Graham 29 Series Tires

Graham 29 Series uses two listed tire sizes for 1928: 31X6.00 and 600-19. The 31X6.00 size is an antique diameter-by-section code, while 600-19 is a numeric bias-ply size that fits a 19-inch rim. The available product coverage shown here is for 600-19, with a 19-inch rim diameter and bias-ply construction.

That split means the right choice depends on the actual wheel and tire setup on the individual Graham 29 Series, not the year alone. Start by reading the size on the existing tire if it is trustworthy, then verify the wheel diameter directly before matching a replacement. On a restoration-grade car, it is also wise to compare the setup against period photos, service information, or marque expertise.

On a Graham 29 Series, 31X6.00 is an antique diameter-by-section size. The first number, 31, refers to the tire's outside diameter in inches, and the second number, 6.00, refers to the nominal section width. It does not directly tell you the wheel diameter, which is why modern buyers often misread this type of code.

That matters because a Graham 29 Series owner cannot assume the wheel size from the tire code alone when dealing with 31X6.00. The safest approach is to measure or confirm the rim before selecting a replacement, especially on a car that may have been altered during earlier service life. Antique-style bias-ply applications of this kind also call for an inner tube as part of the complete fitment.

A 1928 Graham 29 Series has 2 tire sizes listed because two different size conventions appear within the same model year: 31X6.00 and 600-19. One is an antique outside-diameter style code, and the other is a numeric bias-ply size associated with a 19-inch rim. That difference points to variation in wheel and tire configuration rather than a simple one-size-fits-all answer.

When a single model year carries more than one listed size, the practical step is to identify the specific car's wheels before choosing a tire. Check the wheel diameter, inspect any surviving tire markings, and look for restoration records that may show whether the car stayed with its earlier-style setup or uses the 19-inch numeric size. That prevents ordering a tire by year alone and ending up with the wrong rim fit.

Graham 29 Series uses a confirmed 19-inch rim with the 600-19 size. The 31X6.00 size does not reveal rim diameter in the code itself because the leading number is overall tire diameter, not wheel size. That is the central fitment issue on this model year, since both sizes are listed for 1928.

The best way to sort that out is to inspect the actual wheels on the Graham 29 Series before selecting a tire. If the car carries a 19-inch wheel, 600-19 is the straightforward numeric size match among the listed options. If the car is fitted for the antique-style 31X6.00 application, confirm the wheel carefully and treat the size code as an overall-diameter reference rather than a rim-diameter reference.

The correct tire size for a 1928 Graham 29 Series is confirmed by the wheel and the car's existing configuration, since both 31X6.00 and 600-19 are listed for that year. The 600-19 size clearly corresponds to a 19-inch rim, while 31X6.00 uses an older style of sizing that does not state rim diameter in the code. A year-only lookup is not enough to settle the choice.

Begin with the physical car: check the wheel diameter, examine any old tire markings, and compare what you find with restoration paperwork or period reference material. If the car has already been restored, do not assume the current setup is original without verifying it. That extra step is especially important on late-1920s cars, where wheel and tire conventions were changing quickly.

The listed Graham 29 Series product coverage includes a wide whitewall sidewall style in 600-19. No additional sidewall styles are shown within the available product coverage here. That means the visible option in the current range is a period-style whitewall presentation rather than a larger selection of blackwall and whitewall alternatives.

Sidewall appearance matters on a Graham 29 Series because it strongly influences how finished the car looks at a glance. If appearance is a judging or restoration concern, compare the chosen sidewall to period photography and marque references for your particular body style and trim level. If your priority is simply matching an existing restored look, use the wheel size first and sidewall style second.

The available Graham 29 Series product coverage shown here includes 1 brand: Lester. The listed product is a Lester 600-19 bias-ply tire in the Lester Classic Bias Ply series. No other brand appears in the current product coverage for this model page.

For a buyer, that means the decision is less about comparing several brands and more about confirming that the car actually uses the supported size. Once the wheel diameter and size code are verified, the next consideration becomes whether the sidewall look and bias-ply construction suit the restoration or driving plan for the car. On a collector vehicle of this age, fitment accuracy comes before brand comparison.

The current Graham 29 Series product coverage shows one tire series: Lester Classic Bias Ply. That series name indicates a period-style bias-ply construction rather than a radial design or a separate alternate construction family. Within the available listing, there is not a broader spread of series types such as cord, balloon, or modern radial options.

That keeps the choice straightforward if your Graham 29 Series uses the 600-19 size and you want a traditional collector-car tire character. Bias-ply construction is consistent with the period feel many owners want on a late-1920s car, but the first step still remains wheel verification because the model year also carries an antique-style size listing. Construction style only helps after the size and rim are settled.

A Graham 29 Series should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, electric motors, heaters, and petroleum contamination. Tire pressures should be checked before long storage so the car is not left sitting on underinflated casings. On a pre-war collector car, that basic care matters even more because the tires often see very low annual mileage and long stationary periods.

If the Graham 29 Series will sit for months at a time, move it occasionally or support it in a way that reduces long-term flat spotting and sidewall strain. Keep the tires clean with mild soap and water rather than dressings that can mask cracking. Storage habits have a direct effect on how well an older-style collector tire retains its shape and serviceability.

Tires on a Graham 29 Series should be inspected before each drive and more thoroughly at regular intervals during the season. Look for tread separation, sidewall cracking, cuts, weather checking, irregular wear, valve stem aging, and any movement between tire and rim. On a late-1920s car using bias-ply or antique-style fitment, even small signs of deterioration deserve attention.

A practical routine is to make a quick visual check part of every outing and schedule a more careful hands-on inspection at least several times a year. If the car has been parked for a long period, inspect again before returning it to use. Collector vehicles often age their tires through time and environment more than through mileage, so appearance and condition matter as much as tread depth.

Tires on a Graham 29 Series should be replaced when age, cracking, hardening, bulges, casing distortion, or other structural concerns appear, even if the tread still looks usable. Low-mileage collector tires can age out long before they wear out. On a pre-war car, specialist inspection is a wise standard because the combination of age, tube-type construction, and infrequent use can hide developing issues.

Do not judge serviceability by appearance alone, especially if the car has sat for years or its tire history is unclear. Any tire that shows significant sidewall deterioration or has an uncertain age should be treated conservatively and evaluated before road use. Replacement timing on collector cars is governed more by condition and age than by miles traveled.

Graham 29 Series is associated here with two listed sizes for 1928: 31X6.00 and 600-19. The available replacement product coverage shown is a Lester Classic Bias Ply tire in 600-19, but the presence of both sizes means original fitment should be matched to the specific car rather than assumed across every Graham 29 Series. On a car of this age, wheel and tire details can vary within the same model year.

For restoration work, the right approach is to compare the car's wheels and surviving evidence against marque literature, period images, and club knowledge. That helps determine whether the car belongs with the antique-style size or the 19-inch numeric size. Originality questions on late-1920s vehicles are often settled by configuration details rather than by model name alone.

Correct tire fitment can absolutely affect both the appearance and the judged accuracy of a Graham 29 Series. Size, sidewall treatment, tire profile, and construction style all change how authentically a late-1920s car presents. Even when the car is mechanically sound, an obviously incorrect tire format or wheel-diameter mismatch can stand out immediately to experienced judges and collectors.

That is why restorers usually treat tire choice as part of the overall specification, not as a cosmetic afterthought. For a Graham 29 Series, confirming whether the car should wear the antique-style size or the 19-inch numeric size is the foundation of that process. Marque clubs, period photography, and established restoration references remain the best standards when value and authenticity matter.

The currently listed Graham 29 Series product coverage shows a wide whitewall sidewall style in 600-19. Whitewall presentation can be visually appropriate to the late-1920s era, but the correct look for a Graham 29 Series restoration still depends on the specific car's trim level, intended judging standard, and historical evidence. Sidewall style should be chosen alongside the correct size, not separately from it.

A restorer should first settle whether the car belongs with 31X6.00 or 600-19, then decide whether the available wide whitewall appearance matches the restoration goal. If the car is being judged, compare the sidewall look to period reference material and marque practice rather than relying on taste alone. The right sidewall can sharpen authenticity, but the wrong size will undermine it.

A properly selected and properly installed collector tire can be suitable for limited public-road use on a Graham 29 Series, provided the tire matches the wheel, the overall condition is sound, and the rest of the car is mechanically fit. Tire safety on a 1928 automobile depends on more than tread alone. Wheel condition, tube and flap condition where applicable, brake performance, steering play, and overall chassis health all matter.

Road use in a Graham 29 Series should be approached conservatively, with speeds and distances matched to the design age of the car and the condition of its components. Before any regular driving, have the wheels, tires, and running gear checked by someone familiar with pre-war vehicles. A correct tire helps, but it cannot compensate for age-related issues elsewhere in the car.

Before driving a Graham 29 Series, check tire pressure, visible sidewall condition, tread condition, valve stems, wheel fasteners, and any signs of tire movement on the rim. Also inspect for cracking, bulges, or uneven stance that could suggest inflation or structural problems. On a pre-war car, those checks should be paired with a look at brakes, steering response, suspension, and fluid leaks.

The goal is to catch small issues before they become a roadside failure. If the Graham 29 Series has recently come out of storage, give it a slower and more thorough once-over than you would a modern car, and include the spare in that inspection routine. Collector driving is safest when every outing starts with a walk-around instead of an assumption.

A Graham 29 Series should be driven at moderate, conservative speeds that respect both the age of the automobile and the character of period-style tires. Even with a fresh bias-ply tire, a late-1920s car does not behave like a modern sedan in braking, cornering, or emergency response. Tire choice supports safe operation, but it does not change the basic road manners of a pre-war vehicle.

In practical terms, smooth inputs and sensible pace matter more than trying to match modern traffic flow at all times. Use speeds that keep the car comfortable, stable, and easy to stop within the limits of its chassis and braking system. If the route demands sustained high-speed traffic or abrupt lane changes, the safer decision may be to choose a different vehicle for that trip.
