    After contemplating for a long time, finally decided to take the plunge. Went ahead with 16" after my stock tires worn out.
    Specs: 16", 100 pcd, 8.5J wide GTR rims. Got hub rings made from a lathe and bought 12x1.25 wheel bolts too.
    Tire: Nankang NS20 205/55-16.

    After lot of discussion and confusion bought Konig Britelite 15" alloys for my Palio S10.

    15" Alloys with 195 55 R15 Continental MC5 tyres. Superb grip and less noise.

    It is 100 PCD and got the hub rings from @Italia-Linea 's workshop.

    Recently changed my alloys to Momo Revenge 15inches with 4holes/98 PCD, during my last highway drive felt steering vibration in 120 kmph and went away when i reduced the speed, but this is not consistent sometimes even in 130+ i never found the vibration, understand adding hub ring will solve the problem, but is it mandatory, because its same spec as fiat.

    With aftermarket alloys, HUB centric rings are extremely mandatory. You got the right PCD, but the Momo's center is not fitting flush on the HUB of car, hence vibs coming up.
    Further, the Hydraulic steering on Fiats feeds back very well and so you feel vibs fully.

    MOMO has their own hub rings which are perfect fit and are of pretty good quality. a friend bought momo for his skoda and got hub rings along with it, no vibration issue or whatsoever. See if you can obtain the same.

    @sunswape @varunrtr thanks for the reply, let me check with the dealer for the same.

    Please find the spec for stock vs aftermarket, the pcd and the hub dia seems to be same, then what makes the difference here

    just want to understand technically

    Stock alloy (took from earlier post in teamfiat)

    Rim size (R): 15
    Rim Width (J): 5.5
    Offset (ET): 41mm
    Pitch Circle Diameter (PCD): 98mm
    Hub Diameter: 58.1mm
    Holes : 4holes

    After market

    Rim size (R): 15
    Rim Width (J): 6.5
    Offset (ET): 38mm
    Pitch Circle Diameter (PCD): 98mm
    Hub Diameter: 58.1mm
    Holes : 4holes

    The outer hub dia of the wheel hub and the inner hub dia of the alloy wheel may be slightly different which is causing the vibes. The hub rings plug that gap. Just get a vernier caliper n measure it for yourself.

    Could be a late reply from my side,
    but all aftermarket alloys are made with a slightly larger center mounting hole than standard. So that it can be used among various cars. This is also the reason which create problem in some cars.
    This usually occurs, as the hub should take the weight of car, the bolts are just to hold the wheel at place. Now because of lack of flush fitting of aftermarket alloy's center hole onto the hub, whole weight of car gets onto the bolts and hence at high speeds these bolts start flexing.
    Hub should be flush fit and in order to make them so, metal rings are inserted which fills the gap between car's hub center and aftermarket alloy center mounting point, thereby distributing the weight evenly onto the hub, as it should be.


    Cheers.
