Confidence in the Design
Design Proven by:
Reduced Scale Field Testing
24/85 R 35
European tests show improvementsover standard 100 aspect tires
44/80 R 57
North American tests validate 20% life
improvement over 40.00 R 57
Over 150 tires now in service
This gives Michelin over 500,000 hoursof actual
FIELD EXPERIENCE!

Confidence in the Design Design Proven by:
Internal Tests
Conducted at Michelins Earthmover
Proving Grounds - Almeria Spain
Over 800 hours of full scale testingconducted to date
Tests included bead/tread/casingendurance as well as thermal studies
Internal testing of the 55/80 R 63 shows the
tire meets (or exceeds) design parameters!
