DUNLOP MX14 SAND TIRE: PRODUCT REVIEW

PRODUCT: The MX14 is Dunlop’s current offering for sand and soft terrain. It’s the latest in a long line of “scoop” tires that included the MX11 and MX12. The tire has made an especially big splash this year because Eli Tomac and a number of other top pros have been using it in the 2022 Lucas Oil Pro Motocross series, even on some hard-packed tracks. The people at Dunlop say it’s the tire that generates the smallest sales numbers and the most attention. Sand tires traditionally are viewed as very specialized, particularly because soft tracks often become harder and harder as they mature. Pure sand tires aren’t used as often as intermediate tires, even in the desert where rocks are common and can damage the tall lugs of a specialized sand tire.

The goal for the MX14 was to make a soft-terrain tire that isn’t limited to pure sand. The distinctive scoop arrangement of the knobs was kept but with lugs that were reshaped for durability. Dunlop reworked the casing and increased the knob height by 18 percent. The contact patch was also increased.

Eli Tomac has been one of the most vocal supporters of the Dunlop MX14. He used it in both motos at Spring Creek in Minnesota, which has intermediate terrain.

 

OUR TAKE: In deep sand the MX14 behaves almost exactly like the MX12. If you’ve never ridden with a scoop, you’ll be amazed. A dedicated soft-terrain tire is an unfair advantage in sand, and the MX14, like its predecessor, is among the best. Straight-line acceleration is excellent. That translates to much better starts. If you are a 250 four-stroke rider, in fact, you have to relearn your start-line habits. The MX14 gets so much more bite that it drags the motor down. You have to concentrate to keep the revs up. Even on a 450 there’s a noticeable drop in revs. A 120/80-19 MX14 weighs 12 pounds, which is slightly lighter than a Dunlop intermediate tire of the same size.

The big difference for the 14 compared to other sand tires is how it behaves on mixed terrain. We initially tested the tire at Glen Helen Raceway, which is one of those tracks that was once considered loose and sandy, but has since become packed down and become harder over the years. Some sand remains, but there are sections that are hard clay, too. The MX14 worked amazingly well there. Even on blue-groove hardpack, traction was predictable. When it broke loose, it was gradual not sudden. It won’t outperform a tire that was designed for that application, but it’s better than any of its predecessors. In the past, we would never choose a sand tire for a track that was half sand/half hard. The MX14 makes us rethink that. We can hardly wait to use it at a Havasu GP, which has notoriously mixed surfaces.

The MX14 is the successor to the MX12. Dunlop jumped over the MX13 designation.

 

Wear, of course, is an issue once you get the MX14 out of its element. We rounded one off dramatically in a few hours of riding on intermediate terrain. Not surprising. In sand, it takes a very long time to generate the same wear. We never saw knobs chunk or tear. As with most tires, pricing varies wildly. The MSRP of a 120/80-19 is $140, but we routinely see prices in the $105 range online.
