Gardner 85 Series Tires

Gardner 85 Series was part of the late 1920s American luxury car field, built during a period when premium makes balanced smooth road manners, substantial chassis engineering, and increasingly modern styling. A 1928 Gardner 85 Series sits in that transitional pre-war era where tire selection is not always straightforward, because manufacturers could pair different wheel and tire specifications within the same model year. Gardner 85 Series is especially important to check carefully because two different size formats appear for 1928, including an antique-style size where the first number is not the wheel diameter. Before choosing a tire, confirm the actual rim diameter on the car and compare it to the wheel and tire currently fitted.

Gardner 85 Series Tire Size Guide

Gardner 85 Series uses 2 distinct tire sizes across the 1928 model year. One of those sizes uses an antique diameter-by-section format, where the leading number gives the tire's outside diameter rather than the wheel diameter. That distinction matters here, because a size written with a large leading number can look like a wheel size when it is not.

31X6.001928Antique diameter-by-section

31X6.00 is listed for 1928 Gardner 85 Series and represents one of the year-specific fitment choices used on that model. In this format, 31 is the tire's approximate outside diameter in inches and 6.00 is the nominal section width, while the actual rim diameter must be confirmed from the wheel because it is not stated in the size code. Choose 31X6.00 only if the car is already fitted for that specification and the wheel dimensions match; a tube is required.

600-191928Numeric bias-ply

600-19 is also listed for 1928 Gardner 85 Series and is the size with a currently available tire offering. In numeric bias-ply sizing, 600 indicates a nominal 6.00-inch section width and 19 is the rim diameter, with the available product built for a 19-inch wheel. Choose 600-19 when the car carries 19-inch rims and that size matches the wheel and existing fitment; a tube is required.

Gardner 85 Series Tires by Year

The year listing shows which tire sizes are associated with each Gardner 85 Series model year and is the quickest way to narrow the choices on a specific car. In 1928, more than one size is listed, so the wheel and existing tire specification need to be checked before settling on a replacement. The leading number in 31X6.00 is the tire's outside diameter, not the wheel size, so the rim diameter must be confirmed separately.

Frequently Asked Questions

The Gardner 85 Series FAQ focuses on the 1928 size split, how antique and numeric sizes differ, and what to verify on a pre-war car before choosing a bias-ply tire.

Size Basics & Fitment

Gardner 85 Series uses two tire sizes in the 1928 model year: 31X6.00 and 600-19. The 600-19 size fits a 19-inch rim, while 31X6.00 is an antique diameter-by-section size in which the first number refers to overall tire diameter rather than wheel diameter, so its rim diameter cannot be read from the size code itself.

That means the correct choice depends on the specific wheels fitted to the individual Gardner 85 Series, not just the model year alone. Start by reading the size on the tire already on the car, then verify the wheel diameter directly before matching a replacement size.

On a Gardner 85 Series, 31X6.00 is an antique-style tire size. The 31 indicates the tire's approximate outside diameter in inches, and the 6.00 indicates its nominal section width, so the code does not tell you the wheel diameter the way a later 600-19 size does.

That format often causes confusion because modern buyers naturally assume the first number is the rim size. On a Gardner 85 Series, anyone considering 31X6.00 should measure or confirm the wheel itself before choosing a tire, especially on a restored car that may have had wheels changed during its life.

A 1928 Gardner 85 Series has two tire sizes listed because more than one wheel and tire specification appears within that model year. The listed sizes are 31X6.00 and 600-19, and they are not simply two ways of writing the same thing because one is an antique diameter-by-section size and the other is a numeric rim-diameter size.

The practical takeaway is that year alone is not enough to choose correctly for a 1928 Gardner 85 Series. Check the tire size already fitted, inspect the wheel diameter, and compare both against any restoration paperwork or marque references tied to the specific car.

Gardner 85 Series fitments in the listed year are bias-ply era sizes, including 31X6.00 and 600-19, and that style of collector tire should be treated as a tube-type application unless the wheel and tire are specifically built otherwise. The available 600-19 product is a bias-ply tire, which aligns with tube-required pre-war fitment practice.

On a Gardner 85 Series, tube condition matters just as much as the outer casing because an old or mismatched tube can create trouble even with a fresh tire. When fitting replacement tires, inspect the wheel interior, flap requirements, and valve stem compatibility so the assembly matches the period-style construction.

Buying the Right Tire

The correct size for a 1928 Gardner 85 Series is confirmed by matching the car's actual wheel and existing fitment to one of the two listed sizes: 31X6.00 or 600-19. Because 31X6.00 does not reveal rim diameter in the code, while 600-19 clearly fits a 19-inch rim, the first job is identifying which wheel specification the car actually has.

Begin with the wheels on the car rather than the model year alone. A restorer or owner should read any remaining sidewall markings, measure rim diameter carefully, and compare that information with period service material or marque-specific references tied to the individual Gardner 85 Series.

The listed Gardner 85 Series tire offering in 600-19 is available with a wide whitewall sidewall style. No other sidewall style appears in the current size listing tied to this model group.

For a 1928 Gardner 85 Series, sidewall appearance is part of the car's visual character as much as the size itself. If presentation and period look matter, compare the whitewall treatment on the car now with restoration photos, surviving original examples, or judging guidance before finalizing the tire style.

The currently listed Gardner 85 Series product is from Lester. That offering appears in size 600-19 and uses Lester Classic Bias Ply construction.

Brand matters less than getting the size, construction type, and wheel match right on a pre-war Gardner 85 Series. Once the correct size is confirmed, the next step is making sure the tire's visual style and overall character suit the level of restoration, touring, or show presentation the car is intended for.

Maintenance & Longevity

A Gardner 85 Series should be stored in a cool, dry, dark space with the tires kept away from sunlight, ozone sources, solvents, and standing moisture. On a pre-war car with bias-ply tires and tube-type assemblies, long periods of inactivity can create flat spotting and place extra stress on old casings, tubes, and wheel hardware.

Reduce those effects by keeping inflation appropriate for storage, moving the car periodically, or using methods that take some load off the tires during extended display periods. Owners of a Gardner 85 Series should also inspect sidewalls and valve stems regularly because collector cars often age out tires long before tread wears down.

Tires on a Gardner 85 Series should be visually inspected before every drive and given a closer hands-on inspection at regular intervals even if the car sees very little mileage. A pre-war bias-ply setup deserves special attention to sidewall cracking, tread separation signs, bead condition, tube-related air loss, and any irregular wear that suggests wheel or chassis issues.

That routine matters because low-use collector cars often hide age problems until the first road outing. A Gardner 85 Series that is shown, toured occasionally, or kept in long-term storage benefits from seasonal inspection by someone familiar with antique tire and wheel assemblies, not just modern passenger car service.

A Gardner 85 Series tire should be replaced when age, cracking, casing distortion, hardening rubber, repeated air loss, or other condition issues appear, even if the tread still looks usable. Tread depth alone is a poor guide on collector cars because time, storage conditions, and internal deterioration often matter more than mileage.

That rule applies even more strongly to pre-war applications and to any period tire that has spent decades in storage. If a Gardner 85 Series ever carries an older original or long-stored tire, specialist evaluation is wise before any road use, since appearance alone cannot judge internal condition.

Restoration & Authenticity

Gardner 85 Series is associated here with two 1928 fitment sizes: 31X6.00 and 600-19. The available current product is a Lester Classic Bias Ply in 600-19, but the listed size range indicates that more than one period-style specification was used within the model year.

For an exact restoration, the right answer comes from the individual Gardner 85 Series rather than the model name alone. Original owner material, surviving unrestored examples, and marque-specific references are the best way to confirm which of the listed sizes belongs on a particular chassis or body configuration.

Correct tire fitment can absolutely affect how a Gardner 85 Series is judged and perceived, especially on a car from the late 1920s where wheel diameter, sidewall presentation, and overall tire profile are visually prominent. A tire that is the wrong size or wrong visual style can change stance, fender fill, and the period character of the car.

That makes fitment more than a simple maintenance decision on a Gardner 85 Series. Owners pursuing authenticity should compare size, sidewall appearance, and construction style with period references and club judging expectations so the tire choice supports both the car's look and its historical credibility.

The listed Gardner 85 Series offering uses a wide whitewall sidewall style in 600-19. On a 1928 luxury-era automobile, sidewall appearance is a major part of the finished look, and whitewall treatment often changes the visual balance of the entire car.

The correct choice for a Gardner 85 Series restoration depends on the exact presentation goal: preservation, period-style touring, or concours-level accuracy. Comparing the car to period photos, sales literature, and recognized marque examples is the best way to decide whether the available wide whitewall look matches the car's intended historical finish.

Safety & Road Use

A properly fitted, sound-condition tire can make a Gardner 85 Series suitable for cautious public-road use within the limits of a late 1920s automobile. Safety depends on much more than the tire alone, because braking, steering, wheel condition, suspension wear, and tube integrity all play a major role on a pre-war car.

Owners should treat a Gardner 85 Series as an antique road car rather than a modern traffic machine. Sensible route planning, conservative speeds, and a full mechanical check before driving are part of using the car responsibly, especially if it has been stored for long periods or recently returned to service.

Before driving a Gardner 85 Series, check tire inflation, visible sidewall condition, valve stems, wheel security, and any signs of tube-related leakage or casing distortion. On a car with 1928-era bias-ply fitment, it is also wise to inspect steering response, brake operation, and wheel bearings before putting the car into regular motion.

Those checks matter because antique cars often sit longer than they run, and dormant problems tend to appear on the first outing. A Gardner 85 Series should be driven only after the tire size and wheel match are confirmed and the rest of the chassis is in equally trustworthy condition.

A Gardner 85 Series should be driven at moderate, conservative speeds that respect both the car's age and the behavior of bias-ply, tube-type tires. Even with correctly fitted tires, a late 1920s automobile has different braking distances, steering feel, and stability margins than a modern vehicle, so speed should always be matched to road conditions and mechanical condition.

The practical approach is to drive a Gardner 85 Series in a way that leaves a wide safety margin rather than chasing modern traffic flow. Smooth inputs, lower cruising speeds, and extra caution on heat, rough pavement, and long descents will do more for safety than any single specification on the tire sidewall.
