1958 Austin-Healey Sprite Tires

A 1958 Austin-Healey Sprite uses two primary tire sizes: 520-13 in bias-ply construction and 145R13 in radial construction. Both sizes are built for 13-inch rims, so the decision is less about diameter and more about whether the car is staying with a traditional bias-ply format or moving to a metric radial setup.

That choice affects both appearance and fitment review. A bias-ply 520-13 keeps the vintage numeric sizing system, while 145R13 uses a Euro-metric radial format. Before selecting either one, confirm the actual wheel width on the car and make sure the Sprite has not been altered with aftermarket wheels or suspension changes that could influence clearance.

The 1958 Austin-Healey Sprite uses 13-inch rims with both of its primary tire sizes. The bias-ply 520-13 and the radial 145R13 are both tied to that same rim diameter, which simplifies the starting point for tire shopping compared with vehicles that used more than one wheel diameter.

Rim diameter is only the first step, though. Wheel width still matters, especially when comparing a vintage bias-ply tire with a radial or one of the radial equivalents for 520-13. It is smart to verify the wheels actually on the car before ordering, since later replacement wheels can change what works comfortably and what may create rubbing or bead-seat concerns.

The covered 1958 Austin-Healey Sprite Mark I, II, III, IV fitment remains consistent, with the same two tire choices used across the sub-model group: 520-13 bias-ply and 145R13 radial. That means there is no separate trim-specific diameter to sort out within this range.

Even with shared sizing, the right tire still depends on the car's present configuration and the owner's priorities. One Sprite may be aimed at a more restoration-oriented look with a bias-ply tire, while another may be considered for radial use. Checking the wheels and confirming whether the car still has its intended 13-inch setup keeps that shared fitment from becoming a mistaken assumption.

On a 1958 Austin-Healey Sprite, 520-13 is a bias-ply tire size. It uses the older numeric sizing system common to many period vehicles, and it appears in available products as a traditional bias-ply choice with blackwall, narrow whitewall, and wide whitewall sidewall treatments.

That makes 520-13 especially relevant for owners who want a more vintage presentation. A radial alternative can still be considered, but the construction change should not be treated casually. Wheel width, overall dimensions, and clearance around the fenders and steering components should all be checked before substituting a radial-equivalent size for the original-style bias-ply format.

Radial equivalents for 520-13 include 155R13 as an 80-series metric radial, P155/75R13 as a P-metric 75-series radial, and P155/70R13 as a P-metric 70-series radial. These are equivalent-size alternatives for the original bias-ply fitment, not additional primary tire sizes for the 1958 Austin-Healey Sprite.

Each one uses a slightly different sizing convention, so the comparison should go beyond the size code alone. A recommended rim-width range of 4 to 5 inches is associated with these equivalents, and the car should be checked for wheel compatibility and clearance before making the change. That is especially important on a small sports car where tire space is limited.

Start by confirming the wheel diameter and actual wheel width, then compare the intended radial size with the Sprite's current setup. For a 520-13 bias-ply tire, radial-equivalent options include 155R13, P155/75R13, and P155/70R13, with a recommended rim-width range of 4 to 5 inches attached to those equivalents.

The next concerns are clearance and condition. Make sure the tire does not crowd the fender opening or steering travel, and inspect suspension and steering parts for wear before evaluating how the car behaves on a different construction. A Sprite that still has older wheels, changed ride height, or nonstandard alignment settings deserves extra fitment review before the swap.

The first decision is whether 520-13 is the look and construction you want for the car, since it is the bias-ply option for the 1958 Austin-Healey Sprite. Within that size, choices vary by brand, sidewall style, tire series, and in some cases rim-width specification and load information tied to a stated inflation pressure.

A buyer focused on period-style presentation may lean toward blackwall or whitewall appearance first, while another owner may compare brand and series character before narrowing the choice. Wheel width should still be verified on the car, and any owner planning regular road use should also look at the product's construction details rather than selecting only by sidewall style.

1958 Austin-Healey Sprite tires are available with several sidewall treatments depending on the size and tire series. The 145R13 radial options are blackwall, while 520-13 bias-ply choices include blackwall, narrow whitewall, and wide whitewall versions.

That gives the Sprite owner a clear appearance decision. Blackwall usually keeps the presentation simple and sporting, while narrow or wider whitewall styles push the car toward a more stylized vintage look. Sidewall style should be chosen after the correct size and construction are settled, since appearance does not override the need to match the wheel diameter and intended vehicle use.

Tires for the 1958 Austin-Healey Sprite are available from Michelin, Firestone, and Premium Sport. Michelin and Firestone appear in the 145R13 radial size, while Firestone and Premium Sport offer 520-13 bias-ply choices across different sidewall presentations and tire series.

Brand is only one part of the decision. It makes more sense to compare the brand together with construction type, sidewall style, tire series, and the wheel specifications tied to the product. That approach helps narrow the selection to a tire that suits the Sprite's appearance and setup, rather than choosing by name alone and sorting out fitment later.

For a period-style 1958 Austin-Healey Sprite, the 520-13 bias-ply size is the natural starting point because it preserves the vintage numeric sizing format and traditional construction. Available choices in that size include blackwall, narrow whitewall, and wide whitewall versions, giving the car a range of restoration-oriented visual directions.

The exact sidewall treatment should match the look you want the Sprite to carry, not just the fact that a tire fits the wheel diameter. When originality matters at a very high level, compare the tire choice against marque-club knowledge or period vehicle documentation. That helps separate a convincing period-style presentation from a tire that is merely available in the right size.

Tire construction changes more than ride characteristics on a restored 1958 Austin-Healey Sprite; it also changes how the car reads visually. A 520-13 bias-ply tire keeps the small British sports car in a more traditional late-1950s presentation, while a 145R13 radial introduces a more modern metric format and a different overall tire character.

That does not mean one look is automatically right and the other wrong. A restoration-minded owner may prefer the older bias-ply profile and sidewall styling, while a driver-oriented owner may accept the radial look to suit road use goals. The important step is choosing the construction deliberately so the tire's appearance supports the Sprite's intended finish.

Yes, modifications can affect tire fitment on a 1958 Austin-Healey Sprite even when the tire size itself is correct on paper. Aftermarket wheels, different wheel widths, altered offset, suspension changes, ride-height adjustments, or body repairs can all influence how a 520-13 or 145R13 tire sits in the car.

A small sports car leaves less room for assumptions, so the actual setup deserves a close look. Check steering travel, inner and outer clearance, and the wheel dimensions before treating any tire as an automatic match. Even a radial equivalent for 520-13 should be evaluated on the finished car rather than selected solely by size code.

Before driving a 1958 Austin-Healey Sprite on new tires, inspect the wheels for correct diameter and width, make sure lug hardware and wheel seating surfaces are in good condition, and confirm the tires are mounted and inflated properly. A quick visual check for sidewall damage, bead issues, or uneven seating is also worthwhile before the first road test.

The car itself needs attention too. Look at steering and suspension wear, verify there is no rubbing at full lock, and recheck pressure after the first few miles. On a lightly used collector car, do not assume the rest of the chassis is ready just because the tires are new. Old bushings, alignment drift, or worn dampers can still affect how safely the Sprite behaves.

Collector-car tires on a 1958 Austin-Healey Sprite should be maintained with regular pressure checks, visual inspection, and careful storage habits. Whether the car is on 520-13 bias-ply tires or 145R13 radials, watch for cracking, bulges, cuts, uneven tread wear, and slow air loss, especially if the Sprite spends long periods parked.

Storage conditions matter almost as much as miles driven. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the sidewalls over time. It also makes sense to inspect the tires before every meaningful drive rather than relying on tread depth alone, since aging often shows up first in condition changes instead of outright wear.
