1971 Fiat 124 Tires

A 1971 Fiat 124 can use 155R13, 560-13, 165R13, or 600-13, depending on the exact sub-model. The Special Sedan T.C. uses 155R13 radial or 560-13 bias-ply, the Special Wagons T.C. uses 165R13 radial or 600-13 bias-ply, and the Sport Coupe and Sport Spider use 165R13 radial tires.

That means the first step is confirming whether the car is a sedan, wagon, coupe, or spider before focusing on brands or sidewall style. Since the lineup includes both radial and bias-ply construction, it also helps to verify whether the car still carries its original-style wheel and tire format or has been changed over time.

The tire sizes used on the 1971 Fiat 124 are all built around a 13-inch rim diameter. That applies across the radial sizes 155R13 and 165R13 as well as the bias-ply sizes 560-13 and 600-13, so the wheel diameter itself remains consistent even though tire construction and width vary.

Rim diameter is only part of the fitment picture, especially on an older car that may have seen wheel changes over the years. Wheel width should also be checked against the tire being considered, because the available products span different rim-width ranges depending on whether the tire is a narrow bias-ply whitewall or a wider European-style radial.

The 1971 Fiat 124 covers several distinct sub-models, and they do not all share the same tire setup. The sedan and wagon can appear with either radial or bias-ply fitments in different widths, while the Sport Coupe and Sport Spider use 165R13 radial tires as their primary fitment.

That variation matters because a tire search for one 124 can point to the wrong size if the exact version is not identified first. Checking the sub-model, current wheel width, and whether the car is still on a period-style bias-ply setup or a radial setup will keep the selection process much more accurate.

560-13 is a bias-ply tire size on the 1971 Fiat 124, used on the Special Sedan T.C. as a primary fitment. It is part of the older numeric sizing system, and the available 560-13 products are traditional bias-ply tires rather than radials.

That makes 560-13 the right starting point for owners who want to preserve a period-style bias-ply appearance, especially with whitewall sidewall options. Buyers considering a move away from bias-ply should compare one of the stated radial equivalents carefully and confirm wheel width, overall dimensions, and clearance before making the change.

For a 560-13 bias-ply tire, the radial equivalents are 155R13, P155/75R13, and P155/70R13. For a 600-13 bias-ply tire, the radial equivalents are 165R13, P165/75R13, and P175/70R13. These equivalents cover an 80-series metric radial option plus 75-series and 70-series P-metric alternatives.

The useful distinction is that the alternatives vary by sizing convention and profile family rather than all representing the same presentation. A 4 to 5 inch recommended rim-width range is associated with those equivalent comparisons, so the wheel width, tire dimensions, and available clearance on the car should all be reviewed before treating any radial equivalent as a suitable alternative.

That depends on the exact 1971 Fiat 124 sub-model and the result you want from the car. Some 124 versions use radial sizes such as 155R13 or 165R13, while others also have bias-ply fitments such as 560-13 or 600-13. Both constructions are relevant within this model-year lineup, but they are tied to specific applications.

Bias-ply tires make the most sense when a traditional appearance is the priority, especially with whitewall styling on the sedan or wagon applications. Radials are the natural focus for the coupe, spider, and radial-equipped sedan or wagon setups, but any change from one construction type to another should include a check of wheel width, clearance, and the car's present configuration.

Start with the exact sub-model, because the 1971 Fiat 124 does not use one universal tire size. The next decision is construction type, since some applications are bias-ply and others are radial. Once those two points are clear, compare the available products by wheel-width compatibility, load capacity where stated, series, and sidewall treatment.

A Special Sedan T.C. or Special Wagons T.C. owner may be balancing a traditional whitewall bias-ply look against a radial alternative, while Sport Coupe and Sport Spider owners are choosing among blackwall radial options. The best approach is to match the tire to the car's actual wheel setup, intended road use, and visual goals rather than selecting by size name alone.

The available sidewall styles for 1971 Fiat 124 tires include blackwall, narrow whitewall, and wide whitewall depending on the size and construction. The radial 155R13 and 165R13 options are blackwall tires, while the 560-13 and 600-13 bias-ply options are offered with narrow whitewall or wide whitewall treatments.

That split makes sidewall style part of the overall construction decision, not just a cosmetic afterthought. A buyer aiming for a more European road-car look will usually focus on the blackwall radial selections, while someone restoring a sedan or wagon with a more traditional presentation may prefer one of the whitewall bias-ply options in the correct primary size.

The 1971 Fiat 124 has available tire choices from Michelin, Dunlop, BFGoodrich, and Firestone. Michelin and Dunlop cover the radial side in 155R13 and 165R13 blackwall sizes, while BFGoodrich and Firestone appear in the 560-13 and 600-13 bias-ply selections with whitewall styling.

Brand should be considered alongside size, construction, and tire series rather than treated as the first decision. For this Fiat, a radial shopper may be comparing Michelin XAS-family and Dunlop SP Sport Aquajet options, while a bias-ply shopper is really deciding between whitewall presentations and wheel-width compatibility within the correct 13-inch vintage size.

A period-style choice for a 1971 Fiat 124 starts with the size and construction used by the exact sub-model. For the Special Sedan T.C. and Special Wagons T.C., that may mean staying with 560-13 or 600-13 bias-ply tires if the goal is a more traditional appearance. For the Sport Coupe and Sport Spider, the period-style direction centers on 165R13 blackwall radial tires.

Appearance should follow fitment, not replace it. Sedans and wagons can lean more heavily into whitewall bias-ply presentation, while coupe and spider owners will usually be looking for an authentic-feeling European radial look. If exact originality matters beyond the broad period style, vehicle-specific historical references and marque expertise remain the right final check.

Tire construction changes the visual character of a restored 1971 Fiat 124 more than many buyers expect. The bias-ply options in 560-13 and 600-13 are offered with narrow or wide whitewall styling, which gives the sedan and wagon a distinctly traditional presentation. The radial options in 155R13 and 165R13 come as blackwalls and create a more European touring look.

That visual difference is often just as important as the size itself on a restoration-oriented car. A buyer should choose the construction that matches both the sub-model and the finished look of the vehicle, while also making sure the wheel width and current setup still support the intended tire instead of assuming any 13-inch option will present the same way.

Yes, modifications can affect tire fitment on a 1971 Fiat 124 even when the tire size itself is correct for the sub-model. Aftermarket wheels, changes in wheel width, suspension alterations, lowering, or bodywork changes can all alter the way a 13-inch tire sits and clears the fenders, steering components, or suspension.

That is especially important on a car with both bias-ply and radial fitment paths, since the shape and wheel-width requirements may differ by tire type. A modified 124 should be checked for wheel diameter, wheel width, and full steering and suspension clearance before settling on 155R13, 560-13, 165R13, or 600-13 for regular road use.

Before driving a 1971 Fiat 124 on new tires, inspect the wheels for correct diameter and condition, make sure the tires seat properly, and confirm there is no interference at full steering lock or through suspension travel. Tire pressure, valve stems, and any signs of air loss should also be checked before the first meaningful road use.

An older Fiat may also have age-related issues outside the tire itself, so a quick review of alignment condition, suspension wear, and brake function is worthwhile before a longer drive. It also helps to recheck the tires after the first few miles for clearance marks, pressure stability, and any settling that may show up once the car is back in motion.

Tires on a collector 1971 Fiat 124 should be inspected regularly for cracking, bulges, cuts, uneven wear, and slow air loss, even if the car is driven only occasionally. Pressure should be kept consistent, and the tires should be stored away from prolonged sunlight, moisture, and ozone sources when the car spends long periods parked.

Low annual mileage can hide tire aging, so appearance alone is not enough on a vintage Fiat. It is smart to review the condition of the sidewalls and tread before every drive, especially on bias-ply whitewall tires that may spend a lot of time on display. Occasional movement and basic wheel and suspension checks also help prevent storage-related flat spotting and fitment surprises.
