The LBS I bought the used road bike from in April (new to biking then) said to not run higher than 80lbs pressure because the rims I have might not hold the tire on well at higher pressure. Plus I weigh 210lbs and my bike with everything on it for a ride weights 37lbs. The flats are always on the back and usually a "snake bite" flat.
I am now using a different LBS and they said that the tire I had on the back was too small (not even a match with the front tire) and put on a larger tire (same as the front). I tried running 85lbs pressure and both times doing this I had "gun shot" flats...tire coming off the rim and the tube popping like a gunshot. I ride mostly on the mountain roads and sometimes there is vegetation or gravel washed onto the road from storms. Sometimes hard to miss at speed going down hills. I am carrying two tubes and a patch kit... and have gotten fast at the tube change...still a pain.
Might try the thicker rim tape and see if that helps.
Between this and shifting problems I still want a new contemporary bike...just can't afford it.
