Had a thought whilst driving home yesterday, what has more grip for longer? Maxxgrip or Maxxterra? Before replying read the rest! So nice sharp square knobs have a huge part in creating grip but soft compound does as well. Here is where the thinking begins would it be better to get a Maxxterra tire because the knobs will stay sharper longer meaning more grip for longer or is compound so important that even a Maxxgrip compound with worn rounded knobs will still grip better. So essentially what is more important for grip Sharp knobs or compound?

A bald tire will still have grip on smooth surfaces, as long as the compound is soft enough. I say it depends on your surface. If you have loamy, loose dirt, then a sharp edge is more important. Harder, smoother dirt is the domain of soft compounds.

Man, I sure hope that's true because it makes so much sense I'm gonna start parroting it and acting like I either came up with it or it's so obvious any true hard-core rider would know it.

So long as it has some life on the cornering knobs. I feel the softest compound tires tend to lose those almost as fast as the braking knobs. Max terra or black chili or some of the softEr but more durable compounds will bald but still retain some knob life. Which makes them much more useable in the long term than max grip or softest compounds of some other brands. However no matter if they are brand new rubber that isn’t soft enough will always suck.

Logically that makes sense and I think I agree, it seems like on hardpack surfaces and rock faces soft compound would be more important but in soft sandy loose or loam knobs are gonna play a bigger role. Sounds like terrain is the deciding factor.

Def agree that terrain and conditions play a role, but based on my experience I believe that sharper knobs give better grip(unless it's a WTB. Never met a WTB in any tread or compound that liked to stay planted). I run low tire pressure pretty often with longer lasting rubber now(and cush cores). Personal preference in the wet, dry, clay, sand, or gravel. MaxxGrip minions for example, wear too quick for my liking, even the side knobs. When those go, so does my traction and confidence. I think softer rubber (especially at lower pressures) run really, really slow as well. Feels like I have more traction, but my lap times and lack of airtime would show I'm just not pushing as hard or at least not hitting quite the same speeds. Now I only purchase soft rubber when they don't offer the tread I want in a thicker casing or are all sold out for the year.

*Do enjoy a super worn down maxxgrip/supertacky for wide jump trails with huge berms

*Don't usually ride on huge slick, techy, or steep rocks as often found in bc/shore bike vids. Have a feeling that's where a tacky tire might really shine

West coast rider, from bc to cali.
Very curious what others think as well.

I've been testing and I think the best combo for he has been Maxxgrip front and Maxterra rear.
It grips very well and the front and rear wear at about the same rate. I just wish maxxis made the DHR2 DH casing in Maxxterra! It does seem that knobs play a bigger part than compound on the loose trails I ride. Cali can be so sandy Im finding the longer the knobs the better they stop because they act like a paddle. Good to hear others feel the same way!

I thought(and please excuse me if this statement is incorrect)Maxxis 3C tires like a MaxxGrip tire only has the soft grippy compound in the upper portion of the tread not all the way thru and that whats underneath that softer compound is very hard, so my vote goes towards sharp edges no matter what terrain.
