Bought these as replacements to the OEM rugged trails and the rugged terrains are so far, far superior. Wet and dry traction is superb on highway and I use my truck off road in the woods around the house to tow a firewood trailer, cross horse pastures, and travel plenty of dirt/gravel country roads. I would say the truck is actually smoother with these on vs the R Trails's and possibly even quieter, but that might be due to the mileage on the R trails which I replaced at 30K. I did not want to venture the winter with the remaining tread on those. We should be getting some light to mod snow around Christmas and am looking forward to seeing how the Rugged Terrains do in the white stuff. And we'll be taking the tacoma down the OBX again this summer and i'll get to test these in the sand. The R Trail's managed OK this past trip to the beach, even allowing us to pull out a stuck Tacoma & a range rover, but I think that was mainly due to the Tacoma's 4 wheel drive systems. But the perfect application should come in September when I need to drive the truck from the east coast to Colorado and then up into the mountains for an Elk hunting trip. BTW, at 70 mph on the interstate, these tires run very smooth and quiet with no vibration or chatter...If your experiencing this I would take them back to the shop for a re-balance and get your shocks and alignment checked, its not the tires, unless in the very rare case you got one with a broken radial, which I have experienced with another Brand, but not with BF Goodrich. I hope Michelin lets BF G continue to put out the quality they have in the past... I used to run BFG AT's on my old truck and never had a problem at all, but since I'm now using this truck as a commuter and weekend off roader, the rugged terrains seems to be the perfect solution so far.
