FAQs:

- Is the Toyo R/T louder than the Open Country A/T III?

The R/T is slightly louder than the A/T III due to its larger tread voids, but it is significantly quieter than a traditional mud-terrain (M/T) tire. It uses computer-optimized block patterns to minimize "highway hum.

- Does the Toyo Open Country R/T have a mileage warranty?

Yes, unlike many aggressive off-road tires, the Open Country R/T comes with a 45,000-mile treadwear warranty, making it one of the longest-lasting rugged terrain tires on the market.

- How does the 3-ply construction benefit off-road driving?

The 3-ply high-turnup construction adds significant strength to the sidewall. This prevents punctures from sharp rocks and brush while providing better handling and stability when airing down for trail use.
