Hi,
I like to use commercial vehicle tyres... load range C or D... In my experience they offer a much more stable ride and good treadwear....
I have a hightop slwb hiace, though, so it matters more... but have been fitting these to all my campers back to my aircooled VW days...
Michelin Agilis are good, though they seem to have stopped making them in my size...
Continental Vanco look like a good alternative.
Cheers,
W.
