The 1960 Fairthorpe Electron belongs to a small-displacement British sports-car tradition that favored light weight, simple mechanicals, and nimble road manners over brute power. Cars like the Electron reward careful component choices because tire size and construction have a noticeable effect on stance, steering feel, and overall character. For this exact model, the key fitment question centers on two 15-inch tire paths: the original-style 560-15 bias-ply size and the 155R15 radial alternative. That opens the door to blackwall, narrow whitewall, and wide whitewall bias-ply choices, along with several blackwall radial series. The right decision depends on whether the goal is traditional presentation, road-use practicality, or a balanced restoration-minded setup.
Which Tire Size Is Right for The 1960 Fairthorpe Electron
The 1960 Fairthorpe Electron uses two 15-inch tire sizes: 560-15 in bias-ply construction and 155R15 in radial construction. Because both sizes appear on the Electron MK II, the main decision is not wheel diameter but which construction and presentation best suit the car. One path keeps a more traditional bias-ply look, while the other moves to a Euro-metric radial format with a broader range of road-use tire choices.
155R15 is a Euro-metric radial size in which 155 indicates nominal section width in millimeters, R denotes radial construction, and 15 identifies the wheel diameter in inches. On the 1960 Fairthorpe Electron, this size provides a radial-format option while staying on a 15-inch rim. Available choices are centered on blackwall tires from Firestone, Michelin, Avon, and Vredestein across series such as F560 Radial, Michelin X, Michelin XAS, CR6ZZ, Snow Classic, and Sprint Classic. It is a useful size to evaluate when the goal is radial construction, period-sensitive blackwall appearance, and compatibility with the car's existing 15-inch wheel setup.
560-15 is a numeric bias-ply size in which 560 represents a nominal section width of about 5.60 inches and 15 is the wheel diameter in inches. For the 1960 Fairthorpe Electron, it is the traditional bias-ply fitment path and preserves the sizing language commonly associated with many period vehicles. Product choice is unusually broad, with blackwall, narrow whitewall, and wide whitewall options from Firestone, US Royal, and Coker Classic, plus a Pro-Trac Street Pro Front Runner variant. This size deserves a close look when maintaining a more authentic visual character matters as much as simple 15-inch fitment.
Sub-model fitment is straightforward here because the covered 1960 Fairthorpe Electron MK II uses the same two 15-inch tire sizes already associated with the model core. Checking the sub-model still matters, since the real choice is whether the car is being kept on the traditional bias-ply size or moved to the radial-format alternative.

1960 Fairthorpe Electron MK II
The 1960 Fairthorpe Electron MK II can be fitted with either the 560-15 bias-ply size or the 155R15 radial size on 15-inch wheels. That gives the buyer a clear choice between a more traditional period-style tire presentation and a radial-format setup that should still be checked against wheel width and overall vehicle clearance.
Bias-Ply to Radial Tire Conversion for the 1960 Fairthorpe Electron
For the original-style 560-15 tire size, two radial-equivalent options are available. 155R15 serves as the 80-series metric radial equivalent, while 560R15 is the bias-look radial equivalent. The first uses Euro-metric radial sizing, and the second is aimed at retaining a more traditional visual presentation while moving to radial construction. A recommended rim-width range of 4 to 5 inches applies to these alternatives, so wheel width, overall dimensions, and clearance should all be confirmed before changing from the primary bias-ply size.

Tire Size & Fitment
What tire size fits a 1960 Fairthorpe Electron?
The 1960 Fairthorpe Electron uses two tire sizes: 560-15 in bias-ply construction and 155R15 in radial construction. Both are 15-inch fitments, so the main distinction is not wheel diameter but tire type, sizing format, and the kind of driving or appearance goal the owner has in mind.
Choosing between them starts with the car's actual wheel setup and the look you want. A 560-15 keeps the traditional numeric bias-ply presentation, while 155R15 moves to a Euro-metric radial format. If the car has been modified over the years, confirm wheel width and available clearance before assuming either size is suitable for the current setup.
What size rim does a 1960 Fairthorpe Electron use?
The applicable tire sizes for a 1960 Fairthorpe Electron both use a 15-inch rim diameter. That includes the 560-15 bias-ply size and the 155R15 radial size, so any tire selection for this page begins with a 15-inch wheel rather than multiple rim-diameter options.
Rim diameter is only the first check, especially on a collector car that may no longer wear its original wheels. Wheel width still matters because the available tires span different recommended rim-width ranges. Verifying the stamped wheel size or measuring the wheel before purchase helps avoid choosing a tire that matches diameter but is not well suited to the rim itself.
What does 560-15 mean on a 1960 Fairthorpe Electron?
560-15 is a numeric bias-ply tire size. The 560 portion represents a nominal section width of about 5.60 inches, and the 15 indicates a 15-inch wheel diameter. On a 1960 Fairthorpe Electron, that size points to the traditional bias-ply fitment route rather than a modern metric radial format.
That matters because the size code influences both appearance and construction choice. A buyer looking at 560-15 will typically be deciding among blackwall, narrow whitewall, or wide whitewall bias-ply options, or considering a radial equivalent separately. The size should still be matched to the actual wheel and checked against the car's current ride height and body clearance.
Bias-Ply & Radial Options
Is 560-15 a bias-ply or radial tire for the 1960 Fairthorpe Electron?
On the 1960 Fairthorpe Electron, 560-15 is a bias-ply tire size. It uses the older numeric sizing format and represents the traditional tire construction path for this car, as opposed to the 155R15 radial size that appears as the radial-format alternative on the same 15-inch rim diameter.
That distinction affects more than the lettering on the sidewall. Staying with 560-15 bias-ply usually appeals to owners who want a more period-style look and the tire options that come with it, including different whitewall treatments. Before changing constructions, compare the wheel width and the car's current setup so the new tire choice matches both the rim and the body clearance.
What radial tire sizes are equivalent to 560-15?
Radial equivalents for 560-15 include 155R15 and 560R15. The 155R15 is the 80-series metric radial equivalent, while 560R15 is the bias-look radial equivalent for buyers who want radial construction in a size that keeps a more traditional visual theme.
A recommended rim-width range of 4 to 5 inches applies when evaluating these radial alternatives. Equivalent sizing is a comparison point rather than an automatic interchange, so the wheel width, overall tire dimensions, and available clearance should all be checked carefully. That is especially important on a lightweight sports car where even small fitment changes can alter the car's stance and feel.
Should I use bias-ply or radial tires on a 1960 Fairthorpe Electron?
The answer depends on how the 1960 Fairthorpe Electron is being used and presented. A 560-15 bias-ply tire keeps the traditional size and appearance language of the period, while 155R15 gives the car a radial-format option on the same 15-inch rim diameter. Both fitment paths are relevant for this model.
A restoration-oriented owner may prefer the visual character of bias-ply, especially when choosing among blackwall or whitewall treatments. A driver focused on a radial setup may lean toward 155R15 or a bias-look radial alternative. The best next step is to confirm the actual wheel width and inspect for any past wheel, suspension, or ride-height changes before choosing one construction over the other.
Choosing the Right Tire
What should I consider when choosing a 560-15 tire for a 1960 Fairthorpe Electron?
Start with the fact that 560-15 is the bias-ply fitment path for the 1960 Fairthorpe Electron. From there, the main comparison points are sidewall style, brand, tire series, rim-width suitability, and whether the goal is road use, traditional presentation, or a restoration-minded appearance rather than simply selecting any tire that shares the size code.
This size is available in blackwall, narrow whitewall, and wide whitewall versions from Firestone, US Royal, and Coker Classic, with a Pro-Trac front-runner option also present. Sidewall styling can change the entire visual character of a small sports car, so appearance matters here. Wheel width and the car's actual use should guide the final choice just as much as brand preference.
What sidewall styles are available for 1960 Fairthorpe Electron tires?
Sidewall choice depends on which size and construction you are considering. In 560-15 bias-ply, the 1960 Fairthorpe Electron has blackwall, narrow whitewall, and wide whitewall options. In 155R15 radial, the available products are blackwall tires, which gives the radial side of the fitment a more understated and distinctly European presentation.
That makes sidewall style one of the easiest ways to tune the car's look without changing wheel diameter. A blackwall generally keeps the appearance simple and sporting, while whitewall versions create a more formal or dressy period-style effect. Since the Electron is a compact specialty sports car, many owners weigh visual proportion carefully before deciding how much sidewall detail they want.
What brands offer tires for the 1960 Fairthorpe Electron?
Tires for the 1960 Fairthorpe Electron are available from Firestone, Michelin, Avon, Vredestein, US Royal, Coker Classic, and Pro-Trac. The brand mix depends on size and construction, with the 155R15 radial offerings concentrated among Firestone, Michelin, Avon, and Vredestein, while 560-15 bias-ply choices include Firestone, US Royal, Coker Classic, and Pro-Trac.
Brand alone should not decide the tire. The more useful comparison is which brand offers the construction, series, and sidewall treatment that match the way the car is being finished and driven. On this Electron, some buyers will prioritize a traditional bias-ply visual statement, while others will focus on a blackwall radial selection that still suits a 15-inch classic wheel.
Restoration & Appearance
Which tire should I choose for a period-style 1960 Fairthorpe Electron?
A period-style 1960 Fairthorpe Electron usually starts with the 560-15 bias-ply size because it preserves the traditional numeric sizing format and the visual character associated with earlier tire construction. Within that size, blackwall, narrow whitewall, and wide whitewall options create noticeably different presentations while staying within the same general fitment path.
The right choice depends on how strictly the car is being restored and the style the owner wants the finished vehicle to project. If exact historical accuracy matters, vehicle-specific reference photos, marque-club knowledge, and restoration documentation are worth checking before settling on a sidewall treatment. For many buyers, the goal is not absolute originality but a convincing period-style look that suits the car.
How does tire construction affect the appearance of a restored 1960 Fairthorpe Electron?
Tire construction changes the visual tone of a restored 1960 Fairthorpe Electron as much as the size itself. A 560-15 bias-ply tire gives the car a more traditional sidewall shape and opens the door to whitewall variations, while a 155R15 radial keeps the look more restrained with blackwall offerings and a later-style metric size designation.
That visual difference matters on a lightweight British sports car where the tires are a prominent part of the finished stance. A buyer trying to preserve a distinctly vintage look may stay with bias-ply or investigate a bias-look radial separately. Someone building a road-focused restoration may accept the radial appearance in exchange for the construction style they prefer to run.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1960 Fairthorpe Electron?
Yes, modifications can affect tire fitment on a 1960 Fairthorpe Electron even when the tire size itself is correct. Aftermarket wheels, different wheel widths, ride-height changes, suspension work, or body alterations can all change how a 560-15 or 155R15 tire sits in the wheel opening and how much steering or fender clearance remains.
That is why a classic car should be inspected as it exists today rather than assumed to match its original configuration. Check the actual wheel diameter and width first, then look at inner clearance, outer fender space, and turning clearance at full lock. A small specialty sports car can be more sensitive to these changes than a larger sedan or touring car.
What should I inspect before driving a 1960 Fairthorpe Electron on new tires?
Before driving a 1960 Fairthorpe Electron on new tires, inspect the wheels for correct diameter and condition, confirm that the tires are seated properly, and verify inflation pressure. It also makes sense to look over the steering and suspension components, since worn bushings, loose hardware, or alignment issues can undermine the benefit of fresh tires.
A short initial road test should include checking for rubbing, vibration, pull, or unusual response through the steering wheel. Collector cars that sit for long periods also deserve a close look at brake operation and wheel fastener security before normal road use. After the first miles, recheck pressure and take another look for any contact marks or signs of uneven seating.
How should 560-15 or 155R15 tires on a collector 1960 Fairthorpe Electron be maintained?
Maintenance for 560-15 or 155R15 tires on a collector 1960 Fairthorpe Electron starts with regular pressure checks and visual inspection, even if the car is driven sparingly. Tread depth is only part of the story on a low-mileage classic. Sidewall cracking, flat spotting from storage, cuts, bulges, and slow air loss are often more important than accumulated miles.
Storage conditions matter just as much as road use. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires over time. It is also wise to inspect the tires before every outing and especially before a longer drive, since an older collector vehicle may go weeks or months between trips and can develop issues while parked.
