Tire (tyre) Pressure?

27 posts in this topic

I'm just under 15 stone on michelins. In the dry 6psi front and 4psi rear and recently in the slop I've been running 5psi front and 3psi rear even at hawks nest without any issues. Rough heys quarry last week I dropped just below 3 in the back and was much better

Sounds good dan....so tyre pressure doesnt depend on weight ?

No I wouldn't say so mate unless your a clumsy rider smashing into rocks instead of over them lol.

give it a try and I am positive you'll find the lower pressure a lot better especially this time of year and the rear.

Kids can get away with lower pressure due to their lack of weight, 2psi isn't unusual for 1 that still weighs 40kg or less

I run four and a half psi all conditions in my IRC rear and five and a half psi in the front Michelin on my Beamish Suzuki.

Thanks Jonny. I was just concerned because o my weight on the rear tyre..at 20 stone...Bou n Ragga are guys around 12 stone..im nearly twice their weight. N im not doin sections. Its mainly trail riding with an odd wee play..

Ya I can see why that would seem it would be the case.

But when you consider the force against that rear tire during a big hit for that 12-13 stone Raga or Bou it's got to be at least as much, if not a more, than what the average rider would do to their tire at 20 stone.  

Now because you indicated your doing trail riding I might suggest if your fast on the trail that you run .5 to 1 PSI more on sharp rocky trails but that's opinion and likely not really necessary.

If you are not riding sections, and just using your bike for trail and road riding, then you can increase the pressures quite a lot.   You want to be sure that the tyres do not roll on the rims during high speed corners, especially if cars and lorries may be coming in the opposite direction.   So for road riding in traffic, 12+ psi Front and Rear would be safest, and give a better rolling resistance, and wear.

I don't remember him saying he was going to road ride, if so then yes 5-7 front and 3-5 rear is very low...

It would depend on what tyre they are using, I think the worst tyre I’ve ever used is the x light and never knew what pressure to do on them, are they still around or have they stopped making them? All the modern bikes seem to now come with x11s
