What does the 91H mean on a tire?
A: Hello, the number stands for the load index (91 means tires tested up to 1358lbs), and the speed index (H rated tires tested up to 130mph, T tested up to 118mph). For instance, the index “91V” indicates a maximum speed of 240km/h (based on a table), and the letter “V” is an alphabetical index, by which A indicates the lowest and Y the highest speed class.A: Hello, the number stands for the load index (91 means tires tested up to 1358lbs), and the speed index (H rated tires tested up to 130mph, T tested up to 118mph).According to the chart below, tires with this marking are good for speeds up to 149 mph (240 km/h).
What’s the difference between 91H and 91V?
These two speed ratings are most frequently made for performance tires, but which one is better? The main difference between 91v vs 91h tires is definitely speed. H speed-rated tires have a capability of 130 mph, while the v has a maximum speed of 149 mph. In the battle of t and h ratings, h is generally perceived as being better. H-rated tyres are effectively able to cope with 12mph faster speeds, can cope with greater friction at all speeds, and have significantly more capacity for heat resistance.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. It’s rated for up to 118 mph.A vehicle originally delivered with tires rated H or V will offer not perform as well with S-rated tires installed (see the chart below). Steering, braking, handling and stability can all be affected, because the sidewalls of an S-rated tire are not as stiff as those of an H- or a V-rated tire.The choice between H and T tires is actually based on speed ratings: while H-rated tires allow a top speed of 130 mph, delivering superior handling and heat resistance. T-rated tires max out at 118 mph and thus favor durability and comfort for everyday use.Absolutely, NO. H-rated tires only allow you to rev up within a maximum range of 130 mph. In comparison, V-rated ones extend the performance of tires up to 149 mph. The distinction comes from the theoretical aspect of speed and the driving experience.
What is the difference between 205 55r16 91H and 205 55r16 91V?
H-rated tires are rated for a maximum speed of 130 mph. The V rating is the next rating faster, and V-rated tires are good to 149 mph. H Rating: Can provide extended tread life and durability with proper maintenance. V Rating: Typically has a shorter tread life due to the higher performance and grip characteristics.
What is the tire pressure for 205 55 R16 91H?
However, as a general guideline, the recommended tyre pressure for 205/55 R16 tyres typically falls within the range of 30 to 35 PSI (pounds per square inch) for passenger vehicles. Tire pressure increases when the tires are used, and for this reason, following the vehicle and tire brands’ recommendation is crucial. Typically, if the recommended pressure levels are 35, then the tires should not use more than 40 psi. More than that will result in the before mentioned problems.While you should always stay within this range, you should also never be below 20 PSI, or over 50 PSI, or you risk serious tire damage (more so than with standard overinflated or underinflated tires to a lesser degree). Your car may have different ideal tire pressures for the front and rear axles.However, as a general guideline, the recommended tyre pressure for 205/55 R16 tyres typically falls within the range of 30 to 35 PSI (pounds per square inch) for passenger vehicles.
What does 205 55 R16 91H mean?
For example, if you read 205/55/R16 91H, it means: The width of the tire (in millimeters) The type of construction (R for radial, D for diagonal and B for belted) The wheel diamater (in inches) The speed rating. Third number is the wheel size in inches. So a 205/55R16 is a tire that is 205mm wide, 112. A 205/60R16 is 205mm wide, 123mm high, on a 16 inch wheel. Both of there tires can fit on a 16 inch wheel.
What does 205 stand for in P205 55 R16 91H?
Example P205/55R16 91W. P identifies your tire as a Passenger Tire. The P stands for PMetric. If your tire size starts with LT rather than a P than it identifies the tire as a light truck tire. Tires of the 205/55R16 size fit 16-inch wheels that are between 6. They comprise both tires for road use as well as winter tires. This size is common for winter tires because they are relatively tall and narrow, allowing the tire to more easily cut through snow to reach the pavement beneath.
What does 91H mean on tyres?
The load capacity index and the total weight of your vehicle If a tyre has a load index of 91h, for example, this means that the load on this tyre must not exceed 615 kg. The letter h, on the other hand, is the speed rating, which is 210 km/h. The difference is the speed rating or what the tires are tested up to for speed. A T speed rated tire is tested up to 118mph while H is tested up to 130mph. A difference in this rating should not cause you issue unless you are hitting max speeds or if your vehicle is all wheel drive.
