What tire size should I be using and where can you get them?
185-14 Load Range C Not sure you can mount 185 60 R14's but this size exists. I suggest you see a local tire supplier and talk to them on what you can you order and or fit. Also try www. tirerack.com
Cokertire.com carries vintage sized tires.
I cannot emphasize how important it is to get the load range C... the Vanagon is heavy...and top heavy at that. If you don't get a tire with a lot of side reinforcement, the tire will fail prematurely and dramatically. Check out the article on Vanagon.com There are lots a great tidbits of information there.
