Use high pressure rated tires and new tubes!

This may be stretching the capability of tires rated at around 50 psi or lower.

Also, it may be a idea to use a new inner tube, if one plans to use high
pressure such as 90 psi. (I decided to replace the 10 year old tire on my 24"
racing Miyata. On the morning the UNICON VII marathon was held, I found that the
valve stem had exploded! I had to borrow a unicycle to race, because of the
mistake of using a 10 year old inner tube! Please don’t make the same mistake.)
