For you all a little lesson on compressors,first if buying one for home dont go by the garb on tank size,ie 200ltrs etc , or the pressure it can obtain, here is what maters,CFM which is the cubic feet par minute that the pump can give at the head outlet,so if you buy or own a spray gun and it states 13 CFM then you should be looking at5 a comp knocking out 15 CFM so it will always be ahead of the tank if it has one, my largest comp was 200 CFM with no tank which is like a road side diesel only 3 ph electric ,i used this to shotblast, no for spraying we had a 20/25 CFM large twin cyl with a 400 LTR tank,two of us could spray from it with care as are guns were only using about 6/8 cfm being gravity binks 630 industrial jobs.
Now for rd side inflation of tyres, again a small comp with very little in the way of CFM is going to take a long time to get a wheel up, and may over heat, so watch the cable length and do give it a rest, better to buy a larger H duty pump and work it from croc clips from the les batteries if pos.
Now for the nasty bit,say a tyre leaves the bead at rd side, well jack her up and spray a small amount of easy start into the tyre and through in a lit match, bang it will blow onto the rim and hopefully you can inflate with your comp.
AS others have said the goo that people put in tyres is fine until you go to a tyre station wher most fitters will refuse to fix, take the tyre and wash out youself before going back near them to fix.
I dont care whats the trend these days a spare wheel is a god send and i would never be without even for those who cannot change it thenselves,AA or others can do so,even a passing truck drive may lend a hand.
Hope this is of some help to folk on here.
