1970 Saab Tire Fitment Guide

Three tire sizes fit the 1970 Saab range: 155R15, 560-15, and 165R15. The 155R15 radial fits Saab 95 & 96, Saab 97, Saab 99, and Sonett models. The 560-15 bias-ply fits Saab 95 & 96, Saab 97, and Sonett models, while 165R15 radial is specific to the Saab 99. All three sizes mount on 15-inch rims, and rim width ranges vary by size, from 4.00 to 5.50 inches on some 155R15 products, 4.5 to 5.50 inches on 560-15 products, and 4.50 to 6.00 inches on 165R15 products.

That makes model identification the first step before choosing a tire for any 1970 Saab. If you own a 95, 96, 97, or Sonett, you may be choosing between an earlier-style 560-15 bias-ply and a 155R15 radial, while Saab 99 owners should focus on the two radial sizes associated with that model. Once the model is confirmed, compare the tire's approved rim width to the wheel actually on the car.

On a 1970 Saab, 560-15 is a numeric bias-ply tire size. The 5.60 figure is the nominal section width in inches, written without a decimal point after the first digit, and the 15 is the wheel diameter in inches. It is not a radial code, and it belongs to the older numeric sizing system common before metric radials became dominant.

For a 1970 Saab owner, that code usually signals a more traditional restoration path for the Saab 95 & 96, Saab 97, or Sonett rather than the later Saab 99. It also means you should expect the driving feel and visual profile associated with bias-ply construction, not a modern radial response. If originality matters, confirm whether your car's market, restoration goal, and wheel width support 560-15 before making the final choice.

No. Every 1970 Saab model in this group can use 155R15, but the rest of the fitment differs by model. Saab 95 & 96, Saab 97, and Sonett also use 560-15 bias-ply, while Saab 99 adds 165R15 radial instead. The result is a shared baseline size across the make, plus model-specific alternatives that reflect the difference between the earlier compact cars and the newer 99.

That variation matters because a buyer who knows only the year and make can easily end up comparing the wrong size family. Earlier-bodied Saabs often raise the question of bias-ply appearance versus radial behavior, while the Saab 99 points you toward radial-only choices and a wider 165R15 option. If the car has been restored or wheels have been changed over the years, verify both the model and the wheel before ordering.

For Saab 95 & 96, Saab 97, and Sonett models, the choice between 560-15 and 155R15 is mainly a choice between bias-ply and radial construction. The 560-15 keeps the older numeric bias-ply format and traditional sidewall look, while 155R15 is a radial size used across the full 1970 Saab range. Saab 99 owners do not make this particular choice, because 560-15 does not apply to that model.

Owners aiming for an earlier visual presentation often gravitate toward 560-15, especially when whitewall styling is part of the car's finished look. Owners who want a radial fitment that is broadly shared across the 1970 Saab lineup usually start with 155R15 instead. The best path is to match the tire to the car's model, the way the car will be used, and the overall restoration standard you are trying to maintain.

Sidewall style varies quite a bit across 1970 Saab tire sizes. The 155R15 radial options are blackwall only, giving that size a distinctly European appearance. The 560-15 bias-ply options come in narrow whitewall and wide whitewall versions, while 165R15 radial options for the Saab 99 appear in blackwall, narrow whitewall, and wide whitewall styles.

That range gives a 1970 Saab owner more flexibility than a single-size page might suggest. A blackwall radial usually aligns with the understated European character many Saab enthusiasts prefer, while whitewall treatments can support a more period-accessorized presentation depending on the model and restoration goal. If authenticity matters for a judged car, use period photos, factory literature, and Saab club guidance to confirm whether a whitewall style suits your specific car.

Several brands cover 1970 Saab sizes. In 155R15, Firestone and Michelin are available. In 560-15, Firestone and US Royal are available. In 165R15 for the Saab 99, choices include Coker Classic, American Classic, Firestone, and BFGoodrich.

Brand choice often comes down to the size you need first and the sidewall look you want second. Michelin's presence in 155R15 suits the European flavor of a 1970 Saab, while Firestone spans both radial and bias-ply offerings across the range. For Saab 99 owners using 165R15, the broader brand spread also opens up more visual choices, especially if blackwall versus whitewall appearance is part of the decision.

Rim width depends on the tire size chosen for a 1970 Saab. Many 155R15 radial products fit 4.00 to 5.50 inch rims. The 560-15 bias-ply size fits 4.5 inch rims in some cases and also appears with a 4.50 to 5.50 inch approved range. The 165R15 radial size used on the Saab 99 fits 4.50 to 6.00 inch rims.

That is why wheel confirmation matters even though every size here is built for a 15-inch diameter wheel. Two tires may share the same rim diameter but still expect different rim widths for proper section shape and support. Before mounting a new set on any 1970 Saab, compare the wheel actually on the car to the approved range for the exact tire you intend to use rather than assuming all 15-inch Saab wheels are equivalent.

Inner-tube status is straightforward for some 1970 Saab tires and mixed for others. In 155R15, it varies by product: Michelin X is tubeless, Michelin XAS is tube-type, and Michelin XAS-FF is tubeless. The 560-15 products shown here do not carry a tube-type or tubeless marker in the size line, and the 165R15 products also do not use a TT or TL suffix in the same way.

Because tube status can differ even within the same 155R15 size, the sidewall marking on the exact tire matters more than the size alone. Saab owners should also consider wheel design and condition, especially on older restored steel wheels, before deciding whether a tubeless fitment is appropriate. If you are preserving original wheels, have the wheel and valve-stem setup inspected at the same time as the tire selection.

All 1970 Saab tire sizes covered here use a 15-inch rim diameter, so there is basic diameter compatibility across 155R15, 560-15, and 165R15. That said, the approved rim-width range changes by size. A wheel that suits a 155R15 may not automatically be the best match for a 165R15, and a wheel used with 560-15 should still be checked against the specific tire's approved width.

For owners of Saab 95, 96, 97, and Sonett models, that means a radial-versus-bias decision does not automatically require a different wheel diameter, but it can still call for a width check. Saab 99 owners considering 165R15 should be especially mindful of that wider approved range. Original wheels can often remain in service, but the final decision should be made after confirming the wheel dimensions and overall wheel condition.

A stored 1970 Saab should be kept away from direct sunlight, electric motors, ozone-producing equipment, and damp surfaces that hold moisture against the tires. Clean, dry storage helps any collector tire last longer, but construction type matters too. Bias-ply tires such as 560-15 tend to flat-spot more readily during long static storage, while radial sizes such as 155R15 and 165R15 are generally less prone to that temporary shape change.

If a 1970 Saab will sit for extended periods, keep the tires properly inflated and move the car occasionally to change the contact patch. Many owners also use tire cradles or place the car on stands for very long storage intervals, especially when preserving a restored vehicle. A quick warm-up drive can often reduce mild flat-spotting, but preventing it in storage is better than trying to drive it out later.

Tire life on a 1970 Saab is usually judged more by age than by mileage, because collector cars often accumulate miles slowly. A sensible rule is to begin evaluating tires closely once they are around five to seven years old and to treat ten years as a serious replacement consideration regardless of tread depth. The DOT date code on the tire sidewall is the reference point for age, not the date the car was restored.

That matters because a 1970 Saab can look freshly finished and still be riding on tires that have aged out. Sidewall appearance, internal aging, and long-term storage conditions all affect service life, even when tread wear seems minimal. If the car is driven only seasonally, keep a written record of installation dates and inspect the date code during annual maintenance so age does not get overlooked.

Tires on a 1970 Saab should be inspected before every drive and again before any extended outing. Look for cracking, cuts, bulges, uneven wear, embedded debris, and pressure loss. Because some 155R15 products are tube-type and others are tubeless, valve stems and any tube-related hardware deserve the same attention as the casing and tread.

Regular inspection is especially important on a lightly used collector car because tire problems often develop while the car is parked, not while it is accumulating miles. A quick walk-around before departure can catch a soft tire, damaged sidewall, or aging spare before it becomes a roadside issue. Seasonal cars also benefit from a more thorough check at the start of each driving season and after winter storage.

For a 1970 Saab Saab 95 & 96, bias-ply construction remained part of the period landscape, and 560-15 reflects that older sizing system directly. At the same time, 155R15 radial fitment also belongs to the 1970 Saab range and can be correct depending on market, specification, and how the car was delivered. No single original-equipment brand should be assumed without vehicle-specific confirmation.

That means a careful restoration starts with more than the year and model name alone. If your goal is factory-authentic presentation, compare surviving original paperwork, period road tests, and Saab club knowledge against the car you own. Buyers restoring a U.S.-market car versus a European-market car should be especially cautious, because a subtle difference in original specification can change whether a bias-ply or radial fitment is the better historical match.

Yes, correct tire fitment matters on a 1970 Saab if the car will be judged for authenticity. Size, construction type, and sidewall style all affect how convincingly the finished car represents its period. A bias-ply 560-15 and a radial 155R15 can both be appropriate in the broad 1970 Saab universe, but they do not present the same visual or historical impression on the car.

Judges and marque specialists often notice sidewall treatment and tire profile immediately, even before they consider mechanical details. A modern-looking radial or an overly decorative whitewall can stand out on a car restored for strict originality if the model and market did not use that look. Before a serious show, compare your tire choice to period photos and event standards, then use Saab club guidance to settle any close calls.

For a 1970 Saab using 155R15, both the Michelin XAS and Michelin XAS-FF appear as 155HR15 82H radial tires, so both carry an H speed rating with a 130 mph ceiling. Each uses a 15-inch rim diameter and a 4.00 to 5.50 inch rim-width range, and both come in blackwall form. The practical difference here is tube status: Michelin XAS is tube-type, while Michelin XAS-FF is tubeless.

That distinction can matter on a restored Saab where the wheel condition or restoration philosophy favors one setup over the other. If you are keeping original wheels and want to preserve a traditional tube arrangement, the XAS may better suit that plan. If your wheel condition and application support tubeless use, the XAS-FF may align more naturally, but the final call should always be made after inspecting the wheel and confirming the tire's sidewall marking.

Yes, 1970 Saab tires can be suitable for highway driving when they are the correct size, in good condition, and used within their speed and load limits. Among the 155R15 options, Michelin X carries a T rating to 118 mph, while Michelin XAS and XAS-FF carry H ratings to 130 mph. The 560-15 bias-ply choices do not show speed letters in the same way, and the 165R15 products here also do not display speed letters in their size lines.

In real use, a 1970 Saab's age, brakes, suspension condition, steering, and overall mechanical health usually matter as much as the tire's theoretical top-speed rating. Highway safety depends on the whole car working as a system, not on the tire alone. Before regular higher-speed use, make sure the tires are age-appropriate, correctly inflated, and matched to the model, then give the rest of the car the same level of attention.

Inflation pressure on a 1970 Saab should be guided first by the vehicle's factory recommendation and then checked against the tire's own load-and-pressure rating. In these sizes, 155R15 appears with a maximum load of 1045 pounds at 44 psi on one radial product, 560-15 carries 970 pounds at 32 psi, and 165R15 ranges from 1168 pounds at 35 psi to 1170 pounds at 36 psi depending on the product. Those figures are maximum load-pressure pairings, not blanket running pressures for every Saab application.

That distinction matters because a reproduction or replacement tire can have a different rated pressure from the original tire type the car was built around. Start with the owner's manual or factory placard if available, then make sure the chosen operating pressure makes sense within the tire manufacturer's limits for the exact tire on the car. Never transfer a pressure figure from one 1970 Saab size to another simply because both fit 15-inch wheels.

Before a longer drive in a 1970 Saab, inspect each tire for sidewall cracking, tread separation, cuts, bulges, punctures, and uneven wear, then confirm pressures cold. Check valve stems closely, and if your chosen 155R15 setup uses tube-type construction, treat the tube and stem hardware as part of the safety inspection. The spare should also be aired up and examined, not just carried.

A longer trip also deserves a broader mechanical check because tire condition is only one part of road readiness on a 1970 vehicle. Wheel bearings, brakes, suspension joints, alignment, and charging-system health all affect how safely and comfortably the car can use its tires at distance. A few minutes in the garage before departure can prevent both tire trouble and the kind of age-related roadside problem that vintage Saab owners know too well.
