Long story.......
When we bought the car (at auction) all tyres were shot. We bid for and won a set of unused Pilot Primacys on ebay. Got all four for £210:bannana:
However......the seller was in Pontefract and we're near Edinburgh. Good excuse for a wee run. When we got there the seller took pity on us and gave a £10 refund for our fuel.
bannana: again.)
The tyres have been nothing short of amazing. Rears replaced at 26000 and fronts now needed at 32000. Given the torque the car lays down and the oft imposed resistance (heavy caravan) the rears are forgiven their increased wear rate. Made the mistake of putting lesser brand on the rears and the car feels def more skittish in the wet. Also there is evidence of the wear being vastly increased. False economy big time. I feel it's not worth experimentation with alternate brands: Michelin do it for me regardless of cost. Getting to your noise question. I can't say the cheapo tyres on the rear are any more or less noisy than the Michies. Avantgarde suspension is not as compliant as it might be for comparing tyres.
