More recently, almost all truck tires were in-box, and to replace them, a sledgehammer, corners for beating off a side and a couple of strong ontings were required. With the advent of tubeless wheels, the techniques and tire fitting technique changed radically. To remove / put the tire on the disc without damaging them, tire changers are needed.
A modern cargo tire is expensive. Imported middle-class tires by 22.5 inches will pull thousands of ten rubles, and there are a lot of cases when a completely new rubber had to be thrown out due to rupture of the rim flange and other damage caused by illiterate installation. Moreover, the defect often does not manifest itself immediately, but after some time, therefore, in most cases it is not possible to make a claim and receive compensation.
Is it worth trusting tire fitting to a third-party company if it can be qualitatively done on its own. And tires are guaranteed to remain intact, and you will save money, and if you want, you will also earn from servicing cars from the outside.
