Rubber punctures and cuts happen regularly. It is especially unpleasant when damage occurs far from settlements. A flat tire can lead to a long stop on the road. We have to raise the body on the jack and put the spare wheel. Especially for such situations, the RunFlat technology was developed, which allows you to resume movement on a punctured wheel.

There are several varieties of this technology, but the reinforced sidewall design has become widespread. In the event of a puncture, it can withstand the weight of the car, and you can drive on rubber without any negative consequences up to hundreds of kilometers. The only inconvenience will be the speed limit — no more than 80 km / h, so that the tire does not fly off the disk when the steering wheel is turned.

Bridgestone Blizzak RFT

One of the best winter tires with runflat sidewalls, provides stability on the road with rubber damage and pressure release. This model does not provide for the installation of spikes, has a universal asymmetric tread pattern that gives reliable grip on any surface. The great demand for reinforced tires is also due to a wide range of sizes — products with an inner diameter of R16 — R19 and a profile height of 45 -55 mm are on the market. A wide choice and on width — from 195 to 265 mm.

The rubber compound contains an RC-polymer modifier, which gives the tire stability during temperature fluctuations, which significantly improves performance. Throughout the depth of the tread there are small cavities, which, as they wear out, become new sipes. As a result, grip properties remain stable throughout the entire service life, regardless of tire wear.

Michelin Alpin 5

High-tech tire designed for operation in moderate winter conditions. The dimensional grid allows you to install tires on passenger cars and crossovers — RunFlat rubber is available with an inner radius of R16 — R18 and a profile height of 45 to 60 mm. One of the distinguishing features of this rubber is a reinforced sidewall, which the manufacturer calls a little differently — Zero Pressure. With its help, the possibility of loss of control during a sharp release of tire pressure is minimized, which at high speed in winter conditions is an indicator of a high level of safety.

At the same time, the tire received other advantages — the acceleration dynamics was improved, the braking distance became 5% shorter and the overall operational life increased. All this is a great merit of the Heliocompound Plus rubber compound preparation technology, which contains silicon compounds and sunflower oil. The characteristic V — shaped pattern with three-dimensional Stabiligrip lamellas (with respect to the axis of rotation of the wheels are applied at different angles) provides an amazing «grip» of rubber on any surface, including bare ice, snow and wet roads.

1 Nokian Tires Hakkapeliitta 7 SUV

Nokian Tires Hakkapeliitta 7 SUV

The tire of the Finnish concern, regardless of which factory it was produced in, can safely be considered the best winter tire in our rating. To achieve maximum safety, some prestigious car brands are equipped with these tires with RunFlat technology as standard. The reinforcement of the side part is implemented in the most popular sizes with R17 and R19. Nokian Tires in these tires uses special components that give the rubber a significant rigidity, which does not deform when the cylinder is depressurized, and can withstand the weight of a car with a full load. In this state, you can overcome 100 or more kilometers (in the absence of passengers in the car and an empty luggage compartment). Before repairing tires that were forced to operate without pressure, you should carefully examine the inner and outer surface of the tire for delamination of the sidewall reinforcements from the main carcass, and only then deal with its restoration. To comply with the rules for the safe operation of runflat tires, it is strongly recommended to replace the rubber after a run on a flat tire.

The best summer tires with runflat technology

5 Dunlop SP Sport Maxx TT

Dunlop SP Sport Maxx TT

The peculiarity of this high-speed runflat tire is that a braided Kevlar thread and a special rubber mixture containing nanoparticles of a substance whose strength is comparable to diamond are used to reinforce the sidewall. This provides good performance, and allows the flat tire to carry the weight of the car and continue to move. In addition, the high strength of the working surface prevents minor cuts and punctures, and the reinforced sidewall impact loads are not able to cause such damage as a conventional tire. RunFlat rubber is available in the most popular sizes for luxury cars — 195/55/R16 and R17 (profile height varies from 40 to 60 mm.)

4 Kumho Ecsta PS71

Kumho Ecsta PS71

The RunFlat tire from the popular South Korean brand is not only attractively priced. It has high performance and is recommended for anyone who is used to driving fast. Can be installed on vehicles with R16 – R19 rims (tire profile height from 40 to 55 mm.). The reinforced sidewall ensures the vehicle’s safe behavior in the event of a tire failure and further improves cornering handling by enhancing clutch performance.

The sporty tread pattern creates not only a reliable fit of the tire to the asphalt — it allows you to evacuate large volumes of water from the contact patch, preventing the occurrence of aquaplaning. Rubber compound based on styrene-butadiene rubber and polymer modifiers provides moderate wear during intensive use, excellent braking performance and better grip. In addition, despite the sporty character and the rigid runflat sidewall, the tire demonstrates low noise levels, which makes it one of the most sought-after high-speed summer tires in the category.

3 Yokohama Advan Sport ZPS

Yokohama Advan Sport ZPS

Advan Sport ZPS is great for lovers of speed. RunFlat sidewall reinforcement is available in models with R16 – R20 radius and profile heights of 50 and 55 mm. Runflat provides safety when depressurizing tires — this is of great importance at high speed (slow and measured driving characteristics of rubber do not allow).

A very soft tread with numerous technical features of the pattern is literally “pasted” into the roadbed and does not deviate from the set course either in high-speed turns or when driving along a straight path. The reaction to the steering wheel is instant and clear, no hint of roll, even when more than half of the tread is worn. The tire provides the efficiency of the braking system, its performance is especially impressive on vehicles with all-wheel drive. During the operation, only two drawbacks were identified — increased noise of a sports tire and rather intensive wear of the working surface.

2 Michelin Pilot Sport PS2

MICHELIN Pilot Sport PS2

This high performance tire is designed for powerful sports cars and premium cars. Available in sizes with an inner radius of R18 — R20 and a profile height of 25 to 40 mm. RunFlat reinforcement minimizes the impact of a sudden loss of tire pressure on handling. These tires are installed as factory equipment on the BMW 3 and the most powerful ever Chevrolet Corvette ZR1e. This is quite enough to understand what the Pilot Sport PS2 rubber is capable of.

Confident grip on dry and wet roads ensures reliable and efficient operation of the braking system and high acceleration dynamics. With a sharp start, the tire “bites” into the asphalt so tenaciously that there is practically no slippage. It reacts to the steering wheel without delay, sharply and reliably maneuvering at speed. Despite the rigid runflat sidewall, tire wear is quite intense, and directly depends on the nature of the ride. The noise level is on the borders of comfortable perception, but this is a reasonable price to pay for other advantages of the tire.

1 Pirelli Cinturato P7

Pirelli Cinturato P7

In the production of tires, a natural rubber compound is used, which makes the Pirelli Cinturato P7 one of the most environmentally friendly. Strengthening the sidewall using RunFlat technology provides reliable grip on the road — in case of a tire puncture and a sharp release of pressure, the stability of the car’s behavior is maintained. And if there can be emergency situations on a conventional tire when driving at speed, then with runflat rubber, the driver can notice a flat tire only thanks to the tire pressure monitoring system and reduce the speed to a level acceptable in such situations. Reinforced tires are represented by a wide size range with a landing radius of R16 — R19. Ultra-low models are available with a profile height of 35 — 40 mm.

Thanks to the “steel” side of the Pirelli Cinturato P7, it demonstrates phenomenal control accuracy, and cornering does not require slowing down (you can safely maneuver 15-20 km / h faster than on conventional rubber). The tread pattern and its high elastic properties provide excellent grip on dry and wet pavement, as well as predictable braking performance. Due to excessive rigidity, the noise level is above the threshold of comfortable perception, but this is more than compensated for by high driving characteristics.
