Tread Widths
compiled by Jefe, 12-26- 98

Factory tread with is not WMS to WMS. It's center of stock tire on stock
wheel to the same on the other side. It depends on offset of wheels and
several other factors. Tread width is usually narrower than WMS to WMS
because of the off set the center of tire is farther inboard than WMS. Use
this chart for comparison. I've seen both wide and narrow factory axled '81
CJ8's.

'88-92 Cherokee XJ 57"
'86-92 Comanche, 57"
'87 up Wrangler, YJ 58"
'93 up Grand Cherokee, ZJ 58"
Jtrucks are in the 64-65" treadwidth range.
That's pretty wide for a CJ8, (like about 5" wider each side). but with 8"
wide flares, you could cover the tires. Sure would be stable.
