1964 DAF Tire Fitment Guide

1964 DAF vehicles in this range use two sizes: 145R13 and 520-13, and both apply to the 1964 DAF Daffodil. Each size mounts on a 13-inch wheel, but they represent two different tire eras and constructions. The 145R13 is a radial, while the 520-13 is a bias-ply size. Rim-width guidance is available on some products, including 4.00 to 5.00 inches for one 145R13 radial and 3.5 or 3.50 to 4.00 inches on some 520-13 bias-ply offerings.

That means the first step is not choosing between different DAF models, but deciding whether your car should wear a radial or a bias-ply tire. If you want a more period-authentic presentation, the 520-13 is the natural place to start. If you want the small-car radial format that became familiar on later compact European cars, the 145R13 may be the better match. Always compare the tire choice to the wheel actually on the car before making a final decision.

On a 1964 DAF, 520-13 is a numeric bias-ply tire size. The 5.20 portion refers to the nominal section width in inches, and the 13 indicates the wheel diameter in inches. This older style of sizing does not communicate the same kind of aspect-ratio information modern metric sizes do, because it belongs to an earlier bias-ply naming convention.

For a Daffodil owner, that usually signals a more traditional look and construction. It is the size family most closely associated with period small-car tire styling, especially when paired with blackwall or narrow whitewall sidewall treatments. If your car is being restored with visual authenticity in mind, understanding that 520-13 is an older bias-ply format helps you separate appearance-driven choices from more modern radial alternatives that share the same wheel diameter.

On a 1964 DAF, 145R13 is a Euro-metric radial size. The 145 is the nominal section width in millimeters, the R identifies radial construction, and the 13 is the rim diameter in inches. In this older metric style, no aspect ratio is written into the size code, and it is conventionally understood as an 80-series type radial profile.

That makes 145R13 easy to recognize as the more modern-format choice of the two available sizes for the Daffodil. It keeps the correct 13-inch wheel diameter while moving to radial construction and a metric width convention. If you are comparing tires for a car that will be driven more often, this size often appeals to owners who want a tire format associated with later European compact-car road use rather than an earlier numeric bias-ply presentation.

For a 1964 DAF Daffodil, the choice between 145R13 and 520-13 is mainly a choice between radial and bias-ply construction, since both fit 13-inch wheels. The 145R13 is the radial option, while the 520-13 is the numeric bias-ply option. That means the decision is usually driven by how original you want the car to look and feel, rather than by a difference in model-specific fitment.

Owners restoring a Daffodil for a more era-authentic appearance often gravitate toward 520-13, especially when a traditional sidewall style matters. Owners who plan to use the car more regularly on modern roads often start with 145R13 because it keeps the same wheel diameter while moving to radial construction. The best choice depends on the character you want from the car, so settle the restoration-versus-driving question first and then confirm wheel width and product details.

1964 DAF tires come in more than one sidewall style. The 145R13 radial choices are blackwall, while the 520-13 bias-ply range includes blackwall and narrow whitewall versions. That spread gives Daffodil owners the option of a plain, understated look or a brighter period accessory style, depending on which tire family they choose.

For most European economy-car restorations of the mid-1960s, blackwall tends to look the most natural and factory-minded. Narrow whitewalls usually read as more customized or more style-driven, which may suit a car built for visual flair rather than strict originality. If your goal is authenticity for judging or marque-correct presentation, start by matching the sidewall treatment to period photos and club guidance, then narrow the choice by construction type.

Three brands cover 1964 DAF tire applications here: Michelin, Firestone, and Premium Sport. The 145R13 radial is available from Michelin and Firestone, while the 520-13 bias-ply is available from Firestone and Premium Sport. That gives the Daffodil owner a mix of traditional American reproduction-style offerings and a recognizable European brand presence in the radial size.

Brand choice matters most after you settle on size and construction. If you are focused on the radial 145R13, the decision stays within blackwall tires and may involve differences such as speed marking and rim-width publication. If you are shopping 520-13, the bigger visual distinction is often sidewall treatment, since that size includes both blackwall and narrow whitewall options. Treat the brand decision as the final refinement, not the starting point.

Rim-width guidance for 1964 DAF tires varies by size and sometimes by product. In 145R13, one radial product is approved for 4.00 to 5.00-inch rims. In 520-13, one bias-ply product fits a 3.5-inch rim and another fits a 3.50 to 4.00-inch rim. All of these tires share a 13-inch rim diameter, but that does not make every wheel width equally suitable for every tire.

The practical takeaway is to verify both wheel diameter and wheel width on the car before choosing between the two sizes. A Daffodil owner comparing radial and bias-ply options should not assume that any 13-inch wheel is automatically correct for either tire. Measuring the wheel and comparing it to the tire's approved range is the safest way to avoid poor fit, odd sidewall shape, or a mismatch between the tire and the wheel already on the car.

Inner-tube requirements on 1964 DAF tires depend on the exact product. The Michelin 145R13 carries a TL marking, which identifies it as tubeless, while the Firestone 145R13 uses a plain size marking. The 520-13 bias-ply products do not all carry the same tube notation in their size markings, so tube status can vary by product rather than staying uniform across the whole size.

That makes it important to check the sidewall marking and the wheel type before finalizing your setup. Some original wheels and some reproduction tires are happiest with a tube, while others are intended for tubeless use. If your Daffodil still has its original wheels, inspect their condition carefully and match the tire's tube recommendation to the wheel's design and sealing condition rather than assuming one rule applies to every 13-inch tire in this year and make.

Both 145R13 and 520-13 for a 1964 DAF Daffodil use a 13-inch rim diameter, so they share the same basic wheel diameter requirement. That means an original Daffodil wheel can often accept either size from a diameter standpoint. The more important difference is wheel width, because published rim-width guidance is not identical across the radial and bias-ply choices.

A wheel that physically takes one tire may still be a better match for one construction than the other. Before switching from 520-13 to 145R13, or vice versa, measure the wheel and compare it to the approved width range for the specific tire you are considering. That extra check is especially worthwhile on a small car like the Daffodil, where wheel and tire proportions strongly affect both appearance and the way the tire sits on the rim.

A 1964 DAF should be stored with the tires clean, properly inflated, and protected from sunlight, electric motors, ozone sources, and standing moisture. If the car will sit for long stretches, move it periodically or support it in a way that reduces prolonged loading on one contact patch. Bias-ply tires such as 520-13 are generally more prone to flat-spotting during storage than radial tires such as 145R13.

That matters because a Daffodil is light enough that storage damage can sneak up as age-related hardening rather than obvious wear. If the car is kept indoors, keep it away from welders, compressors, and other equipment that creates ozone. If it is kept on the ground, rotate its resting position every few weeks when possible. Storage habits often preserve collector tires more effectively than low mileage alone, especially on cars that are driven only seasonally.

Tires on a 1964 DAF should be judged more by age than by mileage. A good collector-car rule is to begin paying close attention once a tire reaches the five-to-seven-year range and to treat around ten years as a point where replacement deserves serious consideration, even if tread depth still looks acceptable. The DOT date code on the tire is the starting point for that age check.

A Daffodil often covers limited annual miles, so a tire can appear fresh while still aging out structurally. Heat cycles, storage conditions, inflation habits, and exposure to sunlight all affect service life. Because these cars are usually preserved rather than worn out through commuting mileage, keeping a record of installation date and date code is more useful than relying on tread wear alone. Age, not appearance, is often the deciding factor on a lightly used classic.

Tires on a 1964 DAF should be inspected before every drive and again before any longer outing. Check for sidewall cracking, weathering, cuts, bulges, uneven tread wear, and pressure loss. If your Daffodil uses a tube-type setup, valve stems and any signs of slow leakage deserve just as much attention as the tread and sidewalls.

Frequent inspection matters on a small, lightly powered car because age-related tire problems can affect confidence and stability long before they become dramatic failures. A quick walk-around before a local drive is good practice, and a more thorough check before a touring event is even better. Pay special attention after long storage periods, because that is when flat spots, pressure loss, and visible cracking often make themselves known for the first time.

For a 1964 DAF Daffodil, bias-ply construction is the most era-typical starting point when thinking about original-style fitment, and the available 520-13 bias-ply size aligns with that period character. The 145R13 radial reflects a later-format small-car tire approach and is better understood as an alternative choice than as the most likely original-style default. Original equipment brand should be confirmed through period DAF literature or marque-specific sources rather than assumed.

That means a restoration aimed at factory character usually begins by examining whether a 520-13 bias-ply blackwall best matches the car's intended presentation. If your goal is a historically faithful result, compare the tire size, construction, and sidewall look against owner manuals, brochures, and knowledgeable DAF clubs. Market differences, replacement history, and wheel changes over the car's life can all affect what appears to be "original," so verify before treating any one tire as universally correct.

Correct tire fitment matters on a 1964 DAF because show judging often pays attention to size, construction, and sidewall appearance. A radial tire can look noticeably different from a bias-ply tire even when both fit the same 13-inch wheel, and a narrow whitewall can send a different visual message than a plain blackwall. Those differences may be acceptable at casual shows but draw closer scrutiny in authenticity-focused events.

If your Daffodil will be judged, match the tire not only to the car but also to the event standard. Some venues reward a broadly period-correct presentation, while others expect market- and model-specific details. That is why marque clubs and period photography are so valuable: they help you decide whether the right answer is a plain 520-13 bias-ply, a blackwall radial alternative, or a more style-conscious whitewall treatment. Tire choice is part of the car's visual story, not an afterthought.

For a 1964 DAF in 145R13, the Michelin XAS FF and Firestone F560 Radial are both blackwall radial choices, but their published details are not identical. The Michelin carries a 145HR13 74H TL marking, which includes an H speed rating and a tubeless designation, and it weighs 18 pounds. The Firestone F560 Radial uses a 145R13 marking, weighs 12.7 pounds, and includes a published rim-width range of 4.00 to 5.00 inches plus a load figure of 825 pounds at 44 psi.

Those differences make the comparison less about whether one is "right" and more about which details matter to you. The Michelin brings a clearly stated speed symbol and tubeless marking, while the Firestone supplies more published fitment guidance on rim width and a lighter weight. If you are choosing between the two for a Daffodil, compare the wheel on the car, the kind of road use you expect, and whether the sidewall marking itself matters to your restoration or driving priorities.

1964 DAF tires can be suitable for highway driving when they are the correct size, properly fitted, correctly inflated, and in sound age condition. In the 145R13 radial range, one Michelin option carries an H speed rating, which corresponds to 130 mph, while another radial product uses a plain 145R13 marking without a published speed letter in the size string. The 520-13 bias-ply choices do not show modern speed symbols in the same way.

In real use, a Daffodil's mechanical design, braking capability, suspension condition, and overall vintage-car limitations matter at least as much as the tire's nominal speed capability. A healthy radial may feel more at home in sustained modern traffic, while a bias-ply setup asks for more period-minded expectations. Highway safety starts with the whole car, so treat tire choice as one part of a complete roadworthiness check rather than the only deciding factor.

Inflation pressure on 1964 DAF tires should not be guessed from one tire size and transferred to another. Published load-and-pressure figures include 825 pounds at 44 psi for one 145R13 radial, 770 pounds at 32 psi for one 520-13 bias-ply, and 1100 pounds at 60 psi for one Premium Sport 520-13 version. Those figures describe the tire's rated capacity point, not automatically the pressure your Daffodil should run in everyday service.

Use the original DAF owner's literature as the first guide for vehicle pressure, then compare that recommendation with the tire manufacturer's guidance for the exact reproduction or replacement tire you have chosen. Small vintage cars can be sensitive to overinflation or underinflation, especially when changing construction type. The right pressure is the one appropriate to the car, the tire, and the intended use, not simply the highest pressure molded or published for the tire itself.

Before a longer drive in a 1964 DAF, inspect every tire for cracks, cuts, bulges, tread wear, and proper inflation. Confirm that each tire is the same intended size and construction, check the age of the tires, and inspect the spare as carefully as the four on the ground. If your setup uses tubes, pay close attention to valve stems and any sign of slow leakage or chafing-related problems.

That tire check should sit alongside a broader vintage-car inspection that includes brakes, steering, wheel bearings, fluid levels, lights, and charging health. A Daffodil is a small, charming classic, but its age means long drives reward preparation. Even if the car has been running well locally, sustained speeds and heat can reveal old issues quickly. A careful pre-drive inspection is the best way to keep a pleasant outing from turning into an avoidable roadside problem.
