Yesterday, my hubby and I were out running errands in the pickup. We somehow ran over a big piece of metal and blew out a front tire. No problem, we're not totally mechanically incompetent. We get the spare tire out, loosen the lug nuts, jack the truck up...and it's just barely high enough to pull the flat off. But we were nearly 20 cm too low to put on the spare. Even with a block of wood under the jack, there wouldn't be enough clearance. I can't believe we had to call a tow truck to lift up the front of the truck so that we could change the tire! The tow truck driver said he sees it all the time - the jacks that come with trucks often don't lift high enough. What a waste of an otherwise beautiful afternoon !
