The Autel MaxiCheck Pro is a powerful diagnostic tool for automotive professionals. One of its key features is the ability to perform tire size calibration, crucial for maintaining accurate speedometer readings and ensuring proper vehicle handling after changing tire sizes. This article compares the Autel MaxiCheck Pro’s tire size calibration capabilities with those of the Snap-On scanner, based on a user experience with a 2008 3rd generation truck.

Autel MaxiCheck Pro: TPMS and Tire Size Adjustment
The Autel MaxiCheck Pro offers a user-friendly interface for accessing tire pressure monitoring system (TPMS) and tire size adjustment features. Navigating to “Hot Function” and then “Tire Pressure” provides access to these settings.

A significant advantage of the Autel MaxiCheck Pro is its ability to accommodate both heavy and light load TPMS settings for vehicles equipped with this feature. This contrasts with the Snap-On scanner, which only provides a single setting. This flexibility allows for precise adjustments based on the vehicle’s load condition.
Autel MaxiSys displays both heavy and light load TPMS settings.
The Autel allows for adjustments within a specified range, typically between 28-80 PSI, depending on the vehicle. In the user’s case, the heavy load limit was set to 40 PSI, triggering a warning light at 34 PSI. The light load setting was adjusted to 28 PSI with a warning threshold of 22 PSI. Importantly, 28 PSI was the lowest possible setting allowed by the system.
