The 1973 BMW 3.0 sits in the era that established BMW’s grand touring reputation, blending crisp coupe styling with the kind of high-speed road manners that made these cars stand out in period. Tire choice matters on a car like this because the right size supports both its stance and the way it feels on the road. Fitment centers on 14-inch radial tires, with 175R14 and 195/70R14 both appearing depending on the sub-model. That opens the door to choices in vintage European-style radial sizing, modern metric sizing, and brand-specific tire character. The key is matching the exact sub-model and wheel setup before deciding between restoration-minded appearance and regular road use priorities.
Which Tire Size Is Right for The 1973 BMW 3.0
Two tire sizes apply to the 1973 BMW 3.0, and the right choice depends first on the exact sub-model. Both sizes are radial tires for 14-inch rims, but they are not used across every 3.0 variant in the same way. Before choosing a tire, confirm whether the car is a 3.0 CS or CSA, or a 3.0 S or SA, and then compare the available tire style, brand, and sizing format within that fitment.
A 195/70R14 is a metric radial size that spells out its key dimensions more directly: 195 millimeters in section width, a 70-series aspect ratio, radial construction, and a 14-inch rim. On the 1973 BMW 3.0, this size appears on more than one sub-model and represents a more modern metric format than 175R14. The available product is a Dunlop Sport Classic with a blackwall sidewall, giving the car a clean road-oriented look. This size deserves a close look when the goal is maintaining correct sub-model fitment within a later-style radial sizing convention.
Sub-model identification matters on the 1973 BMW 3.0 because tire fitment is not identical across the range. The coupe-oriented 3.0 CS and CSA can use either listed size, while the 3.0 S and SA use only one, so confirming the exact badge helps narrow the correct tire choice quickly.

1973 BMW 3.0 CS & CSA
The 1973 BMW 3.0 CS and CSA have the broadest fitment range here, with both 175R14 and 195/70R14 appearing as radial options on 14-inch rims. That gives the buyer a meaningful choice between a more traditional Euro-metric look and a more explicit modern metric size, while still requiring wheel and clearance confirmation on the actual car.
The 1973 BMW 3.0 S and SA use 195/70R14 radial tires on 14-inch rims. Tire selection is therefore more straightforward, and the decision shifts from size identification to choosing the right product character for the car’s appearance, intended road use, and existing wheel setup.
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 1973 BMW 3.0 Tires for Sale
Available 1973 BMW 3.0 tires span Michelin, Vredestein, and Dunlop, all in blackwall radial construction for 14-inch applications. The main comparison points are size format, tire series, and rim-width compatibility, especially within the 175R14 choices.
These FAQs focus on the 1973 BMW 3.0’s two radial tire sizes, 14-inch rim fitment, sub-model differences, and the practical choices between vintage Euro-metric and modern metric tire options.
Tire Size & Fitment
What tire size fits a 1973 BMW 3.0?
The 1973 BMW 3.0 uses two radial tire sizes across its covered sub-models: 175R14 and 195/70R14. The 3.0 CS and CSA can use either of those sizes, while the 3.0 S and SA use 195/70R14.
That makes sub-model identification the first step before choosing a tire. Both sizes are built for 14-inch rims, but the sizing format and overall presentation differ, so it helps to confirm the exact car, the wheels currently on it, and whether the goal is a more traditional European-style fitment or a later metric radial format.
What size rim does a 1973 BMW 3.0 use?
Both tire sizes used on the 1973 BMW 3.0 are designed for 14-inch rims. That applies to the 175R14 and the 195/70R14 fitments, so the wheel diameter remains consistent even though the tire sizes vary by sub-model.
Rim diameter is only one part of fitment, so it is still smart to verify the actual wheels on the car before ordering tires. Many collector cars have seen wheel changes over the years, and width differences can affect how a tire sits, especially when comparing the 175R14 options that include published rim-width guidance.
Do all 1973 BMW 3.0 sub-models use the same tire size?
No, the 1973 BMW 3.0 does not use one universal tire size across all covered sub-models. The 3.0 CS and CSA can use 175R14 or 195/70R14, while the 3.0 S and SA are associated with 195/70R14 only.
That difference matters because a buyer cannot assume every 3.0 coupe or sedan-equivalent trim uses the same tire just because the wheel diameter matches. Checking the sub-model badge first keeps the decision focused and helps avoid choosing a tire format that suits another 3.0 variant better than the one actually in the garage.
Choosing the Right Tire
What should I consider when choosing a tire for a 1973 BMW 3.0?
Start with the correct size for the exact 1973 BMW 3.0 sub-model, then compare the tire’s construction, sizing format, and intended character. This car uses radial tires in either 175R14 or 195/70R14, both on 14-inch rims, so the main choice is not bias-ply versus radial but which radial format best matches the car.
After size is settled, look at brand, tire series, sidewall presentation, and wheel compatibility. A 175R14 buyer may focus on a more vintage European-style appearance, while a 195/70R14 buyer may be concentrating on a later metric radial setup. The existing wheel width and the car’s use pattern should guide the final decision.
What sidewall styles are available for 1973 BMW 3.0 tires?
The available tires for the 1973 BMW 3.0 are offered in blackwall sidewall style. That applies across the Michelin, Vredestein, and Dunlop products associated with the 175R14 and 195/70R14 sizes.
A blackwall presentation suits the restrained, European touring character many owners want from a 3.0. Since there is no sidewall-style split in the current fitment choices, the visual decision shifts toward tire series and size format instead, particularly if the car is being kept close to a period-style look without making unsupported originality assumptions.
What brands offer tires for the 1973 BMW 3.0?
Michelin, Vredestein, and Dunlop all have tires within the fitments used on the 1973 BMW 3.0. Michelin XAS, Vredestein Sprint Plus, and Vredestein Sprint Classic appear in 175R14-type fitments, while Dunlop Sport Classic covers the 195/70R14 option.
Brand alone should not decide the purchase, because each option also reflects a particular tire series and size format. It is better to begin with the correct sub-model fitment, then compare how each available series aligns with the car’s appearance goals, rim compatibility, and whether the owner wants a more vintage European-style presentation or a later metric look.
Restoration & Appearance
Which tire should I choose for a period-style 1973 BMW 3.0?
For a period-style 1973 BMW 3.0, the first step is keeping to the correct sub-model fitment and 14-inch radial format. Among the listed sizes, 175R14 has the more traditional Euro-metric appearance, while 195/70R14 reads as a more modern metric radial size.
That does not make one universally right for every restoration goal, since authenticity standards can vary by market, production date, and owner intent. Buyers aiming for a historically consistent look should compare the tire’s overall presentation, then check marque references or restoration documentation if exact originality matters beyond simply staying within the proper fitment family.
How does tire construction affect the appearance of a restored 1973 BMW 3.0?
On the 1973 BMW 3.0, construction has less visual impact than size format because the primary fitments here are all radial. The appearance difference comes more from whether the car wears a traditional Euro-metric 175R14 or a modern metric 195/70R14, along with the specific tire series chosen.
That means restoration-minded buyers can stay within radial construction while still shaping the car’s look in a meaningful way. A more classic European tire profile may better suit one project, while another owner may prefer the stance and road-going impression of the 195/70R14 setup, provided the choice matches the exact sub-model and wheel dimensions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1973 BMW 3.0?
Yes, modifications can affect tire fitment on a 1973 BMW 3.0 even when the nominal tire size is correct. Aftermarket wheels, altered wheel widths, suspension changes, ride-height changes, or bodywork differences can all influence how a 175R14 or 195/70R14 tire sits on the car.
That is especially important on collector cars that may have changed hands several times. A buyer should confirm the actual wheel diameter and width, then inspect steering and fender clearance at full lock and through suspension movement. Matching the tire size to the sub-model is important, but matching it to the car’s current physical setup matters just as much.
What should I inspect before driving a 1973 BMW 3.0 on new tires?
Before driving a 1973 BMW 3.0 on new tires, inspect the wheels for correct diameter and condition, then check that the tires are seated properly and inflated appropriately for the application. It also helps to look over the suspension, steering components, and alignment condition on a car of this age.
A short, careful road test is a sensible next step, with attention paid to rubbing, vibration, pulling, or unusual steering feel. Collector cars often sit for long periods, so it is wise to recheck pressure after the first drive and keep an eye on clearance around the fenders and inner wheel housings once the suspension has settled normally.
How should tires on a collector 1973 BMW 3.0 be maintained?
Tires on a collector 1973 BMW 3.0 should be inspected regularly for pressure loss, sidewall cracking, bulges, cuts, and uneven wear. Even a well-kept grand touring car can age its tires out before it wears them out, especially if it spends long periods parked indoors or under seasonal storage conditions.
Good maintenance also includes keeping the car away from prolonged sunlight, moisture, and ozone sources, and moving it occasionally to avoid flat spotting from long static storage. Before any longer drive, check inflation, tread condition, and general tire age. That routine matters whether the car is using the 175R14 fitment or the 195/70R14 setup.
