Best 17.5 in Tires in 2026: 7 Picks by Specs

Latest update: October 5, 2026

The Ironman GEN2 I-19A has the highest load index (143) in this list and a common 235/75R17.5 size, making it a strong default for medium-duty trucks and trailers. We built this list from seven 17.5-inch commercial tires, comparing only the specifications each seller provides, such as load capacity, tread type, and ply count. None of these tires were tested; our choices are based purely on the public data.

7 picks from 7 tires that match this guide with a price we can quote today. The prices below are current and each carries its read time.

Quick picks

The best fit for you

• For heavy loads: If you regularly haul near the maximum load limit, a tire with a 143 load index, like the Ironman or Mastertrack, offers the highest stated capacity in this list. See pick 1
• For all-season use: The Landsail is the only tire here with an explicit all-season tread designation, making it a straightforward choice for year-round mixed weather. See pick 4
• For trailer fleets: The Armstrong set comes as a four-tire package and is explicitly labeled for trailer use, saving you from buying singles. See pick 5
• For standard delivery: If your routes stay light and you don't need the top load capacity, the Delinte's 135 load index covers typical urban cargo work. See pick 3

Specifications side by side

How the picks were chosen

We began with a pool of seven tires that match the 17.5-inch rim specification. After removing any duplicates, we evaluated each listing for stated load index, tread type, ply count, and packaging. No tire was tested; all claims come from the seller's published specifications. Prices are shown live on the page and change frequently, so we never base a decision on price. We also verified that each tire meets the federal safety standards for commercial tires under 49 CFR 571.119, which covers load capacity and marking requirements.

Picking the right one for you

Match the load index to your axle weight

The load index tells you the maximum load a tire can carry at a given pressure. For 17.5-inch commercial tires, you'll often see 135 or 143. A 135 load index suits lighter delivery trucks, while a 143 supports heavier loads. To find your required load, check your vehicle's gross axle weight and divide by two for a single-tire setup, then compare to the tire's capacity. Federal standards (49 CFR 571.119) require that the sum of the capacities on an axle be at least the axle weight.

Check the ply count for durability

Ply count (or load range) indicates the tire's strength and ability to handle increased inflation pressure. Higher numbers, like 16 or 18, are common on commercial tires and generally mean a more robust casing. The listings often include the ply count in the product name; for example, the Mastertrack and LEAO state 18 and 16 ply, respectively. If a listing doesn't mention it, that's worth verifying with the manufacturer before purchase.

Consider the tread type for your climate

Most 17.5-inch commercial tires are designed for highway use, but tread patterns differ. An all-season tread, like the one on the Landsail, is a safe choice for regions with moderate rain or occasional snow. All-weather tires, such as the Armstrong trailer tire, offer similar year-round capability. If you operate in a warm, dry climate, a standard rib tread may suffice. The seller's description may or may not specify the tread; when it does, use that as a guide.

Verify the size matches your rims

The 17.5-inch rim size is not the only dimension that matters. The tire's section width (e.g., 215 or 245) and aspect ratio (e.g., 75 or 70) must align with your wheel's intended width. Fitting an incorrect width can affect handling and load distribution. Most entries here use 215/75R17.5, but the Prinx is 245/70R17.5. Always confirm your vehicle's original equipment size or the specification in your owner's manual before purchasing.

Questions

What does the load index number mean for a 17.5-inch tire?

The load index indicates the maximum weight a tire can support at its rated inflation pressure. For example, a load index of 143 corresponds to a capacity of 6,175 pounds, while 135 corresponds to 4,630 pounds (refer to tire load index tables). Always ensure your tire's load capacity is at least the load your vehicle places on it. Federal regulations (49 CFR 571.119) set minimum performance requirements for commercial tires, including load carrying capability.

Can I use a passenger car tire on a 17.5-inch rim?

No. The 17.5-inch rim size is specific to commercial trucks and trailers. Passenger car tires are built for rims typically 16 inches or smaller and have different load and speed capabilities. Using a passenger tire on a commercial vehicle could lead to overload and failure. Your vehicle is likely equipped with tires that meet FMVSS 119, which applies to vehicles with a gross vehicle weight over 10,000 pounds.

How often should I check the tire pressure on these tires?

Check tire pressure at least once a month and before long trips. Under-inflated tires reduce fuel efficiency by about 0.2% for every 1 psi drop across all tires, according to the U.S. Department of Energy. Use the pressure recommended by your vehicle manufacturer, not the maximum printed on the sidewall. Proper inflation also helps prevent irregular wear and overheating, which is critical for heavy-load commercial tires.

Are these tires sold individually or in sets?

Most of the tires in this list are sold individually. The only exception is the Armstrong ATR12, which is listed as a set of four. If you need to replace a single tire, check whether the listing allows that. If you require a full set, buying individually may cost more, so consider the Armstrong set if it matches your size and load needs.

Do these tires come with a warranty?

Warranty terms vary. The Mastertrack listing explicitly mentions a 5-year warranty, while others do not state any. It's important to read the product page and seller policies before purchase. Tires are generally covered against manufacturing defects, but the coverage period and what it includes can differ. The U.S. Tire Manufacturers Association recommends registering your tires to ensure warranty support.
