So my bearings were messed up and as I was coming home one night the right tire popped on me and I freaked and kept driving home. Once I got home I had realized the tire fell off the rim and shredded the inside, should I just attempt to put a wheel back on and take it to the mechanics? Or can I just repair it at home?
If your tire is "shredded" as you describe, it is beyond repair. There is no way to put that tire back on your rim. Either use your spare tire on your car or use another vehicle to get the rim over to the tire shop, and buy a new tire.
