What is the best tyres for 225 40R18?
ANWB’s 225/40 R18Y tyre buying tips The most durable tyre in the test is the Michelin. Behind it come the Continental, the Goodyear and the Falken. The tyres with the best wear resistance (after discounting the Double Coin DC-100) are the Michelin, followed by the Goodyear and the Bridgestone. As one might expect, Michelin demonstrated the longest tread life, surpassing Goodyear and Continental by 15%, Hankook by 24%, and Bridgestone and Yokohama by a significant 33%.
What is the best tyre pressure for 225 40 R18?
The recommended tyre pressure for 225/40 R18 tyres can vary slightly based on the manufacturer and vehicle. However, a general guideline is to maintain the pressure within the range of 32 to 35 PSI (pounds per square inch). Running your tires at the correct pressure is important because it keeps you safe, cuts down your gas bill, and makes your tires last longer. Each vehicle has its own specifications for tire pressure, but most fall between 28 and 36 PSI (pounds per square inch).
What size tyre is 225 40ZR18?
The tyre size 225/40 R18 means the tread width is 225 mm, the sidewall height is 40 % of that width, and the tyre fits an 18-inch wheel. R – The ‘R’ in this construction indicates radial tyre construction, almost every new tyre built today is a radial tyre. This indicates the wheel diameter which is measured in inches.Not quite the same diameter. The “40” means the sidewall is 40% of the first number. So a 235/40 will have a 94mm sidewall while the 225/40 has a 90mm sidewall.The tyre size 225/40 R18 means the tread width is 225 mm, the sidewall height is 40 % of that width, and the tyre fits an 18-inch wheel.
What does z mean in tire sizes?
SPEED RATING Z While it nearly always means a high performance tire for high-performing sports cars, “Z” may actually appear in the middle of a tire’s size information. When it does, it represents either a maximum speed of more than 149 mph (240 kph) or 186 mph (300 kph). ZR-Rated Tires: The ZR rating (or Z rating) indicates anything above the V rating (168 mph), so it includes both the Y and W speed rating. Sports cars will often get the best handling with these tires.Are ZR tires better than R? ZR tires offer superior high-speed performance and handling but are less durable and less comfortable. They are better for high-performance drives but might not be better for everyday use.While a Z-speed rating still often appears in the tire size designation of these tires, such as 225/50ZR16 91W, the Z in the size signifies a maximum speed capability in excess of 149 mph, 240 km/h; the W in the service description indicates the tire’s 168 mph, 270 km/h maximum speed. Tire Size.When saving the tread life of the tire is more ideal, the 225/40R18 will be longer than the 225/40ZR18 under normal road use. As for the speeding capability, the ZR-rated version has an optimized performance/durability ratio suited to high-speed operation.When saving the tread life of the tire is more ideal, the 225/40R18 will be longer than the 225/40ZR18 under normal road use.

Does the R in tire size matter?
R indicates the construction used within the tires casing. R stands for radial construction. B means belted bias and D stands for diagonal bias construction. The last dimension listed in the size is the diameter of the wheel rim, which is most often measured in inches. The Z in ZR corresponds to an old label used by manufacturers to indicate that the speed index is higher than V, i. Thus, a ZR tyre has a speed index of V, W, or Y. R indicates that the structure is RADIAL. So, VR indicates that the tyre has a RADIAL structure and a speed index equal to V.Letters ranging from A to Z represent the speed rating. Each letter denotes the maximum speed a tyre can sustain under its recommended load capacity. In our example, “H” is equivalent to a maximum speed of 130 mph (209 kph).ZR means the tire can handle speeds over 150mph. R18 is the rim diameter the tire fits on. W is the load and speed rating. XL means the tire is “extra load”.
What does R18 mean on tyres?
R – The ‘R’ in this construction indicates radial tyre construction, almost every new tyre built today is a radial tyre. This indicates the wheel diameter which is measured in inches. The letter R means the tyre is a radial construction. Almost all new car tyres are radials.This new European tyre label applies to passenger car tyres (C1), light truck tyres (C2) and heavy truck tyres (C3).
Is zr better than r tires?
Are ZR tires better than R? ZR tires offer superior high-speed performance and handling but are less durable and less comfortable. They are better for high-performance drives but might not be better for everyday use. ZR means the tyre has been designed to be driven at speeds of 150mph and above.
