    Re: New Tires

    I'm in the same boat, just turning 4,000 miles today, and my tires are at about 45-50% tread remaining on the rear. I'm going to rotate this weekend.

    I've been thinking, though, what about 255/45/18 when I do replace them (rear only). Anybody see any problem with this? What I was thinking is having a "track set" with 245 front and 255 rear and my "street set" with something less sticky with 245 all around. I've already built my little inserts for the spare tire compartment to hold the tire goop and inflater, along with a single Kicker 8sl5...but that's another story (sorry, no photos yet).

    In other words, the run flat thing isn't entirely important to me right now. I'd just like some great handling and maybe about 10,000 miles per set of tires (yes, I've practiced wheel hop and am sure this and 2nd gear are why my tires are missing their life span - not to mention the tireshredding I did during AutoX last weekend).

    So, again, any reason we can't go 255/45/18 on the stock wheels in the rear?

    Shouldn't be a problem mixing 245 and 255... that's within the limits of the StabiliTrak (though i'm basing this on Z06 algorithms, haven't tried it myself on a V) - it'll change when it kicks in just a little.

    I assume you dont mean mixing tire brands, i.e. stock 245 and some other 255


    Update: Opps, my comments above are for 255/45/18... which is 0.3" taller.

    Yeah, you got me there , but I still think 8.5" is too small for a 275/40 tire.

    255/40R18 is about .6" shorter than the factory 245/45R18s. It will fit, but I think you might notice the size difference...That is unless you run it all the way around, which you could do, or even run 225/45 up front (though 8.5" is really too wide for a 225/45 tire)...

    I'm not sure if 255/40/18 will work so well... first the rear will be smaller than your fronts.

    And the limit for the traction/handling system on the Z06 is 0.7" - difference in diameter between front and rear tires, relative to stock - before the system shorts throwing code. (i.e. rear can be 0.7" taller than stock front; or increase front diameter 0.3", then you can increase rear by 1", etc.) - not considering how much the speedo will be off here.
    So with 255/40, you'll be pretty close to the limit.

    Re: New Tires

    Clinton, what about just running cheaper 245/45 tires all the way around?

    Something in a "Ultra high performance" category, not "Max performance". Dont know how much this will hurt handling / traction... of course it wont be like an S03 or Pilot, but compared to the runflats... might not be too bad.

    Dunlop SP8000s & Yokohama AVS ES100 are ~$160/tire... less than half the stockers... and rotate often.


    Trilio, get in touch with CCW... http://www.ccwheel.com/ and ask if they make their *race* wheels for the V, I think they do. Cant touch that wheel for strength and weight ~$450 a wheel.

What you end up doing is pulling the sidewall in and creating a roll effect when cornering. You just will not get a good, reliable seat on the wheel. I've been a wheel and tire fanatic for a long time, and it's not something I would even consider. The handling you lose alone would negate me from doing it.
    No he said a 275 with 9" would fit. New rim.

    Re: New Tires

    Hi all...

    Just an fyi...

    I'm running 255/45-18 all around. I couldn't stand the runflats. Pirelli PZeros.

    I really like them.

    Re: New Tires

    Whoops, that was a typo above. I meant 255/45/18...just wanted to be a touch wider and could live with filling the wheel well up a tad.

    My bad...

    Re: New Tires

    That is the size im going for in the Bridgestones. About 3/8" wider and a hair taller. I should have my wheel by the end of this month. Brushed centers, polished outers.

    Dreamin-


    They rub on the fender skirt. The big black plastic thing. No big deal. Only when I bottom out on something.
