Ideal Formula = Rim size -10/weight of rim

[Kelpie]

1. I wonder whether there is a specific weight ratio between Rims and Tyres? For example, a 7 kg rim should be matched by a tyre weight of not more than 7kg.

 

3. By looking at magzines, it also seems to suggest that the ideal weight ratio between rim and inch should be: (Rim size -10)/weight of rim). For example, (17-10/7)=1. Hence if a 17" rim is 8kg is overweight by 1 kg.

 

What do you guys think?

Hi there,

 

1. My own formula..hehehe.

 

2. When I browsed through the car magazines, most of the reputable brands have 17" rims weighted around 7kg. This led me to derive the formula, there must be some basis for it if the manufacturers are making 17" rims at 7 kg each.

never known of any formula. Take note that all wheels are design to a maximum load index. That is more important not to overload the wheels.

A friend of mine brought his own bathroom scale to measure his stock rims and tyres against the new set rims and tyres, making sure the new one is not heavier. I probably will bring mine to ensure too....hehehe.
