I have been participating in the Dakar, one of the most challenging Cross-Country Rallies in the world with Open Country M/T-R since 2021.
Open Country has impressive performance in off-road terrain with a variety of specs to meet every need. With Open Country, I am confident even when attacking unknown places.
I also sympathize with the way Toyo Tires continues to be a challenger, always aims for better and higher performance for the future.

Toyo Tires not only have the best tires but the best team and support on and off track. Always striving to improve on perfection and with this allowed us to win the Formula Drift Japan Championship with the Proxes R888R Drift.
I use Open Country M/T on my everyday Mazda BT50 that is kitted out for lots of fun plus used to haul the race cars from track to track.

Pikes Peak was an incredible experience for me and my team TCP-Magic, and we were also able to break 2 world records with Fastest Mazda and Fastest Rotary Powered Vehicle in the 101yrs history of Pikes Peak. TOYO TIRES constructed us 2 amazing tire options for the challenging conditions the mountain threw at us with the wild weather. I still can't believe the amount of traction we had and how the tire lasted the massive climb to the top with 156 corners up to 14,000 feet in elevation not to mention fitted on our crazy 2023 Mazda 3 with a 1400h 4 rotor Twin Turbo and RWD conversion running NO traction control, ABS or any type of assists.
