2014 sierra spare tire carrier

[RunGMConly]

I've seem similar issues but not a solution to the issue I have.

I've recently upgraded to aftermarket rims and tires(x5), but the issue I have is the spare tire carrier is too short to hold up my aftermarket rim(larger bore/multipattern).

 

The stock carrier is 5" long and i feel if I were to hit a bump, I'd lose the spare tire, as it only holds it up by a lip, and falls off when I try to wind it back up. 

 

Has anyone replaced the whole assembly to accommodate a heavier tire, and/or has anyone replaced it with a carrier say 6 or 7" long, to accommodate a larger bore?6" would maybe work for me but I'd feel safer with a 7", or inbetween.

 

The tire size isn't crazy big, it's just the rim is heavier than a mofo. For anyone who wants to put a 35" under there, lots of room for it, but increased weight needs to be considered as it's just one bolt and a flange holding that thing up. Storing the spare in the bed is not an option, I want it under the bed.

 

Anyone have a solution?

 

Thanks
