Two days ago I got a set of colway ats. Checked pressures and went out yesterday. At lunchtime I noticed the front tyre was looking a bit flat. It had lost quite a bit of air. Put air in and came home. Checked it last night and it was ok. checked this morning and it had lost a little air. What I failed to notice was the back tyre had lost a lot of air. re inflated them and they were ok till this evening when they had lost a little air again. Have taken them off and thoroughly checked for any sign of punctures and can't see anything.
My question is this;will they settle?

Unlikely, I'd whip them off, get some soapy water, lay them down and run a little around the tyre/rim joint and see if it bubbles, same with the valve area. Did they fit new valves when they were fitted? Also are they steels or alloys? It could be the rim needs a clean up as they either have rust or corrosion stopping the tyre seating properly, they may need new valves (I have had bad new valves before) or the may just need taking off and reseating, they shouldn't leak if they've been fitted properly. In rare cases alloy wheels can become porous if these are new to you rims it could be why the previous owner got rid of them.

In addittion to Phils practical suggestions, something I have come accross with alloy wheels (the metal of which is relatively soft) is that they are easily scored/scratched/gouged on the sealing face if someone has used a tyre lever in changing tyres. So a carefull inspection and feel around might be productive, with dextrous use of a fine file if neccessary.

Tyres on an alloy rim must always be changed on a tyre-fitters machine, and with care.

They are steels and in good condition. No problems with the tyres that came off the rims. I went back to the place I got the tyres today and they took them off and re-did them. Hopefully they will be ok. My neighbour lent me one of those plug in the cigarette lighter tyre inflator thingies and found it so usefull I'm off out to get one for myself.

Yeah they're great, I've had one for a little while now after my old footpump blew up after many years of hard wear, it's a lot easier on the leg muscles thats for sure!

Many tyre fitting companies now use silicone sealant as a matter of course .... the self same stuff used in the building trade.
