Subject: 650c tires I have a p3 with zipp 404 605c's. The tires are rated for about 170 psi. As I am looking for tires, I am finding them, but with a rating for about 120 psig. A friend told me that I should be using the current ones about 120-130 psig. (I am 165 pounds) My question is am I operating at the right pressure? When I buy replacement/spares, should I be looking to replace in kind? Will I lose alot of performance if I don't get the higher rated tire? What other attributes should I be looking for? Any help is appreciated. Sorry for all the questions. |
