Dave,
My 37 has 10 lug in the back and 5 lug in the front. It is the same wheel with a cosmetic plate to hide the holes that are not being used.
The tips on vendors for tires is good. I almost went with Nebraska tire but after shipping and finding a local address to recieve them the cost was close enough to a local guy that I just bought the local tires. Expensive though $200 a tire tube not included.
