The 1957 Lloyd LT belongs to the postwar wave of compact European economy cars that prioritized light weight, efficiency, and small-displacement practicality over excess. For owners today, that means tire selection has an outsized effect on both appearance and road manners, because these cars ride on narrow 15-inch tires. The 1957 Lloyd LT uses either a 135R15 radial or a 500-15 bias-ply, depending on the setup you want to maintain. That opens the door to a traditional bias-ply look, a simple blackwall radial presentation, or a more restoration-minded whitewall choice. The real decision is matching the tire to your wheel, your driving habits, and the character you want the car to retain.
Which Tire Size Is Right for The 1957 Lloyd LT
The 1957 Lloyd LT uses two primary tire sizes, both on 15-inch rims: 135R15 in radial construction and 500-15 in bias-ply construction. Both the LT 500 and LT 600 use these same sizes, so the key decision is not sub-model identification but whether you want a radial or bias-ply setup, along with the sidewall style and tire series that best suit the car.
135R15 is a Euro-metric radial size in which 135 refers to the nominal section width in millimeters, R indicates radial construction, and 15 is the wheel diameter in inches. On a 1957 Lloyd LT, this size gives the car a narrow postwar European tire profile while using modern radial construction. Available choices include Michelin and Firestone blackwall tires in series such as Michelin X M+S 89, Michelin ZX, and Firestone F560 Radial. It is a useful size for owners who want a period-appropriate overall look with radial construction, provided the wheel width and vehicle clearance are checked carefully.
500-15 is a numeric bias-ply size, with 5.00 representing the nominal section width in inches and 15 identifying the rim diameter. This is the traditional bias-ply format associated with many small mid-century cars and gives the 1957 Lloyd LT a distinctly vintage stance and appearance. Choices in this size include BFGoodrich blackwall and wide whitewall tires in the Silvertown Classic Bias Ply series, along with a Firestone Dirt Track blackwall option. This size makes the most sense for owners who want to preserve a more traditional tire presentation and are confirming that their wheels match the required bias-ply fitment.
Tire fitment is straightforward across the covered 1957 Lloyd LT sub-models, because both the LT 500 and LT 600 use the same 135R15 radial and 500-15 bias-ply sizes. That means the main choice is construction and appearance rather than a difference between sub-model tire dimensions.

1957 Lloyd LT 500
The 1957 Lloyd LT 500 can be fitted with either a 135R15 radial or a 500-15 bias-ply on a 15-inch wheel. Tire selection comes down to whether the car is being kept in a more traditional bias-ply style or set up with a narrow blackwall radial for regular road use.
The 1957 Lloyd LT 600 uses the same 135R15 radial and 500-15 bias-ply sizes as the LT 500. That keeps the buying decision focused on construction, sidewall appearance, and wheel compatibility rather than any sub-model-specific tire-size difference.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Owners researching tires for a 1957 Lloyd LT usually need to sort out size, 15-inch rim fitment, radial versus bias-ply construction, and the difference between blackwall and whitewall choices. These FAQs focus on the practical decisions that matter before the car goes back on the road.
Tire Size & Fitment
What tire size fits a 1957 Lloyd LT?
The 1957 Lloyd LT uses two primary tire sizes: 135R15 in radial construction and 500-15 in bias-ply construction. Both sizes are built for 15-inch rims, and both the LT 500 and LT 600 are associated with these same tire sizes.
That means the main fitment decision is choosing the construction and presentation you want rather than sorting through different sub-model sizes. A radial 135R15 keeps the narrow European look with a more modern tire format, while a 500-15 bias-ply maintains a more traditional vintage setup. Wheel width and overall vehicle clearance should still be checked before making the final choice.
What size rim does a 1957 Lloyd LT use?
The 1957 Lloyd LT uses a 15-inch rim with both of its primary tire sizes, 135R15 and 500-15. That shared rim diameter makes it easier to compare the car's radial and bias-ply tire choices without changing the basic wheel diameter.
Rim diameter is only one part of the fitment picture, so it is still important to confirm the actual wheel width on the car before selecting a tire. Some 135R15 radial products are built around a 3.50 to 4.50 inch rim-width range, while the available 500-15 bias-ply choices use narrower or different wheel-width requirements depending on the product.
Do all 1957 Lloyd LT sub-models use the same tire size?
Yes. The covered 1957 Lloyd LT sub-models, including the LT 500 and LT 600, use the same two tire-size options: 135R15 radial and 500-15 bias-ply. There is no separate tire-size split between those sub-models on this page.
That consistency simplifies the search, but it does not remove the need to inspect the car's current wheels and tire setup. Many collector cars have been changed over the years, and a Lloyd that has been stored, restored, or modified may not still be wearing the wheel width or tire construction you expect. Matching the replacement tire to the actual wheel is still the right first step.
Choosing the Right Tire
What should I consider when choosing a 1957 Lloyd LT tire?
Start with the correct size and construction for the setup you want to run. A 1957 Lloyd LT can use a 135R15 radial or a 500-15 bias-ply, both on 15-inch rims, so the first real choice is whether you want a more modern radial format or a more traditional bias-ply presentation.
After that, compare the details that affect how the tire suits the car: rim-width requirements, sidewall style, tire series, and basic load specifications where they are shown. A narrow radial blackwall gives a different visual result than a bias-ply wide whitewall, even when both are suitable sizes. The right choice depends on appearance goals, driving habits, and the wheels actually on the car.
What sidewall styles are available for 1957 Lloyd LT tires?
The available sidewall styles for the 1957 Lloyd LT are primarily blackwall and wide whitewall. The 135R15 radial options are blackwall tires, while the 500-15 bias-ply selection includes both blackwall and a 2.00 inch wide whitewall option.
That sidewall choice has a major effect on the car's finished look. Blackwalls tend to preserve a simpler, utilitarian small-car appearance, while a wide whitewall shifts the visual character toward a more decorative restoration style. Sidewall styling should be chosen after the correct size and construction are settled, since appearance does not override wheel compatibility or overall fitment.
What brands offer tires for the 1957 Lloyd LT?
Tires for the 1957 Lloyd LT are available from Michelin, Firestone, and BFGoodrich. Michelin and Firestone cover the 135R15 radial size, while BFGoodrich and Firestone appear in the 500-15 bias-ply size through different tire series and sidewall treatments.
Brand comparison is most useful when it is tied to the size and style you actually need. In this application, the more important distinctions are whether you are choosing radial or bias-ply construction, whether you want blackwall or wide whitewall appearance, and whether the tire's rim-width specification matches the wheel on the car. Those factors narrow the field faster than brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1957 Lloyd LT?
For a period-style 1957 Lloyd LT, the 500-15 bias-ply is the most traditional-looking starting point. Its vintage numeric sizing and bias-ply construction suit the character of a small late-1950s European car, and it is available in both blackwall and wide whitewall form depending on the presentation you want.
A 135R15 radial can still be appropriate for an owner who wants a narrow classic profile with radial construction, but it changes the character of the tire choice. If exact restoration authenticity matters, use marque-specific references, period photos, or other historical sources to confirm the sidewall style and overall look you want before choosing between blackwall and whitewall options.
How does tire construction affect the appearance of a restored 1957 Lloyd LT?
Tire construction changes the visual impression of a restored 1957 Lloyd LT more than many owners expect. A 500-15 bias-ply gives the car a more traditional mid-century look through its vintage sizing format and classic sidewall proportions, while a 135R15 radial presents a narrower European-style blackwall radial appearance.
The difference is not only technical; it changes how the whole car sits visually and how authentic the finished restoration feels to the eye. Sidewall treatment matters too, since a blackwall and a wide whitewall create very different results even within the same size. Construction should be chosen as part of the overall restoration theme, not as an afterthought.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1957 Lloyd LT?
Yes. A 1957 Lloyd LT may be associated with 135R15 radial and 500-15 bias-ply sizes, but modifications can change how either size works on the car. Wheel replacements, altered wheel width, suspension changes, body repairs, or changes in ride height can all affect clearance and how the tire sits.
Even when the tire size itself is correct, the actual fit should be checked against the car as it is currently configured. A Lloyd with aftermarket wheels or non-stock suspension may need closer attention to wheel width, steering clearance, and fender space than a car on its original-style setup. Looking at the car before ordering avoids choosing by size code alone.
What should I inspect before driving a 1957 Lloyd LT on new tires?
Before driving a 1957 Lloyd LT on new tires, inspect the wheels for correct diameter and width, look for damage or heavy corrosion, and make sure the tires are mounted in the intended size and construction. Check inflation pressure, valve condition, and whether the tire clears suspension, steering, and body surfaces through full movement.
A collector car also deserves a quick chassis review before road use, especially if it has been sitting. Worn steering parts, weak shocks, old bushings, or dragging brakes can make any new tire feel wrong. A careful first drive should include listening for rubbing, watching for pull or vibration, and rechecking pressure after the initial miles.
How should 1957 Lloyd LT tires be maintained?
Tires on a 1957 Lloyd LT should be maintained with regular pressure checks, visual inspections, and occasional close examination for cracking, bulges, cuts, uneven wear, or slow air loss. Because this is a collector-era car, tire age and storage conditions matter almost as much as tread depth.
Cars that spend long periods parked should be kept away from prolonged sunlight, excess heat, moisture, and ozone sources such as electric motors or battery chargers. Moving the car periodically can help avoid flat-spotting, and any change in vibration or handling should prompt another inspection. Maintenance is especially important on narrow vintage-size tires, where small problems can show up quickly on the road.
