I'm rambling a bit…but.. took the truck to the local tyre joint for a very slow leak repair.
An hour later the old girl was parked out the front resplendent in her (yellow striped) space saver.
"We tried to plug the hole but it was still leaking a bit.. you need 2 (really4) new tyres, the leaking wheel is in the back."
Drove to supercheap, bought a bottle of sealant
Went home and put the leaking tyre back on, deflating the space saver was nifty, it just folded itself back into the rim.
Went for a drive, checked the repair, leak sealed , game over
Needs tyres soon anyway.. but at least I get time to sort out a deal...
