you can. but generally, most tire shops can balance a 33 or less. and they tend to balance easier. when you get into the bigger sizes, they are never as true as the smaller tires are. and not every shop is set up to balance tires bigger than 33s. Hell when I first got my 35s, I had to go to 8 different shops before I found one that could do it.
but of course, the problem with rim weiughts offroad are plentifull:
1. when you air down, your tire can and will rotate itself on the rim as you wheel, thus displacing the weights and throwing the balance off
2. rim or stick weights will break or get torn off completel;y on the trail, thus throwing the balance off
3. though rare, i have seen it happen where somehow a weight gets tweaked and pushed in to the bead of the tire. it didn't puncture it, but it was a PITA to remove
by using an internal balancing method like BB's or air soft or whatever you like, you eliminate all these problems and your tires are now self balancing.
oh and for the guy asking if he used to few airsoft pellets, yeah you did. normal reccomendation i've seen is 7 ounces per tire for 35s, then add an ounce per inch over that
