Mixed PSS and PS2 on Front Wheels

DailyDriver · 06-10-2014, 09:06 PM

I've been running a full set of Michelin Pilot Super Sport tires, which replaced the original factory Pilot Sport PS2s. I'm a few thousand miles away from replacing them with a new set of PSS and just got a puncture on the left front tire. Luckily, I got a replacement tire that was covered under my wheel/tire insurance so I will only need to buy three new tires instead of four. However, the replacement tire was a PS2 and now I am running mixed PSS (right) and PS2 (left) on the front wheels.

I presume there shouldn't be a problem with this setup since the tread pattern is so similar, but what are your thoughts? Also, when I replace the remaining three tires with new PSS, should I keep the PS2 with only a few thousand miles on it or just opt for four new PSS for uniformity in traction and wear?

Appreciate your thoughts.

michelin doesn't recommend using mixed PS2/PSS setup.. especially in the wet. I had the PS2f/PSS rear setup before my full PSS setup and I felt a different.

Thanks for the feedback. Luckily I don't have to worry about the rain in Los Angeles, but I'm going to just get four new PSS when it comes time. Shame to get rid of a barely worn PS2, but I agree with you.

This is not an optimal setup. The tires are quite different. It may not be a problem for sedate daily driving but it will handle strangely, especially in the wet. Be careful and replace them with a matched set ASAP

You can sell the new PS2 on the forum for around a couple hundred bucks. Tell the tire shop you will keep the PS2

Sound advice...

I have run:
full sets of PS2
PS2 front PSS rear
Full set of PSS.
My favourite was the PS2 front and PSS rear...with a few extra psi in the front PS2s it gave a much sharper turn in - even if ultimately the front PS2s were giving less grip, the benefit of the sharper turn in made it feel like it had a better balance....at least for me.
Having a different tyre on the same axle is definitely not recommended.
If I was going for a new set of PSS I would probably chose the new M3/4 sizes 255/35/19 and 275/35/19.

Another reason you probably don't want mixed tires in the same axle is because they were not purchased new together and did not wear at the same rate. One wheel will be spinning faster than the other. It'll cause a pull towards one side.

If price is a concern, I'd rather recommend a new set of cheaper tires
