Dennis,
I know for many years, some people have said not to rotate radial tires so
they will be rolled in reverse directions. That may have been particular to
fabric belted, I don’t know. I’ve always done the front-rear crossover thing
on all cars I’ve owned, but all have had steel belts. I’ve never experienced
a problem with the full-rotation, including spare, strategy.
I have experienced a slight pull when a different brand was on each front
wheel. And, the old Firestone 720s used to come apart now and then, leading
to odd behavior just before the terminal event. When all the tires are well
balanced and treads are worn evenly, I’ve had no problems. But, I haven’t
driven over 100mph much either! I’d like to see the factory manual when I get
it – these are the same folks who picked Lucas for electrics, right? {:o]

My factory owners handbook, on page 52 under Tyre Replacement, recommends:
“No attempt must be made to interchange tyres from front to rear or vice
versa as tyre wear produces characteristic patterns depending on their
position and, if such position is changed after wear has occurred, the
performance of the tyre will be adversely affected.”
I took this to mean “unique adapting wear characteristics” of each wheel in
independent suspension, and not to rotate tires. However it may only mean in
the case of severe wear. What is the general consensus on rotating tires?

I’ve experienced this too, with other tire brands. I’m sure most everyone
knows this, but in case not – when rotating the tires, say every 10,000km,
always bring the tires from the rear straight to the front, so they continue
to roll in the same direction; flip the fronts before moving them to the
rear,
so they learn a new direction where it matters less. Also, if there’s a
real
spare in the trunk, use it on a rear wheel first and reload the trunk from a
front wheel. Also, as mileage approaches the tires’ half-life, invest in
reversing them on the rims. This is especially helpful on front-drive cars,
which wear the inner tread most.

Oliver: I may have the answer for you. In the last month or so I noticed
that my 84 Sovereign was pulling to the right, and my hand was getting

keeping it straight. Since we were about to make that trip to California,
I
stopped in to see my alignment man. He said that the very FIRST thing to
do,
since the car had Pirelli tires on it, was to swap the front tires left to
right. It seems that some radial tires, Pirelli particularly, but not
exclusively, have a “belt shift” sometimes. Not dangerous but it DOES
cause
this problem. Well, I did the swap, and the car now pulled to the LEFT!!!.
Solution? I simply put the spare on instead of the offending tire, and the
car tracked straight and true, and continued to do so all through our 2100
km. trip. Honest mechanics are worth a lot, and instead of selling me an
alignment, this fellow told me the truth. So now my spare is truly a
“spare”, to be used only in emergencies. Try this on your car before
resorting to a mechanic fix.

Subject: [xj] My 86 SIII wants to turn left
Hello all - my SIII has developed a marked enthusiasm for wanting to go
left. I think it might be the left front tire seperating, but before I
get
them all replaced (as I’ve been planning to do for weeks) is there an XJ
specific complaint that might be causing this - ie it’s not the tire at
all?
TIA!
