    Considering for rear tires on 10.5"x20 rims.

    Aside from the obvious (load, tread depth, weight) my question is this:

    How/Why does a 295 tire have a tread width of 12" and the 315 have only 11"? These stats are directly copied from Tire Rack site. My goal is a 3 season tire with larger contact patch (for obvious reasons) and looking for better tread wear for street use. Not interested in DRs as this is a daily driver and already have 14K miles on it this year.

    Any input/suggestions appreciated. Thanks.

    Michelin is the cream of the crop.
    Best tires money can buy.

    Thanks. But while that may be true can you explain the why tread width is greater on the 295 than on the 315. I would think the 315 with a 20mm larger width would have a larger tread width as well. Am I missing something here?

    Tread width must be wrong as every other spec the 315 is wider. The 315 has to be wider

    Actually, I flew my dad, my son and myself to Detroit to pick it up and drive it home to NY. He got to drive it then.....once we passed 500 miles. He's not patient when behind the wheel...lol. I still have our 68 Charger as well. Will be my oldest sons car in a few years (he's 15) so my 7 yr old son said..."so I guess this one is mine when I grow up". LOL Told him to slow his roll on that one. I will tell him you said hello.

    The answer to your query is there is no standard between tire companies. Pirelli has several tires labeled 275, and some are wider than others.

    I think it has to be a typo... it would be one thing if you were comparing a Pirelli to a Michelin. But I assume this is Michelin to Michelin... like Chopper said the other specs lead you to the 315's being wider.

    it's not a typo...

    there are 2x different Michelin PSS tires for the same exact size... the two are for two different applications... one's for K1 Ferrari and the other's for K2 Ferrari

    ... there are 7x different tires in the 295 size... all same width (mm), aspect ratio, and diameter, but different speed ratings and probably different applications (at least for the ones with the same speed rating)

    these are the 2x different 315 applications...

    This is the K1 application... $425.21 each
    Michelin Pilot Super Sport

    This is for the K2 application... $403.71 each

    Careful with the 315's for Ferarri. The PZero is 12.6" wide like the Michlelin and that is a bear to fit (rubbing can happen even at 20mm 10.5" wheels) and it really don't work that well. I am smoking mine out in a couple of weeks and will have all new tires in the spring.

    FYI 20 mm 10.5" is the absolute limit for sticking out, some say it may be too much.

    That is the cheapest route, answer is probably yes. Or get really wild, sell the 9.5" fronts, get 10" fronts and use the lower profile Michelin's all around that require at least the 10" width.

    I want to spend additional serious cash on the DS and a couple of suspension upgrades (lower it, front strut brace, front and rear adj members). The 305 on the wider wheel should get some rubber down and improve it along with allowing me to take out a 1/4" spacer I have on my 25 mm backset wheels also. Except for its bad azz looks these 315's are really not working well, except on a real hot day accelerating, even that is a pain, too much torque and they want to hop bad. I even have the big trailing arms and their bushings installed, don't matter. So I would imagine the Michelin's with the Ferarri spec are very similar, those width specs look very similar.
