Tyre Suggestions?

Recommended Posts

my rear tyres (conti) have turned ito slicks in only 18k km. i must admit this has supprised me a bit. but ok. i now need some new ones..they are completly smooth in the middle, the outsides have about 1mm. this indicates a too high tyre pressure (3 bar)... the front are not looking so good either and i have a lot of noise which i suspect to be balancing problems which no-one seems to be able to solve. so ill change all 4.... would like to hear what suggestions some of you might have as to the best combination..i have the 18" turbo look wheels and a "sporty" driving style. ;)

cheers and happy christmas

kelvin

ps. while im at it im going to change the brake discs (rotors) and pads awell...i hope that gets rid of the noise i have been experiencing.

this is going to be expensive :(

General opinions seem to rate the Michelin PS Rib and PS2 very highly........

Your tire wear does not necessarily indicate your pressure is wrong at all. Sounds more like you are running a close to neutral camber in the rear. An allignment set within Porsche' specs would MANDATE that the tires wear more on the inside half when driven on the street or highway. Running excessively high tire pressure on this setup would still wear the inside of the tires first. When alignment is with specs, and you drive on the street and/or highway, you will NEVER, EVER wear the outside half of the rear tires before wearing down to the belts on the inside half of the tires.

Running a neutral camber is not a good idea as it will greatly reduce the handling of the car. Your tires will last longer, but you will not be able to drive as aggressively as you could with a proper allignment. You may also expereince backend wobble in the rain. Many owners who only drive the car around town or long trips reduce the camber settings to save on tires. I would NOT recommend going to a camber of less than the minimum spec. I run at the low end of the spec and it still handles fine on the street and I get a little more mileage out of the rear tires.

I suggest you take the car to an allignment shop of your choice and have them throw it on the machine. Have them print out the current settings so you can see what they are. Compare them to what is recommended and have them dial the rear camber down to the minumum.

The Bridgestone Petenza's are a good tire in dry or wet. If you do not track the car, get the stock pads and rotors (if you need rotors). They make no noise.
