directional tyres

Post by plugspanner » Fri Jan 11, 2013 8:04 pm

i have just had 4 new recip trials tyres put on my sons sj wheels and as i was leaving them i just mentioned to the fitter to make sure that 2 went on the other way round so as to make them all the same on the vehicle, when a thought occured to me, as with a lot of off roading we seem to spend a lot of time going backwards as well as forwards so why do we not put the rear tyres on the wrong way round?
this might help in getting up out of the sticky situation we find ourselves in!

The main reason for putting them on the "right" way around is so that they clear themselves of mud. When they fill up with mud, going in the "right" direction the mud is forced out of the tyre.

It then scoops up more mud and forces it out of the tyre, in a continual loop that helps you move forwards (a bit like a paddleboat for the mud). Most people don't spend enough time going backwards to make it worthwhile putting tyres on the wrong way around - it's usually a short blip backwards followed by a longer blast forwards.
