The new Fat Tire bike just arrived!
The gas Fat has 3.5" rims with the fattest part of the tire at 4".
This electric Fat has 4" rims with the fattest part of the tire at 4.5".
KC, I wonder if you could measure the sidewall profile of both tires. Also, who manufactures the tire on your Crusher? They're both very nice rigs...Steve
The size specs are in my post you quoted hehe ;-}
The tires are what came on the bike, pretty easy to find as well as other info from the bike builders pages and something I simply don't have in front of me.
