Ice lug requirements (refer to illustrations):
Location on each shoe - Ice lug centerline is centered between track bolt centerlines. If not centered, then ice lug centerline is no more than 51 mm (2 inch) outside of the innermost bolt centerline. Refer to Illustrations 1,2, and 3.
Pattern in the track - At least one lug on every shoe. Two lugs per shoe are acceptable. Refer to Illustrations 4, and 5, and 6
Height - All ice lugs should be approximately the same height. Variable heights result in uneven track joint loading.
