If you regularly tow a trailer, haul heavy loads, or run your F-150 close to its rated payload, the standard highway tire that came on many trims may genuinely be under-built for the job. This guide covers what “LT-rated” means, why it matters for towing specifically, and how to choose the right one. For full sizing across every F-150 generation, see our Ford F-150 Tire Guide.

What “LT-rated” actually means
LT stands for Light Truck. An LT tire is built with a reinforced sidewall and internal construction to carry meaningfully more weight than a standard passenger (P-metric) tire of the same nominal size, identified by an “LT” prefix on the sidewall (e.g. LT275/65R18) rather than a “P” prefix or no letter at all. That extra capacity is exactly what towing and heavy hauling call for.
Load range — the number that matters most for towing
LT tires are further categorized by load range (commonly C, D, or E), which determines how much weight the tire safely carries at its rated pressure — a higher letter generally means a higher load capacity, but also a firmer ride and, often, a higher recommended pressure. Running a tire under-rated for your actual loaded weight (truck plus trailer tongue weight, or truck plus cargo) is a real safety issue: reduced control, faster wear, and real risk of tire failure under sustained load. If you’re not sure what load range you need, bring us your truck’s payload and towing figures (found on your door-jamb sticker or owner’s manual) and we’ll help you match it correctly.
When you actually need LT tires
- You tow a trailer, camper, or boat regularly — not just an occasional light load.
- You haul heavy cargo (equipment, materials, tools) on a regular basis.
- You run close to your F-150’s maximum rated payload.
If you’re mostly commuting light and towing rarely and lightly, a standard highway tire is usually fine, and an LT tire’s firmer ride may be more trade-off than you need.
LT tires and tread type
LT load range and tread pattern (highway, A/T, M/T) are independent choices — you can get an LT-rated tire in a smooth highway tread or an aggressive all-terrain tread. If you tow and also want off-road capability, look for an LT-rated version of an A/T line like those in our all-terrain tire guide.
Other things worth knowing before you tow
- Tire pressure changes under load — LT tires typically call for higher cold pressure when loaded/towing than when running empty; check your door-jamb sticker and owner’s manual for the specific figures.
- Replace in full sets where possible — especially important on 4WD trucks, since mismatched tread depth or diameter across the four wheels can stress the drivetrain (see our main F-150 tire guide for more on 4WD replacement guidance).
- TPMS relearn — typically needed after any tire replacement.
Concord Tires sees a lot of F-150s set up for towing boats and trailers out toward the Delta — if you’re weighing load range for your specific setup, bring us your truck’s payload and towing figures and we’ll help you match it — we fit LT tires near Concord, Walnut Creek, Pleasant Hill, Clayton, Martinez, and Pittsburg.
FAQ
Do I need LT tires to tow a small trailer with my F-150?
Not necessarily — it depends on your total towed weight and your truck’s payload rating relative to your standard tire’s load capacity. Bring us the specifics and we can tell you.
Can I mix LT and standard tires on the same truck?
No — mixing load ranges or tire types across your four wheels is a real safety and handling risk, especially on a 4WD truck. Replace in a matched set.
Does an LT tire ride worse than a standard tire?
Generally yes, somewhat — the reinforced construction that gives it more load capacity also makes it a bit firmer, especially when run empty. It’s a fair trade-off if you actually tow or haul regularly.
