Tires have made remarkable technological advances in recent years, as evidenced by various reports from research and development laboratories.
The “doughnut” sector attracts a wide range of professional and lay motoring society, especially as tires guarantee the vehicle’s contact with the road. Their properties thus contribute significantly to the safety of the operation and driving characteristics of the vehicle.
Runflat tires have become a contribution to the comfort and safety of operation enabling you to continue driving under certain circumstances in case of a flat tire. Later, tire manufacturers have come up with self-sealing tires such as Continental’s ContiSeal tire that will immediately seal the hole up to a diameter of 5 mm.
Another, rather wide area is the development of optimal sidewall and profile mixtures and designs so that the tires can do their best. More and more popular electric cars also bring new requirements for tires, and the use of ecological technologies.
Let’s mention one of the revolutionary tire design solutions – the Michelin Visionary Tire concept, in which the Michelin Uptis tire integrates the disc and the tire into one unit. The tread will change with the fully automatic Michelin system thanks to the 3D printer. Goodyear reCharge is another revolutionary concept of self-regenerating tires that can be adapted and changed according to individual needs. The renewable and biodegradable tread compound can be recharged by segments. The tires adapt exactly to the conditions of use.
Ready for Summer
Let’s stay in the present and ask the question: how can we be familiar with the range of tires? Current results of tests conducted by reputable companies or professional journals can be a good guide. Since we are using summer tires, we will look at the results of the ADAC test of 185/65 R15 summer tires for small vehicles, as well as the tested products with dimensions of 215/60 R16, suitable for medium-class vehicles.
16 current models were included in the 185/65 R15 tire test, none of which showed serious deficiencies in the evaluation of dry, wet, noise, fuel consumption, and wear. Six models received a particularly recommended rating (good) and another ten are recommended (satisfactory). Top six places – Goodyear EfficientGrip Performance 2, Bridgestone Turanza T005, Michelin Primacy 4, Pirelli Cinturato P1 Verde, Dunlop Sport BlueResponse, and Giti GitiSynergy H2.
In the 215/60 R16 category, 18 tires participated in the test and the first five received a particularly recommended rating (good) – the product Continental PremiumContact 6 convinced the most, Michelin Primacy 4, Bridgestone Turanza T005, Dunlop Sport Bluresponse, and Toyo Proxes Comfort finished in other places. There were no shortcomings in any of the assessment criteria for these tires and they scored because of their balanced characteristics. Another “twelve participants” received the recommended rating (satisfactory) and one tire had the recommended rating only conditionally (sufficient).
