Deciphering Truck Tire Terminology
Many truck owners do not know the difference between p-metric and LT tires and which is better for their vehicle. If you drive a pickup truck, large SUV, or a panel van, you should know the difference between these size designations. A replacement of the exact tire that came on the vehicle originally may not always be the right choice for the replacement tire.
Tire sizes with a “p” in front of the numbers in the size description, or no letter, are p-metric. If an LT is in front of the size, it is an LT tire. Which tire type is right for you depends on your vehicle’s use.
The world of truck tires can be a tad confusing, especially when faced with terminologies like P-metric and LT. Choosing the right type is not just about fitting rubber to your truck’s wheels; it’s about safety, performance, durability, and matching your driving habits. So, let’s help you unravel this tire puzzle!
Understanding the Basics of P-metric and LT Tires
When diving into the world of tires, particularly for trucks and SUVs, two common terms emerge P-metric and LT. To make an informed choice, it’s vital to understand what each of these designations means and their intended applications.
P-metric Tires: The Passenger’s Choice
- Origin: The term “P-metric” is derived from the word “passenger,” indicating that these tires are primarily designed for passenger vehicles.
- Vehicle Suitability: These are ideal for various vehicles, from sedans to crossovers, some SUVs, and even light-duty trucks. They are tailored for cars that aren’t typically subjected to heavy-duty workloads or rough off-road terrains regularly.
- Ride Comfort: P-metric tires usually have a flexible sidewall, translating to a smoother and more comfortable ride. This makes them a preferred choice for everyday commuting or highway cruising.
- Load Handling: While they can manage light to moderate loads efficiently, they might not be the best choice if your vehicle frequently carries heavy cargo or tow trailers.
LT Tires: Built for the Task
- Designation: The “LT” stands for “Light Truck.” However, this can be misleading, as these tires are suitable for light trucks and those built for heavier tasks.
- Durability and Strength: LT tires are built with reinforced sidewalls and more rigid materials, enabling them to handle rough terrains, resist punctures, and carry heavier loads.
- Vehicle Suitability: From pickup trucks to larger SUVs to heavy-duty trucks, LT tires are the go-to choice for vehicles that require enhanced durability and load-bearing capacity.
- Performance in Tough Conditions: Whether venturing off-road, towing a trailer, or carrying a bed full of construction materials, LT tires are designed to handle the added stress and rough conditions.
- Ride Feel: Due to their robust construction, LT tires might offer a stiffer ride than their P-metric counterparts. This rigidity, however, ensures that they can handle heavier weights and tougher terrains without faltering.
Choosing between P-metric and LT tires involves understanding your vehicle’s requirements and your regular driving conditions. It’s essential to assess your needs and ensure that your tires align with the demands you’ll place on them. Whether prioritizing comfort with P-metric or durability with LT, making an informed choice ensures safety, efficiency, and longevity.
P-metric Tires for More Mileage and a Smoother Ride
Occasionally, tires have a “p” listed in front of the tire size. The “P” in “p-metric” stands for passenger vehicle. Passenger vehicles are cars (for example, sedans or coupes), minivans, or CUVs, but they can also be trucks that do not carry extra heavy loads or run on gravel roads. If there is no letter in front of the size, like the example in this finding your tire size video, the tire is equivalent to a p-metric. These tires have an internal construction and use materials designed to give a smooth ride, good handling on the highway, and to last a long time.
Some pickup truck owners rarely go off paved roads, carry heavy loads, or tow a trailer. Therefore, many half-ton trucks come equipped from the factory with p-metric tires. If you own a half-ton pickup truck or full-size SUV and rarely, if ever, carry a load or go off pavement, then a p-metric tire will be a better choice for your replacement tire. They will ride smoother, last longer, and be more fuel efficient than an LT-rated tire of the same size.
A few tires with a wide range of p-metric sizes that offer good all-around performance and excellent value for your money are the Toyo Open Country H/T tire and the Mastercraft Courser HSX Tour tire. The p-metric sizes in both these tire styles come with a 60,000-mile tread-wear warranty for long mileage.
If your truck, van, or full-size SUV comes from the factory rated for LT tires, replacing them with LT tires is best. P-metric to LT is acceptable, but never replace original equipment LT tires with P-metric tires because they have lower load capacity ratings at maximum air pressure.
LT Tires for Heavy Loads, Towing, and Off-Road Durability
LT tires are going to be more expensive than p-metric tires. This is because LT tires have extra material in the sidewall and under the tread that protects the tire from damage. The cords in an LT tire are a larger gauge than P-metric tires so that the tire can carry heavier loads.
LT tires often have an extra steel belt, a deeper tread, and thicker sidewall rubber for more protection than a p-metric tire. LT tires are usually 8-ply (Load Range D) or 10-ply (Load Range E). Passenger Tires generally have a 4-ply or 6-ply equivalent sidewall. The performance trade-off of this added weight is a harsher ride, less fuel efficiency, and less responsive handling.
Tread-wear or tire mileage is typically about the same for LT and P-metric tires, except if used often on gravel roads. If used on gravel roads, you should consider an LT tire instead of a p-metric because the tread rubber in LT tires is usually specially formulated to resist chipping from stones. On paved highways, p-metric tires typically have better wet and dry traction on pavement.
If you drive your truck heavily loaded or pull heavy trailer loads frequently, you should consider replacing your p-metric tire with an LT tire. Tradespeople who have their vehicle or van loaded with tools, supplies, and equipment often find stiffer LT tires provide less sway and, therefore, more confidence-inspiring handling.
Others may find that the ride is slightly harsher and not as comfortable. This is one of the trade-offs you can expect when you replace a p-metric tire with an LT tire. A tough, durable LT tire for hardworking trucks and commercial vans is the Cooper Discoverer STT Pro Tire.

FAQs
Should I get P or LT tires?
Your choice between P (Passenger) and LT (Light Truck) tires depends on your driving habits and vehicle requirements. P-metric might be ideal if you prioritize a smoother ride, don’t frequently haul or tow heavy loads, and drive mainly on highways or urban roads. LT tires would be more appropriate if you often carry heavy loads, tow trailers, or go on rough terrains.
Should I put LT tires on my truck?
LT tires are a good choice due to their reinforced construction and higher load capacity if you use your truck for towing, hauling heavy loads, or off-road driving. However, P-metric tires might suffice if you primarily use your vehicle for everyday commuting or light duties.
Can I put P tires on my truck?
You can put P tires on your truck if it’s primarily used for daily commuting or light duties and doesn’t frequently carry heavy loads. However, ensuring the tires can support the truck’s gross vehicle weight rating (GVWR) is essential. Always consult your vehicle’s manual or a tire specialist before switching.
Do LT tires last longer than P?
LT tires are generally more durable and built with stronger sidewalls, making them more resistant to punctures and wear, especially under heavy loads or rough terrains. However, the longevity of any tire, whether P-metric or LT, depends on factors like driving habits, maintenance, load carried, and road conditions. While LT tires might be built to last longer under more challenging conditions, P-metric tires could have a comparable lifespan under lighter use.
