The 1970 BMW 2000 sits in the era when BMW’s Neue Klasse sedans helped define the brand’s modern sporting identity, blending compact European proportions with crisp road manners and understated luxury. For today’s owner, tire choice plays a big role in preserving that character. This model uses 14-inch fitments in both radial and bias-ply forms, with 165R14 or 6.45-14 on Base & A cars and 175R14 or 695-14 on Tilux, C, CA & CS versions. Available options range from traditional blackwall metric radials to bias-ply tires with whitewall, redline, and raised white letter styling. The right choice depends on the exact sub-model, the wheels on the car, and whether the goal is restoration-oriented appearance or road-driving practicality.
Which Tire Size Is Right for The 1970 BMW 2000
Four primary tire sizes apply to the 1970 BMW 2000, and the correct one depends on the exact sub-model rather than a change in rim diameter, since all of them use 14-inch wheels. The first step is confirming whether the car is a Base & A or a Tilux, C, CA & CS, then deciding whether a period-style bias-ply tire or a radial fitment better suits the car’s intended use and presentation.
165R14 is a Euro-metric radial size in which 165 refers to nominal section width in millimeters, R identifies radial construction, and 14 is the wheel diameter in inches. On the 1970 BMW 2000, this is one of the radial fitments used on Base & A models and it reflects the European sizing language common to the period. Available choices include Pirelli, Michelin, and Vredestein, all in blackwall form across series such as Cinturato CA67, XAS, and Sprint Classic. It is a strong option for an owner who wants a radial tire in the proper 14-inch format while keeping a traditional European look.
6.45-14 is a numeric bias-ply size, with 6.45 indicating nominal section width in inches and 14 identifying the wheel diameter. For the 1970 BMW 2000, this is the bias-ply companion fitment for Base & A cars and suits buyers who want to stay closer to an earlier tire construction style. Bias-ply sizing like this is less familiar to modern drivers, so the code matters most as a fitment language tied to the car’s original-era tire convention. It is the size to evaluate when appearance, construction type, and period-style presentation are more important than moving to a radial.
175R14 is a Euro-metric radial size where 175 is the nominal section width in millimeters, R denotes radial construction, and 14 is the rim diameter in inches. On the 1970 BMW 2000, this radial size applies to Tilux, C, CA & CS models rather than the Base & A versions. Michelin and Vredestein offer this size in blackwall form, with series including XAS, Sprint Plus, and Sprint Classic, giving buyers some variation in period-style European radial presentation. It is the right size to examine when the car falls into the higher-fitment sub-model group and remains on the proper 14-inch wheel.
695-14 is a numeric bias-ply size in which 695 represents nominal section width in the older bias-ply sizing system and 14 identifies the wheel diameter. For the 1970 BMW 2000, this size belongs to Tilux, C, CA & CS models as the bias-ply alternative to 175R14. Product choices are broad here, with BFGoodrich, US Royal, and Goodyear offerings in blackwall, narrow whitewall, dual redline, raised white letter, and Blue Streak presentations across several vintage tire series. It is the size to consider when sub-model fitment points to the larger BMW 2000 bias-ply setup and appearance choice matters as much as construction.
Sub-model identification matters on the 1970 BMW 2000 because the covered versions do not all share the same tire sizing. Every configuration uses a 14-inch wheel, but the correct radial or bias-ply size changes between the Base & A group and the Tilux, C, CA & CS group.

1970 BMW 2000 Base & A
The 1970 BMW 2000 Base & A uses the smaller of the two fitment groups, with a choice between radial and bias-ply sizing on a 14-inch rim. Tire selection here centers on whether the car is being kept in a more traditional presentation or moved toward a period-style radial setup.
The 1970 BMW 2000 Tilux, C, CA & CS uses the larger 14-inch fitment group, again with both radial and bias-ply paths available. That makes it important to confirm the exact sub-model first, then compare radial alternatives or bias-ply sidewall treatments within the correct size family.
Bias-Ply to Radial Tire Conversion for the 1970 BMW 2000
For the original 695-14 size, three radial-equivalent options are available. 175R14 is the 80-series metric radial equivalent, P185/75R14 is the P-metric 75-series radial equivalent, and P195/70R14 is the P-metric 70-series radial equivalent. These choices give a progression from a traditional Euro-metric radial format to later P-metric alternatives with different profile conventions. A recommended rim-width range of 4 to 6 inches applies, and any change should still be checked against the wheel, overall dimensions, and vehicle clearance.

These FAQs focus on the exact tire sizes used on the 1970 BMW 2000, how fitment changes by sub-model, and how to sort through bias-ply, radial, sidewall, and maintenance decisions before the car goes back on the road.
Tire Size & Fitment
What tire size fits a 1970 BMW 2000?
A 1970 BMW 2000 can use 165R14, 6.45-14, 175R14, or 695-14, depending on the sub-model and whether the car is running a radial or bias-ply tire. Base & A models use 165R14 or 6.45-14, while Tilux, C, CA & CS models use 175R14 or 695-14.
The practical step is identifying the exact version of the car before choosing a tire. All four sizes fit 14-inch wheels, but that does not make them interchangeable across every BMW 2000 configuration. Tire construction, wheel width, and the car’s current setup should all be confirmed before moving between the smaller and larger fitment groups.
What size rim does a 1970 BMW 2000 use?
The 1970 BMW 2000 uses a 14-inch rim across its supported tire sizes. That applies to both the radial sizes, 165R14 and 175R14, and the bias-ply sizes, 6.45-14 and 695-14.
Rim diameter is only the first part of the fitment picture. A 14-inch wheel can still vary in width, and that matters when comparing different tire constructions or considering a radial equivalent for a bias-ply size. It is smart to verify the actual wheel on the car, especially if the BMW has been restored, modified, or fitted with replacement wheels over the years.
Do all 1970 BMW 2000 sub-models use the same tire size?
No. The 1970 BMW 2000 uses two distinct fitment groups by sub-model. Base & A models use 165R14 or 6.45-14, while Tilux, C, CA & CS models use 175R14 or 695-14.
That difference matters because selecting by year and model alone can still leave you in the wrong size family. Once the sub-model is confirmed, the next decision is whether to stay with the original-era construction style or consider the radial option within that same fitment group. Keeping the tire matched to the car’s wheel and intended appearance helps avoid a mismatch in stance or clearance.
Bias-Ply & Radial Options
What radial tire sizes are equivalent to 695-14?
Radial equivalents for 695-14 include 175R14 as an 80-series metric radial, P185/75R14 as a P-metric 75-series radial, and P195/70R14 as a P-metric 70-series radial. These are alternative sizing formats tied to the 695-14 bias-ply fitment, not additional primary sizes for every 1970 BMW 2000 sub-model.
Each of those sizes should be evaluated against the wheel and the car’s actual setup before conversion. The recommended rim-width range for the 695-14 equivalents is 4 to 6 inches, and clearance should still be checked at the fender, suspension, and steering positions. That is especially important on a collector BMW that may no longer be wearing its original wheels.
Should I use bias-ply or radial tires on a 1970 BMW 2000?
Either construction can be appropriate on a 1970 BMW 2000, depending on the sub-model and the goal for the car. Radial choices include 165R14 and 175R14, while bias-ply choices include 6.45-14 and 695-14. The correct comparison starts with the exact sub-model so the tire stays within the proper fitment group.
The decision usually comes down to appearance, driving expectations, and wheel setup. A restoration-oriented car may favor the traditional look of a bias-ply tire, while a road-driven car may lead an owner toward the available radial fitment or an approved radial equivalent where offered. Construction changes should always be checked against wheel width, clearance, and overall vehicle condition.
What should I check before converting my 1970 BMW 2000 from bias-ply to radial tires?
Start by confirming the BMW 2000 sub-model and the original bias-ply size on the car. For the 695-14 fitment, radial alternatives include 175R14, P185/75R14, and P195/70R14. The wheel must still be appropriate for the radial size being considered, and the published equivalent rim-width range for 695-14 alternatives is 4 to 6 inches.
Beyond wheel size, inspect steering and fender clearance, suspension condition, and the car’s current ride height before making the change. A tire that shares the same rim diameter does not automatically behave the same in every setup. On an older sedan, it also helps to make sure alignment, bushings, and general chassis condition are sorted before putting the car back into regular road use.
Choosing the Right Tire
What should I consider when choosing a 1970 BMW 2000 tire?
Begin with the exact sub-model, because the 1970 BMW 2000 does not use one universal tire size. Base & A cars use the 165R14 or 6.45-14 fitment group, while Tilux, C, CA & CS cars use 175R14 or 695-14. After that, the main decision is radial versus bias-ply construction within the correct size family.
Once size and construction are settled, compare the presentation and specifications that matter to your use. Blackwall radials suit a traditional European look, while 695-14 bias-ply options offer much more sidewall variety. Wheel width, load figures where shown, and whether the BMW is being restored, displayed, or driven more regularly all help narrow the right choice.
What sidewall styles are available for 1970 BMW 2000 tires?
Sidewall choice depends heavily on tire size and construction. The radial 165R14 and 175R14 products are offered in blackwall form, while the 695-14 bias-ply size is available in blackwall, narrow whitewall, dual redline, RWL, and raised-white-letter-blue-streak styles.
That means the appearance decision is much broader if your BMW 2000 uses the 695-14 fitment group. A buyer aiming for a restrained European look may stay with blackwall, while a more individualized vintage presentation may lean toward whitewall or redline styling. Sidewall appearance should always come after confirming the correct size for the specific sub-model.
What brands offer tires for the 1970 BMW 2000?
The 1970 BMW 2000 is served by several established vintage-tire brands, depending on size. Radial options include Pirelli, Michelin, and Vredestein, while bias-ply choices in 695-14 include BFGoodrich, US Royal, and Goodyear.
Brand is only one part of the decision, since the available offerings also differ by series, sidewall treatment, and in some cases rim-width specification or load information. It helps to compare brands within the correct tire size rather than across unrelated fitments. That approach keeps the focus on what actually suits the BMW’s sub-model, wheels, and intended presentation.
Restoration & Appearance
Which tire should I choose for a period-style 1970 BMW 2000?
A period-style choice starts with using the correct fitment group for the specific 1970 BMW 2000 sub-model. Base & A cars point toward 165R14 or 6.45-14, while Tilux, C, CA & CS cars use 175R14 or 695-14. From there, bias-ply construction generally gives the more traditional vintage presentation, while Euro-metric radials preserve a classic European look.
The best visual match depends on how strictly the car is being restored and what appearance the owner wants to preserve. Blackwall radials can look very appropriate on a sporting German sedan, while a bias-ply tire may better suit a restoration-minded build. For exact originality beyond size and general construction style, marque references and period photography remain valuable guides.
How does tire construction affect the appearance of a restored 1970 BMW 2000?
Tire construction changes the visual character of a restored 1970 BMW 2000 even when the wheel diameter stays at 14 inches. Bias-ply sizes such as 6.45-14 and 695-14 tend to support a more traditional vintage presentation, while radial sizes like 165R14 and 175R14 give the car a more familiar European roadgoing look.
The effect becomes even more noticeable when sidewall treatments enter the picture. Blackwall radials keep the appearance understated, whereas the 695-14 bias-ply range opens the door to whitewall, dual redline, or raised white letter styling. Matching the construction to the car’s restoration theme usually creates a more coherent result than choosing by tread or brand name alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1970 BMW 2000?
Yes. A 1970 BMW 2000 may have the correct 14-inch rim diameter and still run into fitment issues if the car has aftermarket wheels, suspension changes, or altered ride height. Those changes can affect whether the intended 165R14, 6.45-14, 175R14, or 695-14 fitment still works as expected on the vehicle.
Wheel width and offset are especially important when moving between bias-ply and radial constructions or considering an equivalent radial size for 695-14. Clearance should be checked at full steering lock and through normal suspension movement. A careful inspection matters even more on older cars because previous repairs or bodywork can leave the wheel opening slightly different from stock.
What should I inspect before driving a 1970 BMW 2000 on new tires?
Before putting a 1970 BMW 2000 back on the road, inspect the wheels, valve stems, and the overall condition of the suspension and steering. Make sure the selected tire size matches the car’s sub-model and that the 14-inch wheels are suitable for the chosen construction, whether radial or bias-ply.
After installation, look for any sign of rubbing, uneven clearance, or air loss before taking the car on a longer drive. It also helps to confirm that the tires are inflated properly for their intended use and that the alignment is in good order. Older collector cars often reveal issues only after they begin moving again under load.
How should 1970 BMW 2000 tires be maintained on a collector car?
Collector-car tire care for a 1970 BMW 2000 starts with regular visual inspection, even if the car is driven only occasionally. Check for sidewall cracking, cuts, bulges, uneven wear, and pressure loss, whether the car wears radial 165R14 or 175R14 tires or bias-ply 6.45-14 or 695-14 tires.
Storage conditions matter just as much as mileage on an older BMW. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps protect the tires between drives. A short inspection before each outing is worthwhile, since low-use collector vehicles can develop age-related tire issues long before the tread appears worn out.
