I've done a lot of research, so this post will probably end up being a little redundant, but I'm having issues. Trying to change tires to the Nexen 621 that I bought from Tireeasy last season and never got around to putting on. We've been trying all day to get this thing to pop, and can't. We've used lube, soapy water, pressure up to 115psi, leaving it at 115 in the sun, more lube, more soapy water... nothing. Any advice? It's the first tire change on this bike, and the rim looks perfect, so there is no gunk to sand down or anything. It looks like it wants to go... it just... isn't. I'd really like to get this done today. My buddy wants to leave it at 115 overnight, and if it doesn't go, told me to just order a MC tire. NEVER!!!!!

Thanks for any advice!

I had the same trouble with my Potenza. I took the tire back off cleaned wheel and tire off really good then applied vasoline
(a lot) on the rim and the bead ten at 120 lbs it POPED. I now have about 700 miles in it .

Finally got it earlier this week. Guy in the auto shop at my store hooked it up direct to the air hose using an adapter so that he wouldn't have to stand next to it, and did it without the core in the valve stem. The guy helping finally got around to putting it on the scoot last night. So far I've only ridden about 3 miles with it, but it is way smoother than my stock battleaxe. There is slightly more resistance into leaning, but nothing that isn't manageable. I'm gonna let it scrub in awhile before I start seeing how far over I can comfortably lean. Thanks all!

1) Inner safety bead - polish, polish, polish. Don't grind or file, just polish. Dremal tool and something like Flitz should work.
2) Tire snot. Very slippery stuff sold at places like NAPA. Tire Snot is an old name but counter person will probably know.
3) Use the tire snot on tire rim before you put it on rim. Also, put tire snot on rim on both sides of inner safety bead.
4) Now that summer is here, leave tire out in sun before you start. Let it warm up while you are pulling wheel, dismounting old tire, etc.
5) Go for it. Pump it up, if it doesn't seat, deflate and do it again. You may have to do it a handful of times.
and You may still have to go to or close to 100psi.

It has worked for me several times.

+1 I've read a lot of these posts. The only issue I see with leaving it in the sun would be if the lubricant you use evaporated. But time and the lube are your friends.
