Axle Weights
coozer - 15/7/08 at 03:02 PM

Do the two axle weights add up to the whole weight of the car?

On the rollers this morning I had 280kg at the front and 275kg at the back.

So, does that mean my car weighs 550kg????

no the car weighs 2 tons

did you included the middle axle?

go and have a coffee, thats 555kg BTW

190kg less than my buggy, must be the offroad tyres and that custom chassis

Was this at an SVA then Steve?

Not sure of the answer, it probably involves math.

But that's what I'd assumed!

Sneaky question Mike, it was indeed SVA this morning.... and, guess what??

No. The sum of both axles added together does not give the true total weight of the vehicle. Similarly, you cannot weigh yourself by standing with one foot on the floor and the other foot on the scales and multiply the reading by two.

so were does the difference in weight go then?

it doesn’t work when you weigh yourself because you have to shift your balance to stop yourself from falling over, hence you get a much higher reading than both feet together. Since the car has four wheels that isn’t an issue…

If the car is level (as per the scales are flat on the floor or the other half of the car is raised to the exact height of the scales surface) the weight should add up to be pretty damn close. As soon as the wheel heights are different it will be out.

Am I glad someone else has asked this. SO... If I were to use a weighbridge where the surface is level to the ground, put the front end on then the back end I should just about be OK????

It's just as Dale says. If the car is level the weight will be pretty accurate, although bear in mind that some weighbridges can have increments of 20kg.

I know Coozer SVA'd his car at Beverley and I also know that their scales don't weigh the axles whilst the vehicle is level. It's surprising how much weight transfer can affect the weights.
