    Best way to "balance" new tires??

    I have a 2007 2.7 riding Pontenza Bridgestones on 18in CS rims. So far, totally satisfied with the combination -- but DE days are starting to take a toll on the rear tires, especially the right rear (Thurndernill is predominately counterclockwise).

    I live "in the country" in N. Calif and would like to support local businesses, but I have a concern that their wheel balancing equipment won't be adequate for the tires and high speed -- track only, hehe..

    When I questioned a local shop, they said, no problem we have a high speed spin balance system. How "high" is high speed? Oh, we spin 'em up to 40 mph. Suddenly, I'm not so sure about local shops.

    OK... what is the recommended system to balance those 265/40's ??
    I did do a search and didn't see anything that applied to this.

    Spinning is good - and most places have "spinning" balancing... what you want to ask for is called "road force" balancing... this simulates the tire actually running on the road while it spins... not everyone has it, and they either do have it, or don't, there's no in-between. there are a few manufacturers that make the equipment, most of the ones I've seen are Hunter 9000/9500icon systems.

    Thanks beez... the local guy mentioned "road force" balancing... but being somewhat rural out here, he said that it was expensive and not needed... I was a bit wary that simply spinning at 40 mph was adequate.

    So... how common is road force balancing?? Do the dealers routinely have this capability?

    I believe all Porsche dealers are required to have it. Many high-end tire shops, and some indy repair shops. I get mine done here in LV by a MB/BMW indy repair shop called German Motors - they have it.

    I think road force balancing, with proper equipment, is truly superior to the 'old' ways, especially with tires getting larger and heavier. I recently had that done on my track wheel/tires and watched the process with the technician at Curry's in Dulles, VA.

    The best part of it was that the machine, even at very slow speeds, identified imperfections of the tire and the wheel, then suggested the exact mounting points matching tire's lowest weight section with the wheel's heaviest. After that it showed, graphically, exactly where to put specific balance weights. The results are execellent.

    thanks ... sounds like "road force" balancing is the way to go.
    Anyone in Zone 7 have any recommendations on tire shops that have the equipment. ???

    PS... I called my dealer and was pretty amazed that the guy on the phone didn't know that 235/40 was the tire size for the front and claimed that they were not available. Maybe he was a new trainee, but it sort of put me off from the dealer. I may try again and demand to talk to someone who actually knows tires.. I can check that this dealer has the road force balancing equipment.
