Taking a Closer look at Cooper Tires

Cooper CS4 Review

Cooper tires are replacement tires (non-OEM) and offered primarily for cars, SUV, and Crossovers. Cooper put about $200 million into the research on the rubber to create the CS4, and it really paid off.

This is Cooper's first tire to incorporate R-Tech design. This design is said to provide for even tread wear, and to extend the thread life of the tire.

Cooper tires are replacement tires (non-OEM) and offered primarily for cars, SUV, and Crossovers. Cooper put about $200 million into the research on the rubber to create the CS4, and it really paid off.

This is Cooper's first tire to incorporate R-Tech design. This design is said to provide for even tread wear, and to extend the thread life of the tire.


Cooper Tires CS4Nylon wraps expand and contract with change in the temperature of the road. This makes the tire more rigid (when the road is hot) for better traction. R-Tech also has a wider arch and grooves that are much wider. This improves traction for wet driving conditions.

You can find the CS4 with two different tread designs. The first is the T-Rated (up to 118 MPH) design called the Four-Rib. The Four-Rib has a larger 'acua channel' running down the center of the tire.

The second tread design is the H/V Rated (up to 149 MPH) design called the Five-Rib which has two acua channels, one on each side of the center rib. Each tread design uses a silica tread for greater resistance to hydroplaning.

Tests performed by MotorTrend showed the Cooper CS4 tires stopped better than the Continental ContiTour tires (10 feet better) that were stock on the test vehicle. Tests results from Cooper were similar at 10-12 feet. These tests were done under wet conditions.

Under wet conditions the CS4's really shine.

Track tests against Michelin Harmony are said to be noticeably better with much more stability and greater traction. The T-Rated version of this tire is quoted as being 'less capable', but has that nice 80K mile warranty from Cooper Tires.

Price on these are from $60 to $120, so shop around for the deals and discount tire coupons.


  • Quiet and smooth ride. Comments in reviews of these tires state overwhelmingly that they are very quiet.
  • Great performance tire in dry and wet road conditions. In wet weather the Cooper CS4's really set themselves apart.
  • For All-Season tires the CS4's perform exceptionally well in light snow conditions
  • Many reviewers have stated that the CS4 are like 'riding on air'.


  • For some reason, the H/V rated CS4's can be hard to find. People really love these tires.

Final thoughts from tire-reviews-online.com:

CS4's are highly regarded by consumers that have owned them, as well as by the pros that have tested them. If you're looking for a tire that provides a very quiet and smooth ride, these may be your ticket.

It was hard to find many negative comments about this tire, and the ones that complained were not worth mentioning. If you are an aggressive drive you should get the Four-Rib tread design.

Also note that there is a 45 day road test on all Cooper tires. Price points can very, so look for those deals from Discount Tire and Sears Tire Center
