Toyota Trucks: Tire pressure part 2

I've found it best to always use the placard on the vehicle as a guide for the
proper inflation amount. In your case, since Toyota wants 26/29 (regardless of
size in your case), that's what you should have. The tire manufacturer will
have a MAX PSI rating on the tire, which should not be exceeded. Usually 40 lbs
is the max for a passenger tire-some LT tires will handle more.

Dave.

Your on the right track with watching tire contact...as long as the tire
isn't too worn out already. Drop pressure down to about 35 psi. (front and
rear...keep rears same as fronts so tire wear will even out on rear before
you rotate tires back to the front) and observe tire contact. Forget about
the 26 & 29 psi the manual shows. Sure, it will ride a little better but
you'll be replacing tires all the time 'cause the outside edges (mostly
fronts) will wear out.

Go to your local tire shop. They will have a catalog listing the
details of the model of tires on your car, and the book will have a
Load/Inflation chart. Make a copy of the chart, and circle the line
for your size tires.

Go to a local truck scale - recycling center, landfill, truck stop,
large distribution warehouse, etc. Get axle weights for your car. If
you ask nicely, wait for all the truckers to get weighed and out of
there, and don't ask for a Certified Weigh Slip (which you don't
need), most scales will do it for free.

The Load/Inflation chart will give you the real pressures you should
use for starters. Those are the minimum pressures - you can always go
higher (up to the maximum pressure on the tire sidewall) for a firmer
ride and better tire wear & fuel mileage, but never lower than the
chart minimum figure.

And if you use the minimum, be sure to check the pressure every few
weeks to keep them from dropping to a dangerously low pressure.
That's when tires overheat and come apart.
