Tires: tyre mounting pastes, alloy wheel rims, oxidation problems

Question
Is there any recomended mounting paste for tyres fitted to alloy wheel rims ( motorcycle ) as I appear to be getting oxidization from the paste I,ve used causing slight leakage

Answer
Alan,

There are many pastes available for mounting tires (I prefer a liquid called Ru-Glyde), and they are available through any tire equipment supplier.  In the US, Myers Tire Supply is pretty much the "big elephant" in the industry.

But I'm going to guess the problem with the alloy rims has nothing to do with the mounting lube and more to do with the "alloy".  Aluminum rims are known for oxidation problems. I haven't experienced this myself, so I can only report that some folks have solved the problem by clear coating the rim.
