The 1970 BMW 2002 sits at the heart of the small sports sedan formula that helped define BMW's enthusiast reputation in the United States. Light weight, direct steering, and tidy proportions make tire choice especially important, because the wrong construction or profile can change both the car's stance and the way it feels on the road. This model uses either a 165R13 radial or a 600-13 bias-ply tire on a 13-inch rim. That gives owners a meaningful choice between traditional bias-ply presentation and radial options from Michelin and Dunlop, along with whitewall bias-ply alternatives. The right selection depends on whether the goal is road-friendly driving, a restoration-oriented look, or a careful balance of both.
Which Tire Size Is Right for The 1970 BMW 2002
The 1970 BMW 2002 uses two primary tire sizes, both on 13-inch rims: 165R13 in radial construction and 600-13 in bias-ply construction. Because the same covered sub-model uses both sizes, the real decision is not sub-model identification but whether the car is staying with a traditional bias-ply setup or moving toward the road manners and sizing convention of a radial.
165R13 is a Euro-metric radial size in which 165 identifies nominal section width in millimeters, R marks radial construction, and 13 is the rim diameter in inches. On a 1970 BMW 2002, it represents the radial side of the fitment picture and suits owners who want a period-appropriate European sizing format. Available choices include Michelin and Dunlop blackwall tires in series such as XAS-FF, XAS, and SP Sport Aquajet. This size is worth considering when maintaining a classic European look while keeping the car on a 13-inch radial setup.
600-13 is a numeric bias-ply size, with the leading number representing a nominal 6.00-inch section-width class and the final number indicating a 13-inch rim. On the 1970 BMW 2002, it is the bias-ply fitment choice for owners pursuing a more traditional tire construction and appearance. BFGoodrich offers this size in the Silvertown Classic Bias Ply series with both narrow whitewall and wide whitewall sidewall treatments. This size deserves a close look when the goal is a restoration-oriented presentation built around vintage construction and period-style sidewall character.
Fitment is straightforward across the covered 1970 BMW 2002 sub-models, with the same radial and bias-ply tire choices carried through the range. Checking the exact sub-model still helps confirm whether the car should stay with its current construction or be evaluated against the alternate tire type.

1970 BMW 2002 Base & A
The 1970 BMW 2002 Base & A uses the same 165R13 radial and 600-13 bias-ply fitment choices on 13-inch rims. That makes tire selection more about construction, appearance, and intended road use than about trim-specific size differences.
Bias-Ply to Radial Tire Conversion for the 1970 BMW 2002
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. Together, these options move from a traditional metric radial format to lower-profile P-metric alternatives. A recommended rim-width range of 4 to 5 inches is associated with these equivalents, so wheel width, overall dimensions, and clearance should be checked before changing from the original bias-ply size.
Modern Radial Equivalents

Important Considerations When Replacing Bias Ply With Radial
Compare overall diameter and section width carefully to ensure proper fit.
Verify recommended rim range (4-5 in) and load needs match your vehicle specifications.
Check fender clearance, steering clearance, and stance before installation.
Consider suspension condition and intended road use when choosing equivalents.
Important Fitment Notes
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 1970 BMW 2002 Tires for Sale
Available 1970 BMW 2002 tire choices span radial and bias-ply construction, with Michelin and Dunlop blackwall radials in 165R13 and BFGoodrich Silvertown Classic Bias Ply options in 600-13 with narrow or wide whitewall styling. Series, sidewall treatment, and rim-width compatibility are the main comparison points.
Common 1970 BMW 2002 tire questions usually center on choosing between 165R13 radial and 600-13 bias-ply fitment, understanding radial equivalents, and checking wheel, appearance, and road-use details before mounting a new set.
Tire Size & Fitment
What tire size fits a 1970 BMW 2002?
A 1970 BMW 2002 uses two primary tire sizes: 165R13 in radial construction and 600-13 in bias-ply construction. Both sizes are associated with 13-inch rims, so the main fitment question is not wheel diameter alone, but which construction type matches the car's current setup and the owner's goals.
That distinction matters because a 165R13 radial and a 600-13 bias-ply are not simply different labels for the same buying decision. One follows a metric radial sizing convention, while the other uses a vintage numeric bias-ply format. Before choosing, confirm the actual wheels on the car, the tire construction already in use, and whether the priority is restoration-style appearance or a radial-oriented driving setup.
What size rim does a 1970 BMW 2002 use?
The tire fitments for a 1970 BMW 2002 use a 13-inch rim diameter. That applies to both the 165R13 radial size and the 600-13 bias-ply size, so either primary tire option is built around the same rim diameter even though the construction and sizing systems differ.
Rim diameter is only the first checkpoint. Wheel width also matters, especially when comparing the available bias-ply and radial products, because the approved width ranges are not identical across those two sizes. A car with replacement wheels should have both diameter and width verified before a tire is selected, particularly if the goal is to move from bias-ply construction to a radial alternative.
Does the 1970 BMW 2002 Base & A use the same tire size?
Yes. The 1970 BMW 2002 Base & A uses the same fitment choices as the core model: 165R13 in radial form and 600-13 in bias-ply form. There is no separate tire-size split here that forces one covered sub-model into a different rim diameter or a different primary size family.
That keeps the decision focused on tire type rather than trim-level differences. An owner can concentrate on whether the car should stay with a traditional 600-13 bias-ply presentation or use a 165R13 radial setup. It is still smart to inspect the wheels actually installed on the car, since many vintage BMWs have seen wheel changes over the years.
Bias-Ply & Radial Options
Is 600-13 a bias-ply or radial tire for the 1970 BMW 2002?
For the 1970 BMW 2002, 600-13 is a bias-ply tire size. It uses a vintage numeric sizing format rather than a metric radial format, and it is offered in bias-ply construction with whitewall sidewall treatments in the available product selection for this application.
That makes 600-13 the traditional-construction choice for owners who want a more vintage presentation on a 13-inch wheel. A bias-ply setup can make sense for restoration-oriented use, but it should not be confused with the 165R13 radial fitment. Anyone changing constructions should confirm wheel width, clearance, and the overall direction of the build before making the switch.
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 75-series P-metric radial, and P175/70R13 as a 70-series P-metric radial. These are the radial alternatives associated with the original bias-ply size for a 1970 BMW 2002.
Each of those equivalents keeps the 13-inch rim diameter but uses a different radial sizing convention and profile family. The recommended rim-width range tied to these equivalents is 4 to 5 inches, which is an important checkpoint before conversion. A careful comparison of wheel width, mounted dimensions, and body or suspension clearance is the right next step rather than assuming interchangeability.
Should I use bias-ply or radial tires on a 1970 BMW 2002?
That depends on what matters most for the car. A 600-13 bias-ply tire keeps the vintage numeric sizing format and a more traditional visual character, while a 165R13 radial keeps the 13-inch rim diameter but follows a classic European radial format used on the same model year BMW 2002.
Owners focused on a restoration-oriented look often start with the bias-ply size, especially when sidewall appearance matters. Owners planning regular road use often look at the radial fitment or the radial equivalents tied to 600-13. The best choice comes from balancing appearance, wheel compatibility, and how the car will actually be driven rather than treating one construction as automatically correct.
Choosing the Right Tire
What should I consider when choosing a tire for a 1970 BMW 2002?
Start with the two primary fitment paths for the 1970 BMW 2002: 165R13 radial or 600-13 bias-ply. From there, the important factors are tire construction, 13-inch wheel compatibility, intended use, and whether the car is being kept closer to a traditional restoration-style presentation or a more road-oriented radial setup.
Product differences also matter once the correct size family is established. In this application, choices vary by brand, tire series, sidewall style, and approved rim-width range. A blackwall Michelin or Dunlop radial gives a different look than a BFGoodrich bias-ply whitewall, so the right answer usually comes from matching the tire's appearance and construction to the car's overall character.
What sidewall styles are available for 1970 BMW 2002 tires?
Sidewall choices for the 1970 BMW 2002 include blackwall in the 165R13 radial offerings and both narrow whitewall and wide whitewall in the 600-13 bias-ply offerings. That creates a clear visual split between the radial choices and the more traditional whitewall bias-ply presentation.
Sidewall style can change the look of the car as much as the tire construction itself. A blackwall radial suits a cleaner European sports sedan appearance, while a whitewall bias-ply leans more heavily into vintage visual character. The best match depends on how original-looking, understated, or personalized the car is intended to appear once the correct size and wheel setup are confirmed.
What brands offer tires for the 1970 BMW 2002?
Michelin, Dunlop, and BFGoodrich all offer tire choices for the 1970 BMW 2002 across its primary sizes. Michelin and Dunlop cover the 165R13 radial side with blackwall options, while BFGoodrich covers the 600-13 bias-ply side with whitewall tires in the Silvertown Classic Bias Ply series.
Brand choice should be considered alongside size, construction, and visual style rather than treated as the first decision. Michelin XAS-FF, Michelin XAS, and Dunlop SP Sport Aquajet keep the discussion in classic radial territory, while BFGoodrich bias-ply whitewalls point the car toward a more traditional presentation. Selecting the right tire starts with the intended setup, then narrows by brand and series.
Restoration & Appearance
Which tire should I choose for a period-style 1970 BMW 2002?
A period-style 1970 BMW 2002 can be approached in two different ways. The 600-13 bias-ply size emphasizes vintage construction and a traditional presentation, while 165R13 keeps the car in a classic European radial format that also suits the era and the character of the 2002.
The better choice depends on what kind of period impression matters most. A restoration-oriented build may lean toward the bias-ply path, especially if whitewall treatment is part of the visual plan, while a road-driven car may feel more at home on a 165R13 radial. When exact originality matters, vehicle-specific historical references and marque guidance are worth checking before finalizing the look.
How does tire construction affect the appearance of a restored 1970 BMW 2002?
Tire construction changes both the visual stance and the character of a restored 1970 BMW 2002. A 600-13 bias-ply brings a more vintage look, especially with narrow or wide whitewall styling, while a 165R13 radial presents the car with a cleaner blackwall European sports sedan appearance.
That visual difference matters because the BMW 2002 is a compact, proportion-sensitive car. The tire is highly visible, so sidewall treatment and sizing format can shift the overall impression from restoration-oriented to more driver-focused. Construction choice should be made alongside wheel finish, ride height, and the intended era of the build so the final look feels coherent rather than mixed.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1970 BMW 2002?
Yes. Modifications can change how a tire fits on a 1970 BMW 2002 even when the tire size itself is appropriate for the model. Aftermarket wheels, altered wheel width, suspension changes, lowering, or body modifications can all affect clearance at the fender, steering, or suspension points.
That is especially important when comparing 600-13 bias-ply fitment with 165R13 radial or radial-equivalent alternatives. A car that no longer has its original wheel setup should have wheel diameter and width checked first, then be inspected for turning and bump clearance. Vintage cars often carry decades of changes, so a quick visual confirmation is not enough when fitment is close.
What should I inspect before driving a 1970 BMW 2002 on new tires?
Before driving a 1970 BMW 2002 on new tires, inspect the wheels for correct diameter and general condition, then check that each tire is seated properly and inflated appropriately for the setup being used. It is also wise to look over steering and suspension components, since worn parts can affect how a fresh tire feels on the road.
A short, careful test drive should follow, with attention to pulling, rubbing, vibration, or unusual contact at full steering lock. Collector cars that sit for long periods deserve extra scrutiny because old shocks, bushings, or alignment issues often become more obvious once new tires are mounted. Catching those issues early helps protect both the tires and the driving experience.
How should tires on a collector 1970 BMW 2002 be maintained?
Tires on a collector 1970 BMW 2002 should be checked regularly for pressure, tread condition, cracking, bulges, cuts, and slow air loss, even if the car is driven only occasionally. Low-use cars often age their tires through time and storage conditions rather than through mileage alone, so visual inspection is just as important as tread depth.
Storage conditions matter too. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment helps preserve both radial and bias-ply tires. Moving the car periodically and checking it before each outing is a good habit, since a BMW 2002 that spends weeks in the garage can still develop pressure loss or age-related deterioration between drives.
