1958 Lloyd Tire Fitment Guide

Three tire sizes apply across the 1958 Lloyd range. The Lloyd LC, LP, and LS use 4.25-15 bias-ply tires. The Lloyd LT uses either 500-15 bias-ply or 135R15 radial tires. All of those sizes mount on 15-inch rims, and published rim-width guidance appears on available LT products at 3 inches for some 500-15 tires, 4.00 to 5.00 inches for the Firestone 500-15 Dirt Track, and 3.50 to 4.50 inches for 135R15 Michelin ZX and Firestone radial products.

That means year and make alone are not enough to choose correctly. If you own an LC, LP, or LS, your path is straightforward because those models center on 4.25-15. If you own an LT, you need to decide between the traditional 500-15 bias-ply fitment and the 135R15 radial alternative, then confirm that your actual wheel width matches the specific tire you intend to run.

On a 1958 Lloyd, 4.25-15 is a numeric bias-ply tire size. The 4.25 refers to the tire's nominal section width in inches, and the 15 refers to the wheel diameter in inches. This format belongs to an older sizing system commonly found on small European cars and other mid-century vehicles that originally used bias-ply construction.

For a Lloyd LC, LP, or LS, that code is more than just a measurement shorthand; it points you toward the correct style of tire for the car's period. A modern metric radial code looks very different, so mixing the two systems without checking the model can lead you in the wrong direction. If your sidewall or old records show 4.25-15, stay focused on that model group before comparing products.

On a 1958 Lloyd, 135R15 is a Euro-metric radial tire size. The 135 is the section width in millimeters, the R identifies radial construction, and the 15 is the wheel diameter in inches. In common period usage, a size written this way without a stated aspect ratio is typically an 80-series style metric radial, which matches the available 135R15 offerings for the Lloyd LT.

That matters because 135R15 belongs only to the Lloyd LT, not to the LC, LP, or LS. It also signals a different construction philosophy from the older numeric bias-ply sizes used elsewhere in the range. If you are trying to identify what is already on your LT, the presence of the R is the quickest clue that you are looking at the radial option rather than the 500-15 bias-ply alternative.

For a 1958 Lloyd LT, the choice between 135R15 and 500-15 is mainly a choice between radial and bias-ply construction. The 135R15 options are blackwall radials from Michelin and Firestone, while the 500-15 options are bias-ply tires from BFGoodrich and Firestone in blackwall and wide whitewall forms. Both fit 15-inch rims, but they represent different approaches to how the car will look and feel.

Owners pursuing a period-style presentation usually start with 500-15 because it stays within the older numeric bias-ply format and keeps the vintage character more intact. Owners who expect more regular road use often look at 135R15 because radial construction changes the driving experience in a more modern direction. The right answer depends on how authentic you want the LT to appear and how you plan to use it once finished.

Sidewall style depends on the size you need for your 1958 Lloyd. The 135R15 radial choices for the Lloyd LT are blackwall only. The 500-15 bias-ply options for the LT include both blackwall and wide whitewall versions. The 4.25-15 fitment used by the LC, LP, and LS is part of an earlier-style size family, so sidewall appearance should be chosen with restoration intent in mind.

For most European economy cars of the late 1950s, blackwalls are the safer visual direction when the goal is market-correct appearance. A wide whitewall can create a stronger custom or stylized period look, but it changes the presentation more noticeably on a small-bodied car like a Lloyd LT. If authenticity matters for showing or judging, compare your target look against period photos and marque-club guidance before finalizing sidewall style.

Available 1958 Lloyd tire brands include Michelin, Firestone, and BFGoodrich. In 135R15 for the Lloyd LT, Michelin offers the X M+S 89 and ZX, and Firestone offers the F560 Radial. In 500-15 for the LT, BFGoodrich offers blackwall and wide whitewall bias-ply versions, while Firestone offers a Dirt Track Ribbed front tire in the same size.

Brand choice on a Lloyd often comes down to the size and style you need rather than make loyalty alone. Michelin has a strong period association with small European radial applications, while BFGoodrich and Firestone cover the bias-ply side with different visual and use-case personalities. Once you have the correct size nailed down, compare the brand options within that size instead of trying to force one brand across every Lloyd model.

Rim-width guidance is available for several 1958 Lloyd tire choices and varies by size and product. The 135R15 Michelin ZX and Firestone radial products fit 3.50 to 4.50-inch rims. Two BFGoodrich 500-15 bias-ply tires list a 3-inch rim, while the Firestone 500-15 Dirt Track Ribbed front tire lists a 4.00 to 5.00-inch rim range. All of these are 15-inch rim-diameter tires.

That spread is the reason wheel width should be checked before you settle on a specific product, especially on the LT where both radial and bias-ply choices exist. A tire may have the correct overall size code and still expect a different wheel width than the one currently on the car. Measuring the wheel or confirming it against a known spec is a worthwhile step before mounting anything new.

Inner-tube status depends on the exact 1958 Lloyd tire product and size. The 135R15 Michelin X M+S 89 and Michelin ZX are marked TL, which identifies them as tubeless products. The Firestone 135R15 listing does not carry a tube marker in the size description, and the available 500-15 listings do not show a tube designation in the size line either, so tube use should be confirmed from the specific tire and wheel combination rather than assumed across the board.

Older wheels and older tire sizes often blur the line between what the tire itself permits and what the wheel safely supports. If your Lloyd still has original-style wheels, inspect their condition carefully and verify whether the wheel is suitable for tubeless service. Matching valve stems, wheel sealing condition, and any tube recommendation from the tire maker all matter just as much as the sidewall code.

All listed 1958 Lloyd tire sizes use a 15-inch rim diameter, so they share basic diameter compatibility at the wheel. That applies to 4.25-15 on the LC, LP, and LS and to both 500-15 and 135R15 on the LT. Rim width is the next checkpoint, because available products in the LT sizes call for different wheel widths depending on the exact tire selected.

For an LT owner, that means the wheel diameter alone does not settle the question. A car that currently wears one 15-inch size may still need a wheel-width check before switching to another 15-inch option, especially when moving between an older bias-ply fitment and a metric radial. Keeping the original wheels is often possible, but verifying the wheel against the chosen tire avoids an expensive mismatch.

A 1958 Lloyd should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, and other ozone-producing equipment that can age rubber prematurely. Keep the tires clean, maintain proper inflation, and move the car periodically so one section of tread and sidewall does not stay loaded in the same position for months at a time. Bias-ply tires are especially prone to flat-spotting during long static storage.

If the car will sit for a season or longer, many collectors either roll it occasionally or place it on stands to reduce constant load on the tires. That is especially useful for Lloyds because they are often hobby cars that spend more time parked than driven. A simple storage routine protects ride quality, minimizes sidewall aging, and helps preserve the look of expensive vintage-style tires.

Tires on a 1958 Lloyd should be judged more by age and condition than by mileage. Collector-car tires commonly deserve a careful professional evaluation once they reach about five to seven years of service, and many owners treat ten years from the date code as the outer edge for continued use even if tread depth still looks good. Age-related hardening and cracking matter more on a lightly used vintage car than simple wear-out.

That is why checking the DOT date code and overall condition is just as important as choosing the right size. A Lloyd that is driven only to shows or on occasional local runs may still age its tires out long before the tread is gone. Replacing older tires on time preserves predictability and keeps a small, light car from being undermined by rubber that looks presentable but has already aged past its comfort zone.

Tires on a 1958 Lloyd should be inspected before every drive and again before any longer outing. Look for cracking at the sidewall and tread base, cuts, bulges, uneven wear, and signs that the tire has been losing pressure while parked. If your setup uses tubes, include the valve stems and any signs of slow leakage in that inspection routine.

Frequent inspections matter because collector vehicles can sit for long periods and then be asked to run at sustained road speeds with little warning. A quick walk-around catches most problems while they are still small and manageable. On a compact vintage car like a Lloyd, even modest tire issues can have an outsized effect on steering feel and stability, so routine checks should be part of every startup ritual.

A 1958 Lloyd LT would have been associated with period-correct bias-ply fitment when new, which aligns with the 500-15 size listed for the model. The 135R15 radial option reflects a later radial-style replacement path rather than the baseline mid-1950s small-car expectation. In that era, bias-ply construction still remained standard on many economy cars, especially in applications designed around narrow 15-inch wheels.

If you are restoring an LT for authenticity, start by treating 500-15 bias-ply as the historically appropriate direction and then confirm market-specific details with period literature or a Lloyd marque specialist. Original-equipment branding and exact visual details could vary by market and timing, so construction type, size family, and sidewall appearance usually matter more than chasing a brand name first. That approach keeps the restoration grounded without overreaching.

Correct tire fitment does matter when a 1958 Lloyd is judged for originality. Size, construction type, and sidewall style all affect whether the car presents as era-appropriate, and judges or knowledgeable enthusiasts will often notice if a small postwar European car sits on a modern-looking radial or an obviously non-period sidewall treatment. On an LT, for example, 500-15 bias-ply reads very differently from 135R15 radial in a show field.

That does not mean every event applies the same standard. Some shows reward preservation and authenticity closely, while others are more relaxed about discreet usability upgrades. If points and historical correctness matter, compare your tire choice against period photos, factory literature, and the judging standards of the club or event you plan to attend. Tire construction is one of the most visible mechanical choices on a compact classic.

For a 1958 Lloyd LT in 135R15, the Michelin ZX and Firestone F560 Radial share radial construction, blackwall styling, and a 15-inch rim diameter, and both list a 3.50 to 4.50-inch rim-width range. The Michelin ZX is marked 135SR15 72S TL, giving it an S speed rating to 112 mph and tubeless construction. The Firestone F560 Radial lists a maximum load of 780 pounds at 44 psi and weighs 13.2 pounds, while the Michelin ZX weighs 12 pounds.

Those differences make the comparison more about specification details than about basic fitment. The Michelin gives you an explicit S speed rating and tubeless marking, while the Firestone provides a clearly stated load-and-pressure figure and a slightly heavier listed weight. For an LT owner comparing two radial choices, the sensible next step is to match those details to the wheel width on the car and the kind of driving the finished Lloyd will actually see.

A 1958 Lloyd can be highway-capable when the tires are fresh, correctly sized, properly inflated, and suited to the way the car is used. Among the radial LT options, Michelin offers a Q-rated 135R15 with a 100 mph ceiling and an S-rated 135SR15 with a 112 mph ceiling. Bias-ply choices are better understood as period-style tires whose road behavior reflects older construction, and a Lloyd's own braking, suspension, and power limits usually matter more than the tire's published speed ceiling in normal driving.

Real-world safety comes from treating the whole car as a 1950s machine, not from reading one number on the sidewall. A radial LT tire may offer a more modern feel on the road, but the car still deserves sensible speeds and extra following distance. Whatever model you own, the safest approach is to match the tire to the car, inspect it carefully, and drive within the limits of both the tire and the vehicle itself.

Inflation pressure for a 1958 Lloyd should begin with the factory recommendation for the car and then be checked against the tire's own load-and-pressure markings where they are published. In 500-15, two BFGoodrich bias-ply products list 700 pounds at 32 psi, while the Firestone Dirt Track Ribbed lists 675 pounds at 32 psi. In 135R15, the Firestone radial lists 780 pounds at 44 psi. Those figures describe tire capacity at stated pressure and should not be transferred casually from one size to another.

Use the owner's manual or period service literature for the starting pressure appropriate to your Lloyd model, because vehicle weight distribution and intended ride characteristics matter. Then confirm that the tire you select is being used within its own rated range. This is especially important on the LT, where radial and bias-ply options differ not just in construction but also in the pressure and load information published for individual products.

Before a longer drive in a 1958 Lloyd, inspect each tire for sidewall cracking, cuts, punctures, bulges, uneven wear, and proper inflation. Check the valve stems, and if your setup uses tubes, pay special attention to any signs of slow leakage or stem deterioration. Do not forget the spare, because an aged spare is common on collector cars and may be unusable when finally needed.

Tires are only one part of the checklist, but they are the easiest place to catch trouble before it becomes a roadside problem. On a small vintage car, a minor tire issue can quickly feel major once the car is loaded for a trip or exposed to sustained speeds. Pair your tire inspection with a broader check of brakes, wheel fasteners, fluids, and lights so the Lloyd is ready as a complete system rather than just on fresh rubber.
