+1 the rear 17" K60 on my DR was a PITA (and yes, the wheel was clean and lubed and everything else). Took 60 psi three or four times before it popped.

I am not looking forward to working on that tire on a ride. In fact, it might be enough to keep me away from the K60 in future.

I had a 17" k60 put on my bike at Adventure Cycleworks in Fairbanks and it had to be ran up to 55psi 3 or 4 times and bounced on the ground but finally set and he does it for a living, so I was worried about doing it on the road with my little Walmart compressor......well I got the chance 2 weeks later on the Dempster. I rode it flat for about 1/2 kilometer up to a road pull out and I had no problem what so ever setting the bead first time with my little compressor. I used Ivory liquid dish soap from the camping kit. The biggest problem was getting the tubes valve stem through the rim I now carry a valve stem fishing tool.

I've run my K60 (on the back of my 950) up to 100 psi to seat the bead.

The thing to remember is that if the tire is rated to 60psi, the manufacturer has tested that tire to well over 180psi. I've run plenty of stubborn tires up as high as my compressor can push (120 or so) with no issues.

Having said that, I use a clip-on chuck (hands-free) and DO NOT stand over the tire while it's seating.

If that tire ever let go, things could get ugly quick! Good advice

The only time I've ever had a tire "let go" during installation was in the old days of rim brakes on mountain bikes. After a wet winter, the sides of older rims would be compromised from the brake pads/winter grit. I was inflating a stubborn tire for a customer (this is a BICYCLE tire now) and at around 40psi the rim side let go, catastrophically.

There were rim chunks embedded in the ceiling. I couldn't hear properly for hours. Scared the crap out of everyone in the shop. Now, even though I have no qualms about inflating a tire to insane pressures to seat them, I'm still scared of it and take the appropriate precautions.

I've seen video of truck tires exploding and have no desire to witness one in person. I heard a story once (no claims as to the veracity of this story) that had a tire tech not use the safety cage when dealing with a "split" rim off a semi when the tire exploded. According to the story, the upper half of the tech's body was catapulted into the air and landed on top of the shop's sign, leaving the lower half behind.

While I'm not sure the story is true, it certainly illustrates the amount of energy we're dealing with here.

I was having probs last time with a very stiff paddle tire. Wifey mentioned I should heat it up with hot water from the sink.

Worked like a charm.

Me: where did you learn that?
Wifey: Ice road truckers
