Is this BS? Seems like BS to me, but who knows. It's raining outside so I can't really try this. Anyone wanna give it a shot?

Hmmm...

I still prefer my corner scales.

 

In theory this should work. It's simple unit conversion. It won't be perfectly accurate, but since PSI is pounds/in^2 and you are finding the area of the tire in in^2, the in^2 cancel out through the multiplication and your are left with pounds on that wheel.

I would still think that there are several other factors involved in this that would affect it, one for sure being how accurately you measure the tire pressure and the area of the tire, because you are dealing with a small number, so any error could throw you off a bit. However, it still seems like something is missing, but in theory off the top of my head i would say yes this works.

edit: i just thought about this more, and i would say yes for sure this works. But will only be as accurate as you are in your measurements.

 

^^^ +1 "there are several other factors involved"

 

May be useful but not accurate.

 

There are no other factors involved and this method will work; however, the accuracy will be very poor because of the method for finding the tire footprint (it wont actually be a rectangle) and the measuring equipment being used.

Edit: It will also depend on the tire tred you have and that is not accounted for in this method. Using slicks would help to be more accurate.

 

I prefer to just pickup my car and stand on a scale...then just subtract the diff. :P

 

 

^^ +1

That Method should work at well...

 

lol i dont think a minivan weights 2666 lbs

 

so if u have different size tire and width, that mean the car is heavier? lol

 

lol yup mine are now 205 45 16 and old was 185 65 14 so my car's weight increased by 15% even with Roats

 

just go to a trash dump and ask it you can use there scale. drive on the scale and that will tell you the EXACT weight of your car within .01 pounds

 

a peugeot possibly could be.

 

LOL! Now here is a man who is thinking: trash and EVO X ... poor association.
