires bulge over the rim a lot more and just look bigger. Aesthetically the AD08s looked better to me. If you must have a 295 they're the way to go.

Screw it. I ordered the 275/30 tires for the back. We'll see how it goes.
