Slight, or what they call thin, inner or outer wear is a sign of possible tie-rod play. (See first tire in Picture #1 called: Interpreting tread wear patterns.)

(Have it checked or jack up one side of the vehicle place jack stand under the vehicle for safety and then place your hands at 3 and 9 and shake the tire left and right while watching the outer and inner tie-rod on that side for play. Then do the same for the other side.)

A more aggressive, overstated, wear on either the outside or inside edge is more than likely a chamber problem. (See Second tire in Picture #1 called: Interpreting tread wear patterns.)

I cannot tell from the pictures – However, if you can rub your hand on the bad edge of the tire(s) (check for metal core showing before you do this) and it feels like (what I call) a tidal wave effect – you can have more than one problem.

In the above case: first check for front end play (most likely tie-rod play) and then check to be sure tire(s) are balanced. If tire(s) are balanced – most likely bad shocks and a tie-rod end has gone bad..

A bad tie-rod end allows the tire to move in and out slightly. That in combination to what I call the tidal wave effect is when a tire also bounces at the same time.
The bouncing can be caused by either a tire being out of balance tires and/or bad shocks which allow the tire to only hit the ground every now and then after running over bumps.
Keep in mind that the bumps at higher speeds do not have to be noticeable to a person to cause this kind of problem.
When a rotating tire hits, makes contact with the ground again, it will cause the cupping or tidal wave effect. Out of balance tires is the main cause – however like I stated before shocks can cause it too.

Hope this and the pictures help.

Sincerely, Tony

Marie and I are blessed to have had a 2nd chance to buy our farm.
Still hoping and more importantly praying to be able to build a garage.
Our 1970 Ultravan #520 has an Olds Toronado 455 in back.
