I run these on the street, so if anyone else does too, you should read this.

For those, like me, who didn't know...MSPC = Michelin Pilot Sport Cup

 

thanks! I haven't seen that forum before, and it was a good/relevant thread for me! again thanks!

 

I don't understand. Are BOTH available from Michelin suppliers, or is the n-spec only available as OE on the GT3? If you order MPSCs, do you have to now specify which one you want?

 

it's GT3 only, but of course you can buy it and put it on other cars. it's 19" only though 235 fronts and 295 rears if i remember correctly. both are available from michelin suppliers. check out tirerack.com

 

The new MSPC's should be available soon to everyone. They would have been a better choice for me had I known they were diffrent, as I do most of my driving on the street. Although, 19 inch Dymag wheels with these tires sound VEEEEEEEERY interesting.

Also see this if you have these tires....

Well that's what I thought when I first read that linked thread. So unless you are using 19" 235 or 305 tires, the MPSCs you order will be the original style. At least that is how I am reading into this.

I used the MPSCs for a couple years before switching over to RA1s last season. For the additional $400 per set, I don't see the benefit of running the MPSCs. Just my personal experience/opinion.

 

If you go into those links and then read some of the relevant articles re shaving and cycling it's interesting how it's possible to extend the life of your tyres by shaving them when you would think the opposite?
