What is the tire size of the Jeep Wrangler?

[Olive]

The Jeep Wrangler has three tire size models: 255/70R18 for the 2022 Wrangler 2.0T High Altitude 4-Door, 245/75R17 for the 2021 Wrangler 2.0T Sahara 2-Door, and 255/75R17 for the 2021 Wrangler 2.0T Rubicon 4-Door. In 255/70R18, the first number 255 represents the tire width of 255MM, 70 indicates the aspect ratio of the tire section is 70%, meaning the section height is 70% of the width, and 18 stands for the rim diameter of 18 inches. The letter R in the middle denotes a radial tire. In 245/75R17, the first number 245 represents the tire width of 245MM, 75 indicates the aspect ratio of the tire section is 75%, meaning the section height is 75% of the width, and 17 stands for the rim diameter of 17 inches.

Car tires are one of the essential components of a vehicle, directly contacting the road surface. Together with the car suspension, they cushion the impact during driving, ensuring good ride comfort and smoothness. They also ensure excellent adhesion between the wheels and the road, improve traction, braking, and off-road capability, and bear the vehicle's weight. Tire usage precautions: Regularly check tire pressure. Tire pressure significantly impacts tire lifespan; it should not be too high or too low. Inflate according to the vehicle's indicated tire pressure. In summer, try to keep the pressure slightly lower. In winter, ensure the tire pressure is slightly higher than in summer due to thermal expansion and contraction. Frequently inspect tire wear. Some vehicles may experience uneven tire wear, so regularly check tires, especially the inner side, for abnormal wear. Focus on whether the tread depth is consistent on both sides. Promptly remove small stones or debris from tire treads. Foreign objects in the tread can pose potential hazards, possibly flying out during driving. Therefore, keep tires clean. Storage method: Prolonged exposure to direct sunlight or rain can cause tires to lose luster, accelerate aging, and develop fine cracks. Avoid long-term outdoor storage. During storage, avoid direct sunlight, UV exposure, ozone, oil contamination, and high temperatures. Store in a cool, shaded place and deflate the tires. Move tires indoors during rain to prevent water ingress. Tires contaminated with oil or water are prone to damage or deformation. Store away from oil and water, avoid places that may cause damage or deformation, and keep away from generators or batteries. If storing dismounted tires for a long time, note that chemicals may seep out and stain the floor. Jeep Wrangler tires are from the Goodyear brand, and the spare tire is full-sized. Besides the model, tires also display the following common data: Tire cord material: Indicated by Pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tires. Speed rating: Indicates the maximum speed a tire can carry a specified load under defined conditions. Letters A to Z represent certified speed ratings from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h. Rim specification: Indicates the rim size compatible with the tire for practical use, e.g., standard rim 5.00F.
