The major/minor wheel vehicle is an experimental vehicle that employs the Terrastar locomotion concept. A previous test program was conducted with the vehicle equipped with 16x14.5-6 tires, whereas in this program the vehicle was equipped with 20x14-10 tires. The main purpose of the program was to determine whether the larger tires improved vehicle performance. Performance parameters were go or no-go, one and 50 passes, in soft soil; maximum water speed; water exit; and vertical step height capabilities. Mechanical breakdowns reduced considerably the amount of testing compared to that anticipated at the start of the program. Comparison of the results of the two programs shows that the larger tires reduced one-pass soft soil vehicle cone index from 8 to 5 and increased maximum water speed from 2.8 to 3.1 mph. Water exit capabilities were at least as good with the larger tires. A vertical step height of 22 in. was mounted with ease with the 20x14-10 tires. Step height tests were not attempted with the vehicle equipped with the smaller tires. (Author)
