Actually, in SR, the S is a speed rating, where S, T, H, V, Z, etc 
list increasing max speed rating for car tires. All else being equal, 
the higher speed rating usually means stiffer sidewall (=less heat 
buildup) which would be desirable on a Vanagon if LT tires cannot be 
found. Based on my experience with performance tires, I wouldn't go 
any less than HR if you must go passenger tires, and make sure the 
load rating is adequate, ie ~1300lbs+ at max psi.

Not true. My current Michelins on my Jetta are guaranteed for 140,000 
km - the stock ones were lucky to last 80k.

Generally speaking, higher speed ratings mean faster wearing tires, 
but this is not always true. Compare treadwear numbers within 
comparable tires of same speed rating. Higher = longer lasting.
(my michelins are 440)
