Andrew, you may be not familiar with Costco. Its tire department will not sell
tires not meeting the requirement to Vanagon owners. They used to have one model
specifically stocked for Vanagons. That's when I got the tires. It has the correct
load index with reinforced sidewall. They have proven to be very durable tires.
I often used my Westy as a truck carrying 500+ kg of load (drums of liquid) roaming
on local freeways. The only problem with these tires is that they are more likely to
skid when braking hard.
Costco's technicians don't really know the requirement for Vanagons. But somehow
the sale person at the front desk knows to say no to me these days. They simply
do not have the right tires for Vanagons any more.
I have the correct tire pressure on them. Actually I put slightly less pressure now
since the tires are getting old. Still I have 38 PSI for rear and 35 PSI for the front.
I would pump up a few more PSI before using it as a truck.
