Tyre issue

[ipbr21054]

Grand Vitara 54 plate.
Both front tyres are going bald on.
N/S front tyre bald N/S edge.
O/S front tyre bald N/S edge.
I have noticed a slight drift to the N/S if you let the wheel go.
Also if i turn nearly full lock then drive right it feels as if the anus is going to topple over,if you know what i mean, like an egg ?
Once in a straight line seems ok.

Any advice where i should look or anybody had this before.
