A few tires that got my attention at the 2016 SEMA Show.
Cooper STT PRO 40”
We really live in a super-sized America, maybe world? Tires that would have been almost monster truck worthy a few decades ago are now produced in highway-rated, easy to balance radial designs. Cooper introduced their fantastically rugged, yet tame on-road, Discoverer STT PRO in a new 40×13.50R17LT size.
Cooper has manufactured 40” tires for subsidiary and private label brands; however, this is the first to wear the flagship Cooper name. Two other big sizes were introduced, the 38×15.50R18 and 38×15.50R20. As sizable as these may sound, 35×12.50” tires can be fitted to Fourth Generation Ram Cummins Turbo Diesels with no lift, stock wheels, and only minimal rubbing. coopertire.com
Mastercraft Courser CXT
This past summer Cooper subsidiary Mastercraft introduced their latest commercial traction tire, the Courser CXT. The CXT features: variable full-depth siping, silica-rich compound for wet/winter traction (M+S rated), large scallops on the outer lugs and generous sidewall shoulder rubber. They are available in 29 sizes, each with a generous 18.5/32” tread depth. A friend and I have been logging miles on a set, accumulating wear data from two Ram/Cummins trucks. mastercrafttires.com

Mickey Thompson introduced the Deegan 38 All-Terrain for wheels from 15” to 22”. Twenty-nine sizes are available now, with two more coming in April, and the final two sometime in the second quarter of 2017. Light-truck sizes come with a 55,000-mile tread-wear warranty, and P-metric sizes have a 60,000-mile tread-wear warranty. Mickey Thompson says the new design features a “silica-reinforced compound and special siping for great traction, superior cut and chip resistance, and excellent handling and braking in wet and off-road conditions. Tread element tie bars enhance stability and responsive handling on changing road conditions. Angled shoulder scallops and aggressive two-pitch SideBiter’s enhance traction.” mickeythompsontires.com
Nitto Ridge Grappler
The newest LT design from Nitto looks like a winner. A hybrid all-terrain with traction lugs for the outer ribs and a slightly lower-void center, it looks like noise should be well controlled. The shoulder tread is beefy, and, as with all Nitto LT tires, there is a different design on each side; you choose. Several sizes are made for 17” to 22” wheels. nittotire.com
Manufactures are offering enthusiasts traction tires that are much quieter and less aggressive than mudders but with superior all-weather traction characteristics over a traditional all-terrain or all-season. Toyo eliminated all doubt about the target market by putting it right in the name; C/T stands for commercial traction. The Toyo Open Country C/T was originally only available in Canada, but it was released for sale in the USA in 2016. The C/T meets the mountain snowflake/Alpine severe winter spin-up test requirements. toyotires.com
