ALLOY wheel rims are a mixture or content of Aluminum, carbon and other alloys. Earlier the Alloy rims were made of a mixture or Magnesium, but mag-alloy rims were flammable, so in UK they had banned Mag-Alloy rims for racing.
Nowadays in our motorcycles we generally getting alloy wheel rims. Known for less weight, accuracy and efficiency. The charm of spoke wheel is only you can see in Royal Enfield Products. Alloy wheels are very good for tubeless tyres because of sitting position of tyre on the rim. The tyre fits perfectly and accurately on the rim in the periphery which is very much important, improper fitting may cause the bike to start wobbling at the time of riding.
When a tubeless tyre gets punctured you don’t need to remove the tyre from the rim and hence there would be no damage to the rim. I would suggest to never put tyre with tubes on alloy wheels, unless you take care while maintain the tire because otherwise you could be damaging the edges of the rim every time you remove and refit the tire. Those rims are relatively softer than other metals because as we know aluminum is very soft and light material. So on the road if you have flat tyre then the regular puncture fellow would use his screw driver or some sort of Tommy bar which would always damage the rim. Try to only make use of tyre removing machines for removing or changing the tyre.
Alloy rims have got proper seat and edge to fix the tyre rather than conventional spoke wheel rim. And on conventional wheel rims you can’t put tubeless due to spoke holes which will leak all the air.
For alloy rims there is a special tool which is available in the market. It saves the rim edge for sure.
Tubeless Tyre Puncture Removing Kit is available in the market. Always keep it with you.
Yes, Alloy wheels can be repaired. If it’s a total loss then don’t try to repair it, because Rims are a matter of life or death, so don’t play with it.
