Tire selection
When replacing a tire, use a tire of the same size
and construction, and the same or greater
maximum load as the originally installed tires.
Also, on four-wheel drive models, all the tires
must be the same brand and have the same tread
patterns.
Using any other size or type of tire may seriously
affect handling, ride,
calibration, ground clearance, and clearance between
the body and tires or snow chains.
Check that the maximum load of the replaced tire is
greater than 1/2 of the Gross Axle Weight Ratings
(GAWR) of either the front axle or the rear axle,
whichever greater. As for the maximum load of the
tire, see the load limit at maximum cold tire inflation
pressure mentioned on the sidewall of the tire, and
as for the Gross Axle Weight Ratings (GAWR), see
the Certification Label. For details about Certification
Label and sidewall of the tire, see pages 615 and 660.
