1959 Goggomobil Tire Fitment Guide

1959 Goggomobil vehicles use four distinct tire sizes, depending on model. The Roadster & Coupe uses 480-10, the Saloon uses 440-10, and the T700 uses either 125R12 or 4.80-12. The two passenger-car fitments mount on 10-inch wheels, while the T700 fitments mount on 12-inch wheels. Where listed, 480-10 uses a 3-inch rim and 440-10 uses a 3-inch rim, while one 125R12 radial product is approved for 3.0- to 4.0-inch rim widths.

That means a 1959 Goggomobil owner needs to identify the exact model before choosing a tire, because the size is not shared across the full range. The T700 also adds a construction decision, since its 12-inch fitments include both a bias-ply and a radial option. Checking the wheel diameter on the vehicle first is the quickest way to avoid crossing over between the 10-inch passenger-car tires and the 12-inch truck fitments.

On a 1959 Goggomobil, 480-10 is a numeric bias-ply size. The 4.80 figure is the nominal section width in inches, and the 10 identifies the wheel diameter in inches. In this year and make range, that size belongs to the Roadster & Coupe and is offered as a bias-ply tire rather than a radial.

A buyer reading 480-10 should think in terms of traditional small-car sizing from the period, not modern metric dimensions. It also helps explain why the Roadster & Coupe cannot simply share tires with the Saloon even though both use 10-inch wheels. Matching the printed size on the sidewall or the vehicle's fitment history is the right next step before narrowing down blackwall or whitewall appearance.

On a 1959 Goggomobil, 125R12 is a Euro-metric radial size used on the T700. The 125 is the section width in millimeters, the R indicates radial construction, and the 12 is the wheel diameter in inches. Available products in this size carry an S speed rating, which corresponds to a 112 mph ceiling, and they are marked TL for tubeless construction.

That code tells a buyer two things at once: the T700's wheel diameter is different from the 10-inch passenger-car models, and this fitment moves into a later-style radial format rather than period numeric bias-ply sizing. For owners using a T700 regularly, that difference can shape the entire character of the tire choice. It is still important to verify that the vehicle is actually running 12-inch T700 wheels before choosing this metric radial size.

On a 1959 Goggomobil, that choice applies to the T700 because it is the only model here associated with both a 12-inch radial and a 12-inch bias-ply fitment. The 125R12 is a radial size, while the 4.80-12 is a numeric bias-ply size. Michelin products listed in 125R12 are tubeless radials with an S speed rating, while 4.80-12 represents the traditional bias-ply direction for the same model.

Owners who want the T700 to present more like a period utility vehicle will usually gravitate toward the bias-ply fitment, while owners prioritizing a more contemporary road feel often lean toward the radial. The decision is not one to make across the whole 1959 Goggomobil range, because the Saloon and Roadster & Coupe do not use these 12-inch sizes. Start by confirming the model and wheel diameter, then decide whether originality or later-style road manners matters more for how the truck will be used.

1959 Goggomobil tires are available in several sidewall treatments, depending on size. The 480-10 Roadster & Coupe fitment comes in blackwall and wide whitewall, the 440-10 Saloon fitment is offered in wide whitewall, and the 125R12 T700 radial fitment comes in blackwall and narrow whitewall. That gives the range a mix of understated and more decorative period-style appearances.

Sidewall choice changes the look of a small vintage vehicle more than many buyers expect, especially on compact wheels where the sidewall is visually prominent. Wide whitewalls tend to emphasize late-1950s show presentation, while blackwalls feel more restrained and utility-oriented. Narrow whitewalls on the 125R12 radial split the difference and can suit a T700 owner who wants some period flavor without moving away from a radial construction.

Three brands appear in the available 1959 Goggomobil fitments. BFGoodrich covers the 480-10 Roadster & Coupe size, Excelsior covers the 440-10 Saloon size, and Michelin covers the 125R12 T700 radial size. Each brand is tied to a specific size here, rather than offering every fitment across the full 1959 Goggomobil model range.

That matters because brand choice begins with correct size and model identification, not the other way around. A Roadster & Coupe owner comparing blackwall versus wide whitewall will be doing so within BFGoodrich offerings, while a T700 owner considering the radial route will be looking at Michelin. Once the correct model-specific size is established, then it makes sense to compare the available sidewall style and construction within that fitment.

Known rim-width guidance for 1959 Goggomobil tires varies by size. The 480-10 Roadster & Coupe fitment is listed on a 3-inch rim, and the 440-10 Saloon fitment is also listed on a 3-inch rim. One available 125R12 T700 radial product specifies a 3.0- to 4.0-inch rim-width range. The 12-inch 4.80-12 bias-ply T700 size should be matched to the actual wheel on the truck before selection.

Rim width matters because it affects how the tire sits on the wheel and how the sidewall presents once mounted. Even when the wheel diameter is correct, a tire can still be the wrong choice if the rim is outside the approved width range for the product you are considering. Measuring the wheel already on the vehicle is a smart checkpoint, especially on older microcars and light trucks that may have been changed over the decades.

Tube requirements on 1959 Goggomobil tires depend on the specific size and product chosen. The listed 125R12 Michelin radial products for the T700 are marked TL, meaning tubeless. The 10-inch bias-ply products shown for 480-10 and 440-10 do not carry a TL marking here, so buyers should confirm the sidewall marking and wheel type before deciding on tube use.

On older vehicles, the wheel itself is part of the decision because a tubeless-capable tire and an older wheel are not always the same thing. A restorer working with original rims should verify whether the wheel condition and design are appropriate for tubeless service or whether a tube is part of the intended setup. Checking that detail before mounting is far easier than correcting it after the tire is installed.

A 1959 Goggomobil should be stored out of direct sunlight, away from electric motors or other ozone sources, and in a dry space with stable temperature if possible. Clean tires and proper inflation help them hold shape during storage. Bias-ply tires, which appear on several 1959 Goggomobil fitments, are more prone to temporary flat-spotting during long static periods than radial tires like the T700's 125R12 option.

Moving the vehicle periodically or supporting it appropriately during long-term storage can reduce stress on the casing and help preserve ride quality. Owners of very light collector cars sometimes overlook storage discipline because the vehicle is small, but age and environment still matter more than weight. Keeping the tires off wet concrete, away from petroleum contamination, and protected from ultraviolet exposure will do more for longevity than infrequent cosmetic cleaning.

Tires on a 1959 Goggomobil should be judged by age and condition more than mileage, since collector vehicles often accumulate very few miles each year. A good rule is to begin close evaluation once tires are in the five- to seven-year range and to treat around ten years as a serious replacement point regardless of remaining tread. The DOT date code on the sidewall is the best starting reference for age.

That approach is especially important on a lightly used microcar or utility vehicle because old tires can look acceptable while the internal structure and rubber compounds are already aging out. A show-only car is not exempt from this concern. If a 1959 Goggomobil still wears older reproduction tires from a previous restoration, confirming the date code before the next season is smarter than relying on appearance alone.

Tires on a 1959 Goggomobil deserve a quick inspection before every drive and a more thorough inspection before any longer outing. Check for sidewall cracking, tread separation, cuts, bulges, irregular wear, and pressure loss. If the vehicle is running tube-type bias-ply fitments, valve stem condition and any signs of slow leakage deserve extra attention because small tires can show pressure changes quickly.

Frequent inspection matters because a vintage microcar often sits for long periods and then returns to service in bursts, which is exactly the pattern that can hide age-related issues. A five-minute walkaround can catch problems before they become roadside failures. It is also worth inspecting the spare at the same time, since a tiny original-style spare that has aged in place for years may not be a dependable fallback.

A 1959 Goggomobil Saloon would have been associated with a bias-ply tire rather than a radial as original-era practice, and the listed size for the Saloon is 440-10. That matches what buyers would expect from a late-1950s microcar, when small European economy vehicles commonly used compact bias-ply fitments. Original-equipment branding can vary by market and should be confirmed through marque references if exact presentation matters.

For restoration work, the most important first step is matching the Saloon to its correct size and construction before worrying about cosmetic details. Once that baseline is right, sidewall treatment becomes the next authenticity question, especially on a vehicle where whitewall choice can strongly influence appearance. Owners preparing a judged car should compare their intended tire to period photos, factory literature, and model-specific club knowledge for the market where the car was delivered.

Correct tire fitment matters on a 1959 Goggomobil because judges and knowledgeable enthusiasts often notice size, construction type, and sidewall style immediately on small cars where the wheel opening is visually dominant. A Saloon wearing the wrong 10-inch size or a T700 shown with a later-style radial when an event expects factory-style presentation can stand out for the wrong reasons. Whitewall treatment can also affect how authentic the finished vehicle looks.

Show standards are not always identical, so event rules and marque-club guidance should shape the final decision. A local casual show may be tolerant of tasteful updates, while stricter originality judging may expect the era-correct construction and a sidewall style consistent with the car's market and restoration goal. Getting the model-specific size right is the baseline; after that, sidewall appearance and construction become the details that sharpen authenticity.

For the 1959 Goggomobil T700 in 125R12, the Michelin X radial is offered in both blackwall and narrow whitewall form. Both are radial 125R12 62S TL tires, so the core construction, size, and S speed rating remain the same. The visible distinction is the sidewall treatment, and one listed narrow-whitewall version also specifies a 3.0- to 4.0-inch rim-width range.

That makes the choice more about presentation than about changing the basic fitment class of the tire. A blackwall keeps the truck's appearance plainer and more work-oriented, while a narrow whitewall adds a more styled period flavor without leaving the Michelin X radial family. Owners aiming for a particular restoration look should compare that appearance to period photos of similarly equipped T700s before making the final call.

1959 Goggomobil tires can be suitable for highway use when the tire is in good condition, correctly inflated, and matched to the vehicle's wheel and intended use. The listed 125R12 Michelin radial products carry an S speed rating, which corresponds to a 112 mph ceiling. The bias-ply fitments shown for the 10-inch passenger models and the 4.80-12 T700 size should be approached with the normal expectations that come with vintage-style construction and older vehicle dynamics.

In real use, the vehicle's own brakes, suspension design, wheel condition, and overall mechanical state usually matter as much as the tire itself on a late-1950s Goggomobil. A healthy tire does not override the limits of a very small vintage car or truck. Owners planning sustained higher-speed use should choose a tire whose construction and rating suit that use, then make sure the rest of the vehicle is equally ready for it.

Inflation pressure on a 1959 Goggomobil should follow the vehicle's factory recommendation first, then be checked against the chosen tire's own rating information. The listed 480-10 BFGoodrich products show a maximum load of 520 pounds at 32 psi. Pressure should not be transferred from one size to another, especially across different constructions and wheel diameters such as the 10-inch bias-ply passenger-car fitments and the 12-inch T700 options.

That matters because maximum sidewall pressure is not automatically the same as the correct running pressure for your particular model. A Saloon, Roadster & Coupe, and T700 place different demands on their tires, and radial versus bias-ply behavior can also influence how the vehicle feels when inflated properly. Checking the owner's manual, any factory literature, and the tire maker's marked limits together is the safest way to arrive at the final number.

Before a longer drive in a 1959 Goggomobil, inspect each tire for cracking, cuts, bulges, uneven wear, and proper inflation, and make sure the spare is serviceable as well. If the vehicle uses a tube-type setup, inspect valve stems closely and pay attention to any recent pressure loss. Wheel fasteners, wheel condition, and signs of rubbing or clearance issues should also be checked before setting out.

A longer outing in a small vintage vehicle is also the right time for a broader mechanical once-over that includes brakes, steering, fluid levels, and lighting. Tires are only one part of the preparation, but they are one of the easiest areas to inspect before trouble starts. A careful pre-drive routine is especially worthwhile on a Goggomobil because its light weight and compact size can make a tire problem feel abrupt once the car is already on the road.
