1990 R 100 GSPD new tire trouble

[chasmrider]

I was wondering if anyone has a suggestion to get the bead seated on my front tire. I replaced the tire, Heidenau K 60 scout 90/90 21, after some wrestling got it on the rim. now I can get it to hold air sort of, but the bead ( which is really stiff on this tire ) won't pop on the rim. I am using lube ( dishsoap and water ) , and have the tire holding pressure, but the air leaks out in about 2 minutes, and you can see the bead hasn't seated. my friend just called and said straight soap and more air pressure, so I guess I will go try that.

The metal part of the tire has to be very clean. Soap will probably work, but there are "professional" liquids that are likely better. It will seat better if you do it out in full sun, if you're so fortunate...things limber up when warm/hot. Also, once you have pushed some amount of overpressure in the tire, try bouncing the tire in the areas that you're having trouble seating...maybe that will help move things around. I'd be cautious about the amount of overpressure...don't know what is too much, but certainly 100 psi is, maybe even 60 psi is.

Old rubber bits on wheel can cause this. I wire brush the wheel.

thanks guys, I will clean the rim better next time. I got it on, used straight soap and full compressor pressure. I think my compressor makes 90- 100 psi, when it popped on it sprayed soap everywhere, good thing I had my safety glasses on. I am going to Alaska next summer, and wanted to know if I could change a tire on the side of the road. I got it changed ok, but I don't see my cycle pump airing up and seating a new tire.

I have a K60 on the back- with a tube
Advice given really helps- especially the tire as warm and limber as it can be. Sometimes you need the pressure- just be as careful as you can as you will probably pass some limits.
