I'm thinking about running 4 rims total for a few miles to the tire shop. I have two blown tires and it would be easier to do it this way. Any major issues I'm over looking?

 

I'd just not load the truck and run it to the shop. Personally I can't see it ruining anything.

might be wrong.

 

You can run it to the shop that way

 

you will be fine...

 

Yea go slow don't load it down

 

I saw a truck heading up I-75 the other day with the inner tires only. it looked really weird from behind it....

 

Just make sure the threads on the lug studs aren't beat up or too rusty where the outer rim usually sits, as you will have to tighten the lug nuts down more than normal since your outer rim isn't taking up space. Make sure they will snug down tight or you will ruin your inner rims. Other than that there is no issue running singles.
