1958 Toyota Toyopet Tires

A 1958 Toyota Toyopet can use 155R14, 560-14, 185R15, or 640-15, depending on the sub-model. Corona models use the 14-inch group with 155R14 radial or 560-14 bias-ply, while Crown & Deluxe models use the 15-inch group with 185R15 radial or 640-15 bias-ply.

The main step is confirming which Toyopet sub-model is in front of you and whether it still has the correct wheel diameter. Once that is settled, the decision becomes whether to stay with a period-style bias-ply construction or select the radial size used with that same sub-model and wheel group.

The 1958 Toyota Toyopet uses either a 14-inch or 15-inch rim, depending on the sub-model. Corona applications use 14-inch tire sizes, while Crown & Deluxe applications use 15-inch tire sizes, so there is not one universal rim diameter across every 1958 Toyopet covered here.

That difference makes wheel confirmation essential before any tire purchase. A buyer should check the actual wheel diameter on the car, especially if the vehicle has been restored, modified, or stored with mixed parts, because the 14-inch and 15-inch Toyopet fitments use different primary tire size groups.

No. The 1958 Toyota Toyopet does not use one shared tire size across all covered sub-models. The Corona uses 14-inch sizes, 155R14 radial or 560-14 bias-ply, while the Crown & Deluxe uses 15-inch sizes, 185R15 radial or 640-15 bias-ply.

That means sub-model identification is more important than simply knowing the year and make. Even if two cars look similar, the tire decision changes with the wheel diameter and construction style tied to that specific sub-model, so checking both the badge and the actual wheel setup is the safest starting point.

Radial equivalents for the 640-15 bias-ply size include 175R15, P175/75R15, and P185/70R15. Those options represent an 80-series metric radial, a P-metric 75-series radial, and a P-metric 70-series radial, giving Crown & Deluxe owners several radial formats to compare against the original 15-inch bias-ply fitment.

A recommended rim-width range of 5-6 inches applies to that equivalent group, but an equivalent is still only a comparison point until the actual car is checked. Wheel width, overall package dimensions, and steering or fender clearance should be verified before changing from 640-15 to any radial alternative.

The answer depends on the sub-model, wheel diameter, and the type of ownership experience you want. The 1958 Toyota Toyopet has both period-style bias-ply options, 560-14 and 640-15, and radial options, 155R14 and 185R15, tied to its respective 14-inch and 15-inch applications.

Bias-ply tires usually appeal to buyers focused on a traditional presentation, while radial choices often appeal to owners who want a more modern tire format on the same rim diameter. The important step is matching the construction choice to the correct sub-model and wheel size rather than assuming one format belongs on every Toyopet.

Start by confirming the current wheel diameter and making sure the radial size being considered belongs to that Toyopet sub-model. A Corona should stay within its 14-inch fitment group, and a Crown & Deluxe should stay within its 15-inch group, with 640-15 equivalents such as 175R15, P175/75R15, or P185/70R15 considered only for the 15-inch application.

After that, check wheel width, tire-to-fender clearance, and steering clearance on the actual car. Older collector vehicles may also have suspension wear, replacement wheels, or previous modifications, so the conversion should be treated as a full fitment review rather than only a size-code swap.

For a 1958 Toyota Toyopet using 640-15, the first consideration is making sure the car is a Crown & Deluxe with the correct 15-inch wheel setup. Once that is confirmed, the main comparison points are construction style within the bias-ply category, sidewall appearance, brand, tire series, and the rim-width specifications associated with the available products.

That size is offered in blackwall, narrow whitewall, and wide whitewall versions from BFGoodrich, Firestone, Avon, and Excelsior. Choosing among them usually comes down to the visual character you want, how closely you want to keep a period-style presentation, and whether the wheel width on the car matches the tire’s intended range.

Sidewall choices for 1958 Toyota Toyopet tires include blackwall, narrow whitewall, wide whitewall, and redline, depending on the size. The 14-inch 560-14 bias-ply options include blackwall and whitewall styles, the 15-inch 640-15 group adds both narrow and wide whitewalls, and some 185R15 radial options are available with redline treatment.

That variety gives owners room to match the tire’s appearance to the car’s restoration style or personal taste without changing the basic fitment group. The important part is choosing the sidewall style only after the correct size and wheel diameter are confirmed for the Corona or the Crown & Deluxe application.

Tire choices for the 1958 Toyota Toyopet include Michelin, Firestone, BFGoodrich, Avon, Excelsior, Coker Classic, and Universal Vintage Tire. Brand availability depends on size, with 14-inch and 15-inch applications drawing from different product groups and with the broader assortment appearing in the 15-inch Crown & Deluxe fitments.

Brand alone should not drive the decision. Size, wheel diameter, construction type, sidewall presentation, and tire series all matter more for getting the right Toyopet fitment and look, especially because the car uses different tire groups across its sub-models and includes both bias-ply and radial choices.

A period-style 1958 Toyota Toyopet usually starts with the numeric bias-ply size matched to the correct sub-model and wheel diameter. That means 560-14 for the Corona or 640-15 for the Crown & Deluxe, both of which preserve the traditional sizing style associated with the car’s original era.

From there, the appearance choice shifts to blackwall or whitewall treatment depending on the size and the look you want. When exact historical originality matters, checking marque references, period photography, or model-specific restoration guidance is worthwhile before choosing a sidewall style or brand presentation.

Tire construction changes more than ride feel on a restored 1958 Toyota Toyopet; it also changes the visual character of the car. Numeric bias-ply sizes such as 560-14 and 640-15 deliver the older style of sidewall and overall presentation, while 155R14 and 185R15 radials introduce a more modern sizing format.

That distinction matters most on a restoration where the tire is part of the car’s stance and visual balance. A buyer who wants a strongly vintage look will often begin with the bias-ply fitment, while a buyer focused on radial construction should still choose a sidewall treatment that suits the era of the Toyopet.

Yes. Modifications can change tire fitment on a 1958 Toyota Toyopet even when the nominal size seems correct. Aftermarket wheels, altered wheel width, different offset, lowered suspension, replacement springs, or bodywork changes can all affect whether a 14-inch or 15-inch Toyopet tire setup clears the car properly.

A car that has been changed from original condition should be measured rather than assumed to follow stock fitment. Checking wheel diameter, wheel width, steering travel, and fender clearance before mounting new tires is especially important on a Toyopet, because the covered sub-models already split between two different rim diameters.

Before road use, inspect the wheels for damage or mismatch, verify that all four tires are the intended size and construction, and make sure inflation is set appropriately for the tire being used. It is also wise to check for rubbing at full steering lock and to confirm that the car sits evenly on its suspension.

Collector vehicles often reveal other issues only after the tire change is complete. Brake drag, loose steering parts, worn bushings, or poor alignment can affect how the new tires behave, so a short, careful test drive and a follow-up inspection for air loss or fresh contact marks are sensible precautions.

Tires on a collector 1958 Toyota Toyopet should be checked regularly for air pressure, cracking, cuts, bulges, uneven tread wear, and signs of prolonged age even if the car is driven only occasionally. Low-mileage storage does not stop rubber from aging, so visual condition matters just as much as remaining tread depth.

Storage habits also affect tire life. Keeping the Toyopet away from prolonged sunlight, heat, moisture, and ozone sources can help preserve the tires, and moving the car periodically can reduce long stationary loading. Any tire that shows structural deterioration should be evaluated before the car returns to regular road use.
