What does zr17 mean on a tire?

On a sports bike tyre these letters are usually “ZR”. The “Z” indicates the speed rating of the tyre, which in this case means it is rated above 240kph/149mph. The “R” denotes that the tyre is of radial type construction.

What is difference between R and ZR tires?

The Z in ZR corresponds to an old label used by manufacturers to indicate that the speed index is higher than V, i.e. 150 mph. Thus, a ZR tyre has a speed index of V, W, or Y. R indicates that the structure is RADIAL. There is therefore no difference between a ZR or an R tyre with the same speed index.

What does R mean in tires?

radial construction
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. Each letter coincides to the maximum speed a tire can sustain under its recommended load capacity.

What are Z rated tires?

A “Z” rating can mean different things. 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).

What’s the difference between r17 and zr17?

can a zr17 tire fit on an r17 rim? ZR basically means the tire is adapted for speeds above 149mph. ZR tires includes the speed ratings V(149mph), W(168mph) and Y(186mph). The R stands for radial.

What does the XL mean on tires?

XL tyres have been especially developed for use with heavy loads. Generally speaking, the tyre name XL is used for heavy duty tyres. However, the labelling varies between tyre manufacturers. Sometimes you might have XL tyres that are also labelled “reinforced” (RF or RFD), or models labelled EL (Extra Load).

Do wider tires ride smoother?

As a general rule, bigger wheels result in a rougher ride. Switching to a smaller wheel and a thicker tire can give you a smoother ride without any major modifications to your car. If you’re looking for a bigger wheel which can provide better handling, you can go up to an 18-in wheel.

What does Q mean on a tire?

Tires with a Q speed rating can safely sustain speeds of up to 99 miles per hour. The tire may be able to reach higher speeds, but going faster than 99 mph for any length of time is not safe. The tire is not designed to handle the stresses.

What does H and T mean on tires?

The codes on the sides of tires are unfamiliar to most car and truck owners, but knowing what the codes mean is important to choosing the proper tires. The H/T on tires stands for highway/terrain.
