TRUCK WHEEL ALIGNMENT 101<\/strong><\/h1>\n

by Betts Marketing Staff<\/p>\n

Proper semi truck wheel alignment is important for maintaining the overall welfare of your commercial vehicle. Poor alignment can lead to premature wear on your tires and bad fuel economy.<\/p>\n

A misaligned truck burns more fuel to go the same distance, wears expensive tires down unevenly instead of flat, and puts more strain on steering and suspension components that are not cheap to replace early. For fleets running tight margins, alignment is one of the few maintenance items that pays for itself.<\/strong><\/p>\n

If you’re ready to book a laser alignment at one of our 8 West Coast locations, you can schedule truck wheel alignment service here<\/a>.<\/p>\n

Otherwise, here’s what you actually need to know about truck and trailer alignment, what causes it to go wrong, and how to catch it before it costs you a set of tires.<\/p>\n

ALIGNMENT BY THE NUMBERS<\/strong><\/h2>\n

Misalignment costs real money in fuel and tire replacement, and the numbers add up faster than fleet managers expect.<\/p>\n

Based on a tractor running 65,000 miles a year at 6 mpg with diesel at $5.88\/gallon (the West Coast average), and a trailer running 60,000 miles a year, a properly aligned truck and trailer combination can save:<\/p>\n

Fuel savings: $1,274\/year
\nTruck tire savings (steer and drive): $1,268\/year
\nTrailer tire savings: $576\/year
\nTotal annual savings: $3,118\/year<\/strong><\/p>\n

These figures assume a 2% fuel economy improvement and 30% extended tire life after alignment, using $600 steer tires, $500 drive tires, and $400 trailer tires, with an 80,000-mile average life for steer and drive tires and a 100,000-mile average life for trailer tires.<\/p>\n

WHAT ALIGNMENT ACTUALLY MEANS: CAMBER, CASTER, AND TOE<\/strong><\/h2>\n

Most explanations of wheel alignment stop at “your wheels aren’t straight,” which does not tell you much.<\/p>\n

A real alignment adjusts three separate angles, and each one fails differently.<\/strong><\/p>\n

Camber<\/strong> is the inward or outward tilt of the wheel when you look at the truck head on. Too much positive camber wears the outside edge of the tire. Too much negative camber wears the inside edge.<\/p>\n

Caster<\/strong> is the forward or backward tilt of the steering axis. It’s what makes a truck track straight and return to center after a turn instead of wandering. Bad caster shows up as a truck that feels unstable at highway speed or pulls when you take your hands off the wheel.<\/p>\n

Toe<\/strong> gets blamed the least and causes the most damage. It’s whether the front of the tires point slightly in or out relative to each other when viewed from above, and it’s the angle most responsible for fast, uneven wear across the whole tread rather than just one edge..<\/p>\n

A proper alignment measures and corrects all three on every axle, not just the front.<\/p>\n

SIGNS YOU NEED A WHEEL ALIGNMENT<\/strong><\/h2>\n

These signs (below) are indicative of potential issues with wheel alignment. It’s essential to pay attention to these signs and have your vehicle inspected by a professional if you notice any of these symptoms to ensure your truck or trailer maintains proper alignment for safe and smooth driving.<\/p>\n
