My 2001 gasser (19.5inch tires) came with a spare...in a spare tire compartment. I was told that in later years,this was discontinued.
With 22.5 inch tires, yeah...I can understand that. Heavy. Impact gun needed. Absolutely. Plus the fact that the 22.5 inch tires are (as I'm told) the same for 18 wheelers, so replacements are easy. With 19.5 inch tires, not as heavy, impact gun preferred...but Coach-net always asks if you 1-have a spare and 2- does it have air? (Replacements are more difficult as truck tire outfits don't generally have spares) My response to both are: "yes". Even tho...the TWO times I needed Coach-net for tire problems (on the road) their trucks had air compressors on them ready to use.
