Abstract: A method and system monitor a plurality of operating parameters for a tire over time during usage of the tire as the tire is exposed to actual operating conditions. The system and method may also determine a tire health parameter for the tire that provides an indication of the condition of the tire based upon the data collected for the tire over time during usage of the tire. The plurality of operating parameters includes, in the least, a temperature associated with the tire during usage of the tire and a duration of usage of the tire.

Abstract: A new pneumatic radial ply truck tire 10 for use on steering axles has a tread 12 with a pair of centerline grooves 14 and a pair of shoulder grooves 16 that divide the tread 12 into a pair of shoulder rows 24, a pair of riding rows 26 and a center row 28. Lateral grooves 20 divide the rows into block elements 22. The centerline grooves 14 and shoulder grooves 16 have top, middle and bottom potions 30, 32, 34 and 36, 38, 40. The top portions 30, 36 have straight sides 42, 48 that are angled at top angles A1, A2 respectively. The middle portions 32, 38 also have straight sides 44, 50 that are angled at middle angles A3, A4 respectively. To provide the grooves 14, 16 with a general V-shape, it is preferred that the middle angles A3, A4 be greater than their respective top angles A1, A2 respectively. The bottom portions 34, 40 are U-shaped and have bottom widths X1 and bottom depths D1, D2 respectively.
