Funny to hear u say that... cause i have actually been thoroughly impressed with them ... only down fall is 6 ply ... but i have 1300 miles on mine and they are still over 80% tread easy ... we had the snowiest winter in Missouri we had in years with one being 17 inches around our county and couldn't believe how well they did and u know the sloppy mud was bound to come once the snow melted and the big horns just couldn't be stopped ... but when ready to replace I'm goin to look into the ITP blackwater evolutions in 28s because there similar to the bighorns in that there a non directional and more versatile for the rocks ,mud ,snow and road riding we do but there 8 plys to give me a little better peace of mind when in the creeks around here to not slice a tire open .... big plus with the itp's is u can get them in our defender factory widths 28" tall to use on our stock wheels ... but I may buy 28x10x14s all they way around with new 14x7 wheels ( have to run 1.5" or 2" spacer in rear to allow tires to track the same ) the benefits of that route is the ability to rotate ur tires for longer tire life .........
And in my opinion as long as ur not wanting clearance for some serious mud riding ... tightening ur shocks up for that taller stance and 1" bigger than stock tires is the way to go ... keep low center of gravity for ur trails and cornering plus ur defenders axles , joints and drivetrain will thank u and keep running flawlessly for miles and miles
