Our verdict on the Cooper Discoverer ATP II
Price-to-performance is the Cooper Discoverer ATP II's strongest axis at 8/10, with quiet, settled highway manners next at 7/10 and a 6.6/10 blend as an all-terrain. Nothing in the profile collapses: the lowest mark, mud clearing at 4/10, is 4 points off the top and does not even feed the blend, and the dataset flags it when a 3PMSF severe-snow rating is required. It stops at the M+S marking rather than the 3PMSF symbol; as a mid-priced option it sits at #9 of 50 overall and 6th of 18 all-terrains, is catalogued in 8 Tacoma sizes on 16- through 18-inch wheels, and rests on 3 cited sources. Its lead use cases are budget daily driving and light trail and gravel, one place behind the Yokohama Geolandar A/T4 in our ranking.

| Axis | What it covers | Score | In blend |
|---|---|---|---|
| Road comfort | pavement ride quality and noise | 7/10 | Yes |
| Wet grip | traction on wet pavement | 7/10 | Yes |
| Snow | packed snow and winter road traction | 5/10 | Yes |
| Trail | dirt, gravel, and rock trail traction | 6/10 | Yes |
| Mud | deep mud traction and self-cleaning | 4/10 | No |
| Durability | puncture and sidewall resistance | 6/10 | Yes |
| Tread life | expected mileage before replacement | 7/10 | Yes |
| Efficiency | weight and rolling resistance | 6/10 | No |
| Looks | how aggressive the tread and sidewall read | 6/10 | No |
| Value | what the tire delivers per dollar | 8/10 | Yes |
7 of the ten axes feed the blended number (road comfort, wet grip, snow, trail, durability, tread life, and value); mud, efficiency, and looks are shown for the Cooper Discoverer ATP II but sit outside it, which is why a mud or looks score can run well above or below the headline.
Who the Cooper Discoverer ATP II is for
Best for
The research dataset tags the Cooper Discoverer ATP II for the uses below; the number after each one is the axis in its own profile that backs the tag.
- Budget daily driving — value 8/10.
- Light trail and gravel — trail 6/10.
- Retailer-exclusive value — value 8/10.
Avoid if
The same dataset flags where the Cooper Discoverer ATP II is the wrong pick, again with the axis behind each call.
- A 3PMSF severe-snow rating is required — snow 5/10.
- Maximum rock durability is the priority — durability 6/10.
Tacoma sizes the Cooper Discoverer ATP II comes in
The catalog behind this dataset records the Cooper Discoverer ATP II in 8 sizes that fit common Tacoma wheel diameters, spanning 16-inch, 17-inch, and 18-inch wheels. Of those, 7 have a Tacoma fitment page on this site, linked below.
Those 8 entries are the dataset's own availability list for the Cooper Discoverer ATP II, not a live retailer feed — a model with a thin catalog gets a short list here rather than a padded one. What actually clears on your truck still depends on wheel width, offset, and how much trimming you will accept, so check the size against your generation before you buy.
Sources behind the Cooper Discoverer ATP II's scores
The Cooper Discoverer ATP II's row rests on 3 of the 83 cited documents behind this research set — retailer recommendation, tacoma category guidance, and retailer product. Each is listed with the date it was read.
Cooper Discoverer ATP II on a Tacoma: common questions
In our editorial synthesis the Cooper Discoverer ATP II blends to 6.6/10 across the seven all-round axes, which places it 6th of 18 all-terrains and #9 of 50 in the whole research set. Its case rests on value for the money (8/10) and quiet, settled highway manners (7/10), so it suits budget daily driving, light trail and gravel, and retailer-exclusive value.
The research catalog records the Cooper Discoverer ATP II as offered in 8 sizes that fit common Tacoma wheel diameters: 265/70R16, 265/75R16, 265/65R17, 265/70R17, 275/70R17, 285/70R17, 265/65R18, and 275/65R18. That is the dataset's own availability list rather than a live retailer feed, so confirm the exact size and load range with the seller before ordering.
The Cooper Discoverer ATP II carries the M+S marking but not the 3PMSF severe-snow symbol, and our synthesis scores its snow axis at 5/10. If your state or your commute requires a severe-snow-rated tire, this is not the row to pick.
The weakest marks in the Cooper Discoverer ATP II's profile are mud clearing at 4/10 and snow traction at 5/10. The dataset flags it as the wrong choice when a 3PMSF severe-snow rating is required and maximum rock durability is the priority. Those judgements come from the 3 cited sources listed on this page, not from anything measured here.
