1988 Dodge Trucks W100 Tires

The 1988 Dodge Trucks W100 uses two primary tire sizes: 235/75R15 and 31X10.50R15. Both are radial tires built for 15-inch rims, so the truck does not rely on a bias-ply fitment in this application.

The key is confirming which setup your truck actually has before choosing a replacement. A W100 wearing 235/75R15 and a W100 wearing 31X10.50R15 may both be correct within this fitment range, but they differ in overall stance, section width, and wheel-width needs. Checking the existing wheel size, current tire size, and clearance around the suspension and fenders will point you to the right choice.

The applicable tire sizes for the 1988 Dodge Trucks W100 both use a 15-inch rim diameter. That applies to both 235/75R15 and 31X10.50R15, so rim diameter stays consistent even though the tire sizes themselves are different.

Rim diameter is only part of the fitment picture, especially on a truck that may have changed wheels over time. Width also matters, because the available 235/75R15 and 31X10.50R15 tires call for different wheel-width ranges depending on the product. Before replacing tires, verify the wheel’s stamped diameter and width so the tire size and the wheel specification work together rather than simply sharing the same 15-inch diameter.

31X10.50R15 is a flotation-style radial truck size. The 31 refers to approximate overall tire diameter in inches, 10.50 is the nominal section width in inches, R indicates radial construction, and 15 is the rim diameter.

That sizing format reads differently from a metric size such as 235/75R15, so it helps to understand what it signals on a W100. A 31X10.50R15 generally points to a taller, broader truck presentation and often pairs naturally with an all-terrain look. Because flotation sizes can change stance and wheel-width needs, it is wise to compare the truck’s current wheels and check steering, fender, and suspension clearance before making the switch.

Start with the correct primary size for the truck’s current setup: 235/75R15 or 31X10.50R15, both on 15-inch rims. From there, compare construction, wheel-width compatibility, sidewall style, series, and load figures where they matter for how the truck is used.

A 235/75R15 opens up a wide range of choices, including raised white letter, narrow whitewall, and wide whitewall options, while 31X10.50R15 leans toward a truck-focused all-terrain presentation. The right tire depends on whether the goal is a more stock-style road look, a restoration-oriented whitewall appearance, or a functional light-truck stance. Matching the tire to the wheel and to the truck’s actual use matters more than choosing by appearance alone.

Sidewall choices for the 1988 Dodge Trucks W100 include raised white letter, narrow whitewall, and wide whitewall treatments. The broadest variety appears in 235/75R15, while 31X10.50R15 is available here as a raised white letter all-terrain tire.

That range gives the W100 very different visual personalities depending on the tire selected. Raised white letter styling suits a more truck-oriented or late-1980s performance-inspired look, while narrow and wide whitewalls create a more customized or restoration-minded presentation. Since sidewall style does not change the need for correct sizing, choose the look after confirming the proper tire size and wheel-width range for the truck’s actual setup.

Tires for the 1988 Dodge Trucks W100 are available from BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. Brand choice is especially broad in 235/75R15, while 31X10.50R15 is represented here by BFGoodrich.

The most useful way to compare brands on this truck is by the type of tire each one offers rather than by name alone. Some options emphasize all-terrain, raised white letter styling, while others focus on classic radial whitewall presentation in narrow or wide formats. Once the correct size is confirmed, compare sidewall treatment, tire series, wheel-width specification, and load figures to find the option that suits the truck’s appearance and use.

A period-style choice for a 1988 Dodge Trucks W100 starts with the truck’s actual size setup, either 235/75R15 or 31X10.50R15. From there, the decision usually comes down to whether the truck should present as a more stock-style late-1980s pickup, a customized whitewall truck, or a more rugged raised-white-letter 4x4.

The 235/75R15 size offers the widest appearance range, including narrow and wide whitewalls as well as raised white letter options, so it gives the most flexibility for visual tuning. The 31X10.50R15 size creates a taller, more truck-forward stance with all-terrain character. When exact originality matters, compare the tire choice against the truck’s existing wheel setup and any vehicle-specific historical references tied to that particular build.

On the 1988 Dodge Trucks W100, both primary fitments are radial, so the appearance differences come more from tire size, sidewall treatment, and tread character than from choosing between bias-ply and radial construction. A 235/75R15 can look restrained or dressed up depending on sidewall style, while 31X10.50R15 gives the truck a taller and broader visual stance.

That makes details such as whitewall width, raised white letter styling, and overall tire profile especially important on a restoration-oriented truck. A wide whitewall can push the truck toward a custom presentation, while an all-terrain raised white letter tire can emphasize its four-wheel-drive personality. Appearance should still be balanced against wheel compatibility and the truck’s intended use so the finished setup looks right and functions properly.

Yes. Modifications can change how either 235/75R15 or 31X10.50R15 fits on a 1988 Dodge Trucks W100, even though both sizes use a 15-inch rim diameter. Aftermarket wheels, different wheel widths, suspension lifts, lowering changes, or body alterations can all influence clearance and stance.

A truck that has been altered may need more than a simple size match before replacement tires are chosen. Wheel width should be confirmed against the tire’s intended range, and the owner should inspect steering travel, fender clearance, and suspension space with the truck at normal ride height. Those checks are especially important when moving toward a wider or taller truck-style tire rather than staying with the current setup.

Before road use, inspect the wheels for correct diameter and width, make sure the tires are inflated properly, and look over valve stems, lug hardware, and overall tire seating on the rim. It also helps to turn the steering lock to lock and watch for contact points around the suspension and fenders.

A collector or lightly used truck can have issues beyond the tires themselves, so a broader check is worthwhile. Examine shocks, steering components, brake condition, and wheel-bearing play, especially if the truck has sat for long periods. After the first few drives, recheck air pressure and look for uneven wear or rubbing marks, since those are often the earliest signs that a tire and wheel combination needs closer attention.

Tires on a collector 1988 Dodge Trucks W100 should be maintained with regular pressure checks, visual inspections, and attention to aging even when the truck is driven only occasionally. Look for cracking, bulges, cuts, flat spotting, uneven wear, and gradual air loss, especially after storage.

Storage conditions matter almost as much as mileage on an older truck. Keeping the W100 away from prolonged sunlight, heat, standing moisture, and ozone sources helps preserve the rubber, while moving the truck periodically can reduce flat spotting. It is also smart to inspect the wheels and suspension at the same time, because tire wear patterns often reveal alignment, steering, or ride-height issues that should be corrected before longer road use.
