1962 Fairthorpe Electron Tires

A 1962 Fairthorpe Electron uses either a 560-15 bias-ply tire or a 155R15 radial tire, both built for a 15-inch rim. Those are the two primary fitment paths associated with this model, and the Electron MK II is tied to both sizes rather than to one exclusive configuration.

The practical choice is less about finding an additional size and more about confirming which construction and wheel setup the car has now. A bias-ply 560-15 suits a more traditional vintage presentation, while a 155R15 follows a radial format. Wheel width, overall tire dimensions, and clearance should all be reviewed before switching from one setup to the other.

The tire sizes associated with the 1962 Fairthorpe Electron are built around a 15-inch rim diameter. Both the 560-15 bias-ply fitment and the 155R15 radial fitment share that same basic wheel diameter, which keeps the first fitment check fairly simple.

Rim diameter is only one part of the decision, though. It is still important to confirm actual wheel width before choosing among available tires, especially when considering a radial conversion or comparing different product series. A car that has been updated with replacement wheels should be measured directly rather than relying only on what would have been typical for the model.

560-15 is a numeric bias-ply tire size. In that format, the 560 refers to a nominal section width of about 5.60 inches, and the 15 identifies the wheel diameter in inches. On the 1962 Fairthorpe Electron, it represents the traditional bias-ply fitment path rather than a modern radial designation.

That matters because a 560-15 will not have the same construction character or sizing language as a 155R15 radial, even though both use a 15-inch rim. Owners choosing 560-15 usually compare sidewall appearance, brand, and intended presentation, then confirm wheel width and clearance so the selected tire matches the car’s current configuration.

On the 1962 Fairthorpe Electron, 560-15 is a bias-ply tire size. It uses a vintage numeric bias-ply format, and the available tires in that size follow that construction, with choices that include blackwall, narrow whitewall, and wide whitewall presentations.

That makes 560-15 the more traditional route for an owner who wants a classic small-sports-car look. A radial alternative does exist, but it should be treated as a separate fitment decision rather than the same tire in a different construction. Wheel width, dimensions, and intended road use should all be reviewed before changing from bias-ply to radial.

Radial equivalents for 560-15 include 155R15 and 560R15. The 155R15 is an 80-series metric radial equivalent, while 560R15 is a bias-look radial equivalent intended to keep a more traditional appearance than a conventional modern radial format.

Those options give the Fairthorpe owner two different radial directions to consider, but neither should be treated as automatic interchangeability. The recommended rim-width range for the equivalent setup is 4 to 5 inches, and the actual wheel, tire dimensions, and body clearance should be checked carefully before replacing a 560-15 bias-ply tire with either radial alternative.

A bias-look radial can be considered for a 1962 Fairthorpe Electron because 560R15 is available as a radial equivalent to the original 560-15 size. Its role is to offer radial construction while preserving a tire presentation that stays closer to a vintage bias-ply appearance.

That option can appeal to owners who want a more traditional visual style without staying with full bias-ply construction. Even so, the decision still requires careful fitment review. The wheel should fall within the appropriate rim-width range, and the tire’s overall dimensions and clearance should be checked against the car’s current setup before making the change.

Start with the two main decisions: construction and wheel compatibility. A 560-15 keeps the car in a vintage numeric bias-ply size, while 155R15 moves to a Euro-metric radial format. Both use a 15-inch rim, but they differ in presentation, available tire series, and the way the size is expressed.

From there, compare the product details that affect how the car will look and be used. Bias-ply options add blackwall and whitewall choices, while radial options bring several period-friendly blackwall series from Firestone, Michelin, Avon, and Vredestein. Wheel width, load figures where stated, and the car’s current suspension and clearance should guide the final decision.

Sidewall choice depends on the size and construction you select. In 560-15 bias-ply, available styles include blackwall, narrow whitewall, and wide whitewall. In 155R15 radial, the available products are blackwall tires, which gives the radial path a more restrained and sporting appearance.

That difference matters because sidewall style changes the car’s visual character even when the wheel diameter stays the same. A blackwall often suits a simple sports-car presentation, while narrow or wide whitewalls create a more styled vintage look. The best choice is the one that matches the car’s restoration direction and the owner’s preferred overall appearance.

The 1962 Fairthorpe Electron has tire options from several brands across its two fitment paths. Radial choices in 155R15 include Firestone, Michelin, Avon, and Vredestein. Bias-ply choices in 560-15 include Firestone, US Royal, Coker Classic, and Pro-Trac.

Brand matters mainly because it often goes hand in hand with tire series, sidewall style, and rim-width specifications rather than because one name should automatically be preferred. The smartest comparison is within the correct size first, then across the details that fit the car’s goals, whether that means a traditional whitewall bias-ply look or a blackwall radial setup.

For a period-style 1962 Fairthorpe Electron, the 560-15 bias-ply size is the natural starting point because it keeps the car in a vintage numeric bias-ply format. Within that size, blackwall, narrow whitewall, and wide whitewall options create different visual effects while staying within the traditional construction type associated with this fitment path.

The right appearance choice depends on the specific presentation the car is meant to have. Some owners want a simple sporting look, while others prefer a more decorative early-1960s sidewall treatment. When exact originality matters, it is wise to compare the chosen tire against marque-club guidance, period photography, or restoration documentation for the particular car.

Tire construction changes more than road feel on a restored 1962 Fairthorpe Electron; it also changes the car’s visual character. A 560-15 bias-ply keeps a traditional vintage format and opens the door to whitewall or blackwall styling, while a 155R15 radial presents a more modernized sizing convention and, here, a blackwall-only appearance.

That means the construction choice is part of the restoration decision, not just a technical one. Owners preserving a stronger period look often begin with the bias-ply route, while those prioritizing radial construction may accept a different visual presentation. Either way, the tire should complement the car’s wheels, stance, and intended era-correct feel rather than fight against them.

Yes, modifications can affect tire fitment on a 1962 Fairthorpe Electron even when the tire size itself is correct on paper. Aftermarket wheels, altered wheel widths, suspension changes, ride-height adjustments, or body modifications can all change how a 560-15 or 155R15 tire sits in the wheel opening and clears the steering and suspension.

That is especially important on a small, lightweight sports car where space can be limited. A Fairthorpe that has been changed from its original setup should be checked directly for wheel diameter, wheel width, clearance at full steering lock, and any signs of rubbing. Tire selection should follow the actual car in front of you, not assumptions about a standard configuration.

Before driving a 1962 Fairthorpe Electron on new tires, inspect the wheels, valve stems, and overall mounting condition, then confirm the tires are inflated correctly for the chosen setup. It is also smart to look at suspension and steering components, especially on a collector car that may spend long periods off the road.

A careful walk-around should include checking for sidewall damage, unusual bulges, cuts, irregular seating on the rim, and any immediate air loss after installation. On the first road test, listen for rubbing and pay attention to steering feel and straight-line tracking. A short reinspection after a few miles can catch clearance or pressure issues before they become larger problems.

Collector-car tires on a 1962 Fairthorpe Electron should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Whether the car runs 560-15 bias-ply tires or 155R15 radials, it is important to watch for cracking, flat spotting from long storage, tread wear changes, and slow air loss.

Low annual mileage does not eliminate tire aging, so condition matters as much as tread depth on a lightly used Fairthorpe. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the sidewalls. Periodic inspection of alignment, wheel condition, and suspension wear also helps the tires wear evenly and run more confidently on the road.
