From suspension setup to power delivery, tires play a critical role in the performance of Monster Energy Supercross bikes. Learn more as Dunlop explains all of the variables that go into pre-race tire selection.
I live in Michigan where the trails are largely loam with occasional stretches of pure deep sugar sand, as well as hard packed dirt (and the loam or dirt may have some rocks in it, and of course the dirt can get muddy, and the trails often have roots and in the fall leaves, sometimes wet leaves, all over the trail).
My bike came from factory with Pirelli MT 320s which are, as near as I can tell, an all terrain intermediate tire that I've been pretty happy with except for one thing - when, on a loamy or dirt trail, I have to transition to pure, deep sand.
Now the Pirellis are supposed to be inflated to about 16 psi but as near as I can tell most riders in Michigan, including me, ride with the rear tires at about 12 psi and the fronts around 8 psi. We reduce the air pressure as then the softer, flattened tires gives more traction in the sandy sections of Michigan trails. Now in reality, I may even deflate my front down to as little 6 or 4 psi, and rear to 10 or 8. Why? Because traction in Michigan sand is variable depending on climate. If it is wet and cool, even deep sand gives reasonable traction. If it is hot and dry the sand is highly unstable providing minimum stability. Of course, the problem with letting out so much air is that most of the time I (we) in Michigan are on loam or hard dirt, with roots and rocks interspersed, so it's unwise to ride with too little air in the tires.
Now, no matter how experienced one is with sand, if is possible after riding a long stretch in dirt or loam to make a possibly serious mistake when one encounters the sand. Almost invariably my most serious mistakes happen in sand. It's usually a function of the front tire digging in to hot, dry sand or washing out. I want to emphasize how dangerous this is. If you don't often encounter hot, dry sand in your riding then you may not be able to appreciate the challenge that sand can be, especially when riding in proximity to trees (we have lots of trees and sand in Michigan).
I was watching the Lucas Oil Pro Motocross race held at Southwick (on my computer) in 2017 and I was surprised to see how many (not all) of the top riders were uncomfortable with the sand at Southwick, and there were a lot of crashes. Aaron Plessinger took a bad spill on a fairly flat straightaway when his front tire washed out and then dug into the sand. It was then that it dawned on me that if the pros struggle with sand, then I need to be proactive and perhaps more aggressively seek solutions.
I'm starting with tires, but my research raises more questions than provides answers so far -
1.) Pure sand tires, aka. "paddle tires" are too extreme for typical Michigan trails, which are mostly loam.
2.) So called "sand and mud" tires like the Dunlop Geomax MX12 are purported to be of a firmer rubber compound than a standard off road or MX tire, because the manufacturer wants a "firm" tire to to "dig in" and get traction in sand and mud. Conversely, they use a soft rubber compound in bikes that frequent hard surfaces like rock. The soft rubber is supposed to grip the hard surface better. However, here I (we) in Michigan are DEFLATING tires to get them flatter and softer, so why would I want buy a tire with an even stiffer rubber compound (here in Michigan, when riding in sand, if you can't depress the knobbies on your front tire with your fingers you have too much air in the tire - they have to squish, or you're risking the tire will dig in, or wash out, and throw you off bike).
3.) Sand and Mud tires don't have the regular knobby configuration, as they are designed to push sand mud and the self-clean, but then the problem becomes, if one puts "sand and mud" tires on a dirt bike and 80% of the trail is loam or hard packed dirt, is the cure worse than the disease? What's it like riding a sand and mud tire on loam or firm dirt?
In short, while I could stick with a general purpose tire, and continue to deflate, it's those hair raising episodes in sand that compel me to seek a better solution. Any words to the wise out there?

I'm looking for a front tire for my 200XC, I ride mostly sand, soft loamy dirt, and a little bit of that tacky red carolina clay. Like most 15 year olds I don't have a whole lot of extra money lying around as my only income is during summer and fall when I'm cutting grass and raking leaves so I can't be spending 80 dollars on a tire. My bike still has the original front tire and it's been patched so many times I believe there is more patch than actual tire, the thing is awfully dry and missing a lot of sideknobs and is probably too sketchy to continue riding on. What front tire will last a fair amount of time, perform well on the mentioned terrain, and not kill my wallet? thanks.
