    Strength:

    Good all around tire. Good tread pattern. Great as a front tire.

    Weakness:

    None if used properly.

    Great tire up front. I've used it carefully out back but at 190# I've had to baby it a bit. Folks complain that it's sidewalls are thin - well, its a full knobbie with a relatively low weight. You can't get something for nothing. For an all-round set up I've found the DryX (XdX) out back and the ACX up front to be super.

    Bonti's TLR rim-tire set up is foolproof on installation and bombproof in function. Their Mustang TLR rim is great. Latterally stiff and holds true very well.

    Like a King rear hub, it's a component (Bonti rim-tire setup) I no longer have to think about.

    Strength:

    grip,grip,and more grip. I tried Racing Ralph's thought they were great in turns. These run with sealent at 20 psi are even better. I let let it fly. Way too much fun.

    Weakness:

    Just put them on, I thought they were way too soft to hold up, but we will see. Make sure the psi is low enough, to much, like all others too bouncy

    Great tire on the dirt at low psi. If you don't stop to put more air in tires for the ride home on the road it feels like you are riding in a sand pit 6 inches deep. I question the durability of the tires, but that remains to be seen. If they hold up well, I will keep them around. Ardents are the next one to try. But so far these grip way too well to take off for now.

    Strength:

    Great tread, good for loose dirt

    Weakness:

    Slashed sidewalls

    5 km to go in a mostly fireroad MTB race (yup, that's called MTB racing in Korea). White spooge started flinging everywhere at 60 KPH. Sidewall sliced like cheese. Never will buy this tire again.

    Strength:

    Light, smooth, Fast rolling

    Weakness:

    thin casing, price $44 each

    Great grip as a rear tire, front tire little loose during cornering. Would not use over sharp rocks they will slice or puncture. But for dirt trails the are great. They also work great with stans tubeless setup.

    Strength:

    Great tread pattern. Has great tracktion in wet and muddy conditions.

    Weakness:

    Side walls. I tore two rear sidewalls. These are not good for rocky conditions

    Depends on the conditions you ride in

    Strength:

    sticks well in the loose dry stuff and hardpack. Good cornering and grabs on hard uphill acceleration. Treadwear is great. Only raced on it one time, first place.

    Weakness:

    thin sidewalls. easily sliced up.

    All around great tire, reliable and predictable.
