Re: Trip Report: Oregon Fall Adventures
The BFG M/Ts (35x12.5x15) on my Bronco are siped, and have lasted a long, long time (they're over 10 years old). Seen a lot of road use (dry and wet), but no snow on pavement. They have seen snow off pavement. Bronco weighs 4600lbs unloaded, probably close to 5000lbs loaded.
I completely gapped on getting my replacement tires on the SMB siped, otherwise I would have done it. You do need to make sure the tire warranty isn't voided by having them siped. FWIW, last I checked, America's Tire Company will sipe tires, though not every location had the machine.
SMB-less as of 02/04/2012. Our savings account is richer, but our adventures are poorer.
