1965 BMW 3200 Tires

The 1965 BMW 3200 uses two primary bias-ply tire sizes: 6.50-15 and 670-15. Both are vintage numeric sizes designed for 15-inch wheels, and the covered 3200 S & SC sub-model is associated with those same two sizes rather than a different rim diameter or a separate radial primary fitment.

The practical step is to confirm which size is already on the car and make sure the wheel setup matches before choosing a replacement. Since both sizes use a 15-inch rim, the decision usually comes down to the existing wheel-and-tire combination, the appearance you want, and whether you plan to stay with a traditional bias-ply tire or evaluate a radial equivalent tied to 670-15.

The primary tire fitments for the 1965 BMW 3200 are built around a 15-inch rim diameter. That applies to both 6.50-15 and 670-15, so the core wheel-diameter question is straightforward even though two vintage numeric tire sizes are associated with the car.

Rim diameter is only part of the picture, especially on a collector car that may have seen wheel changes over the years. It is worth measuring the actual wheel and checking the present tire markings before buying replacements. If you are comparing a 670-15 bias-ply tire with a radial equivalent, wheel width becomes especially important along with clearance at the fender, steering, and suspension.

On a 1965 BMW 3200, 670-15 is a numeric bias-ply tire size. The 670 represents a nominal section width of about 6.70 inches, and the 15 refers to the rim diameter in inches. It is a traditional sizing system used well before modern metric radial designations became standard.

Understanding that format helps when comparing period-style replacements with modern alternatives. A 670-15 bias-ply tire keeps the vintage size language and traditional construction, while radial equivalents for that size are identified in metric, P-metric, or bias-look radial form. The buyer should use the size marking as a starting point, then confirm the wheel, the current tire setup, and the desired appearance before changing construction.

For the 1965 BMW 3200, 670-15 is a primary bias-ply tire size. The available products in that size are bias-ply offerings, and the car’s main fitment story remains rooted in traditional 15-inch bias-ply construction rather than a primary radial specification.

That matters because a buyer choosing 670-15 is often deciding whether to preserve the original-style driving feel and appearance or to consider one of the radial equivalents offered for that size. Keeping the bias-ply fitment maintains the vintage sizing convention, while any shift to a radial alternative should include a careful check of wheel width, tire dimensions, and body or steering clearance on the specific car.

Radial equivalents for 670-15 include 195R15, P205/75R15, P215/70R15, and 670R15. Those options cover an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial equivalent that keeps a more traditional visual style than a modern-looking radial profile.

Each option should be treated as an alternative, not an automatic replacement. A recommended rim-width range of 5 to 7 inches is associated with these equivalents, and the actual wheel on the car should be measured before conversion. Clearance at the fenders and steering should also be reviewed, especially on an older BMW where wheel changes, suspension wear, or prior restoration work may affect the final fit.

Start by confirming which primary size the car is using now, because the radial equivalents are tied to 670-15. The wheel diameter should remain 15 inches, and wheel width matters as well, with the radial-equivalent group carrying a recommended rim-width range of 5 to 7 inches.

Beyond wheel dimensions, compare the car’s present tire-to-body and tire-to-suspension clearance before making the change. A collector car can have replacement wheels, altered ride height, or worn suspension parts that affect radial fitment differently than a bias-ply tire. It is also wise to consider whether the goal is road use, preservation of traditional appearance, or a compromise such as a bias-look radial.

A 670-15 tire choice for a 1965 BMW 3200 starts with confirming that 670-15 is the size currently appropriate for the car’s wheel setup. Once size is settled, the main variables are construction style, sidewall appearance, tire series, brand, and the rim-width specifications attached to the individual tire.

Available 670-15 products cover blackwall, narrow whitewall, and wide whitewall designs across several classic tire lines. That gives the buyer room to match the car’s presentation, whether the goal is understated touring style or a stronger restoration-oriented visual statement. Comparing rim-width specs, load figures where stated, and the intended use of the car will usually narrow the field more effectively than choosing by brand alone.

In 670-15, the 1965 BMW 3200 has access to blackwall, narrow whitewall, and wide whitewall tire styles. That range gives the car very different visual personalities, from a restrained European touring look with blackwalls to a more formal and period-flavored presentation with one of the whitewall options.

The best choice depends on how the car is being finished and how authentic-looking the overall presentation needs to feel. A whitewall can change the character of the car as much as the wheel cover or trim selection, so it is worth viewing the tire as part of the restoration theme, not just a wear item. Keeping the correct size and wheel compatibility comes first, then sidewall style becomes the appearance decision.

The 670-15 fitment for the 1965 BMW 3200 is available from Firestone, US Royal, Coker Classic, Universal Vintage Tire, BFGoodrich, Excelsior, Avon, Goodyear, and STA. Those brands appear across several classic bias-ply tire lines, giving the buyer a broad mix of presentation styles and vintage tire personalities within the same basic fitment.

Brand should be considered alongside the actual tire series, sidewall treatment, and wheel-width compatibility rather than treated as the only decision point. Some choices lean toward simple blackwall presentation, while others emphasize narrow or wide whitewalls in a more restoration-oriented direction. Looking at the tire as a combination of size, construction, series, and appearance usually leads to a more satisfying match for the car.

For a period-style 1965 BMW 3200, the starting point is one of the car’s primary 15-inch bias-ply sizes, either 6.50-15 or 670-15, depending on the wheel and tire setup already on the car. Staying with bias-ply construction preserves the vintage sizing language and traditional sidewall character that suits a restoration-oriented presentation.

From there, the decision becomes more visual and contextual than mechanical alone. A blackwall creates a more understated look, while narrow or wide whitewalls can push the car toward a more formal mid-century appearance. If exact originality is important, compare the chosen size and sidewall style against marque references, historic photos, or other vehicle-specific documentation before finalizing the tire.

Tire construction changes the overall look of a restored 1965 BMW 3200 more than many buyers expect. A bias-ply tire maintains the traditional stance and visual language associated with vintage numeric sizing, while a radial alternative can subtly shift how the sidewall and tread presentation look on the car, even when chosen as an equivalent to 670-15.

That difference is why many restorers decide on appearance first and construction second. A standard radial may suit a road-focused car, while a bias-look radial can be useful for someone trying to retain a more traditional visual impression. The final choice should reflect how the BMW will be used and how closely the finished car is meant to follow a period-style presentation.

Yes, modifications can affect tire fitment on a 1965 BMW 3200 even when the tire size itself is correct on paper. Aftermarket wheels, changes in wheel width, altered suspension height, brake conversions, or bodywork differences can all change how a 6.50-15, 670-15, or a radial equivalent sits within the available space.

That is especially important on a collector car that may have been restored in stages over decades. Before replacing tires, inspect the actual wheels on the car and check clearance at full steering lock and normal suspension travel. A tire that matches the nominal size still needs the right wheel dimensions and enough room at the fender and suspension to operate without rubbing.

Before driving a 1965 BMW 3200 on new tires, inspect the wheels for correct diameter and condition, confirm proper inflation, and make sure the tires have adequate clearance at the fenders, steering, and suspension. It is also wise to look over the valve stems, wheel fasteners, and the general condition of the suspension and steering components.

A fresh set of tires can reveal problems that older tires were masking, especially on a lightly used collector car. Check for uneven ride height, worn bushings, loose steering feel, or signs of contact after the first few miles. A short local test drive followed by another visual inspection is a smart way to confirm that the BMW is ready for regular road use.

670-15 tires on a collector 1965 BMW 3200 should be maintained with regular pressure checks, visual inspections, and careful storage habits. Look for sidewall cracking, cuts, bulges, uneven tread wear, and slow air loss, since collector cars often accumulate age-related tire issues long before they accumulate significant mileage.

Storage conditions matter almost as much as mileage on a low-use vintage BMW. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps protect the rubber over time. Even when the tread still looks good, tires deserve routine inspection before each drive and a closer review before any longer trip, especially if the car has been parked for extended periods.
