On Saturday, I drove two hours to the foot of Mount Rainier, to climb to Paradise. I was looking forward to a 5,000 vertical foot climb over about 20 miles. It was a gorgeous day, and there wasn't a cloud anywhere in the state, except the west side of the mountain ... it was a bad omen.
I had thought taking the snow shoes out of my trunk would be good for my wheels, instead of setting them on top of something metal, and then hitting a crack in the pavement on the freeway. Well, there was part of a staple or something in the bottom of the trunk, and it found its way into my rear tire. I parked the car in Ashford, got the bike out of the back seat, pulled the wheels out, and one was flat. A can of cafe latex turned it into a slow leak. I rode about 5 miles, and it just wasn't working. This is when it started to rain - I could have got a sunburn if I'd stayed at home.
Two more hours in the car, and I stopped at the LBS. They took part of the valve off, pumped the tire full of sealant, and sent me on my way. I rode 35 miles that evening, enjoying the last of the sun, and it was fine. The next morning, it hadn't lost any more air than the front tire. So I pumped them up, then went and rode 20 miles in the foot hills, closer to home. The valve blew out at the end of the ride, about a mile from the car. I rode back to the car slowly, keeping as much weight as I could on the front wheel.
At home, I tried pumping the tire up. It was good until about 120 psi, then sealant started coming out of the tire. It stopped somewhere around 100 psi, and held air after that.
The tire has about 800 or 900 miles on it. I'm not going to do abdominal surgery on a snake. Do I need to replace it? Should I try more sealant? Any other options I have? I've ordered a double wheel bag, so this won't happen again. I ride a lot in remote places. And I like exactly 120 psi in the rear wheel, it doesn't feel right when it's much more or less than that.
