I have KO2's on my 200 Series.and found the steering to be a little bit vague at 40 psi all round. So I had the steering geometry checked. It was fine and the tyre guys fixed the problem by pumping the tyres up to 48.
They said that these tyres have a lot of nylon in them and need to be run at higher pressures for highway use.

BFG are owned by Michelin now.

I made a similar query via an on-line form on the Michelin Aust website and they sent back the attached. I posted it here and the overwhelming consensus was that, apart from the highway pressures, they were too high. I agree.

On corrugations I run about 23 cold. They warm up to about 27-28. Reduced speed, of course

Hard dirt highways about 28 cold, reduced speed

Don't do much sand, but if I did, would be about 15-18

Posted here again for your info.

Cheers

Not too high if you look at the /wheel loads. Most of us aren't at those weights.

I have a 105/ running on 285/75/R16LT and run them on hwy at 40/45psi i find that they wear out in the centre at that pressure. Around town i use 35 psi. I dont use BFG i use Kumho

Which means they are too high !!

I have a 200 series with 285/70/17's, and use the tyre placard as a guide and add 2psi, which means 35/35, and 39 rear if towing.

Never any sign of uneven wear..Tyres are Hancook ATM's

Ran BFG AT's in 265.75R16 size on an 80 series for nearly 12 years.

On advice from an acquaintance, ran them at 32 front and 32-36 in the rear. In about 260K kms, never had a blowout and only a handful of punctures. Never got more than 40K clicks out of a set, but that was a product of where we lived, and err........umm, ah, driving style. They used to chip badly which affected longevity.

"They used to chip badly which affected longevity."

Hi Bob,

Yes, I had the same issue with KOs on my Prado. But the new KO2s have a new compound and are far more chip resistant. Recently did 5000km with the KO2s on my BT50 around Central Aust, Plenty Hwy, Chambers Pillar, East MacDonald Ranges, Old Andado Track, etc at high vehicle weights. No chipping at all.

What a mind field the tyre pressure opinions are. I recently went to battle with BF goodrich KO2's over a bubble I got in one tyre after a trip to the cape. I generally run 40psi on the Hwy, 25-30 on dirt and 16-18 on sand as with every other brand. BF Goodrich told me that 40psi was to low for the hwy and refused to repace the tyre as they believed the bubble was caused by deflation. To which I replied no Shi...t.Fraser Island I had them down to 18 on some of the sand tracks as with the OTT for creek/river crossings. Despite the ill treatment and lack of acknowledgemet from BF Goodrich I have run Bridgestones, Coopers and Pirellies and the KO2 are a very good AT tyre. Maybe I just had one dud??
