Rubbing issue with MPS4’s?

For any of you that are running the MPS4’s in 255/35/19 and 295/30/19 are you having any rubbing issues? Any other issues? Thx

No rubbing that I notice. I will check my wheel liners to make sure though.

We've had this combo for almost 2 years now. The only time it rubbed was at full lock when backing up, and that seems to have gone away as the tire wore down slightly.

Any reason not to go with 245’s in the front?

Then the diameter between the front and rear would be different. 245/35 matches 285/30 while 255/35 matches 295/30 on 19s

Are you running the MPS4’s in the 255/295?

I'm on stock corsas and bought a take off set of corsas as a replacement. For winter, I use Alpine pa4 but also I'm oem 245/285 sizing
I'm about to order the Michelin's after 2 sets of the Corsas...

It's these ones right?

Michelin Pilot Sport 4S
Front 255/35 R19 96Y XL BSW
Rear 295/30 R19 100Y XL BSW


Mine is a 2018 that just had the replacement 2017 height springs installed, so I'm hoping I should have no issues.

That’s the sizing. I have a 2018 and waiting for the springs to arrive at the dealer. I found the PS4’s at Costco for $1400, but I’m waiting to hear if the rears are available. Schwab quoted me around $1650. Hopefully it all works.

This is the answer lol!

I've run 255/35/29 MPSS on the front of my Giulia QV without any rubbing. However, my new set of MPS4S DO rub when backing up just like @JoeCab said.

When I heard the rubbing I got out to look while the wheels were locked to the left...

The tires do touch the rearward felt fender liner, but you only hear it when backing up because of the way the tread is cut. It does rub moving forward when the wheels are locked, you just don't hear it. The tires are also SUPER close to the forward, plastic, vented fender liner, but not rubbing that I can tell.

So just wear them down a bit and you'll be good.

I'm here to tell ya that I notice a considerable difference in grip between the MPSS and MPS4S!! With these MPS4S I can floor it from a stop and it just bites and goes! It helps a bit that my Squadra Massimo tune by @Alfissimo "squeezes" on the power from a stop helping you to move forward vs burn out and fish tale, but still... these tires GRIP!

To be honest, I like them better than the CUP2s I ran on the car.
