Ideal tyre pressure?

Postby roverthehill » Sat Nov 03, 2012 19:14 pm

Hi,
Had a bit of shocker today with 3 falls. Bike didn't seem right - was feeling the bumps more than usual. I pumped up the tyres last week - can't remember what I pumped them up to but I remember it was higher than I normally would.

What would you guys suggest? Typically, I riding muddy trails with a fair few roots...

Between 20 and 45 psi for off road

Depends on the bike, tyres, rider, terrain, riding style. There is no ideal. Currently I have around 25 and 30, but was running 15 and 18 earlier in the week on soft, muddy ground - felt great to me but people kept on expecting them to pinch flat. And I'm chunky.

Around 30 is a typical starting point, some tyres are very crucial on pressures, others less so, my daughters had almsot no grip at all on Nobby Nics at 40psi at Cannock, dropped to 30 and they were much better (then I dropped them to 27 as she weighs less than me!)

You really should be noting pressures at ech ride and making sure you have a pressure that works, go up or down in about 3psi steps to see the changes, lower pressures and you risk a pinch flat unless you ride a fat bike!

cheers guys. haven't fallen for a while so 3 splashes on one ride was a bit odd even for me. I'll try around 30 and see how I go...

Here he goes again....ignore, whatever works for you.....most people just have a grippier (width/compount/pattern) tyre on the front.

You can actually run the front a bit softer because it has less weight on it, generally.

What's the cheapest pump about with a pressure gauge? Mine has never worked so I just chuck anything in the tyres!

It's never worked because you seem to buy and want the cheapest!

Very true. I have a pound shop pump in my bag. That works, just not very well. They also do a guage. So there you are, £2 and you're sorted. Or not.

My Argos one was a complete failure at £5. Buy cheap you buy twice they do say, but not always.

Couldn't be arsed. Should have really! Their website shows the pump as having shocking reviews. They're still selling it though, this was over 2 years ago!
