I've recently bought a 2010 Defender 90 which had had new black saw tooth wheels put on it with heavy duty Goodyear Wrangler tyres. I get a whirling type noise ( woh.... woh...woh....who....woh..) which gets faster the quicker you go and persisted when the clutch is engaged . Is this likely to be normal tyre / road noise which would be expect or could it be baring noise. Is there anything I should do such as check tracking or balance of wheels?
