Horizontal spare wheels

I had an interesting fallout form a puncture on my box trailer last night, and thought I would share it so that nobody else gets caught out.

Usual story of a puncture, tyre went pop, trailer leans over, so I pull in and change the tyre. No drama....until I pumped the spare up.

The spare gets pumped up by me sort of regularly - ish, primarily because it is mounted horizontally on the drawbar and by keeping it pumped up, the upper tyre rim is kept in contact with the top wheel rim. Actual pressure is mildly irrelevant, as I have a foot pump in the boot of the car so can top it up as required.

Said spare has been there for well over 7 years, but has spent a small proportion of that time fully inflated, mostly sat there at about 8-12PSI. As I pumped it to working pressure, I realised that it started lo leak round the rim. drop pressure to the storage pressure - stops leaking. Turns out that because it has spent so long on it's back, all that nice grit & road dirt that accumulates had been washed into the crevasse between the tyre & the rim which forms a nice dirt trap.

When Pumped to working pressure, the tyre expanded slightly closing the crevasse, where the grit pushed it away from the rim. No problem I thought, a few mins at 60 will clear it..... Nope. I had to stop every 5 miles all the way home to pump it up to working pressure.


The moral of the story -Those of you with horizontally stored spares either make sure they are kept at working pressure or covered. I am going to buy a full cover for mine this weekend.

I moved my spare wheel on the RIB trailer from horizontal on the draw bar to vertical on the side frame only a month ago, partly for your reason and partly because parts of it were flling up with rain water.

Mine is mounted semi-horizontal (it's a bracket designed to sit under the bow of a hard boat parallel to the flare of the bow, but it sat too low, and as such got turned 90 degrees.) It collects a bit of water in the bead, but not much.

It stays at working pressure.

Makes a handy table for lunch as well.

Mine is mounted in the back of the 110 - it smells a bit odd, but then, so does the 110....
