Dee­gan 38 All-Ter­rain Tires

Back in 2015, Mickey Thompson (MT) in­tro­duced the Dee­gan 38 - I be­lieve the first sig­na­ture tire of­fered by a man­u­fac­turer. In this case, branded by Brian Dee­gan, found­ing mem­ber of Metal Mul­isha and famed X-Games mo­tocross rider who made the tran­si­tion to off-road rac­ing,… and Rally cross and Mon­ster trucks. Put the guy on dirt with wheels and he ex­cels.

The orig­i­nal Dee­gan 38 is a mud ter­rain

tire. You can be for­given for think­ing the 38 is the tire size, it’s not - it is Dee­gan’s rac­ing num­ber. Two years after the suc­cess­ful in­tro of the mud tire, Mickey Thompson just re­leased the Dee­gan 38 All-Ter­rain, and nat­u­rally I had to have a set. The cur­rent size range is 29" - 33" OD for wheel sizes of 15"22", in stan­dard and LT ratings. We grabbed a set of five LT285/70R17, wrapped them around a set of Mickey Thompson 17x9 Dee­gan Pro 2 wheels, and started climb­ing.

The road man­ners in­spired in­creas­ing lev­els of con­fi­dence as we cranked harder and harder cor­ners, push­ing the lim­its of our en­hanced Ter­aflex sus­pen­sion. If you need to avoid the A-hole turn­ing left from the right hand lane in front of you (re­ally, you couldn’t see a two me­tre tall bright blue Jeep in your driver's mir­ror?), you’ll find the corner­ing and brak­ing ex­cel­lent.

Wet roads are the norm rather than the ex­cep­tion in spring­time, and the spe­cial sip­ing and sil­ica re­in­forced com­pound did their job of hold­ing onto the pave­ment in hard brak­ing and corner­ing.

With the new Ram­page Trailview soft top mounted, I ex­pected to hear a lot more noise from the large voids and non-di­rec­tional tire pat­tern. Yes, they were slightly nois­ier than the Bl­iz­zak win­ters that just came off, but much qui­eter than the 35" MT ATZ P3 from fall. If your rig is also your daily driver, and your sig­nif­i­cant other is not a wheeler, this is cru­cial.

At test time, it was the end of April in Bri­tish Columbia. At this time of year, heavy mists cling to the moun­tain­sides most morn­ings, the snow lines and lev­els change without pat­tern or warn­ing, and the win­ter run-off starts to fill the rivers, streams and this year, the cities. A state of emer­gency was called and hun­dreds were evac­u­ated from their homes as melt and rain wa­ter over­whelmed river­banks, flood­ing houses and apart­ment build­ings.

We aired the tires down to 10 psi, which pro­vided a nice bulge in the side­walls and a good foot­print against the earth. As we climbed, the tires held ef­fort­lessly in the loose dirt and rocks. Fur­ther up, gath­er­ing rain and melt wa­ter cre­ated axle high mud and bumper high wa­ter pools, fi­nally chang­ing to sticky wet snow. Nat­u­rally you don’t know how far a tire can take you un­til you get stuck, so I did - when the snow reached the frame. I needed a quick tug to break free and get over the crest (thank-you Rugged Ridge soft shack­les, and Marc in your Ru­bi­con).

The tread pat­tern shed the small rocks, mud and snow cleanly, al­ways pro­vid­ing empty tread ready to ea­gerly claw up the trail. And what MT dubs Sideb­iter II tech­nol­ogy - the pat­tern of al­ter­nat­ing shoul­der tread blocks - work like trac­tor treads to move you through any­thing they can hook their talons into.

Sharp rocks and fallen trees are al­ways cause for con­cern but the sil­ica-re­in­forced rub­ber com­pound proved tougher than the trail, prov­ing MT’s claim that the tires are chip and cut re­sis­tant.

MT backs up the tire with an in­dus­try lead­ing 60,000-mile (P-met­ric) and 55,000-mile (light truck Met­ric sizes) Lim­ited Tread Wear War­ranty.

As tire tech­nol­ogy con­tin­ues to im­prove, off-road­ers ben­e­fit more than other driv­ers. If you even think it’s time for a new set of All-Ter­rain tires for your 4WD, buy these.

Large open tread blocks shed mud, snow and dirt while sip­ing grabs wet pave­ment for im­proved corner­ing and brak­ing.

Al­ter­nat­ing shoul­der tread blocks have a scal­loped edge for ex­tra trac­tion in mud and snow.

Treads clear the wet sticky snow eas­ily to claw down the trail.

Up the steep slope in loose dirt like it’s a ca­sual stroll in the park.

Slow and steady with no tire spin through the gooey muck
