The 1973 BMW 2500 came from BMW’s influential New Six sedan family, a car that helped define the brand’s reputation for refined highway manners and understated sporting character. Owners today often want tires that preserve that balanced feel without losing the right visual proportion on a 14-inch wheel. For this exact model, the primary fitments are radial, with 175R14 and DR70-14 both associated with the car. That creates a choice between a familiar Euro-metric radial format and a vintage alphanumeric radial format, along with differences in brand and tire series within 175R14. The right selection starts with the size you intend to run, then moves to appearance, wheel compatibility, and how original or road-focused the car will be.
Which Tire Size Is Right for The 1973 BMW 2500
The 1973 BMW 2500 uses two primary tire sizes, and both are radial fitments on a 14-inch rim. Because the covered sub-models share these same sizes, the main decision is not trim level but which size format and tire style best match your wheels, appearance goals, and intended driving use.
A 175R14 tire uses a 175-millimeter nominal section width, radial construction, and a 14-inch rim diameter, with this format commonly associated with an 80-series profile. On a 1973 BMW 2500, it matches the car’s European sizing language and keeps the fitment in a radial construction that suits a sedan of this era. Available choices include Michelin and Vredestein products in blackwall form, with series such as Michelin XAS, Sprint Plus, and Sprint Classic. This size is the practical starting point for owners who want a period-appropriate metric radial presentation with several product-character options.
DR70-14 is an alphanumeric radial size in which the letter code identifies the size class, the 70 denotes the profile family, and the 14 identifies the wheel diameter. For the 1973 BMW 2500, it represents a vintage-style radial sizing convention rather than a modern P-metric format, which can matter to owners who prefer an era-appropriate look in the sidewall marking itself. Its role is different from the 175R14 metric presentation, even though both sizes use the same 14-inch rim diameter. Choosing between them starts with the wheel setup on the car and the type of visual character you want the tire to carry.
Fitment is straightforward across the covered 1973 BMW 2500 sub-model range, because the same primary tire sizes are associated with each one. That means sub-model identification matters less than confirming which of the two radial size formats you want to run on the car.

Best 1973 BMW 2500 Tires for Sale
Current 175R14 choices for the 1973 BMW 2500 focus on radial blackwall tires from Michelin and Vredestein. The main comparisons are between series such as Michelin XAS, Sprint Plus, and Sprint Classic, along with rim-width compatibility and other product-level specifications.
These FAQs focus on the 1973 BMW 2500’s two radial tire sizes, 14-inch rim fitment, product choices within 175R14, and the checks that matter before putting a restored or regularly driven car back on the road.
Tire Size & Fitment
What tire size fits a 1973 BMW 2500?
The 1973 BMW 2500 uses two primary radial tire sizes: 175R14 and DR70-14. Both sizes are associated with the car on a 14-inch rim, and the covered Base, A & Bavaria grouping shares those same fitments rather than splitting by separate sub-model size assignments.
That means the first step is deciding which of those two size formats matches the wheel and presentation you want to use. A 175R14 follows a Euro-metric radial convention, while DR70-14 uses a vintage alphanumeric radial format, so wheel diameter, wheel width, and the overall look of the car should all be checked before making the final selection.
What size rim does a 1973 BMW 2500 use?
The tire fitments associated with the 1973 BMW 2500 use a 14-inch rim diameter. That applies to both 175R14 and DR70-14, so the two primary tire sizes share the same wheel diameter even though their size codes follow different radial sizing conventions.
Rim diameter is only part of the fitment picture, so it is still worth confirming the actual wheel width on the car before choosing a tire. On collector BMWs, wheel changes are common over the years, and an aftermarket wheel or a non-original wheel width can affect which tire option is the better match.
Do all 1973 BMW 2500 sub-models use the same tire size?
Yes. The covered 1973 BMW 2500 Base, A & Bavaria sub-model grouping shares the same tire-size pattern, with both 175R14 and DR70-14 associated with those cars. There is not a separate primary size assignment within that covered group that changes by sub-model name.
That simplifies shopping, because the decision moves away from trim identification and toward the actual wheel and tire setup on the car in front of you. A BMW that has been restored, modified, or fitted with later wheels should still have its rim width and overall clearance checked before choosing between the two radial size formats.
Choosing the Right Tire
What should I consider when choosing a 175R14 tire for a 1973 BMW 2500?
Start with the basics: 175R14 should match a 14-inch wheel, radial construction, and the kind of period-oriented metric sizing many owners want on a 1973 BMW 2500. Within that size, available choices vary by brand and series, including Michelin XAS and Vredestein offerings such as Sprint Plus and Sprint Classic.
After size confirmation, compare the wheel-width compatibility and the overall character you want from the tire. Some owners prioritize a more traditional European touring appearance, while others focus on a blackwall radial that suits regular road use. Product weight and load details can also help narrow the choice once the size and wheel match are confirmed.
What sidewall styles are available for 1973 BMW 2500 tires?
The available 175R14 products for the 1973 BMW 2500 use a blackwall sidewall style. That keeps the appearance restrained and appropriate for a European sedan of this era, without introducing a whitewall, redline, or raised-letter treatment that would significantly change the car’s visual character.
For many owners, that makes selection more about brand, series, and sizing format than about decorative sidewall treatment. A blackwall radial suits both a road-driven car and a restoration-oriented presentation, but the final look still depends on wheel finish, ride height, and whether the car is being preserved in a stock-style appearance or updated subtly.
What brands offer tires for the 1973 BMW 2500?
Michelin and Vredestein both offer applicable 175R14 radial tires for the 1973 BMW 2500. The current group includes Michelin XAS and Vredestein series such as Sprint Plus and Sprint Classic, giving the car more than one brand path within the correct metric radial size.
The better way to choose between them is to compare the specific tire series, wheel-width suitability, and the kind of driving or presentation you expect from the car. One owner may prefer a classic European touring look, while another may focus on the particular specifications attached to a given 175R14 product rather than brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1973 BMW 2500?
A period-style starting point for a 1973 BMW 2500 is usually one of its primary radial sizes, with 175R14 often appealing to owners who want a classic European metric presentation. DR70-14 can also be relevant when a vintage alphanumeric radial format better suits the way the car is being presented.
Appearance goals matter as much as fitment here, especially on a restored sedan where tire proportions strongly affect the stance. Blackwall 175R14 options from Michelin and Vredestein keep the look understated, but exact originality questions are best checked against marque references, archival photos, and vehicle-specific restoration documentation.
Does correct tire fitment matter for a 1973 BMW 2500 restoration?
Yes, correct tire fitment has a major effect on how a restored 1973 BMW 2500 looks and drives. The right size influences sidewall shape, wheel-to-tire proportion, and the visual balance of the car, while the correct radial sizing format helps keep the presentation consistent with the car’s era.
Restoration-minded owners should look beyond simple rim diameter and confirm the exact tire size, wheel width, and overall appearance they want to preserve. Even when a tire is associated with the model, later wheel changes or a modified ride height can alter the result, so the actual setup on the car deserves a careful check before installation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1973 BMW 2500?
Yes. A 1973 BMW 2500 may share its primary tire sizes across the covered sub-models, but modifications can still change what works on the individual car. Aftermarket wheels, different wheel widths, altered ride height, suspension work, or body changes can all influence how a 175R14 or DR70-14 sits in the wheel opening.
That is why the actual wheel and chassis setup should be checked before assuming a familiar size remains the best choice. Steering clearance, fender clearance, and the relationship between tire width and wheel width all deserve attention, especially on a vintage BMW that may have had several decades of parts changes or restoration work.
What should I inspect before driving a 1973 BMW 2500 on new tires?
Before road use, inspect the wheel condition, confirm the tire size and rim diameter match, and make sure each tire is mounted and inflated correctly. It is also wise to look over the suspension, steering, and brake components, because a fresh set of tires can reveal looseness or alignment issues that were less obvious before.
A short initial drive should include checking for rubbing, vibration, and unusual pull through the steering wheel. On a collector BMW, it also helps to recheck air pressure after the first miles and confirm that the car tracks cleanly, since long storage, prior wheel changes, or aged chassis parts can affect how the new tires behave.
How should 175R14 tires on a collector 1973 BMW 2500 be maintained?
Collector-car tires should be maintained with regular pressure checks, visual inspections, and attention to age-related condition even when tread wear is minimal. On a 1973 BMW 2500 running 175R14 tires, look for cracking, bulges, cuts, irregular wear, or signs of air loss, especially if the car spends long periods parked.
Storage conditions matter almost as much as mileage on a low-use car. Keeping the BMW away from prolonged sunlight, excessive heat, moisture, and ozone sources can help preserve the tires, and occasional movement of the car can reduce long-term flat-spotting. Any sign of deterioration deserves a closer inspection before longer road use.
