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.

Anyone?

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.

Running 19's right?

[SlamMan]

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

I'm running 275/30/19 front and 275/35/19 rear.

[SlamMan]

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.

0h sorry it was on 19x10 wheels

[SlamMan]

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