At CCR 2006 the Bridgestone tire engineer during the seminar made a recommendation for most bikes as follows:
1. Read the maximum tire pressure and set your pressure to 2# under that
2. Was very nervous about recommending Bridgestone Radials for the K1200 - too fat!!
3. Recommended Bridgestone Bias Ply
4. If you want mileage go with Metzlers - if you want rain handling tires go with Bridgestones.
5. Stated that the BMW K1200LT is the "only" bike with rims that can run either radials or bias ply. No other bike at this time has rims that qualifies to run both type tires. Thus, on other bikes if the bike came with radials you must keep them on the bike and the same holds true for bias ply tires.
6. FWIW - He also stated that riding styles dictate tire wear - period. Riding down south with heavy loads an aggressive rider will certainly wear out a tire before a one up conservative rider up north. Road temperatures and loads develop higher tire temperatures and result in faster wear - all things being equal!
7. Lastly just to keep things in perspective - remember your bike is riding on air pressure not the tires!! This will certainly help you keep focused on proper tire pressure all the time!!
8. Oh and I did ask a loaded question and got an unexpected answer. The question was "Would you ride on a patched tire? - with our hesitation he said yes!! But gave a qualifier: must be away from the side wall, entrance and exit puncture must be clean and away from the cords and use only mushroom style plug patches. New adhesives are self vulcanizing and when properly applied become part of the tire during heat up cycles. If you use the tire patch materials as supplied by BMW this does not qualify and you should only ride on the tire for a limited time. He had examples of tires that showed these plugs allow moisture to get between the layers on the tire (during cool down) and after repeated heating cycles large chunks of tread would come flying off - totally away from the repair site.
9. On last thing (as Steve Jobs would say) - if you have trouble with your tires do not rely on the dealer to know anything or have your best interests. He actually got up on the stage and kneeled down in a praying position and said contact him - he can help, he wants data and he can assist!!
10. So who was this guy - he did not pass out business cards but I looked up technical assistance and looks like you can email the following person to start to get answers: [email protected]
