1968 Chevrolet Corvair Tires

The primary tire size for a 1968 Chevrolet Corvair is 700-13. This is a numeric bias-ply size used on a 13-inch wheel, and it is the central fitment starting point for the model covered here.

That means the first step is usually confirming that the car still has its correct 13-inch wheels and has not been changed to a different wheel package over the years. Once that is settled, the decision becomes whether to keep the original-style 700-13 bias-ply format or compare one of the available radial equivalents while checking wheel width and clearance.

The 1968 Chevrolet Corvair uses a 13-inch rim with its 700-13 tire size. Product fitment in this size also points toward narrow wheel widths, with available 700-13 bias-ply application on 4.00 to 5.00 inch rims.

Rim diameter should be confirmed before ordering tires, especially on a collector car that may have had wheels changed decades ago. Wheel width matters too, particularly if you are considering a radial equivalent, because a radial comparison size may call for a broader acceptable rim-width range than the bias-ply tire originally associated with the car.

Yes. The 1968 Chevrolet Corvair Base uses the same 700-13 bias-ply tire size as the core fitment for this vehicle page. That keeps the fitment picture simple for owners of the Base sub-model.

Even with one shared size, it is still worth checking the actual wheel setup on the car before choosing tires. Older vehicles are often fitted with replacement wheels, and that can affect width compatibility and future radial-equivalent choices even when the nominal rim diameter remains the original 13 inches.

On the 1968 Chevrolet Corvair, 700-13 is a bias-ply tire size. That older numeric format is tied here to traditional bias-ply construction rather than a modern radial designation.

Choosing to stay with bias-ply usually appeals to owners who want an era-appropriate appearance and traditional sizing character. The practical consideration is that a bias-ply tire and a radial equivalent are not the same construction, so any switch should include a check of wheel width, tire dimensions, and how the car is expected to be driven.

Radial equivalents for 700-13 include 185R13, which is an 80-series metric radial, P185/75R13, which is a P-metric 75-series radial, and P205/70R13, which is a P-metric 70-series radial. No bias-look radial equivalent is present for this size.

Those options give owners several ways to compare a modern radial size to the original 700-13 fitment, but they should not be treated as automatic substitutes. The recommended rim-width range for the radial equivalents is 4 to 6 inches, and wheel compatibility, steering clearance, and overall vehicle setup should be checked before converting.

Start by confirming the wheel diameter and width on the car, then compare the intended radial equivalent to the original 700-13 fitment. For this Corvair, the radial-equivalent path includes 185R13, P185/75R13, and P205/70R13, with a recommended rim-width range of 4 to 6 inches.

Clearance should be reviewed at the fenders and through the steering range, especially on an older car that may no longer sit exactly as it did when new. Suspension condition, ride height changes, and any aftermarket wheels can all influence the result, so the conversion decision should be tied to the car’s actual setup rather than the size code alone.

Start with the correct primary size, which is 700-13, and make sure the car still uses a 13-inch wheel in the proper width range for the tire under consideration. On this Corvair, the major choice is between staying with a traditional bias-ply tire or exploring a radial equivalent.

After size and wheel compatibility are confirmed, focus on the kind of ownership experience you want. A bias-ply tire keeps a more traditional presentation, while a radial-equivalent route changes the construction and size format being used. Appearance goals, driving habits, and the actual wheel setup should guide the final selection more than nostalgia alone.

The available 700-13 option for the 1968 Chevrolet Corvair uses a wide whitewall sidewall style. That gives the car a distinctly period-style presentation that suits many restoration-oriented and collector-focused builds.

Sidewall style should be chosen with the car’s finished look in mind rather than treated as a minor detail. Whitewall width has a strong visual effect on a compact 1960s Chevrolet, so owners often decide on sidewall appearance alongside construction choice, especially when weighing a traditional bias-ply tire against a more modern radial-equivalent alternative.

Firestone offers a 700-13 tire for the 1968 Chevrolet Corvair in the Firestone Classic Bias Ply series. That pairing gives owners a known period-style brand presentation in the vehicle’s primary bias-ply size.

Brand is only one part of the decision, though it can matter for appearance and how the finished car presents at a glance. The more practical checks are still size, construction, wheel compatibility, and sidewall style, since those factors determine whether the tire supports the way the Corvair is being restored, displayed, and driven.

A 700-13 bias-ply tire is the strongest period-style starting point for a 1968 Chevrolet Corvair because it keeps the original-style size format and construction approach used on the car. The available Firestone Classic Bias Ply option also supports that traditional presentation.

For many restorations, the goal is not just proper dimensions but the right visual character from the tread profile to the sidewall treatment. Exact originality claims should always be confirmed through marque references and vehicle-specific documentation, but staying with the 700-13 bias-ply format is the clearest way to preserve a 1960s-correct overall impression.

Tire construction affects both stance and visual character on a restored 1968 Chevrolet Corvair. A bias-ply 700-13 keeps the older sizing language and traditional look associated with the car’s era, while a radial equivalent introduces a more modern construction and naming format.

That difference matters because the tire is one of the first details noticed on a finished collector vehicle. Owners who want a more authentic late-1960s presentation often stay with bias-ply, while those prioritizing a radial alternative should decide whether the change in appearance is acceptable alongside any dimensional and wheel-compatibility checks required by the conversion.

Yes. Modifications can affect tire fitment on a 1968 Chevrolet Corvair even when the intended tire size is still based on the original 700-13 setup. Wheel changes, suspension work, altered ride height, or body and fender modifications can all change the amount of available space.

That is especially important when comparing radial equivalents, because the size format may change even though the new tire is being considered as an alternative to 700-13. Any Corvair with aftermarket wheels should have its wheel diameter, width, and clearance checked at full steering range before a final tire choice is made.

Before driving a 1968 Chevrolet Corvair on new tires, inspect the wheels for damage, verify lug hardware condition, and make sure the tires are mounted on the correct 13-inch rims with suitable width. Tire pressure should also be set properly, and the car should be checked for obvious suspension or steering wear.

A short initial road test is a smart follow-up, especially on a collector car that may have sat for long periods. Watch for vibration, rubbing, uneven stance, or steering behavior that suggests a fitment or chassis issue. New tires can only perform as intended when the surrounding wheel, brake, and suspension components are in sound condition.

700-13 tires on a collector 1968 Chevrolet Corvair should be inspected regularly for cracking, cuts, bulges, uneven tread wear, and signs of air loss. Pressure should be checked routinely, and the tires should not be overlooked simply because the car is driven only occasionally.

Storage conditions matter just as much on a low-use Corvair. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve tire condition over time. Seasonal inspection is a good habit, and any tire that shows age-related deterioration should be evaluated before the car is returned to regular road use.
