I have now done 140,000 km in 7 years on these tyres including a small amount of off roading - ralative to the total km's travelled. I believe the secret to their longevity is I rotated them every Christmas (summer holidays here in New Zealand) and maintained a 36 psi rear/ 38psi front pressure. My Toyota Hilux 4WD only weighs 2 tonnes. I expect them to last another 3,000 km before I replace them due to the up coming winter. I will not hesitate to get another set of BFG's. The roads in NZ are typically coarse stone chip which causes significant road noise with all tyres. Highly rated in the mud found when off-roading & access roads where I go mountain biking.
