Does anyone know how to convert pounds per square inch to atmosphere? A friend of mine, visiting from Italy, asked how many atmospheres my tires hold. Thanks!

multiply psi by .068 to get atmospheres
multiply atmospheres by 14.7 to get psi
A google search of 'convert psi atmospheres' produces this information at a blinding rate of speed.

A simple, but unmathematical answer.

Look at the sidewall of your tire. Chances are part of the answer to your question is there.

Another solution: look at the gauge on your floor pump. Chances are it reads in both psi and atmospheres.

Numeric answer: c. 7-7.5 bars. That's not the max. That's what you'll fill your tires to/ride.
