Wheel Balancing

[WillJ]

Hi,

I have titanium wheel nut on my car, if I put a steel locking nut on the wheel, do you think the difference in weight will effect the balacing or is it near enough to the centre of the wheel?

Thanks

Will

How light is your car?!

1.3t I think it's a porsche944....

You think? how can you not know what your car is ><

if 1.3t is related to the engine size its more likely to be an 80s rx7 turbo which if you had no clue about cars and or were blind could look approximately similar to a 944.

Of course I know what car I have! - its a 1989 Porsche 944 S2 2990cc engine in guards red with Carerra Cup 1 wheels from a 968

The exact axle weight is is 1350kg..... I think.

Ahh 1.3 tonnes. I see.

I've done some googling and it appears the answer is yes, it could potentially be noticeable. Looks like you could be talking potentially 75g a wheel difference. Interesting thread here - http://www.lancerregister.com/showthread.php?p=225...

A practical suggestion... perhaps



1. On some kitchen scales, weigh the steel locking nut and one of the titanium nuts.

2. Subtract one from the other to establish the weight difference - call this weight difference dW.

3. Measure roughly, to the nearest millimetre or so, the radius from the centre of the wheel to one of the wheel stud centres - call this dimenesion A.

4. Measure the radius from the centre of the wheel to the position on the rim where the balance weights are positioned - call this dimension B.

5. Now some calculations. Determine the value of dW x A/B. This is the value of a balance weight, attached to the rim, that would have the same out-of-balance effect as using the steel locking nut

6. Compare the value of this 'equivalent balance weight' with the smallest balance weight commonly used to balance wheels (10g?). If the 'equivalent balance weight' is less than that, you can consider that the use of your steel locking nut will have negligible effect on the wheel balance.
