I've gone through a few sets of BFG AT KO1,2,3 and also a summer on the older Duratrac. These Nokians are quieter and you can see the tread pattern. They are claimed to be better in rain and slush but also I watched a test on snow for AT tires which has them on top.

Checked out the Goodyear Wrangler Duratrac, and they are rated excellent in every category as per TireRack.com, however they only come in a SL load rating, meaning 35 psi max and a 113T speed rating, which is 118 mph. My ‘22 Defender 110 came fitted with Pirelli Scorpion All Season, 255/60R20, having a XL load rating, 50 psi max and a speed rating of 113V, 149 mpg. Now, I have no need nor intention of driving anywhere near that speed, but I have reached approx 112 -115 mph for a very short stint. Not sure how a rating of 118 mph relates to approaching any speed near that, but I would feel safer with a higher speed rating. And the XL load rating means there is ‘extra internal reinforcement’ according to tire data sheets. Apparently though, there are many vehicles in our category that ride on SL load rated tires every day with no problem. Tires in my original size, 255/60R20, are limited in choice, so I’m going with 275/55R20 which offer many more options to choose from. So at this point, my specs have my short list narrowed down to Continental Terrain Contact H/T (XL load rated, 117H speed rated, 130 mph); Nitto Terra Grappler G3 (XL load rated, 117T); and Cooper Discoverer Road+Trail AT (XL, 117H). The Coopers I have not seen mentioned here previously, but they have great reviews and are rated excellent in every category also at TireRack.com I’m interested if anyone has any of these on their Defender and appreciate any feedback. Thanks.
Edit: Just occurred to me, since I’m pulling all four wheels off, swapping tires, balancing, etc., would it be wise to replace the TPMS monitors at this time? The vehicle just turned 4 years old last month. Also, considering purchasing 5 tires and changing out the spare to match. Would hate to have to put on an unmatched type and tread. Or not replace it and regrettably find out two years from now if I need to replace the spare that they stopped producing that model of tire.
