I havent been able to ride my commuter for the past couple of weeks. I have been riding though so please be gentle. . .

My question is: Before I was able to inflate to 80 psi, and today I was inflating the tires and was only able to get it to 60. The tire specs are 26x1.5 and the tube is 26x1.25-1.75. As stated, I have gotten up to 80 before, no problem, but today I wasnt able to on either the front or the back. One tube is the same, the other tube is new.

I did take the tubes out of the tires, I had to replace a liner, and they stuck to the tire. Could that be why? Maybe they have to be run for a few miles before I can get them up to 80 again?

Its not a huge problem, as long as the tires are firm, I was just wondering why the change.

Thanks
