2. Do I need to get a
spare and will it fit in the factory location?
Getting a spare is not necessary, however, if the
spare is worked into the rotation pattern, then the set will last
that much longer. It's not a good idea to leave the spare under
the truck and never run it, as the rubber will dry rot and the spare
may not be any good when you need it. In most cases, the 225/70R19.5
is the only size that will fit in the factory spare location, although
some 245s will fit. We recommend getting a spare if it will give
you peace of mind, or if you plan on traveling to Alaska or Mexico.
