I tried to pump them up the night before. That's when i found out the caps wouldn't move,so i took my pliers to the air pump last night and tried there. I didn't turn them too hard,as like you say,i thought the valves might snap off and i'd be half a mile from home with a flat tyre.

Yeah,but if sturdy pliers won't shift them,will a small spanner?

Pliers aren't as good as an adjustable that gets grip on two sides.

Something tells me this'll end with me taking it the local tyre centre,where they'll snap the valves trying to get the caps off,then discover 'my tyres aren't safe' and i end up buying 4 new tyres!

You see all those burnt out cars? They had stuck valve caps...

Check the tread yourself and be happy they are legal before going to the garageSomething tells me this'll end with me taking it the local tyre centre,where they'll snap the valves trying to get the caps off,then discover 'my tyres aren't safe' and i end up buying 4 new tyres!

Good point. Stuck valve caps do carry a derious risk of explosion.

Yes it's something to do with two different metals, one on the thread of the valve and one on the thread of the cap and they fuse together. There is a name for it but I can't remember it.
If you Google something like tyre valve caps won't come off my BMW there are from memory quite a lot of articles about it.

Galvanic corrosion
I think it's called galvanic rust It's were two different types of metal are in contact with each other the moisture in between them creates a tiny electrical charge resulting in the two metals rusting up together. Old land-rovers used to suffer from it. The Aluminium skin would react to the mild steel that they can into contact with.
