Product Description
The Goodyear Wrangler Authority A/T is built for truck and SUV owners who want genuine on- and off-road capability without stepping up to a full mud-terrain tire. This 275/55R20 113T size brings a rugged, staggered tread design with large center tread blocks and self-cleaning shoulder blocks, engineered to grip dirt, gravel, and mud while still delivering a smooth, controlled ride on the highway.
Zigzag microgrooves add traction across a range of weather conditions, including rain, snow, and ice, while the rugged tread rubber is formulated to resist chipping, chunking, and tearing from the kind of abuse off-road driving can dish out. Integrated rim protection helps guard your wheels against curb damage a small but genuinely useful detail for a tire this size, where wheel and tire costs add up fast. This particular P-Metric size does not carry the 3-Peak Mountain Snowflake severe-snow rating (only LT-metric sizes in this line do), so while it handles typical wet and light winter conditions well, it isn’t certified for severe snow performance.

Frequently Asked Questions
Is this tire rated for severe snow?
No this specific P-Metric size does not carry the 3-Peak Mountain Snowflake designation. Only the LT-metric sizes in the Wrangler Authority A/T line are severe-snow rated. This size still performs well in rain and light winter conditions thanks to its zigzag microgrooves, but it isn’t certified for heavy snow performance.
What does the “113T” mean on this tire?
113 is the load index, indicating the maximum rated weight the tire can carry per tire at full inflation, and T is the speed rating, covering sustained speeds up to 118 mph under proper conditions.
Is this a good tire for light off-roading?
Yes it’s designed as an all-terrain tire with a tread pattern built for dirt, gravel, and mud, striking a balance between off-road capability and comfortable, quiet highway driving. For serious rock crawling or deep mud, a dedicated mud-terrain tire would outperform it.
Does rim protection actually help prevent wheel damage?
The integrated rim protector adds a raised guard along the tire’s edge, which helps reduce the risk of curb rash and minor impact damage to your wheels compared to a standard sidewall design.
Will this tire fit other full-size trucks and SUVs beyond the confirmed list?
275/55R20 is used across a range of full-size trucks and SUVs beyond the models confirmed here — always check your vehicle’s exact factory or approved replacement size before ordering.
