Change your stock tyres to 205/70 R15 Continental 4x4 Tyre for better off-road grip than the stock tyre's and the stock tyre's lasted for me for about 10,000 - 15000 KMS of immediate rough road tracks frequently. So now i have changed to 205/70 R15 Continental 4x4 and this gives a better grip and it had improved the steering hardness by a lot than the stock tyres, may be it has more treads than the stock tyre's.
If you need an A/C and better comfy seat replacement for your gyspy then go to coimbatore Koyas for doing the modifications as per your choice. And remove the side passenger side step or footrest if you are going to do a serious off-roading.
Happy Miles ahead.
