So I am with you Comms... My lovely bride reported to me that her SUV has a flat and I should wake up (at 4 in the morning) and take her to work then fix her flat tire.

After the sun rose and I could see what I was doing without manmade lighting, I proceded to take her tire off and have it repaired. Upon returning from having it repaired I tried to put it on the vehicle to no avail. The SUV had to be jacked up higher. No prob, but the jack was MAXED out. Still not a prob. I have a lifted jeep I DO have a jack that will get it high enough. But now the other jack out of my jeep is too tall to fit under the SUV. Damn it! Not a problem. I pulled out my credit card, took the trip to the auto parts store and bought a 2 1/2 ton floor jack. I put the floor jack under the SUV jacked it up put the tire to the lug nuts and it was 1/2 inch too low. SON of a ^@(^&(&^!

To answer your question I ended up using a block of wood that I had in the back yard to get a little more lift. Ya I was not going to qualify for the pit crew award for fastest tire change coming in at 2 hours.

By the way, now I have 3 jacks none of which will allow me to change a tire without a block of wood or a shovel.

Good thing I was prepared...
