I am running Continental Contacts 26 x 1.75 (the 900 gram flat resistant ones) and both have single flat "spots". What is up? I have deflated and remounted several times to no avail. I have also tried pressures from 30 - 80 psi, and the flat spot remains. I normally run about 45 psi because these tires are so unforgiving at higher pressure.
Oh yeah, and my wheels are true and not the cause of the flat spots.
Are these tires just crap, or am I unable to mount a tire? I've never had this problem with any other tires. The unbalancedness is definitely noticeable when riding.
I would search the forum, but the function is not working for me...
