Hey guys
I got a tyre pressure warning light this morning on the way to work, (rear left, check all tyres and reset etc). I pulled over and took a look and couldn't see anything out of the ordinary: being late and only having a couple of miles to go I carried on, pulled over after half a mile and it all seemed fine, pulled over again after another half mile then continued to work.
I got to work and checked the pressures - all were down slightly as I hadn't checked them for a few weeks, at mid-high 30s (psi), with the rear left at 22psi. When I left work this had dropped to 19psi. I limped home (5 miles, very carefully with regular stops to re-check) and pumped up all 4 tyres (rear 44, front 46). This was about 7 hours ago. After leaving them to cool down for a few hours they all lost a couple of PSI, understandably because they were warm, but the rear left is losing significantly faster than the others. I just checked again and that rear left is down to 39 already.
I'm going to have to use it tomorrow to get to work, so I figure I'll pump all 4 up before I leave (petrol station is 100 yards away) and see how I get on, if necessary using a colleague's foot pump for a booster before the end of work.
My questions:
Thanks

My questions:
- Is this likely to be repairable
- How long am I likely to get away with pumping up before a 5 mile journey, then leaving to stand for 12 hours? Presumably it will cause extra wear
- Could/should I use the tyre weld stuff in the boot? It should seal a hole temporarily, I know, but I've heard that it gunks everything up and makes it difficult/impossible to repair the tyre.
- How much pressure am I likely to lose from that quick blast of air each time I put my pressure gauge to the tyre? I've been trying to check regularly to keep an eye on it, but if I'm just letting out several PSI of air then I'm probably doing more harm than good
- Would a 100 mile round trip be a completely stupid idea? I'm supposed to be going 50 miles on friday and back on sunday. If I filled the tyres before each leg, would I still be safe when I got to the other end, or would I be risking the slow puncture becoming something more serious?
Thanks
