If you need to get through a 7 foot high entrance, and
assuming that INSIDE of the garage is taller than the
entrance, and you can get through a 6' 10" (maybe less) high
door by letting some air out of the tyres for that short
ride into the garage and then you said that you'd put it up
on blocks anyway.  A battery operated air pump will get you
back on the road in the spring after you exit with the
deflated tyres.  Malcolm
