Just got back from Maine for the weekend and ran tires this time, 25" rawhide III's. Swimming this time got me 2 mph on the GPS, last time up there with the 14.5 pro series track I couldn't even get a reading. This is on the 6x6 Bigfoot, from what I've seen in videos the 8x8's with the same tracks swim quite well. Just thought I would give an update.
