1967 Opel Tire Fitment Guide

1967 Opel vehicles use one tire size across the model range covered here: 155R13, fitted to the Kadett. That size mounts on a 13-inch wheel, and the available radial products for it are built around a rim width range of 4.00 to 5.50 inches where that specification is stated. Because there is only one size in use for the year and make, there is no model-to-model size split to sort through.

That simplicity is helpful, but it still pays to confirm that your Kadett has the correct 13-inch wheels before choosing a tire. Many older imports have seen wheel changes over the decades, especially cars that were modified for local road use or cosmetic updates. If your car still wears its original-style wheel dimensions, 155R13 is the natural place to begin.

On a 1967 Opel tire, 155R13 is a euro-metric radial size. The 155 refers to a nominal section width of 155 millimeters, the R identifies radial construction, and the 13 is the wheel diameter in inches. Because this format does not spell out an aspect ratio, it is conventionally treated as an 80-series metric radial unless a different profile is specifically marked.

For a Kadett owner, that decoding matters because it explains why the tire looks relatively narrow and tall compared with later low-profile metric sizes. That shape is part of the way many European compacts of the 1960s sat and steered. If you are comparing tires visually, make sure you are matching the full 155R13 size rather than only the 13-inch rim diameter.

Yes. The 1967 Opel range covered here uses the same 155R13 tire size across its model lineup, with the Kadett being the model represented for that year. That means you do not need to sort between multiple factory size families before narrowing down product choices. The fitment question is straightforward compared with many American makes of the same era.

What can still change from one car to another is the owner’s goal for the vehicle. A carefully restored Kadett, a weekend driver, and a car meant for occasional touring can all use the same basic size while favoring different tread designs or brand preferences. Once size is confirmed, the next step is choosing the tire character that matches how your Opel is driven and presented.

1967 Opel tires in 155R13 are available in blackwall form. That suits the compact European character of the Kadett and keeps the look understated, which is often appropriate on German economy and sporting small cars of the mid-1960s. There is no whitewall sidewall treatment in the 155R13 products covered here.

For buyers focused on appearance, blackwall tires usually look most natural on a 1967 Opel unless a particular market-specific restoration standard says otherwise. They also avoid giving the car an Americanized look that can feel out of place on a small Opel. If show authenticity matters, compare your car against period photos and marque-club guidance before settling on the final presentation.

Michelin and Dunlop both make 155R13 tires for 1967 Opel vehicles. Michelin offers the XAS family in this size, while Dunlop offers the SP Sport Aquajet. Both are radial blackwall tires, and both fit the Kadett’s 13-inch wheel diameter requirement.

That gives a 1967 Opel owner two strong period-appropriate European brand directions rather than forcing a generic modern replacement. The choice often comes down to the kind of driving feel and visual character you want from the tread and sidewall presentation, along with any preference for a brand that connects closely to the era. Once you narrow the brand, confirm the exact sidewall marking before final selection.

Michelin XAS and Dunlop SP Sport Aquajet are both 155R13 radial blackwall tires for 1967 Opel vehicles, and both are associated with H-rated sizing. The Michelin version is marked 155HR13 78H TL and carries a stated rim width range of 4.00 to 5.50 inches. The Dunlop version is marked 155R13 78H and carries a stated maximum load capacity of 937 pounds.

In practical terms, both keep you in the correct size family for a Kadett, but the sidewall markings and supporting specs are not identical. Buyers comparing them should look beyond brand name alone and verify the exact tube notation, wheel compatibility details, and the kind of period driving character they want from the car. That approach is more useful than assuming every 155R13 radial is interchangeable in every detail.

For 1967 Opel vehicles using 155R13 tires, the wheel diameter is 13 inches. In the available specifications for this size, one 155R13 product is approved for rim widths from 4.00 to 5.50 inches. That range is a useful benchmark when checking whether a Kadett still wears wheels close to original proportions.

Before mounting tires, verify the actual wheel width on the car rather than assuming every 13-inch wheel is suitable. Older imported cars are often changed over to later steel wheels or aftermarket alloys, and wheel width can affect sidewall shape and steering feel even when the tire size itself is correct. Matching the tire to the wheel is just as important as matching the tire to the car.

Tube status should be checked on the exact 155R13 tire you choose for a 1967 Opel. One available 155R13 radial is explicitly marked TL, which indicates tubeless construction, while another uses a size marking without a tube designation in the size string. That means tube fitment should be confirmed at the product level rather than assumed across the whole size.

The wheel itself also matters, especially on a vintage car that may still have older rims or refinished wheels with varying bead-seat condition. Even when a tire is tubeless by design, a specialist may recommend a different setup depending on the wheel and the car’s intended use. If originality and reliability are both priorities, confirm tire marking and wheel condition together before installation.

A 1967 Opel should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment. Tires hold up best when they are kept clean, properly inflated, and not parked for long periods on damp ground. Radials generally resist long-term flat spotting better than older bias-ply designs, but they still benefit from regular attention during storage.

If the car will sit for months at a time, roll it periodically so one section of the tread is not carrying the load continuously, or support the vehicle appropriately to reduce static stress. That is especially worthwhile on a light vintage compact like the Kadett, where suspension bushings and wheel bearings also appreciate thoughtful storage habits. Good storage protects both the tire and the way the car drives when it comes back out.

Tires on a 1967 Opel should be judged more by age and condition than by mileage. For collector vehicles, many owners begin annual age-focused evaluation once a tire reaches about five to seven years old, and around ten years is a common point for serious replacement consideration even if tread depth still looks good. The DOT date code, physical condition, and storage history matter more than odometer use on a low-mileage Kadett.

That principle is especially important on older hobby cars because they often accumulate very little wear while the rubber still hardens with time. A tire can look presentable and still lose flexibility, wet-road confidence, or structural margin. If the car has recently changed hands and the tire age is unclear, checking the date code is one of the first maintenance steps worth taking.

Tires on a 1967 Opel should be inspected before every drive, with a more deliberate check before any longer outing. Look for sidewall cracking, tread separation, bulges, cuts, uneven wear, and pressure loss, and make sure the spare is in comparable condition if you expect to rely on it. Any tire with questionable age, visible damage, or chronic air loss deserves attention before the car goes back on the road.

A quick walkaround catches problems early, but a hands-on inspection matters too because a lightly used collector car can hide age-related deterioration. Check valve stems as part of the routine, and pay extra attention after the car has sat through a long storage cycle or a major weather change. On a compact 1967 Opel, healthy tires make a noticeable difference in steering response and overall road manners.

A 1967 Opel Kadett would have been associated with narrow European-size tires on 13-inch wheels, and radial construction was already an important part of the European passenger-car market by that period. The correct modern replacement direction here is the 155R13 size family. Original-equipment brand could vary by market, plant supply, and destination, so the safest authenticity baseline is correct size, correct general construction type, and an appropriate sidewall appearance.

Owners pursuing a precise restoration should compare surviving factory literature, unrestored reference cars, and Opel marque-club resources before making the final call on exact presentation. That is especially worthwhile on imported cars, where North American delivery details did not always mirror domestic European-market practice exactly. Even when the size is straightforward, event-level authenticity can turn on smaller visual details.

Yes, correct tire fitment matters when showing a 1967 Opel because judges and knowledgeable enthusiasts often notice size, construction type, and sidewall appearance quickly. A 155R13 blackwall radial suits the car’s compact European identity far better than an oversized or stylistically mismatched substitute. On a well-restored Kadett, tire choice has a real effect on how authentic the whole car appears.

The standard for what counts as correct can vary with the event. Some shows reward a broadly era-appropriate presentation, while stricter judging may place more emphasis on exact sidewall style and market-correct details. If your Opel is being prepared for marque judging rather than informal display, verify expectations with the organizing club so the tire choice supports the rest of the restoration.

For a 1967 Opel, Michelin XAS and Dunlop SP Sport Aquajet both keep the car in the correct 155R13 radial blackwall category, but they are not identical in how they are marked or specified. The Michelin carries a 155HR13 78H TL marking and a stated 4.00 to 5.50 inch rim width range, while the Dunlop uses a 155R13 78H marking and carries a stated 937-pound maximum load figure. Both align with the Kadett’s size and 13-inch rim requirement.

From an authenticity perspective, either can suit a period-minded Opel better than a modern generic substitute in the wrong size or profile. The more exact decision comes down to the sidewall marking style you prefer, the wheel dimensions on your car, and how closely you want the finished look to echo period European tire practice. Small details matter more on a compact car because the tires are visually prominent.

1967 Opel tires in the available 155R13 fitment include H-rated products, which corresponds to a 130 mph speed ceiling for the tire itself. That is comfortably above normal U.S. highway use, assuming the tires are in good condition and properly matched to the wheels. On a vintage Kadett, the larger real-world limit is often the age of the tire and the overall condition of the car’s brakes, suspension, steering, and cooling system rather than the speed symbol alone.

Highway safety starts with condition, inflation, balance, and a sound chassis, not just the printed size. A freshly restored or well-maintained Opel can be enjoyable on longer roads, but an older compact should still be driven with respect for its era and design. If the car feels nervous, wanders, or reacts sharply to grooves, inspect alignment and wheel condition before blaming the tire size itself.

Inflation pressure for 1967 Opel tires should be set with two references in mind: the vehicle maker’s original recommendation for the Kadett and the tire maker’s maximum pressure marking for the specific 155R13 tire. One available 155R13 option also carries a 937-pound maximum load figure, which helps characterize the tire but does not replace the car’s recommended running pressure. Pressure should never be copied from an unrelated size or a different vehicle simply because the wheel diameter matches.

For a collector Opel, proper pressure affects steering feel, ride quality, and tread wear more noticeably than many owners expect. Too much pressure can make a light car feel skittish, while too little can dull response and overwork the sidewalls. Start with the car’s own specification, compare it with the tire maker’s sidewall information, and fine-tune only within safe limits after the basics are verified.

Before a longer drive in a 1967 Opel, inspect all four tires and the spare for cracking, cuts, bulges, irregular wear, and correct cold inflation pressure. Make sure the valve stems are sound and that each tire is holding air consistently. Since the car uses a compact 155R13 fitment, any visible sidewall damage or age-related hardening deserves attention before the trip begins.

The tire check should be part of a broader pre-drive routine that also covers wheel fasteners, brakes, steering, fluids, lights, and cooling system condition. Older Opels are rewarding road cars when sorted properly, but long-distance confidence comes from treating the whole car as a system. A careful inspection at home is far easier than troubleshooting a preventable issue on the shoulder.
