Hi, there!

I am fairly new to cycling and have a question about on-road tyre pressures.

I have an alloy mountain bike with Duro Rugged Sport 26 X 1.95 tyres fitted from the factory.

They are of a nylon compound and have around 2,000 Kilometers on them now, and still look new.

There is a note on the tyres that says 'Inflate to 45 psi'.

This bike was purchased for exercise and I always use it on paved roads.

I have noticed when riding at this pressure that tyre noise is quite loud and when looking down when riding, deformation is also pronounced.

I am not overweight and weigh around 70Kg.

Sorry for the preamble, but I thought the information was necessary if I am to get useful answers.

My question is, can I safely increase that pressure when riding on-road?

I have been experimenting lately and have found that if I increase the pressure to 60 psi, road noise and rolling resistance decrease dramatically.

Am I pushing my luck with these tyres by doing this?

Regards,
Roger

does the tire have a Max pressure listed?

Tom slick or something similar is a good tire if you want quite and less resistance

The only thing mentioned on the tyre is as I said in my original post ' Inflate to 45 psi'.

Yes, this should be no problem. Since you say they make lots of noise, I'll assume they have a knobby tread. Switching them to a narrower, higher pressure, slick tread tire will transform the bike. You should be able to find something similar to the Nashbar Streetwise tire:

which is rated at 90 psi.

Thank for that, Jeff.

Yes, I will eventually buy some road tyres for it, but am reluctant to do so right away, as the factory knobbly tyres are still in perfect condition.

Actually it's a good time to swap to a less aggresive tire for you may want a good knobby tire for an offroad ride someday.
