Do lighter wheels really make a difference?

[beakr]

Nearly all four tyres on my Mini Cooper are knackered, and a couple of the wheels are a bit buckled so I thought I would treat myself to a new set of wheels and tyres all round.

I've noticed some wheels are a lot lighter than the standard ones I've got on at the moment, but I would be interested to know how much difference the lighter wheels make - is it worth spending more for less weight? Also bear in mind, I'll be ditching the run flats too

I’ve replaced the factory wheels with a set of very light forged aftermarket wheels made of special strong aviation-grade alloy (by SMW), and I am very pleased with the resulting performance. I saved over 35% as compared with the original cast wheels – and I really feel the difference, especially at cornering. I also noticed that the gas mileage did improve somewhat (though not more than 5% - 8%). So this investment payback will be within a couple of more years, in addition to the enjoyment of better handling.

Good to know. Unfortunately, though I sold the car eight years ago.
