I can vouch for these numbers as my van, single axle, 2.6t [bigwhistle] followed me for 25k Km on a pair of these. This included a trip to the Birdsville Races & numerous other dirt road trips without a single puncture. I was forced to change them because of my really bad wheel alignment (my fault) but this is a pic at 25k km after carrying all that weight.
