look, for sand, all you need is a set of paddles... forget brands... although for just playing around, the "V" style paddle would be optimal, better turning. no need to change front tires unless you plan on being a more frequent duner. duning and hillshooting is basically all i do. i run 8 paddle haulers on a 10 inch rim, though im going to some 21x11x8 10 paddles soon, but that is because i am building my bike for it. bottom line is, if this isnt something you will be doing all the time, then find some cheap paddles on rims(no matter the brand) and throw them on. your bike looks pretty stock, so dont go over an 8 paddle and you shouldnt have to worry about wheelying, unless youre poppin clutches. so go, have a BLAST, and let us know how it went.
