On my newest finished car I wanted a spare tire to match the tires I put on the car but outer diameter was too big for the early a spare tire well. (This was something I overlooked on a total rebuild.- ugh!)
I needed a tire combo that would clear my calipers AND fit in the spare tire well AND be really close to the outside diameter of my existing wheels so my locker did not explode slipping. My goal was not a spare for 500 miles but one for “just getting off the highway.” Donut spare tires were my inspiration, but I was unable to come one that fit due to offset. They stuck so far out they hit sheet metal. So I found a really skinny tire. 4” wide x15” diameter. And put it on a very skinny version of my rims.
Pictures have the part numbers and sizes. No need to repeat the obvious. And the now spare is only 1/2” smaller in diameter to the current wheels. Remember the factory wheels even the KH 14” still were like 24”od.
This combo my od is like 24.5” full inflation.
My current tires are 25” od.
I hope this helps someone with a spare tire bouncing around in their trunk or with no spare at all. Good luck- Joe
