I went with 27-9-14 and 27-11-14. I purchased them through DTD and had a great experience with them for those considering ordering from them.
I had them installed on Saturday and went out riding on Sunday at M&M.
The trails were a bit frozen so I can not provide an accurate analysis of the tires but what I did experience was awesome!
The first thing I noticed was the additional ride height which was to be expected, it sits at least 1.5"s taller now! Where I would typically bottom out a bit, I had plenty of clearance.
Lots of frozen mud that I was able to power through without hesitation when coming through bends hard. All of the water holes were frozen, but we were able to bust through them and when I did sink to bottom and I was plowing the ice ahead of me, this thing really came alive! No hesitation at all getting through mud holes whatsoever! Totally different quad with these tires.
