Mountain Bike tyre PSI on road?

[Tom Oglesby]

Hey guys, on my tyres it says 30-65 PSI. And basically I'm a bit worried that if I take it up to 65 PSI for road use the tyre will burst if I hit a kerb or something (I'm a big guy), is that something that the manufacturers would have taken into account or should I just take it up to 60 to be on the safe side?

Cheers.

It's unlikely the tyre will burst if you pump it up to 65 psi. The manufacturers will have factored in a good safety margin before printing the pressure advice on the tyre wall!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Depends on the tyre, my mtb can run at 80 psi but as keith says your tyre will not burst as long as you do not go mad and try to pump them up to much above the max pressure.
Road bikes run thinner tyres at over 100 psi so your not going to go boom , why would you run into the kerb though ?

65 will be fine. But as above I would avoid the kerbs. You're likely to damage the rim as well as the tyre if you overdo it.

Why would anyone hit a kerb?

Getting out the way of a cold multi-ton death? It was just an example of something that to me would be a big enough impact to be of concern, not something that I'll be deliberately aiming for. Cheers guys, was just a bit worried that's all.

Ahh i thought you were kerb jumping
How far from the kerb do you ride to start with ? at least a couple of foot is recommneded so your not riding in the gutter with all the drains and road debris , it also makes vehicles overtake a bit better as they have to around you rather than just breezing past plus gives you somewhere to go if they do squeeze you.

I run mine at 65psi on the road, with me at 15st and sometimes a backpack up to 35lb as well , no problems

About a metre or so away from the kerb, more if I'm at a junction. Haven't had a "road tax" comment yet though haha

Hey Alan, is 65 PSI your tyres top pressure rating? I assumed that the manufactures would have a safety margin but I didn't want to be testing that because money's extremely tight until I start work on 2nd of Jan.

Yes that`s the max , i`m of the thought that the tyre will have been tested well past that max psi figure by the manufacturers. To be honest mate it`s not something I worry too much about , I just check my tyres for wear and tear and the bike itself each time I wash and lube it.

Righto, cheers mate.

I have mine up to about 65-70 psi when on non-icy roads. The tires are rated at 65, but sometimes my compressors gauge is a bit off and they end up a bit higher.
