1989 Ford Trucks Tire Fitment Guide

1989 Ford Trucks vehicles use nine radial sizes across six model lines: 235/75R15 and 31X10.50R15 for the Bronco, 205/75R15 for the Bronco II, 215/75R15 and 235/75R15 for the F-150, 215/85R16, 235/85R16, and 7.50R16 for the F-250, 215/85R16 and 235/85R16 for the F-350, and 195/70R14, 215/70R14, and 215/75R15 for the Ranger. Rim diameters span 14, 15, and 16 inches, and rim width ranges vary by size where tire options spell them out.

That means year and make alone are not enough for this page's full truck range. A Ranger can use either 14-inch or 15-inch tires depending on application, while an F-250 can take one of three different 16-inch sizes. Start by confirming the exact model, then verify the wheel diameter already on the truck and compare the tire's approved rim width range to the actual wheel before making a final choice.

On a 1989 Ford Trucks tire, 31X10.50R15 is a flotation-style radial size. The first number is the tire's approximate overall diameter in inches, the second is the nominal section width in inches, the R identifies radial construction, and the final 15 is the wheel diameter in inches. In this application, that size belongs to the 1989 Ford Trucks Bronco and mounts on a 15-inch wheel.

That sizing format is common on truck and off-road tires because it emphasizes overall height and width more directly than a metric code. For a Bronco owner, it points toward a taller, broader truck look than a conventional 235/75R15. It is still important to confirm wheel width and clearance before choosing it, especially if the truck has been altered from stock ride height or wheel specification.

No. 1989 Ford Trucks covers compact pickups, sport-utilities, half-ton trucks, and heavy-duty work trucks, so tire size varies substantially by model. Some sizes are shared between two models, such as 235/75R15 on the Bronco and F-150, 215/75R15 on the F-150 and Ranger, and the 16-inch 215/85R16 and 235/85R16 sizes on the F-250 and F-350. Others are model-specific, including 205/75R15 for the Bronco II, 31X10.50R15 for the Bronco, 7.50R16 for the F-250, and the two 14-inch Ranger sizes.

The practical takeaway is simple: identify the model first, then check the wheel diameter already fitted. That matters even more on the Ranger and F-250, where more than one diameter or size family appears. Once the correct size is confirmed, sidewall style and brand choice become easier to narrow down without risking a mismatch between tire and wheel.

1989 Ford Trucks tires span a wide range of sidewall styles depending on size. Truck-oriented fitments such as 31X10.50R15 and 235/85R16 appear in RWL form, while 235/75R15 can be found in RWL, narrow whitewall, and wide whitewall versions. 205/75R15 adds goldline and whitewall choices, 215/75R15 includes RBL, narrow whitewall, and wide whitewall, 195/70R14 is offered as a blackwall, and 215/70R14 reaches across RWL, blackwall, pin-white-stripe, and narrow whitewall styles.

For a stock late-1980s truck or SUV, blackwall, raised white letter, or restrained stripe treatments usually look most natural. Whitewalls and goldlines are more of a custom or period-accessory appearance choice than a factory-style Ford truck presentation for this era. Once the size is settled, sidewall style becomes the visual decision that most strongly affects whether the truck reads as work-ready, sport-truck inspired, or deliberately customized.

Several brands cover 1989 Ford Trucks sizes, depending on the application. BFGoodrich appears across 235/75R15, 31X10.50R15, 205/75R15, 215/75R15, and 235/85R16. American Classic, Maxxis, and Coker Classic support some 15-inch fitments, Tornel covers 205/75R15 and 215/75R15, Dunlop offers 195/70R14, and 215/70R14 is available from Cooper, Michelin, BFGoodrich, and Maxxis.

Brand choice often follows the character of the truck and the look you want. BFGoodrich and Cooper skew more toward truck or performance-oriented visual cues, while American Classic, Coker Classic, and some BFGoodrich Silvertown offerings lean toward restoration-style sidewalls. Matching the brand and series to the truck's role can help a Bronco, Ranger, or F-Series look more coherent than simply choosing by size alone.

In 215/70R14 for 1989 Ford Trucks, BFGoodrich offers a Silvertown Radial with a pin-white-stripe sidewall, a 1,554-lb load figure at 35 psi, and an approved rim width range of 5.50 to 7.00 inches. Michelin offers the XWX as a blackwall radial with a W speed rating, a 168 mph ceiling, TL marking, and an approved rim width range of 5.50 to 7.50 inches. They serve the same size but present very different sidewall character and speed-rating emphasis.

For a Ranger owner, that means the choice is less about basic fitment than about appearance and tire personality. The BFGoodrich option suits a period-custom or striped sidewall look, while the Michelin reads as a cleaner blackwall road tire with a higher stated speed ceiling in the marking. Wheel width should be checked carefully, since Michelin accepts a slightly broader rim range within the same nominal size.

Rim width depends on the exact size. 235/75R15 products fit wheels from 6.0 to 8.5 inches depending on the tire, 31X10.50R15 fits 7.0 to 9.0 inches, 205/75R15 fits 5.50 to 7.50 inches, 215/75R15 fits roughly 5.5 to 7.5 inches, 235/85R16 fits 6.0 to 7.5 inches, and 215/70R14 fits about 5.5 to 7.5 inches. Some 14-inch and 16-inch applications appear with fewer published choices, so the approved range can be narrower than another tire in the same diameter.

That is why wheel diameter alone is never enough. A 15-inch wheel may accept one tire but fall outside the approved width range for another 15-inch tire of a different section width or intended service class. Before mounting, compare the actual wheel width to the tire's approved range so the sidewall profile, bead seating, and tread shape stay within the tire maker's intended setup.

Most 1989 Ford Trucks tire options shown here are radial designs without a tube-type marking in the size, and one 215/70R14 Michelin carries an explicit TL marking for tubeless use. Tube requirements can still vary by product and by wheel condition, especially on older wheels that have seen corrosion, refinishing, or prior repairs. The tire itself and the wheel both need to be considered together rather than assuming all products in a given size are handled the same way.

For a late-1980s Ford truck or SUV with sound original or replacement tubeless wheels, a modern tubeless radial is often the expected setup. Even so, check the sidewall marking on the exact tire and inspect the wheel carefully before mounting. If there is any doubt about sealing surfaces or prior wheel history, a knowledgeable tire installer or marque specialist can help determine whether the wheel condition changes the setup decision.

Original 1989 Ford Trucks wheels can only be used with tire sizes that match the wheel's diameter first. A 14-inch Ranger wheel cannot take a 15-inch or 16-inch tire, and a 15-inch Bronco or F-150 wheel cannot accept a 14-inch Ranger or 16-inch F-250 tire. Even within the same diameter, approved rim width range still matters, so not every 15-inch or 16-inch tire is automatically suitable for every original wheel.

That is especially important for trucks with optional wheels, replacement wheels, or years of owner changes behind them. Confirm the wheel diameter stamped on the wheel or measured directly, then compare the wheel width with the tire's approved range. Staying within both dimensions is the safest way to avoid poor tread shape, sidewall stress, or a tire that simply does not mount as intended.

A 1989 Ford Trucks vehicle stores best in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone sources that accelerate sidewall aging. Keep the tires clean, maintain inflation, and move the truck periodically so one footprint is not carrying the load for months at a time. Long-term static storage can encourage flat-spotting, especially on larger light-truck tires with stiff sidewalls.

If the truck will sit for a season or more, slightly reducing the load on the tires with stands under the suspension can help, provided the vehicle is supported correctly and safely. Owners of Broncos, F-Series trucks, and older Rangers often focus on engine or fuel-system storage prep first, but tire care deserves equal attention because the rubber can age out long before the tread is used up.

On a collector or low-use 1989 Ford Trucks vehicle, age matters more than mileage. A good rule is to begin evaluating the tires closely once they are around five to seven years old and to treat about ten years as the point where replacement deserves serious consideration regardless of remaining tread. The DOT date code on the tire sidewall is the best starting point for establishing age.

That guideline matters because many vintage trucks and SUVs spend long periods parked, and time, heat cycles, and environment can weaken the casing even when the tread still looks presentable. A Bronco or F-250 used only for occasional shows, trail rides, or weekend hauling can still be riding on aged rubber. If the truck's use is increasing, an age check should happen before the next long outing.

Tires on a 1989 Ford Trucks vehicle should be inspected before every drive and more thoroughly before any extended trip. Look for sidewall cracking, cuts, bulges, uneven wear, embedded objects, and slow pressure loss, and do not forget the spare. Valve stems also deserve attention because an aging stem can fail even when the tread and casing still look serviceable.

Regular inspection is especially important on older trucks because their use can be sporadic and their duty can vary widely. A Ranger driven only on weekends and an F-350 used for occasional towing both need the same walk-around discipline before heading out. Catching a weathered sidewall or soft tire in the driveway is far better than discovering it after the truck is loaded or already on the highway.

A 1989 Ford Trucks Bronco would have been fitted with radial tires from the factory era, not the bias-ply constructions associated with older collector vehicles. The fitments here are 235/75R15 and 31X10.50R15, both radial sizes on 15-inch wheels, reflecting the late-1980s shift toward modern radial light-truck and SUV tire practice. Original-equipment brand could vary by assembly source, package, and market, so size and construction are the most reliable starting points.

For an accurate restoration, focus first on matching the correct size family for your Bronco and the sidewall look appropriate to how the truck was equipped when new. A raised-white-letter all-terrain look and a more subdued highway-oriented sidewall can both be era-appropriate depending on trim and intended use. If the truck is being restored for judging, consult Ford truck literature or a Bronco marque club for package-specific confirmation.

Yes, correct tire fitment matters on a 1989 Ford Trucks restoration because judges and knowledgeable enthusiasts notice size, profile, sidewall style, and overall visual proportion immediately. A Ranger on a 14-inch blackwall or stripe tire presents very differently from a Ranger wearing a later-style oversized truck tire, and a Bronco or F-Series truck can look incorrect if the wheel diameter or sidewall treatment does not suit the period. Even when the tire physically fits, the wrong presentation can undermine authenticity.

For show use, the goal is not only matching the nominal size but also choosing a sidewall style that aligns with the truck's original character. Late-1980s Ford trucks generally look most natural with blackwall, raised white letter, or restrained stripe treatments rather than wide custom whitewalls. Event standards differ, so owners aiming for concours accuracy should compare against period photos, factory literature, and club guidance before finalizing a tire choice.

In 235/75R15 for 1989 Ford Trucks, BFGoodrich offers an All-Terrain T/A KO2 with an RWL sidewall, a 104S speed rating, a 112 mph ceiling, a 1,985-lb load figure at 50 psi, and a rim width range of 6.0 to 7.0 inches. American Classic offers a radial with a 3-inch wide whitewall, a 2,028-lb load figure at 35 psi, and a broader approved rim width span of 6.00 to 8.50 inches. Both fit the same nominal size, but they create very different visual and usage impressions.

That makes the decision more about presentation and intended character than simple size matching. The BFGoodrich reads as a truck tire with a rugged raised-letter look, while the American Classic leans hard toward a custom or retro-styled appearance uncommon on a factory-stock 1989 Ford truck. Owners restoring a Bronco or F-150 should choose the tire that matches the truck's original personality rather than treating every 235/75R15 as interchangeable in style.

1989 Ford Trucks tires can be appropriate for highway driving when the correct size is used, the tire is in sound condition, and the speed rating matches the intended use. Several of these sizes carry explicit speed markings, including S at 112 mph on 31X10.50R15, 215/75R15, 235/75R15, and 235/85R16, V at 149 mph on 195/70R14, and W at 168 mph on one 215/70R14 Michelin. Many late-1980s Ford trucks and SUVs will reach their practical mechanical limits well before those ceilings become relevant.

Real-world safety depends more on condition, inflation, load, suspension wear, and brake performance than on chasing the highest speed letter in a collector truck. A well-kept Ranger or Bronco on the correct modern radial is generally far more confidence-inspiring than an aged tire with plenty of tread but years of hidden deterioration. Before highway use, inspect the full tire, confirm pressures cold, and be honest about how the truck is actually driven.

Inflation pressure on 1989 Ford Trucks tires should follow the vehicle's factory recommendation as the baseline, then be checked against the reproduction or replacement tire's own rated pressure and load information. The tire range here shows how much that can vary: 235/75R15 runs from 2,028 lbs at 35 psi on one tire to 2,271 lbs at 32 psi on another, 215/75R15 reaches 1,874 lbs at 32 psi on one version and 1,765 lbs at 50 psi on another, and 235/85R16 reaches 3,042 lbs at 80 psi.

Those numbers should not be transferred from one size to another or from one product series to another. The right pressure for a Bronco, Ranger, or F-Series truck depends on the exact tire, vehicle load, and the wheel and suspension setup under that specific truck. Start with the vehicle placard or owner's manual, then confirm the tire's own sidewall and manufacturer guidance before settling on a cold inflation pressure.

Before a longer drive in a 1989 Ford Trucks vehicle, inspect all four tires and the spare for cracking, cuts, bulges, punctures, uneven wear, and proper cold pressure. Confirm that the wheel lug torque, valve stems, and tread depth are all in good order, and pay close attention to any truck that has been sitting for long periods because sidewall aging can hide behind otherwise decent tread. Load-carrying models such as F-250 and F-350 deserve an extra check for proper pressure relative to the expected cargo.

Tires are only one part of the pre-trip picture on an older truck, but they are the part carrying every braking, steering, and load input. It is wise to pair the tire inspection with a broader check of brakes, steering play, fluid levels, lights, and suspension condition before committing to a highway run. That habit is especially valuable on occasional-use Broncos, Rangers, and heavy-duty F-Series trucks returning to the road after storage.
