The 1971 BMW 1600 sits in an important moment for BMW’s compact sport sedan and coupe lineage, when tidy dimensions, light weight, and responsive road manners helped define the brand’s enthusiast reputation. For owners today, tire selection is closely tied to the exact sub-model, because the 1600 family used both bias-ply and radial fitments across 13-inch and 14-inch wheel applications. That means the decision is not just about size, but also about whether to stay with a period-style bias-ply presentation or choose one of the available radial options. Getting that choice right helps preserve the car’s character while keeping wheel size, appearance, and intended road use aligned.
Which Tire Size Is Right for The 1971 BMW 1600
The 1971 BMW 1600 uses six primary tire sizes, and the correct one depends on the exact sub-model as well as whether the car is set up for bias-ply or radial tires. Wheel diameter matters immediately here, since both 13-inch and 14-inch rim applications appear across the range, so the first step is confirming the sub-model and checking the actual wheels on the car before choosing a tire.
165R13 is a Euro-metric radial size in which 165 designates nominal section width in millimeters, R indicates radial construction, and 13 is the wheel diameter in inches. On the 1971 BMW 1600, this is a traditional metric radial fitment used on a 13-inch rim application. Available choices include blackwall tires from Michelin and Dunlop, with series such as Michelin XAS-FF, Michelin XAS, and Dunlop SP Sport Aquajet. This size suits an owner who wants a period European radial format and should be matched to the correct wheel setup before installation.
600-13 is a numeric bias-ply size where 6.00 refers to the tire’s nominal section width in inches and 13 identifies the rim diameter. For the 1971 BMW 1600, it represents a vintage-style bias-ply fitment on a 13-inch wheel rather than a modern radial specification. BFGoodrich options in this size are offered in the Silvertown Classic Bias Ply series with whitewall treatments including wide whitewall and narrow whitewall. This size is the right place to start when maintaining a traditional bias-ply look, while still confirming wheel width and overall vehicle setup.
165R14 is a Euro-metric radial size with a 165-millimeter nominal section width, radial construction, and a 14-inch rim diameter. On the 1971 BMW 1600, it is one of the radial fitments tied to a 14-inch wheel application, so it cannot be chosen solely by model year alone. Blackwall options are available from Pirelli, Michelin, and Vredestein in series including Cinturato CA67, Michelin XAS, and Sprint Classic. This size is appropriate for owners seeking a classic European radial presentation, provided the wheel diameter and sub-model match.
6.00-14 is a numeric bias-ply size, with the leading number expressing nominal width in inches and the final number showing a 14-inch rim diameter. For the 1971 BMW 1600, it serves as a period-style bias-ply fitment on certain 14-inch applications rather than a universal size across the model range. Its practical significance is preserving the earlier construction style associated with a traditional tire profile and appearance. This size makes sense when the goal is to stay with a bias-ply setup, but wheel diameter and the exact sub-model should be confirmed first.
155R14 is a Euro-metric radial size in which 155 indicates nominal section width in millimeters, R identifies radial construction, and 14 denotes the wheel diameter. On the 1971 BMW 1600, this narrower metric radial fitment belongs to a specific 14-inch application, so it should not be confused with the larger 165R14 radial used elsewhere in the range. Available blackwall choices include the Michelin X Radial series and the Firestone F560 Radial. This size is a useful fitment for owners who want a classic radial tire in the correct width category for that particular setup.
520-14 is a numeric bias-ply size where 5.20 represents nominal tire width in inches and 14 identifies the rim diameter. Within the 1971 BMW 1600 family, this is a narrower 14-inch bias-ply application tied to a specific sub-model rather than a broad all-model fitment. Product choice centers on Premium Sport offerings in the Premium Sport Lowrider series, all with narrow whitewall styling in different visual treatments. This size is most relevant when preserving a distinct period-style bias-ply appearance, and it should be chosen only after verifying the wheel and sub-model combination.
Tire fitment varies across the 1971 BMW 1600 sub-model range, so identifying the exact version of the car is the first step before selecting a tire. The main differences involve both wheel diameter and whether the car uses a bias-ply or radial size.

1971 BMW 1600 /2
The 1971 BMW 1600 /2 uses a 13-inch tire fitment, with both a radial and a bias-ply option associated with this sub-model. That gives the owner a clear choice between a more traditional bias-ply presentation and a period European radial format, as long as the wheel size and actual wheel width are confirmed.
The 1971 BMW 1600 /4 uses 14-inch tire fitments and has both radial and bias-ply sizing associated with it. Tire selection here depends on retaining the intended construction type and confirming that the car still carries the correct 14-inch wheels rather than a later or modified setup.
The 1971 BMW 1600 GT uses a distinct 14-inch fitment with both radial and bias-ply sizes that differ from the /4. That makes sub-model identification especially important, since the right choice is tied not only to construction style but also to the narrower sizing used on this version.
Bias-Ply to Radial Tire Conversion for the 1971 BMW 1600
For the original 600-13 tire size, three radial-equivalent options are available. 165R13 is the 80-series metric radial equivalent, P165/75R13 is the P-metric 75-series radial equivalent, and P175/70R13 is the P-metric 70-series radial equivalent. These choices give a progression from a traditional metric radial format to two P-metric alternatives with different profile families. A recommended rim-width range of 4 to 5 inches applies, and any conversion should still be checked against the wheel, overall vehicle setup, and clearance around the tire.

Common 1971 BMW 1600 tire questions center on sub-model fitment, 13-inch versus 14-inch wheel applications, bias-ply versus radial choices, and how to match tire appearance to a restoration-minded car. The answers below focus on the exact sizes used across the 1600 range and what to verify before road use.
Tire Size & Fitment
What tire size fits a 1971 BMW 1600?
A 1971 BMW 1600 can use 165R13, 600-13, 165R14, 6.00-14, 155R14, or 520-14, depending on the exact sub-model and whether the car is using radial or bias-ply tires. The /2 uses 13-inch sizes, while the /4 and 1600 GT use 14-inch sizes with different radial and bias-ply combinations.
The practical step is to identify the sub-model first and then confirm the wheel diameter actually on the car, since many vintage BMWs may have been changed over the years. Choosing by model year alone can lead to the wrong rim diameter or the wrong construction type, especially when both bias-ply and radial fitments are associated with the 1971 1600 family.
What size rim does a 1971 BMW 1600 use?
The 1971 BMW 1600 appears with both 13-inch and 14-inch rim applications. The 1600 /2 uses 13-inch tire sizes, while the 1600 /4 and 1600 GT use 14-inch tire sizes, so rim diameter is not the same across all covered versions of the car.
That makes wheel confirmation a necessary part of tire selection. A 13-inch tire and a 14-inch tire are not interchangeable, even if the rest of the car appears similar. It is wise to check the stamping on the wheel or verify the size already mounted before selecting a replacement, especially on a collector car that may have seen wheel or suspension changes over time.
Why does the 1971 BMW 1600 have more than one tire size?
More than one tire size applies to the 1971 BMW 1600 because the covered sub-models do not all share the same wheel diameter or the same construction format. The range includes both 13-inch and 14-inch applications, and several sub-models have a radial size and a separate bias-ply size associated with them.
That means the first decision is not which brand to choose, but which exact fitment belongs on the specific car. Once the sub-model and wheel diameter are confirmed, the owner can decide whether the goal is a period-style bias-ply appearance or a radial setup. That approach keeps the selection grounded in the car’s actual configuration instead of a generic 1600 label.
Bias-Ply & Radial Options
Is 600-13 a bias-ply or radial tire for the 1971 BMW 1600?
On the 1971 BMW 1600, 600-13 is a numeric bias-ply tire size. Its radial counterpart in the same general 13-inch application is 165R13, but 600-13 itself is the bias-ply fitment and uses a different construction from the metric radial option.
That distinction matters because the construction choice affects both appearance and wheel compatibility considerations. A buyer looking at 600-13 should think in terms of maintaining a traditional bias-ply setup, while anyone considering a switch to a radial should compare the wheel width, overall tire envelope, and clearance before assuming the change suits the car’s present configuration.
What radial tire sizes are equivalent to 600-13?
Radial equivalents for 600-13 include 165R13 as an 80-series metric radial, P165/75R13 as a P-metric 75-series radial, and P175/70R13 as a P-metric 70-series radial. Those options give the 1971 BMW 1600 owner several radial formats to compare within the same general 13-inch application.
The recommended rim-width range for these equivalents is 4 to 5 inches, which provides an important checkpoint before making a conversion. Metric and P-metric sizes do not express dimensions in the same way as a numeric bias-ply tire, so wheel width, overall fit within the wheelwell, and steering clearance should all be reviewed before selecting one of these radial alternatives.
What should I check before converting my 1971 BMW 1600 from bias-ply to radial tires?
Start by confirming the exact sub-model, the wheel diameter, and the original bias-ply size on the car, because the 1971 BMW 1600 uses more than one rim size and more than one bias-ply fitment. For a 600-13 application, the available radial equivalents include 165R13, P165/75R13, and P175/70R13.
The next checks are wheel width, tire-to-fender clearance, steering clearance, and the overall condition of the suspension and alignment setup. A collector BMW that has aftermarket wheels or ride-height changes may respond differently than a stock car. Keeping those checks in view helps the owner evaluate a radial alternative as a fitment decision, not simply as a construction swap.
Choosing the Right Tire
What should I consider when choosing a 1971 BMW 1600 tire?
The most important factors are the exact sub-model, the correct tire size, the wheel diameter, and whether the car is meant to stay with a bias-ply setup or use a radial fitment. The 1971 BMW 1600 spans six sizes across 13-inch and 14-inch applications, so the right choice begins with confirming the actual wheel and fitment already on the car.
After that, the decision usually narrows to appearance and use. A radial may suit an owner seeking a classic European road-tire presentation, while a bias-ply may better match a traditional restoration-minded look. It also helps to compare rim-width specifications, sidewall styling, and any stated load figures so the selected tire aligns with both the wheel and the intended use of the vehicle.
What sidewall styles are available for 1971 BMW 1600 tires?
Sidewall style depends on the size and construction being considered. Radial options for the 1971 BMW 1600 are offered as blackwall tires, while bias-ply choices include whitewall treatments such as wide whitewall and narrow whitewall, depending on the specific size and product line.
That gives the owner a meaningful appearance decision in addition to the fitment decision. A blackwall radial keeps the look understated and European in character, while a whitewall bias-ply creates a more stylized vintage presentation. The key is to choose the sidewall treatment only after confirming the correct tire size for the sub-model, rather than selecting by appearance first.
What brands offer tires for the 1971 BMW 1600?
Brands available across 1971 BMW 1600 fitments include Michelin, Dunlop, Pirelli, Vredestein, Firestone, BFGoodrich, and Premium Sport. Which brands apply depends on the tire size, because the radial and bias-ply options are split across different wheel diameters and different sub-model applications.
Brand choice should be treated as one part of the selection process rather than the starting point. It makes more sense to confirm the exact size first, then compare the brands offered within that fitment by construction, tire series, sidewall treatment, rim-width compatibility, and any stated load details. That keeps the decision centered on fitment and intended appearance instead of on brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1971 BMW 1600?
A period-style 1971 BMW 1600 tire choice usually starts with the primary size assigned to the exact sub-model and then with the construction style that matches the car’s intended presentation. Bias-ply sizes such as 600-13, 6.00-14, or 520-14 create the most traditional look, while metric radials like 165R13, 165R14, and 155R14 retain a classic European tire format.
The right answer depends on whether the restoration goal is a more traditional visual stance or a radial-equipped road car with vintage character. Appearance details such as blackwall or whitewall treatment also matter, but they should be secondary to getting the correct size and wheel diameter. When exact originality matters, marque references and period documentation are worth consulting before choosing a final combination.
How does tire construction affect the appearance of a restored 1971 BMW 1600?
Tire construction changes the visual character of a restored 1971 BMW 1600 even when the rim diameter is correct. A bias-ply tire tends to support a more traditional vintage presentation, especially when paired with whitewall styling, while a Euro-metric radial gives the car a more classic road-going look associated with later-period radial fitments.
That visual difference is one reason construction should be chosen deliberately rather than as an afterthought. A buyer restoring the car for display may prioritize the period-style presence of the bias-ply sizes, while an owner building a driver may lean toward one of the radial fitments available for the proper sub-model. Matching construction to the restoration goal usually produces the most coherent result.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1971 BMW 1600?
Yes, modifications can affect tire fitment on a 1971 BMW 1600. The car already spans both 13-inch and 14-inch wheel applications from the outset, so aftermarket wheels, altered wheel widths, suspension changes, or body modifications can make the correct original tire size only part of the fitment picture.
A modified car should be checked for actual wheel diameter, wheel width, and tire clearance at the fender and steering components before a replacement is chosen. Even when the selected size matches a known 1600 fitment, a changed setup can alter what works comfortably on the vehicle. That is especially important when moving between bias-ply and radial constructions.
What should I inspect before driving a 1971 BMW 1600 on new tires?
Before driving a 1971 BMW 1600 on new tires, inspect the wheels for the correct diameter and condition, verify that the tires are properly mounted and inflated, and check for adequate clearance through steering travel and suspension movement. It is also wise to confirm that lug hardware, wheel seating surfaces, and valve stems are in good shape.
A short initial road test can reveal rubbing, vibration, or pull that may not be obvious while the car is stationary. Collector cars often spend long periods parked, so alignment condition, brake drag, and suspension wear deserve attention as well. Catching those issues early helps the new tires work as intended and protects the overall drivability of the car.
How should tires on a collector 1971 BMW 1600 be maintained?
Tires on a collector 1971 BMW 1600 should be kept at appropriate inflation, inspected regularly for cracking, cuts, bulges, uneven wear, and slow air loss, and protected from long periods of sun, moisture, and ozone exposure. Cars that are driven infrequently still need routine tire checks because age and storage conditions can affect rubber even when tread wear is minimal.
It also helps to move the car periodically or store it in a way that reduces prolonged flat-spotting. Before a longer drive, look closely at both sidewalls and confirm that the tires still match the wheel and suspension setup currently on the car. Consistent maintenance matters just as much on vintage BMWs as choosing the correct size in the first place.
