Hello and great to be back with you folks ! Tire pressure has been discussed before but as a safety concern I don't mind relating my recent experience. I ride a 70 mile round trip to school once a week. About 20% twisties and 70% flat out freeway on the very windy Humboldt County coast. Last two trips I noticed the normally rock steady Tdub was getting blown all over the place and just felt dad-gum twitchy! I had 18psi in the rear and 20 in the front, should be ok I thought ? My steering head bearings seemed tight enough, so I figured it must be my worn out Bridgestone front tire. It was a great excuse to the wife for me to get a new Kenda k270, heh heh (see pic). This morning I decided to pump the old tire up to 22psi to see if that would help to avoid a possible high speed tank slapper. Holy cow, a mere 2 pound increase and I've got like a new bike! That old worn out Bridgestone (7500miles) is tracking like the monorail at Disneyland. The moral of the story, go ahead buy new tires but keep them properly inflated.
