1962 Holden EK Tires

The 1962 Holden EK is associated with two tire sizes: 640-13 in a bias-ply construction and 175R13 in a radial format. Both sizes use a 13-inch rim diameter, but they represent different sizing systems and different approaches to how the car is set up for appearance and road use.

For many owners, the real choice is whether to keep the traditional 640-13 bias-ply fitment or consider a radial-size alternative such as 175R13. Before selecting either one, check the actual wheels on the car, especially if it has been modified over the years, and make sure the tire's dimensions and construction suit the EK's intended use.

The tire sizes associated with the 1962 Holden EK use a 13-inch rim diameter. That applies to both the vintage 640-13 bias-ply size and the 175R13 radial format, so the wheel diameter itself remains consistent even though the tire constructions and sizing conventions differ.

Rim diameter is only part of the fitment picture. Wheel width also matters, especially if the car has replacement wheels or if a radial equivalent is being considered in place of the older bias-ply size. A quick check of the actual wheel dimensions helps avoid clearance issues and keeps the tire choice aligned with the EK's overall setup.

Yes. The 1962 Holden EK Base is associated with the same two fitment paths found on this model: 640-13 in bias-ply form and 175R13 in radial form. That makes the Base model straightforward from a size standpoint, with no separate rim diameter change to sort out first.

Even with shared fitment, the right choice still depends on how the car is being used and presented. A restoration-oriented EK Base may stay with the traditional bias-ply size, while a driver-focused car may be evaluated around the radial alternative. Verifying the actual wheels and the car's current stance remains worthwhile before making the final tire selection.

For the 1962 Holden EK, 640-13 is the bias-ply tire size. It uses the older numeric sizing system rather than modern metric radial sizing, which is why it looks different on paper from 175R13 even though both relate to the same 13-inch wheel diameter.

That distinction matters because a bias-ply tire influences both appearance and setup decisions. Owners keeping a period-style presentation often begin with 640-13, while those considering a radial conversion should evaluate the available equivalents instead of assuming the older size behaves the same way as a radial. Wheel width, clearance, and intended road use all deserve a careful look.

Radial equivalents for 640-13 include 175R13 as an 80-series metric radial, P175/75R13 as a 75-series P-metric radial, and P185/70R13 as a 70-series P-metric radial. A 650R13 bias-look radial is also available for buyers who want a radial construction while keeping a more traditional visual impression.

Those choices give the 1962 Holden EK owner several ways to move from an older bias-ply size into radial sizing, but they are not automatic substitutions. The recommended rim-width range tied to the equivalency set is 4 to 6 inches, and final selection should be checked against the actual wheel width, tire dimensions, and available clearance on the car.

Start by confirming the wheel diameter and width, since the 1962 Holden EK keeps a 13-inch rim but radial equivalents for 640-13 should still be matched to an appropriate wheel. Then compare the intended radial size, such as 175R13 or another listed equivalent, against the car's available clearance and current wheel setup.

Construction changes can also affect the overall character of the car, so the decision should match the EK's purpose. A restoration-focused car may favor the look of a bias-ply or a bias-look radial, while a driver may lean toward conventional radial sizing. Checking suspension condition, steering clearance, and fender space helps avoid surprises once the new tires are installed.

Begin with the role the car is meant to serve. A 640-13 tire keeps the 1962 Holden EK in its traditional bias-ply sizing format, so the choice usually revolves around maintaining a period-style stance and sidewall presentation rather than moving into a modern radial specification.

After size is confirmed, look at details that shape how the tire suits the car, including sidewall style, rim-width compatibility, load figure, and overall visual character. The available 640-13 product here uses a wide whitewall and a classic bias-ply series, which makes it especially relevant for owners pursuing a more restoration-oriented appearance.

Among the available products associated with the 1962 Holden EK, the sidewall style shown in 640-13 is a wide whitewall. That style gives the car a distinctly early-1960s look and is a strong visual factor for owners who want the tire to contribute as much to the EK's presentation as to its basic fitment.

Sidewall choice should follow the overall character of the car rather than being treated as a minor cosmetic detail. A wide whitewall can suit a restoration-oriented build or a traditional street presentation, while owners pursuing a more understated look may focus first on whether they want bias-ply or radial construction before narrowing the sidewall treatment.

BFGoodrich is represented in the available 640-13 fitment for the 1962 Holden EK. The product shown is part of the Silvertown Classic Bias Ply line, which keeps the emphasis on a traditional bias-ply construction and a vintage-style appearance suited to an early-1960s Holden.

Brand matters most when it intersects with the exact size, construction, and appearance you want. Instead of treating brand alone as the deciding factor, compare whether the tire matches the EK's intended use, the wheel dimensions on the car, and the sidewall presentation you want. That approach usually leads to a better-informed choice than choosing on name alone.

A period-style 1962 Holden EK usually starts with the 640-13 bias-ply size rather than a modern radial format. That older numeric sizing system suits the car's era and preserves the traditional tire profile that many owners want when the goal is to keep the EK visually aligned with its early-1960s character.

The final choice depends on how strictly the car is being restored and how it will be driven. A wide-whitewall bias-ply can support a strong vintage presentation, but exact originality questions should be checked against marque-club guidance, period photos, or vehicle-specific historical references. That is especially important when appearance details matter as much as mechanical fitment.

Tire construction changes more than ride feel on a restored 1962 Holden EK; it also changes the car's visual impression. A 640-13 bias-ply keeps the older sizing language and traditional look associated with the car's era, while a radial such as 175R13 moves the presentation toward a more modern tire format.

That difference becomes more noticeable when sidewall style is part of the build theme. A wide whitewall on a bias-ply tire emphasizes a classic early-1960s appearance, while a radial conversion generally shifts the car away from that original-era look. Matching construction to the restoration goal helps the EK look intentional rather than visually mixed.

Yes. Even though the 1962 Holden EK is associated with 13-inch tire fitments, modifications can change what actually works on the car. Aftermarket wheels, altered wheel widths, suspension changes, brake conversions, or body modifications can all affect whether a chosen 640-13 or 175R13 setup clears properly.

A careful inspection is worthwhile before replacing tires, especially on older cars that may have changed hands several times. Check the actual wheel dimensions, look for rubbing marks around fenders and steering components, and confirm that the car sits as expected at normal ride height. Those steps matter more than assuming the car still matches its original wheel and tire configuration.

Before putting a 1962 Holden EK back into regular road use on new tires, inspect the wheels, valve stems, lug hardware, and overall tire clearance at both straight-ahead and turned steering positions. It is also smart to confirm that the tires are inflated properly for the chosen setup and that no suspension or steering parts show obvious looseness.

On a collector-era car, the condition of the rest of the chassis matters almost as much as the new tires themselves. Look for worn bushings, sagging springs, wheel-bearing play, and any signs of contact between the tire and body or suspension. A short, careful test drive followed by a second visual check can reveal issues before they become larger problems.

640-13 tires on a collector 1962 Holden EK should be maintained with regular pressure checks, periodic visual inspections, and attention to age-related condition. Even low-mileage cars need monitoring because time, storage conditions, and infrequent use can affect a tire long before the tread looks worn.

Watch for cracking, bulges, cuts, uneven wear, and slow air loss, and keep the car stored away from prolonged heat, direct sunlight, and ozone sources when possible. It also helps to move the car occasionally so the tires are not sitting under load in one position for long periods. Any sign of deterioration deserves prompt evaluation before further road use.
