Anybody know when BFG last updated the All Terrain design? I have a set of 5 BFG ATs 33X12.50-R15. Two are worn out, 2 have 50% treat and 1 almost new (it was the spare - lol). So to have 4 tires that will pass inspection I found a matching tire (so I thought!) on CL. Almost new and seller claimed it also was a spare and never on the ground. The tire is in really good condition and has close to 100% tread - looks like it may have been on the ground once or twice. I'm not complaining about the tire condition - it still has the "blue" on the white letters, but I am questioning the age of the tire. The set of 5 I have are probably about 5 years old and they say "All-Terrain T/A" and the tire I bought supposedly newer, say "Radial All-Terrain T/A". Plus the new tire has a less agressive side lug design. Not much but definately less agressive. The ATs on the BFG website say "All Terrian T/A" - no "radial" in the raised white letters. So, can anybody tell me the difference between an AT that says Radial All-Terrain T/A vs. an AT that simply says All-Terrain T/A?? Both are radials!
