1926 Lexington Tire Fitment Guide

1926 Lexington vehicles in this guide use two sizes: 30X5.77 and 30x5. Both sizes apply to the 1926 Lexington 50, and both are bias-ply designs from the antique diameter-by-section era rather than later numeric, alphanumeric, or metric formats. Since only one model is covered here, the fitment question is less about model family and more about confirming which of those two sizes belongs on your particular car.

That distinction matters because antique sizes are closely tied to the wheel and the car’s established restoration pattern. A Lexington owner should compare the existing tire size, wheel markings, restoration paperwork, and any period literature tied to the specific car before choosing between 30X5.77 and 30x5. If the car has changed hands or been restored more than once, consulting a Lexington or broader pre-war marque specialist is a smart next step.

On a 1926 Lexington tire, 30X5.77 is an antique diameter-by-section size. The first number, 30, refers to the tire’s overall diameter, while 5.77 refers to the nominal section width. That is very different from later sizing systems that place the rim diameter at the end of the code, which is why this format can look unfamiliar to modern buyers.

Understanding that code helps prevent a common restoration mistake: assuming the size behaves like a later passenger-car number. On a pre-war Lexington, the code reflects an earlier approach to tire specification and should be matched carefully to the wheel and the car’s established fitment. If your car is being judged for authenticity, keeping the antique-style size convention in mind is just as important as choosing the correct construction type.

Within this year-and-make range, the only model covered is the 1926 Lexington 50, and it appears with two tire sizes rather than one. That means there is no broad multi-model size split to sort through, but there is still a real fitment choice between 30X5.77 and 30x5. Both belong to the same pre-war, bias-ply tire world, yet they are not interchangeable by assumption.

For a buyer, the practical takeaway is simple: year and make alone are not enough if your Lexington 50 has a long restoration history. Verify the size already associated with the car, especially if the wheels, hubs, or previous tires were changed decades ago. That step is more useful here than trying to compare trim levels, because the deciding factor is the exact antique size tied to your specific car.

A 1926 Lexington owner should choose between 30X5.77 and 30x5 by confirming which size belongs on the car, not by treating one as a general upgrade over the other. Both are bias-ply, period-appropriate styles for a mid-1920s Lexington, so the decision is about correct fitment and authenticity rather than choosing between bias-ply and radial behavior.

That usually means checking the wheel, any surviving original references, and the restoration history before selecting a product. If your goal is show-oriented originality, staying with the exact size associated with the car is especially important. If the car is primarily driven on tours, fitment accuracy still comes first, because the construction type remains the same and the size code is the main point of difference.

The available size information for 1926 Lexington identifies the two correct antique sizes but does not establish a broad modern brand comparison at the year-make level. What matters most for this car is finding the correct antique-size bias-ply offering that matches the Lexington 50’s established fitment and restoration goals.

Pre-war buyers generally benefit more from starting with the exact size and construction than from starting with brand preference alone. Once the correct size is confirmed, the next step is comparing the tires built in that size for sidewall appearance, period character, and compatibility with the wheel setup already on the car. That approach keeps the restoration grounded in fitment first and branding second.

1926 Lexington tires belong to an era when sidewall appearance is a major part of the car’s finished look, especially on a substantial pre-war automobile like the Lexington 50. Antique-size bias-ply tires are often chosen as much for period visual character as for dimensions, so the sidewall style can affect how authentic the car appears even when the size itself is correct.

A restored Lexington should use a sidewall treatment that suits mid-1920s American luxury-car presentation and the way the car is being judged or displayed. Owners building for national-level authenticity often verify sidewall appearance with period photography, marque literature, or club guidance before making a final selection. That extra step helps avoid ending up with a tire that fits physically but looks out of place on the car.

A 1926 Lexington uses antique-era bias-ply tire sizes, and cars of this period commonly rely on tube-type wheel and tire arrangements rather than later tubeless practice. The exact tube requirement should always be confirmed against the specific tire and wheel combination being used, because pre-war wheels and restoration histories can vary from car to car.

When recommissioning a Lexington 50, tube condition deserves the same attention as the outer tire itself. Aged tubes, valve stems, flaps where applicable, and rim-condition issues can all affect reliability even when the tread looks fresh. Owners who are replacing long-installed tires should inspect the whole assembly together rather than assuming a serviceable-looking wheel setup is ready for immediate road use.

1926 Lexington tires in sizes 30X5.77 and 30x5 should be matched to the correct antique wheel specification for the car rather than estimated from modern passenger-car habits. These sizes come from an earlier sizing system in which the tire code alone does not read like a modern width-and-rim formula, so wheel confirmation is part of the fitment process.

A Lexington owner should verify the actual wheel dimensions and construction before mounting replacement tires, especially if the car has had wheels swapped during restoration or touring use. Pre-war cars can accumulate mixed components over many decades, and that can create confusion if the tire size on the car no longer matches the original setup. Checking the wheel first reduces the risk of choosing the right-looking tire for the wrong rim.

A 1926 Lexington should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, furnaces, and other ozone-producing equipment that can age rubber prematurely. Bias-ply tires on low-use collector cars are especially prone to developing temporary flat spotting during long stationary periods, and old pre-war suspension designs do little to hide that once the car is back on the road.

Keeping the tires properly inflated, rolling the car occasionally, or using stands as part of a longer-term storage plan can help reduce stress on the casing. Clean floors, moderate temperatures, and protection from moisture are just as important on a Lexington as they are on the body and upholstery. A car stored carefully is far more likely to return to service without sidewall distress or vibration issues.

Tires on a 1926 Lexington should be judged more by age and condition than by mileage, because collector cars often travel very little each year. A sensible rule is to begin evaluating them closely once they are in the five-to-seven-year range and to treat around ten years as a point where replacement deserves serious consideration, even if tread depth still looks acceptable.

The DOT date code and the tire’s actual storage history matter more than odometer readings on a pre-war car. Sidewall cracking, hardening, persistent air loss, and changes in ride behavior can all signal that age is becoming the limiting factor. A Lexington that appears lightly used can still be riding on rubber that is no longer appropriate for regular touring or sustained road speeds.

Tires on a 1926 Lexington should be inspected before every drive and again before any longer outing or touring event. A quick check should include visible cracking, bulges, cuts, unusual tread wear, and pressure retention, with extra attention paid to valve stems and tube-related hardware if the car uses a tube-type setup as many pre-war cars do.

That routine matters because collector vehicles often sit for extended periods, and problems can develop between drives rather than during daily use. Early detection is especially valuable on a heavy, substantial automobile like a Lexington 50, where tire issues can affect ride quality, steering feel, and confidence at speed. Making tire inspection part of the pre-drive ritual is one of the easiest ways to keep the car road-ready.

A 1926 Lexington 50 would have been built in the bias-ply era, so bias-ply construction is the historically appropriate starting point for original-type fitment. The year-make fitment range here includes 30X5.77 and 30x5, both of which are antique-style sizes consistent with pre-war tire practice rather than later numeric or radial replacements.

For exact car-by-car originality, owners should compare surviving literature, wheel markings, and knowledgeable Lexington or pre-war marque sources before finalizing the size. Market variations, running production changes, and decades of restoration work can all influence what is on a given car today. Keeping the original-style construction and the correct antique size together is the strongest foundation for an authentic restoration.

Correct tire fitment matters a great deal when showing a 1926 Lexington because judges and knowledgeable enthusiasts notice whether the tire size, construction type, and overall period appearance suit the car. A pre-war luxury automobile wearing the wrong size or an obviously later-style tire can look visually off even before detailed judging begins.

For serious show presentation, the tire should support the car’s era and stance rather than merely fill the wheel opening. Sidewall appearance and construction type can influence authenticity almost as much as the size marking itself on a 1920s car. Owners planning concours participation should always confirm event-specific expectations with the sponsoring club or judging body before committing to a final setup.

Antique tire sizing is important on a 1926 Lexington because the car belongs to a period before modern passenger-car tire conventions took over. Sizes such as 30X5.77 and 30x5 describe the tire in an older diameter-by-section language, and that older language influences both how the car sits and how accurately it reflects 1920s fitment practice.

Treating those sizes as if they were later numeric or metric codes can lead to visual and mechanical mismatches. On a Lexington 50, the tire is a major styling element as well as a functional one, so preserving the correct antique proportion helps the restoration look settled and believable. That is one reason experienced pre-war restorers verify the original size format before making any substitution.

1926 Lexington tires can be used for road driving when they are in proper condition, correctly fitted, and appropriate to the car, but they should be understood within the limits of antique bias-ply design and pre-war vehicle engineering. A Lexington 50 is not a modern highway car, and its brakes, steering, suspension behavior, and general road manners are just as important to safety as the tire itself.

For today’s roads, the bigger question is whether the entire car is prepared for sustained driving, not simply whether the tires are new. Tire age, inflation, wheel condition, and the car’s mechanical readiness all deserve attention before longer runs. Owners who keep speeds sensible and treat the car as the 1920s automobile it is will usually make better decisions than those who judge it by modern standards.

Inflation pressure for 1926 Lexington tires should follow the original vehicle guidance for the car and the operating limits of the specific reproduction tire being used. Antique bias-ply tires should never be inflated by guesswork or by copying a pressure from an unrelated modern tire, because the correct setting depends on the exact size, the vehicle, and the tire maker’s specifications.

The best approach is to start with the Lexington’s period recommendation when available and then confirm that it aligns with the tire’s own rated pressure range. Pressure affects steering effort, ride harshness, casing shape, and tread wear on a pre-war car more noticeably than many owners expect. Checking all five tires, including the spare, is wise before touring because an emergency replacement is only useful if it is equally roadworthy.

Before taking a 1926 Lexington on a longer drive, inspect each tire for cracking, cuts, bulges, uneven wear, and proper inflation, and check the valve stems and tube-related components if the car uses them. The spare should be examined with the same care as the four road tires, since a spare that has aged in place for years may no longer be trustworthy.

A longer outing in a pre-war car should also include a broader mechanical check of brakes, steering play, fluids, cooling, and wheel hardware. The tire inspection is one part of a complete readiness routine, not a separate task. On an automobile like the Lexington 50, small problems that seem manageable around town can become much more serious once the car is asked to cover distance at sustained road speed.
