Good quality truck tyres with 15-18mm drive pattern do this when nearly new due to the tread flexing when scrubbing but then they settle down. I think BFG have softened the compound now to comply with US noise regulations and i don't think you have a fault but just good tyres doing thier job which looks like hard cornering.

Also IF* it's on the off side of the truck maybe round abouts not helping

Its the near side

Looks like heat degredation by tyres doing hard work.

I'd agree, looks like you have been spanking it around and the tyres have heated quickly. Nick

I've had mine on for 2 years and 9,000 miles with the majority of the mileage off tarmac. Just had a look at mine and there's no sign of cracking or degradation.

It could be (as mentioned) pressures (mine are 32F/35R) or as both tyres in question are on the same side then perhaps they've been subjected to a chemical whilst on the road that's reacted with the rubber?

Worth asking the supplier (or perhaps Andy AJS) can advise if BFG are aware of customer issues with the KM2's and if so is there a goodwill process in place?

Looks normal to me, just been pushed hard on the road. Nothing to worry about.

Just went to check mine... BF Mud KM2

17000km and allready showing cracks on the back tyres!

The ones I had on my 90, (the old BF Mud) only started to show these signs about 45000km of use ...

Could heat or consistent high speeds be anything to do with it?

Doubt constant high speed, we cover lots of miles for hour after hour and have had no issues. 130's have feeling's as well you know

Mine have 40k on and are wearing well but you have way more tread if you want to swap

Hope you get it resolved though

The pictures show some residual spray of some kind. Chemical or perhaps it is fine rain? 59 2.4 110 XS Utility

As a previous tyre developer and being a polymer chemist I can offer an informed opinion.
Although there are reasons why a tyre may chemically craze or crack the pictures supplied illustrate typical hard cornering damage which is especially prevalent on new tyres with a block tread pattern. it should diminish as further wear takes place.

I am in a hot climate with around 50,000km on mine with no signs of cracking other than when I have not reduced air pressure over rocks.

Any problem you think you have go see a tyre dealer for advice.

Looking at the photos I would look at tyre pressure and driving style.

My gut feeling as we can only see photos is "if" they were sent back for inspection the letter would read............ No fault found. Andy.
