1971 M818 Tire set-up

[818 Test Pilot]

Tires in back are the M818 Army NDT Thawk 11.00.20. Tires in front are the M818 Army Good Year Unisteel G17 11.00.20 tires. Owned many 4x4's over the years and always kept the same size tires all around. Does my M818 tire mix put a strain somewhere in the drive train? soon as i win the lottery gonna swap over two front good year radials to all NDT's. my biggest concern is how does the drive train make up for the worn tire diameter of rear tires compared to the front newer tires. understand in all reality all 10 tires are all 11.00.20 OIF1 88M

If the tires sizes are off a bit it may only effect it in 6x6 drive.

Since you didn't post tire sizes are they different diameter tires ?
I would avoid running a mix of bias ply tires and radial tires also .

Do you have a air shift transfer case or the auto locking sprag?

 

[818 Test Pilot]

just updated tire sizes

Do you have a air shift transfer case or the auto locking sprag?

I have no idea yet. Hear a puff of air when i shift to reverse. Have over 20,000 OTD (over the desert) miles w/5k jp/8 tanker but never got into the internal stuff and what makes it go fast

The M818 should have the air shifted sprag.

Yeah its fine, may not handle great with the mixed up set on it though
