“Cooper Discoverer AT3 4S discontinued, good alternative? I was hoping to replace my stock tires with the Discoverer AT3 tires since I hear really good things about them and they are a bit more aggressive. Seems like they are discontinued at all the normal tire shops online. So what are my alternatives for an AT style tire? Looking for 235/60R17 to put on Drag DR-31 rims. I live in CO so snow and some light off roading are things to consider. Read more”

“Thoughts on the “General Grabber A/TX” Tire? I’m thinking about getting it in a 33” SL rated 275/70r18. This tire comes in at 46Lbs which is super light. $915ish for 4! It’s the only 33”, snow rated, All Terrain, C/SL load range I could find. All the other 33”s are E rated coming in around 60lbs.”

“New tires 👌 cooper discoverer at3 4s 215/70/16”
“New tire day. Cooper Discoverer AT3 4S. So far so good. They ride great and they’re really quiet.”
“New tires: Cooper Discoverer AT3 4S Needed a 3PMSF tire and these Coopers edged out the Wildpeak AT3Ws based on wear rating and highway performance. Also, Cooper has a promo right now for a $70 mail in rebate. MPG has been about the same, maybe slightly better. Visually, I like them, more rugged than the stock Falkens. Highway and forest road driving has been solid. Stock size, 215/65R17, on a 2020 TH: Read more”

Community members frequently praise the General Grabber A/TX for offering a lightweight, standard (SL) or lower load range option in larger sizes like 33" (275/70R18), avoiding the heavy weight and harsh ride of E-rated alternatives. Drivers appreciate their aggressive tread, good snow traction, and ability to help conserve fuel economy compared to heavier tires. They are often compared favorably against competitors like the BFGoodrich KO2, Falken Wildpeak, and Nitto Terra Grappler.

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
