1963 BMW Tire Fitment Guide

1963 BMW vehicles use nine tire sizes spread across six models. The 1500, 1600/4, and 1800 use 165R14 or 6.00-14 on 14-inch rims. The 2600 uses 185R15 or 640-15 on 15-inch rims. The 3200 uses 6.50-15 or 670-15 on 15-inch rims. The 700 uses 5.60-12, 520-12, or 5.50-12 on 12-inch rims. Rim width guidance appears on some products, including 165R14 at 4.0 to 6.0 inches depending on tire, 185R15 at 4.5 to 6.5 inches, 640-15 at 4.0 to 5.0 inches, 670-15 at 4.5 to 6.0 inches, and 520-12 at 4 inches.

The practical takeaway is that year and make alone are not enough for a 1963 BMW. A BMW 700, a Neue Klasse sedan, and a large six-cylinder saloon all sit in different tire families, so confirming the exact model is the first step. After that, check the wheel diameter already on the car and compare the tire size stamped on any surviving spare or service records. That process usually narrows the choice quickly before you even get into sidewall style or construction preferences.

On a 1963 BMW, 165R14 is a classic Euro-metric radial size. The 165 refers to a nominal section width of 165 millimeters, the R identifies radial construction, and the 14 is the wheel diameter in inches. In this older metric format, no aspect ratio is printed, and the size is generally understood in the vintage market as an approximately 80-series profile. On 1963 BMW models, 165R14 belongs to the 1500, 1600/4, and 1800 rather than the whole model range.

That decoding matters because 165R14 is not simply a modern compact-car tire size wearing an old label. It points to a particular period radial format used on early BMW sedans and should be matched to the correct 14-inch wheel. If you are comparing it with 6.00-14, the difference is not just the numbers on the sidewall but the tire's construction and driving feel. Checking the wheel width against the tire maker's approved range is the next smart step before making a final selection.

No. 1963 BMW models use different tire sizes depending on the model family. The 1500, 1600/4, and 1800 share 165R14 and 6.00-14, the 2600 uses 185R15 and 640-15, the 3200 uses 6.50-15 and 670-15, and the 700 uses 5.60-12, 520-12, and 5.50-12. That spread covers three different rim diameters and several very different carcass and sidewall styles.

This is especially important for buyers who know they have a 1963 BMW but have not yet pinned down the exact model or are working from a project car with changed wheels. Two cars from the same model year can require completely different wheel diameters and very different tire proportions. Start with the model identification plate, then inspect the wheels already on the car, and use the current tire size only as a clue rather than a final answer if the car may have been altered over the years.

For a 1963 BMW 1500, 1600/4, or 1800, the choice between 165R14 and 6.00-14 is mainly a choice between radial and bias-ply construction. The 165R14 is a period-style metric radial on a 14-inch wheel, while the 6.00-14 is a traditional numeric bias-ply size on the same wheel diameter. That means the decision is not about one fitting a completely different wheel family, but about whether you want radial behavior or a more original early-1960s construction style.

Owners building a show-oriented sedan often lean toward the bias-ply route because it aligns more closely with the era's original construction language. Owners who plan to drive their BMW more regularly often prefer the radial option for its more familiar road manners. Neither choice should be made by sidewall appearance alone, though. Confirm the wheel width, decide how the car will be used, and keep the tire construction consistent across the axle set so the car behaves predictably.

Sidewall style depends heavily on the tire size used by the specific 1963 BMW model. The 165R14 radial options for the 1500, 1600/4, and 1800 are blackwall. The 185R15 radial for the 2600 appears in blackwall, redline, and narrow whitewall versions. The 640-15 bias-ply for the 2600 is available in wide whitewall and narrow whitewall form, while 670-15 for the 3200 appears in blackwall and wide whitewall. The 520-12 size used on the 700 is available in blackwall and wide whitewall.

Appearance should follow both the car's era and the look you are trying to achieve. A blackwall usually reads as the most understated and sporting choice on many European sedans, while redlines and whitewalls create a more stylized period presentation. Because different sidewall treatments can change the visual balance of a classic BMW substantially, it is worth comparing them against factory brochures, period photos, or marque-club references before committing to a look for a restoration.

Several brands cover 1963 BMW tire sizes, depending on the model and size family. The 165R14 radial is available from Pirelli, Michelin, and Vredestein. The 185R15 radial for the 2600 comes from Coker Classic and Michelin. The 640-15 bias-ply size appears from BFGoodrich and Firestone. The 670-15 bias-ply size for the 3200 is available from Firestone, US Royal, Coker Classic, and Universal Vintage Tire. The 520-12 size for the BMW 700 appears from BFGoodrich.

Brand choice often comes down to how closely you want to align with a particular period look, road character, or sidewall treatment rather than just the name on the casing. European radial names such as Michelin and Pirelli are a natural fit visually and historically on many 1960s BMWs, while American bias-ply brands often offer broader whitewall presentation options. Once you narrow the correct size for your model, compare the available sidewall styles, speed ratings where applicable, and approved wheel-width ranges before making the final call.

Rim width guidance varies by tire size on 1963 BMW vehicles. For 165R14, approved widths run from 4.0 to 6.0 inches depending on brand. For 185R15, the range runs from 4.5 to 6.5 inches depending on tire. For 640-15, the published ranges span 4.0 to 5.0 inches. For 670-15, they span 4.5 to 6.0 inches. The 520-12 size shows a 4-inch rim width. Other sizes here do not carry a wheel-width comparison on this page.

That range matters because a tire can physically mount on a wheel yet still sit outside the manufacturer's intended profile if the rim is too narrow or too wide. Before choosing among products in the same size, measure the actual wheel on the car rather than relying on memory or a past owner's note. On a restored or modified BMW, wheel swaps are common enough that this one check can prevent a mismatch in sidewall shape, steering feel, and visual stance.

Inner-tube requirements vary by tire size and even by product within some 1963 BMW applications. The Michelin examples in 165R14 and 185R15 are marked TL, which indicates tubeless construction. Other products in those same radial sizes do not all carry the same marking on the sidewall information shown here, so tube status varies by product. The bias-ply sizes shown here do not consistently state tube or tubeless status in the product markings on this page.

The safest approach is to treat tube use as a wheel-and-tire system decision rather than a tire-size assumption. If your BMW still has original wheels, especially older riveted or specialty rims, confirm whether the wheel itself is suitable for tubeless use. If you are choosing a radial in 165R14 or 185R15, read the exact sidewall marking for the individual tire and pair that with the wheel's condition and design. A marque specialist or experienced vintage tire installer can help settle borderline cases.

On the 1963 BMW 1500, 1600/4, and 1800, both 165R14 and 6.00-14 use 14-inch wheels, so the original wheel diameter is consistent between those two size paths. On the 1963 BMW 2600, both 185R15 and 640-15 use 15-inch wheels. The 3200's two sizes are also both 15-inch, and the 700's three sizes are all 12-inch. That means wheel diameter compatibility within each model family is straightforward.

Wheel diameter alone does not settle the whole question, though. Rim width still needs to line up with the specific tire's approved range, and that range can vary even within one size depending on brand and construction. If your BMW still carries its original steel wheels, inspect width, bead condition, and any signs of previous repairs before moving between size options. That check is especially worthwhile when switching between bias-ply and radial tires on the same model.

A 1963 BMW should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that age rubber. Keep the tires properly inflated and move the car periodically if it sits for long stretches. Bias-ply tires, which appear across most 1963 BMW fitments here, are especially prone to temporary flat-spotting after long static storage, while radials generally recover more quickly.

If the car will sit for a season or longer, many collectors either roll it a short distance every few weeks or place it on stands so the suspension is supported and the tire sidewalls are not carrying the full load continuously. Clean the tires with mild soap and water only, and avoid dressings that leave a glossy coating. Good storage habits matter as much as mileage on a collector BMW because age and environment often drive tire deterioration more than wear.

Tires on a 1963 BMW should be judged more by age and condition than by mileage. On a collector car, many owners begin evaluating tires closely once they reach five to seven years of age, and replacement becomes a serious consideration by around ten years regardless of remaining tread. The DOT date code on the tire sidewall is the most reliable guide to age, especially on cars that are driven sparingly and may still look good at a glance.

A lightly used BMW can age out its tires long before it wears them out. Sidewall cracking, hardening rubber, recurring air loss, and changes in ride quality are all stronger replacement signals than tread depth alone on a vintage car. If the car came with old tires of unknown age, checking the date codes should be part of the first inspection along with brakes, hoses, and fuel lines. That approach helps separate cosmetic preservation from real road readiness.

Tires on a 1963 BMW deserve a quick inspection before every drive and a more thorough inspection before any extended outing. Look for sidewall cracking, cuts, bulges, uneven tread wear, and any sign that the tire is not holding pressure consistently. On sizes that may involve tube-type setups, valve stems and tube condition also deserve attention because slow leaks can start there as easily as in the casing itself.

A short pre-drive walkaround catches problems while they are still small and manageable. For a longer trip, check cold inflation pressures, inspect the spare, and verify that the tires have not developed age-related cracking on the inward-facing sidewalls where damage can be missed. Classic BMWs often spend weeks between drives, and that stop-start usage pattern can hide deterioration until the next highway run. Frequent inspections are one of the simplest ways to make an infrequently used car safer and more predictable.

A 1963 BMW 1500 would have belonged to an era when bias-ply construction was still standard equipment on many cars, even as radial technology was becoming increasingly important in Europe. Within the fitments used on the 1500, both 6.00-14 bias-ply and 165R14 radial sizes are part of the period size picture. That makes the original-equipment question partly one of market, production timing, and regional specification rather than a single universal answer.

For a careful restoration, the right next step is to compare your car's surviving paperwork, handbook references, trunk decals, or period BMW literature against the wheel and tire setup already on the car. If the goal is concours-level accuracy, consult a BMW marque club or model specialist because judges may distinguish between correct size family, correct construction type, and correct sidewall appearance. The broad rule is simple: bias-ply is more traditional for the era, while radial fitment reflects the transitional European context.

Correct tire fitment matters on a 1963 BMW because judges and knowledgeable enthusiasts often notice tire size, construction type, and sidewall style immediately. A BMW 700 on an incorrect 14- or 15-inch tire would stand out just as quickly as a large 3200 wearing a size intended for a smaller sedan. Construction can matter as well, since a modern-looking radial can read differently from a period bias-ply tire on a car judged for originality.

The level of scrutiny depends on the event. A casual local show may reward presentation more than strict authenticity, while marque judging can be far more particular about size family and period-correct appearance. If originality is important, match the tire not only to the right model but also to the visual character expected for that specific BMW. Club judging manuals, factory literature, and experienced restorers are the best sources when the car sits in a gray area between period radial adoption and earlier bias-ply practice.

For the 1963 BMW 2600 in 185R15, Michelin XVS and Coker Classic Radial differ in sidewall presentation, speed rating detail, and published wheel-width range. Michelin XVS appears in blackwall and narrow whitewall form, with H-rated and V-rated examples marked TL and wheel-width ranges from 4.5 to 6.5 inches depending on version. The Coker Classic radial appears here as a redline tire with a 5.0 to 6.5 inch wheel-width range and a published load figure of 1,355 pounds at 35 psi.

That means the choice is not simply brand preference. Michelin gives the 2600 owner a more European touring-style presentation and explicit speed-rating options, while the Coker Classic redline introduces a distinctly different visual statement in the same size family. Wheel width should be checked before choosing between them, especially if the car has non-original wheels. If appearance is the top priority, decide first whether you want blackwall, narrow whitewall, or redline, then narrow the field from there.

1963 BMW tires can be suitable for highway driving when the tire's condition, size, and speed rating match the way the car is being used. The radial choices here include H-rated tires with a 130 mph ceiling and a V-rated 185R15 Michelin at 149 mph, while many bias-ply sizes on the page do not show a speed rating in the sidewall marking information. For normal highway use, the tire's age and condition are often more important than its theoretical maximum speed.

The broader reality is that a 1963 BMW's braking system, suspension condition, steering wear, and alignment can limit confidence long before a fresh reproduction tire reaches its speed ceiling. That is especially true on cars that have sat for years or are newly returned to the road. If highway use is part of the plan, inspect the entire chassis and keep expectations in line with the car's era. A correctly sized, healthy tire is only one part of making a vintage BMW roadworthy.

Inflation pressure on a 1963 BMW should follow the vehicle's factory recommendations first, then stay within the tire maker's published maximum load-and-pressure limits for the specific tire you choose. Several tires here include reference figures: 165R14 Vredestein at 1,102 pounds at 51 psi, 185R15 Coker Classic at 1,355 pounds at 35 psi, 640-15 examples up to 1,190 pounds at 32 psi, 670-15 examples up to 1,550 pounds at 32 psi, and one 520-12 example at 694 pounds at 30 psi.

Those numbers are load-and-maximum-pressure references, not a universal setting to copy across every 1963 BMW. A 700, a 1500, and a 3200 place very different demands on their tires, and even two tires in the same nominal size can carry different specifications. The best practice is to start with the period BMW recommendation for your exact model, then verify that the chosen tire's construction and load range support that use. Never transfer a pressure figure casually from one size family to another.

Before a longer drive in a 1963 BMW, inspect all four tires and the spare for cracking, cuts, bulges, uneven wear, and proper cold inflation pressure. Look closely at valve stems, especially if the car may use tube-type assemblies, and confirm that the tires are seated evenly on the wheels. On cars with radial options such as 165R14 or 185R15, verify the exact sidewall marking so you know whether the tire is tubeless and what speed rating it carries.

Tires are only one part of the pre-trip routine on a car of this age. Wheel-bearing play, brake function, steering looseness, and old suspension bushings can all change how the car feels at speed even when the tires are new. If the BMW has been sitting, take it on a short local drive first and recheck pressures afterward. That staged approach helps expose slow leaks, flat-spot recovery, and any vibration before the car is committed to a longer outing.
