Tires vs Speed

[ruski]

Do tires wear out sooner the faster you drive? I am not talking curves. Just straight Florida highways.

[axles of evil]

interesting question, i dont think so, miles are miles and a single rotation is a single rotation.

HOWEVER the added heat from the faster rotation may contribute to faster wear.

[Rob@WretchedMS]

Never really thought about that,

I'd have to go with no, but you got me on that one.

[cobol]

im going to say yes, mainly because the other people said no.

my theories.


Added force on the tires in heat, pressure, and breaking at speeds will cause more wear.
the faster an object is moving the more damage is created by objects in its path. So all the rocks and rough concrete would be pounding on the tire at a higher speed, so more force.
Down force at higher speeds would push the tires to have more contact and thus wear more.
heat blisters.
creates more force on impoper alignment, so amplifies the tire wear caused by alignment problems.


back to reallity, i dont think any effects of speed would be enough to make a claim either way. Although the veyrons tires are only good at two hundered whatever MPH for like 50minutes, but the car would run out of gas in 30min IIRC.

lol, sounds like something I would say...

[dclaw_fantum]

Yes...

The tire is flexing with speed of rotation (look at the tires when a nitro dragger does a burn out), heat and vehicle speed too.

The part of the tire that is contacting the road is actually not moving when in contact with the road due to the physics of friction. So, everywhere but the area of contact of a rotating tire is going at X RPM's and the contact area is going 0. (Again see dragger burn out, noticable tire sidewall twist under initial torque.)

The added heat from the increased friction from speed aids in wearing the tire faster. Heat = rubber getting softer = easier wear.

Also, running tire shine will actually help hold heat in the rubber of the tires, again, aiding in the faster wear of the tires.

Well, i dont have any empirical evidence, but i would guess that tire wear faster at higher speed, if for no other reason than they run hotter. Not that thats enough to slow me down.

The answer is absolutely YES. There have been studies on the subject. During WWII there was even a resource conservation campaign that resulted in reduced speed limits to reduce both tire wear and fuel consumption as Rubber and Oil were both "strategic materials" and desperately needed for the war effort.
