Mismatched tire brands
(Sorry this is so long)
No, that's not what I'm saying at all Mike. Just pointing out the legal
differences between the US and someone who said you can go to jail for mixed
tires in Canada. I investigated tons of accidents during my years in law
enforcement. Tons. I was a certified accident investigation trainer as well.
I never found mismatched tires to be the culprit. Bald tires on ice a
couple of times, steel belts showing then the tire blew out a couple of
times, but that's it, and those were the fault of the owner.
Again, I don't condone mixing up tires, I'm just saying that some of the
responses were a bit overboard in what might happen, and that other than
with blowouts and severe under-inflation, (which causes a blowout due to
heat like with the Firestone/Explorer fiasco) tires seldom cause and
accident, but they can reduce your ability to control the vehicle IN an
accident, or in extreme conditions. People go overboard trying to make a
point, just like when I tell people I ride a motorcycle, they ALWAYS know
someone killed/maimed on one, or know someone who knows someone who was
killed or maimed on one.
Regarding the gent in the other newsgroup, I read the post, but disagree
that mismatched tires were the only cause. LOTS of things can cause
fishtailing in snow, it is snow, after all. The rear of that vehicle weighs
much less than the front, and it WILL come around the front on acceleration
because the front weighs more, and with the "plowing" of the front end due
to snow and weight, the front has more rolling resistance. The rear tires
will take the path of least resistance, to the left or right of the front
end. Mismatched tires will only create secondary problems, but won't CAUSE
the problem, unless WILDLY different.
Todays SUVs may be more susceptible to differences in tires, but the laws of
gravity and physics hasn't changed.
I would venture a guess that when you "damn near put your Pontiac Wagon in
a ditch", you were merely driving too fast for conditions. The tires didn't
cause that, you did by driving beyond your tires ability to maintain
adhesion to the road. There are totally different dynamics going on front to
rear and side to side on a turn. Weight, speed, traction, road conditions
and driver ability all playing a part.

I think it's important to appreciate just how "mismatched" these can be.
Two tires of the same type worn as slightly different rates aren't the same
as putting two entirely different sizes (width and/or height) on there.

But if you're in a ligitation-happy situation who'd buy them? And what
liability could you get stuck with since you knowingly sold them to someone
because you knew they couldn't be used "properly"?

Re: Mismatched tire brands
I think there are 2 separate questions here:
1) Is it the right thing to do?
2) Is it legal?
Then question 2 becomes legal _where_ as I am sure there are differences in
jurisdictions....
On my TJ and the YJ before that I always keep the same 4 tires all around.
On the Sienna I go by axle with no problem. - I stay with the Michelins, but
I had put a set of X-Ones on and did not like (won't hold air or balance)
them as much as the regular X-Radials so now there is the newer X-Radial on
the front and the vestigial X-Ones on the rear until I can finally get them
to wear out. No problems seen.
I also suspect that front drive pull cars are more forgiving on this than
rear real drive push cars.

Re: Mismatched tire brands
I think there are 2 separate questions here:
1) Is it the right thing to do?
2) Is it legal?
Then question 2 becomes legal _where_ as I am sure there are differences in
jurisdictions....
On my TJ and the YJ before that I always keep the same 4 tires all around.
On the Sienna I go by axle with no problem. - I stay with the Michelins, but
I had put a set of X-Ones on and did not like (won't hold air or balance)
them as much as the regular X-Radials so now there is the newer X-Radial on
the front and the vestigial X-Ones on the rear until I can finally get them
to wear out. No problems seen.
I also suspect that front drive pull cars are more forgiving on this than
rear real drive push cars.

Re: Mismatched tire brands
Turns out the tires the gent in the other group bought were 235's with
one 215 tossed in..... I figure when he matches the tires, his Jeep
will run 'normal'.
When the Pontiac with the miss matched brand tires slid out on me, I was
doing the posted speed on a highway ramp I drove every day back then.
It was also the favorite place in town for the cops to hide with their
radar so I 'know' I wasn't speeding....
Here in Canada, if you go out and kill someone in an accident and you
have mismatched tires on, you are driving what is considered an 'unsafe'
vehicle and you could go to jail for that.
That is one good reason Dealers and tire shops now a days won't install
mis matched tires and a good reason to think twice about doing it.
There is serious liability involved.

When the Pontiac with the miss matched brand tires slid out on me, I was
doing the posted speed on a highway ramp I drove every day back then.
It was also the favorite place in town for the cops to hide with their
radar so I 'know' I wasn't speeding....
Here in Canada, if you go out and kill someone in an accident and you
have mismatched tires on, you are driving what is considered an 'unsafe'

Re: Mismatched tire brands
Turns out the tires the gent in the other group bought were 235's with
one 215 tossed in..... I figure when he matches the tires, his Jeep
will run 'normal'.
When the Pontiac with the miss matched brand tires slid out on me, I was
doing the posted speed on a highway ramp I drove every day back then.
It was also the favorite place in town for the cops to hide with their
radar so I 'know' I wasn't speeding....
Here in Canada, if you go out and kill someone in an accident and you
have mismatched tires on, you are driving what is considered an 'unsafe'
vehicle and you could go to jail for that.
That is one good reason Dealers and tire shops now a days won't install

Re: Mismatched tire brands
Turns out the tires the gent in the other group bought were 235's with
one 215 tossed in..... I figure when he matches the tires, his Jeep
will run 'normal'.
When the Pontiac with the miss matched brand tires slid out on me, I was
doing the posted speed on a highway ramp I drove every day back then.
It was also the favorite place in town for the cops to hide with their
radar so I 'know' I wasn't speeding....
Here in Canada, if you go out and kill someone in an accident and you
have mismatched tires on, you are driving what is considered an 'unsafe'
vehicle and you could go to jail for that.
That is one good reason Dealers and tire shops now a days won't install
mis matched tires and a good reason to think twice about doing it.
There is serious liability involved.
