tire help

[wupe]

Hi,

I have a set of 4 Goodyear F1 17's. After 20k, the front looks ok(maybe still have another 8~10k), but the rear tires look pretty much wornout. I am thinking to replace only the rear 2 tires at this time with a different brand(Sumitomo HTR3), and eventually replace the front ones when I wear them out in 1 year. Is there any problem with 2 different brands of tires??? This is my daily commute car, I dont track nor ever get wild on this car.

While it is not recommended to mix tire brands or types (ie summer, winter, all season), you certainly can, and people do it all the time. The handling charactaristics/dynamics will likely be different, ie more oversteer or understeer depending on what tire you have where. Personally I wouldn't mix and match, but that's just me.

Like larez2, it is not wise or safe to mix tires front to rear (or side to side for that matter) on any car, no less a high-performance car. Whether or not you track the car, the difference in performance characteristics between the two pair will create some risk for you when driving. All that said, I would recommend you get a set of F1's so that when they, and the front wear out, you can toss them all and get a better set of tires. I have a set of F1's on my Ford GT (2005) and they are legend in the GT community to be absolutely terrible tires. Unfortunately for GT owners, tires of the equivalent specs don't exist so many are forced to replace them with the same ones. Needn't be true for your Porsche.

Go pick up a set of Michelin's. They are by far the best tires. I am referrring to the Pilot Sport PS2's or if you want an all season pick up the Pilot AS Plus tires. Avoid Pirelli, Conitnental's at all costs

Many thanks for all the replies. I will get a set of 4 Sumitomo since they are so cheap with good review from Tirerack.com($79 for the front & $99 for the rear)

Check out the new Dunlop Direzza Z1 Star Spec. Grip is pretty awwesome (similar to Pirelli Corsa's - I had them too), UTOG is a very decent 200 and turn sharpness is great. Best value out there IMO.
