I've had mine since June 2001, and the battery is holding up fine, even in the cold weather. The clock function is on all the time, the rest of it shuts down and waits for 1 revolution ofthe front tire to "wake up". The new ones come with revised software that sample twice as often, so if you get one make sure it's the new one. For mine it's a $20 upgrade. I'll probably get the upgrade when I get the trick billet bar clamp holder they have. When the battery does go bad, it's a common one that you can pick up at the drug store or Wal-Mart.

 

I run 20X11X10 sand sharks. I started with 20X11X8 sand sharks, but I didn't like the high sidewall look or the way they dug in when cornering. Make sure you keep a low profile side wall to avoid the digging in and highsiding in corners. If you want to have fun and be able to jack around, avoind the straight paddles.

 

I put a set of 20x12x9 Kenda Trekkers (v-paddle) on an xtra set of stock rims I had from my warrior. The stock Dunlaps were OK in the sand, but the paddles track much better on tight twisty sand trails and steep hill climbs. I'd never go back.

Two things I don't like about this tire.
1) Heavy - this tire design is very rugged and I'm sure I'll never get a flat and probably never tear a paddle.
2) Stiff side wall. So stiff, that It doesn't really matter if I have 3 lbs of air or 10 lbs of air. They are just as hard and unforgiving.

Tire size:
These are 12 inch, but can easily slide if I shift my weight forward. Lean back and they dig well for traction. 12" was a good decision for these paddles.
20" tall - I really wish I had gotten the 22" tires. I can see where it will be real close to the heal guards, but a 20" sand tire with 1" paddles is equivalent to 18" tires (the 1" paddles sink into the sand). This acts like lower gearing and your top speed suffers.

 

[img]i/expressions/face-icon-small-smile.gif[/img]thanx for the input fella's, it wont be long now and i can answer my own question, but i do know this, my stock tires are going with me on the virgin trip this spring (hopefully April 6th [img]i/expressions/face-icon-small-wink.gif[/img]) i always take one spare for each end but i may take more, the whole quad is gonna be a little higher, because i'll be running 22" tires on front and back, i think it will still be an improvement over the scrambler tippy or not.
