1958 Austin-Healey Healey Tires

The 1958 Austin-Healey Healey uses two recognized tire sizes: 590-15 in bias-ply construction and 165R15 in radial construction. Both sizes are associated with 15-inch rims, so the basic fitment question is less about wheel diameter and more about which construction and sizing system best suits the car.

That choice affects appearance, wheel-width compatibility, and the overall character of the tire package. A 590-15 keeps the traditional numeric bias-ply format, while 165R15 moves to a Euro-metric radial. Before selecting either one, confirm the actual wheels on the car, especially if it has been changed from its earlier setup over the years.

The tire sizes used on the 1958 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 fitment starts with the same wheel diameter even though the tire construction and sizing format differ.

Rim diameter is only part of the picture, especially on a vintage sports car. Wheel width also matters, and some 165R15 radial options are intended for a broader width range than 590-15 bias-ply tires. Measuring the actual wheels before buying is worthwhile, particularly if the car has replacement steel wheels or aftermarket wires.

Yes. The 1958 Austin-Healey Healey 100 6 is associated with the same two tire sizes used here: 590-15 in bias-ply form and 165R15 in radial form. That keeps sub-model fitment straightforward, because there is no separate alternate size tied only to the 100 6 in this application.

Even with shared fitment, the tire decision still depends on how the car is being used and presented. A restoration-oriented owner may want the traditional bias-ply size, while another owner may prefer a radial in the companion 15-inch fitment. Checking the wheel width and any past suspension or wheel changes remains a smart final step.

590-15 is the bias-ply tire size associated with the 1958 Austin-Healey Healey. It uses the older numeric sizing system, and in this application it represents the traditional construction choice compared with the 165R15 radial alternative that uses the same 15-inch rim diameter.

Staying with 590-15 usually appeals to owners who want a more traditional presentation and an older-style sizing format. Moving away from it changes both construction and tire profile convention, even when wheel diameter remains the same. Wheel width, body clearance, and the condition of the suspension should all be reviewed before changing setups.

Radial equivalents for 590-15 include 165R15 as an 80-series metric radial, P165/75R15 as a 75-series P-metric radial, and P175/70R15 as a 70-series P-metric radial. Those sizes give the 1958 Austin-Healey Healey several radial comparison points without changing away from a 15-inch wheel diameter.

Each equivalent uses a different sizing convention, so the choice is not just radial versus bias-ply. The equivalent range is associated with a 4-5 inch rim-width range, and the actual car should still be checked for wheel width, tire clearance, and overall proportions. An equivalent size is a useful alternative, not an automatic interchange.

Start by confirming the actual wheel diameter and width, then compare the radial size being considered against the car’s current setup. On a 1958 Austin-Healey Healey, that often means evaluating whether the move from 590-15 bias-ply to 165R15 or another stated radial equivalent matches the wheels already on the car.

Clearance at the fenders and steering components should be checked with the suspension loaded, not just with the car at rest. It also helps to inspect the condition of the steering and suspension before the change, since vintage components can influence how well a new tire setup behaves once the car is back on the road.

The first decision is whether the car should stay with the 590-15 bias-ply size or use the 165R15 radial fitment. After that, compare wheel-width compatibility, sidewall style, brand, and the visual character of the tire so the selection suits both the car and the way it will be driven.

A traditional bias-ply setup makes sense when vintage presentation is the priority, while a 165R15 radial opens up more product variety. It helps to look at blackwall, narrow whitewall, and wide whitewall options alongside rim-width specifications instead of focusing on size alone. The right choice is the one that matches the actual wheels and the car’s intended use.

The 1958 Austin-Healey Healey has product choices in blackwall, narrow whitewall, and wide whitewall sidewall styles. Those options appear across the 165R15 radial range, while the 590-15 bias-ply selection includes blackwall and wide whitewall versions for buyers who want a more traditional numeric-size tire.

Sidewall style changes the car’s visual balance more than many owners expect, especially on a small British sports car. Blackwall usually gives the most understated presentation, while narrow and wide whitewalls create progressively stronger vintage emphasis. Appearance should be matched to the rest of the car rather than treated as a separate decision from size and construction.

Tires for the 1958 Austin-Healey Healey are available from Michelin, Vredestein, BFGoodrich, Firestone, American Classic, Avon, and Coker Classic. Most of that variety appears in the 165R15 radial category, while 590-15 bias-ply choices include BFGoodrich and Avon offerings in traditional vintage-style formats.

Brand choice is most useful when compared alongside construction, sidewall style, and tire series rather than treated as the only deciding factor. Some buyers will be narrowing by blackwall versus whitewall, while others are sorting between radial and bias-ply first. Looking at the full specification set keeps the decision practical and vehicle-specific.

A period-style 1958 Austin-Healey Healey usually starts with the 590-15 bias-ply size, since it preserves the traditional numeric sizing format and older tire construction associated with the car’s era. That makes it the natural first place to look when the goal is a more vintage presentation rather than a modernized radial setup.

The final choice still depends on how exact the restoration needs to be and how the car will actually be used. A radial can still suit a restoration-oriented car when road use matters more than strict period feel. For originality-focused judging, marque references and vehicle-specific historical documentation are worth consulting before settling on sidewall style and brand.

Tire construction changes more than the internal build of the tire; it also changes the visual language of the car. On a restored 1958 Austin-Healey Healey, a 590-15 bias-ply tends to preserve the traditional vintage sizing impression, while a 165R15 radial gives the car a later-style metric presentation on the same 15-inch wheel diameter.

That difference becomes even more noticeable once sidewall treatment enters the picture. Blackwall, narrow whitewall, and wide whitewall choices each push the car in a different direction visually. Construction should be selected as part of the full restoration presentation, not as an isolated specification, especially on a car where tire shape contributes strongly to stance.

Yes. Modifications can change how either a 590-15 bias-ply or 165R15 radial sits on a 1958 Austin-Healey Healey, even when the wheel still measures 15 inches. Aftermarket wheels, altered wheel width, suspension changes, or body adjustments can all change the amount of available clearance around the tire.

A car that has been lowered, fitted with different wheels, or rebuilt with non-stock components deserves a closer fitment check before new tires go on. Steering travel and fender clearance should be reviewed with the car on the ground. That is especially important when moving from one tire construction or equivalent sizing format to another.

Before road use, inspect wheel condition, valve stems, lug hardware, and basic suspension and steering health on the 1958 Austin-Healey Healey. New tires should also be checked for proper inflation, even seating on the rim, and adequate clearance around the fenders and steering components once the car is resting at normal ride height.

A short, careful shakedown drive is worthwhile before taking the car on a longer run. Recheck pressure afterward and look for any signs of rubbing or unusual wear. Vintage sports cars often spend long periods parked, so it is smart to treat the whole wheel-and-tire system as a package rather than assuming fresh rubber alone solves every road-use issue.

Tires on a collector 1958 Austin-Healey Healey should be inspected regularly for pressure loss, sidewall cracking, tread wear, bulges, cuts, and any signs of age-related hardening. That matters whether the car is running 590-15 bias-ply tires or 165R15 radials, because low annual mileage can hide condition issues that only show up during closer inspection.

Storage conditions make a real difference on a low-use car. Keeping the Healey away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires between drives. It also pays to look over the tires before every outing, since collector cars often sit long enough for small air-loss or age-related problems to go unnoticed.
