Actually if your tires have some dust on them you can probably get a more accurate area measurement. Remember the old saying you get what you pay for. I don't know what you have to pay for paper and a pencil LOL¬  :D

It is handy to know from previous knowledge what your car weighs so that you can have confidence in the method the first time you do it. I did this with my pickup when I had a slide in camper. I just did it with a tape measure and got a very rough estimate of the area calculation then did the math. I can't remember exactly but I think I was about 10 to 15% high with this method when I checked at the local scrap yard scales.

most drivers at local short tracks have a schedule of maintenance for their car, and do keep chassis setup records, if you don't your car wont be competitive and you will burn up a set of tires in no time. or you can be like a driver i know from peterborough who pays someone $250 per week to do his setup and maintenance and thinks that 2 or 4 new tires per week is the answer. i think i will save my money, do my own work on my car and feel better knowing i am learning something while still having fun

I heard that grain scales will work too if you don't have the cash to buy electronic ones.

if you ever come across a set of mail scales they work well plusthe car is in the air already to work on. only downside is they take up alot of room.

 ¬  ¬ The most important thing you have to remember about scales, and I say this as an Electrician not as a racer, is maintenance and calibration. This is especially true if you are using 4 different instruments as you would when trying to get your weight distribution right as those on here would be trying to do. All four should be calibrated to the same standard every time you use them. Scales can be very finicky. Bumping and dirt and temperature can affect load sensors. Portable scales are especially prone to going out of calibration due to the nature of the use. If one of your scales is off 10 or 20% you won't find out until you run off into turn one the first time. Grain and mail scales, especially the older ones, use a system of weights and cables which can vary from instrument to instrument which makes it hard to get them to jive with each other. Electronic scales are by far the easiest to maintain and calibrate and get any two or four given instruments to read the same.
 ¬  ¬ When you purchase any instrumentation they should come with items for calibrating the instrument and instructions that have to be followed in order to ensure many years of use and proper readings.

I should add that 'calibration' is only something you do if you know a given instrument is out of whack. I should use the term 'check' with a common item of a known weight. Then 'calibrate' if the scale is off.
