Classic Auto Air Belt alignment fix

I know on my snow blower the pitch/angle of the V on the belt has to be spot on with manufacturer specs otherwise it slips and wears out. I tried using a generic belt on snow blower from local auto parts store after a few uses belt would wear down cause V angle didn't have enough contact. Not sure if automotive V belts vary in the V pitch like that.

Sort of weird they always provide a two belt compressor with those AC kits but out of the box can't run two belts?
