Interesting, I dug up something a couple years back I thought, hmmm...
I will look some more to see if I can find it again..

The 'silly' spare is for emergency use and for sure if you get caught on
the highway doing 100+ with one and something happens you will get a
ticket. They have a lower speed stamped on them.

I guess the cops and insurance could have been giving me an outline of
what 'could' happen if they subjectively decide mis matched tires make
it my fault period like they stated.

Calling a 'fault' on an accident doesn't always have any basis in
reality.

Both the police and the insurance inspector told me the same thing at
different times and places. One of those hidden 'gotcha's' maybe. They
both commented about the number of tip overs and crappy tires on 4x4's
so maybe it is a subjective thing?

Sounds like a case of not the whole story, Mike. How can they make an
faulty equipment claim if the tires meet the manf. specified
requirements (right size, same rated size, in acceptable condition,
brand not specified)? I could see some basis for different tires on
the same axle, but I can't see any safety issue even if the tire sizes
are different on the front axle vs. the rear axle so long as they meet
the manf. spec. The way you put it, you would be required to change
tires as a set - and what's the difference between a 2WD and a 4WD if
the 4WD is not engaged? I've seen tickets written for mismatches
sizes on one axle but never for a misnatch axle to axle.

Sounds like a case of not the whole story, Mike. How can they make an
faulty equipment claim if the tires meet the manf. specified
requirements (right size, same rated size, in acceptable condition,
brand not specified)? I could see some basis for different tires on
the same axle, but I can't see any safety issue even if the tire sizes
are different on the front axle vs. the rear axle so long as they meet
the manf. spec. The way you put it, you would be required to change
tires as a set - and what's the difference between a 2WD and a 4WD if
the 4WD is not engaged? I've seen tickets written for mismatches
sizes on one axle but never for a misnatch axle to axle.

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.
