If need, peel off the rim strip and replace w/ the thick Velox cloth ones and take a peek while it's off to see if excess spokes might be an issue.Įdit: I'm currently running some Michlin Pros and they're holding up very well at around 110-115#s. But, unless they shave off the excess that's poking out of the end of the nipple, it can cause issues later.

Wheel builders can cheat by using slightly longer than necessary spokes. Lastly on the wheel, even tho you have rim tape, look for signs that the tape has depressed and is running into spokes that's too long. Plus, it make the braking surface smooth and even so it doesn't tear up your brake pads. I've seen $60+ rims that have had rough joints. What kind of rim is it? Often when I build wheels, I'll take a fine file or sand paper and smooth out the seams (inside and out) if the rim isn't welded and machined. What kind of rim strip are you using, the Velox thick cloth ones or some cheap electrical tape like ones? At 100psi, electrical tape will behave like a balloon. If it's on the rim side, it's your rim strip or seam of the rim. If there are signs of wear on the tire side, then it supports something small on the inside of your tire. Is it on the tire side or rim side? Does it show signs of wear at or near the hole or is it a clean rupture. The other thing is look at the point where your tube is punctured. I'm thinking it might be something on the inside of your tire.tiny wire from cutting the frayed end of your der cable off and it's in your tire, but too small to see. If it doesn't leave anything, then look for tears on the surface of the TP as the invader might not be hooked enough to catch anything.

Sometimes it'll hook something on the inside of the tire casing, leaving a bit of it on something that's too small for you to see. Another trick is to fold up some very soft TP like you're going to wipe your ass, (a wad of cotton will also work sometimes), then run it on the inside of your tire casing. This will cause tire blowouts when the casing is weakened from the rubbing. Jacksonpt, check to see if your brake is coming in contact w/ your tire.
