11 Things To Know About Boat Trailer Tires Load Range. Every tire has a load range, and trailer tires are no different. Marked on the sidewall, the load range runs from the lightest weight the tire can carry (Load Range B) to the heaviest (Load Range E). Load range is a measure of an individual tire's maximum capacity to carry a boat and trailer.

- So even though the OE tire we used for an example is E rated with a maximum pressure of 80 PSI, the plus size D rated tire carries more weight at a lower pressure. In other words, LOAD RANGE E doesn't always mean the tire can carry more weight at maximum pressure when compared to LOAD RANGE D at maximum pressure.

- Since the combined load rating (5908 pounds) for the four tires is greater than the 4597-pound GVWR, you’re good to go. If you know the tire load rating for your vehicle, you can use our handy load index chart to check out the load carrying capacity of your tires. When you shop for tires and give us your vehicle’s make/model/style information, we show you only the tires that have the proper load rating for that vehicle.

- Please note that there is no correlation between a tire’s Load Range (or ply rating) and its inflation pressure at which it achieves its maximum load. In reality, tires of the same Load Index may require dramatically different pressures to achieve their published load ratings.

Tire Load Index Chart The load index is identified as a part of the tire size designation or the tire's service description, together with the speed index (e.g. Size designation: 205/60R15 91V - 91V in service description means this tyre can carry maximum 615 kg/1356 lb while going up to the maximum speed of 240kmh/150mph).

- Any replacement tire on any light truck must be of a size and load range that will offer equal or higher load carrying capacity compared to the original equipment tire on the vehicle. Note that size for size, LT tires require higher air pressures to carry equivalent loads of P-Metric tires.

Load Range E 10 Ply Tires for Heavy Duty Use …Many full-sized pickups and cargo vans require load range E tires. If your pickup truck or van is a 2500 or 3500 (commonly called 3/4 ton or 1 ton), your vehicle falls into this category. Load range E tires are the equivalent of the older 10 ply rated tires and are often still referred to as such,….

Breaking the Code: Tire Load Index Chart Most standard light truck and passenger tires have tire load index ratings between 70 and 110, but drivers should consider a higher tire load index rating if they consistently haul heavy equipment. Below is a load index chart that converts common ratings into their proper load capacities.

- Tire Tech. Load Range / Ply Rating Identification. The load range/ply rating branded on a tire's sidewall identifies how much load the tire is designed to carry at its industry specified pressure.

How to Determine Tire Load Ratings C, D, or E tires are capable of greater loads. Most load range C, D, and E tires are intended for light-truck applications. The load-carrying capacity of Pmetric tires is rated as either Standard or Extra Load. Standard Load tires are limited by the load that can be supported with a maximum inflation pressure of 35 psi.

Tire Specs Explained: Maximum Load Maximum Load. A tire's maximum load is the most weight the tire is designed to carry. Since a tire's load carrying capacity is related to the tire's size and how much inflation pressure is actually used, maximum loads are rated with the tire inflated to an industry assigned inflation pressure.

Understanding Tire Load Ratings Photo 3/6 | Sidewall specs indicate a maximum load of 3,000 pounds at 50 psi, 105 pounds under OE rear weight-carrying spec. The tire’s Service Description code is to the left of the Load Range: Load Index (199 = 2,998 pounds) and Speed Rating (Q = 99 mph).

Tire Specs Explained: Maximum Load Higher load ranges are used to identify tires that have a stronger internal construction, and therefore can hold more air pressure and carry more weight. Each load range has a assigned air pressure identified in pounds per square inch (psi) at which the tire's maximum load is rated.

Load Range C LT-Metric, LT-Flotation and LT-Numeric tires are branded with their load range (Load Range E or LRE) or their ply rating (10 Ply Rated) on their sidewalls and list their appropriate load range letter in their descriptions as: 1  LT235/75R-16 E, 2  9.50R-16 D, 3  31x11.50R-15 C, or.  ST225/70R15 LRD.

PLY RATING Load Range indicates the maximum load recommended for the tire. This varies by tire size and inflation pressure: A bigger tire can hold more air and can be rated for a higher load. Also, a given tire size at a higher air pressure results in a higher-rated load.

Tire code In the example shown in the light-truck tire illustration, the tire has a load index of 114 if used as a single tire, and a load index of 111 if used in a dual pair. Tires without this designation are unsafe for dual usage.

Load Range, Ply - Speed Rating & Load Index Load Range and Ply Rating. Ply ratings and load ranges identify load and inflation limits of a given tire size when used in a specific type of service. 1  Ply ratings: An older method of rating load capacity. 2  Load ratings: The current method of rating a tire's load-carrying capacity.

- The tire sidewall indicates they have a load capacity of 1823 lbs at max inflation. I am thinking that given the weight in the trailer, I may be close to the limit on tire load. Questions: - I was thinking of going to a load range D tire in the same size.

Load Range / Ply Rating Identification Passenger Tires. Since most P-metric passenger tires are manufactured in the standard load range, they will have nothing branded on their sidewalls or may be branded standard load and identified by an SL in their descriptions, as in P235/75R-15 SL.

What Does a Load Range of SL on a Truck Tire Mean? If our P235/75R15 tires are used on a truck or SUV, the maximum load per tire is 2,028 times 91 percent or 1,845 pounds. The total weight for the vehicle should not exceed 7,380 pounds. The load capacity of an SL load range tire does not increase by inflating the tire to more than 35 psi.unction. Tires are given a maximum load rating based on the tire's size, construction and inflation pressure. P-metric sized tires--tires with sizes starting with a P such as P235/75R15--are given a load range rating of either SL or XL.

- The letters SL on the sidewall of a truck tire indicate that the tire is a standard-load tire that holds a maximum load pressure of 35 pounds per square inch. This is the maximum load the tire carries, and manufacturers determine this capacity based on the size of the tire. Continue Reading.

Load Range, Ply - Speed Rating & Load Index I was concerned that it was a load range 'D' and not 'E'. The Yokohama and the Goodyear GSA both have a load capacity of 3525 @ 50 psi per tire. Since 50 PSI is the maximum amount of pressure you can put in the tire using the CTIS pump, for all practical purposes the tires are equal in the load they will carry.

Understanding Tire Load Ratings A tire’s load range letter is an attempt to equate radial tires’ carrying strength in old bias-ply terms. Air pressure is the functional indicator: Higher-load tires accept higher maximum pressures. Also, a single mono steel ply, or one-ply, is stronger than multiple cotton-cord plies from the early bias-ply days.

Load Range / Ply Rating Identification Today's load range/ply ratings do not count the actual number of body ply layers used to make up the tire's internal structure, but indicate an equivalent strength compared to early bias ply tires.T-metric sized special trailer service tires will be branded with their load range (load range D or LRD) on their sidewalls and list their appropriate load range letter in their descriptions as ST205/75R15 LRD.
