Rims and tires

Get some Douglas .190 rims and put some Maxxis iRazr's or Bill balance tires....20in tires are really good perfect amount clearance, and you gain torque if you have the stock 21in tires....
 
and if you get aluminum wheels get .190's or you'll just bend them up on the trails. and i agree with the 20 inch rears, with a 21 or even 22 inch front for clearance if they're rutty. i'm gonna try 18's on the rear and 20's up front but man they look tiny

i got 18's and i ride alot of trails. there usually fine but sometimes i scrape a rock or something.
 
go for 20 inchers, i have 18's and they aren't great for any trails, i run 22 inch mudders on my trails and rip but they don't slide, so i'd say 20 inchers, get some itp holeshot ( 6 ply) or some maxxis razr 2's or just plain razrs, also, my recomendation for a hardcore trailrider is beadlocks for rims, they will come back and save u some day, and they look cool, if u don't mind spendin the extra penny
