1966 Saab 750 & 850 GT Tires

The 1966 Saab 750 & 850 GT uses a 155R15 radial tire. This is a classic Euro-metric radial size designed for a 15-inch wheel, and it is the primary fitment for this application.

That makes the first step fairly simple, since the main fitment question is not choosing between multiple primary sizes. The more important checks are whether the car still has the correct 15-inch wheels, whether wheel width falls within the tire’s usable range, and whether any past wheel or suspension changes could affect clearance or overall suitability.

The 1966 Saab 750 & 850 GT uses a 15-inch rim with its 155R15 tire size. Product options in this size commonly pair with relatively narrow wheel widths, including ranges such as 4.00 to 5.50 inches depending on the tire series.

Rim diameter is the non-negotiable starting point, because a 155R15 is built for a 15-inch wheel. Wheel width matters too, especially on a narrower European fitment like this one, so it is worth measuring the actual wheels on the car before choosing among the available radial options.

Yes. The 1966 Saab 750 & 850 GT Basse uses the same 155R15 radial tire size. That keeps sub-model fitment straightforward within this covered application.

Because the size stays the same, the buying decision shifts toward product details rather than sub-model differences. A Basse owner can focus on matching the tire to the actual wheel width, selecting the preferred radial series, and choosing a blackwall option that suits either a driver-quality car or a more restoration-oriented presentation.

Start with the fundamentals: correct 155R15 sizing, radial construction, and compatibility with a 15-inch wheel. From there, compare rim-width range, load-related specifications where stated, tire series, and whether the car is meant for occasional fair-weather use, broader road use, or a more period-style presentation.

This size offers several distinct radial choices, so the decision is less about fitment breadth and more about matching the tire to the car’s setup and purpose. A narrow original-style wheel may steer you toward certain series, while a regularly driven car may lead you to compare load figures, seasonal intent, and overall tire character more closely.

Tires for the 1966 Saab 750 & 850 GT are available from Firestone, Michelin, Avon, and Vredestein in the 155R15 size family. Those brands cover several radial series, including Firestone F560 Radial, Michelin X, Michelin XAS, Michelin XAS-FF, Avon CR6ZZ, Vredestein Snow Classic, and Vredestein Sprint Classic.

Brand choice should be part of a broader comparison rather than the only decision point. It helps to look at each tire’s intended character, wheel-width compatibility, and specification details, then weigh that against how the Saab will actually be used and how closely you want the finished look to reflect a traditional European blackwall presentation.

The 1966 Saab 750 & 850 GT has several 155R15-series choices, including Firestone F560 Radial, Michelin X, Michelin XAS, Michelin XAS-FF, Avon CR6ZZ, Vredestein Snow Classic, and Vredestein Sprint Classic. All of them stay within a blackwall radial presentation suited to this narrow 15-inch fitment.

Series choice matters because it helps define the character of the tire even when the size remains the same. Some buyers will prioritize a traditional appearance, while others may compare wheel-width range, stated load information, or seasonal intent more closely before settling on the tire that best matches the car’s setup.

A period-style starting point for a 1966 Saab 750 & 850 GT is staying with the proper 155R15 radial size and a blackwall presentation. That preserves the narrow European profile that suits the car visually and keeps the overall tire choice aligned with its mid-1960s character.

From there, the decision comes down to how the car will be judged and used. A driver-focused restoration may emphasize practical radial options within the correct size, while a more authenticity-minded project may call for closer comparison of tire series and contemporary Saab references, marque-club guidance, or period photography before making the final selection.

Yes, correct tire fitment matters a great deal on a 1966 Saab 750 & 850 GT restoration. A small European car like this depends on proper tire proportions, and moving away from the correct 155R15 size can quickly change the car’s stance, visual balance, and overall presentation.

Fitment also affects the restoration process beyond appearance alone. The right size helps maintain sensible wheel compatibility and keeps the tire choice in scale with the body and wheel openings, while an off-size selection can introduce unnecessary clearance questions or alter the finished look in ways that distract from the car’s original character.

Yes. Modifications can affect tire fitment on a 1966 Saab 750 & 850 GT even when the intended tire size remains 155R15. Aftermarket wheels, changes in wheel width, suspension work, ride-height changes, or body repairs around the wheel openings can all alter how much room the tire has.

A modified car should be checked as an actual package rather than by size alone. Measure wheel diameter and width, inspect inner and outer clearance at full steering lock, and confirm that nothing rubs under suspension movement. That matters even more on a compact vintage Saab, where small dimensional changes can have an outsized effect.

Before driving a 1966 Saab 750 & 850 GT on new tires, inspect the wheels for damage or corrosion, confirm the 15-inch wheel size, and make sure the selected 155R15 matches the wheel-width requirement. It is also wise to check valve stems, mounting condition, and overall tire pressure before the first road test.

The rest of the car deserves attention too, especially on a collector vehicle that may have spent long periods parked. Look over steering and suspension components, verify that the tires clear through a full turn of the front wheels, and watch for any early signs of rubbing, air loss, vibration, or uneven contact once the car is moving.

155R15 tires on a collector 1966 Saab 750 & 850 GT should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even when mileage stays low, aging still matters, so sidewall cracking, tread hardening, cuts, bulges, and slow air loss should be checked routinely.

A lightly used Saab benefits from being stored away from prolonged sunlight, moisture, and ozone-producing equipment, and from being moved periodically so the tires do not sit in one position for extended stretches. Before any longer drive, inspect tread and sidewalls again and confirm that the tires still feel stable and properly seated on the wheels.
