Morgan Series Tires

Morgan Series fitments in this range are 500-16 for 1957 and 1958, then 135R15 and 500-15 for 1959. The 500-16 size uses a 16-inch rim, while both 1959 sizes use 15-inch rims. That means the car moved from a 16-inch wheel fitment to 15-inch wheel fitments at the end of the span.

The practical step is to identify the year first, then confirm the wheel diameter actually fitted to the car. A 1959 Morgan Series needs an extra layer of checking because two different size formats appear in the same year: a metric radial and a numeric bias-ply. If the car has been restored, re-wheeled, or set up for a particular driving style, the tire code on the old tire and the wheel diameter should both be checked before moving forward.

On a Morgan Series, 500-16 is a traditional numeric bias-ply size. The 500 indicates a nominal 5.00-inch section width, and the 16 indicates a 16-inch rim diameter. In the available Morgan Series products for this size, the tire is a bias-ply design built for a 16-inch wheel.

That matters because 500-16 belongs to the earlier 1957-1958 fitment, not the 1959 15-inch setup. Numeric bias-ply sizes also carry different ride and steering character than later radial sizes, so the code is doing more than naming width and wheel diameter. If your Morgan Series still wears its earlier wheel package, this size keeps you in the correct dimensional family and construction style for that period.

A 1959 Morgan Series has two listed sizes because that year includes both 135R15 and 500-15 fitments. Both use 15-inch rims, but they represent different sizing systems and different constructions: 135R15 is a radial metric size, while 500-15 is a numeric bias-ply size. The split is a construction and specification split rather than a wheel-diameter split.

That means year alone is not enough to choose a tire for a 1959 Morgan Series. You need to determine whether the car is set up for a bias-ply or a radial tire and confirm the wheel width as well. Cars restored for period appearance often stay with the numeric bias-ply size, while some drivers prefer the radial option for road use. The safest path is to inspect the current wheels and compare them with the size already fitted.

Morgan Series models in this range use two rim diameters. The 1957 and 1958 fitment, 500-16, uses a 16-inch rim. The 1959 fitments, 135R15 and 500-15, both use 15-inch rims, so the wheel diameter changed in the final year covered here.

That wheel-size change is the first thing to verify on the actual car because a 15-inch tire cannot substitute for a 16-inch rim, or the other way around. Morgan cars are often maintained over long periods and can pick up wheel changes during restoration or use. Measure the wheel or read the existing tire sidewall before narrowing the search to a bias-ply or radial option.

Morgan Series fitments here include both bias-ply and radial choices, but they are not spread evenly across every year. The 1957-1958 fitment is a numeric bias-ply 500-16, while 1959 includes both the bias-ply 500-15 and the radial 135R15. That means the right answer depends first on the year and wheel package, then on whether originality or later-style road behavior is the priority.

Choose bias-ply on a Morgan Series when you want a more period-correct appearance and traditional driving character. Choose radial only where the car is set up for the radial size listed for that application, in this case 135R15 on a 1959 15-inch fitment. Either way, keep the decision consistent with the wheel diameter and the intended use of the car rather than treating construction as a cosmetic choice.

A Morgan Series fitted with radial tires can feel different from one on bias-ply tires because the construction type changes the way the tire flexes, tracks, and responds to steering inputs. In the sizes listed here, the radial option is 135R15 and the bias-ply options are 500-16 and 500-15. That means any comparison is not only radial versus bias-ply, but also tied to the correct year and wheel size.

For the driver, the key point is to expect a change in road feel rather than assuming every tire in the list will behave the same way. A lightweight sports car like a Morgan Series is sensitive to narrow-tire construction differences, so the choice affects the character of the car as much as the specification sheet. If preserving period manners matters, bias-ply remains the more historically aligned direction.

A Morgan Series should not be treated casually when mixing bias-ply and radial constructions, especially in a short-wheelbase, lightweight sports-car layout. The listed fitments already separate the constructions by size, with 500-16 and 500-15 as bias-ply choices and 135R15 as the radial choice. Those tires are meant to be used as complete, matched sets within the correct wheel diameter.

The practical implication is simple: if your Morgan Series is on the 1959 15-inch wheel setup, decide whether the car will run the radial or the bias-ply fitment and keep the set uniform. Mixing constructions can alter steering response and balance in ways that are far more noticeable on a light collector car than on a modern sedan. Consistency across all four corners is the sensible approach.

A 1959 Morgan Series can use either 135R15 or 500-15, and both are 15-inch fitments. The critical distinction is construction and size system: 135R15 is a metric radial, while 500-15 is a numeric bias-ply. Available products also show different rim-width ranges within those choices, so wheel setup matters as well as the year.

Start by confirming the wheel diameter on the car, then read the existing tire size if the current setup is known to be correct. After that, decide whether the goal is period-style bias-ply presentation or the listed radial alternative for 1959. On a Morgan Series, that sequence avoids choosing a tire by year alone and missing an important difference in construction or wheel compatibility.

Morgan Series tires in this range are available in blackwall and wide whitewall styles. The 135R15 radial options are blackwall, the 500-16 bias-ply product is blackwall, and the 500-15 bias-ply range includes both blackwall and a 2.00 inch whitewall version. That gives a traditional appearance choice within the 1959 500-15 fitment.

For most sporting Morgan Series applications, blackwall is the more restrained and era-appropriate visual direction, especially for the narrower radial and utility-focused bias-ply options. A wide whitewall can suit a particular restoration taste, but it changes the presentation of a compact British sports car more noticeably than it would on a larger American car. Match the sidewall look to the character you want the finished car to project.

Morgan Series tires in these listed sizes come from Firestone, Michelin, and BFGoodrich. Firestone appears in both 500-16 and 500-15 offerings, Michelin provides the 135R15 radial choices, and BFGoodrich appears in the 500-15 bias-ply range. That gives the Morgan Series a mix of period-style bias-ply and later radial brand options depending on year and configuration.

Brand should come after size, wheel diameter, and construction in the decision process. Once the correct Morgan Series fitment is confirmed, the brand choice can help refine the car toward a more sporting, more traditional, or more road-oriented presentation. It is better to start with the proper size family and then compare brands within that fitment than to choose a brand first and force the car into the wrong specification.

Morgan Series products here include Firestone Dirt Track, Michelin X M+S 89, Michelin ZX, Firestone F560 Radial, and BFGoodrich Silvertown Classic Bias Ply series. The key difference is construction and purpose: the Michelin and Firestone radial series belong to the 135R15 radial fitment, the Silvertown Classic Bias Ply series belongs to the 500-15 bias-ply fitment, and the Dirt Track series appears in bias-ply 500-16 and 500-15 forms. Those are distinctly different approaches, not minor cosmetic variations.

For a Morgan Series owner, the series choice should match the car's intended use and visual direction after the correct size has been established. A classic bias-ply series supports a more traditional restored appearance, while the radial series suit the listed 1959 radial setup. The Dirt Track series is more specialized in character, so it deserves extra attention to how the car will actually be used rather than being treated as a general replacement.

A Morgan Series should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, and prolonged moisture. Tire pressures should be checked before the car is parked for any length of time so the casing is not left underinflated. On a lightweight collector car, long static periods can still create flat spotting, especially with bias-ply tires.

If the Morgan Series will sit for months, move it periodically or support it in a way that reduces continuous load on one section of the tire. Clean tires with mild soap and water only, and avoid dressings that can dry or discolor the rubber. Good storage habits matter as much as mileage on collector tires because age and environment are often harder on them than actual road use.

Tires on a Morgan Series should be inspected before every meaningful drive and more thoroughly several times each season. Look for sidewall cracking, tread separation, impact damage, irregular wear, and changes in inflation pressure. On narrow vintage sizes, those issues can develop without many miles simply because collector cars spend long periods parked.

The inspection should include the tire bead area, valve stems, and the wheel itself, since an old wheel can create problems that look like tire trouble. A Morgan Series with bias-ply tires also benefits from periodic checks of tube-related issues such as slow pressure loss or chafing symptoms. Frequent inspection is inexpensive insurance on a car whose handling depends heavily on a small contact patch.

A Morgan Series tire should be replaced when age, cracking, hardening, vibration, or casing damage appears, even if the tread still looks deep. Collector tires often age out before they wear out, particularly on lightly used sports cars. Any tire showing structural concerns, repeated air loss, or visible deterioration has moved beyond a cosmetic issue.

That standard matters because low-mileage collector cars can fool owners into thinking a tire is still serviceable simply because it looks barely used. The safer approach is to judge a Morgan Series tire by condition and age as much as by tread. If the car has been off the road for a long period, have the tires examined before resuming use rather than assuming old rubber is trustworthy because it still has pattern depth.

Morgan Series fitments in this range include 500-16 for 1957-1958 and both 135R15 and 500-15 for 1959. The available tire series span bias-ply and radial products, including Silvertown Classic Bias Ply, Michelin radial lines, and Firestone Dirt Track offerings. That means the correct original-style direction depends on the exact year and the specific configuration of the car rather than on the model name alone.

For restoration work, use the listed year-and-size relationship as the starting point and then compare it with factory literature, period photographs, and marque-club guidance for the individual car. That is especially important in 1959, where two construction styles appear under one model-year umbrella. Originality in a Morgan Series restoration often comes down to getting the wheel diameter, sidewall appearance, and construction type aligned at the same time.

Correct tire fitment can affect both presentation and credibility on a Morgan Series because the car's proportions are so dependent on narrow tires and the proper wheel diameter. Judges and informed buyers tend to notice whether the tire construction, sidewall treatment, and stance match the year and style of the restoration. A mismatch between 16-inch and 15-inch-era fitments is particularly easy to spot.

For a car being restored for show, the tire should support the year-correct character of the Morgan Series rather than merely filling the wheel opening. Even for a driver-quality car, proper fitment helps protect long-term value by showing that the restoration was done with care. Marque clubs and period reference materials remain the best tie-breakers when the owner is choosing between two plausible-looking options.

Morgan Series products here include blackwall and wide whitewall sidewall styles. Blackwall appears across the radial 135R15 options, the 500-16 bias-ply offering, and one 500-15 bias-ply option, while a 2.00 inch wide whitewall is also available in 500-15. That means restoration appearance can vary depending on which 1959 bias-ply direction is being pursued.

For most Morgan Series restorations, blackwall is the more restrained and sporting look, and it aligns naturally with the model's lightweight British character. A wide whitewall creates a more stylized period impression and may suit a specific owner's vision, but it is a stronger visual statement. The best choice is the one that matches the car's exact year, wheel setup, and restoration objective rather than personal preference alone.

Morgan Series tires can be appropriate for public-road use when the tire size, construction, wheel diameter, and overall condition all match the car correctly. In this fitment group, that means respecting the difference between the 1957-1958 16-inch bias-ply setup and the 1959 15-inch bias-ply or radial alternatives. A properly matched tire in sound condition is the baseline requirement, not an optional refinement.

The practical issue is that a Morgan Series is light, responsive, and very sensitive to tire condition, so old or mismatched rubber changes more than comfort. Before driving on public roads, inspect inflation, sidewalls, tread, and wheel condition and make sure all four tires belong to the same fitment plan. Collector-car road use is safest when tire age and condition are taken as seriously as the nominal size.

Before driving a Morgan Series, check tire pressure, visible sidewall condition, tread condition, valve stems, and the tightness and condition of the wheels. Also confirm that the car is wearing a matched set in the correct size family rather than a mix of 16-inch and 15-inch-era thinking. If the car is on bias-ply tires, extra attention to pressure consistency is worthwhile because small changes can be felt quickly.

A short pre-drive walkaround is especially important on a collector sports car that may sit for long periods between outings. Look for fresh cracks, flat spotting, or any sign that the tire has lost shape since the last drive. That habit takes only a few minutes and helps catch age-related problems early, which is far better than discovering them once the Morgan Series is already moving.

A Morgan Series on period-style tires should be driven at moderate, sensible speeds that respect both the age of the car and the construction of the tire fitted to it. Bias-ply and narrow vintage-size tires ask for more restraint than many modern drivers expect, even when the tread looks healthy. The safe mindset is to treat the tire as part of an older system rather than assuming modern high-speed behavior.

In practice, that means building speed gradually, avoiding abrupt steering inputs, and keeping road use within the comfort zone of the car's vintage chassis and tire construction. A Morgan Series fitted with the listed radial option may feel more settled than one on bias-ply tires, but condition still matters more than theory. If there is any doubt about age, balance, or structural condition, keep speeds conservative until the setup is evaluated.
