the spare on my komfort 21T came mounted under the chassis just in front of the axles .
it winds down just like the spare in my duramax .
the trailer supply outfits have that mechanism for sale for retrofit .
However on my boat trailer i travel very long distances at night without a spare .
on my boat trailer i raised my fender 1- 1 /2 inches , increased my wheel size by an inch , increased my tire width by about an inch , increased my load range by one rating , and increased my load rating on my tires by about 38 % .
i now have so much reserve capacity in my tires that i do not carry a spare .
i check the tire pressure before every trip and i put my hand on the tires at every rest / fuel stop to see if there is heating in any tire .
i have had no failures , to which i attribute the excess tire reserve capacity as stated in pounds on the tire sidewall .
I chose to spend the money i would have spent for a spare and put that money into the tires that are on the ground carrying the load .
One roofing nail will kill all of that reserve, and then what?
