Had a similar result when fitted MTRs to the D1. The BIL had a similar effect when fitted Mickey Ts to his 80 series. Braking distances also increased.

Bought the 17' rims with the Coopers on them, so will use them for trips away.

I went from the OEM 18' scorpions to the BFG A/T 17's,both same diameter,made no difference at all.
Except the A/T's are noisier.:(
I noticed the same thing with my old 80 series cruiser. 265/75/16 goodyear MTR's used a bit over 2L/100km more than 265/75/16 Bridgestone AT's.
Ean - I have the same experience. 18" Wranglers to 17" BFG KM2 MTs and the economy goes up by about 2L/100km. I think it is not just due to the increase in rolling resistance, but also the increased weight. I weighed them a while ago and 18" std wheels with Wranglers were 28kg, while the 17" factory alloys and KM2 were 36kg! That's 12kg per corner of extra inertia to overcome. BTW, the steel 17" wheels I had on my D3 with KM2s were 42kg each!

I run 18" Kumho "Road venture APT and average 10.5k/100L. (less if I reduce my overall speed) The tyres are cheap, V speed and R load rated and are quiet.
After 3 sets (of 6 tyres), I have never had a problem with any of them running at speed in hot remote environment. No separations, no blow outs. and they are cheapish at around $210-225 each.
Hi Ean,
I went the other way.........I had GG AT's on the car I picked up a set of the same RRS rims quite cheap that came with some entry level HT tyres on them with 80% tread so I'm just using them, much quieter and I'm getting about 1 ltr / 100 klm better fuel consumption, these new rims just keep on paying for them selves.............. same rolling diameter.
Cheers Marty
I went from 18s to 265/70/17 Khumo ATs never noticed any real difference, then to 245/70/17 BFG KM2s and still didn't notice much difference, our economy has always been around the 11.2L to 12.5L/100ks around town, no matter what tyres are on the car, with 10.3L/100KS, as our best on the highway/freeway with the 265/60/18s on, haven't done a long highway run with the 245/70/17(30.5") KM2s on.
Did you do anything else when you fitted the 17s.

By the way Ron moon is full of **** i have slready changed a tyre due to a slow leak in only 800ks.
Cheers Ean
13L/100K towing the camper:eek: I'd be over the moon with those figuers towing, I get between 14.5l/100k to 16l/100k depending on terrain, towing our 1400kg to 1500kg camper and that's with our 265/60/18 D697s ATs and not the KM2 muds:(Quote:
