The 1987 Toyota Trucks Land Cruiser comes from the later era of Toyota’s long-running four-wheel-drive workhorse, a vehicle valued for its durability, trail capability, and honest utility. By this point, the Land Cruiser had earned a strong reputation with owners who still expect real-world use from a vintage SUV. This application uses an HR78-15 radial tire on a 15-inch rim, giving the page a straightforward fitment starting point. The main decision is less about multiple sizes and more about choosing the right radial in the correct vintage alphanumeric format. That matters whether the goal is a restoration-minded look, dependable road use, or careful preservation of the truck’s original character.
Which Tire Size Is Right for The 1987 Toyota Trucks Land Cruiser
The 1987 Toyota Trucks Land Cruiser uses one primary tire size: HR78-15. It is a radial tire size for a 15-inch rim, and it is shared across the covered Above 50 mph and Below 50 mph Land Cruiser sub-models. That makes fitment relatively simple, so the real choice comes down to selecting the right tire style and confirming that the wheels on the truck still match the original diameter and width requirements.
HR78-15 is a vintage alphanumeric radial size in which the letter designates the tire’s size class, the R identifies radial construction, the 78 refers to the profile family, and the 15 indicates the rim diameter in inches. On a 1987 Toyota Trucks Land Cruiser, this keeps the fitment in the correct period-style radial format rather than an older numeric bias-ply pattern. Buyers looking at this size are usually balancing authentic visual character with practical road use. The important step is confirming that the truck still carries the proper 15-inch wheel setup, especially if wheels or suspension have been changed over the years.
Fitment is straightforward across the covered 1987 Toyota Trucks Land Cruiser sub-models because both use the same HR78-15 radial size. Checking the exact sub-model still helps confirm that the tire selection matches the vehicle’s intended road-speed classification and present wheel setup.

1987 Toyota Trucks Land Cruiser (Above 50 mph)
The 1987 Toyota Trucks Land Cruiser (Above 50 mph) uses the same HR78-15 radial fitment as the other covered configuration. That keeps tire selection centered on choosing the right period-style radial and verifying that the vehicle still has the correct 15-inch wheel arrangement.
The 1987 Toyota Trucks Land Cruiser (Below 50 mph) also uses the HR78-15 radial size, so there is no separate primary tire size to sort out. The main focus is selecting a suitable radial in that vintage alphanumeric format and checking the actual wheels on the truck before installation.
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.
Frequently Asked Questions
Common questions for the 1987 Toyota Trucks Land Cruiser usually center on the HR78-15 tire size, 15-inch rim fitment, vintage radial sizing, and what to inspect before putting a classic four-wheel-drive truck back on the road.
Tire Size & Fitment
What tire size fits a 1987 Toyota Trucks Land Cruiser?
The 1987 Toyota Trucks Land Cruiser uses HR78-15 tires. This is a radial tire size in a vintage alphanumeric format, and it is the primary fitment for both the Above 50 mph and Below 50 mph covered sub-models.
That makes size selection simpler than on vehicles with multiple factory fitments, but the wheel setup still needs to be confirmed before ordering tires. A Land Cruiser that has been modified over the years may no longer have its original wheel diameter or width, so checking the actual rim on the truck is still an important step.
What size rim does a 1987 Toyota Trucks Land Cruiser use?
The 1987 Toyota Trucks Land Cruiser tire fitment is based on a 15-inch rim. The HR78-15 size is built around that wheel diameter, so the tire and wheel need to match at the 15-inch bead seat.
Rim diameter is the first thing to verify if the truck has aftermarket wheels or a long history of service changes. Even when the tire currently on the vehicle looks close in height or width, a different wheel diameter changes the fitment entirely, so the sidewall marking and the wheel itself should both be checked.
Do all 1987 Toyota Trucks Land Cruiser sub-models use the same tire size?
Yes. The covered 1987 Toyota Trucks Land Cruiser sub-models, including the Above 50 mph and Below 50 mph versions, both use the same HR78-15 radial tire size. There is no separate primary size to sort out between those two fitment categories.
That consistency helps narrow the decision to tire type and wheel confirmation rather than searching among several sizes. It is still wise to identify the exact truck configuration and inspect the current wheel setup, especially on older Land Cruisers that may have been fitted with replacement wheels, suspension changes, or off-road oriented modifications.
Choosing the Right Tire
What should I consider when choosing a HR78-15 tire for a 1987 Toyota Trucks Land Cruiser?
Start with the basics: the 1987 Toyota Trucks Land Cruiser uses an HR78-15 radial on a 15-inch rim, so the tire needs to match that sizing format and wheel diameter. Since there is one primary size, the main decision is choosing a tire that suits how the truck will be used and how period-correct you want it to look.
A Land Cruiser kept for shows or preservation may call for a different visual approach than one used regularly on the road. Wheel width, overall vehicle condition, and any suspension or wheel changes should also be reviewed so the selected HR78-15 works with the truck’s current setup rather than only its original specification.
How do I choose between available HR78-15 tires for a 1987 Toyota Trucks Land Cruiser?
Choosing among HR78-15 tires for a 1987 Toyota Trucks Land Cruiser usually comes down to construction style, overall appearance, and how closely the tire suits the truck’s intended role. Because the size itself is fixed, the comparison is less about fitment categories and more about selecting the right vintage-style radial presentation.
A truck restored for period character may lead you toward one visual style, while a vehicle driven more often may push the decision toward a different balance of appearance and use. It also helps to compare wheel compatibility carefully, since an older Land Cruiser may no longer be riding on the exact wheels it originally used.
What does HR78-15 mean on a 1987 Toyota Trucks Land Cruiser?
HR78-15 is a vintage alphanumeric radial tire size. The letter indicates the tire’s general size class, the R marks it as a radial, the 78 refers to the profile family, and the 15 is the rim diameter in inches used on the 1987 Toyota Trucks Land Cruiser.
This format matters because it differs from modern metric sizing, and it helps preserve the right era-appropriate look for the vehicle. Anyone replacing older tires should read the sidewall carefully and compare it to the actual wheel on the truck, since a Land Cruiser with later wheel changes may require a different fitment path.
Restoration & Appearance
Which tire should I choose for a period-style 1987 Toyota Trucks Land Cruiser?
For a period-style 1987 Toyota Trucks Land Cruiser, the starting point is staying with the primary HR78-15 radial size. That preserves the correct vintage alphanumeric sizing format for the vehicle and keeps the tire choice aligned with the way this Land Cruiser was fitted in its model year.
From there, the right choice depends on whether the truck is being preserved as a restoration-oriented vehicle or used more regularly on the road. Appearance, sidewall presentation, and wheel compatibility all matter, and owners pursuing exact historical accuracy should compare their tire choice with marque-specific restoration references for the particular truck.
Does correct tire fitment matter for a 1987 Toyota Trucks Land Cruiser restoration?
Yes, correct tire fitment plays a major role in the overall look and stance of a restored 1987 Toyota Trucks Land Cruiser. Using the proper HR78-15 radial size helps maintain the vehicle’s period character and avoids a mismatched appearance that can come from substituting a visibly modern size without careful comparison.
Fitment also affects practical details such as wheel compatibility and clearance, which matter even on a restoration that is driven only occasionally. A Land Cruiser that has changed hands several times may have replacement wheels or suspension parts, so the restoration process should include a full check of the actual wheel and tire setup on the truck.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1987 Toyota Trucks Land Cruiser?
Yes. Modifications can change how an HR78-15 tire works on a 1987 Toyota Trucks Land Cruiser, even when that is the correct primary size. Aftermarket wheels, altered wheel width, suspension lifts, worn springs, or body changes can all affect clearance and how the tire sits on the vehicle.
That is why an older Land Cruiser should be inspected as it sits today, not only by model-year specification. Turning clearance, fender clearance, and wheel diameter should all be checked before new tires are installed, especially if the truck has seen off-road use or has been updated over time for utility or appearance.
What should I inspect before driving a 1987 Toyota Trucks Land Cruiser on new tires?
Before putting a 1987 Toyota Trucks Land Cruiser into service on new tires, inspect the wheels for damage, confirm the 15-inch rim size, and make sure the tires are mounted and inflated correctly for the application. It is also wise to look over the steering and suspension for looseness or wear that could affect tire behavior.
A road test is best started with basic checks for rubbing, uneven stance, vibration, and any sign of interference at full steering lock. Classic four-wheel-drive vehicles often spend long periods parked, so wheel bearings, brakes, and old suspension components deserve the same attention as the new tires before regular driving begins.
How should HR78-15 tires on a collector 1987 Toyota Trucks Land Cruiser be maintained?
HR78-15 tires on a collector 1987 Toyota Trucks Land Cruiser should be inspected regularly for air loss, tread wear, sidewall cracking, cuts, and bulges. Collector vehicles often age their tires through time and storage as much as mileage, so condition matters just as much as how much tread remains.
Proper inflation, clean storage conditions, and protection from prolonged sunlight, heat, and ozone sources help preserve the tires between drives. It also helps to move the truck periodically or avoid letting it sit in one position for long stretches, since long-term storage can stress both the tires and the suspension.
