1961 Holden Tire Fitment Guide

1961 Holden vehicles use two tire sizes: 175R13 and 640-13. Both sizes apply to the 1961 Holden FB and 1961 Holden EK, and both mount on 13-inch wheels. The 640-13 bias-ply tire has a confirmed rim width range of 4.00 to 4.50 inches, while the radial option should still be matched carefully to the actual wheel before final selection.

That means most buyers do not need to sort out model-specific sizing first, because FB and EK share the same basic fitment. The more important choice is whether your Holden is being restored with an emphasis on period appearance or prepared for regular road use with radial construction. Checking the wheel width and the tire size already on the car is the best first step before moving deeper into model or product selection.

On a 1961 Holden tire, 640-13 is a numeric bias-ply size. The 6.40 figure refers to the nominal section width in inches, and the 13 refers to the wheel diameter in inches. That format belongs to the bias-ply era and is exactly the kind of sizing a buyer expects to see on an early-1960s Holden restoration.

A 640-13 is the size to focus on if your goal is a more authentic vintage look and a tire construction that matches the period character of the car. It also matters for wheel fit, because the available 640-13 product is intended for 4.00- to 4.50-inch-wide rims. If your Holden still wears original-style narrow steel wheels, this is often the size that makes the most visual and historical sense.

On a 1961 Holden tire, 175R13 is a Euro-metric radial size. The 175 is the section width in millimeters, the R indicates radial construction, and the 13 is the wheel diameter in inches. Because no aspect ratio is printed, this type of size is conventionally treated as an 80-series radial format.

That makes 175R13 the more modern-looking size code, even though it still fits the same 13-inch wheel diameter used by the FB and EK. Buyers often end up here when they want to keep the car on a stock wheel diameter but move away from the feel of a bias-ply tire. It is still worth confirming the actual wheel width and overall stance you want before making the switch.

For a 1961 Holden, the choice between 175R13 and 640-13 is mainly a choice between radial and bias-ply construction rather than a difference between FB and EK fitment. Both sizes fit the same 13-inch wheel diameter across the model range. The 640-13 is the more period-correct route for an early-1960s presentation, while the 175R13 is the radial alternative for owners who prefer a more modern tire format.

That decision usually comes down to how the car will be used and how closely you want it to reflect its original era. A show-focused restoration often leans toward the numeric bias-ply size, especially when a wide whitewall look matters. A driver that sees more regular road miles may point you toward the radial size, but wheel width, appearance, and the tire already on the car should still be checked before you commit.

1961 Holden tires in 640-13 are available in a Wide Whitewall style from BFGoodrich. That sidewall treatment is visually appropriate for many early-1960s family cars and gives an FB or EK the bright, era-correct appearance many restorers want. The radial 175R13 fitment is part of the same overall size coverage for these cars, but sidewall choice depends on the individual tire built in that size.

For a restored Holden that is being judged on presentation, sidewall style can matter almost as much as the size itself because it strongly affects the car’s stance and period impression. A wide whitewall tends to suit stock or faithfully restored cars, while a more understated sidewall may fit a driver or mild custom better. If authenticity is important, compare the look you want with period photos and club knowledge before choosing.

BFGoodrich makes a 640-13 tire for 1961 Holden vehicles, offered as a Silvertown Classic Bias Ply with a 2.25-inch whitewall. That brand has long-standing historical credibility in the vintage tire world and fits naturally with the kind of bias-ply presentation many FB and EK owners want. The radial 175R13 fitment remains part of the tire coverage for these Holdens, but brand selection depends on the exact tire built in that size.

Brand choice is only one part of the decision for a 1961 Holden. Construction type, sidewall styling, and how close you want the car to feel and look to its original era usually matter more than the badge on the sidewall alone. Once you know whether you want the radial or the numeric bias-ply path, it becomes much easier to narrow the field to the tire that suits your Holden’s intended use.

For 1961 Holden vehicles, the confirmed rim width range is 4.00 to 4.50 inches for the 640-13 bias-ply tire, and that size mounts on a 13-inch rim. The 175R13 radial also uses a 13-inch rim diameter, so diameter compatibility is shared across both Holden FB and EK applications. Wheel width still needs to be checked against the exact tire chosen before installation.

This matters because a tire can match the wheel diameter and still be a poor choice if the wheel is too narrow or too wide for that casing. Original Holden steel wheels are often part of the restoration, so measuring what is actually on the car is worth the effort. If your wheels have been changed at some point in the car’s life, confirm width directly rather than assuming they remain stock.

Original 1961 Holden wheels can often be used with both tire sizes because 175R13 and 640-13 both fit a 13-inch rim diameter. That shared diameter is true for both the 1961 Holden FB and 1961 Holden EK. The point that still needs confirmation is wheel width, since the available 640-13 bias-ply tire is intended for 4.00- to 4.50-inch rims.

For many owners, this shared 13-inch fitment is what makes changing between radial and bias-ply practical without changing the basic wheel format of the car. It does not mean every 13-inch wheel is automatically suitable for every tire construction or profile. Before mounting a new set, measure the wheels, inspect them for age and condition, and confirm that the tire you prefer is appropriate for the rim actually on your Holden.

A 1961 Holden should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age sidewalls. Keep the tires properly inflated, and move the car periodically if it sits for long stretches. Bias-ply tires such as 640-13 are more prone to flat-spotting during long static storage than a radial typically is.

That matters on an FB or EK because collector cars often spend far more time parked than driven. If the Holden will be off the road for a season, many owners either roll the car occasionally or use stands to reduce the stress on the casing. Clean, dry floors and avoiding petroleum contamination around the tires also help preserve the rubber and keep the car ready for the next outing.

Tires on a 1961 Holden are usually judged more by age than by mileage, because collector cars often accumulate very few miles each year. A good rule is to begin evaluating them closely after about five to seven years and to treat roughly ten years as a serious replacement point regardless of remaining tread. The DOT date code on the tire helps establish that timeline.

A lightly used FB or EK can still have aged-out tires even when the tread looks deep and the car seems to drive normally. Sidewall cracking, hardening rubber, repeated pressure loss, and long-term storage all matter more than odometer readings in this kind of vehicle. If the tires came with the car and their age is unclear, checking the date code is one of the most valuable first steps you can take.

Tires on a 1961 Holden should be inspected before every drive and again before any longer highway outing. Look for sidewall cracking, cuts, bulges, uneven wear, and signs that the tire is losing pressure over time. If your Holden runs a tube-type setup, the condition of the valve stems and the wheel’s interior surface also deserve attention.

Short local drives can hide problems that become much more serious once the car is hot and moving at sustained road speed. An FB or EK that has sat for weeks or months should not simply be started and driven away without a quick walk-around. A two-minute inspection before each trip is a simple habit that protects the tire, the wheel, and the rest of the car.

A 1961 Holden EK would originally be associated with bias-ply construction rather than a modern radial, because bias-ply tires were still the standard type for mainstream passenger cars of that era. Within the fitments used across 1961 Holden vehicles, 640-13 is the period-style size and format that aligns most closely with that original character. Original-equipment branding could vary by market and delivery details, so the safest reference points are factory literature and Holden marque specialists.

For a restoration, the takeaway is that size format, construction, and sidewall appearance all matter if you want the car to look right. A radial may be a sensible road-going choice, but it changes the visual and historical impression compared with a numeric bias-ply tire. If your EK is being prepared for a judged event, check the standards used by the club or show before making your final decision.

Correct tire fitment absolutely matters when showing a 1961 Holden, especially if the car is entered in stock or authenticity-focused classes. Judges and knowledgeable enthusiasts often notice whether the size format, construction type, and sidewall treatment suit the era of the vehicle. On an early-1960s Holden, a numeric bias-ply tire with an appropriate whitewall presentation will usually read more authentic than a modern-looking radial.

That does not mean every show requires the same standard, because some events favor preservation, some favor period-correct restoration, and others welcome tasteful driver upgrades. A car built to be driven regularly may still wear a radial without issue outside strict authenticity judging. If trophies or marque-club standards matter to you, confirm those expectations before the tires go on the car rather than after the judging sheet comes back.

A 1961 Holden FB would have been associated with bias-ply tires in period, not with the later radial format that many owners consider today. Among the sizes used for 1961 Holden vehicles, 640-13 is the size that matches that early-1960s bias-ply format and appearance most closely. Brand choice at new-car delivery could vary, so originality work should focus first on construction type, size format, and sidewall style before chasing a specific brand name.

That makes the 640-13 the natural starting point for an FB restoration where factory character matters. The radial 175R13 still fits the same 13-inch wheel diameter, but it changes the visual language of the car and the way the size is expressed on the sidewall. If your FB is being restored to a particular market version or club standard, period photos and marque research are worth consulting before you settle on a tire.

1961 Holden tires can be suitable for highway driving when they are in good condition, correctly inflated, and matched to the way the car is used. The available 640-13 bias-ply product carries an S speed rating, which corresponds to a 112 mph ceiling, well beyond the normal highway pace of a stock FB or EK. In real use, the condition of the tire and the Holden’s own brakes, suspension, steering, and age-related mechanical health are usually more limiting than the speed symbol itself.

The practical question is not whether a reproduction collector tire can survive highway speed in theory, but whether the whole car is ready for sustained road use. A fresh, properly fitted tire on a sorted Holden is very different from an old tire on a car that has sat for years. Before longer drives, inspect the tires carefully and treat the rest of the chassis with the same seriousness.

Inflation pressure on a 1961 Holden should be set with the specific tire and the car’s intended use in mind, not by copying a number from a different size. The available 640-13 BFGoodrich bias-ply tire carries a maximum load of 1,045 pounds at 32 psi, which is the tire’s rated pressure reference point rather than a universal instruction for every Holden tire. Factory pressures for an FB or EK are best confirmed through the owner’s manual or period service information.

That distinction matters because vehicle makers often specified operating pressures lower than a tire’s maximum rated figure, especially on lighter classic cars. If you are moving between radial and bias-ply constructions, do not assume they should be run the same way. Start with the vehicle guidance, confirm the tire manufacturer’s recommendations for the exact product, and adjust only within safe published limits.

Before taking a 1961 Holden on a longer drive, inspect each tire for cracks, cuts, bulges, embedded debris, uneven wear, and pressure loss, and make sure the spare is usable as well. Check valve stems, wheel condition, and tread depth, and pay extra attention to any tire that has been sitting under load for a long period. On an older Holden, the tires are only one part of the equation, so brakes, cooling, steering, and fluids should be part of the same pre-trip routine.

That kind of inspection is especially important on cars like the FB and EK because they are often driven occasionally rather than daily. A tire that looks acceptable in the garage can reveal age-related issues once heat and speed build on the road. A careful pre-drive check takes very little time and gives you a much clearer idea of whether the Holden is ready for a relaxed local run or a longer day behind the wheel.
