Track Experience MP4S?

Powerslide · 06-27-2017, 11:28 AM

Just wondering if anyone has had a chance to do a full day track session with the MP4S? I currently use Bridgestone RE-71R and love them - not sure if MP4S is comparable (assume better than MPSS - but not sure by how much on track). Thanks,

No proof but I'd say the Bridgestone would have more dry grip.

Not that tread wear rating is the end all be all, but the RE-71R has a 200 rating vs the MP4S at 300 so not really in the same category (Tire Rack calls it extreme vs max).

RE-71R are great on track but wear quickly. I know some people have had chunking problems with other Michelin products in the past on track, but hopefully the MP4S fair a bit better. Ultimately the Bridgestone's will be faster but likely wear out faster.

Bump, I'm also curious about this!

The RE-71R are THE street tire right now (they stick like R comps). They are also amazing wet tires as I was told and some ppl are using them as an intermediate tire on track

What track? If you're going to Grattan, you'll be fine. The surface there isn't as grippy as other tracks, so it isn't as hard on brakes and tires.

Edit . . . I misread and thought you were asking if they would make it through a track day. They will, depending on your driving, your alignment, and the track, but they are not comparable to an RE-71R.

RE-71R's are damned near R comp tyres, but are advertised as "extreme" summer tyres. Don't let it fool you, they are sticky and grip hard.

The MPS4S is not comparable at all. It is a street tyre with track capabilities, think of the RE-71R's as the opposite: a track tyre with street capabilities.

I'm currently running my RE-71R's as a street tyre with some track work planned soon. There's loads of information out there though. The gist of it is this: better grip means accelerated wear. Well worth it IMO.

I would say it depends on how hard you run and how hot it is. Speaking from personal experience, I run f255/r285, and they were doing great grip wise. Very communicative and confidence inspiring. That is until the middle of the day when the pace started to improve and the temperatures started to rise (Miami summer heat)... Then they got real greasy, at that point I had a big moment and decided to call it quits. Oh yeah the degradation on the shoulder was pretty bad, the tires were basically brand new so I'm glad I stopped. I thought I could really track it and maybe get 5-6 track days out of them, that was my plan. But after that one time I realized that the tires would be limiting me and that it wasnt going to be cheap going through those PS4S, so I just went ahead and bought a second set of wheels with tires.

RE71R has more grip than P4S and is a better tire for me.

You have to decide what 'better' means to you and your driving style.

noise, trackability, softness, tread life, etc...all attributes that contribute to your perception.

the bottom line is street tires have come a really long way but there are still compromises to be made. i'm excited to see what comes next.
