What tire.. Width?

Great thinkers in all disciplines seek the single unifying answer. I will take the cowards way out and the answer is five, sort of a Hitch Hikers Guide to the Galaxy way out.

So the answer is 42, but what are the units?

420 section width tires..... I can probably get those under the rear of the C10 but they ain't gonna fit Tubey.

IMHO, the takeaway from the rule about "wheels the same width as the tire" isn't that you need narrower tires -- it's that you need wider wheels. :)

In reply to codrus (Forum Supporter) :

That's why I have 205s on 8" wheels

Yes it would take a book to answer these questions. I was hoping for cliff notes. For future referance.

So, to our future selves, the consensus is as wide a wheel and tire as budget and rules allow.

So what happened to Acura at Le Mans?

I question this.  While I've never done a scientiffic test this is inconsistent with my experience and I can't wrap my head around why this might be the case.  I would think that all else being equal (which is unlikely to be the case) it woudn't matter which way the contact patch was oriented.

It depends on sidewall design and tire deformation under torque.  Although it makes sense that contact = contact no matter what shape it is, when you mash the pedal, a skinny tire will tend to pull the leading edge of the contact patch toward the ground more than a wide tire, if for no other reason than a wide tire's tread center is further away from the sidewall than a skinny tire.

the width would be half  of twice the width if you measured it with a string

if it was a square, it would be the same as the height, or the depth if it was  a cube.

Not wide enough is the usual answer, but it depends if it wasn't wide enough to begin with.

Otherwise, the answer is 195mm
