As the first person to attempt to mount a CT on a 2016 Rushmore model, I bought a Goodyear Assurance tire 175/60R16.

Pulled the OEM tire off, which had 11K miles on it and put the CT on. Now I'm having trouble getting it to seat.

I've filled it up to the 40PSI max that the warning says for seating and deflated it several times but one side just won't pop out to the edge of the rim. I've applied tire mounting lubricant to the edge of the tire as well as in the rim. I've tried to use a cinch strap to tighten the tire on the rim but the ratchet part causes the tire to buckle in toward the wheel so the tire bead is grossly distorted. I have a heater system blowing hot air on it to maybe soften up the rubber a bit so it will stretch a little better.

Any ideas how to conquer this?

 

Ahhhhhh, I just heard the satisfying sound of the tire seating. Loud pop in the dark on night. Went out to check. Yep, both sides seated, nice and round. Let the air back out and will put some ride on in it tomorrow morning then get it mounted on the bike tomorrow afternoon after work.

 

that is a sound that is both satisfying and a little scary at the same time, at least I know that I jump every time.


What I did on mine was to take some emory cloth and smooth out the beads as best as I could. Don't know if that helped or not, but it did seat with no issues.

 

I don't think that's a good idea to use Emory cloth on the beading surface. There is a product out there that is used for adding a sealing to the bead area. It comes in a can like axle grease. I used it on my 06RG rear wheel because I was having difficulty getting the bead set.

 

When I beaded mine.. it took 90 PSI! the local shop guys were scare shitless...

Some research led me to find, if I can recall correctly, a .2in difference between a motorcycle wheel size and the car tire, hence more difficulty beading. Glad it went on ok!

 

I don't think I would run it up to 90lbs. Just needs more lube.

 

60-70 psi no big deal but 90 is pushing it.


Emory cloth is not a issue on the bead surface of a rim I have change thousands of Harley tires and the older ones are caked with old rubber and we need to clean all the off so the new tire will bead and seal so we use a nylon disc in a die grinder and polish the beads up never a problem doing it that way in 15 years so I don't see emory cloth doing any damage either
