1957 Rover Tire Fitment Guide

1957 Rover vehicles use five sizes across the range: 750-16 for the Rover 109, 175R15 and 600-15 for the Rover 60, Rover 75, and Rover 75, 90, 105R & 105S saloon group, and 175R16 plus 600-16 for the Rover 88. The 15-inch saloon tires mount on 15-inch rims, while the utility-model tires mount on 16-inch rims. Published rim-width ranges appear for 750-16 at 5.00-6.00 inches, for 600-15 at 4.00-4.50 inches or 4.50-5.00 inches depending on the tire, and for 600-16 at 4.00-4.50 inches.

That means year and make alone are not enough to select a tire for a 1957 Rover. The first checkpoint is whether you have a saloon, an 88, or a 109, because the wheel diameter changes with the model group. Once the model is confirmed, the next step is deciding whether your car or utility Rover calls for the available bias-ply size, the available radial size, or a specific sidewall treatment that suits your restoration goals.

On a 1957 Rover, 600-15 is a numeric bias-ply size. The 600 refers to nominal section width in the older inch-based sizing system, and the 15 indicates a 15-inch rim diameter. That size appears on the Rover 60, Rover 75, and Rover 75, 90, 105R & 105S saloon group, not on the Rover 88 or Rover 109. Available versions include both blackwall and wide whitewall styles from BFGoodrich.

Numeric sizes like 600-15 are familiar territory for restorers because they match the way many mid-century cars were originally sized before metric radial markings became common. If your 1957 Rover is one of the saloon models and you want a traditional visual profile, this is the size to evaluate first. The final check is wheel width, since one 600-15 tire is approved for 4.00-4.50-inch rims and another is approved for 4.50-5.00-inch rims.

No, 1957 Rover models do not share one universal tire size. The Rover 109 uses 750-16, the Rover 88 uses either 175R16 or 600-16, and the Rover 60, Rover 75, and Rover 75, 90, 105R & 105S saloon group use either 175R15 or 600-15. That split follows the practical difference between Rover's saloon cars and its utility-oriented Land Rover-derived models, with 15-inch rims on the saloons and 16-inch rims on the utility models.

For buyers, that makes model identification essential before comparing brands, sidewalls, or construction types. A saloon owner may be choosing between a 15-inch radial and a 15-inch bias-ply tire, while an 88 owner is choosing between two different 16-inch codes and a 109 owner stays in a separate larger numeric size entirely. Checking the wheel on the vehicle and the sidewall of any existing tire is a worthwhile confirmation step before making a final selection.

For a 1957 Rover 60, Rover 75, or Rover 75, 90, 105R & 105S saloon, the choice between 175R15 and 600-15 is mainly a choice between radial and bias-ply construction on a 15-inch wheel. The 175R15 is the radial option for those saloon models, while 600-15 is the numeric bias-ply size. The radial route usually appeals to owners who want a more modern tire construction, while the bias-ply route is the traditional fitment style associated with the period.

A careful buyer should start by deciding how the car will be used and presented. If originality of look and era-correct construction matters most, 600-15 is the natural place to focus. If the goal is to run one of the saloons on the radial size listed for that model group, 175R15 is the relevant path. Either way, keep the choice within the sizes associated with your exact saloon model rather than assuming all 1957 Rover cars used one standard tire.

1957 Rover tires are offered in both blackwall and wide whitewall form in several of the bias-ply sizes shown here. The 750-16 size for the Rover 109 appears in blackwall and wide whitewall versions, 600-15 for the saloon group appears in blackwall and wide whitewall, and 600-16 for the Rover 88 also appears in both styles. That gives buyers room to match the visual character of the tire to the specific Rover they are restoring or driving.

For many British vehicles of the period, blackwalls are the safer starting point when the goal is a restrained factory-type appearance, while whitewalls create a more stylized presentation that can suit certain restoration tastes and market-specific looks. Sidewall style is not just decoration on a collector vehicle; it changes the visual weight of the car and can affect judging impressions. If show authenticity matters, compare your chosen sidewall treatment with period photos, club guidance, and the way your Rover is being restored.

Several brands cover the available 1957 Rover sizes shown here. The 750-16 size is offered by Firestone, Lester, and BFGoodrich; 600-15 appears from BFGoodrich; and 600-16 appears from BFGoodrich, Coker Classic, Avon, and Firestone. Those offerings are concentrated in the bias-ply sizes, with a mix of blackwall and wide whitewall presentations depending on the size and brand.

Brand choice usually comes after you have narrowed the search to the correct size and construction for your Rover model. Once that is settled, the brand decision becomes more about sidewall appearance, period flavor, and any published details such as rim-width range or listed load figure. Comparing products within the correct size is more useful than comparing brands across different Rover models, because the saloons, the 88, and the 109 do not all share the same fitment.

Published rim-width ranges vary by size on 1957 Rover applications. The 750-16 size used on the Rover 109 is approved for 5.00-6.00-inch rims in the listed products. The 600-15 size used on the Rover saloon group appears with approved ranges of 4.00-4.50 inches on one product and 4.50-5.00 inches on another, while the 600-16 size used on the Rover 88 is listed for 4.00-4.50-inch rims.

That spread matters because correct rim width affects section shape, sidewall stance, and how closely the tire matches its intended profile. Two tires with the same nominal size can still have different approved wheel ranges from one product line to another. Before choosing a 1957 Rover tire, confirm both the diameter and the actual wheel width on the vehicle so the tire selected matches the wheel you intend to use rather than just the size code on paper.

The listed 1957 Rover bias-ply products shown here do not carry TT or TL markings in the size field, so tube requirement should be confirmed at the product level and against the wheel itself before installation. That is especially relevant on older Rover applications, where wheel design, rim condition, and the tire selected all influence whether tube-type service is appropriate. The radial sizes listed for the saloon and Rover 88 model groups should likewise be matched to the specific tire's sidewall marking and the wheel being used.

Older collector vehicles often sit in the gray area where tire construction and wheel design meet, and that is where assumptions cause trouble. A 1957 Rover owner should verify whether the wheel is intended for tube-type service, inspect the rim for corrosion or damage, and match the valve-stem arrangement to the tire setup. If you are moving between bias-ply and radial options on the same model group, that is also a good time to confirm the complete wheel-and-tire package rather than treating all products in the size as identical.

On the 1957 Rover saloon group, both listed sizes for a given model family share a 15-inch rim diameter, and on the Rover 88 both listed sizes share a 16-inch rim diameter. That means the original wheel diameter can align with either the bias-ply or radial path within that model group. Rim width still has to be checked against the individual tire, because the published approved widths for the bias-ply products are specific and should not be assumed across every tire option.

In practice, the original wheel can be part of the solution, but diameter alone is not the whole fitment story. Measure the wheel, verify its condition, and compare its width to the tire you are considering before deciding that both listed sizes are automatically compatible. That step is especially worthwhile on a 1957 Rover that has seen decades of ownership changes, replacement wheels, or mixed restoration work, where what is on the vehicle now may not match what the model originally carried.

A stored 1957 Rover should be kept out of direct sunlight, away from electric motors or ozone-producing equipment, and on a clean, dry surface. Tire pressures should be maintained during storage, and the vehicle should be rolled periodically or supported in a way that reduces prolonged static loading. Because bias-ply tires are part of the mix on 1957 Rover applications, they are more prone to temporary flat-spotting after long periods of sitting than a radial construction usually is.

Good storage habits protect both appearance and service life, especially on a collector Rover that may see long stretches between drives. If the vehicle is stored for an extended season, cover the tires from light exposure and check them periodically for pressure loss and sidewall changes. Bringing the tires back into use gently after storage, rather than immediately heading onto a long highway run, gives you a chance to feel for flat spots, vibration, or other age-related issues before they become a bigger problem.

Tires on a 1957 Rover should be judged more by age, condition, and storage history than by mileage alone. Collector-vehicle tires often age out before they wear out, so a careful owner should begin evaluating them closely around the five- to seven-year mark and treat roughly ten years as the point where replacement deserves serious consideration even if tread remains. The DOT date code, along with visible sidewall and tread condition, is the key reference for that decision.

Low annual mileage can create a false sense of security on an older Rover. A tire that looks acceptable at a glance may still have hardened rubber, internal age issues, or cracking that makes it a poor candidate for continued road use. Age-based replacement is especially important on vehicles that spend time parked, because inactivity often does more long-term harm than steady use. When in doubt, judge the tire as a time-sensitive component rather than a mileage-based one.

Tires on a 1957 Rover should be inspected before every drive and again before any extended outing. Look for sidewall cracking, tread separation, cuts, bulges, embedded debris, and any loss of air pressure since the last time the vehicle was used. If your Rover is running a setup that uses tubes, the valve stems and their seating deserve close attention as well, since slow air loss can begin there before it becomes obvious in the tread or sidewall.

Frequent inspection matters more on collector vehicles than on daily drivers because long periods of sitting can hide deterioration until the car is finally put back on the road. A five-minute walkaround before departure can reveal problems that would otherwise show up as vibration, pull, or a roadside failure later. For a 1957 Rover that sees occasional tours or club drives, add a pressure check and a look at the spare so the backup tire is as trustworthy as the four on the car.

For a 1957 Rover 75, bias-ply construction is the period-correct starting point to think about, because bias-ply tires were still standard equipment across much of the industry in that era even as radial adoption was beginning to grow. Within the sizes shown for the Rover 75, 600-15 is the bias-ply fitment and 175R15 is the radial alternative associated with the model group. The exact market, trim, and owner-delivery specification can still influence what a particular car carried when new.

That means originality-minded owners usually begin with the bias-ply size, then verify details against factory literature, period photos, and Rover marque specialists. If your goal is a judged restoration, sidewall style and construction type matter almost as much as the basic size code. A car presented with a radial where judges expect a period bias-ply can look immediately out of character, even if the wheel diameter is correct, so it pays to confirm the standards that apply to your event.

Correct tire fitment matters a great deal when showing a 1957 Rover, especially in classes that reward factory-correct presentation. Judges and knowledgeable enthusiasts often notice whether the size, construction type, and sidewall treatment suit the era and the model. A saloon on a modern-looking radial or a utility Rover wearing an overly stylized sidewall can change the visual authenticity of the vehicle even if the tire physically fits the wheel.

The standard to follow depends on how the Rover will be judged. Some events are strict about construction and sidewall appearance, while others allow more flexibility for road-use upgrades. Before finalizing the tire choice, compare your car to period references and consult Rover clubs or marque registries that know the expectations for the specific model. That extra step helps prevent small tire-related details from undermining an otherwise accurate restoration.

Within the 750-16 size for the 1957 Rover 109, BFGoodrich and Firestone differ in sidewall presentation, weight, and listed load figures among the products shown. Firestone appears in a blackwall version and a 4.50-inch whitewall version, each with a listed maximum load of 1660 pounds at 40 psi and weights of 29 to 31 pounds. BFGoodrich appears with a 4.125-inch whitewall, a listed maximum load of 1850 pounds at 48 psi, and a weight of 30 pounds. Both are approved on 5.00-6.00-inch rims in the listed products.

For a 1957 Rover 109 owner, the practical difference comes down to the appearance you want and how closely the tire's published details line up with your restoration plan. Whitewall width changes the look immediately, and the listed load-and-pressure figures are not identical between the two brands. Since both fit the same nominal size category, the smarter comparison is within the 750-16 family itself rather than against tires used on the saloon models or the Rover 88.

1957 Rover tires can be suitable for highway driving when the tire is in good condition, correctly matched to the wheel, and used within its construction and rating limits. The clearest published speed marking in the listed products appears on the Avon 600H16 93H for the Rover 88, where H corresponds to a 130 mph ceiling. Other listed bias-ply products do not show a speed letter in the size marking here, so they should be treated according to the manufacturer's own specifications and the operating realities of an older Rover.

On a vehicle of this age, tire capability is only one part of the highway equation. Brakes, steering, suspension, wheel condition, and overall mechanical health often become the more meaningful limits at normal road speeds. A well-prepared 1957 Rover should be entirely capable of sensible touring, but the right mindset is steady, conservative use rather than pushing the car or tire to a theoretical maximum. Matching speed to the vehicle's age and condition is every bit as important as choosing the correct size.

Inflation pressure on a 1957 Rover should not be guessed from size alone. The listed tires show different load-and-pressure pairings by size and product: 750-16 appears at 1660 pounds at 40 psi and also 1850 pounds at 48 psi depending on the tire, 600-15 appears at 1150 pounds at 32 psi, and 600-16 appears at 1400 pounds at 32 psi, with one Avon 600H16 listing 1,433 pounds. Those are tire capability figures, not blanket instructions to inflate every Rover tire to the same pressure.

The best practice is to start with the vehicle manufacturer's recommended operating pressure for the specific model, then confirm that the tire you are using is being run within its own rated limits. That matters because a 1957 Rover saloon, Rover 88, and Rover 109 do not carry the same tires or the same load requirements. If you change construction type or move to a different product line, review the sidewall information and the maker's guidance before setting your final pressures.

Before a longer drive in a 1957 Rover, inspect all five tires if a spare is carried, not just the four on the ground. Check for cracking, bulges, cuts, uneven wear, foreign objects, and any sign that a tire has been losing pressure while the vehicle sat. Confirm pressures when the tires are cold, and if the Rover is using a tube-type arrangement, include the valve stems and stem hardware in the inspection because they are common sources of trouble on older setups.

A longer outing also deserves a broader mechanical walkaround because tire safety on a vintage Rover depends on the whole vehicle, not just the rubber. Wheel fasteners, steering response, brake feel, and wheel-bearing condition all deserve attention before setting out. Taking ten extra minutes in the garage can prevent a short tire issue from becoming a roadside event, and it also helps you catch whether a tire problem is really the first visible symptom of a larger chassis or wheel-related fault.
