OTHER TIRES TO CONSIDER
Great Performance!
My first "highway tire" on this vehicle. I love the quiet and smooth performance at 70-80 mph. At 20,000 miles they show little wear.
Pleasantly Surprised Former Mich**** Customer
I've been a Mich**** fan my entire half-century life, but became disillusioned with their value in recent years. so I bought these tires for my pickup. It helps that all the guys at my independent local dealer have them on their trucks and their sons' trucks, etc. That's good enough for me. I've run these now for almost a year, and am VERY pleased. They are smooth, quiet, sticky, and look nice too. I'm about to put a set on my daughter's CR-V.
Another Happy Customer
I bought my 1st set when these were first released forms 2005 Duramax. Loved them from the start. Oregon wet roads they performed great, hauling my 40' 5th wheel out on the Pismo sand aired down, and snow too. So, in 2019 I added them to my 2017 Ram 3500. Again, still happy with the way they wear, ride, and perform. They continue to handle the wet winter roads, very occasional snow, and hauling the heavy weight of the 5th wheel. As they are on my daily driver, I rotate every 5k miles, and have no issues. Toyo tires have always been my go to, and as long as these are available, they will be my go to!
Best Longevity & Performance Thus far
I purchased a set of Open Country R/T 37x12.50xR20 for my 2016 Ram 3500 Mega Cab SRW back in February of 2019. I have put 80,000 miles on these tires. I have pulled my 43' fifth wheel all over the south as well as equipment. These tires have continued to impress me. I feel I could get more out of them but I have wheel bearings going out in the front that have caused them to start to wear uneven. The only draw back I have is the fact that it takes 3-4 months to get these tires from every dealer I have contacted. With Covid-19 hitting last year I have been unable to pre-order the tires due to financial reasons. Now I am at the point where I have to have a set and no one has them.
Love The M/T
modified my jeep with 35x12.5x20's these Toyo M/T handle great, look awesome and am very impressed with the way they've held up. 55k and going. definitely will replace with them again my previous jeep had them as well - same experience!!!
Excellent Mud/Rock/Street Tire
I bought these tires (37-13.50-R17) hoping for the best. I knew when the tire shop balanced them they were going to be great. It took very minimal weight to balance them. The guy said they were as round as a Michelin street tire. They are awesome! I rotate every 3000-3500 miles. I have 25K miles on them and they look great. No doubt I'll get 60K+ out of them. I use my truck for daily driving, work and off road. They worked flawlessly on the trails at Uwharrie National Forest and others. You will not be disappointed!
Overall Completely Satisfied
My personal opinion is that on HD pickup the mileage and durability are great
Heavy Duty
There isnt much on the internet about these tires so hopefully I can help. I've had them on a 2017 diesel super duty for 8000 miles, mixed driving. They currently have 14/32 tread. These tires will last over 50k miles under this heavy truck. The Michelin tires were sucking up nails twice a week (I work construction) and these tires have not gotten a single nail in the few months I've had them. PROS: Long life. Look great. Tough tire. Great traction, in all conditions. Balance well. Quieter than a mud tire. CONS: Wrecked fuel mileage (2-3 MPG decrease, both highway and city). Ride like they are wooden tires. Very heavy (definitely do not recommend for a half ton or lighter truck). Noise level is similar to noisy ATs, but not as loud as MTs. In summary, if you value durability over all else, I recommend this tire. If you drive the family around as much as you work in your truck and value comfort and/or fuel efficiency, shop for a regular all terrain like everyone else does. My previous AT tires were AT3 XLTs and they were significantly more comfortable and efficient, and I will probably go back to them, if these tires ever wear out.
