What's the max tire size for storage under the vehicle in the spot where the factory spares rides? Will be using 17" wheels. does width of tire play a role in that or just "height"? thanks. Brand new here and preparing to buy and outfit my first GX470

 

Remember reading on IH8MUD the max inflated tire size that will fit in spare location is 255/75/17

 

I have a 265/65R17 up in there right now and it looks like there is about 1/2-3/4" space open around the outside of the tire to go bigger.
