The 1973 BMW 2800 belongs to the era when BMW coupes and sedans were earning a reputation for crisp road manners, restrained styling, and a distinctly European touring character. Owners today often want tires that preserve that balanced feel without losing the visual character that suits an early-1970s BMW. This model uses 14-inch radial fitments, with 175R14 and DR70-14 both associated with the car. Available choices in the 175R14 family include blackwall radial options from Michelin and Vredestein across several series. The key is matching the tire to the car's exact setup, intended use, and the appearance expected from a well-kept or restoration-oriented BMW.
Which Tire Size Is Right for The 1973 BMW 2800
The 1973 BMW 2800 uses two radial tire sizes, and both are built for a 14-inch rim. Because the same covered sub-model grouping is associated with 175R14 and DR70-14, the first step is confirming the exact wheel and tire setup currently on the car. After that, the decision shifts toward selecting the right radial style, construction presentation, and product series for the way the BMW is driven and maintained.
175R14 is a Euro-metric radial size in which 175 refers to nominal section width in millimeters, R identifies radial construction, and 14 is the wheel diameter in inches. On a 1973 BMW 2800, this format suits the car's European character and keeps the focus on a traditional metric radial presentation. Available choices include blackwall offerings from Michelin and Vredestein in XAS, Sprint Plus, and Sprint Classic lines. This size is a strong place to start when the goal is retaining a proper vintage-European look while choosing among established radial tire series.
DR70-14 is an alphanumeric radial size, with the letter designation identifying the tire's vintage size class, the 70 marking its profile family, and 14 indicating the wheel diameter. For a 1973 BMW 2800, it represents a period radial sizing convention that differs from the more familiar Euro-metric format. That makes wheel and overall setup confirmation especially important before selecting tires around this fitment. Buyers considering this size should verify that the car is still using the same 14-inch wheel arrangement associated with the alphanumeric radial format.
Fitment is straightforward in one sense because the covered 1973 BMW 2800 sub-model grouping stays within 14-inch radial tire fitments. The important detail is that more than one tire size is associated with that grouping, so checking the actual wheel and tire setup on the car matters before choosing a replacement.

If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 1973 BMW 2800 Tires for Sale
Current 175R14 choices for the 1973 BMW 2800 center on blackwall radial tires from Michelin and Vredestein. The available options differ by tire series, weight, and rim-width compatibility, which makes the product grid useful for comparing both period-style appearance and practical wheel match.
These FAQs focus on the tire sizes used on the 1973 BMW 2800, 14-inch rim fitment, radial tire selection, period-style appearance, and the basic checks worth making before putting a collector-era BMW back on the road.
Tire Size & Fitment
What tire size fits a 1973 BMW 2800?
The 1973 BMW 2800 is associated with two radial tire sizes: 175R14 and DR70-14. Both sizes are intended for 14-inch wheels, so the car stays within one rim diameter even though the sizing formats differ between Euro-metric radial and vintage alphanumeric radial.
The practical step is checking what is actually mounted on the car now, especially on a collector BMW that may have changed wheels or tires over time. Once the existing setup is confirmed, the choice becomes less about wheel diameter and more about selecting the correct size format, radial style, and product series for the car's appearance and road use.
What size rim does a 1973 BMW 2800 use?
The tire sizes associated with the 1973 BMW 2800 use a 14-inch rim diameter. That applies to both 175R14 and DR70-14, so the main rim-diameter question is fairly simple even though the vehicle can be encountered with more than one tire-size format.
Rim diameter is only one part of fitment, so it is still worth checking actual wheel width and the tire currently on the car before choosing replacements. A restored or modified BMW may no longer be wearing its earlier wheel setup, and that can affect which radial tire option makes the most sense for safe clearance and proper appearance.
Do all 1973 BMW 2800 sub-models use the same tire size?
The covered 1973 BMW 2800 A, CS & CSA grouping is associated with the same two radial tire sizes, 175R14 and DR70-14. That means the sub-model grouping stays within one overall 14-inch fitment family rather than splitting into separate wheel diameters.
Even with that shared fitment pattern, it is still wise to confirm the exact tire and wheel package on the individual car. Older BMWs are often maintained, restored, or updated over time, and that can change the size actually in service. Verifying the current setup helps avoid choosing a tire in the wrong sizing convention.
Choosing the Right Tire
What should I consider when choosing a 175R14 tire for a 1973 BMW 2800?
Start with the basics: correct 175R14 sizing, radial construction, and compatibility with the car's 14-inch wheel. Then compare the available tire series, including Michelin XAS and Vredestein Sprint Plus or Sprint Classic, along with product details such as blackwall appearance, rim-width range where stated, and overall tire weight.
The right choice depends on how the BMW is used and how closely the owner wants to maintain a vintage-European presentation. A touring-oriented driver may focus on road manners and wheel compatibility, while a restoration-minded owner may care more about period-style visual character. Matching the tire to the actual wheel and the car's intended use is the smart next step.
What sidewall styles are available for 1973 BMW 2800 tires?
The available 175R14 products for the 1973 BMW 2800 are blackwall radials. That keeps the appearance restrained and appropriate for a European car of this period, rather than introducing whitewall, redline, or raised-letter sidewall treatments that create a very different visual effect.
Sidewall style matters because it changes the entire stance and presentation of the car even when the size is correct. On a BMW 2800, blackwall tires usually support a clean, understated look. Once the sidewall style is settled, the remaining comparison points are tire series, wheel compatibility, and whether the car is meant for regular road use or a more preservation-focused role.
What brands offer tires for the 1973 BMW 2800?
Michelin and Vredestein both offer applicable 175R14 radial tires for the 1973 BMW 2800. Within those brands, the available series include Michelin XAS plus Vredestein Sprint Plus and Sprint Classic, giving the buyer more than one way to approach vintage radial fitment on a 14-inch wheel.
Brand choice should not be separated from the rest of the fitment picture. It helps to compare the exact tire series, sidewall presentation, stated rim-width range when available, and the overall character the owner wants from the car. That approach is more useful than choosing by brand name alone, especially on a collector-era BMW with specific visual and road-use priorities.
Restoration & Appearance
Which tire should I choose for a period-style 1973 BMW 2800?
A period-style 1973 BMW 2800 usually starts with the correct 14-inch radial fitment and an appearance that suits an early-1970s European car. The 175R14 size is especially useful here because it is available in blackwall radial form from Michelin and Vredestein, which keeps the presentation traditional rather than overly modern.
The best period-style choice depends on whether the goal is road use, show presentation, or a balance of both. Exact originality questions should be checked against marque references and vehicle-specific historical sources. For most buyers, preserving the proper size family, blackwall look, and a vintage-appropriate radial profile is the most practical starting point.
Does correct tire fitment matter for a 1973 BMW 2800 restoration?
Correct tire fitment matters because the wrong size or sizing format can change how a restored 1973 BMW 2800 looks on the road and how naturally it sits on its wheels. Staying within the known 14-inch radial fitments helps keep the car visually coherent with its era and intended character.
Fitment also affects practical details beyond appearance. Wheel width, tire profile, and the actual setup on the car all deserve a quick check before a replacement is chosen. That is especially important on older restorations, where wheels or suspension parts may have changed over time even when the car still appears outwardly stock.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1973 BMW 2800?
Yes, modifications can affect tire fitment on a 1973 BMW 2800 even when the car still uses a 14-inch wheel. Changes to wheel width, offset, suspension height, springs, or body clearance can alter which tire size works comfortably and which size format makes sense on the finished setup.
That is why the car should be checked as it sits today rather than relying on assumptions from age alone. A BMW with aftermarket wheels or suspension changes may need closer attention to clearance at the fenders and steering components. Confirming the actual setup before ordering tires helps avoid surprises once the tires are mounted.
What should I inspect before driving a 1973 BMW 2800 on new tires?
Before putting a 1973 BMW 2800 back on the road with new tires, inspect the wheels, valve stems, and the basic condition of the suspension and steering components. It also makes sense to confirm that the tire size on the car matches the intended replacement and that there is no visible interference at full steering lock.
A short road test should be approached carefully while monitoring air retention, vibration, and any rubbing that appears under turning or suspension movement. Tire pressure should be set appropriately for the application, and the rest of the car deserves attention too, especially on a low-use collector vehicle that may have aged mechanically between drives.
How should 175R14 tires on a collector 1973 BMW 2800 be maintained?
175R14 tires on a collector 1973 BMW 2800 should be checked regularly for pressure, tread condition, sidewall cracking, cuts, bulges, and signs of slow air loss. Even a car that is driven sparingly can develop tire issues through age, storage conditions, or long periods of sitting in one position.
Good maintenance also includes storing the car away from prolonged sunlight, heat, moisture, and ozone sources when possible. During the driving season, a quick visual inspection before longer trips is worthwhile, especially on an older BMW that may spend weeks between outings. Consistent checks help protect both the tire investment and the car's road manners.
