1962 Goggomobil Tire Fitment Guide

1962 Goggomobil vehicles use four sizes split across two models. The Goggomobil 700 uses 145R12 in radial form or 520-12 in bias-ply form, while the Goggomobil T700 uses 125R12 in radial form or 4.80-12 in bias-ply form. Every one of those sizes mounts on a 12-inch rim, but the fitments are not shared across both models.

That means year and make alone are not enough to choose correctly. Start by confirming whether your car is a 700 or a T700, then match the tire to the wheel and the type of driving you expect to do. If you are comparing radial and bias-ply options, verify the actual rim width of the wheel on the car before ordering, especially on a small-bodied microcar where wheel changes over the years are common.

On a 1962 Goggomobil, 520-12 is a numeric bias-ply tire size. The 5.20 portion refers to the nominal section width in inches, and the 12 refers to the wheel diameter in inches. That format belongs to the older American and European bias-ply sizing style commonly seen on small cars of the era.

For a Goggomobil 700 owner, that code signals a more traditional construction choice than a metric radial. It is useful when you want the stance, sidewall shape, and period character associated with early-1960s fitment. A numeric bias-ply size should not be treated as interchangeable with a different model's narrower T700 size simply because both use a 12-inch rim.

On a 1962 Goggomobil, 145R12 and 125R12 are euro-metric radial tire sizes. The first number is the nominal section width in millimeters, the R identifies radial construction, and the final 12 is the wheel diameter in inches. In this older metric style, the profile is not printed, and it is conventionally understood as an 80-series radial.

Those markings matter because they point to a different construction and driving character than the period-style bias-ply alternatives. The 145R12 belongs to the 700, while the narrower 125R12 belongs to the T700. If your goal is to keep the car easy to use on ordinary roads without changing away from a 12-inch wheel, the metric radial sizes are the natural place to start.

For a 1962 Goggomobil 700, the choice between 145R12 and 520-12 is mainly a construction choice, not a wheel-diameter change. The 145R12 is a radial, while the 520-12 is a bias-ply. Both fit the 700's 12-inch wheel diameter, but they deliver a different feel and visual character because of their construction and sizing conventions.

Owners who want a more original early-1960s presentation often lean toward the 520-12 bias-ply, especially if sidewall styling is part of the restoration plan. Owners who expect more regular road use usually gravitate toward the 145R12 radial for a more familiar modern response. The same logic applies to the T700's 125R12 versus 4.80-12 choice, but those sizes are model-specific and should not be swapped across the two models.

1962 Goggomobil tires are available in several sidewall styles depending on size. The 145R12 radial comes in blackwall, the 520-12 bias-ply comes in blackwall and wide whitewall, and the 125R12 radial comes in blackwall and narrow whitewall. That gives the 700 and T700 different visual options even though both use 12-inch wheels.

For a small early-1960s European car, blackwall is usually the most restrained and broadly era-appropriate look, while whitewall variations create a more stylized presentation. A wide whitewall on the 520-12 changes the personality of a Goggomobil 700 more dramatically than a blackwall version, and the narrow whitewall 125R12 gives the T700 a subtler accent. Match the sidewall style to the car's restoration theme rather than choosing on appearance alone.

Michelin and BFGoodrich both cover 1962 Goggomobil fitments, but they do so in different size families. Michelin supplies the radial sizes, with 145R12 for the 700 and 125R12 for the T700. BFGoodrich covers the 520-12 bias-ply size used on the 700.

That brand split reinforces the main buying choice on this year and make. If you are staying with radial construction, Michelin is the relevant path for the sizes used here. If you are restoring a 700 around a traditional bias-ply presentation, BFGoodrich is the brand tied to that numeric size. Always choose the brand only after confirming the exact model and size, since the 700 and T700 do not share the same radial or bias-ply dimensions.

Rim-width guidance is available for several 1962 Goggomobil sizes. The 145R12 radial uses a 4.5-inch rim width, the 520-12 bias-ply uses a 4-inch rim width, and the 125R12 radial is suited to a 3.0-to-4.0-inch rim-width range. All of those tires mount on 12-inch-diameter wheels.

That matters because wheel diameter alone does not settle fitment. A 12-inch wheel can still be the wrong match if its rim width falls outside the tire's intended range. On cars as small as a Goggomobil, even modest width differences can change sidewall shape and clearance, so it is worth measuring the actual wheel before final selection if the car's wheels may have been changed at some point.

Tube requirements on 1962 Goggomobil tires depend on the exact size and product. The 145R12 and 125R12 radial products are tubeless, marked TL. The bias-ply 520-12 products do not carry a TL or TT marking here, so tube use should be confirmed against the specific tire and the condition and design of the wheel being used.

On an older small imported car, tire construction and wheel design need to be considered together. Even when a tire is tubeless by design, an original wheel's condition, bead seat, and valve setup still matter. If you are fitting a bias-ply size or working with unrestored wheels, check the product's sidewall marking and the wheel's suitability before mounting rather than assuming every 12-inch Goggomobil wheel should be handled the same way.

Original 1962 Goggomobil wheels can often be retained across the available tire choices because every size used on the 700 and T700 is built for a 12-inch rim diameter. That means wheel diameter compatibility is consistent across 145R12, 520-12, 125R12, and 4.80-12, even though the two models use different overall tire sizes.

Rim width still needs to be checked before treating all 12-inch wheels as interchangeable. The 700 and T700 do not share the same radial or bias-ply dimensions, and the narrower T700 fitment should not be assumed to suit a wheel set up for the 700. Confirm the wheel's actual width and compare it with the intended tire before making a final choice.

A 1962 Goggomobil should be stored in a cool, dry, dark place away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone sources that accelerate rubber aging. Keep the tires clean, maintain proper inflation, and move the car periodically if it will sit for long stretches. Bias-ply tires are especially prone to temporary flat-spotting during static storage, while any collector tire can suffer from sidewall cracking if exposed to heat and ozone.

Because a Goggomobil is so light, owners sometimes overlook storage pressure and wheel position, but those details still matter. If the car will remain parked for months, occasional rolling or carefully supporting the vehicle can reduce stress on one contact patch. A breathable indoor cover helps the car overall, but tire life depends more on environment, pressure, and avoiding long-term exposure to sunlight and ozone.

Tires on a 1962 Goggomobil should be judged more by age and condition than by mileage. Collector-car tires are often inspected closely after about five to seven years of service, and many owners begin serious replacement consideration by around ten years regardless of remaining tread. The DOT date code on the tire is the starting point for that timeline.

A low-mileage microcar can still be riding on old rubber that looks acceptable from a distance but is no longer trustworthy for regular road use. Heat cycles, storage conditions, inflation history, and long parked periods all affect service life. If the car has recently changed hands, checking tire age should be one of the first steps before any extended driving, even if the tread depth appears generous.

Tires on a 1962 Goggomobil deserve a quick inspection before every drive and a more thorough one before any longer outing. Look for cracking, bulges, cuts, irregular wear, and pressure loss, and examine the tread and sidewall closely because small-car tires can age out long before they wear out. If your setup uses tubes, valve stems and any signs of slow leakage deserve extra attention.

That routine is especially important on a seldom-driven collector car because deterioration often appears gradually between outings. A brief walk-around catches obvious problems, but a hands-on inspection with a pressure gauge tells you much more. If the steering suddenly feels different, the car wanders, or one corner sits lower after storage, investigate before driving rather than assuming it is normal old-car behavior.

A 1962 Goggomobil 700 would have been associated in period with bias-ply construction as the standard type for most small economy cars, even though a radial option now exists in the correct 12-inch diameter. Within current 700 fitments, the bias-ply size is 520-12 and the radial alternative is 145R12. No original-equipment brand should be assumed from size alone.

For an owner restoring a 700 toward factory character, the bias-ply size is the first place to look. If the car has market-specific history, dealer-installed accessories, or regional delivery details that matter for judging, consult a Goggomobil club or marque specialist before finalizing sidewall style and construction. That extra step is worthwhile because tiny imported cars often have more variation in surviving examples than larger domestic collector cars.

Correct tire fitment absolutely matters when showing a 1962 Goggomobil, especially in preservation or concours-oriented settings. Judges and knowledgeable enthusiasts often notice whether the tire size, construction type, and sidewall style match the period character of the car. On a microcar, an overly modern-looking sidewall or the wrong size can alter the car's stance enough to stand out immediately.

For a 700 or T700 presented as an authentic restoration, the safest path is to match the model-specific size first, then choose the sidewall treatment that suits the car's intended period appearance. A radial may be entirely sensible for driving use, but it can still be viewed differently from a bias-ply tire in originality-focused judging. Event standards vary, so marque clubs and show rulebooks are the best final reference.

A 1962 Goggomobil T700 belongs to an era when bias-ply tires were still the normal original construction on small production cars, even though a radial replacement exists today. The model-specific bias-ply size is 4.80-12, while the radial alternative is 125R12. Both keep the T700 on a 12-inch rim, but they represent different eras of tire design.

If historical appearance is the priority, begin with the 4.80-12 bias-ply path and then refine the choice around wheel condition and the car's presentation goals. If the T700 is being built for regular use rather than strict originality, the 125R12 radial may be easier to live with while preserving the proper wheel diameter. A model-specific check matters here because the T700's narrower sizes are not shared with the 700.

1962 Goggomobil tires can be suitable for highway use when they are the correct size, in sound condition, and used within their design limits. The radial 145R12 and 125R12 products carry an S speed rating, which corresponds to a 112 mph ceiling. That rating is well above the real-world cruising ability of a tiny early-1960s Goggomobil, where braking, stability, suspension condition, and overall mechanical health are usually the more meaningful limits.

Construction still affects how the car feels on the road. A radial-equipped Goggomobil will generally feel different from one on bias-ply tires, especially on crowned pavement or in crosswinds, but either setup needs to be matched to the model and kept in excellent condition. Before regular highway use, inspect age, inflation, wheel condition, and alignment rather than focusing on the speed rating alone.

Inflation pressure for a 1962 Goggomobil should begin with the factory recommendation for the specific model, then be checked against the tire manufacturer's own rated limits. One 520-12 bias-ply version carries a maximum load of 694 pounds at 30 psi. That figure is a load-and-pressure limit for that tire, not a universal inflation setting for every 1962 Goggomobil size.

The safest approach is to treat each size on its own terms. Do not transfer a pressure figure from 520-12 to 145R12, from 125R12 to 4.80-12, or from one model to the other simply because all four sizes use a 12-inch rim. Use the owner's manual as the baseline for vehicle setup, and confirm the tire's own sidewall information before final adjustment.

Before a longer drive in a 1962 Goggomobil, inspect each tire for cracking, cuts, bulges, uneven wear, and correct cold inflation pressure. Check the valve stems, confirm the spare is serviceable, and make sure the wheel fasteners and wheel condition are sound. Tire preparation should be part of a broader old-car check that also includes brakes, steering, lights, fluids, and charging system health.

A Goggomobil's small size makes it tempting to treat it like a simple runabout, but longer trips put more sustained load and heat into vintage tires than local drives do. If the car has been stored for a while, take a short shakedown run first and recheck pressures afterward. Catching a weak valve stem, an aging spare, or a sidewall issue in the garage is much easier than dealing with it roadside.
