I haven't had too much time to look at the location of spares but some seem to be in impossible spots. "Under the bed": so the driver scootches on his back (because who brings along a mechanics dolly, plus it wouldn't roll on gravel anyway), loosens the lug nuts, and the spare falls on him. Bad enough the weight of a car tire much less the weight of a truck tire! KM> And I have a spare spare I found by the side of the road, also KM> never used. It's even the same tire! Must have finally loosened from when that other driver we trying to get it! ...BTW, you didn't happen to find an empty storage space on your truck, did you? It was your tire dummy!

I'm thinking those truck tires aren't all that easy to wrangle. A car tire can lift into position; maybe two muscled people can lift a truck tire.

KM> Every vehicle is rated for maximum tow capacity. That doesn't KM> mean ANY towing is a good idea, just that it's theoretically KM> possible to do so safely up to that limit. Probably safer to think of going up to two-thirds of the rated capacity rather than 110% of the rated towing capacity. KM> As the old tagline went: KM> .. Optimist: Yugo owner with a trailer hitch.
