The 1965 BMW 700 belongs to the small-displacement, rear-engined era that helped establish BMW’s postwar identity before the brand moved into its better-known sports sedans and coupes. Compact, light, and distinctive, the 700 appeals to owners who care as much about proper proportion and period character as simple drivability. Tire fitment on the 1965 BMW 700 centers on 12-inch bias-ply sizes, with 5.60-12, 520-12, and 5.50-12 appearing across the model range. That makes the real decision less about modern upsizing and more about matching the correct size to the exact sub-model, then choosing the right appearance and construction approach for restoration goals and road use.
Which Tire Size Is Right for The 1965 BMW 700
The 1965 BMW 700 uses three primary tire sizes, and the correct choice depends on the exact sub-model. All three are bias-ply tires for 12-inch rims, so the key first step is confirming whether the car is an LS Coupe or a Sport & Cabrio, then matching that setup to the tire size and appearance you want to preserve.
The 5.60-12 size uses a vintage numeric bias-ply format in which the first number indicates the nominal section width in inches and the final number identifies the 12-inch rim diameter. On a 1965 BMW 700, this size suits owners staying with a traditional bias-ply construction and period-style overall presentation. Its role in the model range makes it important to verify the exact sub-model before ordering. For restoration-minded buyers, 5.60-12 is a size to evaluate when maintaining the car’s original small-car proportions matters as much as simple drivability.
The 520-12 designation is a vintage numeric bias-ply size, with 5.20 representing the nominal section width and 12 indicating the rim diameter. This is a traditional 12-inch bias-ply fitment for certain 1965 BMW 700 applications, and it is also the size with the clearest product and radial-equivalent choices. Available options include BFGoodrich products in the Silvertown Classic Bias Ply series with either blackwall or wide whitewall styling. It is a useful size for buyers balancing correct vintage sizing with the option to compare a modern radial equivalent on an appropriate wheel.
The 5.50-12 size follows the same vintage numeric bias-ply system, where the leading number refers to approximate nominal section width and the last number refers to the 12-inch wheel diameter. For the 1965 BMW 700, it is a sub-model-specific fitment rather than a universal size across the range. That makes wheel and model confirmation especially important before moving ahead with a replacement. Buyers focused on maintaining the compact stance and period tire profile of the correct Sport & Cabrio setup should consider this size carefully instead of substituting by appearance alone.
Sub-model fitment on the 1965 BMW 700 is not uniform, even though every application uses a 12-inch bias-ply tire. Checking the exact sub-model matters because the LS Coupe and the Sport & Cabrio do not rely on the same combination of primary tire sizes.

1965 BMW 700 LS Coupe
The 1965 BMW 700 LS Coupe uses 5.60-12 and 520-12 bias-ply tire sizes on 12-inch rims. That means the selection process starts with confirming which of those two period-size fitments matches the car, then deciding whether to stay with a traditional bias-ply tire or evaluate the available radial equivalent tied to 520-12.
The 1965 BMW 700 Sport & Cabrio uses 5.50-12 and 5.60-12 bias-ply tire sizes on 12-inch rims. For this sub-model, the main priority is confirming which of those two small-diameter vintage sizes belongs on the car before comparing appearance, construction, and any restoration-oriented tire choice.
Bias-Ply to Radial Tire Conversion for the 1965 BMW 700
For the original 520-12 tire size, two radial-equivalent options are available. 125R12 is the 80-series metric radial equivalent, while P125/75R12 is the P-metric 75-series radial equivalent. These alternatives give the 1965 BMW 700 two modern radial sizing formats to consider without changing rim diameter. A recommended rim-width range of 4 to 5 inches applies to these equivalents, so wheel width, overall dimensions, and clearance should be checked before moving from the original bias-ply size.
Modern Radial Equivalents
125R12
Equivalent 80-series Metric Radial (520-12)
P125/75R12

Tire Size & Fitment
What tire size fits a 1965 BMW 700?
The 1965 BMW 700 uses three primary bias-ply tire sizes across the model range: 5.60-12, 520-12, and 5.50-12. All of them are built for 12-inch rims, but they do not apply uniformly to every version of the car. The LS Coupe uses 5.60-12 and 520-12, while the Sport & Cabrio uses 5.50-12 and 5.60-12.
That means the first step is identifying the exact sub-model and then confirming the wheel setup actually on the car today. Many collector vehicles have changed hands, and small vintage cars are sometimes fitted with different wheels over time. Matching the correct tire size to the sub-model helps preserve proper proportions and avoids making a choice based only on what happens to be mounted now.
What size rim does a 1965 BMW 700 use?
The tire fitments used on the 1965 BMW 700 are built around a 12-inch rim diameter. That applies to 5.60-12, 520-12, and 5.50-12, so the wheel diameter remains consistent even though the tire sizes vary by application. For buyers used to modern sizing, the final number in each of these vintage numeric sizes is the wheel diameter in inches.
Rim diameter is only one part of the fitment picture, so it still helps to verify wheel width and the exact size already associated with the sub-model. A 12-inch wheel does not automatically make every 12-inch tire the right choice. On a small car like the BMW 700, staying close to the intended size matters for appearance, clearance, and overall balance.
Do all 1965 BMW 700 sub-models use the same tire size?
No. The 1965 BMW 700 sub-models share some overlap, but they do not all use the same tire size. The LS Coupe uses 5.60-12 and 520-12, while the Sport & Cabrio uses 5.50-12 and 5.60-12. The shared size is 5.60-12, but each sub-model also has another size associated with it.
That overlap can make selection confusing if the car has been restored, modified, or fitted with replacement wheels in the past. Identifying the exact sub-model and confirming the wheel dimensions before choosing a tire is the safest approach. It also helps narrow whether the car should stay with a purely bias-ply replacement or whether the 520-12 application opens the door to radial-equivalent consideration.
Bias-Ply & Radial Options
Is 520-12 a bias-ply or radial tire for the 1965 BMW 700?
For the 1965 BMW 700, 520-12 is a primary bias-ply tire size. It is a vintage numeric bias-ply format used on a 12-inch rim, and available 520-12 products stay within that traditional construction. This size is associated with the LS Coupe and represents the original-style construction approach rather than a modern radial format.
A radial can still be considered, but it falls into the equivalent category rather than the primary fitment itself. That distinction matters because the decision is not just about diameter; wheel width, overall dimensions, and vehicle clearance should also be checked. Owners pursuing a period-style look often stay with bias-ply, while others may compare radial equivalents for road-use priorities.
What radial tire sizes are equivalent to 520-12?
The radial equivalents for 520-12 are 125R12 and P125/75R12. The 125R12 is a Euro-metric 80-series radial equivalent, while P125/75R12 is a P-metric 75-series radial equivalent. Both keep the 12-inch rim diameter and give buyers two different modern sizing conventions to compare against the original 520-12 bias-ply size.
A recommended rim-width range of 4 to 5 inches applies to these radial equivalents, so wheel width should be verified before considering a change in construction. It is also worth checking actual wheel condition, suspension clearance, and how closely the tire suits the car’s intended stance. Equivalent sizing is useful, but it should be treated as a fitment option to evaluate rather than an automatic substitute.
What should I check before converting my 1965 BMW 700 from bias-ply to radial tires?
Before converting a 1965 BMW 700 from bias-ply to radial tires, confirm that the car is using the 520-12 application, since that size has radial equivalents in 125R12 and P125/75R12. The wheel should also be checked for proper 12-inch diameter and a width that falls within the 4 to 5 inch rim-width range associated with those equivalent sizes.
Beyond the wheel itself, inspect clearance at the fenders and steering components and make sure the suspension is in sound condition. A collector car with worn bushings, tired springs, or non-original wheels can react differently than a stock car. The goal is to verify the whole setup, not just the nominal size, before moving away from the original bias-ply construction.
Choosing the Right Tire
What should I consider when choosing a 520-12 tire for a 1965 BMW 700?
Choosing a 520-12 tire for a 1965 BMW 700 starts with confirming that the car is an LS Coupe and that 520-12 is the correct size for its present wheel setup. From there, the main considerations are whether to stay with a traditional bias-ply tire and whether a blackwall or wide whitewall presentation better suits the car’s intended look.
Available 520-12 products also make it worth comparing details such as rim-width compatibility, load information when stated, and overall visual character. A car aimed at restoration-style presentation may call for a different sidewall treatment than one intended for casual driving and display. Matching the tire to both the sub-model and the use of the car leads to a more satisfying choice.
What sidewall styles are available for 1965 BMW 700 tires?
In the available 520-12 fitment for the 1965 BMW 700, sidewall choices include blackwall and wide whitewall. Both are offered within the BFGoodrich Silvertown Classic Bias Ply series, so the buyer is comparing appearance treatments within the same general vintage-style construction rather than choosing between unrelated modern tire categories.
That makes sidewall style an important visual decision, especially on a compact car where the tire is a noticeable part of the overall presentation. A blackwall gives a simpler, understated look, while a wide whitewall creates a more decorative period impression. The right choice depends on the look being pursued and how closely the owner wants the finished car to reflect a restoration-oriented theme.
What brands offer tires for the 1965 BMW 700?
The available products for the 1965 BMW 700 in 520-12 come from BFGoodrich. Those options are part of the Silvertown Classic Bias Ply series and include more than one sidewall treatment, giving buyers some choice within a single vintage-focused brand offering. This is a narrower product landscape than many larger American classics, which is typical for smaller specialty sizes.
With a limited brand spread, the buying decision becomes more about selecting the correct size and presentation than comparing a long list of manufacturers. It also places more importance on confirming whether 520-12 is the right fitment for the specific car. On a BMW 700, getting the sub-model and wheel setup right matters more than chasing variety for its own sake.
Restoration & Appearance
Which tire should I choose for a period-style 1965 BMW 700?
A period-style 1965 BMW 700 should begin with the correct primary bias-ply size for the exact sub-model: 5.60-12, 520-12, or 5.50-12 depending on the application. Staying within the proper vintage numeric bias-ply format keeps the car’s small-scale proportions and visual character much closer to its original-era presentation than an arbitrary modern substitute.
The final choice depends on how exact the restoration goal is and which wheel setup is on the car today. For owners pursuing a historically faithful look, vehicle-specific photos, marque references, and restoration records can help refine the final sidewall and appearance choice. Even when authenticity is not the main goal, beginning with the correct size is still the right foundation.
How does tire construction affect the appearance of a restored 1965 BMW 700?
Tire construction has a visible effect on a restored 1965 BMW 700 because the car’s compact proportions make the tire profile easy to notice. A bias-ply tire keeps the vehicle in the same general construction family as its original-era fitment, which helps preserve a traditional period-style look. That is especially relevant when the goal is a restoration-oriented presentation rather than simple transportation.
A radial equivalent can still be considered for the 520-12 application, but the visual impression may differ from a purely bias-ply setup. Sidewall shape, tread presentation, and overall stance can influence how authentic the finished car feels. For many restorations, the tire is one of the last details installed, yet it has an outsized effect on whether the car looks complete.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1965 BMW 700?
Yes. Modifications can affect tire fitment on a 1965 BMW 700 even when the wheel still measures 12 inches in diameter. Aftermarket wheels, changes in wheel width, suspension work, ride-height changes, or body repairs can all influence whether a vintage-size tire clears properly and sits as intended. That is especially important when the car already has more than one primary tire size across the range.
A modified car should be checked at the wheel openings and through the steering range before any replacement tire is chosen. It also helps to verify the actual wheel width, particularly if a radial equivalent is being considered for a 520-12 application. Small cars leave less room for assumptions, so fitment should be confirmed on the vehicle rather than guessed from appearance.
What should I inspect before driving a 1965 BMW 700 on new tires?
Before driving a 1965 BMW 700 on new tires, inspect the wheels for damage or corrosion, confirm that the tire size matches the sub-model, and make sure the tires are seated and inflated properly. It is also wise to check valve stems, wheel hardware, and general clearance around the fenders and steering components before the car goes back into regular road use.
A short, careful test drive is a smart next step, especially on a collector car that may have sat for long periods. Pay attention to tracking, vibration, and any sign of rubbing at low speed before moving into normal driving. If the car has not been on the road recently, a quick look at suspension wear and brake condition is just as important as the new tires themselves.
How should 520-12 tires on a collector 1965 BMW 700 be maintained?
520-12 tires on a collector 1965 BMW 700 should be maintained with regular pressure checks, routine visual inspection, and clean, dry storage conditions. Look closely for cracking, cuts, bulges, uneven wear, or slow air loss, since vintage-use vehicles often age out tires long before they wear out the tread. Keeping the car away from prolonged sunlight and ozone sources also helps preserve tire condition.
Periodic inspection matters even more when the car is driven only occasionally. A BMW 700 that spends most of its time parked can still develop tire issues from age, flat-spotting, or storage environment. Before any longer drive, confirm pressure, examine the sidewalls, and make sure the wheels and suspension still support the tire properly. Low-mile collector use does not eliminate maintenance needs.
