Something Odd Happened

Something odd happened to me on my outing a week ago. Checked the tires before leaving home and all pressures were spot on. Not a big surprise since I use Ride-On tire sealant and my tires rarely need to be topped off. Drove about 30 leisurely miles to a gas station, mostly on 35mph-type paved roads but also a couple of 55mph paved stretches. Rig felt fine the whole time. But when I stopped for gas my front tire was flat. Not a little soft--totally flat!

First of all--thumbs up for my Heidenau K60 Scout that not only stayed on the rim with no air, but didn't even give me any shakes or shimmies.

Filled the tire and checked for punctures/leaks. Found none. Just a little bit of seepage between the tire and the rim that I figured would go away as soon as I got going and the bead got better seated. Did about 100 more miles that day, including about 20 miles of dirt/gravel, stopping frequently to check the tire. No loss of pressure. Now, a week later, and the tire is still holding at 30 lbs which is how much I put in at the gas station that morning.

What's up with that? How did I manage to deflate my front tire without puncturing it or damaging it?

Hey Drone....I don`t know what that Ride On stuff is composed of....but I do know that Dyna Beads, (which are very small ceramic beads)......will once in awhile, when you check tire pressure... as you did....get stuck under valve and cause a slow leak....what I do is give tire a quick blast of air before taking pressure reading to move beads away from valve....

PS...I don`t check pressure when away from an air compressor source....

Ride-On is a liquid and it can spit out of your valve stem if you have alot of the stuff in there, and then check your air with the stem in the 6 o'clock position. But I always check my air from the 9 o'clock position. Anyway, if there was any Ride-On in the stem it wouldn't make it leak, it would make it not leak.

PS--I always carry a compressor and tire kit on board with me.

I have had a valve stem core stick down AFTER I have checked the pressure.Putting the cap on would keep some of the air in but I think after sometime it would all leak out.I had to pull out the core and clean it off and put it back in.Just a thought.!!!!!

That would certainly explain everything that happened before and since. As a matter of fact, now that I think about it, that was a new core that I put in this Spring when I mounted the new tire. I think I'll pull that valve core and clean it. Or maybe go buy a new one. Thanks!

That's too too funny! That's why I put in a new core this Spring. The old one flew out into the yard somewhere when I was deflating to install the Ride-On.

You guys must be bad luck. This evening I went out to mow the lawn. I was checking the tire pressure and the right rear valve stem stuck and all the air (with a bunch of slime) squirted out. Drone, I am convinced that Slime and like products cause the valve stems to stick open as they gum up. Ten minutes later I stuffed my tractor in the ditch. I had to yank it with the Jeep and help of my neighbors.

Trouble comes in threes. Watch yourself!

Back to the mysterious sudden air loss -- after all those suggestions -- I ended up not doing anything about it before I left on a 2000-mile camping trip. Just came back. Had to add about 2 lbs halfway through the trip. That was it.

Edit--never happened again. Ran that tire down to where it was almost smooth. I think somehow or another I must have broken the bead that morning and lost all the air just a minute before I noticed it.

Total weight of the rig

Had a chance to ride my rig over the scale at my local dump and thought I'd share what I found out. With dog and camping gear and a half tank of gas, I rolled in at 1320 lbs.

30% (400 lbs) was on the front wheel, 20% (260 lbs) was on the the sidecar wheel, and the remaining 50% (660 lbs) was on the rear wheel.

Weird that it came out so even at a perfect 30/20/50 split. I measured it both rolling on and rolling off the scale and got the same readings at both ends.

For reference, I think that the rider and passenger, tools, equipment, camping gear etc that I had on board with me when I hit the scale weighed around 450 lbs so that leaves the outfit at about 870 lbs naked (but with panniers and other farkles). Seems reasonable compared to BMW's published dry weight of 550 lbs.

WestFest camping trip

2000-mile camping trip with Kirby to Montana (WestFest), Idaho and Oregon. About 400 miles was dirt or gravel roads--90% Forest Service roads. The highlight of the trip in terms of sphincter control was probably going DOWN the Kleinschmidt Grade (pics below) into Hells Canyon. If you don't know this road, Google it. Drops 2300 feet in about 5 miles - one lane of dirt with turnouts - and if you make a mistake you won't stop until you splash into the Snake River! I actually DID splash into the Snake River, but that was after parking the rig at the bottom. It was about 90 degrees and Kirby and I both felt like a swim.

No problems with the rig at all except I'm now convinced that I need to beef up the springs on my shocks (like Boxertwin told me three months ago!) My Heidenau K60 Scout is wearing down quite nicely giving me a fine square tread on the front. Front braking is better and left hand turns are more solid (I was getting some drift when the tire was new).
