Left side tire wear/learned something new

[BRIO]

Forgive my ignorance if this is common knowledge...

I just noticed today that the left side of my tires are more worn than the right. I thought maybe something was out of alignment but no. As I was looking at this I started thinking that maybe was the result of the Coriolis force. According to a quick google search this phenomenon is due to the crown of the road and the fact that left turns are faster. I never knew.

Naa, I think it's probably the Coriolis force..

From traveling west in a Kansas south wind. Just ask anyone that did it last Sunday from Cedar Vale.

It could be your riding stance.

 Yeah , in England and OZ tires wear faster on the right side . Of course , since they are upside down in OZ they must mount their tires upside down to compensate .

Or offset the rear tire by between 5 to 10 mm. .................

Do you have to change that off set to the other side when you change direction?

 Only on German motorbikes , every other brand must be shifted in reverse and ridden in a counter clockwise direction for three complete revolutions before setting off

Now now ............. Lettuce not get silly.

 Dusty

No no .......... On Germanic motorbicycles you ride backwards
To the Banksiamans place and ask the Dropbear to reverse the
Tires and stamp his left foot three times.
It's all good!

quit sitting side saddle on the left, switch it up and sit side saddle on the right

 Professor Irwin Corey was correct. But you should have known!

I'm sure we have some ex artillery guys on here who can explain the Coreolis effect firing to different points of the compass.

Well, I *told* you that what caused it, but would anyone listen?? Noooo.

Why are left turns faster?

[oldbike54]

Why are left turns faster?

 Maybe because the radius on left handers is greater requiring more tire rotational speed to maintain a certain speed . Or maybe because he just goes faster in left handers because , well , he learned to ride in a counterclockwise state

Why are left turns faster?

Race cars go left.  If other ways were faster they'd go them.  Sheesh.  Some stuff is just ovious.    <--- lefty

[Dukedesmo]

Yeah , in England and OZ tires wear faster on the right side .

Particularly when 'roundabout surfing'...   

[Penderic]

Moto Guzzi should have reversed the crank rotation in the English and Australian bikes to help compensate for that.

Now that wasn't very well thought out was it Dusty ? Thanx for the reference to you know what, but I'd just like to point out that although I can see clearly the humour in yours and others posts it still remains that no one, including the luminaries have got a damn clue. Plenty of witticisms, but ill conceived and baseless theories a abound, let it be said though that I've run out of ideas too.

[redrider]

Left turns faster? Evolution is the culprit. Tens of thousands of years ago we were hunters and mostly right handed. Injure the right arm and the family starves. We are more likely to be cautious leading/turning to the right. Hold the shield on the left, sword on the right. Sinister side. Sinestro. Right hand of god. Coffee good.

 The real answer is simply the slight banking of most roads , but nobody wanted to believe that , so you get silly answers .

Where's Panhead when we need him (RIP)  Us tankers didn't have that problem  :)

I think you're over thinking it...

Have you got photos to post?

If the wear is slightly off-center, and you ride mostly straight 2-lane blacktop, then thank the crowned roads.

If you're wearing your tires well to the left side, then it has to do with your riding style and the roads you're riding.

Some people are more comfortable turning one way over the other and will push harder when turning that direction.  Maybe you like hard-charging the lefts because you have a good sight line?  Maybe you have more lefts on your rides?

Maybe you sit wonky on your bike and ride down the road with a few degrees of list?

The answer is probably "some of all of the above".

[vstevens]

Coriolis effect?  Isn't that responsible for ocean and air currents due to the spinning of a spherical Earth?  Unless, of course, those flat Earth guys have it right!

Oh all right then. Of course it's the crown in the road.

I always seem to attack left turns harder than right - hell, who am I kidding, no question that I do.

Some might say it's a reflection of political leanings on my part but lefts in cars or on motorcycles are just more comfortable to execute aggressively.

This, I see in the more greatly diminished "chicken strips" on the extreme left.

General extra wear just off center? Yup, road crown.

Too though, there's this... What side do you carry your wallet on? Maybe time for a "man-purse"?

I was an accident investigator here in London for several years and the  effect of the road 'camber' can be quite noticeable.


The next time that you see straight (skid to stop) skid marks, as opposed to curved ones (striations where the wheel is still rotating around a curve ie drifting)
Check out where they head.
Invariably they take a straight line towards the kerb/ footway, and thats because of the effect of the surface camber.   

[Guzzistajohn]

In a predominantly Jewish area it's known as the coriolis Schwartz effect

[cruzziguzzi]

It could be the "Cary Elwes effect"... A continuous draw to drive Westley.

"... The battle of wits has begun. It ends when you decide and we both drink, and find out who is right... and who is dead."

Overstated, sure, but what are ya gonna do?
