I have just updated to a new set of tyres. My second hand Nitto Trail Grapplers have seen better days so I was doing some research and really torn between another set of Nitto Trail or Ridge Grapplers, Toyo Open Country MT POR or BFGoodrich KM3. Now I pulled the trigger and got a set of BFG KM3 in 295/70R17 yesterday. Oh what a difference it is.
Like driving a completely new car. The ride is so smooth and quiet, the steering is bang on (like driving on rails) and the fuel economy has improved by 1.5 L/100km compared to my old set (given the Nittos a bit heavier). These are just my reflections after one day driving in the city but I will keep you updated. :)
P.S.: I bought these tyres for a really good price from Justin @ http://www.ityres.net.au/
