1948 Frazer Tire Fitment Guide

1948 Frazer vehicles covered here use one tire size: 710-15. That size applies to the Frazer 485 & 486 model group and mounts on a 15-inch wheel. Available products for 710-15 are built in bias-ply construction, with listed rim width compatibility of 5.00 to 5.50 inches.

That makes the first step fairly simple for a 1948 Frazer owner: confirm that the car is a 485 or 486 and that it still carries the proper 15-inch wheels. After that, the decision usually comes down to sidewall appearance, especially blackwall versus wide whitewall, rather than choosing between multiple fitment sizes.

A 710-15 marking on a 1948 Frazer tire is a traditional numeric bias-ply size. The 7.10 portion identifies the tire's nominal section width class, while the 15 indicates that the tire fits a 15-inch wheel. Unlike later metric radial sizing, it does not include a modern aspect ratio written directly into the code.

That matters because a 710-15 should be understood as an era-correct bias-ply fitment, not as a modern radial size with the same wheel diameter. If you are comparing products for a 1948 Frazer, focus on construction, sidewall style, and the wheel's actual width rather than trying to translate the code into modern metric terms too literally.

Yes. The 1948 Frazer 485 & 486 model group uses the same 710-15 tire size. There is no split here between different Frazer models in this year and make grouping, so the fitment size remains consistent across the covered range.

That shared sizing simplifies the search process for a 1948 Frazer owner because the major differences are visual and restoration-oriented rather than dimensional. Once the model is confirmed, attention can shift to whether the car is being finished as a blackwall sedan, a wide-whitewall show car, or a driver that still needs the proper period look.

1948 Frazer tires in 710-15 are available in both blackwall and wide whitewall styles. BFGoodrich offers blackwall and wide whitewall versions, while Firestone is also available in blackwall form within this size. All of these choices stay within the correct bias-ply construction for the car.

Sidewall style changes the personality of a 1948 Frazer more than many owners expect. Blackwalls tend to suit a restrained postwar look, while wide whitewalls create the brighter, more upscale presentation many collectors associate with late-1940s American sedans. The right choice depends on how original you want the finished car to appear and which visual treatment matches the restoration.

BFGoodrich and Firestone both make 710-15 tires for 1948 Frazer vehicles. In this fitment, each brand stays within bias-ply construction and the proper 15-inch wheel diameter, giving owners a choice between established American names closely associated with period-style collector tires.

Brand choice on a 1948 Frazer often comes down to the exact sidewall presentation you want and which tire series best matches the character of the car. Some restorers prefer to keep the visual identity of the tire as close as possible to a late-1940s American showroom impression, while others prioritize a particular sidewall treatment within the same era-correct size.

For the 1948 Frazer, BFGoodrich and Firestone both offer 710-15 bias-ply tires with the same listed load capacity of 1550 pounds at 32 psi and the same 15-inch rim diameter with a 5.00 to 5.50-inch rim width range. The clearest differences are sidewall presentation and product weight, with BFGoodrich available in blackwall and wide whitewall versions and Firestone shown here in blackwall form.

That means a 1948 Frazer owner is usually comparing appearance first, then brand preference within the same basic fitment envelope. If the goal is a particular whitewall width, BFGoodrich offers more than one visual treatment in this size. If the goal is a blackwall tire with a traditional American-brand identity, either brand keeps you in the correct size and construction family.

The 710-15 tires used on 1948 Frazer models fit 15-inch wheels with a listed rim width range of 5.00 to 5.50 inches. That width range applies across the available products in this size, so the wheel itself should fall within that window before a tire is selected.

A wheel can have the right diameter and still be a poor match if its width is outside the intended range. Before fitting new tires to a 1948 Frazer, measure the actual wheel width and confirm that the wheels on the car are the correct originals or faithful replacements. That extra check helps avoid appearance issues and prevents unnecessary mounting complications.

The available 710-15 listings for 1948 Frazer do not carry a tube-type or tubeless marking in the size designation, so the tire itself should be matched to the wheel and the specific product's sidewall marking before deciding on tube use. With late-1940s vehicles, the wheel design and condition are just as important as the tire when making that decision.

A 1948 Frazer owner should inspect the original wheel carefully for bead-seat condition, corrosion, previous repairs, and any wheel features that affect air retention. If the car still uses original wheels, many restorers also consult a Kaiser-Frazer specialist or wheel shop before mounting tires, especially when the car will be driven more than occasionally.

A 1948 Frazer should be stored in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age rubber. Bias-ply tires also benefit from correct inflation during storage and from occasional movement, since long static parking can encourage temporary flat-spotting more readily than a radial construction would.

If the car will sit for months at a time, keep the tires clean, avoid petroleum-based dressings, and consider repositioning the vehicle periodically or supporting it appropriately to reduce stress on one contact patch. Collectors who preserve wide whitewalls should also keep them away from staining sources and clean them gently so the sidewall finish stays crisp.

Tires on a 1948 Frazer usually age out before they wear out, especially on collector cars that see limited mileage. A good rule is to evaluate them closely once they reach the five-to-seven-year range and to treat around ten years as a point where replacement deserves serious consideration, regardless of remaining tread depth. The DOT date code on the tire helps establish age.

That schedule matters because an older bias-ply tire can look usable from a distance while the rubber has already hardened or begun to crack. A 1948 Frazer that appears only at shows or goes on short drives still puts demands on its tires, so age, storage history, and sidewall condition are often more important than miles traveled.

Tires on a 1948 Frazer should be inspected before every drive and again before any extended outing. Look for sidewall cracking, tread separation, bulges, punctures, uneven wear, and pressure loss. The valve stems should also be checked closely, since a vintage car can spend enough time parked for rubber components to age without obvious warning.

A short local drive may not reveal a developing problem that becomes serious at highway speed or under a full day of heat cycling. Building a quick pre-drive routine around tire pressure, visible condition, and spare-tire readiness is one of the simplest ways to keep a 1948 Frazer dependable and reduce the risk of a roadside interruption.

A 1948 Frazer 485 & 486 would have been fitted in the bias-ply era, and the correct fitment used here is 710-15. That places the car squarely in the late-1940s American practice of bias-ply construction on 15-inch wheels. The exact sidewall treatment could vary by market presentation and owner preference, but the size and construction family are consistent with the period.

For a restoration aiming at factory-style authenticity, start with 710-15 bias-ply tires and then refine the choice around blackwall or wide whitewall appearance. If you are chasing show-level accuracy, it is wise to compare your car against period photos, sales literature, and Kaiser-Frazer club guidance before settling on the final sidewall look.

Correct tire fitment matters on a 1948 Frazer because judges and knowledgeable enthusiasts notice size, construction, and sidewall style very quickly. A 710-15 bias-ply tire keeps the car aligned with its era, while an incorrect size or a visibly modern construction can change the stance and undercut the period presentation even if the car is otherwise carefully restored.

Show standards vary, so the level of scrutiny depends on whether the car is entering a general local event or a marque-focused judging field. Owners pursuing a serious concours result should verify the expected sidewall treatment for their specific restoration theme and use marque-club resources to settle any final appearance questions before the car is judged.

For a 1948 Frazer, blackwall and wide whitewall 710-15 tires share the same basic fitment, wheel diameter, and bias-ply construction. The difference is visual character. Blackwalls present a cleaner, more restrained appearance, while wide whitewalls create a brighter, more formal postwar American luxury look that many collectors associate with late-1940s sedans.

Choosing between them depends on the personality you want the finished 1948 Frazer to project. A conservative restoration or a car meant to echo a simpler delivery appearance may lean toward blackwalls, while a fully trimmed sedan with strong period style often looks most at home on wide whitewalls. Either way, keeping the correct 710-15 size is the foundation for an authentic stance.

1948 Frazer tires can be suitable for highway driving when they are the correct size, in sound condition, and inflated properly for the application. The available 710-15 tires here are bias-ply products, so they deliver the period-style driving character expected of a late-1940s American car rather than the feel of a modern radial. On a car of this age, overall mechanical condition often matters just as much as the tire itself.

A highway-ready 1948 Frazer should have more than fresh-looking tires. Wheel condition, alignment, suspension wear, steering play, brake performance, and the age of the spare all deserve attention before sustained road use. If the car has been off the road for a long period, a careful recommissioning is the smart step before trusting it on longer or faster drives.

The available 710-15 tires for 1948 Frazer list a maximum load capacity of 1550 pounds at 32 psi. That figure identifies the tire's rated load-and-pressure point, but it is not automatically the running pressure every car should use in every condition. Factory vehicle recommendations and actual vehicle loading still matter.

Use the original owner's manual or marque reference for the vehicle's intended operating pressure, then compare that with the tire maker's guidance for the reproduction tire you are using. A 1948 Frazer owner should avoid borrowing a pressure figure from a different size or a modern vehicle, since ride quality, tread wear, and steering feel can all change noticeably when inflation is off.

Before taking a 1948 Frazer on a longer drive, inspect each tire for cracking, cuts, bulges, embedded debris, uneven wear, and stable inflation pressure. Check the valve stems, inspect the spare, and make sure the wheels themselves are clean and free of obvious damage around the bead area. On a collector car, the tires should be part of a broader pre-drive inspection rather than the only item checked.

A 1948 Frazer also deserves a quick review of brakes, steering, wheel bearings, cooling system condition, and basic fluid levels before covering real distance. Even when the tires are correct and freshly mounted, the age of the car means reliability comes from the whole system working together. A little preparation goes a long way toward turning a cautious test run into a confident day trip.
