What does 120Q mean on a tire?
The next number is the diameter code, in inches, of the rim onto which the tire can be mounted. For example, a tire with the 33X12. 50R17LT 120Q would fit a rim with a 17-inch diameter.
What is a good load index?
The higher the tire’s load index number, the greater its load carrying capacity. Choosing a tire with a lower load index than the original equipment specifications means that the tire will not carry the load capacity of the original. Most passenger-car tire load indexes range from 75 to 100, but some are higher.
What is a load index?
The tire load index lets you know the load carrying capacity of a tire. In other words, it’s the amount of weight your tire can support safely. For example, if a tire has a load index of 92, it can support 1,389 pounds at maximum air pressure.
What does 125s mean on a tire?
Load and Speed Ratings- 125/122 seen in the above tire sidewall refers to the load rating of the tire. 125 denotes that each tire can carry 3638 pounds at the maximum inflation pressure.
What does LT stand for on tires?
Light Truck
If a tire size reads, LT235/75R15 104/101S, the LT indicates that this tire is meant for Light Truck use. These tires are made for light-duty and heavy-duty pickup trucks (typically ½ ton, ¾ ton, or 1-ton load capacity), SUVs and vans.
Do LT tires ride rough?
LT tires are built for heavy vehicles, so their stiffness can give your vehicle a harsh ride, and since they require higher tire pressure, they can throw off your vehicle’s TPMS (Tire Pressure Monitoring System, a safety feature that alerts you to improper pressure in your tires).
Is a higher load rating better?
Usually considered in combination with a tyre’s speed index, the rule of thumb is that tyres with a higher load index number are capable of carrying a heavier load capacity than those with a lower number. This can be compounded even further where the tyre pressure is incorrect.
What load index is a 10 ply tire?
Light Truck Tires
| LT-Metric, LT-Flotation and LT-Numeric Light Truck Tires | ||
|---|---|---|
| Load Range | Ply Rating | Maximum Load Pressure ≤ 295mm / 11.5″ wide |
| D | 8 | 65 psi (450 kPa)*** |
| E | 10 | 80 psi (550 kPa)*** |
| F | 12 | 95 psi (650 kPa)*** |
What does Zr mean on tires?
Tire Speed Rating Chart For tires with a maximum speed capability higher than 240 km/h (149 mph), a “ZR” may appear in the size designation. Tires with a maximum speed capability higher than 300 km/h (186 mph), require a “ZR” in the size designation.
What does BSW mean on tires?
Blackwall
B, BLK, BW, BSW = Blackwall or Black Sidewall. W, WW, WSE = Whitewall or White Sidewall. XNW = Extra Narrow White Width.
Is an LT tire 10 ply?
The cords in a LT tire are a larger gauge than P-metric tires so the tire can carry heavier loads. LT tires are usually 8-ply (Load Range D) or 10-ply (Load Range E). Passenger Tires usually have a 4-ply or 6-ply equivalent sidewall.
What is the difference between load range and load index?
Load index is a more precise method of measurement than load range which focuses mostly on construction. The load index number indicates a tire’s carrying capacity when inflated to maximum load sustaining pressure. It further explains the tire load range measurement by adding more specifics to the rating.
What does “e” load range mean?
For example, an “E” load range indicates that a tire is equivalent to a 10-ply construction tire. In realitly, this tire is not built with 10 plies, but rather one or two plies of equivalent strength.
What is the load index of a tire?
The load index refers to the load-carrying capacity of a tire, or how much weight a tire can support. For example, if a tire has a load index of 89, it can support 1,279 pounds (from below chart) at maximum air pressure.
What are the load-carrying capacity index ratings for the US?
Load- Carrying Capacity Index Ratings 44 353 94 1477 144 45 364 95 1521 145 46 375 96 1565 146 47 386 97 1609 147
