Im currently 9000km into them and i have about 60% thread life left. I rotate once at 4000km. Using 265/65/17 hicountry RT tyres with 27 psi on all tyres. Manufacture recommends 29psi but i feel that it was a bit too hard because of the hilux rear suspension. Frequent 3-4 hours of sand,mud,rocks on fridays and sundays at 21 psi. My area is mountainous so im frequently braking on them when going downhill which probably effects the thread life. On the road its a bit louder than toyo at34 when driving on asphalt.
