Rotating and Remounting Tires
Todd Kirby
mounted with the letters facing inward. Is it ok to have them re-mounted
with the letters out if they have worn to the point of having only about
half the tread left? Tread wear appears to be even all the way around.
Is there a specific rotation pattern I should request if I decide to
have this done or does it matter?
Thanks,

direction as originally installed. This would mean a side to side rotation
and/or front to rear rotation.
What I mean is: white letters inside on left front move to outside
on right front or right rear. This way the tire keeps rotating in the SAME
direction. If you flipped the left front over and put it back on the left
front with letters out, the tire would then rotate in the OPPOSITE
direction.
My knowledge comes from the many tires I went through while autocrossing.
Today I can run my hand over the tread surface of a tire and tell which
direction it rotated. If it rotates in the opposite direction it will
not get maximum grip.
I strongly suggest that if you don't have your own tire changer,
you mark where the tire is supposed to go, and stand there with the guy
doing the mounting. Not all of them have equal ability or an understanding
of the principle involved; much the same as where YOU work some people are
better at what you do and some are not as good as you.
Tire changers are built so tough these days, they can mount a tire dry.
This may not be good for the bead. Be sure the tire mounter uses a
lubricant on the bead AND rim and I don't mean spit or plain water applied
with a shop rag.
When you have them balanced, put a couple hundred miles on the tire and
get them re-balanced. Sometimes they have changed after flexing.

Depending on the tire construction, if they are radials, you may want
to switch them to the opposite side of the car when you remount them,
so that the direction of rotation stays the same. This is similar in
concept to the way some tire manufacturers recommend that you keep
radials on the same side of the car when you rotate them.

being always the same (with any tire) has to do with wear
and grip. I don't object that others disagree.
Ponder this:
If keeping the direction of rotation the SAME for better grip
and tire wear were incorrect, what is the worst thing that can happen?
(The tire has rotated that direction to start with for many miles)
versus
If reversing the direction of rotation were incorrect, what is
the worst thing that can happen? (The tire is no longer
rotating in the direction it has for many miles)
Have a great day!

No offense meant. For years, I have use the modified "X" rotation
where the tires cross sides going to the drive positions. The purpose
has been to reduce the noise that is generated by the typical wear
pattern of the shoulder blockes of tires with all-weather or
aggressive tread patterns. The wear pattern is almost always a result
of braking torque on the front tires and the rear tires tend to wear
more evenly as driving torque is much less than braking torque (I
understand this condition may not exist in a muscle machine). As far
as reducing "grip", it is my opinion that the grip is not
significantly affected because the weight carried by the tire patch is
simply moved from one area on the contact patch to another. The
reduction of grip to any extent may not be acceptable for some
purposes such as wet track competition. These conditions and tires
usually are not a problem on public roads.

modern tread technology and rubber compounds most tyres wear at the same
rate, on a serviceable vehicle, if tyre pressures are checked regularly. I
haven't done this for years and haven't had any uneven wear problems. The
benefits you get from doing this are minimal ,if any and hardly make it
worth wasting your time.

and cost me nothing. At $50-$150 per tire, that's a good deal. I've not risked
not rotating them now that prices are even higher. Have they improved THAT much
in just a decade?

the first Aircraft flight of the Wright flyer to walking on the moon in just
60 years. But getting back on track, computers have come along way in ten
years and computer aided designing and newer testing facilities have
dramatically improved tyre designs. Its a big market out there and anyone
who wants to stay in the race spends big dollars on tyre designing.Also the
list of natural and synthetic materials and methods used in the
manufacturing process have grown and improved remarkably. Having a
mechanically sound vehicle with sound suspension set ups, correct tyre
pressures for the driving conditions, which includes different suspension
loadings and correct stop start driving techniques will considerably prolong
tyre life, just rotating your tyres, is just not good enough!

You mean places like Tire America, or Firestone? I have yet to have my
tires rotated to the opposite side of the car by a dealer.

I bought my BF Goodrich all terrains from Costco, and I get free
lifetime balancing and rotation. However, every time I go have a
rotation done, I wind up arguing with some dumb kid that it is perfectly
acceptable to do a cross-rotation. Costco policy is to not do it. So I
contacted BF Goodrich and asked for their input. They sent me a brochure
from the Rubber Manufacturers Association that shows all the approved
rotation patterns, including cross-rotations, with the advice that for
uni-directional construction the tires should not reverse direction.
(duh)
I now have that stapled to my original sales receipt so that when I go
in, the proof that it is ok is right there. Cuts down on my aggravation
level.

Duh. Dealers live in the last decade and don't read the owners' manual. I
seldom visit dealerships for any complex procedure without taking my factory
service manuals along so I can show them how the guy what built my vehicle
intends it to be serviced. Now I guess I'll add "Rotate Tires" to my lst of
things dealers haven't a clue about.
Incidentally, I've caught dealers lying to me quite often about their work on
my car, because I know what is and isn't correct or even possible. Adjusted the
gain on my '85 Chevy Astro cruise control, my ass! It HAS no adjustment.
Re:" it's a personal choice I guess, but in the end I don't think it's worth

Orif you like saving hundreds of dollars on tires by doubling their lifespan.
Been there, many times. Don't rotate 'em ... throw 'em away in 20,000 miles;
Rotate 'em ... still using 'em at 40-50k miles. And at a quarter-million miles,
that vehicle's seen a few seats of tires. My big van's tires cost $150 each, so
doubling its tire mileage matters to me. Rotating its tires increased their
mileage dramatically. The 130-mph-rated unidirectionals on my Stang are not
cheap, and rotating (same side, of course) them extended thair lifetime
considerably compared to my first set that went unrotated.
Yep - it's my choice. So I choose to buy tires half as often.

Nospam,
I work at a dealership and I cross the rears to the front and put the fronts straight
back.
This is the GM service manual recommendation for non-directional tires.
Sorry your dealer techs can't read the manual.
Refer them to the service manual.

NEED to have the tires rotated very often. You're a fool if you don't.

don't know who told you tire rotation is unnecessary, but you are very
misinformed. I don't feel like arguing over though, so I'm done with this
thread. Have a good one.

first rotation is
the most important. As a technician that has been watching tire wear for over 7
years on
literally thousands of cars and trucks I have to say that your generalizations
are rediculous.
Radial tires curl under on turns causing scrubbing to take place on the outer
edges at
turns in excess of about 3 miles an hour, if you could drive in a straight line
everywhere
you go I guess you'd be ok.
Also many front drive cars will wear rear tires quite strangely and if you don't
keep them rotated they will start to "chop" and make horrible noise and begin to
shake the car.
As a person who services hundreds of cars per month and holds over forty
certifications
in automotive service I must say that tires do need rotated. Perhaps six
thousand miles
is a little extreme but that is what I recommend.
As for doubling the tire's life I doubt that is entirely accurate but I am sure
it is fairly close
to that.
Have a pleasant day and thanks for expressing your opinion.
