Not sure about the life of the KM2's but a mate has been running the old pattern muds for years on an 80 then 100 series cruiser in the 35" size. He normally got at least 80,000km's out of them with a fiar bit of town and highway running and sometimes with a 2 tonne van in tow. He has the new ones now and noise wise they are pretty much the same as my M/T MTZ's and previous MTR's. Quite acceptable on a modern truck with good sound deadening qualities and most of the time driven with windows up and air con on. Not to say they are bad with window down. Like all they tend to get noisier with age. At this stage they appear to be stacking upas well as the old ones and the competition.Mike Morrison said:ILooking at changing from 18" rims with GG AT2's to 16 " rims for better off road capabilities. Is anyone on the new BFG Muds and can they realistically be used as an everyday tyre with regards to noise, milage etc?
