1961 Lloyd Tire Fitment Guide

1961 Lloyd vehicles use five distinct tire sizes, and each size is tied to a specific model. The Alexander uses 4.25-15 on a 15-inch rim. The Arabella uses either 145R13 radial or 520-13 bias-ply on 13-inch rims. The LT uses either 155R13 radial or 560-13 bias-ply on 13-inch rims. Rim width guidance appears on some products: 145R13 fits 4.00 to 5.00 inches, 155R13 fits 4.00 to 5.50 inches, 520-13 appears on 3.5-inch and 3.50 to 4.00-inch applications, and 560-13 appears on 3.50 to 4.50-inch applications depending on the tire.

That means a 1961 Lloyd owner should start with model identification, not just year and make. Alexander owners need the dedicated 15-inch size, while Arabella and LT owners may be choosing between a bias-ply size and a radial size on the same 13-inch wheel diameter. Before ordering, compare the actual wheel on the car to the tire's approved rim-width range, especially if the wheels may have been changed during an earlier restoration or regular road use.

On a 1961 Lloyd, 4.25-15 is a traditional numeric bias-ply size. The 4.25 refers to the nominal section width in inches, and the 15 refers to the rim diameter in inches. That format belongs to the Alexander in this year, and it reflects older sizing practice used before metric radial designations became common on later small cars.

For an Alexander owner, the key point is that 4.25-15 is not interchangeable with the 13-inch Arabella or LT sizes. It belongs to a different wheel diameter and a different fitment family altogether. If your car is a small Lloyd and you are unsure whether it is an Alexander or a later, larger model, the wheel and tire size already on the car will usually point you in the right direction before you move on to choosing sidewall appearance or restoration style.

On a 1961 Lloyd, 145R13 and 155R13 are euro-metric radial sizes. The first number is the section width in millimeters, the R identifies radial construction, and the final number is the rim diameter in inches. When no aspect ratio is printed in this style, it is conventionally treated as an 80-series radial. The Arabella uses 145R13, while the LT uses 155R13.

That difference matters because the two radial sizes are not simply generic 13-inch substitutes for one another. They belong to different models and have different section widths, so an Arabella owner should stay with the Arabella size and an LT owner should stay with the LT size. If you are trying to sort out a car that has been converted from bias-ply to radial at some point in its life, confirming the model first will keep the radial choice on the right track.

For a 1961 Lloyd Arabella, the choice between 145R13 and 520-13 is mainly a radial-versus-bias-ply decision on the same 13-inch rim diameter. The 145R13 is a radial blackwall size available from Michelin and Firestone, while the 520-13 is a bias-ply size offered in blackwall and narrow whitewall versions from Firestone and Premium Sport. The radial path suits owners who want a later construction type, and the bias-ply path suits owners who want a more era-correct presentation.

Choose the Arabella tire that matches how you plan to use the car and how closely you want it to reflect early-1960s appearance. A show-focused restoration generally leans toward the bias-ply size, especially if whitewall styling is part of the look you want. A road-driven Arabella may point you toward the radial option. The important step is not to mix Arabella sizing with LT sizing simply because both cars use 13-inch wheels.

1961 Lloyd tires are available in several sidewall styles, but the choices depend on model and size. The radial sizes 145R13 and 155R13 come in blackwall form. The Arabella's 520-13 bias-ply size appears in blackwall and narrow whitewall versions. The LT's 560-13 bias-ply size appears in narrow whitewall and wide whitewall versions.

That gives 1961 Lloyd owners some flexibility in visual presentation without stepping outside the correct size family for the model. Blackwalls are a natural fit for many European small-car restorations, while narrow and wide whitewall choices can shift the car's personality toward a more stylized period look. If authenticity is important for judging or club display, match the sidewall style not just to the era, but to the market presentation and restoration theme of your specific car.

Several brands cover 1961 Lloyd fitments, and the brand mix changes by size. 145R13 is available from Michelin and Firestone. 520-13 is available from Firestone and Premium Sport. 155R13 is available from Michelin and Dunlop. 560-13 is available from BFGoodrich and Firestone. That spread gives owners a mix of traditional reproduction-style offerings and period-appropriate radial names depending on the model.

Brand choice should come after you confirm the correct model and size family. Once the fitment is right, compare sidewall style, rim-width compatibility, and any load or speed markings that matter for your intended use. A 1961 Lloyd used for club events and local cruising may call for a very different visual emphasis than one being driven more regularly, even when both cars wear the correct nominal size for the model.

Rim-width guidance for 1961 Lloyd tires depends on the size. The 145R13 radial fits 4.00 to 5.00-inch rims. The 155R13 radial fits 4.00 to 5.50-inch rims. The 520-13 bias-ply appears on 3.5-inch and 3.50 to 4.00-inch applications, depending on the tire. The 560-13 bias-ply fits either 3.50 to 4.00-inch or 4.00 to 4.50-inch rims, depending on the brand and version.

That variation is why wheel measurement matters before mounting a new set on a vintage Lloyd. Two tires with the same nominal size may not share the exact same approved rim-width span. Measure the wheel that is actually on the car rather than assuming it is original, especially on cars that may have seen earlier restorations, wheel swaps, or long service life where replacement parts were installed without preserving the original setup.

Tube use on 1961 Lloyd tires depends on the specific size and product. The 145R13 Michelin and Firestone radial products include tubeless configurations, and the 155R13 Michelin example is also marked tubeless. The bias-ply 520-13 and 560-13 products shown here do not carry a tubeless marking, so tube use should be confirmed against the exact tire and wheel combination before installation.

That matters because an older wheel may still require a tube even when a tire is capable of tubeless service, especially if the wheel design or condition is not ideal for a modern airtight seal. A restorer should inspect the wheel carefully, check the sidewall marking of the exact tire being mounted, and make tube decisions as part of the wheel-and-tire system rather than treating the tire alone as the whole answer.

On the 13-inch 1961 Lloyd models, the wheel diameter is compatible across each model's bias-ply and radial choice. The Arabella pairs 145R13 and 520-13 on 13-inch rims, and the LT pairs 155R13 and 560-13 on 13-inch rims. Diameter compatibility does not automatically mean every 13-inch wheel is ideal for every tire, because approved rim-width ranges still differ by size and, in some cases, by brand.

For that reason, an original 13-inch wheel can often remain in service when switching between the model's bias-ply and radial options, but only after confirming width and condition. This is especially important on small European cars, where narrow wheels are common and a later radial may call for a broader approved range than a traditional bias-ply tire. Measure first, then choose the tire that fits the wheel as well as the model.

A 1961 Lloyd 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 accelerate rubber aging. Keep the tires clean, maintain inflation, and move the car periodically so one section of the casing does not carry the load for months at a time. Bias-ply tires tend to flat-spot more readily during static storage, while all vintage tires are vulnerable to age-related sidewall cracking if the environment is harsh.

If the car will sit for an extended season, many collectors either roll it occasionally or use stands placed correctly under the chassis to reduce prolonged load on the tires. The goal is preservation, not just convenience. Small, lightly built cars like a 1961 Lloyd may not stress the tires with huge weight, but long inactivity still ages the rubber. Storage conditions often matter more to tire life than annual mileage on a collector car.

Tires on a 1961 Lloyd are usually judged by age and condition more than mileage. A good rule is to begin close inspection and evaluation around five to seven years, and to treat ten years as the point where replacement deserves serious consideration even if tread remains. The DOT date code on the tire identifies age, and visible cracking, hardening, or repeated air loss can justify replacement earlier.

That approach fits collector cars because many vintage Lloyds accumulate very few miles but spend long stretches parked. Low mileage can create a false sense of security when the rubber has already aged out. A car that still looks fresh in the garage may no longer be ready for touring, club events, or highway use. Tire age should be part of routine ownership records alongside fluid changes, brake service, and other time-based maintenance.

Tires on a 1961 Lloyd should be inspected before every drive and given a more deliberate inspection before any longer outing. Look for sidewall cracking, tread separation, cuts, embedded objects, uneven wear, and any sign of bulging or distortion. Check inflation at the same time, and if your setup uses tube-type construction, include the valve stems and the tube-related hardware in the inspection routine.

Frequent inspection is especially important on older cars because a tire problem may appear before the car has traveled enough miles to reveal it gradually. A short local cruise can hide issues that become serious once heat builds on a longer trip. Make the tire check part of your departure habit, along with verifying brakes, lights, and fluid levels. That routine is simple, fast, and far more valuable than waiting for wear patterns alone to tell the story.

A 1961 Lloyd Arabella was originally of the era when bias-ply construction was still the standard fitment on most small European cars, so the 520-13 bias-ply size aligns most closely with period-correct practice. The 145R13 radial size is a later-style construction choice within the correct model fitment family rather than the default early-1960s norm. No original equipment brand should be assumed without model-specific factory literature or marque-club confirmation.

For a restoration, that means size, construction, and sidewall appearance should all be considered together. A buyer pursuing authenticity would usually start with the bias-ply size and then refine the sidewall style to match the car's intended market character and show goals. If your Arabella has an unusual history, export-market details, or earlier modifications, a Lloyd specialist or marque club can help confirm what is most appropriate for that exact car.

Correct tire fitment matters on a 1961 Lloyd because judges and knowledgeable enthusiasts often notice tire size, construction type, and sidewall appearance very quickly. A bias-ply Lloyd wearing a period-appropriate size and sidewall style usually looks more authentic for concours-oriented presentation than the same car wearing a modern radial construction. Even when the wheel diameter is correct, an obviously different sidewall profile can change the stance and visual character of the car.

That does not mean every restored Lloyd must avoid radials, but it does mean the choice should match the purpose of the car. A touring car and a judged car often have different priorities. If the car will be shown in marque-specific events, ask the club or judging body what they expect before making a final decision. Event standards can vary, and getting the tire details right is often one of the simplest ways to strengthen authenticity.

For the 1961 Lloyd LT, the 560-13 bias-ply size is the most era-consistent starting point for an original-style restoration. The companion 155R13 size is a radial alternative within the LT fitment range, but radial construction was not the ordinary baseline on compact early-1960s cars. As with the Arabella, original equipment brand should be verified through factory literature or Lloyd marque sources rather than assumed from modern replacement offerings.

That makes the LT a good example of how correct fitment and restoration philosophy overlap. If you want the car to read as an authentic early-1960s Lloyd, the bias-ply size with an appropriate whitewall treatment may be the stronger visual match. If the car is restored for regular road use and authenticity is a secondary concern, the radial route remains within the LT's proper size family. The important part is keeping the choice within the LT's own 13-inch fitment options.

1961 Lloyd tires can be suitable for highway use when they are the correct size, in sound condition, and used within their speed and load limits. The radial 145R13 and 155R13 products here include H-rated examples, which carry a 130 mph ceiling. The bias-ply 520-13 and 560-13 options should be approached as traditional vintage-style tires rather than modern high-speed touring tires. On an early-1960s Lloyd, the car's own braking, suspension, and overall vintage design are often the more meaningful limits in normal highway use.

The practical question is less whether the tire has a dramatic top-speed number and more whether the whole car is prepared for sustained road driving. A healthy vintage tire on a neglected chassis is not a safe combination. Before a longer highway run, confirm age, inflation, visible condition, and wheel integrity, then match your cruising pace to the capabilities of the car as a whole. A well-sorted Lloyd should be driven with mechanical sympathy, not modern-traffic assumptions.

Inflation pressure on a 1961 Lloyd should begin with the vehicle manufacturer's recommendation for the car and then be checked against the tire maker's rated pressure information for the exact size and product. Among these sizes, 145R13 appears with 825 pounds at 44 psi, 520-13 appears with 770 pounds at 32 psi and 1,100 pounds at 60 psi on different products, and 560-13 appears with 850 pounds at 30 psi. Those figures are tire ratings, not a universal instruction to run every Lloyd at those pressures.

That distinction is important because pressure is part of the relationship between the car, the wheel, and the tire's intended operating range. A narrow bias-ply and a metric radial do not automatically want the same inflation strategy, and one tire's sidewall rating should never be transferred to another size. Use the car's handbook as your starting point, then confirm the tire's own limits and application guidance before settling on final cold pressures.

Before taking a 1961 Lloyd on a longer drive, inspect all four road tires and the spare for sidewall cracking, weather checking, cuts, punctures, bulges, uneven wear, and proper cold inflation. Look closely at valve stems, and if the tire setup is tube-type, treat the valves and tube-related sealing points as part of the pre-trip inspection. Also make sure the wheels are sound and the tires are seated properly.

Tire inspection should sit inside a broader vintage-car check that includes brakes, steering, fluid levels, lighting, and basic tool and spare readiness. On a compact 1961 Lloyd, a small tire problem can quickly become a big interruption if you are far from home and carrying minimal trunk space. A careful pre-drive routine is the best way to avoid turning an enjoyable tour into a recovery exercise, especially on older roads or at sustained cruising speeds.
