MRT Tires and Whiskey Biz Partner to Launch the All-New Whiskey Runner Tire

MRT Tires is proud to introduce the Whiskey Runner™ Tire, developed in collaboration with off-road personality Bryce “Whiskey Biz” Sparks — a build born from experience, passion, and the shared goal of creating the ultimate all-around tire for the modern off-road enthusiast.

Built for Real Riders, by Real Riders

When Bryce first connected with MRT, it wasn’t about slapping a name on a product. It was about creating a tire that matched his style of riding — and the type of terrain his followers live for.

“MRT was one of the very first sponsors I ever got, and they took a risk on your boy to come out with a brand new mud tire called the Whiskey Runner — and of course, your boy’s logo is on it,” Bryce shared.

Together, Bryce and the MRT engineering team drew from years of trail experience and race-proven design to build something that performs where it matters most — in deep mud, slick ruts, and unpredictable conditions that test both driver and machine.

“We took my favorite tires that I’ve either raced on or trail rode on and combined my favorite features to make an all-around tire,” Bryce said. “Then made sure these things were plenty aggressive for your muddy trails or your nasty, sloppy terrains.”

Engineered with MRT’s Proven Performance

The Whiskey Runner™ features MRT’s signature focus on strength and reliability. Constructed with an 8-ply ultra-tough carcass, it’s built to handle high loads, sharp impacts, and extended trail abuse without compromising ride quality. The aggressive tread design offers consistent grip and self-cleaning performance in mud and loose terrain — while maintaining stability at higher speeds.

As with every MRT tire, the Whiskey Runner is backed by decades of off-road engineering and real-world testing. MRT’s proprietary rubber compounds, reinforced sidewall construction, and advanced tread geometry come together to deliver performance that outlasts and outperforms.

Currently offered in a 35x10R15, additional sizes will be released at a later date. 

A Partnership That Comes Full Circle

For Bryce, this project is more than a collaboration — it’s a full-circle moment.

“Thank you guys, it’s absolutely unreal to see my name on the side of a tire,” he said.

For MRT, it’s another step forward in building tires that connect with the people who actually use them — riders who expect toughness, traction, and trust from their equipment.
