He're the fool proof guide to picking the right tires for trail riders in the Pacific Northwest. From Ashland, through Portland, Seattle and the North Shore of Vancouver, up through Whistler and Pemberton, the answers are clear as a face full of November loam.  If you're clad in spandex, rockin' team kit, and only care about how fast you climb, then move along, this isn't for you. This is for riders doing big climbs for rowdy descents.  Endu Mountain biking! 

Most of us aggressive riders run "normal" width tires. The wider plus tires tend to explode when pushed hard, and are better for mellow riders, or as your third bike.  Keep it between 2.3" and 2.6", and you'll be all good.

What are the best mountain bike front tires?

The Maxxis Minion DHF is still, after all these years, the best all-rounder, especially if you gravitate (see what I did there?) toward flow trails, jumps, hardpack, or summer conditions. The newer Maxxis Assagai is becoming quite popular for softer conditions, but it has limitations. The DHF and Assegai are both amazing tires, so just pick one and go for it. 

Minion DHF, Magic Mary, TRS Race

Maxxis Minion DHF

Still the best all-rounder on the market. Shines on hardpack corners (berms), loose junk over hardpack, soft soils, and wet roots. Doesn't brake as well as some others, and not great in the kind of mud that packs up your tires.

Width:  Get the 2.5 WT. Maxxis claims they are for 30-35mm inner width rims, though I have friends who like them on the older Stan's Flow EX at 25.5mm.

Rubber Compound:  This is critical! I recommend the 3C MaxxTerra compound for most riders.  You can run this as either a front or rear tire, and many of us start with it in the front, and then rotate it to the rear when it's partially worn, putting a freshy on the front. It's a great tire in the dry, in the wet, riding pretty much anything, anywhere. 

Stepping it up a notch, I usually run the softer 3C MaxxGrip rubber. You'll get better wet grip on slimy roots, it won't last as long, and you'll find it very slow rolling if rotated to the rear.  This is splitting hairs for most riders, so if you're not sure, get the MaxxTerra, especially if you don't ride deadly winter tech with slimy roots.

Sidewall:  Run the EXO. It's a fairly light, single-ply sidewall. If you're blasting hard enough to need the heavier DoubleDown sidewall or an insert like CushCore, you probably already know everything about tires and aren't reading this anyway. EXO weights: 27.5" - 945 g, 29" - 1005 g. MSRP $75.

Maxxis Assegai

A newer kid on the block, getting a lot of hype, but more condition-specific than the DHF. Fantastic in loose dirt, and great in most conditions, but not as solid on hardpack as the DHF. If you don't care about efficiency on climbs, the heavier Double Down with MaxxGrip rubber is amazing, but that's too much weight for most trail riders.

Width:  Get the 2.5 WT, and all width comments about the DHF apply here. If you have 30-35mm (inner width) rims, the 2.6 is also a good choice.

Rubber Compound:  Options are still limited, so get the MaxxTerra compound. It's good on wet roots, but Maxxis needs to offer it in EXO/MaxxGrip before I can fully get behind the Assegai as my favorite winter trail riding tire for the front.

Sidewall:  Run the EXO. It's a moderate weight single-ply sidewall. You can step up to EXO+ for a little more support at the cost of 90 grams if you're a bigger shredder. EXO weights: 27.5" - 1000 g, 29" - 1120 g. MSRP $75.

Other Contenders

Schwalbe Magic Mary:  This used to be one of my top choices, but the flimsy SnakeSkin sidewalls aren't up to the level of the competition. They require more air for support, sacrificing suppleness and traction on roots. For a heavier enduro-weight tire, the Magic Mary Super Gravity in Ultra-Soft rubber is one of the best tires out there. It's great in soft conditions, much like the Assegai. 2.35 Super Gravity weights: 27.5: - 1100 g, 29" - 1165 g. MSRP $98. Here's your heavier enduro front tire: Schwalbe Magic Mary 2.35 Super Gravity Ultra Soft

e.thirteen All Terrain Trail in MoPo rubber: MoPo is an amazingly grippy rubber with sidewalls that feel amazing, while not being overly heavy. They have two limitations: the lugs aren't very tall, so not a top performer in deep, sloppy dirt. It's also a fairly square tire, so only run them on rims 30mm (inner width) or less. That said, this could be the best tire available for slick rock faces and my top choice in places like Squamish, Whistler and the North Shore of Vancouver. 2.4" Trail MoPo wights: 27.5" - 960 g, 29" 1015 g. MSRP $72. Here's your front tire: e.thirteen All Terrain TRSr 2.4" MoPo

In sticky mud the Assegai and Magic Mary outperform the Minion DHF.

What are the best mountain bike rear tires?

In the world of rear tires you need to consider rolling resistance as well as all-out grip. 

A lot of riders will run a partially worn DHF MaxxTerra in the rear.  It doesn't brake as well as a DHRii or roll as fast an as Aggressor, but it's a good rear tire, and I've got no complaints when I run them, winter or summer.

Don't be tempted by an ultra fast rolling, long-lasting (hard rubber) rear tire for wet weather riding. It'll suck, and you'll hate winter riding. Get the sticky rubber or don't bother venturing out. 

Minion DHRii, Aggressor

Maxxis Minion DHRii

The DHRii is an amazing tire for wet weather riding. It rolls admirably fast, brakes and corners well, and has great traction on wet roots and rocks. There's some BS out on the web that the DHF rolls faster, but these pundits haven't actually tried them back-to-back.  The DHRii has shorter center knobs and rolls faster than a DHF. 

Width:  Get the 2.4 WT.  On narrower rims, 28mm or less, the 2.35 is a good option, but the side knobs aren't as robust.

Rubber Compound:  You want the MaxxTerra.  It's got great grip in the wet, and lasts reasonably long. If you're tempted by the faster rolling Dual compound for dry riding, you should probably get an Aggressor.

Sidewall:  As as with the DHF, get the EXO unless you know what you're doing and need the heavier Double Down casing. EXO weights: 27.5" - 900 g, 29" - 955 g. MSRP $75.

Here's your rear tire: Maxxis Minion DHRii 2.4WT EXO 3C MaxxTerra

Maxxis Aggressor

The Agressor has tighter knob spacing and a harder rubber than the DHRii.  It rolls faster, lasts longer, and is a great tire in the drier months. In the summer I find it gives up little to the DHRii.  In the winter, it's not near as grippy. I'll happily run the DHRii year round, but not the Aggressor.

Width:  Get the 2.5 WT.  If you're on a rim less than 28mm inner width, then the 2.35 is the better option.

Rubber Compound:  It only comes in the hard Dual Compound, which is why it's a dry season tire. This is a long-lasting tire.

Sidewall: As as with the other Maxxis tires, get the EXO, unless you know you need the Double Down. EXO weights: 27.5" - 915 g, 29" - 980 g. MSRP $65.

Tire Pressures

You want enough pressure that you don't immediately flat spot (aluminum) or crack (carbon) your rear rim, but as low as you can go without the tires getting squirmy. 

For front, start in the 21 - 25 psi range, depending on rider weight and terrain. I have to push the upper end of this on my old backup rims that are only 23mm (inner width), and run higher pressures in the summer than I do in winter. Schwalbe Snakeskin casings are fairly light, so I run 2 psi more in them than other tires for better support.

In the rear start in the 25 - 30 psi range.  I run 25 - 28 psi, but on certain gnarly, rocky trails there's no way I'm in the low end of that or I'll crack (another) carbon rim.

A warning: pressure gauges are notoriously inaccurate, so these numbers are just a starting point. Find your ideal pressure through trial and error, and always use the same gauge.

There are a lot of variables here. Rocky terrain? Go higher pressure. Heavier rider? Go higher pressure. Narrower rims? Go higher pressure. Wet roots?  Go lower pressure. Smashing berms? Go higher pressure. Wider tires? Go lower pressure. Sessioning bigger jumps like at Duthie Hill? Go higher pressure (30 psi f/r). Sandy trails? Go lower pressure.
