Thinking about changing to all season tyres in our 1.4 Vitara. It’s done 26k miles and fronts are about 3mm. Current tyres are summer so I’d do all four. Halfords offer the best compromise on costs and convenience.
However I am not sure what to do about the TPMS valves.
Suzuki say the batteries are good for 5-10 years and are sealed inside the valve. As it’s 5 years old I am inclined to leave them alone. They are not cheap as genuine valves (without fitting costs) are £53 each for OEM and about half that for Bosch. But is it good preventative maintenance to bite the bullet? On the other hand is it really much dearer to replace them later if they fail, rather than with a tyre change?
Halfords do offer a TPMS “service” at about £6 per wheel as part of a tyre fitting. It’s just replacing the rubber seals, not the battery. Is that worth doing as a half-way measure?
I did find something online a few months back that said the Vitara had a self-charging valve battery but I can’t find that now, everything points to them being conventional.
Views welcome please.
