What does the T or H mean on tires?

What does the T or H mean on tires?

The “T” or “H” on tires pertain to their speed ratings. A T-rated tire can withstand top speeds of up to 118 mph (190 km/h), while an H-rated tire can support up to 130 mph (210 km/h).

What does the P and R mean on tires?

P identifies your tire as a Passenger Tire. The P stands for PMetric. 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.

What do the codes on a tire mean?

The two-digit number that usually follows the tire’s section width tells us the aspect ratio, or tire profile measurement. A lower aspect ratio means a lower-profile tire with a shorter sidewall, while a tire with a higher aspect ratio will have a taller sidewall and look more like a donut.

Are H-rated tires good?

Sports cars may get better handling with a ZR tire. H-Rated Tires: This is a perfect, average tire for most sedans and commuter vehicles. It might not seem to fit in our chart, but the tire speed rating “H” is rated for up to 130 mph. T-Rated Tires: This tire is often recommended for family sedans and vans.

Can I use H-rated tires instead of V?

The rating is the speed the tire has been tested to for continuous safe driving. The English equivalent speed for H-rated tires is 130 mph and V-rated tires are good for up to 149 mph.

What does r19 mean on a tire?

Diagonal. 19. The tire size was designed to fit rims or wheels that are 19 inches in diameter.

Can I use ZR tires instead of R?

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. There is therefore no difference between a ZR or an R tyre with the same speed index.

How do I read tire codes?

Remember that the last four digits of the code are the date the tire was manufactured. You can check the first two digits of the DOT code to know the week of the manufacturing. The last two digits will reveal the manufacturing year. For instance, when it was written in 0203, the manufacturing year was 2003.

What does XL BSW mean on tires?

Extra Load Capacity
B, BLK, BW, BSW = Blackwall or Black Sidewall. W, WW, WSE = Whitewall or White Sidewall. XNW = Extra Narrow White Width. XL = Extra Load Capacity.

Which tire is wider a 65 or 70?

The series number in a tire-numbering system refers to the aspect ratio of the tire’s sidewall height to its width. A series 65 tire’s height is 65 percent of its width, a series 70 tire’s height is 70 percent of its width and so on. These differences in height affect both performance and safety issues while driving.

How much taller is a 65 tire than a 60?

The 65% aspect ratio (as in 235/65/17), compared to 60%, adds almost 12 mm (1/2″) to the radius of the tire (0.65-0.60)*(235mm)=11.75mm.
