Tire Inflation
Posted by Tim on May 10, 2006
On a fire apparatus ladder truck, front axle wieghs 19240#. The tire is a Goodyear, G286-425/65R22.5 (LR/L). Currently we are maintaining 105psi. Could we safly lower to 95 to 100 psi?
According to the load / inflation tables for this tire size, you may safely lower your inflation pressure to 100 PSI assuming the load is equally distributed between the two tires on the steer axle. At 100 PSI, this tire will carry 9790 lbs of load.
WEAR PATTERNS
Posted by Tim on May 10, 2006
I read an article that described wear patterns and probable causes and solutions. I can’t remember where I saw it and would like to have a source of similar information. Any suggestions; website recommendations?
By far, the best information on tire wear patterns is found in the ATA's Technology and Maintenance Council (TMC) "Radial Tire Conditions Guide" available from the TMC website as follow: http://www.truckline.com/aboutata/councils/tmc
