Aligning with the Hunter ProAlign HD System
We use the Hunter ProAlign HD system, cutting-edge technology known for its precision, to provide superior alignment service for heavy trucks, semi-trailers and recreational vehicles.
With this professional-grade equipment, we detect problems often invisible to the naked eye — and you get back on the road with complete confidence.
Our duly certified technicians provide rigorous interventions that extend the life of tires, improve handling and reduce fuel consumption.
A clear report is given to you after each intervention, and all data is kept in your customer file for optimal monitoring.
Why an alignment?
Tire alignment is an essential preventative maintenance measure for your heavy-duty truck, semi-trailer and RV. This is done to prevent premature tire wear, obtain better handling and even save fuel!
When to do an alignment?
The most common issues that indicate an alignment is necessary include:
- Tires become off-center
- Less responsive steering
- The steering wheel vibrates
- Steering wheel does not return to center after turning
- Difficulty steering the truck
- The truck pulls in one direction
- The truck turns left/right when braking
- The truck seems unbalanced
- The tires no longer grip the road like before
