Load Range C tires can carry a maximum of 2,029 pounds per tire when inflated to their rated pressure
Load range is a letter code that tells you how much weight a tire can safely support. Load Range C is the lightest duty rating you'll see on passenger vehicle tires. It appears on the tire's sidewall as a single letter — C, D, E, or higher — and it matters because overloading a tire causes it to overheat, wear unevenly, and fail suddenly.
The weight capacity depends on the tire's size and construction. A Load Range C tire is built with fewer reinforcing plies (layers of cord and rubber) than heavier-duty tires. The maximum weight it can carry is printed on the tire sidewall next to the load range letter. You need to know this number to make sure your tires match what your vehicle actually weighs.
Key Takeaways
- Load Range C is the standard rating for most passenger cars and light sedans, and the sidewall shows the exact maximum weight each tire can hold.
- You must check your vehicle's door jamb label or owner's manual to find the correct load range for your specific make and model — do not guess based on what you see on the road.
- Underinflating a Load Range C tire reduces its weight capacity, so maintaining the pressure listed on your door jamb is part of staying within safe limits.
- Upgrading to a heavier load range (D or E) is possible but requires tires that fit your wheel size, and you should verify the change with your vehicle's manufacturer or a tire professional.
How load range connects to tire construction
Load range is determined by how many plies — reinforcing layers — are built into the tire's sidewall and tread. Load Range C tires typically have two plies in the sidewall. Each additional ply adds strength and allows the tire to carry more weight, which is why Load Range D and E tires are thicker and heavier.
The more plies a tire has, the more it costs to manufacture, and the stiffer it feels when driving. This is why passenger cars use Load Range C: the tire is light enough to give a smooth ride and good fuel economy, and it's strong enough for the vehicle's actual weight. Trucks and vehicles that tow or carry heavy loads use Load Range D or E instead.
Finding the correct load range for your vehicle
Your vehicle has a specific load range requirement, and it's not based on the tire size alone. Open your driver's side door and look at the label on the door jamb — it lists the tire size, the load range, and the inflation pressure your manufacturer recommends. This label is the source of truth for your vehicle.
Your owner's manual also contains this information. Never assume your current tires are correct just because they fit the wheel. A tire that is the right size but the wrong load range can be unsafe, even if it physically mounts on your vehicle. If you're unsure, a tire shop can read your door jamb label and confirm what you need.
The relationship between load range and tire pressure
A tire's weight capacity is only valid when the tire is inflated to its rated pressure. Load Range C tires are typically rated at 32 to 36 pounds per square inch (psi), though this varies by tire size. If you underinflate a tire — run it at 28 psi instead of 32 psi, for example — the tire cannot support its full rated weight, and the sidewalls flex more, causing heat buildup.
Check your tire pressure monthly with a reliable gauge. The pressure on the tire's sidewall (the maximum pressure the tire can hold) is different from the pressure your vehicle needs. Always use the pressure on your door jamb label, not the number on the tire itself. Keeping tires at the correct pressure protects both the weight capacity and the tire's lifespan.
When you might need a different load range
If you regularly carry passengers and cargo that approach or exceed your vehicle's weight rating, or if you're towing, you may need to move to a heavier load range. Load Range D tires can carry roughly 10 to 15 percent more weight than Load Range C, depending on the tire size. Load Range E is heavier still.
Changing load range requires buying tires in a different size or construction, and it affects how your vehicle handles and rides. Before making this change, check your vehicle's maximum load capacity (also on the door jamb label) and talk to a tire professional or your vehicle's manufacturer. Some vehicles cannot safely use a heavier load range because the suspension and brakes are not designed for it.
Reading the load range on your tire sidewall
The load range letter appears on the tire's sidewall, usually near the tire size. You'll see something like "P205/55R16 91H C" — the C is the load range. The number before the letter (91 in this example) is the load index, which is a shorthand for the weight capacity. You can look up the load index in a chart to find the exact weight, but the easiest method is to call a tire shop and give them the tire size and load range; they can tell you the capacity in seconds.
If you cannot find the load range on your tire, check the sidewall carefully — it may be printed in smaller text. If it's still not visible, the tire may be very old or damaged. In that case, replace it and use the door jamb label to order the correct replacement.
Common mistakes people make with load range
The most common mistake is ignoring the load range entirely and assuming that if a tire fits the wheel, it's safe. Another mistake is confusing load range with load index — they're related but not the same thing. Load index is a number; load range is a letter. Both appear on the sidewall, and both matter.
People also sometimes underinflate tires thinking it will make the ride softer, not realizing that underinflation reduces weight capacity and causes the tire to overheat. If your ride feels harsh, the problem is usually worn suspension components, not tire pressure. Stick to the pressure on your door jamb label.
Frequently Asked Questions
Can I put Load Range D tires on a vehicle that came with Load Range C?
Only if the tire size and load index match what your manufacturer recommends. Load Range D tires in the same size as your original Load Range C tires will fit physically, but you should verify with your vehicle's manual or a tire professional that the change is safe. Some vehicles' brakes and suspension are not designed to handle the stiffer ride of a heavier load range.
What happens if I drive on an underinflated Load Range C tire?
The tire cannot support its rated weight, and the sidewalls flex excessively. This causes the tire to overheat, wear unevenly, and fail sooner than expected. Underinflation also reduces fuel economy and makes steering less responsive. Check pressure monthly and inflate to the number on your door jamb label, not the maximum on the tire sidewall.
Is Load Range C safe for a sedan with four passengers and luggage?
Yes, if the total weight stays within your vehicle's maximum load capacity (listed on the door jamb). Load Range C is designed for passenger cars and light sedans. If you frequently exceed the vehicle's rated capacity, you may need a different vehicle or a heavier load range, but this requires checking with the manufacturer first.
How do I know if my tires are Load Range C?
Look at the sidewall of your tire for a single letter code, usually near the tire size. You can also check your door jamb label or owner's manual, which lists the load range your vehicle requires. If you're buying replacement tires, give the tire shop your vehicle's year, make, and model, and they'll confirm the correct load range.
