Results
The results below are derived from the 2022 Bob Jane T-Mart’s All-Terrain (AT) Tyre Comparative Test. A total of 9 tires were tested this time, with the OE Bridgestone Dueler A/T 697 set as the reference point. The following graph compares the Yokohama Geolandar X-AT vs BFGoodrich All-Terrain T/A KO2 based on their relevant performance categories. The Yokohama Geolandar X-AT was set as the reference, hence at the 100% mark. Note that for subjective evaluations, we equate 1 point to 5%. Thus, for example, if tire A is graded 7 while tire B is graded 6, tire A is considered 5% better than tire B.
In the all-terrain segment, off-road tests are undoubtedly essential and cannot be overlooked. This time, the off-road test consisted of a mix of mud, gravel, and loosely packed sand. The tire size of interest is 265/65 R17, which is a common size for vehicles such as the Toyota Hilux and Ford Ranger. You can refer to our latest tire size table for more information. The chosen testing vehicle for off-road performance was a 4-wheel-drive Isuzu D-Max.
Offroad
Featuring large grooves that offer significant void volume, the All-Terrain T/A KO2 showcases impressive off-road capabilities, securing the highest score among competitors with 22 points. In contrast, its fierce rival, the Geolandar X-AT, only managed to achieve an 18-point rating, as it fell short in off-road traction and comfort compared to the All-Terrain T/A KO2. If you’re searching for an all-terrain tire that excels off-road, the All-Terrain T/A KO2 is undoubtedly your top choice.

Wet
In terms of wet performance, all-terrain tires typically boast a deeper tread depth, allowing them to disperse water more efficiently. However, there is a noticeable disparity in wet braking among competitors. While the All-Terrain T/A KO2 excels in off-road capabilities, the Geolandar X-AT outperforms it in wet braking performance. Impressively, it managed to stop 3.3 meters earlier than the All-Terrain T/A KO2 when braking from a speed of 80 km/h (50 mph). Surprisingly, the All-Terrain T/A KO2 performed quite poorly, as it placed last in the test with a maximum difference of 9.8 meters between itself and the top wet braking tire. The test also included braking trials from 60 km/h and 100 km/h, with the difference in braking distance between the two tires widening as the speed increased. Based on these wet braking test results, the Geolandar X-AT clearly outshines the formidable All-Terrain T/A KO2, as it performs 10% better in wet braking.

Dry
In dry conditions, safety is generally not a major concern, as braking distances are longer than in wet conditions. However, since this represents standard daily usage, tires must deliver consistent performance. The Geolandar X-AT managed to outperform the All-Terrain T/A KO2 in dry braking, stopping 3.6 meters shorter when decelerating from 100 km/h (62 mph) to a complete stop. With limited surface contact and a large block pattern, the All-Terrain T/A KO2 recorded the worst dry braking performance among the nine competitors.
The trend was reversed in the dry slalom test, where the All-Terrain T/A KO2 held a subjective advantage, scoring 11 points compared to the Geolandar X-AT’s 8 points. In the lane change test, the Geolandar X-AT took the lead once again, finishing with 12 points compared to the All-Terrain T/A KO2’s 11 points. Based on the dry performance test results, it’s evident that the Geolandar X-AT was better in dry braking and lane change, while the All-Terrain T/A KO2 was superb in dry slalom.

UTQG rating
We have previously shown that UTQG tread wear rating can be a good indication of your expected mileage. Below are the UTQG values of both of the tirelines.
| Brand | Tireline | Size | Mileage Warranty (miles) |
|---|---|---|---|
| Yokohama | Geolandar X-AT | All | 45,000 |
| BFGoodrich | All-Terrain T/A KO2 | All | 50,000 |
Unfortunately, since both the All-Terrain T/A KO2 and the Geolandar X-AT are sold with a light truck (LT) designation, they do not need to provide any UTQG ratings. However, we can gauge the expected mileage from the mileage warranties of both products. The mileage warranty of the All-Terrain T/A KO2 is higher at 50,000 miles, while in comparison, the Geolandar X-AT has only a 45,000-mile mileage guarantee. With these numbers, we can safely assume that the All-Terrain T/A KO2 has a slight edge in mileage compared to the Geolandar X-AT.
Price
BFGoodrich, a premium brand owned by Michelin, is often considered one of the most expensive options in the all-terrain segment. However, based on the prices we surveyed, this assumption was proven to be untrue, as the Geolandar X-AT is surprisingly $7 more expensive than the All-Terrain T/A KO2.
Tire size: LT 265/70R17
Geolandar X-AT : $283
All-Terrain T/A KO2 : $276
Difference: -2.5% more cheaper for All-Terrain T/A KO2.
Summary
In summary, both tires excel in different performance criteria. The Geolandar X-AT excels in both wet and dry braking, while the All-Terrain T/A KO2 outshines in dry slalom and off-road capabilities. In this head-to-head comparison, it’s difficult to declare a definitive winner, as both tires excel in distinct performance areas. The key to selecting the right tire lies in your individual preferences and priorities when choosing your next set of off-road tires. If off-road performance ranks as your top concern, the BFGoodrich All-Terrain T/A KO2 would be an ideal fit. Conversely, if wet performance is of the utmost importance, the Geolandar X-AT would make a perfect match.
