Dunlop  Grandtrek AT20

With 4100 miles these tires have been good so far. Good dry traction, ride comfort, and steering response. The wet traction is good, however the hydroplaning resistence is just so-so. I imagine Ill be avoiding water puddles like the plague whenever the tires have worn down a bit. As far as noise comfort they seem to be pretty quiet, although I have undercoating on my truck and the Tundra is a quiet truck anyway.

I bought this 2006 Tacoma New. Came with the Dunlop Grandtrek AT20. 245/75R16. These tires have been the best I have ever owned in my 24 years of driving. They handled fantasic. I have done some pretty fast highway driving. Cornering was great. Moving in and out of city and high way traffic was quick and responsive.

I took the truck when I first purchased it on a trip back to Tennesse. 4300 miles. Had to drive across the lower postion of Missouri; 450 miles in a torrential down pore of rain. Passing trucks that were going 50 or less with an off spray of water coming out from the semies tires. Needed to pass or do 50 for who knows how long. So hung on tight and pasted quick at about 70mph with no problem at all.

These are great tire and I highly recommend them.

My experience with these tires has generally been good. They provide very good dry handling, responsiveness, low noise and good ride quality. In the rain they are about average and snow traction is ok but nothing to write home about. I only have 12,000 miles on them and they seem to wearing fairly quickly (but evenly) which is a surprise since Im very careful about alignment and pressures. Id guess they are a soft compound tire which helps explain the good dry handling. If they make it past 45,000 miles Id consider buying another set, if not Ill look else where.

I'm not sure why these tires get such a bad rap. I've got 30500 miles on my 4Runner and they are very comfortable on the road, quiet on the highways, have never let me down on dirt trails and mild off roading. They also did fine the few times we've had ice and light snow here in metro Atlanta as long as I did my part. In those conditions drive like your grandmother is in the back seat holding a hot bowl of chili... Tread life is good, the edge tread is showing a little rounding but that's to be expected. They are definitely not a hard core mud tire (and shouldn't be judged to that standard) but Toyota picked a winner as an OEM offering.

These OEM tires are quiet and comfortable. They probably help with fuel consumption. None of those are reason why I bought a 4Runner. I mostly drive my truck in the winter and these are really pathetic in the snow. Living in one of the snowiest areas of the US, I always run dedicated winter tires on any vehicle I drive in the wintertime and I usually wait until snow accumulates before I switch over. The AT20s come off as soon as there is any snow.

Long story short, if you can only have one set of tires on you vehicle and plan on encountering ANY snow, these are NOT the tire for you.

These also came OEM on my vehicle and it is not doing to well in my break-in period. It is very smooth and comfortable and all, but the braking and the road handling responsiveness is terrible. Even with four ventilated disc brakes, I felt that my old Xterra (drums in the back) on Geolanders AT +II did much better.

My 2020 4Runner came with Dunlop AT20s from the factory. After just 3,000 miles, I can confidently say that these are the worst tires I have ever had on any vehicle I have owned. They may wear well but the wet traction is abysmal and the resistance to hydroplaning is non-existent. Michelin Defenders with under 3/32" tread perform better in wet conditions than these tires. I knew these would not suffice for winter in the Rockies but considered keeping them for summer. After hydroplaning down Vail pass in a light thunderstorm, I've decided these tires are better suited for the trash dumpster than any driving condition.

These were the stock tires on my Tacoma. They lasted approx 52K miles which is good. However in any sort of wet they were awful. I switched tires before the snow hit but given their performance in the rain, I wouldn't have gotten very far in the snow.

Have seen glowing reports, which I find incredible. One unfavorable review notes that rain makes the owner scared to death in this tire. I have the same reaction. When it rains, I go immediately into 4 wheel drive, and creep around turns and into stops. Its worse than driving on ice. Dunlop should look into hydroplaning problems. Ive had 2 jeeps, a pathfinder and this 4 Runner and never had this problem before. Have had numerous serious close calls even just after buying the car, and recently an accident. Although tires look in good condition, Im replacing them. Toyota should be shot for making these tires original equipment.

I cannot believe Lexus would put these crappy tires on a 50k SUV. I almost was killed becuase of the terrible snow/wet traction. I just got Bridgestone Revos and WHAT A DIFFERENCE! These tires should be banned!

Performed well for first 15K, then went downhill quickly. Bad traction on sharp turns. No traction in snow last winter. Tread gone on tire edge even with proper inflation and regular rotation. Trying Yokos next.

These tires came on my 4-Runner, I cant believe Toyota put such a horrible tire on an otherwise great vehicle. Traction for the first 5,000 miles was average to good. However, around 7,500 or so, things went down hill fast. Dry traction got worse, and then the snow started to fall. The tires are horrible in the snow, slush, and ice. They do ok in a light snow (less than and inch or two), but even then, they are unpredictable. They also form flat spots if you are parked for more than a day or two. Takes about 5-10 miles of highway driving to iron out the flat spots.



Will never buy these tires again, and as soon as Ive got the money set aside I plan to buy replacement tires, even though there will still be tons of remaining tread on the tire. They are just that bad.

OEM tire. Very poor tread life; down to 2/32 after only 30K / 20 months. Became 'squirmy' late in life. Surprisingly good snow/ice traction when on an AWD vehicle.

Tread life is nowhere near a 60000 mile tire. I will be lucky to see 30000, with normal driving. They came on my Toyota Tacoma when I bought it. I will but something else when I replace them.

This tire was the original when I bought the Sequoia. I am extremely disappointed. At about the 15,000 mile mark; my front tires were almost bald! Now, at just shy of 20,000; I need to replace the front tires and unfortunately, one rear tire as I have a side wall tear. The Sequoia has not yet been off rode and the only thing I have 'towed' are 5 elementary school kids for carpool! I am extremely disappointed in the tire and Toyota for choosing such an awful tire.
