1963 Saab 750 & 850 GT Tires

The 1963 Saab 750 & 850 GT uses a 155R15 tire size. This is a Euro-metric radial format with a 155-millimeter nominal section width and a 15-inch rim diameter, making it a tall, narrow radial size that suits the car's period European fitment style.

Since there is one primary size, the real choice is not between multiple fitments but between the available 155R15 tire options. Check the actual wheel width on the car, especially if the wheels have ever been changed, and compare the approved rim-width range of the tire you are considering before making a final selection.

The primary tire fitment for the 1963 Saab 750 & 850 GT is built around a 15-inch rim. That rim diameter matches the 155R15 tire size, and the available products in this fitment are all intended for 15-inch wheels.

Rim diameter is only part of the fitment picture, so it also helps to confirm wheel width before choosing among available tires. Several 155R15 options are approved for widths in the 4.00 to 5.50 inch range, while some are narrower, which matters if the car has replacement or aftermarket wheels.

Yes. The 1963 Saab 750 & 850 GT Base uses the same 155R15 radial tire size as the covered model fitment. That keeps the size question simple and allows the focus to shift toward choosing the right tire series, brand, and wheel-width compatibility within that single size.

Even with shared sizing, it is still smart to inspect the actual wheel setup on the car before ordering tires. Vintage Saabs are often maintained over decades, and a wheel change can alter width even when the rim diameter stays at 15 inches, which can affect which 155R15 products are the best match.

Start with the correct size, which is 155R15, then compare the construction and character of the available radial options. For this Saab, choices include classic blackwall tires from Firestone, Michelin, Avon, and Vredestein, with different series aimed at traditional road use, vintage performance flavor, or specialty seasonal driving.

Wheel width is one of the most useful comparison points because approved ranges vary slightly between products. It also helps to think about how the car will be used: regular fair-weather drives, restoration display, or mixed seasonal use can all point toward a different tire series even when the size stays the same.

The 1963 Saab 750 & 850 GT has 155R15 tire options from Firestone, Michelin, Avon, and Vredestein. That gives buyers a solid spread of classic European-style radial choices rather than a single-brand fitment, with several recognizable series available in the correct size.

Brand choice should be weighed alongside the specific tire series, approved rim width, and how you want the car to look and drive. A restoration-minded owner may prefer one type of classic blackwall presentation, while a frequent road user may focus more on the exact series and fitment details within the same size.

Available 155R15 tire series for the 1963 Saab 750 & 850 GT include Firestone F560 Radial, Michelin X, Michelin XAS, Michelin XAS-FF, Avon CR6ZZ, Vredestein Snow Classic, and Vredestein Sprint Classic. All are radial tires and all use a blackwall sidewall style in this fitment.

Those series give the buyer meaningful variety even though the size itself stays fixed. The practical next step is comparing which series suits the car's intended use, then checking rim-width approval and any load information that matters for your setup rather than assuming every 155R15 option is interchangeable in every detail.

A period-style approach starts with the correct 155R15 radial size, since that preserves the Saab's tall, narrow European tire profile. Within that size, classic blackwall radial lines such as the Firestone F560 Radial, Michelin X family, and Vredestein Sprint Classic all support a traditional vintage presentation.

The right choice depends on how exact the restoration goal is and how the car will be driven. When originality details matter at a very high level, compare the tire's overall look with marque-specific historical references, then confirm the wheel width and the tire's approved fitment range before settling on a final option.

Yes, correct tire fitment matters because the 155R15 size plays a major role in the car's stance and period character. On a compact 1963 Saab 750 & 850 GT, moving away from the proper tall, narrow radial format can change the visual balance even before any difference in driving feel is considered.

Restoration-minded owners should look beyond size alone and evaluate sidewall appearance, tire series, and wheel compatibility. A blackwall radial in the proper fitment keeps the presentation in the right visual territory, while careful wheel-width confirmation helps avoid a tire choice that looks out of place on the car.

Yes. Even though the standard fitment is 155R15 on a 15-inch rim, modifications can change what works cleanly on the car. Wheel width changes, aftermarket wheels, suspension alterations, or body and fender work can all affect clearance and make one 155R15 tire more suitable than another.

A modified car should be checked at full steering lock and through normal suspension movement before settling on a tire. It is also wise to confirm the wheel's actual width, since approved rim-width ranges vary among available 155R15 products and can matter just as much as diameter on a vintage Saab.

Before road use, inspect tire pressure, bead seating, valve condition, lug torque, and visible clearance around the fenders and suspension. On a collector-era Saab, it also makes sense to check steering movement lock to lock and look for any signs that the tire sits too close to a wheel arch or suspension component.

The rest of the car deserves attention too, especially if it has been parked for long periods. Wheel bearings, brakes, alignment condition, and worn suspension parts can affect how new tires behave, so a careful once-over helps the 155R15 fitment work as intended and reduces surprises on the first longer drive.

Maintain 155R15 tires on a collector 1963 Saab 750 & 850 GT by checking air pressure regularly, inspecting tread and sidewalls for cracking or cuts, and watching for bulges or slow air loss. Cars that see limited mileage still need routine inspections because age and storage conditions can affect tire condition even when tread wear is low.

Storage habits matter on a lightly used vintage Saab. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, and occasional movement can reduce long-term flat spotting. Before a longer outing, inspect all four tires closely rather than assuming low annual mileage means they are road-ready.
