I recently replaced my origunal spec GoodYear Wranglers on my Ranger. They were okay as road tyres, but not great grip, and 'chirping' every time i did a U-turn, or even when I turned a corner! I put a pair of Maxxis on the front a few months ago, because one of the original GoodYears developed a bulge on the side wall (after 12,000Ks). These were cheap, and had even less grip than the GoodYears!.
In work mode back in Australia, I always ran either Coopers or BFG. I eventually stopped Coopers because I was getting too many punctures.
I bit the bullet here, and put a set of BFG AT ko3 265/65/18 s on. It was the best move I have made for a long time! They are quiet , have good grip - on and off road - and they look great on the car too. Those raised white letters are good for at least another 25 horsepower - lol. Not cheap, at 34k for 4 - but totally worth it for safety and peace of mind.
if you want some slightly used Maxxis - they are slowly rotting behind my shed!
