I bought these as a joke but ended up using them on my Nissan Titan Crew Cab 05 2WD Short Bed. God bless me if they didn't work perfectly. I have factory wheels and tires and they fit perfectly with little clearance (265/70R18 116T), they probably won't fit anything bigger. I put them on before we drove to Echo Lake near Tahoe, California and they held me tight and didn't slip. I highly recommend them for light snow and ice, but I wouldn't advise thinking that they will take you beyond the capabilities of 2WD in general. Excellent purchase. I also don't expect them to last many times when you have to put them on many miles.
