Anyone know the answer to this. I've damaged the sidewall of one of the tyre
on my 850. Going to have to replace it. All the tyres on the car are
rotational, ie. have to be the right way round on the car turning in the
right direction. Question is, can I just get a njormal tyre to replace with,
or does it have to be rotational as well?
Thanks - Roy

It will have the be the same type and size, but not necessarily the same
brand. Matching the brand would be best, though. Using a mismatched tire
will interfere with the cars' handling.

I've never really understood the purpose of tyres which can only rotate one
way - what happens when you go backwards?!

I guess that there's a slight difference in their wet grip ability in the
two directions, but I doubt whether the earth would stop rotating if you
used one the wrong way round.

As far as mixing them with tyres which can rotate either way is concerned, I
can't see any problem. I have had the occasional 'rotational' tyre on my
cars in the past when I've needed a tyre in a hurry and that was all that
was available - and they always mixed ok with no noticable effect.

There ya go! The earth might start rotating backward! ;-)

To be safest replace it with the exact same tire that you damaged - this
will ensure the most predictable handling in an emergency... Are the other
tires in good condition? You might want to consider replaceing a pair of
tires, or all four if they are all a little low on tread.
 
if the tires have much wear on em at all then it will make no difference
what kind of tire you put on if its the same size directional tires
only make for better displacement of rain unless you slam on the brakes
at 60+ there is no way you would notice a difference even if you have four
different tires on the car as long as they are the same height and similar
width

BAD ADVICE YOU NEED ALL THE SAME PATTERN AND PROPER AIR PRESSURE
 
There is a huge difference in aquaplaning resistance when using directional
tyres on the wrong side as opposed to the right side. If you look at the
tread pattern you will notice it is a chevron. Whne the tyre rotates the
head of the chevron (in the center of the tyre)encounters the water first .
As the tyre continues to rotate the water is forced outwards to the edge of
the tyre for dispersal. If you run the tyre backwards the water is forced
toards the centre of the tyre - BAD IDEA!!!

Going in reverse is never a problem as the risk of aquaplaning in reverse is
pretty low.....

Manufacturers put those little directional arrows there for a reason....
best follow it!

Incidentally, in some countries using the tyres against the directional
arrow is illegal and it could invalidate your insurance...
 
Hi Everyone,

many thanks. Went to a local, good tyre supply place and got the guy to
reverse the spare tyre so I can use it to replace the damaged one. Replaced
the damaged tyre with a non directional, which is apparently perfectly legal
and in order and am using it as a spare. Makes sense really as now I can
replace any punctured tyre with the spare and not have to worry about
rotational direction. - Roy
 
john you sound like a crooked salesman - oftentimes uninformed and always

Replace the tyres of the left AND right side!

Hey I said the same tyres tires the same width right pressure ,not the other
nonsense which could get you killed .
 
Bob I was a professional driver for many years cheap tires are expensive as
are mismatched under or over pressured tires .To drive on mixed tires is a
stupid dangerous act in fact I would use the words criminal act .Back in the
old days when the garage used to do your tires \tyres I found my sports car
was all over the place a quick check of the pressures was scary stuff ,12 28
32 18 as I recall since then I do my own pressures .I am well informed as
once I had a council worker with mixed tires lose control and hit my car,
when I wasn't even on the road .
