Goggomobil 700 Tires

The Goggomobil 700 belongs to the postwar wave of compact European economy cars that prioritized light weight, efficiency, and simple mechanical packaging. In 1961 and 1962, Goggomobil 700 buyers were dealing with a small-displacement car from an era when some models still bridged older bias-ply sizing and newer radial conventions. Tire selection is not entirely straightforward because the same Goggomobil 700 appears with both a numeric bias-ply size and a metric radial size, even though both fit 12-inch wheels. Before choosing tires for a Goggomobil 700, confirm whether the car is set up for its bias-ply specification or its radial alternative and verify the actual 12-inch wheel width on the car.

Goggomobil 700 Tire Size Guide

The Goggomobil 700 uses 2 distinct tire sizes across the 1961 to 1962 production span. Both sizes fit 12-inch wheels, but they represent two different sizing systems and two different construction approaches: a metric radial and a numeric bias-ply option. That difference matters because the car should be matched to the size and construction it is actually set up to use.

145R121961-1962Euro-metric radial

145R12 is a radial size used on 1961 to 1962 Goggomobil 700 models. The 145 indicates a section width of 145 millimeters, the R identifies radial construction, and the 12 is the required 12-inch rim diameter; the listed product is sized 145R12 72S TL and fits a 4.5-inch rim. Choose this size when the car is set up for the radial fitment and you want the modernized driving character of a radial while staying within the listed 12-inch wheel specification.

520-121961-1962Numeric bias-ply

520-12 is a numeric bias-ply size used on 1961 to 1962 Goggomobil 700 models. The 520 designation is the nominal section width with the decimal omitted, and the 12 is the required 12-inch rim diameter; listed products fit a 12-inch rim, with one product calling for a 4-inch rim width. Choose this size when the car is being kept in bias-ply form or restored to a more period-style setup, and note that a tube is required.

Goggomobil 700 Tires by Year

The year listing shows which tire sizes are associated with each Goggomobil 700 model year and helps narrow the choice between the radial and bias-ply options. In 1961 and 1962, two sizes are listed, reflecting a construction split rather than a wheel diameter change. These listings cover a short production window, so it is wise to confirm the specific wheel and setup on the car before settling on a tire.

Frequently Asked Questions

The questions below focus on the two-size split used on the Goggomobil 700, including how to tell the radial option from the bias-ply option and what to verify on a small 12-inch wheel before choosing tires.

Size Basics & Fitment

The Goggomobil 700 uses two listed tire sizes across 1961 and 1962: 145R12 and 520-12. Both sizes are associated with 12-inch rims, but they represent different tire systems. The 145R12 is a radial fitment with a listed 4.5-inch rim width, while the 520-12 is a bias-ply fitment with listed 12-inch rims and a 4-inch rim width on one product.

That means the key choice is not a year-to-year wheel diameter change, but whether your Goggomobil 700 is using the radial setup or the bias-ply setup. Check the size on the tire currently fitted, measure the wheel if needed, and compare the rim width before deciding. On a small car like the Goggomobil 700, those details matter more than simply matching the model year.

On the Goggomobil 700, 520-12 is a numeric bias-ply tire size. The 520 is the nominal section width with the decimal omitted, and the 12 identifies the rim diameter in inches. The listed products in this size are bias-ply tires for 12-inch rims, and one product specifies a 4-inch rim width.

Modern buyers often find this older sizing less intuitive than metric radial sizes, so it helps to think of 520-12 as an older construction and sizing convention rather than a direct modern metric equivalent. If your Goggomobil 700 is being restored with a traditional look and feel, this is the size to inspect closely. Because it is a bias-ply fitment, tube use should be part of the setup.

A 1961 Goggomobil 700 has two tire sizes listed because the car appears with both a 145R12 radial option and a 520-12 bias-ply option. The split is not caused by different wheel diameters, since both sizes use 12-inch rims. It is a construction and sizing-system split between a later-style radial designation and an older numeric bias-ply designation.

The practical takeaway is that year alone does not settle the question on a 1961 Goggomobil 700. Look at the wheel width, check what is mounted on the car now, and decide whether the goal is originality in a bias-ply format or a radial setup using the listed metric size. That will usually point you to the correct choice much faster than relying on model year alone.

The bias-ply 520-12 fitment for the Goggomobil 700 requires a tube. The radial 145R12 listing is a tubeless-design radial, shown by the TL marking in the listed size. Because the Goggomobil 700 appears with both constructions, tube use depends on which tire size and construction the car is actually using.

That distinction matters when replacing tires on a small collector car that may have older wheels. If your Goggomobil 700 is on 520-12 bias-ply tires, plan the tire and tube as a matched setup. If it is on 145R12 radials, make sure the wheels are appropriate for tubeless radial use and are in sound condition before the tires go into service.

Crossply vs Radial

The Goggomobil 700 is listed with both a crossply-style bias-ply size, 520-12, and a radial size, 145R12. Bias-ply is the more traditional construction and suits a period-style restoration, while the radial represents a newer tire design and uses a metric sizing convention. Both fit 12-inch rims, but the wheel width details differ between the listed products.

Choose the tire type that matches the way your Goggomobil 700 is configured and the way you intend to use it. A restoration that emphasizes period appearance will usually lean toward the bias-ply fitment, especially with whitewall availability. A driver-focused car may favor the radial, but the wheels, stance, and overall setup should be checked as a complete package before making the switch.

Yes, radial tires can change how a Goggomobil 700 feels on the road compared with bias-ply tires. The listed 145R12 radial and 520-12 bias-ply are different construction types, and that usually affects steering response, ride character, and the way the car follows road surfaces. On a very light car like the Goggomobil 700, those changes can be noticeable.

That does not automatically make one choice right for every owner. A Goggomobil 700 restored for period character may feel most appropriate on bias-ply tires, while a car driven more regularly may benefit from the manners of a radial setup. Keep all four tires in the same construction type so the car behaves consistently and predictably.

Mixing crossply and radial tires on a Goggomobil 700 is not a sound approach. The listed sizes are built on two different construction principles, and combining them can create uneven steering feel, inconsistent breakaway behavior, and mismatched ride characteristics. Even on a small and modestly powered car, those differences can upset the way the chassis responds.

A better practice is to keep the Goggomobil 700 on one complete tire system: either all 520-12 bias-ply or all 145R12 radial. That keeps the car balanced and simplifies pressure, maintenance, and wear monitoring. If you are changing from one construction to the other, treat it as a full-vehicle decision rather than replacing only one axle.

Buying the Right Tire

A 1962 Goggomobil 700 can use either 145R12 or 520-12, so the right size is confirmed by the actual wheel and the setup already on the car. Both are 12-inch fitments, but the 145R12 radial is listed on a 4.5-inch rim while the 520-12 bias-ply includes a 4-inch rim width listing. The construction type is the first clue, and the wheel width is the next one to verify.

Start with the tire sidewall if the existing tires are still readable, then inspect the wheel dimensions and compare the overall look of the car to your restoration goal. A bias-ply setup usually points toward 520-12, while a radial setup points toward 145R12. If the car has changed hands or been modified over the years, the wheel itself is often the most reliable guide.

Goggomobil 700 tires are listed in blackwall and wide whitewall sidewall styles. The 145R12 radial is available as a blackwall Michelin MX, while the 520-12 bias-ply size is available in both blackwall and a 2.00 inch whitewall BFGoodrich version. That gives owners the choice of a more understated driver appearance or a more period-flavored presentation.

For a utilitarian small European car, blackwall usually looks the most restrained and natural, especially on a radial setup. The whitewall bias-ply option can make sense if the goal is a more stylized period look or a restoration with extra visual presence. Sidewall style should be chosen with the same care as construction type so the tire looks correct on the finished car.

Two brands are represented for Goggomobil 700 tire fitments: Michelin and BFGoodrich. Michelin appears in the 145R12 radial size with the Michelin MX series, while BFGoodrich appears in the 520-12 bias-ply size with Silvertown Classic Bias Ply products. Those brand options also align with the two different construction types used on the Goggomobil 700.

That means brand choice is partly a fitment choice on this model rather than simply a styling preference. If your Goggomobil 700 is on the metric radial size, the Michelin option fits that role. If it is on the numeric bias-ply size, the BFGoodrich offerings are the relevant path, including both blackwall and whitewall versions.

The Goggomobil 700 is listed with two tire series: Michelin MX and Silvertown Classic Bias Ply. Michelin MX is the radial-series option in 145R12, while Silvertown Classic Bias Ply covers the 520-12 bias-ply offerings. The difference is not just branding; it reflects two distinct construction approaches and two different visual and driving-character outcomes.

For a Goggomobil 700 owner, that means the series name can help confirm whether a tire belongs to a driver-oriented radial setup or a traditional bias-ply restoration. The radial Michelin MX will generally suit an owner prioritizing later-style road manners. The Silvertown Classic Bias Ply line better suits an owner who wants the earlier construction style and the option of whitewall presentation.

Maintenance & Longevity

A Goggomobil 700 should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, solvents, and electric motors. Maintain the tires at their proper operating pressure during storage and keep the car on a clean surface rather than bare earth or damp concrete. If the car will sit for a long period, rolling it slightly from time to time helps avoid prolonged flat spotting.

Because the Goggomobil 700 is light, its tires are not heavily loaded, but long idle periods still age rubber and can harden compounds. If the car is stored for a season or more, inspect the sidewalls and tread before the next drive rather than assuming low mileage equals good condition. Collector cars usually age their tires out long before they wear them out.

Tires on a Goggomobil 700 should be inspected before each drive and more thoroughly at regular service intervals. Check inflation pressure, tread condition, sidewall cracking, bead area condition, and any signs of impact damage or uneven wear. On bias-ply 520-12 tires, also pay attention to tube-related issues such as slow pressure loss or irregular shape after storage.

Frequent inspection matters because collector cars often spend long periods parked, and problems tend to appear from age and inactivity rather than mileage. A quick look before moving the Goggomobil 700 can prevent running on a low tire or overlooking age cracks on a small-diameter casing. If the steering feel changes or the car begins to wander, inspect the tires before assuming the fault is elsewhere.

Tires on a Goggomobil 700 should be replaced when age, cracking, hardening, separation, or chronic air loss appear, even if the tread still looks usable. Collector-car tires often reach the end of safe service life because of time and storage conditions rather than mileage. That is especially important on a light car where old rubber can still look deceptively presentable.

Do not use tread depth alone as the decision point on a Goggomobil 700. A car that only sees occasional drives, local shows, or weekend use still needs tires with sound structure and flexible rubber. If there is any doubt about age or internal condition, replacement is usually the wiser course than trying to stretch the service life of a visibly aged tire.

Restoration & Authenticity

The Goggomobil 700 is associated here with two period-appropriate fitment paths: 520-12 in a bias-ply series and 145R12 in a radial series. That means the car sits in a transition point where both an older numeric bias-ply format and a newer radial format appear. The correct original-style choice for a specific Goggomobil 700 depends on how that individual car was equipped.

For a restoration, that makes original paperwork, period photographs, and marque-club knowledge especially helpful. Rather than assuming every Goggomobil 700 left the factory on the same construction type, compare your car’s wheels and restoration goal with those period references. On small imported cars, tire choice can noticeably change both stance and authenticity.

Yes, correct tire fitment can affect both the presentation and judged authenticity of a Goggomobil 700. Judges and knowledgeable enthusiasts often notice whether the car carries the right construction type, an appropriate sidewall style, and a size that suits the period of the vehicle. A mismatch between a restoration theme and the tire choice can stand out quickly on a compact car.

That does not mean every Goggomobil 700 must be restored the same way, but the tire should support the car’s stated purpose. A preservation car, show car, and driver may reasonably land on different choices between radial blackwalls and bias-ply styles. If show judging matters, use club standards and period references to guide the final decision.

A Goggomobil 700 can be restored with either blackwall or whitewall tires from the listed options, depending on the appearance you want to recreate. Blackwall is available in both the radial 145R12 and the bias-ply 520-12, while a 2.00 inch whitewall is offered in the 520-12 bias-ply size. That gives restorers a conservative or more decorative period look within the listed fitments.

For many Goggomobil 700 restorations, blackwall will look the most restrained and closest to the practical character of the car. The whitewall option makes the strongest visual statement and may suit a more stylized period presentation. Matching sidewall style to wheel finish, trim level, and the car’s overall restoration intent usually produces the most convincing result.

Safety & Road Use

A Goggomobil 700 can be driven on public roads when it is fitted with the correct size, the tires are in sound condition, and the rest of the car is mechanically ready for use. The listed fitments include both a radial 145R12 and a bias-ply 520-12, so safety starts with using a matched set in the proper construction and wheel width range. Tire age and overall condition matter as much as the size itself.

Before regular road use, inspect the tires closely and make sure the car tracks properly, brakes evenly, and holds air consistently. A small, light collector car can feel very different on aged bias-ply tires than on fresh radials. Public-road use is reasonable only when the entire tire and wheel package suits the actual setup of the Goggomobil 700.

Before driving a Goggomobil 700, check tire pressure, visible sidewall condition, tread condition, valve stems, and wheel security. Confirm that all four tires are the same size and construction type, since the Goggomobil 700 appears with both radial and bias-ply fitments. If the car uses 520-12 bias-ply tires, include tube condition and pressure retention in the inspection routine.

That pre-drive check is especially valuable after the car has been parked for weeks or months. Small-diameter tires can lose pressure without looking obviously low, and a collector car may have issues that only appear after storage. A few careful minutes in the garage can prevent damage to rare wheels and make the first miles in a Goggomobil 700 much more predictable.

A Goggomobil 700 should be driven at moderate speeds appropriate to the car’s age, light weight, and tire construction. If the car is on traditional 520-12 bias-ply tires, a conservative pace is wise because older-style construction typically asks more of the driver in steering feel and stability. A radial-equipped Goggomobil 700 may feel calmer, but the overall condition of the car still sets the real limit.

The safest approach is to treat speed as a function of the whole vehicle rather than the tire alone. Build confidence gradually, especially after a fresh restoration or after long storage, and pay attention to heat, wandering, or vibration. A Goggomobil 700 is best enjoyed within the comfortable range of its chassis, brakes, and tire setup rather than being pushed like a modern car.
