I have changed tires to Dunlop sp sports Lm703, costed 8k for 4 tires after exchange, they are 175/70/r13, result is awesome, even less road noise, better grip and no effect on steering or any heavy feel. I also ordered its seat cover custom built in Leatherite, it will cost me 6k, I will share the pics on tuesday inshaAllah. Quick feedback from my side on WagonR is its awesome, its practical and i m enjoying it. i still to run its ac on position 2, even in afternoon, it is handling karachi temp pretty well (for me) at position 1 of ac knob.
