Will you go away now?

Getting owned by your own link? Priceless.

Adding some actual experience to this thread:

I got an oil change at Toyota and they put my tire pressures back to the "driver's side door" spec.

Guess what? They filled it on the coldest day this week (in the morning) and are probably a bit higher right now just due to temperature. The car almost snapped away from me when getting on the throttle on my favourite on-ramp. Didn't happen the day before...

Tire pressures recommendations are just a starting point!

this thread just reminded me of this little gem

And the WINNER IS!

I just realised something. On the first page of text in the brochure:

And we're both on the same page which after Uber's little Michelin Pilot Sport Cup fail is just

Gonna start keeping a score board just for the pure entertainment value!

Eff that! A win is a win

I have these in a 225 45 17 on stock rims, as hard as I try I can't get the back to brake loose.
Could 1 cm make that much diff.? I wanna slide once in a while.

you need to turn traction and stability control off to do that...

Not the second sentence that you quoted.

I don't see where I misunderstood, a little help?
Here's how it appeared in the thread:

To increase the contact patch area. The heaver the load the larger an area you need on the road to provide grip. Put it another way, would you be comfortable driving a 1 tone vehicle with a contact patch of 1.6 sq"?

You get a larger contact patch for free with the SAME SIZE tires under a higher load at a given pressure. Having a larger tire at the same pressure doesn't necessarily give you greater contact patch area (also, greater contact patch area doesn't necessarily imply greater GRIP). In fact, greater contact patch area means greater deformation and greater heat into the tire, which is why you increase pressure for a given tire under high loads. It *reduces* the contact patch area but INCREASES allowable load.

Greater contact patch area does not equate with greater load-carrying capacity.

Greater tire volume does give greater load-carrying capacity at a given pressure, even though contact patch area is roughly the same vs. a smaller tire at the same pressure.

You could say it's the number of air molecules inside that determines the maximum load. Higher pressure means more air molecules and higher capacity. And, a bigger tire can contain more air molecules-and therefore has more capacity-than a smaller tire at the same pressure. And there's one other factor.

http://www.goodyeartrucktires.com/pd...tread_S5_V.pdf
A tire requires proper air pressure
to adequately carry the load placed on
it. The “container volume,” material
properties and inflation pressure determine
the load carrying capacity of the tire.

[wparsons]

We're not talking about extremely heavy loads here, we're talking about passenger vehicle tires.

If tire width doesn't matter, why don't you see BMW X5's driving around on 165's? The reason is because to get the contact patch area needed to support the heavy truck a 165 would need a very long contact patch (and a very flat looking tire), or extremely high pressures.

If you're talking about the difference between a 215 and a 225 on the same car, sure.

Take one car and two sets of wheels/tires. One set is a 215/45/17, the other is 215/50/16. Same tire make/model, so construction will be very similar. Both tires will have the same contact patch, and both have to support the same weight. Will the desired pressure in the 16's be lower because of higher volume?

Oh my god. I just, I don't even know.

Thank you so much.
