tire upgrade question on heavy tubes
Posted: Fri Aug 14, 2009 11:55 am
I was told by a very experienced mechanic that using heavy duty tubes when riding on the freeway a lot will generate high heat compared to normal tubes and increases the chances of failure of the tube. He did not recommend for freeway use for this reason. And he would have made more money selling them too, since they are a lot more expensive.
Any thoughts here? I ride 80/20 highway, dirt and pocked-mark roads.
