What are good paddle tires for the Z? I am looking at the Gecko's and the Paddle Masters. We dont have many big hills here but lots of sand. I also heard the Sand Skate II is a good tire. What about fronts? A good front with some decent trail/dirt traction? Mohawks? Do paddles work good in the snow too? I've never had a set of paddles but this new place to ride is all sand and paddles are a must! Which do I get? I like the 10" rear rims too. Any disadvantages to the larger rim size?
