I have a Daihatsu Fourtrak fitted with a set of Fulda tyres. The tyres have done approx. 8000 miles. When new the road holding was excellent, however now there appears very little grip and a lot of wheelspin. I do not go off road with the vehicle apart from siting the caravan on to a pitch. There appears to be plenty of tread left on the tyres. Has anybody experienced problems with this make of tyre? I would be grateful if anyone could recommend a better tyre for normal road use with a little bit of site use. Alternatively is the fault with the vehicle whereby it has not got a reputation for good roadholding? Any constructive response would be very much appreciated. Thanks very much in anticipation
