Westlake Radial RP18 Tire Review

Searching for good quality, affordable tires can be a tedious process. The replacement tire market is oversaturated with different tire brands and models – some of which are not the best to say the least. This can easily create confusion and cause more problems than necessary.

Therefore, when we need new tires, we tend to either neglect the process or to just purchase the cheapest set available at that exact moment. Both of these situations are not the greatest option– driving on worn-out tires is dangerous, while cheap tires are usually not good quality.

So, what’s the best option?

The important thing is to find good tires at budget-friendly prices. This is where the Westlake Radial RP18 comes into play. This model ensures excellent all season traction at exceptional prices.

Experience the Westlake RP18 Radial

The Westlake Radial RP18 is a touring, all season tire. This manages to upgrade the all season traction and its controllability, while also boosting the comfort levels and the length of the service life.

All weather traction is ensured with the Westlake Radial RP18. It combines the all season compound and the detailed symmetric tread design in order to upgrade the tire’s surface grip. It allows the tire to boost the dry, wet, and winter weather performance. The high-density siping pattern and the notch placement enhance the tire’s road grip with additional biting edges. The stronger compound elements allow the tire to improve the rubber flexibility throughout the year, optimizing the summer and winter weather traction.

The tire is also able to avoid one of the most dangerous road hazards – hydroplaning. Its ideal tread design features four circumferential grooves, which channel water and slush from below the footprint, preventing water from blocking the surface contact. As a result, the tire effectively avoids hydroplaning, further upgrading the wet weather driving safety levels.

The ribbed tread design’s surface contact and the lower tire profile work together to improve the controllability. The Westlake Radial RP18’s tread with the vertical sipe placement ensures the surface contact at all times, which significantly upgrades the driving stability. On the other hand, the optimized tire profile allows the tire to greatly enhance the steering response time and accuracy to the driver’s instructions. Additionally, the detailed shoulder pattern allows the tire to boost the maneuvering capability. This enables the tire to greatly upgrade the cornering ability with the use of extra biting edges.

The Westlake Radial RP18 also guaranteed a longer usability. Westlake offers a 45,000 mile treadwear warranty with this model. This lengthened tread life is ensured with the non-directional tread design and the stronger rubber materials of the compound. They promote a slow and even wear, which allows the tire’s better service life. This is achieved as the ribbed pattern evenly circulated the driving pressure across the tread area, while the compound actively avoids pressure build-up on certain tread areas.

High driving comfort levels are optimized with the tread design. The tread features a variable pitch pattern which helps to lower the road noise generated while the tires are in motion. The tread manages to negate the sound waves created while the tires are in motion, promoting a quiet driving experience whenever the Westlake Radial RP18s are used on a vehicle.
