>" Three different tires are approved for use on HEMTT vehicles. Two of
>them work well with each other, but the other one is a loner.
>
>Here are the details: When you order a replacement tire using NSN
>2610-01-126-1576 from Note that the XZL is used on the M1070 heavy
>equipment transporter and the M1074/M1075 palletized load-ing system
>tractor. Just because the XZL can be used on the HEMTT does not mean that
>the XL or AT2A can be used on the HET or PLS. They cannot! The XL is not
>large enough for either vehicle, and the AT2A did not pass the use test
>for either truck. All three tires have non-directional tread, so it does
>not matter how they are mounted on the wheels. The tread can point forward
>or backward, even though the XL tread appears to be di-rectional.
>
>Some or all of these tires may rub against the HEMTT s front axle
>equal-izer beam during a hard left or hard right turn. Eyeball the beam
>for evi-dence of rubbing. There must be at least 1 inch of clearance
>between the tread and the beam when the wheel is turned as far as possible
>to the left and right. If you find evidence of rubbing, re-port it. Your
>DS shop must adjust the steering stop bolts to the correct clear-ance. The
>adjustment information is found in TM 9-2320-279-34-2. DS should note that
>TACOM has increased the clearance from 3 /4 inch to 1 inch since the TM
>was printed. TM 9-2320-279-24P, you get either a Michelin XL (16.00R20,
>load range J) or a Goodyear AT2A (16.00R20, load range M). Both tires can
>be used on the same truck without damage to the tires or the truck. It s a
>common practice to use all the same tires on a single axle, but it is not
>necessary. Both tires were tested together and are compatible on the same
>axle.
>
>Here s the word from Para 2-7 of TM 9-2610-200-14, Care, Maintenance,
>Repair, and Inspection of Pneu-matic Tires and Inner Tubes: "Minor
>variations of tread designs, as encoun-tered from one manufacturer to
>another, may be used providing the sizes and tire constructions (bias or
>radial) are compatible." There is another NSN shown in the HEMTT parts TM:
>NSN 2610-01-334-2694. This tire, a Michelin XZL (16.00R20, load range M),
>can be used on the truck only in a full set of eight tires. It cannot be
>mixed with the other tires, however, because its tread is not compatible. "
