315's on a V6???

Re: 315's on a V6???

tire sizing has no effect on contact patch.... just fyi

So your saying a 165 would have the same amount of coverage as a 315?

Looks good, like I said 275's max, we don't have vipers.

the only way that can even begin to be true is if you're talking about tire diameter, not the width

i have 315s all the way around on my car front and rear... and its a v6 then again its a twin turbo vr4 too :P

Yes. physical contact patch is independent on tire width. Its weight of car divided by tire pressure. So, a 165 has the relatively the same contact patch as a 315, however a 315 would have more lateral contact.

QED

edit- to prevent a lot of flamming.

tire pressure = weight / contact patch

haha what u dont like the steam rollers on the back of my car? i c how it is lol

lmfao

no mike your's look great, goes well with blown transmissions!

the contact patch has two dimensions. how wide the tire is, and how flat the tire is.

Hmmm. Well since you SHOULD fill the tires according to the car mfgr's specs located on the inside of the door, one would think that with the same amount of pressure there SHOULD be more contact patch on a wider tire.

IE: using your formula, we can plug in some numbers:

27psi = 3500lbs / 129.62

Now if you put wider tires on there and the first two variables don't change. I would like to know how that is an accurate formula?

And even if this did hold true, why do we let air out of our tires at the track?

Not trying to flame, just don't understand the logic.

Re: 315's on a V6???

for explanation, refer to the last page of the june 08 issue of car and driver ( franz kafka's garage). Or it could be july... i'll check later.

but if contact patch is weight/air pressure then....

3500/27=129.62

decreasing the pressure to... say 25psi

3500/25=140

Are you seriously still trying to argue that tire size doesn't dictate contact? Can't you just imagine it in your head? Whatever dude. Go put bike tires with low psi in them and see how much contact area you have. And why would Top fuel dragster and funny cars have wider tires too if that was true. Wouldn't they want less weight for better ETs? Quit confusing the noobs. Noob.

I understand what you're saying.. and you're right in the fact that lowering your psi you'll have a larger contact area. But that would be only the difference between two like sized tires. And saying that a wider tread has nothing to do with increasing contact area and it all solely relies on PSI then that is just retarded. :slap:

^no need to get all personal and start throwin around the "n" word...anyone with half a synapse in their heads knows that wider tires have more contact with the ground

Smoke, I was just trying to be like you. hah!

Re: 315's on a V6???

^with "trying" being the operative word?


to onspeed, if filled to the proper PSI, you're trying to tell me that this



...has the same contact patch as either of these



..?

I mean, just trying to make sure that we're on the same page and all :rolleyes:

Re: 315's on a V6???

Lol yeah "trying" except I just skipped all the facts and went straight for the Duh part.
