    Tyre selection and YOU

    Mods, I didn't see a drivetrain/tyre/wheel/suspension section, so I'm posting this here.

    Here's a good article to help folks decide what tyres to go with.

    http://forums.nasioc.com/forums/showthr ... ?t=1538739

    Please note that this is taken from a Tirerack,com review....and Tirerack doesn't sell Toyo (hence no T1R's in the lineup).


    Basically, performance tyres that any Suby owner should be considering, can be broken down into four main categories:

    HPS (High peformance dry)
    UHPS (Ultra High performance summer)
    MPS (Max performance summer)
    EPS (Extreme performance summer)



    The "Summer" basically indicates that the tyres are intended for wet/dry conditions, as opposed to snow and ice (none of which we have down here).

    Typical examples of each category are:

    1) HPS - Sumitomo HTR 200 (treadwear 300-400)
    2) UHPS - Dunlop Direzza DZ101/Potenza RE-750/Kumho Ecsta AST (Treadwear 300 ish)
    3) MPS - Bridgestone Potenza S-03/Potenza RE050/Sumitomo HTR ZII/Toyo Proxes T1R (generally treadwear 220-300...but not always)
    4) EPS - Bridgestone Potenza RE01R/Dunlop Direzza Sport Z1/Yoko Advan A046 (Tread <200)


    Also note that not because a tyre has a certain treadwear rating, means that it's handling is good! Take for example the stock Toyo NP01 tyres on the NZE Corolla....those have a treadwear of 220....but I hardly think that's gonna outhandle some Potenza S-03's!!!!

    I wouldn't.

    Not on a daily driver in our climate....lemme expand a bit.

    I'm sure you guys have seen the "Traction" rating on your tyres right?
    A? AA? etc.

    Take a look at some RE01R's if you can. It :"only" has single A traction!!! But it grips like hell and its an EPS!!! Why then? Simple....RE01R's suck compared to S03's in the wet (trust me I've tried both)...the S-03 has AA traction. The T1R that Navin uses is also a AA traction, which means it has great traction dry and wet. But of course, the RE01R makes mincemeat of both on dry blacktop!

    Most (but not all) EPS tyres are only single A 'cuz they aren't that great in the wet, but awesome in the dry....this is also true for the (old) Sport Z1's.
