When getting a new tyre fitted is replacing the valve at an extra cost really necessary or just a way of ripping you off, I mean the other four tyres are not getting their valves replaced?
Also balancing the wheel when fitting a new tyre, Yes it is very necessary, and possibly quite dangerous not to have it done, so should this necessity not be part of the cost of supplying and fitting a tyre, Supplying goods fit for the purpose,
The valve replacement appears to be a nice earner, as is the balancing, but balancing should be part of the service "There you go sir, nice new tyre on your wheel, but it won't work correctly unless you pay us a couple of more quid"
