1974 Mazda RX-2 Tires

The 1974 Mazda RX-2 uses two primary tire sizes: 165R13 in radial construction and 600-13 in bias-ply construction. Both are valid fitments for this model and both use a 13-inch rim, so the main distinction is not wheel diameter but tire construction and sizing format.

That means the first step is deciding whether the car is staying with a bias-ply setup or moving with a radial fitment. After that, check the actual wheel width on the car, especially if the RX-2 has been restored or modified, because construction changes and equivalent sizing choices can affect how the tire works with the wheel and surrounding clearances.

The 1974 Mazda RX-2 uses a 13-inch rim with both of its primary tire sizes, 165R13 and 600-13. That shared rim diameter makes the fitment easier to understand, because the choice between those two sizes centers on radial versus bias-ply construction rather than a change in wheel diameter.

Rim diameter is only part of the fitment picture, though. Wheel width still matters, particularly if the car has aftermarket wheels or if a radial equivalent is being considered in place of the 600-13 bias-ply size. Verifying the actual wheel dimensions on the car helps avoid problems with tire shape, sidewall behavior, or clearance around suspension and fenders.

The 1974 Mazda RX-2 Base can use the same two primary sizes used on the model overall: 165R13 radial and 600-13 bias-ply. There is no separate sub-model-only tire size here, so the Base follows the same core fitment pattern seen across the covered RX-2 listing.

That makes the decision more about tire type and appearance than about trimming down a long fitment list. A Base owner should still confirm the wheels currently on the car, since many older imports have seen wheel swaps over time. Once the wheel setup is confirmed, the choice becomes period-style bias-ply presentation versus radial construction and the available product styles in that size.

For the 1974 Mazda RX-2, 600-13 is a bias-ply tire size. It uses the older numeric sizing format common to many vintage applications, and it represents the traditional-construction option alongside the car’s 165R13 radial fitment.

That matters because bias-ply and radial tires differ not just in construction but also in how they present visually and how they pair with wheel width. A buyer choosing 600-13 is usually leaning toward a more vintage tire profile and period-style appearance. Before changing from one construction type to the other, check wheel width, tire dimensions, and the car’s current ride-height and clearance situation.

Radial equivalents for 600-13 include 165R13 as an 80-series metric radial, P165/75R13 as a P-metric 75-series radial, and P175/70R13 as a P-metric 70-series radial. Those three options give the 1974 Mazda RX-2 owner several ways to compare a radial alternative to the original numeric bias-ply size.

Each equivalent uses the same general 13-inch wheel diameter approach, but the sizing conventions and profile families are different. A recommended rim-width range of 4 to 5 inches is part of the equivalency guidance, and that should be checked against the actual wheels on the car. Clearance around steering, suspension, and bodywork should also be reviewed before treating any equivalent as a usable alternative.

The 1974 Mazda RX-2 supports both approaches, with 600-13 as the bias-ply fitment and 165R13 as the radial fitment. Choosing between them usually comes down to how the car is being presented and used, since bias-ply keeps a more traditional vintage look while radial sizing gives access to period-style import radial offerings.

A restoration-oriented owner may prefer the visual character of the bias-ply option, especially with whitewall choices available in 600-13. A driver focused on maintaining a radial setup may look instead at 165R13 or the radial equivalents related to 600-13. Either way, the current wheel width, suspension condition, and available clearance deserve a close look before making the switch.

Start with the correct size and construction for the setup you want to keep. The 1974 Mazda RX-2 uses 165R13 in radial form and 600-13 in bias-ply form, both on 13-inch rims, so the real comparison is between radial versus bias-ply character, available sidewall style, and the look you want the car to carry.

The next layer is wheel compatibility and product detail. Radial products in 165R13 are offered in blackwall form, while 600-13 bias-ply choices include whitewall treatments. Rim-width range, load figures where shown, and even tire weight can matter when narrowing the field. Matching the tire to the car’s current wheels and intended use is more useful than simply choosing by appearance alone.

The 1974 Mazda RX-2 has both blackwall and whitewall sidewall choices, depending on tire size and construction. The 165R13 radial options are blackwall, while the 600-13 bias-ply options are available with either a wide whitewall or a narrow whitewall.

That split gives the car two distinctly different visual directions. Blackwall radials suit an import-style radial presentation, while the 600-13 whitewall bias-ply options lean more heavily into vintage character. Sidewall choice should also stay connected to the size and construction you plan to run, rather than being treated as an appearance-only decision separate from wheel fitment and the overall stance of the car.

Michelin, Dunlop, and BFGoodrich all offer applicable tires for the 1974 Mazda RX-2. Michelin and Dunlop cover the 165R13 radial side of the fitment, while BFGoodrich supplies the 600-13 bias-ply options through the Silvertown Classic Bias Ply series.

Brand choice here is closely tied to construction, tire series, and sidewall presentation rather than to a simple one-brand answer. Michelin and Dunlop keep the focus on blackwall radial products, while BFGoodrich supports the more traditional 600-13 bias-ply fitment with whitewall styling. The better comparison is how each product aligns with the car’s wheel setup, appearance goals, and intended driving use.

A period-style 1974 Mazda RX-2 can be approached in two different ways because the car uses both 165R13 radial and 600-13 bias-ply fitments. The 600-13 bias-ply option gives the strongest traditional presentation, while 165R13 keeps the car within a vintage import radial format that still feels appropriate to the era.

The better choice depends on the story the car is meant to tell. A more restoration-oriented look may point toward the bias-ply size and its whitewall options, while an owner preserving a later-1970s radial flavor may prefer 165R13 blackwalls. When exact originality matters, checking marque-specific historical references is worthwhile before settling on brand, sidewall treatment, or construction.

Tire construction changes the look of a restored 1974 Mazda RX-2 more than many buyers expect. A 600-13 bias-ply gives the car a distinctly vintage visual character, especially with narrow or wide whitewall styling, while a 165R13 radial presents the car in a cleaner blackwall import-radial format.

That visual difference is one reason construction choice should not be treated as a purely technical decision. On a car with original-style wheels and trim, the tire can strongly influence stance and overall presentation. Keeping the 13-inch wheel diameter correct is only the start; the sidewall style and construction type together shape whether the finished car reads as more traditional or more road-oriented.

Yes, modifications can affect tire fitment on a 1974 Mazda RX-2 even when the tire size itself is correct on paper. Changes such as aftermarket wheels, different wheel widths, altered ride height, suspension work, or body modifications can all change how a 165R13 or 600-13 tire sits and clears the car.

That is especially important on a compact vintage chassis where space can be tighter than expected. A car that has been lowered or fitted with non-stock wheels may need closer attention to steering clearance, fender clearance, and overall tire shape. Checking the actual wheel dimensions and the car’s current setup before choosing a size is the safest path to a usable fitment.

Before driving a 1974 Mazda RX-2 on new tires, inspect the wheels for correct diameter and condition, confirm the tire pressure is set appropriately, and make sure the tires seat properly and clear the car through steering and suspension movement. It is also smart to look at valve stems, wheel hardware, and overall alignment condition.

A brief road-use check after installation can reveal rubbing, vibration, or uneven response that is easier to correct early. On an older car, the condition of shocks, bushings, and steering parts also matters because worn chassis components can make a new tire feel wrong even when the size is appropriate. A careful inspection helps the tire and the car work together properly.

Collector-car tires on a 1974 Mazda RX-2 should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long periods of heat, sunlight, and moisture. That advice applies whether the car is running 165R13 radials or 600-13 bias-ply tires.

Low annual mileage does not eliminate tire aging, so condition deserves as much attention as tread depth. Cars that sit for extended periods benefit from periodic pressure checks and occasional movement to avoid long static loading in one spot. Before any longer drive, give the tires and wheels a close visual inspection and confirm the car still has adequate clearance at normal ride height.
