Home Industries Transportation Tire & Wheel Tire Testing Tire Proving Grounds Tire Buffing
Designed to enhance the understanding of tire performance across different tread levels, the Matteuzzi Tire Buffer machine at Treadwell Research Park represents a significant advancement in tire preparation for testing. It streamlines tire preparation and boosts the reliability of performance evaluations, aiding tire manufacturers and automotive engineers in creating superior products tailored to various driving conditions. 



One of the standout features of the Matteuzzi Tire Buffer machine is its automated profiling capability, ensuring precise tire preparation for grinding and buffing procedures. The machine delivers accurate and consistent buffing results, providing an evenly reduced tread tire  in much less time than on-road wear procedures. This precision allows for consistent sample to sample comparisons when looking at rolling resistance, wet or winter grip testing.  By offering a comprehensive analysis, manufacturers and researchers gain insights into how tire tread variances impact overall vehicle stopping distance, traction performance, and fuel efficiency or range.

Tire Buffer Capabilities 

  • Capable of removing rubber from new tires down to desired tread depths
  • Can accept 15”-22” tire sizes and 17.5-24.5” TBR sizes
    • Diameter Limit: 530-1400 mm/ 21 - 55"
    • Weight Limit: 100kg/ 220 lbs.
  • Can create standardized or custom buffed profiles
    • UNECE R117 – 2.0 mm target tread depth across the tire
    • Discount Tire Spec 4/32” – 3.2mm target tread depth across tire
    • Custom tread depth profiles can be used based on testing program goals
