The internal construction of the tire consists of a high-turnup, single ply polyester casing, with two steel belts that serve as support. Cooper rounds-up the all-season moniker with full-depth 3D Micro-Gauge siping on the entire tread depth that creates biting edges for better grip and traction in low-friction surfaces, such as light snow. Wet traction is aided by ribs and inboard shoulders with high sipe density, lateral grooves, and more open space. Then, for better handling, Cooper incorporated outboard shoulder blocks with larger tread blocks and less void area. The tread is asymmetric, which means that the owner can rotate the tires from side to side to combat uneven wear. In order to achieve all those attributes, the Cooper CS5 Grand Touring is made of Coupled Silica compound. In this detailed comparison, you can see how they measure in several different categories, including dry, wet, and snow traction and performance, and also in the durability and comfort departments.īut first, let’s have a deep look in both products and see what are the differences according to Cooper Tire. Instead of making a standalone Cooper CS5 Ultra Touring review, or Cooper CS5 Grand Touring review, due to their similarities, I decided to compare them in one article. Both tires serve similar purposes, but they are still aimed at slightly different buyers. And one of the most popular choices in this category is the Cooper CS5 Grand Touring and Cooper CS5 Ultra Touring. These qualities make touring (and in extension Grand Touring and Ultra Touring) tires the best choice for sedans and compact cars. There are other traits that touring tires have that suit the casual driver, such as very low noise on the highway and comfortable ride over bumpy surfaces. Oh, and on top of that, they are less expensive. They are also much more durable than summer tires, with double the treadlife when compared to summer tires. Available in several different configurations, these tires are almost always of the all-season variety, which means that they work in a wider range of temperature conditions. High-performance tires are much safer than any other alternative in dry conditions, and some of them in wet conditions, but they completely fall apart when the temperature goes down. Most of the vehicle owners around the world want tires that will be safe and last for long periods of time. They've maintained their balance (with very little weight) I'd definitely recommend and buy again.High-performance summer tires may be great if you want the highest possible velocities in the corners, but for most people handling prowess is not the first thing they look for in a tire. They run very cool I typically cruise at 85 mph for more than an hour straight in 95 degree Fahrenheit, and I can immediately leave my hand on the drive tires for more than 3 seconds (the old 'thumb test' for transistors :). On anything other than well worn cement, there is no whine very quiet on asphalt. They are the quietest tire I've ever had on this car, but the del Sol is a noisy car independent of the tire used so one would hear any tire. They show very little wear at 15K miles the past high performance tires I've used would been more than 1/2 way gone at 15K. In the wet they are fantastic, 85 mph in Texas downpour without a hint of hydroplaning, very impressive in my opinion. But dry grip is still very good and they're very progressive at the limit with excellent feedback without being harsh. I've always used lower end high performance tires in the past, and the Cooper CS4 doesn't have the grip of those tires in the dry. I can't comment on snow living in Texas, but everything else they handle admirably. Put these on a Honda del Sol because I needed a mileage tire and 15K miles since, they are working fine.
