I was looking at the Goodyear Tire web site yesterday
(http://www.goodyear.com/nat/pclt_cat/truck.html) and came across what
appears to be a reinforced tire suitable for our vans and buses. The tire is
the Wrangler HT and it comes in a 185R14C size with a max load capacity of
1708 lbs at 53 psi. The tread is an all-season design "specifically for
on-road use on light trucks, vans, 4x4s, SUVs, and RVs." Just another
option...
