The Bridgestones are tractor tires IMO, any good dyno shop will align the bike properly, if Bridge/Fire has a concern it is probably due to their own products. The stock tires are general use tires, much better tires out there, like the Metzlers on the SMs. I switched at 4K to Avon Venoms and what a difference in tracking, bikes geometry, overall ride and feel. Cornering is very sweet. The Bridges are very hard tires, but my contension is the dyno shop moreso than the tires themselves, although the Bridges are bottom of the ladder when it comes to tires on the TA. If it was such an issue I would suspect dyno shops would have a big-****** sign posted in this regard. Never heard this one before but suspect others havent either. How paranoid are you?? If mucho, change to a better tire and not worry bout it.
