BFGoodrich All Terrain T/A KO3 LT275/65R18 123/120S

The KO3 replaced the long-serving KO2, and if you are topping up a set on a truck wearing LT275/65R18 it is worth knowing they are different tyres rather than a rebadge. Mixing generations across an axle is best avoided; if only two need replacing, put the new pair on one axle together rather than splitting them.

Availability of the older tyre will thin out over time, which is the practical reason to plan a full set rather than assume you can match later.

123/120S supports 3,417 lb single or 3,086 lb dual at LT pressures, with an S rating to 112 mph - higher than the Q found on more aggressive treads and useful on a truck that covers motorway miles. Available to order at Rev Auto Club.
