What does load range LRC mean?
Load ranges are equivalent to previous plies and are thus called “ply rated.” For example, a Load Range B (LRB) trailer tire is 4-ply rated, rather than 4 -ply; LRC is 6-ply rated, and so on.
What is the difference between LRB and LRC?
Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same size but it will not increase the capacity of the trailer.
What is LRC in trailer tire?
Expert Reply: Your ST205/75R15 trailer tire features a Load Range C which, according to the tires we have available in this size such as the Provider # TTWTRTM2057515C, gives it a maximum load of 1,820 pounds at 50 psi.Which is better Load Range C or D?
The difference between an load range C and load range D tire in the same size is the capacity and psi rating. … The D rated tire has a higher capacity. For a ST175/80D13 like # AM1ST77, the capacity is 1,610 pounds at 65 psi. For a C load range in the same size, like # AM1ST76 , the capacity is 1,360 pounds at 50 psi.
Should I run my truck tires at max psi?
In most of these cases, 40 psi should be more than enough, and since most modern tire designs will allow up to 44 psi (in some cases more) this is not a problem. If you have a heavily loaded vehicle, up to 44 or even higher is ok if the tire allows it, but this is a little high for most vehicles.
Do XL tires need more pressure?
The load capacity of a reinforced tyre also decreases with decreasing air pressure, so XL tyres need higher air pressure. This is the only way to ensure a higher load-bearing capacity. The stipulated tyre speed rating and load index of your XL tyres can normally be found in the last characters on the sidewall.
What is the difference between 10 ply and 14 ply tires?
A tire in the same size but with a higher ply rating would be able to combat some of that but can eventually have the same issues. So when inflating trailer tires be sure to go to the max psi. With that said the 14 ply tires will definitely hold up better than the 10 ply. … It is rated for 4,080 pounds at 110 psi.What's the best speed rating for tires?
SPEED SYMBOLSSymbol SpeedSpeed (km/h)Speed (mph)A153A2106A3159
What does LRD mean on a tire?ST-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.
Article first time published onWhat does load B mean on tires?
Most alphanumeric tires feature a load range of B, which indicates that they are restricted to the load that can be carried at a maximum inflation pressure of 32 psi. … Standard Load tires are limited by the load that can be supported with a maximum inflation pressure of 35 psi.
How much weight can a load range B trailer tire carry?
On special trailer tires and light truck tires the Load Range B means it is a 4 ply rated tire with a maximum load of 1,430 lbs.
What are tire load ranges?
A tire’s ‘Load Range’ can be found on the tire’s sidewall represented by a letter, usually after the tire size (35X12. 50 R17/E for example). This code represents the ability of the tire to hold air and weight; the higher the load range (A→G) the heavier load the tire can carry.
Is Load Range D or E better?
Expert Reply: Load range D has a capacity of 1,220 lbs at 65 psi, whereas load range E has a capacity of 1,520 lbs at 80 psi. Basically the only difference between the two is the weight capacity.
What are the different load ranges for trailer tires?
The load range on trailers are classified as B, C, D, or E. B is the lightest classification of load capacity and E carries the heaviest load capacity. Most boat trailer tires fall under C or D. If boat trailer tires hold a C Load that means it can carry up to 1,820 lbs.
Can you tow with D rated tires?
For driving unloaded it would be fine. If you are running much lower than the >tire< rated psi then yes. D or e rating makes little difference aside from being an old way of rating tires but is a quick reference. The load index rating can be higher on d rated tires than e rated based on tire size.
What does 115T mean on a tire?
The 115T signifies that the tire has a 4ply standard load sidewall. The 121S signifies a 10 ply load range E sidewall. The standard load tire is best for a half ton truck, whereas the load range E sidewall is best for a 3/4 and 1 ton truck.
What does C1 mean on tires?
“C1” and “C2” are both 6 ply rated, but C1 has a max air pressure of 50 PSI and C2 has a max air pressure of 35 PSI. This holds true for other ply ratings too. Tires on a sedan, coupe, crossover or minivan are usually unmarked because they have a standard 4-ply rating and do not require higher load carrying abilities.
What is load range E1?
Now comes a comparison of E1 vs E2 load range. As I feebly understand Discount Tire’s own material, E-rated tires sized 305 and up carry an E-2 load range and a max inflation of 65 psi while E-rated tires sized below 305 carry an E-1 load range and a max inflation of 80 psi.
Is 35 tire pressure too high?
Higher pressure generally is not dangerous, as long as you stay well below the “maximum inflation pressure.” That number is listed on each sidewall, and is much higher than your “recommended tire pressure” of 33 psi, Gary. So, in your case, I’d recommend that you put 35 or 36 psi in the tires and just leave it there.
What should tire pressure be in hot weather?
If tires are warm from being driven, set pressures 4 psi above recommended in the morning and 6 psi if checked and set in the afternoon.
Is 40 PSI OK for tires?
If there’s no sticker, you can usually find the info in the owner’s manual. Normal tire pressure is usually between 32~40 psi(pounds per square inch) when they are cold. So make sure you check your tire pressure after a long stay and usually, you can do it in the early morning.
What happens if you go faster than tire speed rating?
If you go way over the rating, or if you stay above the rating for more than a few minutes, the tire may fail, losing tread or blowing out. The speed rating is an estimate of how much heat the tire can handle before it is damaged. The heat buildup comes from the speed combined with the load.
Are trailer tires speed rated?
Trailer tires commonly have tire speed ratings in the 65 – 75 mph range. Unless otherwise noted, the speed rating for trailer tires is 65 mph.
What does H mean in tires?
The speed rating on a tire indicates the fastest speed a tire can handle before it affects the tire’s performance. … For example, “H” would translate to a tire that can only handle speeds up to 130 mph (or 210 km/h).
Is a higher ply tire better?
The more ply, the more sidewall strength. When your sidewall isn’t strong enough, the load squashes the tires down into the road. The tread then pushes into the ground and spreads out in a way that was never intended by the manufacturer, leading to a blowout.
What is the highest load range for a trailer tire?
This article focuses on 14 ply trailer tires (load range G), which is the highest capacity you can get. 14-ply rated trailer tires can sustain pressures of up to 110 psi (760 kPa), and weight of over 4,000 lbs per tire.
What ply tires do I need for towing?

What does LRA mean on a tire?
The load range system uses letters to indicate how many plies the tire is. Here is a useful chart to help you: Load Range A (LRA) = 2 ply. Load Range B (LRB) = 4 ply. Load Range C (LRC) = 6 ply.
