Ford Bronco Tires

Ford Bronco uses six sizes across the 1971 to 1979 range covered here: E78-15 from 1971 to 1977, G78-15 from 1971 to 1977, L78-15 from 1971 to 1979, 700-15 from 1973 to 1979, H78-15 from 1978 to 1979, and LR78-15 from 1978 to 1979. Every listed size uses a 15-inch rim, but the section width class, construction style, and intended use vary considerably from one size to another.

That overlap means year alone does not automatically settle the question on a Ford Bronco. Start with the year, then inspect the wheel, compare the size already on the truck, and decide whether you are preserving a period-correct bias-ply look or moving toward the later radial-style option listed for 1978 and 1979.

A 700-15 tire on a Ford Bronco uses an older numeric bias-ply sizing system. The 700 indicates a nominal 7.00-inch section width, and the 15 indicates a 15-inch wheel diameter. Within this Bronco range, 700-15 appears from 1973 through 1979 and is available in several blackwall patterns, including passenger-style and truck-service designs.

Numeric sizes can confuse buyers who are more familiar with modern metric codes, so it helps to treat 700-15 as a period truck-era size rather than trying to compare it directly to a modern light-truck metric tire. If your Ford Bronco is being restored to a work-oriented or utility look, this is one of the most visually appropriate places to begin.

A 1973 Ford Bronco has four sizes listed because that year sits in an overlap period where E78-15, G78-15, L78-15, and 700-15 were all used. Those sizes all fit 15-inch rims, so the split is not a wheel-diameter change. Instead, it points to different equipment groupings and uses within the same model year, including both passenger-style bias-ply and truck-oriented numeric choices.

For a 1973 Ford Bronco, the right approach is to identify the exact wheel width, the size previously fitted if it is known to be correct, and the look you want the truck to retain. A narrow early-style restoration, a broader street-oriented stance, and a more utility-focused setup can all push the choice toward different listed sizes.

Most Ford Bronco sizes listed here are older bias-ply designs in alphanumeric or numeric formats, and those generally call for tubes. That applies to E78-15, G78-15, L78-15, 700-15, and H78-15 when fitted in the bias-ply products shown for those sizes. LR78-15 is different because it is a bias-look radial rather than a traditional bias-ply tire.

Tube choice should follow the tire and wheel combination actually being used, not just the year of the Bronco. If you are fitting one of the traditional bias-ply sizes, plan the installation as a tube-type setup unless the individual tire and wheel combination clearly indicates otherwise, especially on a collector truck where originality and proper assembly both matter.

A 1978 Ford Bronco can use 700-15, H78-15, L78-15, or LR78-15, so the year by itself is not enough to choose correctly. All four are 15-inch sizes, but they represent different width classes and, in the case of LR78-15, a radial-style construction rather than a traditional bias-ply layout. That makes 1978 one of the most important years to verify carefully.

Begin with the size marking on the current tire if the truck has a known-correct setup, then compare wheel width and the type of restoration or road use you want. If the Bronco is being kept period-correct, a bias-ply size may be the better match visually, while LR78-15 is the size to examine if you want the later radial-format option listed for those final years.

Ford Bronco tires in this range appear in several sidewall styles, including blackwall, narrow whitewall, wide whitewall, and dual-white-stripe. The widest variety is in L78-15 and 700-15, while G78-15 and H78-15 also include blackwall and whitewall choices. LR78-15 is listed with a narrow whitewall in a bias-look radial design.

Sidewall style can change the personality of a Ford Bronco as much as the tread itself. Blackwall truck patterns suit a more utilitarian presentation, while whitewall and stripe treatments create a more period passenger-vehicle look that may fit certain custom, road-going, or era-themed restorations better than a purely work-oriented tire.

Ford Bronco tires in the listed sizes come from Coker Classic, BFGoodrich, Firestone, and STA. Brand coverage varies by size: some sizes are concentrated in one or two brands, while others such as 700-15 and L78-15 span several brands and series. The lineup includes classic passenger-style bias-ply designs, military and truck-oriented tread patterns, and one bias-look radial option.

That brand spread gives Ford Bronco owners room to choose for appearance as well as construction. A buyer restoring a stock-looking truck may lean toward a classic bias-ply line, while someone aiming for a more aggressive utility stance may focus on the STA or military-style offerings in the appropriate size.

Ford Bronco tires here span several series, including Coker Classic Bias Ply, Silvertown Classic Bias Ply, Firestone Classic Bias Ply, Firestone Classic Military, Super Traxion, Traxion, Transport Highway, Super Transport, and Wide Oval Radial. The main differences are construction approach and intended character: some are passenger-style classic bias-ply tires, some are military or truck-service bias-ply patterns, and Wide Oval Radial is a bias-look radial alternative in LR78-15.

Choosing among those series depends on how your Ford Bronco will be presented and driven. A restored street truck often looks right on a classic bias-ply series, while a utility-themed build may call for a truck tread such as Traxion or Transport Highway, and the radial-series option is the one to study if road manners matter more than strict bias-ply authenticity.

A stored Ford Bronco should be kept in a cool, dry, dark space with the tires protected from direct sunlight, electric motors, ozone sources, and petroleum contamination. Clean the tires gently, keep them inflated appropriately for storage, and if the truck will sit for long periods, move it occasionally or support it so the same section of tire does not bear the load indefinitely.

Collector trucks often spend long stretches parked, and that can age the casing even when tread still looks strong. Good storage habits help preserve both appearance and structure, especially on older-style bias-ply designs where flat spotting and sidewall stress can become noticeable sooner than many owners expect.

Tires on a Ford Bronco should be visually inspected before regular use and checked more thoroughly several times each season, even if the truck is driven only occasionally. Look for sidewall cracking, tread separation signs, punctures, air loss, irregular wear, and any change in how the Bronco tracks or steers. Collector use does not reduce the need for inspection; in many cases it increases it.

A low-mileage Ford Bronco can hide tire problems because age and storage affect rubber differently than daily driving does. Frequent inspection is especially important when using older-style bias-ply or truck-service tires, since a problem caught early is far easier to address than a failure discovered once the vehicle is already on the road.

Ford Bronco tires should be replaced when age, cracking, hardening, impact damage, persistent air loss, or structural concerns appear, even if the tread depth still looks acceptable. Tread alone is a poor guide on collector vehicles because many old tires wear slowly but deteriorate with time. A tire that still looks presentable can still be beyond its useful service life.

That point matters even more on a rarely used Ford Bronco, where elapsed time often matters more than mileage. If the truck carries older specialty tires, have them evaluated regularly by a knowledgeable tire professional and replace them when condition, age, or behavior suggests the casing is no longer trustworthy for continued road use.

Ford Bronco was fitted across this range with several period size types rather than one single tire specification. The sizes associated with these years include E78-15, G78-15, L78-15, 700-15, H78-15, and LR78-15, and the available series span classic bias-ply passenger designs, truck-oriented patterns, military-style tread, and a later radial-format offering for 1978 to 1979. That breadth shows why one answer does not cover every Bronco equally.

For an originality-focused restoration, the key is matching the exact year and the specific configuration of the Ford Bronco before choosing a tire. Period literature, surviving original examples, and marque-club knowledge are the best way to narrow the field from the broader size range shown here to the exact style that suits a particular truck.

Correct tire fitment can absolutely affect how a Ford Bronco is judged and perceived, especially on a careful restoration. Judges and knowledgeable buyers notice whether the size, sidewall treatment, tread character, and overall stance suit the year and intended presentation of the truck. A Bronco on the wrong size or the wrong visual style can look subtly off even when the installation physically fits.

That does not mean every Ford Bronco needs the same tire philosophy. A factory-style restoration, a trail-themed vintage build, and a period custom may all justify different choices, but each should still be internally consistent. Matching the tire to the truck’s era and purpose usually supports both presentation and long-term value better than choosing purely by convenience.

Ford Bronco restoration choices here include blackwall, narrow whitewall, wide whitewall, and dual-white-stripe depending on size. Blackwall is the most workmanlike and utility-oriented presentation, while whitewall and stripe treatments push the truck toward a more stylized or road-focused period appearance. The available combinations vary by size, so sidewall correctness depends on the exact tire size chosen first.

A restored Ford Bronco usually looks most convincing when the sidewall style matches the truck’s overall theme rather than competing with it. If the goal is a straightforward utility truck, blackwall generally reads most naturally, while whitewall variants can suit certain period customs or more passenger-oriented builds when supported by the rest of the restoration.

A Ford Bronco can be driven on public roads with these tires when the size, construction, wheel fit, inflation, age, and overall condition are all appropriate. The listed range includes classic bias-ply tires, truck-service tread patterns, and one bias-look radial option, and each has its own driving character. Safety depends as much on condition and suitability as on the size stamped on the sidewall.

A collector Ford Bronco should never be treated like a modern SUV simply because it wears new-looking tires. Use the tire that matches the wheel and the truck’s intended purpose, inspect it closely, and remember that older suspension design and bias-ply handling traits can require a more measured pace than many modern drivers expect.

Before driving a Ford Bronco, check tire pressure, visible sidewall condition, tread condition, valve stems, wheel attachment, and any sign of rubbing or uneven wear. Also make sure the same construction type is used consistently if the truck is set up that way, and confirm that the tires actually match the size intended for the vehicle. A quick walk-around can reveal problems that are easy to miss in storage.

That routine is especially worthwhile on an occasionally driven Ford Bronco because long idle periods can hide slow leaks, flat spotting, or age-related cracking. A few minutes spent checking the tires before a drive is one of the simplest ways to protect both the vehicle and the people riding in it.

A Ford Bronco on original-style tires should be driven at moderate speeds that suit the tire construction, the condition of the tire, and the overall mechanical condition of the truck. Traditional bias-ply tires do not respond like modern radials, and truck-service tread patterns can feel different again. Even when the size is correct, age and setup matter just as much as the design itself.

The prudent approach with a Ford Bronco is to build speed gradually, pay attention to steering feel and stability, and avoid assuming highway behavior will match a modern vehicle. If the truck is fitted with period-style bias-ply tires, keeping speeds conservative and leaving extra stopping and steering margin is part of using the vehicle responsibly.
