Hopefully those 215/65's are reinforced or XL rated. Otherwise they are at
the lower limit of acceptable capacity for the Vanagon. Especially if you
subscribe to the 10% de-rate when using passenger car tires on light trucks.

I swapped my steel 14" rims for 15" Alloys with 215/65 tires.  The 10/10
calculator shows my revs/mi as 800.  My speedometer says 820.  So I guess my
speed will show as 97.5 percent of my actual speed. So when my speedometer
shows 65, I'm actually doing 67.
