Have two job offers and I'm ndecisive

Got an offer at Autozone as a retail associate and commercial driver and another at an independent tire shop as a general service technician. The problem is the tire shop already has me scheduled for next Wednesday. Autozone still doesn't have a finalized schedule for me, but it might be Tuesday.

Autozone will $13 and hrn the tire shop is $14 an hr during the probation period, then it's $15 after. I want to work on cars, but the tire shop doesn't sound all great, with 7-5 shift and a 30-minute break, and there's no upward mobility like the Autozone, but Autozone sounds kinda boring tbh. I've been thinking about it for a few days now, but I need to make a decision by the end of today. I don't know if I'll be able to work both jobs realistically.
