Bicycle Mechanics - Tyre pressure

Hi

I know this has been asked before BUT... what is the correct tyre pressure for a road bike. I'm not referring to tubeless.

I bough myself a foot pump with a fancy gauge, manometer or whatever you like to call same.

The max pressure is usually on the tyre sidewall.

Like Michael said...

Most good quality 23c road tires these days have a max pressure of 120 psi. I prefer to go to the max most of the time.

So I went and looked at the tyrewall...


Michelin suggests between 85 and 110psi or 5.8 to 7.5 bar!

FWIW, I have never heard of tubeless tyres for a road bike.

It's a composite type (there's no tube) which you stick to a special rim.

A few months ago, someone posted that Lance Armstrong runs higher pressure in the rear tyre than in the front, because of the load difference. I maintain about a 5-10 PSI differential, keeping both above the minimum and below the maximum listed on the sidewall. That said, note that the rim, rather than the tyre, can be the limiting factor for maximum inflation pressure.

Thanks John

This is the sort of answer I was looking for!

The RTFM sort of reply does my head in. You just want a quick answer, rather than trawelling through pages of manuals or scraping sh*t from tyres and the like.

Happy Easter

I'm sorry, Harry, you lost me on that one. Are you, perhaps, talking about a tubular (boyaux) tyre? If so, they do have tubes. I know, I use tubulars.

I would always put at least 100 psi (6.9 bar). Any less and you run a high risk of pinch flats.

Tout à fait!

They seem to have gone out with the injuns here in Switzerland.
