The 3D bit of the name relates to little pyramids in the smaller sipes that are meant to lock the blocks of rubber together. I think it's just a marketing differentiator.
The XM bit means Xtra Mileage and only time will tell.
I came home in the pi$$ing rain and I gotta say that although brand new they felt as good as the Storm Ultra 2's that they've replaced.
I didn't really need the rear but I fancied a matched pair so have a part worn at home "just in case".
Fingers crossed these new tyres live up to the hype
Oh yeah and ?30 (i.e. free fitting) until the end of the month @tu* meaning I paid ?220 ride in/ride out.
