Consumer Reports took a look at the CS5 Ultra Touring and CS5 Grand Touring tires from Cooper Tires when they did their annual tire review. The CS5 tires are both all-season radials that had identical performance test results in recent Consumer Reports testing. Traction News compares the two tires side by side and gets some insight from an industry insider.

Industry insider says they’re basically the same tire

An industry insider said that the quite similar scores these tires received from Consumer Reports and their very similar appearances help make them extremely similar in many ways. If you look at these tires, you’ll see that their tread patterns and the sidewalls look very similar.

He said the major difference between the two models is the Ultra has advanced construction that allows for the high speed ratings, like tighter wound plies, although the construction and basic design of the two tires are almost identical. The main reason for both an Ultra and a Grand is to make it possible to be OEM fitment for a wider range of vehicles.

Cooper’s CS5 Grand Touring is a “T”-rated all-season radial that can be found on minivans and passenger cars. They may also be found on light trucks.

The CS5 Ultra Touring is an all-performance all-season radial with “H,” “W”, and “V” speed ratings, according to both Cooper and Consumer Reports.

Uniform Quality Grading

Both the Grand Touring and the Ultra Touring were given traction and heat resistance grades of “A” in Uniform Tire Quality Grading testing. The Grand Touring received a treadwear rating of 780 in this testing. Those Ultra Touring that are “H” and “V” rated were given treadwear scores of 640, while “W” CS5s were bumped down to 500 due to the softer compounds that allow for the higher speeds.

Consumer Reports test results

Consumer Reports said both tires were rated “Very Good” in dry braking, hydroplaning, ride comfort and noise. Both also achieved scores of “Good” in wet braking and a score of “Poor” in ice braking. The grade of “Very Good” was given to the Grand Touring for snow traction and rolling resistance while the Ultra received a ”Good” for those categories.
