“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”

Pros, cons & observations

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.

Tire A Discoverer A/TR

Pros

  • Remarkably low road noise for an all-terrain tire with a deep, chunky tread.
  • Excellent wet weather performance and resistance to aquaplaning.
  • Long-lasting tread life with high mileage capabilities (some users exceeding 50,000 to 80,000+ kms).

Cons

  • Some instances of severe edge chipping and cuts to the steel when used on rough outback gravel roads.
  • Tramlining effects in the steering as the tires wear down.
  • Off-road capability diminishes noticeably as the tread wears past a certain point.

“Cooper Discoverer AT3 4s I am struggling to find Cooper Discoverer AT3 4s tyres with size 265/70/17. There seemed to be an acute shortage in the market. I am not keen on BF Goodrich due to the weight and price. I shall appreciate it if anyone with reliable leads for Cooper tyres. What else do you recommend if Cooper is just not realistically available? I can wait till March before I need to get my car tested for renewal of registration. TIA.”

How do we compare tires?

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.
