Re MATKAT post "Entry sent "
--------------------------------------------------------------------------------
Just mailed my entry for the Cambrian, the Airhead team with Dennis and his mate !!
Does anyone have any tyre recommendation for this event. Has to be a full road legal E marked tyre, and you cannot use Michelin AC10 or road legal motocross tyre??
Cheers

Airhead Tyres for the Cambrian
As far as tyres go for riding an Airhead in the Cambrian Rally – back in the 90’s we were limited to Dual Sport tyres for the trail bike classes. I used Pirelli MT 21 tyres on the G/S. Front 90/90x21 and rear 120/80x18
Since around 2001 WTRA introduced the use of FIM tyres for the big twins and as a result I started using Michelins (t 66s I think). Front 90/90x18 and rear 140/80x18
I normally run with one security bolt on the front wheel and two security bolts on the back wheel, and have my tyre pressures at 19 front and 18 rear. I keep these tyre pressures for the sighting lap and then make a judgement as to whether to drop them lower after I have seen the terrain
I know that many people run a lot lower pressures than that, but I am always wary of compression punctures and dings on the wheel. It is easier to loft your front wheel with the smaller machines if you are heading for a rock step. The G/S tends to hit it and then bounce up/over it.
As far as competition use goes – for a pair of new tyres - I get 2 days use from the back and four days use for the front and then I bin them.
Hope this helps
