This application uses an 8.45-15 bias-ply tire on a 15-inch rim. The key decision is usually whether to stay with a traditional period-style bias-ply presentation and then choose among the available tread and sidewall treatments within that size. Careful selection starts with preserving the proper look while confirming the actual wheel setup on the car.
Which Tire Size Is Right for The 1966 Chrysler Disc. Brake Equipped Models
The 1966 Chrysler Disc. Brake Equipped Models use one primary tire size: 8.45-15. That size is a bias-ply fitment for a 15-inch rim, and the covered Base application follows that same sizing pattern. With the size already established, the real choice becomes finding the right period-style tire within 8.45-15 and making sure the wheel and overall vehicle setup still match the original fitment approach.
An 8.45-15 size uses a numeric bias-ply format in which 8.45 refers to the nominal section width in inches and 15 identifies the wheel diameter. For a 1966 Chrysler Disc. Brake Equipped Models application, that means a traditional bias-ply tire matched to a 15-inch rim, consistent with the full-size Chrysler character of the period. This size is best approached as a restoration-oriented fitment where appearance, sidewall presentation, and authentic driving feel matter alongside basic dimensional compatibility. It is the right starting point when the goal is to keep the car visually and mechanically aligned with its original-era tire type.

Frequently Asked Questions
These FAQs focus on 1966 Chrysler Disc. Brake Equipped Models tire size, 15-inch rim fitment, bias-ply construction, restoration-minded selection, and the practical checks worth making before putting a full-size Chrysler back on the road.
Tire Size & Fitment
What tire size fits a 1966 Chrysler Disc. Brake Equipped Models?
The 1966 Chrysler Disc. Brake Equipped Models use an 8.45-15 tire size. This is a numeric bias-ply fitment, so the size reflects a traditional vintage sizing system rather than a modern metric radial designation, and it is intended for a 15-inch wheel.
That makes the first step fairly simple: confirm that the car is part of the disc brake equipped application and that it still has the proper 15-inch wheels. Once size is confirmed, the decision usually shifts to choosing the right period-style tire within 8.45-15 and checking that wheel width, clearance, and overall vehicle setup have not changed through later modifications.
What size rim does a 1966 Chrysler Disc. Brake Equipped Models use?
The primary tire fitment for a 1966 Chrysler Disc. Brake Equipped Models is built around a 15-inch rim. That rim diameter corresponds to the 8.45-15 tire size, where the final number in the size code identifies the wheel diameter the tire is designed to mount on.
Rim diameter should be verified on the actual car before ordering tires, especially on collector vehicles that may have seen wheel changes over time. A 15-inch wheel is required for the proper size match, but diameter alone is not the whole story, so checking wheel width and making sure the tire sits correctly in the wheel opening is still important.
Does the 1966 Chrysler Disc. Brake Equipped Models Base use the same tire size?
Yes. The 1966 Chrysler Disc. Brake Equipped Models Base uses the same 8.45-15 bias-ply tire size as the main application. That means there is no separate primary size to sort through for the covered Base version before moving on to actual tire selection.
Even with shared sizing, it still helps to confirm that the car remains in the disc brake equipped category and retains the correct wheel setup. That keeps the buying process focused on the real decision points, such as period-style appearance, sidewall preference, and overall compatibility with the wheel and suspension condition of the individual vehicle.
Choosing the Right Tire
What should I consider when choosing a 8.45-15 tire for a 1966 Chrysler Disc. Brake Equipped Models?
Start with the confirmed fitment: 8.45-15 on a 15-inch wheel in bias-ply construction. For a 1966 Chrysler Disc. Brake Equipped Models, that size supports a traditional vintage look and driving character, so the main considerations usually center on maintaining the right period-style presentation rather than changing to a different primary size.
After size is established, compare the tire's visual character and how well it suits the car's restoration goals and intended use. A car built for show-focused authenticity may call for a different presentation than one driven regularly, and either way the actual wheel dimensions, suspension condition, and tire clearance should be checked before settling on a final choice.
How do I choose between the available 8.45-15 tires for a 1966 Chrysler Disc. Brake Equipped Models?
Choosing between 8.45-15 tires for a 1966 Chrysler Disc. Brake Equipped Models usually comes down to how closely the tire's appearance matches the car's intended finish and how the tire suits the way the car will be used. Since the primary size and construction are already established, visual style becomes a major part of the decision.
A restoration-oriented car may benefit from a tire that preserves a strong period presence, while a driver-quality car may place equal weight on practicality and overall condition of the wheel-and-tire package. Keeping the correct size is only part of the process, so it is wise to verify wheel dimensions and inspect for any body or suspension changes that could affect clearance.
What rim-fitment details matter when choosing tires for a 1966 Chrysler Disc. Brake Equipped Models?
The most important rim-fitment detail is the 15-inch wheel diameter required by the 8.45-15 tire size. Beyond diameter, the wheel itself needs to be suitable for a vintage bias-ply application, since an older full-size Chrysler depends on the tire and wheel working together to maintain proper stance and fitment.
A car that still has its original-style wheels presents a different situation than one that has been updated over the years. Measuring wheel width, confirming the tire seats properly, and checking clearance at the fenders and steering components all help prevent surprises, especially on a large collector car where visual proportions matter almost as much as basic compatibility.
Restoration & Appearance
Which tire should I choose for a period-style 1966 Chrysler Disc. Brake Equipped Models?

From there, the best choice depends on how authentic or presentation-focused the finished car needs to be. A highly detailed restoration may call for closer attention to sidewall style and overall profile, while a casual show-and-drive car may allow more flexibility. When exact originality matters, marque references and vehicle-specific historical documentation remain important before finalizing the tire selection.
Does correct tire fitment matter for a 1966 Chrysler Disc. Brake Equipped Models restoration?
Yes, correct tire fitment matters significantly on a 1966 Chrysler Disc. Brake Equipped Models restoration.
