Weight of alloy equal to weight of stock steel rim

Hi all,

There was an observation which I would like to share. I weighed the alloy rim as well as the stock rim today morning & they turn out to be of the same weight. Now this was no digital weighing machine, but there was hardly any difference (assuming the small difference due to analog machine errors). I had however expected the alloy rim to weigh lesser.

From this, I have decided never to upsize the rims unless the rims are of a really upmarket company (read as 'performance'). Otherwise, with such alloys (Neo, Plati, etc) & that too an upsize, we are actually increasing the unsprung weight, which should ideally reduce for the car to perform better (this comes from what I read on other TBHP threads).

NOTE: By the observation stated above, I do not intend to say that Neo or Plati or any other brands are bad. They can probably just be called affordable hatch-backs in the world of alloys.

Also, after the balancing was done, there was a little metal sound coming from the front tyre (left or opposite to driver's side). Upon checking, it was learnt that the weights put on the inner side (looked like silver tablets) were touching the brake caliper & causing the sound. Also upon braking, the sound vanished, maybe because the caliper is pulled towards the centre of the wheel to grab the brake disc. Please comment if anybody has faced a similar issue with their rims.

Thanks.

You'll find a weight difference only if you compare with Magnesium alloys. Also called Mag wheels.

From above, I understand that such magnesium alloys are the upmarket or performance alloys which come at a much higher price. Please correct me if I understood wrongly. Also please mention a few brands in case you might be aware, which manufacture such alloys. I want this information just to add to my knowledge.

Thanks.

Sorry not sure about the brand names. I guess OZ, BBS, etc. Know the names from NFS series. The wiki is Alloy wheel - Wikipedia, the free encyclopedia

Mags are not available widely in India. What you get is Aluminium Alloy wheels. They are lighter than the steel wheels, but not as much as mag wheels.

I had a friend in PUC who had Mag wheels and racing slicks on his RD350. Not sure where he sourced them from though.

Thank you guys for your prompt responses. And as Nikhil mentioned, I am sure that the Mag wheels are not widely available in India, & from what I could infer, it is primarily to do with the higher cost.

As for weight, I feel there must be different grades (or classes) in Aluminium alloy rims, as the Neo rims I got are no different than the stock Alto rims in weight.

Regards.

Nick and Asdon, why did you not go for 165/60/13? Any particular problems? As I understand, rims should be 13 x 5J.

I would have gone for it, but came to know that there is a speedometer error going to happen, and it will not show the exact speed at which you are driving, and it will be a % and can not rectify that, that was my concern.

currently i am running 12" alloy wheels bro, i had to change those also, if i want 13" tires, and one more reason, i wasnt willing to change my 12" alloys, by the way, my next upgrade would be a 14" tires and alloys.
