Stay away from the Cooper Stt.Friend has them on his 2006 F-150 and hates them.Only had them a year and not even half tread is left.All this from mostly street driving.He has only been mudding 4 times in the last year.Also for hyped up for a mud tire.My Duratracs performed better than his Stt's in the mud. Went mudding together 2 weeks ago.Same ruts,same pits.I was in 2wd and getting thru them just fine.He tried 2wd and didn't make it thru half of what i did.So he had to switch to 4wd.Now this is just my opinion.Others may differ.
Well I havent personally owned either cooper st's or stt's but the welding truck I drove last summer had the st's on it and they were great in mud and wore great too and that was a 1 ton with a flatbed, welder, and tons of tools on it. My boss was talkin bout the stt's though and he said the only set he'd ever seen with decent tread on em were brand new... We also had a set of bfg mt's on 1 weldin truck and they were just plain badass
i like the terra grapplers but i want a mt. the trail grapplers look bad but i dont really have that kind of money.
