In 1966, Austin-Healey stood at an interesting point in British sports car history, with the big-healey 3000 carrying the marque’s established grand-touring character while the Sprite delivered a lighter, simpler roadster experience. That split matters when sorting tire fitment, because 1966 Austin-Healey models do not share one universal size across the range. The 3000 uses 15-inch fitments with a choice between radial and bias-ply construction, while the Sprite uses 13-inch fitments with its own radial and bias-ply alternatives. Before choosing a tire for 1966 Austin-Healey vehicles, confirm whether you have a 3000 or a Sprite first, then decide whether originality or more modern road manners matters more to you.
Which Tire Size Is Right for Your 1966 Austin-Healey
Four tire sizes are available across 1966 Austin-Healey vehicles, and they vary by model rather than being shared across the full range. The main decision starts with identifying whether you have a 3000 or a Sprite, since those models use different rim diameters, and then choosing between a bias-ply or radial option within that model’s fitment family. Understanding that distinction before choosing a product saves time and helps you match the tire to the correct car and driving expectations.
Year(s): 1966|Fit(s): 3000|Construction: Radial|Rim: 15 in
165R15 is a radial metric size with a 165-millimeter section width and a 15-inch rim diameter, using the traditional Euro-metric convention that generally corresponds to an 80-series profile. This size is specific to the 1966 Austin-Healey 3000 and is available from Coker Classic, American Classic, Firestone, and BFGoodrich in blackwall, narrow whitewall, and wide whitewall styles. Buyers who want a radial for a 3000 often choose this size for more contemporary highway behavior while keeping the car on its correct 15-inch wheel diameter.
Year(s): 1966|Fit(s): 3000|Construction: Bias Ply|Rim: 15 in
590-15 is a numeric bias-ply size in which 5.90 denotes nominal section width and 15 denotes rim diameter, making it the period-style fitment family for a 15-inch wheel. This size is specific to the 1966 Austin-Healey 3000 and is available from BFGoodrich and Avon in blackwall and wide whitewall form, with H-rated Avon Turbospeed products carrying a 130 mph speed ceiling while other products in the size do not use that same speed marking. Buyers focused on a more era-correct look and traditional bias-ply feel will usually gravitate toward 590-15, especially for restoration-minded 3000 applications.
Year(s): 1966|Fit(s): Sprite|Construction: Radial|Rim: 13 in
145R13 is a radial metric size with a 145-millimeter section width and a 13-inch rim diameter, again using the classic Euro-metric format that conventionally implies an 80-series profile. This size is specific to the 1966 Austin-Healey Sprite and is available from Michelin and Firestone in blackwall form, with products in this size varying by product for speed marking and tube status, including an H-rated 145HR13 TL option with a 130 mph ceiling. Buyers who drive a Sprite regularly and want a radial construction on the original 13-inch wheel diameter will typically start here.
Year(s): 1966|Fit(s): Sprite|Construction: Bias Ply|Rim: 13 in
520-13 is a numeric bias-ply size in which 5.20 denotes nominal section width and 13 denotes rim diameter, preserving the smaller-period fitment used by the Sprite. This size is specific to the 1966 Austin-Healey Sprite and is available from Firestone and Premium Sport in blackwall and narrow whitewall styles. Buyers pursuing a more period-authentic appearance for a Sprite, especially one restored around its original small-car character, will often favor 520-13 over the radial alternative.
Two Austin-Healey models are covered for 1966, and they do not use the same tire sizes. The 3000 and Sprite differ not only in construction choices but also in rim diameter, so identifying the model is essential before narrowing your tire options. Select your model below to compare fitment history, size choices, and available products in more detail.
1966 Austin-Healey 3000
The Austin-Healey 3000 was the larger, more powerful Healey sports car, known for its long-hood British roadster proportions and strong grand-touring reputation. Its tire choices mount on 15-inch wheels, with one radial option and one bias-ply option that suit different restoration and driving priorities without changing the wheel diameter.
The Austin-Healey Sprite was the smaller, lighter member of the family, valued for its simplicity, nimble feel, and accessible British sports car character. Its tires mount on 13-inch wheels, and the available choices split between a radial for later-style drivability and a bias-ply for a more traditional look and feel.
Ten products are available across four tire sizes for 1966 Austin-Healey vehicles. 165R15 includes four radial choices from Coker Classic, American Classic, Firestone, and BFGoodrich in blackwall, narrow whitewall, and wide whitewall styles; 590-15 includes three bias-ply choices from BFGoodrich and Avon in blackwall and wide whitewall; 145R13 includes two radial blackwalls from Michelin and Firestone; 520-13 includes four bias-ply choices from Firestone and Premium Sport in blackwall and narrow whitewall styles. Confirm your model, size, and construction preference first, since speed markings and tube status can vary within a size.
These FAQs sort out the big-healey versus Sprite size split, the radial-versus-bias decision within each model, and practical details such as rim widths, sidewall styles, storage, and longer-drive checks for a collector Austin-Healey.
Size Basics & Fitment
What tire sizes fit 1966 Austin-Healey vehicles?
1966 Austin-Healey vehicles use four sizes across two model lines. The Austin-Healey 3000 uses 165R15 radial or 590-15 bias-ply tires on 15-inch rims, while the Austin-Healey Sprite uses 145R13 radial or 520-13 bias-ply tires on 13-inch rims. Rim width guidance appears within each size family: 165R15 fits 4.50 to 6.00-inch rims, 590-15 fits 4.00 to 4.50-inch rims where specified, 145R13 fits 4.00 to 5.00-inch rims where specified, and 520-13 ranges from 3.50 to 4.00 inches, with one product at 3.5 inches.
The practical takeaway is that year and make alone are not enough for a 1966 Austin-Healey tire decision. A 3000 owner should stay within the 15-inch fitment family, and a Sprite owner should stay within the 13-inch family before weighing radial versus bias-ply. Once the model is confirmed, wheel width is the next check, especially if the car has replacement rims or a long restoration history.
What does 590-15 mean on a 1966 Austin-Healey tire?
On a 1966 Austin-Healey, 590-15 is a classic numeric bias-ply size. The 5.90 portion refers to nominal section width in inches, while the 15 refers to the wheel diameter in inches. That format belongs to the traditional bias-ply sizing system commonly seen on mid-century British and American cars before metric radial sizing became widespread.
For a 1966 Austin-Healey 3000, 590-15 points you toward the original-style construction family rather than the later radial alternative. It is the size to consider when the car’s stance, sidewall look, and period presentation matter as much as the basic fit. If the car will be judged or restored to a 1960s appearance standard, this size is often the starting point before comparing blackwall and whitewall choices.
Do all 1966 Austin-Healey models use the same tire size?
No, 1966 Austin-Healey models do not share one universal tire size. The 3000 uses 15-inch fitments, with 165R15 as the radial choice and 590-15 as the bias-ply choice. The Sprite uses 13-inch fitments, with 145R13 as the radial choice and 520-13 as the bias-ply choice. That split reflects the very different size and mission of the two cars within the Austin-Healey range.
That matters because a buyer cannot safely choose a tire for 1966 Austin-Healey vehicles by year and make alone. A Sprite owner looking at 3000 sizes, or a 3000 owner looking at Sprite sizes, would immediately end up in the wrong wheel diameter. If the badge says Austin-Healey but the exact model is still in question, confirm that first before comparing construction type, sidewall style, or brand.
Buying the Right Tire
Should I choose the 165R15 or the 590-15 for my 1966 Austin-Healey?
For a 1966 Austin-Healey 3000, the real choice between 165R15 and 590-15 is radial versus bias-ply construction on the same 15-inch wheel diameter. The 165R15 uses a Euro-metric radial format and comes in blackwall, narrow whitewall, and wide whitewall versions. The 590-15 stays within the traditional numeric bias-ply family and is available in blackwall and wide whitewall form, with one Avon H-rated version marked for a 130 mph ceiling.
A 3000 owner usually leans toward 590-15 when the goal is a more period-correct appearance and traditional bias-ply character. A 165R15 often makes sense when the car will be driven more regularly and the owner wants a radial construction while keeping the original wheel diameter. Neither choice should be treated as automatic; the best pick depends on how original the car needs to look and how it will actually be used.
What sidewall styles are available for 1966 Austin-Healey tires?
1966 Austin-Healey tires are available in several sidewall styles depending on size. The 165R15 range for the 3000 offers blackwall, narrow whitewall, and wide whitewall choices, while 590-15 offers blackwall and wide whitewall. The Sprite’s 145R13 radial choices are blackwall only, and 520-13 bias-ply choices include blackwall and narrow whitewall.
Sidewall style affects the visual character of the car as much as the fitment itself. On a 1966 Austin-Healey, blackwalls are the safest choice when aiming for a straightforward sporting look, while whitewall width needs a little more thought because it can shift the car toward a more personalized or market-specific presentation. If the car is being restored for judged events, compare the sidewall style against period photos and club guidance before deciding.
What brands make tires for 1966 Austin-Healey vehicles?
Several brands cover 1966 Austin-Healey fitments. The 3000’s 165R15 size is available from Coker Classic, American Classic, Firestone, and BFGoodrich, while its 590-15 size is available from BFGoodrich and Avon. The Sprite’s 145R13 size is available from Michelin and Firestone, and its 520-13 size is available from Firestone and Premium Sport.
That mix gives Austin-Healey owners a choice between heritage names and different visual presentations without changing away from the correct size family for the model. Brand selection often comes down to whether you want a blackwall or whitewall, whether you want radial or bias-ply construction, and whether the car is being restored for authenticity or prepared for regular hobby driving. Start with the right model and size, then narrow by brand character and sidewall appearance.
Fitting & Setup
What rim width do 1966 Austin-Healey tires require?
Rim width depends on the exact 1966 Austin-Healey size. The 3000’s 165R15 radial fits 4.50 to 6.00-inch rims, while 590-15 bias-ply products with published wheel guidance fit 4.00 to 4.50-inch rims. The Sprite’s 145R13 radial fits 4.00 to 5.00-inch rims, and 520-13 bias-ply products fit either a 3.5-inch rim or a 3.50 to 4.00-inch rim range depending on the product.
That range is why wheel verification matters before committing to a tire, especially on a sports car that may have had wheel changes during its life. A 15-inch rim is not enough information for a 3000, and a 13-inch rim is not enough information for a Sprite. Measure the wheel, confirm the diameter, and check the actual width between bead seats so the selected tire falls within its intended mounting range.
Do 1966 Austin-Healey tires require inner tubes?
Inner-tube requirements vary across 1966 Austin-Healey sizes and sometimes vary within the same size. The Sprite’s 145R13 range includes a Michelin 145HR13 marked TL, which identifies it as tubeless, while other products in that size do not use the same marking. The 165R15, 590-15, and 520-13 products do not present one consistent tube designation across every option, so tube use should be confirmed against the exact tire and the wheel design.
That matters because a tire’s construction and a wheel’s original sealing design are separate issues. A tubeless-marked tire may still be paired with a tube on some older wheels, and some vintage wheel types are better suited to tube-type service. Before final installation, check the tire’s sidewall marking, inspect the wheel condition, and confirm the recommendation for your specific tire-and-wheel combination rather than assuming every product in the size is handled the same way.
Can the original 1966 Austin-Healey wheels be used with both tire sizes for each model?
Within each 1966 Austin-Healey model family, both available sizes share the same wheel diameter. The 3000’s 165R15 and 590-15 both mount on 15-inch wheels, and the Sprite’s 145R13 and 520-13 both mount on 13-inch wheels. That means the original wheel diameter stays consistent even when you choose between radial and bias-ply construction for the same model.
The remaining question is wheel width, not wheel diameter. A 3000 owner comparing 165R15 to 590-15 should verify that the wheel falls within the approved width range for the chosen tire, and the same is true for Sprite owners comparing 145R13 to 520-13. Diameter compatibility is straightforward here, but width and wheel condition still need to be confirmed before mounting.
Maintenance, Storage & Longevity
How should I store a 1966 Austin-Healey when the tires are fitted?
A stored 1966 Austin-Healey should be kept in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age rubber prematurely. Clean tires with mild soap and water only, maintain proper inflation, and move the car periodically or support it carefully if it will sit for a long period. Bias-ply tires on a 3000 or Sprite are more prone to temporary flat-spotting during static storage than radials.
Good storage habits help preserve both appearance and drivability, especially on a lightweight sports car that may spend much of the year parked. If the car returns to the road after months of rest, let the tires warm gradually and watch for vibration that does not clear up as the drive continues. Collector cars often age their tires by time and environment more than by mileage, so storage conditions matter as much as road use.
How long do tires on a 1966 Austin-Healey typically last?
Tires on a 1966 Austin-Healey are usually judged by age and condition more than by tread wear. Many collector-car owners begin careful evaluation at five to seven years and treat the ten-year point as a strong replacement consideration, even if the tread still looks usable. The DOT date code on the tire is the practical starting point for tracking age, and visible cracking, hardening, vibration, or persistent air loss can move replacement earlier.
That guideline matters because sports cars like the Austin-Healey 3000 and Sprite often cover limited annual mileage. A tire can look serviceable after years of occasional drives yet still be past its most dependable age window. If the car has recently returned from long storage or an older restoration, check the actual tire age before focusing on cosmetic condition alone.
How often should tires on a 1966 Austin-Healey be inspected?
Tires on a 1966 Austin-Healey should be inspected before every drive and again before any longer outing. Look for sidewall cracking, weather checking, uneven tread wear, punctures, bulges, embedded debris, and pressure loss. If your chosen tire-and-wheel combination uses tubes, valve stems and slow leaks deserve extra attention because a collector car can sit long enough for a marginal component to become a roadside problem.
Frequent inspection is especially worthwhile on older sports cars because they are sensitive to small changes in tire condition and inflation. A quick walk-around can catch issues before they affect steering feel, braking stability, or the spare tire’s usefulness. Build tire inspection into the same routine as fluid, brake, and lighting checks whenever the car comes out for a drive.
Restoration & Authenticity
What tires were originally fitted to the 1966 Austin-Healey 3000?
For a 1966 Austin-Healey 3000, bias-ply construction is the historically expected starting point for original-style fitment, and 590-15 represents that traditional size family. The radial 165R15 is a later-style alternative that keeps the 15-inch wheel diameter but does not mirror the same period construction. Original-equipment brand could vary by market and delivery details, so construction type and size family matter more than assuming one universal brand name.
That makes 590-15 the logical first stop when restoring a 3000 to a 1960s presentation standard. Owners seeking event-level authenticity should also pay attention to sidewall style, since blackwall and whitewall choices can change the visual correctness of the finished car. For final confirmation on a particular chassis, market, or judging standard, Austin-Healey marque clubs and factory literature remain the best references.
Does correct tire fitment matter for showing a 1966 Austin-Healey?
Correct tire fitment can matter a great deal when showing a 1966 Austin-Healey, especially in classes that emphasize factory appearance. Judges and knowledgeable enthusiasts often notice size family, construction type, rim diameter, and sidewall style before they notice smaller tire details. A Sprite on a 15-inch 3000 size, or a 3000 on a modern-looking radial when originality is the goal, can stand out for the wrong reason.
For a show-focused car, think of the tire as part of the restoration rather than an isolated replacement item. The right bias-ply or radial choice depends on the standard you are restoring toward, and the correct sidewall treatment can be just as important as the size itself. Event rules and marque-club judging guides should be the final word when concours accuracy matters.
What is the difference between the Firestone and Premium Sport 520-13 tires for the 1966 Austin-Healey?
For the 1966 Austin-Healey Sprite in 520-13, Firestone and Premium Sport serve different visual and specification niches within the same bias-ply size family. Firestone offers a blackwall classic bias-ply with a published 770-pound maximum load at 32 psi and a 3.5-inch rim fitment, while Premium Sport focuses on narrow whitewall versions, including a 1.25-inch whitewall with a published 1100-pound maximum load at 60 psi and a 3.50 to 4.00-inch rim range.
That means the choice is not just brand loyalty; it also affects appearance and setup details. A Sprite owner chasing a simple sporting blackwall look may gravitate toward Firestone, while an owner restoring a particular custom-period or market-specific whitewall presentation may prefer Premium Sport. Because the published wheel and pressure figures differ, compare the exact product against your wheel before making the final decision.
Safety & Road Use
Are 1966 Austin-Healey tires safe for highway driving?
1966 Austin-Healey tires can be suitable for highway driving when they are the correct size, in good condition, and matched to the car’s wheel and intended use. The 145R13 range includes an H-rated Michelin option with a 130 mph ceiling, and the 590-15 range includes an H-rated Avon option with the same 130 mph ceiling. Other products in these fitment families may not carry identical speed markings, so the exact tire matters more than the size name alone.
On a mid-1960s Austin-Healey, real-world highway confidence depends on more than tire speed rating. Brake condition, steering play, suspension wear, alignment, and the car’s overall mechanical health usually become limiting factors before an enthusiast approaches the upper edge of an H-rated tire. Match the tire to the way the car will actually be driven, and treat condition and setup as seriously as the speed symbol.
What inflation pressure should I use for 1966 Austin-Healey tires?
Inflation pressure for 1966 Austin-Healey tires should begin with the vehicle manufacturer’s recommendation for the model and then be checked against the reproduction tire’s own rated pressure information. Published maximum load and pressure figures vary by size and product: 165R15 appears at 1168 pounds at 35 psi or 1170 pounds at 36 psi, 590-15 appears at 1050 pounds at 32 psi, 145R13 appears at 825 pounds at 44 psi on one product, and 520-13 appears at 770 pounds at 32 psi or 1100 pounds at 60 psi depending on the product.
Those figures are not direct instructions to inflate every tire to its maximum pressure. They show why one Austin-Healey size cannot borrow another size’s settings, and why even two products with the same nominal size may call for different treatment. Use the car maker’s baseline as your starting point, then confirm the exact tire’s sidewall and manufacturer guidance before finalizing cold pressures.
What should I check before taking a 1966 Austin-Healey on a longer drive?
Before a longer drive in a 1966 Austin-Healey, inspect each tire for cracks, cuts, bulges, punctures, uneven wear, and signs of age hardening. Verify cold inflation pressures, check that valve stems are sound, and make sure the spare is inflated and serviceable. If the car runs a tube-type setup, include the condition of the tube-related hardware in your planning, since a long-stored collector car can reveal small air-loss issues only after a sustained run.
A longer-drive inspection should also extend beyond the tires because an Austin-Healey’s age makes every supporting system part of the safety equation. Brakes, wheel bearings, steering components, cooling, and charging should all be looked over with the same seriousness. Tires are the car’s contact patch, but they perform best when the rest of the chassis is equally ready for the trip.
