Need some help on sand tires. Should I buy 8 or 10 inch rims with 20" tires? What is a good cheaper tire to go with? Im going to neveda to visit my brothers and they have a place with sand dunes and they told me to get a set of paddles. I will only be there a week and don't want to spend alot of money. Most of the riding I do is just mostly trail and alittle track. If you guys can help me out that would be cool. THANKS!
