The spare is for 08-19 Ford Taurus. T135/90 on a 17"x4" steel rim. 5 on 4.5" bolt pattern.
The T135/80r17 26.5" Diameter is somewhat snug in the AMD spare tire well when fully inflated...
The well is not perfectly round and has room on 2 sides and touches on 2 sides. Not sure if that is the same with original wells. "¯\_(ツ)_/¯"
I did have to enlarge the center/hub opening to fit my Mopar hubs.
Will probably change to a T135/80 ~25.7" diameter to match current tire diameter we have for the car.
This size will fit the spare well fully inflated.
Tires we have for the car are 275/40R17 and 245/45R17, they are both about ~25.7" diameter.
