1990 Dodge Trucks W150 Tires

The 1990 Dodge Trucks W150 uses two radial tire sizes on 15-inch rims: 235/75R15 and 31X10.50R15. The Base sub-model uses 235/75R15, while the S and w/Snow Pkg. sub-models can use either 235/75R15 or 31X10.50R15 depending on the truck's setup.

That means the right starting point is the exact sub-model and the wheels currently on the truck. A W150 that left the factory in one configuration may now have different wheels or a different tire package, so the size on the sidewall and the actual rim diameter should be checked before choosing a replacement.

Both tire sizes used on the 1990 Dodge Trucks W150 are built for 15-inch rims. The 235/75R15 size and the 31X10.50R15 size each share that same wheel diameter, even though the tires differ noticeably in overall profile and section width.

A matching 15-inch diameter does not mean every tire suits every wheel equally. Rim width still matters, especially when moving between a metric 235/75R15 and a wider flotation-style 31X10.50R15, so the actual wheel width and the tire's intended rim-width range should be compared before making a change.

No. The 1990 Dodge Trucks W150 Base uses 235/75R15, while the W150 S and W150 w/Snow Pkg. can use either 235/75R15 or 31X10.50R15. All of those fitments are radial and use 15-inch rims, but the size range is not identical across every sub-model.

That distinction matters because a larger 31X10.50R15 changes the truck's tire profile compared with a 235/75R15. Before selecting tires, confirm the exact sub-model, then verify what wheels are currently installed so the replacement matches the truck's actual configuration rather than assuming all W150s were equipped alike.

Start with the basics: 235/75R15 is a primary radial size for the 1990 Dodge Trucks W150, and it appears across all three covered sub-models. From there, the meaningful differences are brand, tire series, sidewall style, rim-width compatibility, and load figure at the stated inflation pressure.

That gives this size a broad range of personalities, from BFGoodrich All-Terrain T/A KO2 with RWL styling to whitewall radials from American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. The best match depends on whether the truck is being kept utility-oriented, dressed in a more traditional style, or restored with a period-inspired appearance.

Sidewall choices for the 1990 Dodge Trucks W150 include raised white letter, narrow whitewall, and wide whitewall styles. In 235/75R15, those appearance options are spread across several brands and tire series, while 31X10.50R15 is available in a raised white letter all-terrain layout.

That range lets the same truck lean in different directions visually. Raised white letters suit a more rugged late-1980s and early-1990s 4x4 look, while narrow or wide whitewalls create a more custom or restoration-oriented presentation. The right choice depends on the truck's intended character and the exact size that belongs on that sub-model.

The 1990 Dodge Trucks W150 has available tires from BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. Most of that variety appears in the 235/75R15 size, while 31X10.50R15 is represented by a BFGoodrich All-Terrain T/A KO2 application.

Brand choice should be considered alongside construction, sidewall style, and tire series rather than by name alone. A W150 owner choosing between brands is really deciding how the truck should look and be used, whether that means an all-terrain RWL style or a whitewall radial that gives a more traditional presentation on 15-inch wheels.

A period-style 1990 Dodge Trucks W150 usually starts with the correct primary size for the truck's sub-model and wheel setup. For many trucks that means 235/75R15, which is available in several radial series and sidewall treatments that can support a stock-looking or custom-era presentation.

Appearance choice matters as much as size on a truck from this era. Raised white letters give the W150 a stronger 4x4 personality, while narrow or wide whitewalls create a more distinctive restoration-oriented look. When exact originality matters, compare the tire choice with vehicle-specific photos, build documentation, or marque references before settling on a final style.

On the 1990 Dodge Trucks W150, the primary fitments are radial, so construction itself is not a bias-ply-versus-radial styling question. The more visible appearance difference comes from the tire format and sidewall treatment, especially when comparing a 235/75R15 whitewall radial with a 31X10.50R15 raised white letter all-terrain tire.

That means a restored W150 can look substantially different even while staying within correct-size radial territory. A metric radial with whitewall styling supports a cleaner, more traditional presentation, while a flotation-style all-terrain makes the truck appear more aggressive and utility-focused. The choice should match the truck's intended era feel and finished stance.

Yes. Modifications can change tire fitment on a 1990 Dodge Trucks W150 even when the tire size itself is commonly used on the truck. Aftermarket wheels, different wheel widths, suspension changes, lift or lowering work, and body alterations can all affect how a 235/75R15 or 31X10.50R15 sits and clears.

That is especially important on a vintage 4x4 that may have changed hands several times. Before replacing tires, inspect the actual wheel diameter and width, then check steering clearance, fender clearance, and suspension condition. Those steps help confirm whether the truck still matches its expected setup or needs a more careful fitment review.

Before road use, inspect wheel condition, lug hardware, valve stems, and the truck's general suspension and steering components. It also makes sense to confirm that all four tires are the intended size, properly inflated, and free from shipping damage, mounting damage, or any obvious irregularity once installed.

A 1990 W150 may spend long periods parked, so the rest of the truck deserves attention too. Check for alignment issues, worn shocks, loose steering parts, brake condition, and any rubbing during full-lock turns or suspension movement. A fresh set of tires performs best when the rest of the chassis is ready for regular road use.

Tires on a collector 1990 Dodge Trucks W150 should be checked regularly for pressure loss, uneven tread wear, sidewall cracking, bulges, cuts, and signs of flat spotting from long storage. Even a truck that sees limited mileage needs periodic inspection because age and environment can affect tires as much as road use.

Good storage habits help preserve both 235/75R15 and 31X10.50R15 radials. Keep the truck away from prolonged sunlight, excess heat, moisture, and ozone sources such as electric motors, and move it occasionally if it sits for extended periods. Before a longer drive, recheck pressure, overall condition, and clearances rather than relying on appearance alone.
