Review: Look good , handle so-so, hammered my fuel usage - I put these on a stock 2018 Ram 2500 Cummins. They look great but they also immediately dropped my fuel mileage by an average of 3.8 mpg on the highway with no load ,and I lost + 6 mpg when pulling a 30' rv trailer. These numbers were accumulated from my tuner ,using a stock tune over a 7 month period and compared to the avg mpgs when I was riding on the stock Firestones Review: Awesome tire for the price! - I use them on my off road/winter truck. I rotate through a set of 6 to keep them evenly worn, currently each tire has about 20k on them and tons of meat left. They are great off road aired down to about 12psi and I have yet to blow a bead out. They do alright in the snow on the road although I do drop the pressure down to 30-34psi for the winter. 40psi for the summer. ## Features - All-Season Commercial Traction Tire - Designed for tough terrain, including rocks and gravel, with on-road stability and performance - Tread design helps to prevent stone retention - Armor Tek3 construction for added tire durability - Cut and chip resistant tread compound/composition - Tires are studdable - Standard Limited Warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B006JYHDRO | | Brand | Cooper | | Brand Name | Cooper | | Construction Type | Radial | | Customer Reviews | 4.6 out of 5 stars 70 Reviews | | Global Trade Identification Number | 00029142720492 | | Included Components | Tire Only | | Item Dimensions | 21.4 x 83.4 x 28.5 centimeters | | Item Type Name | Tire | | Item Weight | 61.44 Pounds | | Load Capacity | 1700.97 kg | | Load capacity | 1700.97 kg | | Manufacturer | Cooper | | Manufacturer Part Number | 170066032 | | Maximum Pressure | 80 Pound per Square Inch | | Model Number | 170066032 | | OEM Equivalent Part Number | 54808 | | Ply | 10-Ply | | Rim Size | 16 Inches | | Rim size | 16 Inches | | Seasons | Year Round | | Size | LT285/75R16 126/123Q | | Speed Rating | Q | | Speed rating | Q | | Tire Aspect Ratio | 75 | | Tire Diameter | 25 | | Tread Type | Non-Directional | | Tyre aspect ratio | 75 | | UPC | 029142720492 | | Unit Count | 1 Count | ## Product Details - **Brand:** Cooper - **Seasons:** Year Round - **Size:** LT285/75R16 126/123Q - **Rim size:** 16 Inches - **Tyre aspect ratio:** 75 ## Images ![Cooper Discoverer S/T Maxx All-Season LT285/75R16 126/123Q Tire - Image 1](https://m.media-amazon.com/images/I/61sghwFM17L.jpg) ![Cooper Discoverer S/T Maxx All-Season LT285/75R16 126/123Q Tire - Image 2](https://m.media-amazon.com/images/I/812jwyQoewL.jpg) ![Cooper Discoverer S/T Maxx All-Season LT285/75R16 126/123Q Tire - Image 3](https://m.media-amazon.com/images/I/81kkhUwsgYL.jpg) ![Cooper Discoverer S/T Maxx All-Season LT285/75R16 126/123Q Tire - Image 4](https://m.media-amazon.com/images/I/61QbiECy1sL.jpg) ![Cooper Discoverer S/T Maxx All-Season LT285/75R16 126/123Q Tire - Image 5](https://m.media-amazon.com/images/I/51UH2nWH4ZL.jpg) ## Questions & Answers **Q: are these E rated 10 ply tires?** A: Cooper Discoverer S/T MAXX Radial Tire - 255/85R16 123Q - B00MXNLQEG.
