i am having good fun with Specialized Ground Controls front and rear, they are good in the mud and pretty useful on wet roots, plus weigh around 650g which is okay for a sturdy all rounder, i plan to run these all winter even though I have beavers, easy ti set up tubeless like all spesh tyres,
beavers I found were good in a straight line and deep mud, but wash out easily on roots and muddy corners, in fact i had to adapt my riding and lines to except the rear was going to wash out on any root, but they are light, sadly the walls are a bit thin, i have made one repair already,
purgatory’s I got rid off after a couple of rides, the large centre knobbles give them no bite on the front in mud, the centre knobs were also a harder compound so also rarely gripped roots, plus they weigh around 850g, too heavy,
