The 1928 Gardner 95 Series comes from an era when independent automakers competed on engineering quality, road manners, and upscale presentation rather than sheer production volume. For owners of a surviving Gardner, tire choice is part preservation and part practical road-readiness, because the right dimensions shape both stance and drivability. This model uses bias-ply fitments in 30X6.20 and 650-18, centered around an 18-inch wheel setup. Within 650-18, there are traditional Firestone Balloon options with either blackwall or wide whitewall styling. The key is confirming which of the two period fitments is on the car now and matching the tire to the wheel, appearance, and intended use.
Which Tire Size Is Right for The 1928 Gardner 95 Series
The 1928 Gardner 95 Series uses two primary tire sizes, and both are bias-ply fitments associated with the covered 8 Cyl. configuration. Before selecting a tire, confirm which size is actually on the car and verify the wheel setup, because the decision is not just about appearance but about matching the tire to the correct rim and overall period-style fitment.
30X6.20 is an antique diameter-by-section size, meaning the first number reflects an approximate overall tire diameter of 30 inches and the second number refers to an approximate section width of 6.20 inches. It is a bias-ply fitment suited to the late-1920s tire sizing language that many modern buyers do not see often. On a 1928 Gardner 95 Series, this size is part of the original-style fitment conversation rather than a modern radial substitution path. It is best evaluated by confirming the wheel on the car and comparing the existing tire dimensions before replacing a complete set.
650-18 is a numeric bias-ply size in which 650 denotes an approximate 6.50-inch nominal section width and 18 identifies the rim diameter. On the 1928 Gardner 95 Series, it represents a traditional period tire format for an 18-inch wheel and is the size with available Firestone Balloon choices. Those options include blackwall and wide whitewall sidewall treatments, which gives the owner some freedom in how formal or understated the finished car appears. This size deserves a closer look when the goal is to balance correct vintage character with an appearance choice that suits the restoration.
Sub-model fitment is straightforward here because the covered 1928 Gardner 95 Series 8 Cyl. uses the same two primary bias-ply sizes. The important step is confirming which of those period sizes is mounted on the car before choosing a replacement tire.

1928 Gardner 95 Series 8 Cyl.
The 1928 Gardner 95 Series 8 Cyl. uses the same pair of primary bias-ply fitments found at the model level, so the main question is which size the car is wearing now. That makes tire selection more about wheel confirmation, period-style presentation, and choosing the right replacement within the correct vintage format.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 1928 Gardner 95 Series Tires for Sale
Available 650-18 choices focus on Firestone Balloon bias-ply tires, with both blackwall and wide whitewall presentations. That makes the product comparison less about construction and more about sidewall style, load specification where stated, and matching the tire's look to the car's restoration direction.
Owners of a 1928 Gardner 95 Series usually need to sort out which of the two vintage tire sizes is on the car, how the 18-inch wheel setup affects selection, and what to inspect before putting an older collector car back on the road.
Tire Size & Fitment
What tire size fits a 1928 Gardner 95 Series?
The 1928 Gardner 95 Series uses two primary bias-ply tire sizes: 30X6.20 and 650-18. Both sizes are associated with the covered 1928 Gardner 95 Series 8 Cyl., so the correct choice depends on which period fitment is on the car rather than on a separate radial-versus-bias primary setup.
The practical next step is to inspect the tires and wheels already mounted on the vehicle. A car that now carries 650-18 tires should stay within that size family unless the wheel setup is being changed, while a car using 30X6.20 should be replaced with careful attention to overall vintage dimensions and wheel compatibility.
What size rim does a 1928 Gardner 95 Series use?
The 1928 Gardner 95 Series is centered around an 18-inch rim diameter. That is stated directly with the 650-18 fitment, and the model-level fitment summary also points to an 18-inch wheel setup for this vehicle.
Rim diameter should be confirmed on the actual car before ordering tires, especially on a collector vehicle that may have had wheel changes over the decades. Checking the wheel itself, the existing tire markings, and the current rim width helps prevent choosing a vintage size that looks right on paper but does not suit the mounted wheel.
What does 650-18 mean on a 1928 Gardner 95 Series?
650-18 is a numeric bias-ply tire size. The 650 portion refers to an approximate 6.50-inch nominal section width, and the 18 identifies the rim diameter in inches, which places it squarely in the vintage sizing language used on late-1920s automobiles.
For a Gardner owner, that means the tire should be chosen with the wheel dimensions and the car's intended presentation in mind. Since 650-18 is available in Firestone Balloon form with different sidewall treatments, the decision can include both fitment accuracy and whether the car calls for a blackwall or wide whitewall appearance.
Choosing the Right Tire
What should I consider when choosing a 650-18 tire for a 1928 Gardner 95 Series?
Start with the basics: confirm that the car actually uses 650-18 rather than 30X6.20, then check that the wheel is an 18-inch rim in the proper width range for the tire being considered. Since the available 650-18 products are bias-ply Firestone Balloon tires, construction is consistent and appearance becomes a more meaningful part of the choice.
Selection usually comes down to sidewall style, the look desired for the finished car, and whether the stated load figure matters for how the vehicle will be used. A well-preserved driver may call for one presentation, while a restoration with stronger period styling may lean toward another, provided the wheel and overall fitment remain correct.
What sidewall styles are available for 1928 Gardner 95 Series tires?
In 650-18, the available sidewall styles include blackwall and wide whitewall. Both appear in the Firestone Balloon line, giving the 1928 Gardner 95 Series owner a choice between a more restrained vintage look and a more formal period-style presentation.
That choice affects appearance more than fitment, but it is still worth confirming the exact tire size before deciding on style. A wide whitewall can change the car's visual character significantly, so buyers who are aiming for a restoration-oriented result often compare sidewall treatment just as carefully as they compare the size itself.
What brands offer tires for the 1928 Gardner 95 Series?
The currently available products for the 1928 Gardner 95 Series in 650-18 come from Firestone. They are part of the Firestone Balloon series, with options that differ mainly by sidewall treatment and related product specifications rather than by a change in basic construction.
That means the buying decision is less about choosing among several brands and more about selecting the right Firestone Balloon version for the car's needs. Confirming size, wheel dimensions, and desired appearance will matter more than brand comparison when narrowing down the correct vintage-style tire for this application.
Restoration & Appearance
Which tire should I choose for a period-style 1928 Gardner 95 Series?
A period-style 1928 Gardner 95 Series should begin with the correct primary fitment family for the car, which means confirming whether it uses 30X6.20 or 650-18. Both are bias-ply vintage sizes, so the first restoration decision is preserving the proper size and wheel relationship before comparing appearance details.
Once the size is confirmed, the visible character of the tire becomes more important. In 650-18, Firestone Balloon options include blackwall and wide whitewall styles, each creating a different presentation. Buyers seeking exact historical authenticity should still compare their car against marque references, period photos, or restoration records before settling on one sidewall treatment.
Does correct tire fitment matter for a 1928 Gardner 95 Series restoration?
Correct tire fitment matters a great deal on a 1928 Gardner 95 Series because tire size strongly affects stance, wheel fill, and the overall visual balance of a prewar-era automobile. Using the proper vintage size format also helps preserve the character of the car rather than making it look visually out of period.
Fitment is not only about appearance, though. A restoration-minded owner should also confirm wheel diameter, rim width, and the size currently mounted before replacing tires, especially if the car has passed through several owners. Getting those fundamentals right supports both the look of the car and its practical road-readiness.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1928 Gardner 95 Series?
Yes, modifications can affect tire fitment on a 1928 Gardner 95 Series, even when the change seems minor. Different wheels, altered rim widths, suspension work, or body and fender changes can all influence whether a vintage-size bias-ply tire sits correctly and clears the car as intended.
That is especially important on older collector cars that may have been updated at some point in their lives. A replacement tire should be matched to the car as it sits today, not just to the model name. Checking wheel dimensions, tire-to-fender clearance, and steering movement helps avoid problems after installation.
What should I inspect before driving a 1928 Gardner 95 Series on new tires?
Before road use, inspect the wheel condition, valve stems, mounting hardware, and the tires themselves for proper seating and inflation. On the rest of the car, look closely at steering play, brake operation, suspension condition, and anything that could cause uneven loading or unwanted contact once the Gardner is moving.
A short local test drive is a smart way to confirm that the car tracks properly and that nothing rubs under steering or road movement. Collector vehicles often spend long periods parked, so it is also wise to recheck air pressure and look for any early signs of shifting, scuffing, or air loss after the first miles.
How should 650-18 tires on a collector 1928 Gardner 95 Series be maintained?
650-18 tires on a collector 1928 Gardner 95 Series should be maintained with regular pressure checks, visual inspection, and careful storage habits. Watch for sidewall cracking, cuts, bulges, uneven wear, and slow air loss, since older cars are often driven infrequently and tire issues can go unnoticed between outings.
Storage conditions matter almost as much as road use. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources can help preserve the tires between drives. It also helps to move the vehicle periodically or adjust how it is parked so the tires are not left carrying the same load in one spot for too long.
