Previously I have had 2 sets of the km2s and there where really great so I thought my next set I would buy the new km3s ......well what a mistake that was only done 18,000kms on them and they are noisy as hell and wearing so uneven it's not funny!! Will never buy another set of this rubbish ever again!!!
Do NOT purchase these tyres unless you like wasting your money

Wow, very bad wearing after only 8000 km.
The inside knobs have worn differently from the outside knobs.
Michelin, who makes these have not responded. Very poor handling and braking now.
I will update this review if Michelin do get back to me or honour the warranty without court action.

Have done 5,000kms in them all being bitumen except 1 hr of off-road on intermediate tracks with clay and rocks. All tyres have deteriorated with one front in particular starting to tear 3 knobs off from the back. Contacted Michelin directly as per instructions from retailer and was advised that it’s not a safety issue nor warrantable. Really disappointed considering the amount of research I did prior to purchasing a so-called quality product.

I have always had the BF Goodrich mud terrains on my GQ Patrol, and these are a step up from the already impressive KM2s. The last set of KM2s I had were down to 10mm tread from the original 14mm after 50000km, at which point I upgraded to these. The grip on wet tarmac has improved over the KM2s and road noise is less than most all terrains. They bag out nicely when aired down and grip is awesome in mud and high speed gravel driving. These tyres are on the expensive side but when you’re getting over 100k out of a set they represent good value.

I had KM2's previously and loved them. The new KM3's feel harsher, have less tread and cause a lot more noise on road and seem to hold stones in the tread more than the km2, even though the opposite is stated by BFG. 12000km in and very little wear. Traction is great in both wet and dry on all surfaces. Are they an improvement on the KM2's? Looks wise they are, the rest of it I'm doubtful about.
