Agreed Dougal most A/T's give much better mileage than M/T's do. Plus while M/T's are better than they were they still vibrate and make heaps of noise.
Multiple sets of wheels with both A/T's and M/T's while a pain are a much better option for their intended use rather than buggering up M/T's driving around the street looking cool. ...;)
My BFG KM2s are quieter than my GG ATs that I had for a short time. KM2s were a little noisier at very low speeds such as pulling up to the lights, definitely quieter than GGs at 90/100kph. As for economy I didn't care as the KM2s are such a good tyre off road.
How many km do you expect from a set of KM2's?Quote:

The BFG A/T's are good for 100,000km if you keep the steering rods straight, the Michelin XPC pair just refuse to wear out.
I used to have SAT retreads for snow/mud but one died of old age so the rest get retired. Just got some Duratracs to replace them. The Duratracs would likely do 50-60,000km, but I will only run them for a few months a year and don't expect to ever wear them out.
I'm still on my first set of KM2 in LT245/70R17 size. I reckon they have about 50,000km on them, with about 9mm tread depth left. Including 12k km return trip to Darwin and 16k km return to Broome, and lots of fun weekends away.
Agree with discojools - they seem to be noisier at 40-60km/h, and then quieter the faster you go.
Economy is also worse than HT, as they are heavy - esp. on the steel wheels I have. I did reset the trip computer on return trip from Mungo NP a couple of weekends ago. I got 9.4L/100km indicated on the optimistic display from Griffith, loaded up with two people and camping gear on board/on roof racks.
Thanks for the info

The only time 2 sets of rims is an issue is when you didn't plan what you want to do right now, and want the 'other' tyres right now.
I swap between full roads and M/Ts but leave the spare as M/T.
20-30 minutes is enough once you are setup with a good jack and have done it a couple of times. I used to use the air wrench but don't bother anymore, takes me longer to run out the hose and start the compressor than it does to spin 20 nuts by hand.
I normally take 30mins including a good look at the tyres, suspension and brakes. Every couple of times I would rotate the spare as well.
