I have a full size spare in the trunk now (205/65 R15 on steelie)

got a free skinny spare from a neighbor recently and thinking to save weight ill replace the full tire in the trunk with this skinny one

the size of the skinny is 125 / 80 R16 its 5 bolt pattern (stamped Ford on it eeeww), but how do i know it will fit my car without taking the wheel off and actually trying ?

thanks -- btw is it worth to save such a small amount of weight in the back im thinking its a difference of 20 pounds at most?

 

You don't really, try, its cake...I would personally just keep the stock spare...

 

yeah im leainng to keeping the big tire too, just fixed up the trunk too, put in a nice thick cardboard piece over the spare and now the trunk is strain, not bumpy from the tire

whats the weight difference anyone know ?
