Cooper Discoverer SRX vs General AltiMAX RT43 — Compared

“I have used the Cooper Discoverer SRX, the Cooper AT3 4S and Michelin Defender LTX. The Defenders lasted until 75000 miles and of course towards the end they were getting noisy and losing grip like all tires. Its a stiff tire built for longevity but not ride comfort. The Cooper Discoverer SRX is a very comfortable tire, but I got like 40000 miles out of them. They didnt seem to last. I am now using Cooper AT3 4S and its a very comfortable tire. It is a quiet tire but only a slight tolerable hum on the highway most wont notice. I cant believe its an all terrain tire. Thus I found long lasting does not translate to ride comfort. When you have a truck you need to hit the bumps more gently. The Coopers are comfortable tires which will make you turn your truck into a car but they are not 75000 mile tires. The Michelin Defenders will leave no doubt you driving a truck. For comfort also look at Continental/General line...”

“We'd gotten Coopers on Wife's vehicle and were impressed, so I tried Discoverer SRX 245/65/R17 on our Honda Ridgeline truck and they were (and remain) a revelation at least in that they made a huge difference in quieting the road noise. This was 7 years ago and now 30,000+ miles later they still look as new with little noticeable tread wear. Dunno the HTP or ATP II versions but imo Coopers are/can be first-rate tires.”

“I just put the Cooper SRX on my 2013 Overland, nice and quiet so far. The snow has been easy too, I don't foresee having any problems with these tires, glad I got them.”

“Quite disappointed with Altimax RT43. They only lasted 62250 km before wearing to the wear bars, and driving on highway in a rain was scary for the last season or two. Driven April - November only. The winter set is studded Nokian Hakka 8 SUV - those are excellent. Getting Michelin CrossClimate 2 installed tomorrow at Costco .”

“I have the General Altimax RT43 on 19s as my winter tires, and they are perfectly fine. For sure louder than oem, because there is no foam, but for wear, tear and handling, perfectly fine. I am not racing anyone or driving aggressively with those tires on anyway.”

“General Altimax RT43's are absolutely amazing. I live in Minneapolis, MN and all I can say is they are amazing. Sidewalls are a little bit thin and can lead to some body roll on the cloverleaf. I bought another car and wanted something a little more sporty looking and I have to say Discount Tire's Yokohama YK740 GTX has also been amazing in all weather, however with just a bit more lateral slide in icy conditions. If you want to just simply move in any weather, either of these are tires fantastic.”
