    Tires for high horsepower cars, what are you running?

    I got 8,000 miles out of my mickey thompsons 305/35/18's. What other options are out there and what are your experiances? I love that I can hook up in 3rd, 2nd if the roads are warm.

    This is a good thread as well to look at as a reference: http://www.bimmerboost.com/showthrea...-and-the-specs.

    This one will be more about E46 M3 setups though. Taza has struggled with traction and you might want to PM him for some suggestions as well.

    MT ET streets, your suspension also plays a huge role in off the line traction.

    Other people eat shit and die.

    A lot of people forget that drag cars are very sensitive to front suspension. For a drag car, you need to find optimal front suspension rebound on your shocks where the wheels come up slower than the actual front end of the car. You dont want the car to try and rotate the entire front end + wheels because you will lose traction before an useful weight transfer occurs.

    You want the front end to lift up while the wheels stay on the groun and progressively attain more and more traction (all this happens in a very short amount of time). So very stiff front springs and shocks will make it difficult for the front end to come up to help weight transfer. At some point after the front end of the car has lifted up high enough to give you the weight transfer, the wheels will slowly start to lift up. The wheels should not be up in the air, that is bad, you are wasting power rotating the car instead of accelerating. You need to have the front wheels just off the ground, a millimeter so that all the weight is on the rear tires with no more needed rotation.

    Just think about weight transfer, you want to get the weight closer to the rear, the only way to do that is progressively because you are limited by friction of tires.

    Also, taller sidewalls help A LOT as does lower tire pressure. All these things combine will help a launch. Just find the optimal setting by experimenting.

    What's wrong with the MT ET streets you are running?

    A high powered RWD car with drag radials in the rain is a recipe for disaster.

    I'm sure some wide Pilot Sport PS2's (305+) would work ok.

    Traction would be worse but they would be better in the rain.

    That is a good suggestion as well.

    What is the goal here? Something that can be used in the rain? Maximum traction? We need something to work with.

    I'm running Micky Thompson's for the summer, looking for a tire that can handle a little rain when I'm caught out in the weather.

    I just had the new Michelin PSS tires put on and i am telling you their sticker and beefier than the ps2. So far i haven't been able to spin like i use to. i can finally use 1st gear properly without worry about traction issues. ( maybe a little but much better than before)

    You are going to have to move from a drag radial then definitely. The Michelin PSS may be a good choice. You just need some high performance street rubber.
