1959 Austin-Healey Healey Tires

The 1959 Austin-Healey Healey uses two primary tire sizes: 590-15 in bias-ply construction and 165R15 in radial construction. Both sizes are associated with the Healey 100 6 and both use a 15-inch rim diameter, so the choice is not about a different wheel diameter so much as a different construction and sizing system.

That makes the next step more important than simply matching the rim diameter. A buyer should confirm which wheel width is on the car, decide whether the goal is traditional bias-ply character or a radial-format setup, and then compare sidewall style, tire series, and intended use before making the final choice.

The tire fitments used on the 1959 Austin-Healey Healey are built around a 15-inch rim diameter. That applies to both the 590-15 bias-ply size and the 165R15 radial size, so either path stays within the same basic wheel diameter even though the tire constructions differ.

Rim diameter alone is only part of the fitment picture on a Healey. Wheel width matters as well, especially if the car has replacement wires, steel wheels, or other non-original equipment, so it is smart to measure the wheel and compare it against the intended tire's rim-width specification before settling on a size.

590-15 is a vintage numeric bias-ply tire size. The 590 portion represents an approximate nominal section width of 5.90 inches, while the 15 identifies the wheel diameter in inches. On a 1959 Austin-Healey Healey, it refers to the traditional bias-ply fitment style rather than a modern metric radial size.

Understanding that difference helps avoid mixing sizing systems too casually. A 590-15 tire should be chosen with attention to wheel width, desired appearance, and whether the car is being kept in a more restoration-oriented configuration or being considered for one of the available radial-equivalent sizing paths.

590-15 is a bias-ply tire size on the 1959 Austin-Healey Healey. It is the vintage numeric fitment format associated with traditional construction, while 165R15 represents the radial-format option used on the same 15-inch rim diameter for this application.

That distinction affects both appearance and setup decisions. Bias-ply tires preserve a more traditional presentation, while a radial-format choice changes the construction and sizing convention, so the car's wheel width, suspension condition, steering clearance, and the owner's restoration goals should all be considered before switching paths.

Radial equivalents for 590-15 include 165R15 as the 80-series metric radial option, P165/75R15 as the P-metric 75-series radial option, and P175/70R15 as the P-metric 70-series radial option. These are the recognized radial alternatives connected to the original 590-15 bias-ply size on the 1959 Austin-Healey Healey.

Each equivalent should be treated as a comparison point rather than an automatic substitute. A 4-5 inch rim-width range is associated with this conversion path, and the buyer should still verify wheel width, tire dimensions, and body or steering clearance before changing from the original bias-ply fitment.

Start by confirming the wheel diameter and actual wheel width, then compare the intended radial size against the Healey's existing setup. For a car starting from 590-15 bias-ply tires, the recognized radial alternatives include 165R15, P165/75R15, and P175/70R15, but each needs to be evaluated against the specific wheel and car.

Construction changes can also bring appearance and fitment consequences beyond the size code itself. Check fender and steering clearance, inspect suspension and alignment condition, and make sure the selected tire suits how the car is driven, especially if it wears aftermarket wheels or has been altered from stock ride height.

The first decision is whether the Healey will remain on a traditional 590-15 bias-ply tire or use a 165R15 radial. After that, the main considerations are wheel-width compatibility, construction type, sidewall appearance, and the way the car will actually be used, whether for restoration-minded display, local driving, or more regular road use.

Product details help narrow the choice once the size path is settled. A buyer should compare the tire series available in the chosen size, note whether blackwall or whitewall styling better suits the car, and keep load and wheel specifications in view instead of selecting purely by appearance.

The available sidewall styles for a 1959 Austin-Healey Healey include blackwall, narrow whitewall, and wide whitewall, depending on the tire size and series selected. Those choices appear mostly in the 165R15 radial range, while 590-15 bias-ply options include blackwall and wide whitewall versions.

Sidewall style affects the car's presentation more than the fitment itself, but it should still be chosen within the correct size and construction path. A buyer aiming for a restrained sports-car look may prefer blackwall, while a more decorative vintage appearance may point toward one of the available whitewall treatments.

Tires for the 1959 Austin-Healey Healey are available from BFGoodrich, Avon, Michelin, Firestone, Vredestein, Coker Classic, and American Classic. Those brands appear across the two applicable size paths, with 165R15 carrying the broader radial assortment and 590-15 covering the more traditional bias-ply selections.

Brand alone should not drive the decision. It makes more sense to start with the correct size and construction, then compare the available tire series, sidewall style, rim-width specifications, and the kind of road use planned for the car before choosing among the brands represented in that fitment.

A period-style 1959 Austin-Healey Healey usually starts with the 590-15 bias-ply fitment, because that size and construction preserve the vintage numeric format and traditional visual character associated with the car's era. Blackwall and wide whitewall versions are both available within that bias-ply path.

The final appearance decision depends on how strictly the car is being restored and what presentation looks right for the individual vehicle. Owners pursuing exact historical accuracy should compare their choice against marque references, old photos, or restoration documentation, while others may simply want a traditional-looking tire in the proper size.

Tire construction changes the visual character of a restored 1959 Austin-Healey Healey more than many buyers expect. A 590-15 bias-ply keeps the car in a distinctly vintage sizing format, while a 165R15 radial introduces a more modern construction even when the overall look remains traditional and period-sensitive.

That difference is worth weighing alongside sidewall treatment. Blackwall, narrow whitewall, and wide whitewall choices can all shift the car's presentation, so a buyer should decide whether the project favors traditional sports-car restraint, a more decorative late-1950s look, or a balanced radial setup that still respects the car's era.

Yes, modifications can affect tire fitment on a 1959 Austin-Healey Healey even when the size code looks correct. Aftermarket wheels, changes in wheel width, suspension alterations, ride-height changes, or bodywork differences can all influence whether a 590-15 or 165R15 tire has the right relationship to the car.

A careful owner should measure the wheel, check steering travel, and look for clearance at the fenders and suspension before settling on a replacement tire. That matters even more when considering a radial-equivalent conversion from the original bias-ply sizing path, since construction changes can alter the fitment picture.

Before driving a 1959 Austin-Healey Healey on new tires, inspect the wheels for damage or corrosion, verify proper mounting on the correct rim diameter, and check that inflation is set appropriately for the chosen tire. It also helps to confirm even seating, valve condition, and basic clearance at full steering lock.

The rest of the car deserves attention too, especially on a collector sports car that may sit for long periods. Look over suspension and steering components, make sure alignment issues are not obvious, and recheck pressure and visual condition after the first few drives to catch settling or air-loss concerns early.

Collector-car tires on a 1959 Austin-Healey Healey should be maintained with regular pressure checks, visual inspections, and careful storage habits. Whether the car wears 590-15 bias-ply tires or 165R15 radials, owners should watch for sidewall cracking, tread damage, bulges, irregular wear, and slow air loss.

Low annual mileage does not remove the need for tire attention. A Healey stored for long periods benefits from a cool, dry environment away from direct sunlight and ozone sources, and it is wise to inspect the tires before each outing rather than assuming lightly used collector tires are automatically road-ready.
