My 2wd SLT also has a spare that matches the rest of the tires on the truck. (265/70/17 Goodyear SR-A)

 

Hmmm... Then the "baldy" spare might be unique to packages like my Big Horn. That package simply had so much of the "good stuff" that would've cost an arm-and-leg to option-in separately, well I guess the Dodge Accountants got me back with the spare. I'll just have to figure whether I can use the wheel it came on with a real tire.

So, if you got a spare worth keeping, a Cable-Lock through the wheel and around the "tire hanger frame" would be a good way to go.

 

it kinda looks like a lawn mower tire, hey if you manage to find out if that rim is usable for a good tire if one can be found to work, I think it is a 17 inch rim, would need a thin tire but that is okay for winter as long as it works and is safe. So lets use know size we have to use if you find out all that info. I will see what I can find out,usually by the time the dealership"gets back to me" someone has the answer.
