I think they're great! the BFG M/T's clean alot better but from my experience, they wear faster than the Firestones. I've got over 60,000 mi. on mine and have slightly more than 1/4in tread left. There's not alot of clay around here so I don't know about that. Farm fields, muddy riverbanks,snow drifts.they work really well IMO. some hydroplaning issues if you hit standing water at 60mph,but otherwise no problems there. I haven't been in too much sand either,but the little I have been in.. as long as you're easy on the skinny you'd be ok. But with a lead foot on soft sand you'd get burried quite easily. Good price,also.$545 OTD mounted,balanced valve-stems,31-10.5-15.I'm thinking of going to 33's when these wear out. Good Luck! I would reccommend them. And,yes. They're quiet,also.
