Hey Storm,
well buddy, was on the road today looking for the above mentioned tyre sizes for your Defender and here are the details:
went to just 2 shops today and both these shops had these tyres with them.
Tajamal Traders
Near Gourmet Bakers and Gourmet Restaurant
Faisal Town, Lahore.
285/70R16 Yokohama V801 (around 12 tyres of the same size)
Price: around 9.5k's
Jaji Traders
Opposite KIPS College
Faisal Town, Lahore.
285/70R16 Yokohama (around 8 tyres of the same size)
Price: around 9.5k's
P.s. asked for just the 285/70R16's because i thought they were your first choice tyres.
Note: Prices were asked just for the sake of asking, no bargaining in it
