I know those big tyres/alloys look great but why do we forget that when the manufacturers are providing good/decent tyres as OE ,they aint fools ,they know what the car actually requires and what would serve the purpose .

P.s The above is based on what i 've actually felt and experienced many times but i may be wrong as i dont think i have much f knowledge about these stuffs ,so all those gurus who disagree please do enlighten the facts .

Thanx.
Don't worry about your knowledge, Beemer. It is spot-on, I assure you!

Manufacturers do not make the typical Indian family saloon for the race track.
They are made for normal city roads, with the occasional loose road metal of heterogenous sizes.

In the rare event that you happen to only drive on mirror-flat roads (such as race-tracks and expressways), you can afford:

1. Very low ground clearance.
The lowering of center-of-gravity will benefit stability tremendously.

2. Very low profile, very wide tires.
Now you've restricted yourself to huge wheels to maintain a sensible overall outer diameter(OD).

This will let you take corners at much higher speeds. And since the race-track is free of pebbles, it won't rattle your teeth and bones and other things.

Ferraris, Maseratis and Aston Martins are made for the race track and race-track-quality roads. So they have low ground clearance, low profile Z-rated directional radials and huge alloys.

We see pictures of these cars, get "alloy-happy" and mindlessly equip our four-door economy saloons with "upsized" big alloys and low-profile wide tires. Just to match the looks. And then we suffer rattly rides wondering why?
