Your site claims: "based on the GAWR (Gross Axle Weight Rating) of a Bus or Vanagon you get the following minimum acceptable load ratings: 1520 lbs (load index 95) for a light truck rated tire, or 1670 lbs (load index 99) for a standard Passenger car (P) rated tire," which implies a GAWR of 3040. You offer no source for "the 6% safety margin" you say is required in addition to the 9% derating for a passenger tire used in a light truck application. There's no mention of the additional 6% here: http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=70 A light truck tire rated for 1520 (1/2 the Synchro rear GAWR) would be load index 95. A passenger car tire rated for 1672 after derating 9% is load index 99, which agrees with the load indices given on the busdepot site. Interestingly, if a passenger tire had to be derated 9%, then an additional 6%, as claimed, one would require a passenger tire rated for 1914 lbs, or load index 103. So, the busdepot site doesn't even follow the rules it claims to use. But, a 2WD has a rear GAWR of only 2866, so tires need not be rated to the same capacity. As I said in previous posts, tires suitable for normal Vanagon must be rated 93 (if light truck) or 96 (if passenger) or better. |
