Where to buy 16.5 truck tires for sale and what you need to know

If you're searching for 16.5 truck tires for sale, you're likely dealing with older or specialty off-road vehicles that use this less common rim diameter. Unlike standard 16-inch or 17-inch tires, 16.5-inch wheels are not compatible with most modern radial tires and require specific bias-ply or special-design radials. This guide breaks down everything you need to know—from available sizes and top-performing models to where to buy, compatibility warnings, and whether upgrading your rims might be a smarter long-term choice.

Why 16.5-Inch Truck Tires Are Hard to Find

🛒 The first thing every buyer should understand is that 16.5-inch wheel diameters are largely obsolete in mainstream automotive manufacturing. They were commonly used on heavy-duty light trucks, military surplus vehicles, older dually pickups (like certain Ford F-350s from the '80s and '90s), and industrial equipment during the 1970s–1990s1.

🔧 Today, most tire manufacturers have shifted focus to radial construction on standardized rim sizes like 16", 17", 18", etc., which support better fuel economy, ride comfort, and highway safety. As a result, the selection of new tires designed specifically for 16.5-inch rims is limited—and mostly focused on rugged off-road or industrial applications.

❗ This creates a real challenge: if your vehicle still runs on 16.5 rims, you’re locked into a niche market. You won't find these at typical auto chains or big-box retailers. Instead, sourcing them requires targeted research, understanding load ratings, and knowing which brands still produce compatible options.

Common 16.5 Truck Tire Sizes and Their Applications

📏 When shopping for truck tires 16.5 for sale, size designation follows an older format—often using flotation or numeric sizing instead of the alphanumeric P-metric system (e.g., P235/75R15). Here are the most frequently encountered 16.5-inch tire sizes:

• 10.00-16.5 – Common on older commercial vans, delivery trucks, and some dual rear wheel (DRW) pickups
• 12-16.5 – Found on heavier utility vehicles, farm tractors, and industrial machinery
• 8.75-16.5 – Often seen on lighter-duty applications including older SUVs and Jeeps
• 33x12.50-16.5 – A popular off-road size for modified trucks needing aggressive tread depth
• 37x12.50-16.5 – Used by serious rock crawlers and overland rigs running classic Super Swamper-style tires

📌 These sizes indicate overall height and width rather than section width and aspect ratio, making direct comparisons with modern metric tires difficult. Always verify fitment based on your wheel width, clearance, and intended use.

Bias-Ply vs Radial: Critical Differences for 16.5 Tires

⚙️ One of the most important technical decisions when buying 16.5 truck tires is choosing between bias-ply and radial construction. Most 16.5-inch tires available today are bias-ply, but there are exceptions.

Feature	Bias-Ply (Most 16.5)	Radial (Rare)
Construction	Crisscrossed fabric layers	Steel belts + radial cords
Ride Comfort	Firm, bouncy	Smoother on pavement
Durability Off-Road	Excellent puncture resistance	Good, but sidewalls more vulnerable
Fuel Efficiency	Lower due to higher rolling resistance	Better than bias-ply
Availability	Widely available for 16.5	Limited; only select brands

✅ Bias-ply tires remain dominant in the 16.5 category because they’re built for durability under extreme loads and rough terrain. However, they generate more heat on highways and wear faster. Radial versions—such as the Interco Super Swamper SSR series—are engineered for improved performance but come at a premium price and limited availability2.

Top Brands Still Making 16.5 Truck Tires

🏭 While many mainstream tire companies no longer offer 16.5-inch options, several specialized manufacturers continue producing high-quality tires for this niche:

• Interco Tire – Offers one of the widest selections of 16.5-inch off-road tires, including the legendary Super Swamper TSL, TrXus, and Irok lines in both bias and radial constructions.
• Goodyear – Produces the Wrangler MT (mud terrain) in LT37X12.50R16.5, though availability is limited to select dealers.
• BKT – Known for industrial-grade tires like the Mud Power HD, available in 10-16.5 and other sizes ideal for heavy utility use.
• Carlisle – Manufactures the Trac Chief, a cost-effective option for agricultural and landscaping vehicles.
• Samson – Supplies rugged all-terrain and mud-terrain tires such as the Sidewinder Mudder XHD, often found in 12-16.5 configurations.
• TreadWright – Specializes in retreaded all-terrain and mud-terrain tires for off-roaders seeking affordable replacements.

🔍 It's worth noting that even among these brands, inventory fluctuates. Some models may only be available through specialty distributors or made-to-order.

🚚 Shipping costs and delivery times vary significantly due to tire weight and low stock levels. Expect longer lead times—especially for larger flotation sizes like 37x12.50-16.5.

Compatibility and Fitment Warnings

⚠️ Before buying any 16.5 truck tire, confirm two critical factors:

1. Rim Compatibility: 16.5-inch rims have a unique bead seat design that prevents standard radial tires from seating properly. Attempting to mount a regular radial tire on a 16.5 rim can lead to blowouts or sudden deflation.
2. Vehicle Clearance: Larger flotation tires (e.g., 37-inch tall) may require suspension lifts, fender trimming, or steering modifications. Check your axle, brake, and suspension geometry before upgrading.

📋 Also pay attention to load range (e.g., Load Range E/10-ply rated) and speed rating. Many 16.5 tires are rated for lower speeds (N-rated = 87 mph max), which limits highway driving suitability.

Are 16.5 Tires Worth Keeping? Or Should You Upgrade?

👥 This is a common debate in forums like Reddit’s r/trucks and Ford Powerstroke owner groups. Many experienced owners suggest replacing 16.5 rims with modern 16” or 17” wheels to unlock access to a broader range of tires, better ride quality, and improved resale value.

✨ Benefits of switching:

• Access to thousands of modern radial tire options
• Better fuel efficiency and quieter ride
• Easier future maintenance and replacements
• Potential increase in vehicle resale appeal

❗ Downsides:

• Upfront cost of new wheels
• Labor involved in mounting and balancing
• Potential need for hub adapters or lug pattern changes

✅ Ultimately, the decision depends on how you use your truck. If it’s primarily off-grid, work-focused, or part of a restoration project, sticking with 16.5 may make sense. But if you drive regularly on paved roads, consider upgrading for long-term convenience.

Cost Range and Value Considerations

💰 Prices for 16.5 truck tires vary widely depending on brand, size, and construction:

• $110–$170: Entry-level industrial tires (e.g., Carlisle Trac Chief)
• $230–$350: Mid-tier all-terrain or mud-terrain options (e.g., BKT Mud Power HD)
• $400–$650: Premium bias-ply off-road tires (e.g., Interco Super Swamper TSL)
• $700+: Large flotation radials or rare sizes (e.g., 38x15.5R16.5)

📌 Keep in mind that cheaper tires may lack advanced rubber compounds or robust sidewall protection. For heavy-duty or off-road use, investing in higher-end models often pays off in longevity and safety.

Frequently Asked Questions (FAQ)

Can I put regular radial tires on 16.5 rims?

No. Standard radial tires are not designed for 16.5-inch rims, which have a different bead seat profile. Only tires explicitly labeled for 16.5-inch diameter should be used. Using incompatible tires risks improper seating, air loss, and dangerous failures.

What does '10.00-16.5' mean in tire sizing?

This is an older numeric sizing system. '10.00' refers to the tire's approximate width in inches, and '16.5' is the rim diameter. There is no aspect ratio specified—it's assumed based on construction type. Always match replacement tires exactly unless changing rims.

Are 16.5 truck tires still being made?

Yes, but only by select manufacturers for niche markets. Companies like Interco, BKT, and Goodyear still produce 16.5-inch tires, primarily for off-road, industrial, or military applications. Availability is limited compared to standard sizes.

Do 16.5 tires come in all-season or highway terrain types?

Very few. Most 16.5-inch tires are designed for mud-terrain or all-terrain use. True all-season or highway terrain options are nearly nonexistent due to low consumer demand and production focus on durability over comfort.

Where can I get my 16.5 tires mounted locally?

Finding a shop willing to mount 16.5 tires can be difficult. Look for off-road specialty garages, heavy equipment service centers, or agricultural tire dealers. Call ahead to confirm experience with non-standard rim diameters.
