Reviews

Rated 1 out of 5 by from Not recommended worn out after 30,000 miles I really don't like providing negative reviews but for the fact that this tire is truly worn out at 30,000 miles. I regret purchasing them but when faced with a big decision like this I tried to do all the research and in the end at some point you just have to pull the trigger. I did with this tire and it's been two years 30,000 miles and set of four with full alignments rotations etc but they are done. I'm changing brands this time and again I'm left at the mercy of the rating and reviews so I guess I'll let you know how it goes in two more years. 2012 EcoBoost Ford f150 sensible driver over 40 years old, Haul equipment couple of times per year. just don't think it should have worn out already

Rated 5 out of 5 by from BUY THESE TIRES!! I planned to buy tires at a warehouse club a few years ago but stopped at NTB first, and I got a good deal on a set of RTXs. As it turned out, this was just before the worst winter in Boston history! These tires were great! Good responiveness and not too noisy on the highway, but aggressive enough for off road & deep snow. Even on unplowed roads I rarely had to engage 4WD. I regularly made 500+ mile round trip runs to Vermont (my daugter went to school there) & these tires had far better traction than the Michelin LTX tires that they replaced. Nothing beats the peace of mind of knowing that your car or truck can handle the worst driving conditions & won't leave you stranded. I like to be the guy that people can count on even when the conditions are bad, and the RTX makes bad weather driving fun. You really can't go wrong with this tire.

Rated 5 out of 5 by from Excellent Tire! When I was looking for tires for my Nissan Armada, I was looking for a tire that a great tire all around. I was not disappointed with this tire. Very quiet and smooth on the pavement , while still providing excellent traction and safety for my family. Off the road this tire is equally amazing! Providing excellent ability to take me almost anywhere I need to go. I think that there are other tires that could take me places that these could not, but I am not into any of the activities that would require the extra traction and durability.That is the only reason I gave those two a 4 out of 5, because a 5 in those categories is a tire that is much more expensive. The only other issue I will need to wait on is if the quality of the tread holds up over the long run and I will update on that as time goes on. I didn't get the LT's because my armada doesn't do a lot of towing and the things I do tow are light, nothing these tires can't handle, but I would recommend the LT's if you are towing anything large. Overall, for the average person that wants a great tire both on and off the road, this has been a great buy for me.

Rated 5 out of 5 by from Perfect tires for aggressive look on all terrain. Bought these tires for a Tahoe. Love the aggressive look and these are wearing well. Have over 20000 miles on the full set and no complaints. I'm planning to get a set on wife's Equinox soon. These tires are by far the best we have bought. Handles great in rain, snow, mud. Quiet and smooth ride.

Rated 5 out of 5 by from Still Smooth as ever after 9 months. I have a 2004 Lincoln Aviator AWD nothing to get excited about. 189,000 miles still runs great. still somewhat smooth. I Had these tires installed just B 4 last winter. they do provide very reliable grip in snow. I have to admit that these tires can be a bit rough starting out when the temps are around 20 degrees or below but they do smooth out as u drive. now that summer is almost here . these tires seem to ride very smooth with the warmer temps. Hope this helps. Thanks for reading.

Rated 5 out of 5 by from Great wear, handling on and off road. Got over 50000 miles out of the first set and handled all types of terrain we put it through. The beach, woods and normal highway driving. Just put a second pair on the truck a few weeks ago. Look forward to many more fun trips and miles.
