What non-standard sizes of tires have been successfully used on the 2WD
Vanagon?  My MXL's are getting thin and I am shopping for something
larger with adequate load rating and no clearance problems.  As we all
know, there is a limited selection of 14" tires that are appropriate so
I'm thinking about SA 15" wheels and larger tires to lower my I-4 engine
rpm and I don't want to have clearance problems.  What have people used
that they like?  And just for fun, what is the biggest thing that will
fit either 14 or 15" wheels?

Thanks.
