I change mine myself. I don't have a local shop, and the zuki shop gets $100 a tire, the hog shop get $25 a tire and try's to sell me shid I don't need and fugged up my rear brakes costing me four trips.
Bike tires are made so well that I make sure I've got the direction correct and align the mark with the stem. 6th rear wheel, factory wheel balance no issues.
