Friends say my car tires a bit narrow, I suggest that a wide point, do not know okay?
Can not replace the different tires, the parameters 195 / 65r15 as an example, meaning as follows: 195: tire width is 195 mm; 65: called the tire flat rate, meaning: sidewall height (fetal wall) and the ratio of the width of the tire is 65%; R: wire radial tire, 15: the diameter of the hub is 15 inches. Tire is one of the most important components of the car, its role is: to support the full weight of the vehicle, to withstand the load of the car; transfer traction and braking torque to ensure that the wheel and the road adhesion; reduce and absorb the car Driving vibration and impact, to prevent the car parts are subject to severe vibration and early damage to adapt to the high-speed performance of vehicles and reduce the noise when driving to ensure the safety of driving, handling stability, comfort and energy saving economy.
Can be replaced, but need to be calculated, can not be replaced with the wide tires, as well as the replacement of a wide tire will increase fuel consumption, it is recommended not to be replaced. Feasibility and implementation are two concepts that need to be considered for cost and practicality.
The tire size must be the same as the original car assembly tires specifications, if necessary to change the tire specifications must go to a professional modified store for tire upgrades, or consult the car manufacturer.
Tire specifications are often used in a set of numbers, the previous number represents the width of the tire section, and the latter represents the rim diameter in inches. For example, 165/70R14 represents a 165 mm wide tire, a flatness of 70, and a rim diameter of 14 inches. The middle of the letter or symbol has a special meaning: "X" that high-pressure tire; "R", "Z" said radial tire; "a" that low-pressure tire. Q: 160 km / h; R: 170 km / h; S: 180 km / h; T: 190 km / h; H: 210 km / h; V: 240 km / h; W: 270 km / h; Y: 300 km / h; ZR speed is higher than 240km / h.
