Will "cupped" tires wear back to normal if bad shocks are replaced?

Turns out I have bad shocks, and my tires are cupped pretty bad on the
inside. "Pretty bad" means they are very noisy and at higher speeds
the vehicle becomes a little unstable (probably exacerbated by the bad
shocks).

So if I were to replace all 4 shocks, check the alignment, and
continue to rotate the tires regularly, will they get any better?

Or are they now ruined?

Thanks.

Pretty much what you have is what you will have.

Cupped tires will not ever wear back to normal, rubber is rubber.Those
tires will do nothing but continue to wear on down.

Only hope is to have the tires trued. True, it may shave much *good
tread*, but ultimately you should get more total miles of service--that is
*IF* the cups have not cupped so deeply that it would take truing too close
to the wear bars. Very much similar to turning a rotor to remove grooves,
completely--may be better to leave a portion of that groove. One
difference, tho', the remaining portion of a trimmed flat spot usually will
immediately begin to wear flatter-and-deeper! s
*One note to add: I have used in the past a buffing method of truing
tires, which in my opinion is superior to traditional "blade-truing". Two
reasons: one is the buffing wheel tends to give a much better continuous
removal pattern than a blade, just by nature. Second is how often have you
seen the tech set up the blade-truer to properly follow the true profile of
the tire and allow it to self-power, as intended by its mfg? Many if not
most approach the tire w/the truer, spin the tire, and then manually crank
the depth of cut AND the contour they deem appropriate AND the speed of
travel across the tread--this contour continuously variable both in speed of
"crank-across" and perceived profile: must be they imagine it to be faster.
Doing so could result in a rough, huge, screw thread around the
circumference!*

....and not only that, the pounding will destroy your wheel
bearings, if you don't correct the problem soon enough

In a word no. They will not magically return to a perfect rire over
time. They will continue to ride like a washboard road. Just replace
them.

Thanks everyone.

I know I "shoulda known" but well... it appears I'm learning this one
the hard way.

The cupping that exists will continue to "creep" around the tire. IN
other words, the current high spots will wear down, but not
symmetrically so that the highest spots will slowly march around the
tire. It won't ever get back to a normal wear pattern, although it might
get slightly better than it is. Worst yet, it will continue to bounce
the wheels, putting a lot of wear on your new suspension components.

Or you could put 'em on the drive axle and do a few NASCAR/IRL style
victory burnouts to "round 'em down."

lol. As tempting as that sounds, I don't think the 109hp of my 2.5L
is up to the task.

I am going to replace the shocks and buy four new tires. These are
Sam's Club Goodyear Wrangler ATD2s. I received them as a gift from a
well-meaning and (at the time) kind and caring (now ex-) girlfriend,
who was concerned about my OEM Firestone Wilderness ATs. The
Firestones were great (recall bullshit aside) and I they were replaced
at 89K miles. They would have made it to 100K for sure, but were dry-
rotten all to hell.

I would normally just go to a real tire shop, but since someone else
was buying the tires out of the kindness of her now black and evil
heart, I accepted the gift of four new tires. Unfortunately these
Wranglers are complete garbage in just about every way that a tire can
be. I also hate that they can only be balanced or rotated by Sam's
Club- they explicitly state that if anyone else touches them the
warranty is void.

So... anyone got any experience with Dayton tires? They're made by
Firestone, right?

Thanks

Probably not ;-)

I've never had a Goodyear tire that I could stand. They're a huge tire
company and sell bazillions, so *somebody* has to like them, but every
time I've had a Goodyear tire, I've replaced it with a similar class of
tire from another brand that has been cheaper and better in every way.

Tire company ownership is about as complicated as auto manufacturer
ownership these days, and I have no idea bout Dayton. Firestone itself
is owned by Bridgestone now.

To each his own. Some years ago I bought the best Firestones I could get
for my Renault Alliance, and they were so bad after the Goodyears that
shipped with the car that I put the 48,000-mile Goodyears back within 100
miles. (More accurately, split them between the drive wheels of two
Alliances and put the slippery, noisy, bouncy, crappy Firestones on the
rear.)

Nothing but Goodyears for me since.

Got a friend who prefers Michelin, but he won't admit he's had more
blowouts than a man should have. (I once had one on an unknown brand tire
of unknown mileage/usage on my 1960 Pontiac.)

Does anyone still do this? I would have no idea where to go if I
actually wanted to have this done.

So went to a real tire shop. I bought 4 new Monroe Reflex shocks, and
4 new Dayton Timberline tires. My truck sure seems to drive
differently. The most noticeable difference is that the stopping
distance is much shorter now. I guess that means the old shocks were
letting the wheels bounce around waaay too much.

However, at low speeds I'm noticing a really intense "jiggling"
sensation. It seems to settle down quite a bit at highway speeds, but
around the 30-to-40 range it feels like I'm driving on a badly
washboarded road.

Could it be that the shocks are so new and stiff that the tires
themselves are compressing and bouncing excessively at each bump? If
that is the case, the shocks will 'loosen up' in a couple hundred
miles and all will be well, right?

An interesting thing, is that even at 35psi these tires look really
low in the front.


I'm trying to find a nice, smooth, lonely road to drive along at
different speeds, but around here all the roads are still wrecked by
the snowplow.


Thanks.

Does anyone actually shave tires anymore, save for race-centric places
that will take DOT-legal race tires down to "race depth" for you? I
don't know that I've ever seen that service offered at any normal tire
store.

Tire Rack has been doing it in the past. I guess they still do.
Siping is done at some Discount Tire places.

If they were mine, and they still were safe to use, I might move them
to the back wheels so I wouldnt feel it too much. I am near fanatical
about keeping good tires on a car.
