The 1994 Isuzu Trucks Pickup sits in the compact-truck era when simple, durable work pickups still came in clearly defined two-wheel-drive and four-wheel-drive configurations. That matters with tires, because this truck uses three different radial sizes depending on the exact setup: 195/75R14, 225/75R15, or 31X10.50R15. The decision starts with identifying whether the truck is an S 4x2 or S 4x4 and then confirming whether it is on 14-inch or 15-inch wheels. From there, the available choices range from traditional whitewall radial options to an all-terrain raised white letter tire, depending on whether the goal is stock-style appearance, light-duty road use, or a more truck-oriented stance.
Which Tire Size Is Right for The 1994 Isuzu Trucks Pickup
Three tire sizes apply to the 1994 Isuzu Trucks Pickup, and they do not serve the same configurations. The first step is confirming the exact sub-model, because the S 4x2 uses a different size than the S 4x4, and wheel diameter also changes between 14-inch and 15-inch applications. Once that is settled, the real choice becomes selecting the right radial style, appearance, and intended use within the correct size.
195/75R14 is a metric radial size in which 195 identifies nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 14 is the rim diameter in inches. On this Isuzu pickup, it serves the 4x2 applications and keeps the fitment centered on a passenger-style road radial. Available choices include Coker Classic, Tornel, Maxxis, and Travelstar options, with wide whitewall and narrow whitewall treatments across several series. It is the size to evaluate when the truck retains its 14-inch 4x2 wheel setup and the goal is road use with a traditional sidewall presentation.
225/75R15 is a metric radial size with a 225-millimeter nominal section width, a 75-series profile, radial construction, and a 15-inch rim diameter. On the 1994 Isuzu Trucks Pickup, this size belongs to 4x4 applications and represents a more substantial road-oriented fitment than the 14-inch 4x2 tire. Product choices include BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar, with both wide whitewall and narrow whitewall options in several radial series. This is the size to consider when the truck is a 4x4 on 15-inch wheels and the goal is a conventional highway-style radial rather than a flotation all-terrain tire.
31X10.50R15 uses a flotation-style light truck format in which 31 refers to approximate overall tire diameter in inches, 10.50 is nominal section width, R indicates radial construction, and 15 is the wheel diameter. For this Isuzu pickup, it appears on 4x4 applications and shifts the fitment toward a taller, more truck-oriented tire choice. The available option in this size is a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls, giving it a distinctly off-road-inspired look compared with the whitewall 225/75R15 selections. It deserves a closer look when the truck is already set up around a 31-inch radial and wheel width and clearance have been verified.
Sub-model fitment matters on the 1994 Isuzu Trucks Pickup because tire size changes with drivetrain and wheel package. The S 4x2 models stay with a 14-inch radial, while the S 4x4 models use 15-inch radial sizes, so identifying the exact truck configuration comes before choosing a tire.

1994 Isuzu Trucks Pickup S 4x2
The 1994 Isuzu Trucks Pickup S 4x2 uses the 195/75R14 radial size. Tire selection here is mainly about choosing the right road-going radial style and sidewall appearance while keeping the truck on its correct 14-inch wheel setup.
The 1994 Isuzu Trucks Pickup S 4x2 w/aluminum wheels also uses the 195/75R14 radial size. That keeps fitment straightforward, with the main decision centered on which whitewall style or radial series best matches the truck's intended look and use.
The 1994 Isuzu Trucks Pickup S 4x4 uses 15-inch radial tire fitments, with both 225/75R15 and 31X10.50R15 associated with this sub-model. The practical choice is whether the truck is being kept on a more standard road-style 15-inch radial or a taller flotation-size all-terrain setup.
The 1994 Isuzu Trucks Pickup S 4x4 w/aluminum wheels follows the same 15-inch radial fitment pattern, using 225/75R15 or 31X10.50R15. Picking the right tire starts with confirming the wheel and current setup so the truck's stance, clearance, and intended use all stay aligned.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Owners of a 1994 Isuzu Trucks Pickup usually need to sort out sub-model fitment first, then compare wheel diameter, radial size, sidewall style, and intended use. These FAQs focus on those practical decisions, along with maintenance and road-readiness checks.
Tire Size & Fitment
What tire size fits a 1994 Isuzu Trucks Pickup?
A 1994 Isuzu Trucks Pickup can use 195/75R14, 225/75R15, or 31X10.50R15, depending on the sub-model and wheel setup. The S 4x2 configurations use 195/75R14, while the S 4x4 configurations use 225/75R15 or 31X10.50R15. All of these are radial tire fitments.
The key step is matching the tire to the exact truck rather than the model name alone. A 4x2 truck on 14-inch wheels needs a different tire than a 4x4 on 15-inch wheels, and a 31-inch flotation tire should not be treated as interchangeable with a standard metric 15-inch size without checking the wheel and vehicle setup carefully.
What size rim does a 1994 Isuzu Trucks Pickup use?
The 1994 Isuzu Trucks Pickup uses either a 14-inch or 15-inch rim, depending on the tire size and sub-model. The 195/75R14 fitment uses a 14-inch rim, while both 225/75R15 and 31X10.50R15 use a 15-inch rim. Rim diameter is one of the first things to confirm before selecting replacement tires.
That matters because tire sizes with different final rim numbers are not meant for the same wheel diameter. A truck wearing 15-inch tires needs a very different replacement path than one still on 14-inch wheels, so checking the current wheel size on the vehicle helps avoid choosing a tire that matches the truck model but not the actual wheel installed.
Why does the 1994 Isuzu Trucks Pickup have more than one tire size?
The 1994 Isuzu Trucks Pickup has more than one tire size because fitment varies by sub-model and drivetrain. The S 4x2 models use 195/75R14, while the S 4x4 models use 15-inch tire sizes, including 225/75R15 and 31X10.50R15. Those differences reflect distinct wheel and usage setups within the same model line.
For a buyer, that means the truck's exact configuration matters more than the year and model name by themselves. A 4x4 may be set up around a road-oriented 225/75R15 or a taller all-terrain 31X10.50R15, so the best next step is to confirm the sub-model, check the wheel diameter already on the truck, and compare the intended tire style to how the pickup will actually be used.
Choosing the Right Tire
What should I consider when choosing a tire for a 1994 Isuzu Trucks Pickup?
Start with the exact fitment: 195/75R14 for S 4x2 models, or 225/75R15 and 31X10.50R15 for S 4x4 models. All primary sizes here are radial, so the real comparison usually comes down to wheel diameter, tire format, sidewall treatment, rim-width compatibility, and whether the truck is being kept as a road-going pickup or set up with a more aggressive all-terrain stance.
Appearance and intended use should guide the final choice within the correct size. A whitewall radial gives a very different presentation than a raised white letter all-terrain, and a flotation-size 31-inch tire deserves extra attention to wheel width and clearance. Matching the tire to the truck's actual configuration will matter more than choosing by brand name alone.
What sidewall styles are available for 1994 Isuzu Trucks Pickup tires?
Sidewall choices for the 1994 Isuzu Trucks Pickup include wide whitewall, narrow whitewall, and raised white letter styles, depending on tire size. The 195/75R14 and 225/75R15 sizes are offered with whitewall variations, while the 31X10.50R15 option appears as a raised white letter all-terrain tire.
That gives the truck a broad appearance range even before brand or series differences are considered. A whitewall radial leans toward a more traditional custom or retro look, while raised white letters create a more rugged truck presentation. The best match depends on the truck's wheel setup, whether it is 4x2 or 4x4, and the kind of visual character the owner wants.
What brands offer tires for the 1994 Isuzu Trucks Pickup?
Tires for the 1994 Isuzu Trucks Pickup are available from Coker Classic, Tornel, Maxxis, Travelstar, BFGoodrich, and American Classic. Brand availability depends on the tire size, with the broadest selection appearing in 195/75R14 and 225/75R15, while the 31X10.50R15 fitment is represented by a BFGoodrich all-terrain option.
Brand name is only one part of the comparison. It helps to look at which series each brand offers, along with sidewall style, rim-width specification, and the overall character of the tire in the correct size. For this Isuzu, choosing between a whitewall road radial and a more truck-oriented all-terrain often shapes the decision as much as the brand itself.
Restoration & Appearance
Which tire should I choose for a period-style 1994 Isuzu Trucks Pickup?
A period-style choice for a 1994 Isuzu Trucks Pickup starts with the correct size for the exact sub-model, then moves to the tire's visual character. On 4x2 trucks, 195/75R14 whitewall radials can create a more traditional presentation, while 4x4 trucks on 225/75R15 can also be fitted with whitewall radial options in several series.
The right appearance depends on how the truck is being interpreted. Some owners may want a cleaner street-oriented look, while others may prefer the more rugged 31X10.50R15 raised white letter style on a 4x4. When exact originality matters, vehicle-specific historical references and marque knowledge are worth consulting before settling on a sidewall treatment.
How does tire construction affect the appearance of a restored 1994 Isuzu Trucks Pickup?
On the 1994 Isuzu Trucks Pickup, primary fitment stays within radial construction, so appearance changes come more from size and sidewall style than from switching between bias-ply and radial. A narrow or wide whitewall radial gives a noticeably different look from a raised white letter all-terrain, even when both remain within the truck's supported fitment patterns.
That means a restored or carefully presented truck should be matched to the visual era and use the owner wants to emphasize. A 4x2 with whitewalls reads differently than a 4x4 on a 31-inch all-terrain, and both can be appropriate in the right context. Size, wheel diameter, and stance all contribute to the truck's finished appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1994 Isuzu Trucks Pickup?
Yes, modifications can affect tire fitment on a 1994 Isuzu Trucks Pickup even when the tire size itself is associated with the model. Changes to wheel width, offset, suspension height, alignment, or body clearance can alter how a 195/75R14, 225/75R15, or 31X10.50R15 tire sits and behaves on the truck.
That is especially important on 4x4 applications where both a standard metric 15-inch size and a taller flotation-size tire may be used. A truck with aftermarket wheels or ride-height changes should be checked for steering clearance, fender clearance, and wheel compatibility before replacement tires are chosen simply by size code.
What should I inspect before driving a 1994 Isuzu Trucks Pickup on new tires?
Before driving a 1994 Isuzu Trucks Pickup on new tires, inspect the wheels for correct diameter and condition, confirm the lug hardware is appropriate, and make sure the tires are mounted in the proper size for the truck's exact setup. It also helps to check inflation, valve stems, and basic alignment condition before putting the truck back into regular use.
A short road test should be followed by another look for rubbing, uneven seating, vibration, or air loss. Older compact pickups are often modified or used intermittently, so suspension wear, steering play, and brake condition are worth checking at the same time. New tires perform best when the rest of the wheel and chassis system is in sound condition.
How should tires on a collector-era 1994 Isuzu Trucks Pickup be maintained?
Tires on a collector-era 1994 Isuzu Trucks Pickup should be maintained with regular pressure checks, visual inspections, and attention to age-related condition. Look for cracking, bulges, cuts, uneven tread wear, and slow air loss, especially if the truck is driven seasonally or stored for long periods rather than used as a daily driver.
Storage conditions also matter. Keeping the truck away from prolonged sunlight, moisture, and ozone sources helps preserve the tires, and moving or driving it periodically can prevent long static periods on one contact patch. Any pickup that sees occasional highway use should have its tires and wheel setup inspected before a longer drive, not just before show use.
