Top #1 Summer Tires: Michelin Pilot Sport 4S – 235/40r18
The 235/40r18 Michelin Pilot Sport 4S is Michelin’s Max Performance Summer tire, created in collaboration with some of the world’s most demanding car manufacturers, including Audi, BMW, Mercedes-Benz,
and Porsche, to take use of important technology developed during the 24 Hours of Le Mans competition.
It was created for serious drivers who want to get the most out of their sports cars, sports sedans, and powerful luxury automobiles. The Pilot Sport 4S thrives in warm dry and wet situations, thus it is not intended to be serviced, stored, or driven in near- or below-freezing weather, through snow, or on ice.
The Pilot Sport 4S has an asymmetric tread pattern with side-by-side compounds derived from the 24 Hours of Le Mans. The low-void outer shoulder has a new dry-focused hybrid tread rubber for better dry handling and braking than the previous generation tire, while the center ribs and inboard shoulder have a silica-infused wet compound for better wet braking performance.
During active use, the computer-modeled Variable Contact Patch 3.0 improves pressure distribution over the contact patch through turns, eliminating hot spots and increasing tire life.
Twin steel belts are reinforced by a spirally coiled hybrid reinforcement on the inside of the Pilot Sport 4S. Above the steel belts, this hybrid Aramid and nylon belt provides a lightweight, high-strength reinforcement to improve high-speed handling, wear, and longevity.
Michelin engineers were able to manage tension and strength by fine-tuning the application of the cord filament, and a single-ply, polyester cord casing balances trade-offs between ride quality and responsive handling.
Top #2 Summer Tires: Bridgestone Potenza Sport – 235/40r18
The 235/40r18 Bridgestone Potenza Sport, like all Max Performance Summer tires, is not designed to be maintained, stored, or driven in temperatures near or below freezing, through snow, or on ice.
Large, uninterrupted circumferential ribs for better longitudinal grip and broad, outboard shoulder blocks for increased cornering traction and lateral stability are used in the Potenza Sport.
The next-generation tread compound adds strength and stiffens the block, allowing for more responsive steering and high-speed performance.
Furthermore, the improved compound emphasizes improved wet traction and stability for capable wet performance. The pattern geometry was designed to guarantee level contact patch pressure while also encouraging water evacuation for even wear and hydroplaning resistance. For a smooth ride and minimal road noise, tuned tread block sequencing and lateral notches aid to reduce tread harmonics.
A single polyester casing is linked to twin steel belts, which are reinforced by a tough aramid-nylon cap ply on the inside of the Potenza Sport.
Top #3 Summer Tires: Continental ExtremeContact Sport – 235/40r18
Continental’s unique +Silane technology is combined with a superior summer
tread compound and a 5 or 6-rib asymmetric tread pattern for improved grip and handling on both dry and wet road surfaces.
Larger outside tread blocks and a continuous center rib, along with Continental’s proprietary SportPlus Technology, give this tire a faster steering response and feel while still providing the cornering grip and stability you’d expect from a UHP summer tire. In this regard, it ranks among the best tires in its class.
Increased grip on wet pavement is provided by the use of the +Silane compound and an improved footprint with broad circumferential grooves. The grooves make you feel more confident behind the wheel by limiting the likelihood of hydroplaning at higher speeds. On wet roads, we believe the 235/40r18 Continental ExtremeContact Sport is the company’s best tire to date.
Two high-tensile steel belts with a spirally wrapped polyamide top and two-ply sidewalls add strength and durability over the speed range inside the tire. Quickview Performance Indicators, similar to those seen on Continental’s DWS06 and DW models, have also been added.
These indications show you how the tire is wearing and whether it has enough tread depth for dry or rainy road conditions at a glance.

This tire is made with a special summer mix that includes micro silica and high-grip resin. Because the Ecsta PS31’s tread is directional, you can only spin the tires from front to back.
The Kumho Ecsta PS31 is a high-performance summer tire for sedans and sports coupes.
Top #5 Summer Tires: Falken Azenis FK510 – 235/40r18
Falken’s Ultra High Performance Summer tire, the 235/40r18 Falken Azenis FK510,
was designed for drivers of sports cars, sporty coupes, performance sedans, and current muscle cars that desire dry and wet traction and handling in a streamlined package.
Because the Azenis FK510 is designed to provide driver confidence in hot weather, it, like all Ultra High Performance Summer tires, should not be maintained, stored, or driven in temperatures near or below freezing, through snow, or on ice.
The 4D Nano Design tread compound on the Azenis FK510 is sculpted into an asymmetric, Adaptive Constant Pressure (ACP) pattern. The large, outboard shoulder blocks provide the lateral grip required during performance driving, while ACP increases pressure distribution throughout the contact patch for improved directional stability and shorter stopping distances.
The Switchback Siping aids to maximize rubber-to-road contact during wet cornering, and the tread composition was engineered at the molecular level to optimize adhesion in wet circumstances. To prevent hydroplaning, four large circumferential grooves allow water to pass through the contact patch.
Falken’s Tension Control Technology casing mold shape is used on the inside of the Azenis FK510 to give a flexible middle sidewall area for reduced impact harshness and a solid outside shoulder and bead area for handling capability. A hybrid Aramid and nylon undertread cap ply provides increased strength and high-speed stability to its two wide steel belts.
