On-Road; Radial Longtrail T/A, 80%-20% on-off

"An all-weather, all-season, tubeless radial tyre. It is available in original equipment sizes and speed ratings for sporty and urban 4x4 vehicles. The sophisticated polyester casing is crowned with a distinctive double steel-braced asymmetric tread. The whole tread surface is extremely well siped to give extra mobility in snow". 

Mixed; All Terrain T/A, 50%-50% on-off

"Built specifically for on and off road traction, BFG have redesigned America's favourite off road tyre to deliver even more 'go anywhere' traction and vastly improved durability and wear. It gives you the confidence and control to tackle roads rocky or smooth, while our legendary 'TriGuard' three ply sidewall construction (most tyres have just two) delivers exceptional strength and toughness. The best just got better".

Off-Road; Radial Mud Terrain T/A 20%-80% on-off

"This is the ultimate tyre for freedom and mobility off the road. The casing is of 'TriGuard' construction - three polyester layers - which is extremely strong and resistant to damage. The tread has been designed to pull your vehicle through the very worst off road conditions, including mud, rock, snow or sand. On the road the level of comfort is remarkable for such an aggressive tyre designed primarily for off road use".

Perfect illustrations of just what to look for in tread design for off road grip in varying degrees!

Note though that these tyres are not particularly highly rated for speed or load.
