The 1980 Jeep Trucks Cherokee sits in the era when full-size Jeeps balanced utility, family use, and off-road credibility in one square-shouldered package. By this point, the Cherokee had become a familiar choice for owners who wanted truck-based toughness with enclosed SUV practicality. Tire fitment on the 1980 Jeep Trucks Cherokee can center on 225/75R15 radial, L78-15 bias-ply, or 10-15 bias-ply sizing, depending on the sub-model and setup. That creates meaningful choice between traditional bias-ply presentation, whitewall variations, truck-oriented bias-ply designs, and a modern radial path. The right selection starts with identifying the exact Cherokee version and staying mindful of wheel width, appearance goals, and intended road use.
Which Tire Size Is Right for The 1980 Jeep Trucks Cherokee
Three primary tire sizes apply to the 1980 Jeep Trucks Cherokee, and the correct one depends on the exact sub-model. All three use a 15-inch rim, but the fitment mix includes both radial and bias-ply construction, so the first step is confirming whether the vehicle is a Base or Wide Track and then matching the tire to the wheel and the type of driving or restoration outcome you want.
225/75R15 is a metric radial size in which 225 identifies the nominal section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and 15 is the rim diameter in inches. On the 1980 Jeep Trucks Cherokee, this size represents a modern radial-style fitment for the Base sub-model. Available choices include BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar, with narrow and wide whitewall treatments depending on the look you want. It is a useful choice for owners seeking a 15-inch radial tire with more modern sizing language and several appearance options.
L78-15 is a vintage alphanumeric bias-ply size in which the letter marks the tire's size class, the 78 identifies its profile family, and the 15 is the rim diameter. For the 1980 Jeep Trucks Cherokee, it serves as a traditional 15-inch bias-ply fitment used across more than one sub-model. Product choices range from blackwall truck-style designs to wide whitewall, narrow whitewall, and dual-white-stripe versions from brands such as Coker Classic, BFGoodrich, and STA. This size is the one to evaluate when traditional construction and period-style appearance matter more than switching to a modern metric radial.
10-15 is a numeric bias-ply size, with the leading number expressing the nominal section width in inches and the final number indicating a 15-inch rim. On the 1980 Jeep Trucks Cherokee, this size is tied to the Wide Track sub-model and points to a more specialized bias-ply fitment than the metric radial option. Its format is older and more truck-oriented in character, so buyers should approach it by confirming the exact wheel setup and how closely the vehicle remains to its intended configuration. This size becomes especially important when preserving the stance and fitment character of a Wide Track Cherokee.
Sub-model fitment matters on the 1980 Jeep Trucks Cherokee because the Base and Wide Track versions do not share the same complete tire-size menu. Both use 15-inch wheels, but the construction and sizing path can change with the specific Cherokee configuration, so identifying the sub-model is the key first step.

1980 Jeep Trucks Cherokee Base
The 1980 Jeep Trucks Cherokee Base uses either 225/75R15 radial or L78-15 bias-ply sizing on a 15-inch rim. That gives Base owners a choice between a modern metric radial format and a traditional alphanumeric bias-ply format, making construction, appearance, and wheel compatibility the main selection points.
The 1980 Jeep Trucks Cherokee Wide Track uses bias-ply sizing, with 10-15 and L78-15 both associated with this sub-model. That makes wheel confirmation especially important, since the buyer decision centers less on radial conversion and more on matching the Cherokee's existing 15-inch wheel setup and intended look.
Bias-Ply to Radial Tire Conversion for the 1980 Jeep Trucks Cherokee
For L78-15, four radial-equivalent options are available. 235R15 is the 80-series metric radial equivalent, P235/75R15 is the P-metric 75-series radial equivalent, P255/70R15 is the P-metric 70-series radial equivalent, and 820R15 is the bias-look radial equivalent. Together, these choices span conventional metric radial sizing, P-metric alternatives with different profile families, and a radial option that keeps a more traditional visual character. A 6-8 inch rim-width range is associated with these equivalents, and wheel width, overall dimensions, and vehicle clearance should still be checked before changing formats.

These FAQs focus on the exact tire sizes used on the 1980 Jeep Trucks Cherokee, how Base and Wide Track fitment differs, what the L78-15 radial equivalents mean, and what to inspect before putting a collector-era Jeep back on the road.
Tire Size & Fitment
What tire size fits a 1980 Jeep Trucks Cherokee?
The 1980 Jeep Trucks Cherokee uses three primary tire sizes: 225/75R15 radial, L78-15 bias-ply, and 10-15 bias-ply. The right one depends on the sub-model, because the Base uses 225/75R15 or L78-15, while the Wide Track uses 10-15 or L78-15.
That means the first fitment question is not simply rim diameter, since all of these sizes use 15-inch wheels. The practical step is confirming whether the Cherokee is a Base or Wide Track and then checking the actual wheel width and current setup before choosing between metric radial sizing and older bias-ply formats.
What size rim does a 1980 Jeep Trucks Cherokee use?
The tire sizes associated with the 1980 Jeep Trucks Cherokee all use a 15-inch rim diameter. That includes 225/75R15, L78-15, and 10-15, so the common wheel diameter across the covered fitments is 15 inches.
Rim diameter alone does not settle the whole fitment question, because wheel width still matters when comparing radial and bias-ply choices. A Cherokee that has been changed over to different wheels, or one wearing a different tire than expected, should have the wheel measured and the sidewall size checked before any replacement decision is made.
Why does the 1980 Jeep Trucks Cherokee have more than one tire size?
More than one tire size appears on the 1980 Jeep Trucks Cherokee because fitment varies by sub-model and construction type. The Base can use a modern-style 225/75R15 radial or an L78-15 bias-ply, while the Wide Track uses bias-ply sizing with 10-15 and L78-15.
That difference matters because a buyer may be choosing between two sizing systems as well as two tire constructions. Instead of assuming all 1980 Cherokee models use the same tire, identify the sub-model first, then compare the existing wheels and the look and driving character you want from the finished setup.
Bias-Ply & Radial Options
Is L78-15 a bias-ply or radial tire for the 1980 Jeep Trucks Cherokee?
L78-15 is a bias-ply tire size on the 1980 Jeep Trucks Cherokee. It uses the vintage alphanumeric sizing format rather than a modern metric radial format, and it appears across both Cherokee sub-model coverage on a 15-inch rim.
That makes L78-15 the traditional-construction choice for owners who want an older tire format and period-style presentation. A buyer considering an L78-15 should compare wheel width, sidewall style, and whether the Jeep is being kept close to a restoration-oriented look or moved toward a radial alternative.
What radial tire sizes are equivalent to L78-15?
Radial equivalents for L78-15 include 235R15 as the 80-series metric radial option, P235/75R15 as the 75-series P-metric option, P255/70R15 as the 70-series P-metric option, and 820R15 as the bias-look radial equivalent. Each keeps the discussion on a 15-inch wheel while changing the sizing format.
Those options are useful comparison points, but they should not be treated as automatic substitutions. The associated rim-width range is 6-8 inches, and the Cherokee's wheel width, tire clearance, and overall setup still need to be checked before moving from an L78-15 bias-ply fitment into any of these radial formats.
What should I check before converting my 1980 Jeep Trucks Cherokee from bias-ply to radial tires?
Start by confirming the original bias-ply size on the Jeep and then matching it to an actual radial equivalent that applies to that size. For an L78-15 Cherokee fitment, the available radial-equivalent choices are 235R15, P235/75R15, P255/70R15, and 820R15, all still based around a 15-inch rim.
After that, inspect wheel width, tire-to-fender clearance, and any suspension or wheel changes made over the years. Construction changes can also alter the visual character of the vehicle, so owners balancing drivability with period-style appearance should compare the radial format carefully before settling on a final replacement size.
Choosing the Right Tire
What should I consider when choosing a tire for a 1980 Jeep Trucks Cherokee?
Begin with the exact tire size that matches the sub-model and wheel setup, because the 1980 Jeep Trucks Cherokee spans 225/75R15 radial plus L78-15 and 10-15 bias-ply sizing. Construction type is the next major decision, especially if the goal is to keep a traditional look or move toward a modern radial format.
Once the size is settled, compare sidewall treatment, tire series, rim-width compatibility, and load figures where they are relevant to the Jeep's intended use. A Base Cherokee owner may be weighing radial versus bias-ply, while a Wide Track owner may be focused more on selecting the right bias-ply format for the existing wheels.
What sidewall styles are available for 1980 Jeep Trucks Cherokee tires?
Sidewall choices for 1980 Jeep Trucks Cherokee tires include blackwall, narrow whitewall, wide whitewall, and dual-white-stripe styles, depending on the tire size and product selected. The 225/75R15 radial assortment focuses on whitewall options, while L78-15 includes blackwall truck-style choices as well as several whitewall presentations.
That range gives the Cherokee owner room to shape the finished appearance without changing the basic tire size. A more utility-oriented truck look may point toward blackwall bias-ply choices, while restoration-minded or more dressed-up presentation often leads buyers toward one of the narrow or wide whitewall alternatives.
What brands offer tires for the 1980 Jeep Trucks Cherokee?
Tire options for the 1980 Jeep Trucks Cherokee come from BFGoodrich, Coker Classic, American Classic, Maxxis, Travelstar, and STA. Brand availability depends on the size, with 225/75R15 covering several radial brands and L78-15 extending into both traditional passenger-style and truck-oriented bias-ply offerings.
Brand choice should be considered alongside the actual tire series, sidewall style, and construction type rather than by name alone. One Cherokee owner may be looking for a whitewall radial for a Base model, while another may need an L78-15 blackwall or truck-pattern bias-ply that better suits the Jeep's stance and use.
Restoration & Appearance
Which tire should I choose for a period-style 1980 Jeep Trucks Cherokee?
A period-style 1980 Jeep Trucks Cherokee usually starts with the size and construction that match the vehicle's actual sub-model and wheel setup, which often means looking closely at L78-15 or 10-15 bias-ply fitments. Those older sizing formats preserve more of the traditional visual character than a modern metric radial presentation.
The right appearance still depends on how the Cherokee is being restored and how exact the owner wants to be. For a more historically guided result, compare the current wheels and consult Jeep-specific restoration references before choosing among blackwall, whitewall, or truck-oriented tire styles in the correct size.
How does tire construction affect the appearance of a restored 1980 Jeep Trucks Cherokee?
Tire construction changes more than road feel on a restored 1980 Jeep Trucks Cherokee; it also changes how the vehicle sits visually. A bias-ply size such as L78-15 presents in a more traditional format, while a 225/75R15 radial introduces modern metric sizing language and a different visual impression on the same 15-inch wheel diameter.
That is why restoration-minded buyers often decide on construction before narrowing down sidewall details. A Jeep intended to keep a more vintage truck character may lean toward bias-ply, while one aimed at regular road use may explore radial options, including an L78-15 bias-look radial equivalent where that visual balance matters.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1980 Jeep Trucks Cherokee?
Yes, modifications can affect tire fitment on a 1980 Jeep Trucks Cherokee even when the tire size itself is correct on paper. Changes to wheel width, aftermarket wheels, suspension height, steering components, or body clearance can all influence how a 15-inch tire sits and moves through its full range of travel.
That matters even more on a Cherokee with multiple possible sizes and both bias-ply and radial paths available. A Jeep that has been lifted, lowered, or fitted with different wheels should have the wheel dimensions confirmed and the tire checked for clearance at the fender, suspension, and steering positions before finalizing a replacement.
What should I inspect before driving a 1980 Jeep Trucks Cherokee on new tires?
Before driving a 1980 Jeep Trucks Cherokee on new tires, inspect the wheels for correct diameter and sound condition, confirm the tires are inflated properly, and check for clearance around the fenders, suspension, and steering components. Lug hardware, valve stems, and overall wheel mounting should also be reviewed carefully.
A collector-era Jeep benefits from a broader walkaround as well, especially if it has been parked for long periods. Look over the suspension, steering response, brake feel, and any sign of rubbing during low-speed turns so the new tires are being evaluated as part of the whole vehicle rather than in isolation.
How should tires on a collector 1980 Jeep Trucks Cherokee be maintained?
Tires on a collector 1980 Jeep Trucks Cherokee should be maintained with regular pressure checks, visual inspection, and attention to age and storage conditions. Even a Jeep that sees limited mileage can develop cracking, flat spotting, air loss, or sidewall damage if it sits too long or is stored in harsh heat and sunlight.
Routine checks are especially important with older-style bias-ply sizes and low-use collector vehicles. Keep the Cherokee on clean, dry surfaces when possible, inspect tread and sidewalls before each outing, and recheck the tires after storage periods so small problems are caught before they turn into road-use or fitment issues.
