A standard golf cart tire is 18X8.50-8. 18 is the diameter in inches, 8.5 the width, and 8 is the rim diameter. Some possibilities for upgrades:
205X50-10 (18.07X8.07, sidewall height 4.04)
205X65-10 (20.49X8.07, sidewall height 5.25)
215X30-12 (17.08X8.46, sidewall height 2.54)
215X35-12 (17.93X8.46, sidewall height 2.96)
215X40-12 (18.77X8.46, sidewall height 3.39)
215X45-12 (19,62X8.46, sidewall height 3.81)
I'm planning to upgrade the wheels and tires on my cart this year. There's a bunch of carts in my neighborhood running the 205X50-10 tire, which looks great. There's a few lately running the 215X35-12, but I'm not too crazy about the much smaller sidewall.
I was kind of set on getting the 215X45-12, but I'm not sure I really like the 12 inch wheels anyway. I do like the idea of increasing the diameter of the tire over stock though.
If the 205X65-10 really does fit it could mean a pretty good speed boost. (20 mph on a 18" tire, would be 22.68 on the 20.5")

I'm hoping someone here has tried either the 215X45-12 or the 205X65-10 on an otherwise stock EZGO electric.
there I was, minding my own business as usual, when all of a sudden.........
