Looks are de­ceiv­ing when it comes to the Maxxis RAZR MT

MAXXIS SAYS THAT THE RAZR MT IS THE com­pany’s flag­ship mud-ter­rain and that the tire was engi­neered with know-how gained from in­volve­ment in off-road rac­ing. We say don’t let the ex­tremely ag­gres­sive and open-lug tread pat­tern of the Maxxis RAZR MT fool you. Of course, it’s ob­vi­ously a mud-ter­rain tire, and most of us would as­sume that the large voids and chunky lugs would make for an ex­tremely loud on-road ex­pe­ri­ence. This could not be fur­ther from the truth. In­ter­est­ingly, the Maxxis RAZR does cre­ate audi­ble noise up to about 55 mph. Af­ter that, the tire starts to quiet down, and by the time you reach 70 mph, the Maxxis RAZR tread emits about the same noise as a much less ag­gres­sive all-ter­rain tire or mildly treaded mud-ter­rain.

We mounted our 32x11.50r15 Maxxis RAZR tires on 15x8 alu­minum wheels and slung them onto a 4,000-pound 4x4. We skipped on the tire balanc­ing to see how smooth they would roll, and we were not dis­ap­pointed. They roll very smoothly, even un­bal­anced.

Our ve­hi­cle orig­i­nally came with 31x10.50r15 tires. The door tag spec­i­fies 26 psi in the front and 29 psi in the rear. We found that the 32-inch Maxxis tires made best con­tact with the road at about 25 psi on our 4x4. Af­ter about 3,000 miles, the RAZR tires were due for their first ro­ta­tion. Based on the tread­wear we’ve seen so far, it should be easy for us to get 25,000-30,000 miles from the Maxxis RAZR, which is ac­tu­ally good for a per­for­mance mudter­rain tire on an IFS 4x4.

When we hit the dirt, we aired the tires down to 12-15 psi in most cases. The ag­gres­sive tread keeps the ve­hi­cle mov­ing forward with con­fi­dence. In the sand we could have gone down as low as 10 psi. At this pressure we would have to avoid the urge to throw the truck side­ways. Too much lat­eral sand sling­ing could pitch a tire bead at 10 psi or lower, which is some­thing bead­lock wheels could keep under con­trol.

If you fre­quent lots of dif­fer­ent types of ter­rain and weather con­di­tions through­out the year, you’ll ap­pre­ci­ate many of the tread char­ac­ter­is­tics found on the Maxxis RAZR. Maxxis says the tire fea­tures a new off-road com­pound with new chem­i­cal fillers for max­i­mum tear and chip re­sis­tance and in­creased tread life. De­spite our many at­tempts to chunk the tread by spin­ning the tires on dirt roads lit­tered with sharp gravel, the tread lugs re­tained their shapes, so the new com­pound seems to be work­ing. Other ad­mirable tread fea­tures in­clude siped tread blocks for bet­ter wet weather and win­ter trac­tion and stone and mud ejec­tors to im­prove self-clean­ing per­for­mance and min­i­mize rock re­ten­tion. The Maxxis RAZR re­ally shined dur­ing a quick rip in thick, tacky, and slick mud that would have clogged up lesser treads. We were eas­ily able to spin the tires clean for a fresh bite, even with a low-horse­power V-6 en­gine.

Over­all, the Maxxis RAZR would make a great trail rig tire given the ag­gres­sive tread, avail­able sizes up to 40 inches in di­am­e­ter, and durable three-ply side­wall. How­ever, the ad­mirable road char­ac­ter­is­tics and large di­am­e­ter flota­tion sizes with E load rat­ings would make the RAZR a great lifted com­muter or tow rig tire too. With the RAZR, you’ll cer­tainly never have to worry about getting stuck when pulling a heavy trailer or camper into your fa­vorite of­froad camp­site.

<- The sipes within the tread lugs of the Maxxis RAZR of­fer bet­ter trac­tion on- and off-road in wet and icy con­di­tions. The unique stepped shape of the lugs provides more bit­ing edges for im­proved trac­tion on loose soil and jagged rocks. <| The Maxxis...
