1958 Rover Tire Fitment Guide

1958 Rover vehicles use five sizes across the full model range: 750-16 for the Rover 109, 175R15 and 600-15 for the Rover 60, Rover 75, and Rover 75, 90, 105R & 105S saloons, and 175R16 plus 600-16 for the Rover 88. The saloon sizes mount on 15-inch wheels, while the Land Rover sizes mount on 16-inch wheels. Listed rim-width guidance appears on some products, including 5.00-6.00 inches for several 750-16 tires, 4.00-4.50 or 4.50-5.00 inches for 600-15, and 4.00-4.50 inches for several 600-16 products.

That means year and make alone are not enough to choose correctly. A Rover saloon owner first needs to confirm the exact model group and then decide between the two available constructions in the proper 15-inch size family, while a Land Rover owner needs to confirm whether the vehicle is an 88 or 109 because those models do not use the same 16-inch fitment.

On a 1958 Rover, 600-15 is a numeric bias-ply size. The 6.00 designation refers to the tire's nominal section width in inches, and the 15 identifies the wheel diameter in inches. On Rover applications for 1958, that size belongs to the 60, 75, and 75, 90, 105R & 105S saloon models rather than the Land Rover 88 or 109.

This is the size to look at if you are trying to keep a 1958 Rover saloon in a period-appropriate bias-ply fitment. It is also a reminder that old numeric sizing does not describe a modern metric tread package, so a buyer comparing 600-15 with 175R15 should think in terms of era-correct construction versus radial road behavior, not just a simple one-to-one modern equivalent.

On a 1958 Rover, 175R15 is a Euro-metric radial size. The 175 figure gives the nominal section width in millimeters, the R indicates radial construction, and the 15 is the wheel diameter in inches. For 1958 Rover applications, this size is used on the 60, 75, and 75, 90, 105R & 105S saloon models.

That code matters because it points you toward a different construction family than 600-15, even though both belong to the same saloon group. Owners who drive their Rover saloon regularly often begin by considering the radial option, while owners focused on a more traditional restoration presentation usually compare against the bias-ply size before making a final choice.

If your 1958 Rover is a 60, 75, or 75, 90, 105R & 105S saloon, both 175R15 and 600-15 are part of the proper fitment family for those models, but they represent different constructions. The 175R15 is a radial size, while the 600-15 is a bias-ply size. The choice is less about forcing an unrelated fitment and more about deciding which construction better suits how you want the car to look and feel on the road.

A buyer leaning toward period presentation will usually start with 600-15, especially if maintaining the visual character of a 1950s Rover saloon is the priority. A buyer planning more routine road miles often begins with 175R15 because radial construction changes the driving character. The right answer depends on your model, your goals for the car, and whether restoration authenticity or regular-use behavior sits higher on your list.

1958 Rover tires are available in both blackwall and wide whitewall styles, but the exact sidewall choice depends on the size. The 750-16 products for the Rover 109 include blackwall and wide whitewall versions, the 600-15 saloon bias-ply options include both blackwall and wide whitewall, and the 600-16 offerings for the Rover 88 also span blackwall and wide whitewall styles. The listed 175R15 and 175R16 radial fitments are part of the size inventory, but sidewall style choices are not represented here in the same way as the bias-ply products.

For a 1958 Rover buyer, sidewall choice is mostly an appearance and authenticity decision once the correct size is identified. Conservative blackwalls generally suit the working Land Rover image and many understated British saloons, while whitewalls can shift the look toward a more accessorized period presentation. If the car will be judged, check the expectations for your exact model and market before choosing a sidewall treatment.

Current 1958 Rover fitments include products from Firestone, Lester, BFGoodrich, Coker Classic, and Avon, depending on size. The 750-16 Rover 109 size includes Firestone, Lester, and BFGoodrich choices. The 600-15 saloon bias-ply size is represented by BFGoodrich, while the 600-16 Rover 88 bias-ply size includes BFGoodrich, Coker Classic, Avon, and Firestone.

Brand choice comes after the more important step of confirming your model and size family. Once the correct fitment is narrowed down, the brand decision usually becomes a question of sidewall appearance, series preference, and any specific load or speed details attached to the product. Comparing brands within the correct size is useful; comparing brands across the wrong Rover model is not.

Rim-width guidance varies by size on 1958 Rover tires. Several 750-16 products for the Rover 109 call for 5.00 to 6.00-inch rims. The 600-15 saloon tires appear with two different fitment windows depending on product, one at 4.00 to 4.50 inches and another at 4.50 to 5.00 inches. Several 600-16 Rover 88 products specify 4.00 to 4.50-inch rims.

That variation is a good reason to verify the actual wheel before making a final selection, especially on older vehicles that may have had wheel changes over the decades. Staying within the listed rim-width range helps preserve proper bead seating and sidewall shape. If your Rover still wears original wheels, measure them or confirm their size through a trusted marque source rather than relying on assumption.

The listed 1958 Rover bias-ply products do not carry a universal tube marker in every case, so tube fitment should be confirmed against the exact tire and wheel combination you plan to use. The radial and bias-ply sizes span different eras of construction practice, and the wheel itself matters just as much as the tire. On collector vehicles, original-style wheels often drive the final tube decision.

The safest approach is to treat tube fitment as a product-by-product and wheel-by-wheel confirmation step rather than a blanket rule for every 1958 Rover. If your wheels are older riveted or non-safety-rim designs, that becomes especially important. Check the tire's sidewall marking and match it to the wheel type before mounting, rather than assuming all tires in the same listed size use the same setup.

Original 1958 Rover wheels cannot be treated as universal across the full make because the lineup uses both 15-inch and 16-inch tire families, and the Land Rover and saloon models do not share one common fitment. The saloons use 175R15 or 600-15, the Rover 88 uses 175R16 or 600-16, and the Rover 109 uses 750-16. Diameter alone rules out swapping across much of the range.

Within an individual model family, the original wheel may accommodate more than one tire choice, but the correct way to confirm that is by checking both diameter and the listed rim-width range for the specific product. That matters most on saloons where bias-ply and radial alternatives exist in the same general application. Start with the wheel you have, not the tire you hope to use.

A 1958 Rover should be stored in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that accelerate sidewall aging. Keep the tires properly inflated, and if the car will sit for long periods, move it occasionally or place it on stands in a way that relieves some load. Bias-ply tires are especially prone to taking a temporary set during storage, and they also tend to show age cracking sooner when neglected.

Those habits matter whether you have a saloon on 600-15 or 175R15 sizes or a Land Rover on 16-inch rubber. Collector cars often age their tires out long before they wear them out, so storage conditions have an outsized effect on how the sidewalls look and how smoothly the car drives after sitting. A simple storage routine can prevent flat-spot complaints and preserve the appearance of expensive reproduction tires.

Tires on a 1958 Rover should be judged more by age than mileage. A collector vehicle may only cover modest distances each year, yet the rubber still hardens and the casing still ages over time. A practical rule is to begin evaluating condition closely once tires are around five to seven years old and to consider replacement around the ten-year mark regardless of remaining tread, using the date code and the tire's visible condition as your guide.

That timeline is especially relevant for vehicles like a 1958 Rover that may be driven seasonally, shown occasionally, and parked for long stretches. A tread-rich tire is not necessarily a fresh tire. If the car's service history is hazy, confirming the age of the fitted tires is one of the smartest first checks before returning the vehicle to regular road use.

Tires on a 1958 Rover deserve a quick inspection before every drive and a more careful one before any extended outing. Look for sidewall cracking, cuts, bulges, uneven wear, embedded debris, and signs that the tire is losing pressure between uses. On older fitments where tube use may apply depending on wheel and product choice, valve stems and the spare tire deserve the same attention.

That routine is especially important on collector cars because problems often appear from age and inactivity rather than from heavy mileage. A Rover that has been parked for weeks can hide a low tire, a split stem, or a fresh crack that was not there on the last drive. Making inspections part of the start-up ritual is one of the easiest ways to avoid trouble on the road.

A 1958 Rover 75 would have been associated with period bias-ply practice when new, and within the 1958 Rover fitment family the relevant saloon bias-ply size is 600-15. The same model group is also represented with 175R15 radial fitment in today's selection, but that reflects an alternate construction path rather than changing the fact that bias-ply was the era-correct starting point for many late-1950s cars. Original-market and trim-specific details can still vary.

For a restoration, 600-15 is the logical first place to begin if your goal is visual and historical alignment with late-1950s Rover presentation. If you are preparing the car for judged events, verify the expected sidewall style and construction standard with Rover club resources or event rules. That extra step matters because judges often look beyond simple size and notice whether the overall tire character matches the period.

Correct tire fitment absolutely matters when showing a 1958 Rover, especially on events that emphasize originality. Judges and knowledgeable enthusiasts often notice whether the size, construction type, and sidewall appearance suit the model and era. A Rover saloon presented on a modern radial when the goal is strict authenticity can attract the same kind of attention as an incorrect whitewall treatment or an obviously mismatched profile.

That does not mean every restored Rover must wear the same tire, because different owners build cars for different standards and different shows enforce originality in different ways. It does mean you should decide early whether the car is being restored to a driver standard or a judged standard. Once that goal is clear, selecting among the appropriate 1958 Rover sizes becomes much more straightforward.

Within the 600-16 size for a 1958 Rover 88, the Avon Turbospeed is listed as 600H16 93H, carrying an H speed rating up to 130 mph and a listed max load of 1,433 pounds. The BFGoodrich 600-16 offering is a bias-ply tire with a listed max load of 1400 pounds at 32 psi and is available in wide whitewall form. Both stay within the same basic size family, but they differ in sidewall presentation and in the way their published specifications are expressed.

That comparison matters most for buyers who already know they need a 600-16 for a Rover 88 and are now narrowing the final product. One choice may better suit a traditional visual theme, while another may appeal because of its rating format and blackwall presentation. Comparing the exact sidewall style, published load figure, and intended use of the vehicle is more useful here than treating all 600-16 products as interchangeable.

1958 Rover tires can be suitable for highway use when the correct size and a sound, age-appropriate tire are chosen for the vehicle. The clearest published speed rating in this group appears on the Avon 600H16 93H for the Rover 88, where H indicates a ceiling of 130 mph. Other listed Rover tires here are primarily bias-ply or radial reproduction fitments without the same visible speed-rating detail, so overall condition, age, inflation, and proper matching to the car matter at least as much as the size code itself.

On a 1958 Rover, the vehicle's own mechanical realities are often the bigger limiter than the tire at ordinary U.S. highway speeds. Brakes, steering, suspension, wheel condition, and alignment all deserve attention before a long freeway run. A fresh, properly fitted tire helps, but it is only one part of making an older Rover comfortable and trustworthy on modern roads.

Inflation pressure on 1958 Rover tires should be matched to the exact size and product rather than borrowed from another Rover model. Published figures in this group include 750-16 products at 1660 pounds at 40 psi and 1850 pounds at 48 psi, 600-15 at 1150 pounds at 32 psi, and 600-16 at 1400 pounds at 32 psi, with the Avon 600H16 showing a 1,433-pound load figure. Those are tire ratings, not automatic factory running pressures for every Rover application.

The best practice is to use the original Rover owner's literature or marque guidance for the vehicle's recommended operating pressure, then confirm that choice against the tire manufacturer's limits for the exact product you are fitting. Never transfer a pressure figure from a 109 to an 88 or from a 600-15 saloon tire to a different size, because each fitment has its own load and casing characteristics.

Before a longer drive in a 1958 Rover, inspect all four tires and the spare for cracking, cuts, bulges, uneven wear, and proper inflation. Make sure the tires are the correct size for the model, look closely at valve stems, and verify that any older wheel-and-tire combination has been mounted appropriately for its design. If the Rover has been sitting, give extra attention to flat spotting and pressure loss.

That tire check should happen alongside a broader vintage-car review that includes wheel fasteners, brakes, steering, fluids, and cooling system condition. A healthy set of tires cannot overcome mechanical neglect elsewhere, especially on a late-1950s car or utility Land Rover. Treat the tire inspection as the first part of the departure routine, not the only part.
