quite easy first pick you hex adapter
14mm for maxx trucks
17mm for truggy, savage and some others
23mm for some proline wheels used mostly for bashing
ok u got truggy so 17mm
now the wheel size
standard truggy wheels are 3.2" diammeter
LRP (low profile) wheels are 3.8 diammeter
now wheel offset:
0 offset for all new truggies i think
1/2" offset for some older like losi, ofna what need offset wheels to get the needed track width
and then just pick correct tire. easy
or even easier just buy premounts like i do
