I used tyreweld once on a tubed tyre. All was well for 600yards til I got to 50 mph when the back wheel overtook the front. It acted as a perfect lubricant and helped slip the bead of the tyre over the rim. Made for an easy tube change later but a very exciting ride. Never again! As it needs air to cure it won't work in a tube.

Stuff the tyre with grass. You can do 20mph and it might just be enough to get you to a main road where . . . you 'phone the RAC!

Sold it?

Yes, I had to sell Thunderbolt, (who is due to be sold again) and it took me over a year to get over it, but I think back on the good times we had and am grateful for our time together.

Yes Dennis, I seem to remember the discussion and working out front and rear load numbers and tyre footprint areas for you, it must have looked very complicated to you. But the conclusion to the discussion was that the RE pressures are for old school 60s tyres with much stiffer sidewalls.

Leon, my interest here in tyre pressures was solely in that the workshop manual from which you have parted had for once given something like the correct tyre pressures. The online available RE pdf Service Manual has too many misprings to be reliable.



Can you remember where you got the Workshop Manual from please?

Of course it looked complicated to me jefrs, we are all as thick as two short planks on here, apart from you of course, you know everything!!!!!!.

Ive always found Michellin inner tubes to be excellent but HD ones are definitely for off road machinery. As for tyre creep it seems that on a bike with the faily low BHP of the Bullet that either the pressure has been way too low (I run my back tyre at 28-30 psi front at 20-23) or as mentioned someone has used detergent or someother inappropriate lubricant to put the tyre on.

What Hagis described is most certainly due to tyre creep. Its not the ultimate power, its the mid range torque which will eventually twists the outer enough to rip the valve out - nothing to do with Michelin HD tubes, they're fine on the road, trail, even hot laps around Donnington (as if!). Tyre creep is very dangerous and can happen with dire consequences (read Graham Ham's wonderful 'Daisy's Diaries Book 2). The best way to give early warning is to run the rear tyre without the threaded collar around the base of the valve. Any misalignment will show up as the valve starts to cant over against the direction of travel. Solution, deflate the tyre, loosen it from the rim and turn the tube gently so the valve is erect once again. Inflate to 34 psi (as per Avon instructions) and ride off into the sunset.

The Avon (US) site gives recommended pressures by drop-down box here http://www.avonmoto.com/fitment-results



Basically 24F/29R for Skidmaster and 27F/29R for Roadrider on RE bikes
