Lay the wheel - tire in sun and let it warm up. I use wheel bearing grease. Just enough to moisten rubber. Cleaning tire of all mold flash helps. I use a green scotch bright pad to remove all mold marks. I put a tire on my wheels in March and they have not lost any pressure since. Spoked wheels sealed and tubeless tires.
What did you use to seal the spoked wheels, John?
Had problems mounting Michelin Pilot Activ on the cast wheels of my '81 BMW R100. The rim required a tube.I do use RuGlyde for installation. I did hit 100 psi to get one set seated. Didn't like doing that.Next time around I made a point of really cleaning up the rims. Power wire brush followed with 600 grit wet/dry and finished with Scotch Brite on every surface the bead had to slide over.That set of Michelins popped into place at 50 psi. Smooth up the rims and tires will install easier (and tubeless will seal better).
3M marine sealant. Washed wheel in dishwashing liquid and water. Blew moisture out of nipples. Wiped with alcohol. The application of the sealant takes several days. First application I applied a layer to all the nipples and smoothed out by dipping finger in acetone and smoothing. The sealant "flowed a little. Waited 48 hours and applied a second thin coat spreading out to the edges of the drop area while smoothing with acetone and cleaning any excess with acetone and paper towel. Waited another 48 hours and applied the 3rd layer. Again smoothing with acetone and cleaning with paper towel. I let the wheel sit for 4 days before installing tire. I put the axle in a bench vise horizontally and put the wheel on the axle. I turned the wheel on the axle while applying the sealant. I would spin the wheel while applying to get a good smooth and even finish. The Sealant did not seem to sag. I watch it and would rotate the wheel every couple of hours after first applying. I have heard people make comments about tightening spokes at a later date. Do a spoke tightening and alignment pre sealant. I am not concerned with tightening loose spokes. I will be dead by the time this is required. Air pressure in the tire applies pressure to the sealant against the wheel. Adding to the sealing. Only people that say it will not work are those that have never done it. I changed from steel OEM with tube to aluminium Excel without and lost 10 pounds of weight per wheel. Cleaning the mold marks off the tire helps seal the tire. I have seen tires leak where the mold marks are. Slow leaks, but it was a leak.
Which one? 5200, 4200, or 4000?Larry
