All Terrain vs Mud Terrain vs RT Tires

A/T All-Terrain Tires

A/T all-terrain tires are usually the default go-to for most 4×4 enthusiasts that still regularly use their vehicle on the street. They are the most economical off-road tire choice and they typically last longer than the other tire options. You can find all-terrain tires under everything from small Jeeps to 1-ton dualie tow rigs. A/T tires are generally the lowest cost and lightest of the three tire types when looking at equivalent size and load ratings. They also offer the least rolling resistance of the three, which helps provide the best fuel economy as well. All-terrain tires usually feature a more durable reinforced tread and sidewall than traditional all-season street tires and they offer more traction on slick surfaces. All A/T tires have a M+S mud and snow rating and many are shod with the exclusive three peak mountain snowflake rating for superior ice and snow performance. This is a key rating to look for if you frequent winter roads regularly.

M/T Mud-Terrain Tires

M/T mud-terrain tires are generally not for the meek or faint of heart. They feature large knobby tread lugs and open voids that help move mud and offer traction in difficult terrain. However, on-road they are loudest and least efficient of the three tire types. Because of the meaty tread and sidewall lugs, mud-terrain tires are often the heaviest tire option. They are also the most expensive option. Mud-terrain tires are prone to wear out more quickly and unevenly than other tire types and are the most difficult to keep properly balanced. All M/T tires have the M+S snow rating, but the large smooth tread lugs offer poor performance on ice and wet roads, even if they have siping. Now, if you regularly encounter clay mud or simply like the aggressive looks of a mud-terrain, these are the tires to have. Their fantastic performance in the wet stuff is only matched by their mediocre performance and handling on-road.

R/T Rugged-Terrain Tires

The R/T rugged-terrain is a relatively new tire design and designation. R/T tires are sometimes called tweener tires because their on- and off-road performance and tread aggressiveness fits in between the A/T and M/T tire types. As such, R/T tires generally offer both A/T and M/T tire features, such as large open voids and knobby sidewall tread to help move mud as well as siped tread lugs to improve traction in wet and icy conditions. All R/T tires have the M+S mud and snow rating and some also have the coveted three peak mountain snowflake advanced snow rating, making them a great choice for vehicles that see street use, icy roads and unimproved snow and mud covered trails. R/T tires can be used successfully on all types of 4x4s from small SUVs to 1-ton tow rigs.

BFGoodrich All-Terrain T/A KO2

The BFGoodrich All-Terrain is an A/T tire that has been a staple in the 4×4 world for many decades. The latest KO2 version still carries that flag. The all-around performance on- and off-road makes it a great tire for a daily commuter 4×4 that acts as a weekend warrior too. It’s also a favorite tire for overlanders. The BFG all-terrain KO2 features a three peak mountain snowflake rating, which provides superior winter performance over a traditional M+S mud and snow rated tire. It’s available in many popular sizes up to 37 inches.

Pros:

• Great all-around performance
• Three peak mountain snowflake rating for severe winter conditions 

Cons:

• Can wear out faster than some other all-terrain tires on heavy 4x4s
• The small sipes in the tread can capture and hang on to small stones
