I have had only one nail-like puncture in an XF tire in 90,000 or so miles of driving, and I fixed that without even taking the tire off the car with a "tire worm" plug kit and the air compressor.
in the past 40 years, i have had only 2 times when i noticed a tire was loosing air slowly and took to the shop-it was a nail that was removed and patched. and no flat tires.
makes me wonder how critical is to have spare tire. not for me. but its up to each 1 of course.
