Hi

Ive only had my T25 a few weeks now Its a Holdsworth villa. Please,can anyone tell me what the tyre pressures should be.
Thanks
Cath

You must of missed this when you checked the Wiki https://club8090.co.uk/wiki/Wh ... es_-_Tyres" onclick="window.open(this.href);return false;

I did. Thank you for your help Rob.

Should be a sticker inside the door jamb witb the std pressures on. But also depends on what size tyres its got..

Isn't the pressure constant?

I thought tyre size would affect the volume of air, but the tyre pressure would be the same/similar

You'd think so, but consider the pressure you put in cycle tyres then (if you could get them on the same wheels), how it would run if you put exactly the same PSI in tractor tyres.

Or how about this.
A finger can be pressed against a wall without making any lasting impression; however, the same finger pushing a thumbtack can easily damage the wall. Although the force applied to the surface is the same, the thumbtack applies more pressure because the point concentrates that force into a smaller area.

So if the force is the same (weight) and the pressure is the same (Psi), all you do is spread the weight over a larger area.

or P = F over A

p is the pressure,
F is the normal force,
A is the area of the surface on contact

Ah, you're just being scientific now Kev.

But perfectly described.
