Honda 600 Tires

Honda 600 brought small-displacement Japanese economy car thinking to the American market in the early 1970s, and its compact size makes it one of the more distinctive survivors from that era. Produced from 1971 through 1974, Honda 600 sits at an interesting point where very small-diameter wheels and more than one tire sizing convention can appear for the same car. Tire selection is not completely straightforward because the listings include both a modern-style radial size and an older numeric size for the same production years. Before choosing a tire for a Honda 600, the first job is to confirm the 10-inch wheel and then verify which size format matches the car's current wheels and intended use.

Honda 600 Tire Size Guide

Honda 600 uses 2 distinct tire sizes across the 1971 to 1974 production span. Both sizes fit 10-inch wheels, but they use two different sizing systems: one modern metric radial format and one older numeric bias-ply format. That difference matters because the tire code tells you very different things depending on which style your car uses.

145R101971-1974Euro-metric radial

145R10 is a radial size used on Honda 600 models from 1971 through 1974. The 145 indicates nominal section width in millimeters, the R identifies radial construction, and the 10 is the rim diameter in inches. Choose this size when your Honda 600 is set up for the metric radial fitment and you want the period small-car radial format used on a 10-inch wheel.

5.20-101971-1974Numeric bias-ply

5.20-10 is a numeric bias-ply size listed for Honda 600 models from 1971 through 1974. The 5.20 identifies the nominal section width in inches with the decimal shown, and the 10 is the rim diameter in inches. Choose this size when your Honda 600 is using the numeric bias-ply fitment for a period-correct presentation; A tube is required.

Honda 600 Tires by Year

The year listing below shows which tire sizes are associated with each Honda 600 production year from 1971 through 1974. Every listed year includes both 145R10 and 5.20-10, so the correct choice depends on the specific wheel and tire setup on the car rather than the year alone.

Frequently Asked Questions

The FAQ below addresses the two-size layout used across all Honda 600 years, the difference between metric radial and numeric bias-ply sizing, and the practical checks that matter before fitting new tires to a small 10-inch-wheel collector car.

Size Basics & Fitment

Honda 600 uses two listed tire sizes across the full 1971 through 1974 production span: 145R10 and 5.20-10. The 145R10 size is a radial built for a 10-inch rim, while 5.20-10 is a numeric bias-ply size that also fits a 10-inch rim. No year in the range is limited to only one of those sizes, so both appear throughout production.

That means year alone is not enough to choose a tire for a Honda 600. Start by checking the size stamped on the tire currently fitted, then confirm that the wheel is a 10-inch rim and decide whether the car is set up for metric radial or numeric bias-ply fitment. If the car is a restoration, compare that information against period photos, service literature, or the guidance of a Honda specialist.

On a Honda 600, 5.20-10 is a numeric bias-ply tire size. The 5.20 refers to the tire's nominal section width in inches, and the 10 is the rim diameter in inches. Unlike a modern metric radial size, it does not use a millimeter width and aspect-ratio format, and it represents an older style of sizing commonly associated with bias-ply construction.

That matters because a 5.20-10 Honda 600 tire should be selected as part of a bias-ply setup rather than treated as a direct modern metric code. If your car is meant to retain a more period-correct look and feel, this size may be the relevant path, but the wheel, tire profile, and intended use should all be checked together before fitting. Tube use is part of that decision with this style of tire.

A 1972 Honda 600 has two listed tire sizes because the fitment split is by construction and sizing system rather than by rim diameter. Both 145R10 and 5.20-10 fit 10-inch wheels, but 145R10 is a radial metric-style size and 5.20-10 is a numeric bias-ply size. The same two-size arrangement appears across 1971, 1972, 1973, and 1974.

For a Honda 600 owner, that means the car's actual wheel-and-tire setup needs to be identified before choosing a replacement. A restored car may favor the older numeric bias-ply appearance, while a driver-oriented car may already be running the metric radial format. Looking only at the model year can lead you in the right general direction, but the existing wheel and tire combination is the deciding factor.

Honda 600 tires in the 5.20-10 numeric bias-ply format require inner tubes. The 145R10 radial offerings are a different construction type and are not automatically grouped with that tube-required bias-ply fitment. Because both sizes are listed for the same years, tube requirement depends on which size and construction type the car is actually using.

The practical step is to treat tube selection as part of the full fitment package, not as an afterthought. If your Honda 600 is running or being restored with 5.20-10 bias-ply tires, include tubes in the plan from the start and inspect the wheels carefully before mounting. If the car is on 145R10 radials, confirm the wheel condition and compatibility with the radial tire being chosen.

Crossply vs Radial

Honda 600 is listed with both radial and bias-ply fitments, so the right choice depends on the car's current setup and the owner's goal. The radial choice is 145R10, while the bias-ply choice is 5.20-10. Radials generally suit owners who want a more modern driving feel within the listed fitment range, while bias-ply tires better preserve an older-period appearance.

Choosing between them starts with deciding whether the Honda 600 is being restored for authenticity, shown as a preserved period compact, or driven more regularly on present-day roads. Once that goal is clear, verify that the wheel, size format, and construction match each other. A thoughtful tire choice on a small car like the Honda 600 influences appearance, steering response, and the overall character of the car.

A Honda 600 fitted with 145R10 radial tires can feel different from one fitted with 5.20-10 bias-ply tires because the two constructions behave differently. Radials typically track and flex differently than bias-ply tires, and that can affect steering feel, straight-line behavior, and ride character. The size listings for Honda 600 support both approaches, so the driving impression may vary depending on which fitment the car carries.

That difference is especially noticeable on a very light, short-wheelbase car like the Honda 600. If the goal is to preserve a period driving sensation, a numeric bias-ply setup may align better with that objective; if the car is meant for regular hobby driving, the listed radial option may be the more appealing direction. Keeping all four tires in the same construction type is the sensible way to preserve predictable behavior.

A Honda 600 should not be treated casually when it comes to mixing 5.20-10 bias-ply tires and 145R10 radial tires. The two constructions are designed differently and can respond differently under braking, cornering, and load changes. Even though both sizes are listed for the model, that does not mean they should be combined indiscriminately on the same car.

The better practice is to keep a Honda 600 on one construction type across the full set so the car behaves consistently. If you are converting from one fitment style to the other, do it as a complete planned change rather than piecing it together one tire at a time. On a compact, low-weight collector car, consistency matters as much as the size itself.

Buying the Right Tire

A 1973 Honda 600 can use either 145R10 or 5.20-10, so the correct size is confirmed by the wheel-and-tire setup on the car rather than by the model year alone. Both are 10-inch fitments, but one is a radial metric-style size and the other is a bias-ply numeric size. The existing tire sidewall, wheel dimensions, and restoration goals together point to the right choice.

Begin by reading the tire size actually mounted on the Honda 600, then compare that to the wheel and the look you want the finished car to have. If the car has been changed over during its life, use service records, photographs, or marque expertise to determine whether to stay with the current arrangement or return to a more period-correct presentation. That approach is more reliable than selecting by year alone.

The listed Honda 600 products in 145R10 are blackwall tires. No alternate sidewall style appears among the available products for that size. The page's available radial offerings therefore point toward a straightforward small-car blackwall appearance rather than a whitewall presentation.

For most Honda 600 owners, that means the visual choice is simpler than it is on many larger collector cars. If appearance matters for restoration or show use, compare the blackwall look with period photos of similar cars and decide whether the current product selection suits the car's finish level and intended presentation. Sidewall style can influence the overall character of a very small car more than many owners expect.

Honda 600 tires in the listed 145R10 size are available from Firestone, Kings, Camac, Dunlop, and Vredestein. Those brands cover five radial products in the 10-inch metric-style fitment. Each represents a small-car radial approach rather than a bias-ply offering in the available product selection.

Brand choice on a Honda 600 should come after the size and construction are settled. Once you know the car needs 145R10 rather than 5.20-10, compare the available brands by the tire series, appearance, and how closely each option matches the car's intended use. A preserved original-style car and a regularly driven hobby car may point an owner toward different preferences even within the same size.

Honda 600 radial products in 145R10 include the Firestone F560 Radial, Kings Radial Tire, BN313 Radial from Camac, Dunlop SP Sport Aquajet, and Vredestein Sprint Classic. All are radial tire series built around the same general 10-inch fitment, but they represent different brand lines and tread families rather than one single universal product. The listed series do not indicate a switch between radial and bias-ply within that product group.

For a Honda 600 owner, series selection is mainly about choosing the radial product family that best suits the car's look and use once the 145R10 size has been confirmed. Some owners will prioritize a more period-looking small-car tread, while others may care more about matching a known classic-tire brand to the character of the car. The key is to separate the series decision from the more fundamental size-and-construction decision.

Maintenance & Longevity

A Honda 600 should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, and prolonged contact with petroleum products. Clean floors, stable temperatures, and proper inflation help reduce sidewall stress and flat spotting during long storage periods. Because Honda 600 uses very small 10-inch tires, changes in pressure and visible deflection can become noticeable quickly.

For a collector Honda 600 that sits for long periods, move the car occasionally or place it on appropriate supports so the same section of tire is not carrying load month after month. Check inflation before and after storage rather than assuming the tires have held pressure. Good storage habits preserve both appearance and service life, especially on compact vintage tires where small changes are easy to feel on the road.

Tires on a Honda 600 should be inspected regularly, with a close visual and pressure check before each driving outing and a more thorough inspection several times through the season. Look for cracking, bulges, tread separation, impact damage, uneven wear, and any sign that the tire is not seating or wearing evenly. On a collector car with small-diameter tires, even minor issues can affect how the car feels immediately.

A practical routine is to make tire inspection part of every pre-drive walkaround of the Honda 600. Check sidewalls, valve stems, and tread surfaces, then verify pressures with an accurate gauge before the car leaves the garage. If the Honda 600 has been stored for months or has recently returned to service, a more careful inspection by an experienced vintage-tire professional is a wise extra step.

A Honda 600 tire should be replaced when age, cracking, hardening, bulging, separation, impact damage, or persistent air loss indicate deterioration, even if the tread still looks usable. Collector-car tires often age out before they wear out, especially on lightly driven cars. Tread depth alone is not a reliable measure of serviceability on an older hobby vehicle.

The sensible approach is to judge a Honda 600 tire by condition, age, and inspection history rather than mileage. If the car has sat for years, if the tires are of uncertain age, or if the rubber has become visibly dry or stiff, replacement deserves serious consideration before regular driving resumes. A small, light car can still be strongly affected by aging tires, particularly in steering feel and braking consistency.

Restoration & Authenticity

Honda 600 is associated here with two period-appropriate size paths across 1971 through 1974: 145R10 and 5.20-10. The available products shown are radial offerings in 145R10, while the model-wide size listing also includes the numeric bias-ply 5.20-10 fitment. That tells you the Honda 600 can sit in either a radial or bias-ply conversation depending on the specific car and how it has been preserved or restored.

If originality matters on a Honda 600, use factory literature, surviving original tires, period photographs, and marque-club knowledge to determine what belongs on your exact car. The presence of two listed sizes means there is more than one historically plausible direction, but the correct answer for judging purposes rests with the individual car's specifications and restoration standard. Authenticity decisions should be made before cosmetic refinishing or wheel work begins.

Correct tire fitment can affect both the judged presentation and the perceived value of a Honda 600, especially because the car's small wheels and narrow tires are such a visible part of its overall proportion. Size, construction type, and sidewall appearance all influence whether the finished car reads as authentically restored or simply made roadworthy. On an unusual compact collector car, those details stand out quickly to knowledgeable observers.

For a Honda 600 being prepared for marque judging or a high-standard restoration, tire choice should match the car's era, finish level, and historical intent as closely as possible. A radial setup may suit a preservation-minded driver, while a numeric bias-ply presentation may better support a stricter period look. Club judges, Honda specialists, and period imagery remain the best references when authenticity carries real importance.

For Honda 600, the F560 Radial and Sprint Classic are two distinct radial tire series available in 145R10. Both are 10-inch radial fitments for the same model range, but they are separate brand families with their own tread design, construction tuning, and visual character. The difference is therefore a matter of product line and presentation within the same size category, not a change in basic fitment type.

When comparing radial series for a Honda 600, focus first on confirming that 145R10 is the correct fitment for the car. Once that is settled, the choice between series becomes a question of appearance, brand preference, and how the tire complements the personality of the finished car. On a compact classic, subtle differences in tread and profile can noticeably influence the car's visual stance.

Safety & Road Use

A properly fitted, correctly inflated, and sound-condition tire can make a Honda 600 suitable for normal hobby road use within the limitations of the car and the tire construction chosen. Safety depends on selecting the correct listed size, keeping all four tires in good condition, and matching the construction type to the intended use. A radial 145R10 setup and a 5.20-10 bias-ply setup can both be appropriate when fitted correctly.

Public-road use in a Honda 600 still calls for realistic expectations. It is a small, lightweight early-1970s car with very small-diameter tires, so road conditions, crosswinds, braking distances, and modern traffic speeds all deserve respect. Before regular driving, confirm age and condition of the tires, inspect the brakes and steering, and make sure the car behaves consistently at moderate speeds.

Before driving a Honda 600, check tire pressures, look closely for sidewall cracking or bulges, confirm there is no visible tread or casing damage, and make sure the tire size on the car matches the intended setup. If the car is on 5.20-10 bias-ply tires, include tube condition and any signs of valve-stem distress in the inspection. Because the tires are small and the car is light, changes in condition can show up quickly in steering feel.

A sensible pre-drive routine for a Honda 600 also includes verifying wheel fasteners, brake response, and basic steering behavior before heading into traffic. After long storage, do not assume the tires are ready simply because they still hold air. A short low-speed shakedown close to home is a smart way to confirm that the tire and wheel package is behaving as expected.

A Honda 600 should be driven at speeds appropriate to the tire construction, tire condition, and the car's overall mechanical state rather than by modern traffic expectations alone. Even when the listed size is correct, an older bias-ply setup and a radial setup may encourage different comfort levels in real use. Tire age and condition matter as much as size when deciding how the car should be driven.

The practical rule for a Honda 600 is to drive conservatively and build speed only after the tires, steering, and brakes have proven stable. A freshly inspected radial setup in sound condition may support more relaxed road use than an aging or more delicate bias-ply arrangement, but neither should be treated like a modern high-speed package. Collector-car enjoyment usually comes from preserving the car, not pushing its limits.
