Take a hard look at the tread on the Goodyear MTR that were on the
front . Examine the tread near the 'inside' margin and see if there
isnt a wavy pattern in just the 'inside' area of tread. If so you have
probably a loose track bar or trackbar frame mount, etc. ... or even a
worn out steering damper.

Ditto on the mismatched tires on a 4X4, besides being illegal in most
places the strain that this mismatch (size) will put on the drive train
can be severe resulting in exptreme differential pressure, rapdily worn
diff. bearings, etc.
It s a good practice to rotate 5 tires to keep them all at the SAME
diameter ... and if you ever 'lose' one you will have an exact size
spare.

Thanks for the tips. The Toyo's were the ones on the front, thier wear
appeared normal. A spin and balance cured the problem. All 4 tires are
215/75R15, the rears have 5k miles, the fronts less than 200 miles.

Thanks again..
