1966 Dodge covered a broad slice of the American market, from compact Dart models to mid-size Coronets and full-size Dodge cars, and that variety is exactly why tire fitment matters at the year-and-make level. Styling, stance, and road manners were closely tied to wheel and tire proportions in this era, especially on Mopar cars where body size and intended use could change the original size choice. Across 1966 Dodge, seven bias-ply sizes appear across three model lines, with some shared between models and others tied to a specific car. Before choosing a tire, confirm your exact model first, then match the correct size and sidewall style to your restoration goals.
Which Tire Size Is Right for Your 1966 Dodge
Seven tire sizes were used across 1966 Dodge vehicles, and they vary by model rather than carrying across the whole range. Every size here is a bias-ply fitment, so the main decision is confirming the correct model and rim diameter first, then choosing the sidewall style that best suits the car. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 1966|Fit(s): Coronet|Construction: Bias Ply|Rim: 14 in
The 775-14 is a numeric bias-ply size, with 7.75 indicating nominal section width and 14 indicating the wheel diameter in inches. This Coronet-specific size is available from US Royal, BFGoodrich, and Firestone in narrow whitewall and redline sidewall styles. It suits a 1966 Dodge Coronet owner who wants the taller, period-correct look and traditional bias-ply character that fits a mid-size Mopar restoration.
Year(s): 1966|Fit(s): Coronet, 1966 Dodge|Construction: Bias Ply|Rim: 14 in
The 825-14 is a numeric bias-ply size, with 8.25 indicating nominal section width and 14 indicating the wheel diameter in inches. BFGoodrich offers this size in blackwall and narrow whitewall versions. Because it is shared by certain Coronet applications and full-size 1966 Dodge cars, this size is the right choice when your car calls for a fuller 14-inch bias-ply fitment and you want to stay within the original-style construction.
Year(s): 1966|Fit(s): Coronet, Dart|Construction: Bias Ply|Rim: 14 in
The 695-14 is a numeric bias-ply size, with 6.95 indicating nominal section width and 14 indicating the wheel diameter in inches. It is available from BFGoodrich and US Royal, with narrow whitewall, blackwall, and dual-redline sidewall styles. Shared by certain Coronet and Dart models, this size is a useful choice for owners seeking an original-style 14-inch bias-ply tire with several appearance options for restoration or period street presentation.
Year(s): 1966|Fit(s): Coronet|Construction: Bias Ply|Rim: 14 in
The 735-14 is a numeric bias-ply size, with 7.35 indicating nominal section width and 14 indicating the wheel diameter in inches. This Coronet-specific size comes from BFGoodrich in blackwall and narrow whitewall styles. It fits buyers who have a 1966 Dodge Coronet that uses this narrower 14-inch fitment and want a clean factory-style appearance in traditional bias-ply construction.
Year(s): 1966|Fit(s): Dart|Construction: Bias Ply|Rim: 13 in
The 650-13 is a numeric bias-ply size, with 6.50 indicating nominal section width and 13 indicating the wheel diameter in inches. This Dart-specific size is available from Coker Classic and US Royal in wide whitewall and narrow whitewall styles. It is a strong match for a 1966 Dodge Dart owner restoring a compact Mopar with original-style 13-inch wheels and a distinctly mid-1960s sidewall look.
Year(s): 1966|Fit(s): Dart|Construction: Bias Ply|Rim: 13 in
The 700-13 is a numeric bias-ply size, with 7.00 indicating nominal section width and 13 indicating the wheel diameter in inches. Firestone offers this Dart-specific size with a wide whitewall sidewall treatment. It is best suited to a 1966 Dodge Dart that originally used a slightly larger 13-inch bias-ply tire and where period appearance matters more than changing to a different wheel diameter.
Year(s): 1966|Fit(s): 1966 Dodge|Construction: Bias Ply|Rim: 14 in
The 855-14 is a numeric bias-ply size, with 8.55 indicating nominal section width and 14 indicating the wheel diameter in inches. BFGoodrich offers this size in narrow whitewall versions. Specific to full-size 1966 Dodge cars, it is the right fit when the car uses the largest 14-inch bias-ply option in this range and the goal is a substantial factory-style stance.
Three model lines are covered for 1966 Dodge, and tire size changes with the model rather than staying the same across the whole make. That means year and make alone are not enough here, especially because Dart applications use both 13-inch and 14-inch sizes while Coronet and full-size Dodge cars stay in the 14-inch range. Select your model below to narrow the correct fitment history and tire choices.
1966 Dodge Coronet
The 1966 Dodge Coronet was Dodge's mid-size entry, positioned between compact transportation and full-size family cars, and it became one of the brand's key platforms during the muscle-car era. Coronet applications here use 14-inch tires throughout, but the exact numeric size varies enough that the specific model and original setup matter before choosing a replacement.
The 1966 Dodge Dart was Dodge's compact offering, known for practical proportions and broad appeal from basic transportation to sportier trims. Dart fitments span both 13-inch and 14-inch wheels, so identifying the exact model and wheel setup is especially important before settling on a tire size.
Full-size 1966 Dodge cars were built to deliver a larger footprint and more substantial road presence than the Dart or Coronet. These applications use 14-inch tires, with size choice centered on the correct larger numeric fitment for the particular car rather than on switching construction type.
Thirty-two products are available across seven tire sizes for 1966 Dodge vehicles. The 775-14 comes in 4 products from US Royal, BFGoodrich, and Firestone with narrow whitewall and redline styles; 825-14 has 3 BFGoodrich bias-ply choices in blackwall and narrow whitewall; 695-14 has 4 from BFGoodrich and US Royal in narrow whitewall, blackwall, and dual-redline; 735-14 has 2 BFGoodrich options in blackwall and narrow whitewall; 650-13 has 4 from Coker Classic and US Royal in wide and narrow whitewall; 700-13 has 1 Firestone wide whitewall; 855-14 has 2 BFGoodrich narrow whitewalls.
These answers focus on the model-by-model size differences across 1966 Dodge, what old-style numeric sizing means, which sidewall treatments are available, and how to care for bias-ply tires on collector cars that may spend long periods parked.
Size Basics & Fitment
What tire sizes fit 1966 Dodge vehicles?
1966 Dodge vehicles use seven bias-ply numeric sizes across three model lines: 775-14, 825-14, 695-14, 735-14, 650-13, 700-13, and 855-14. Coronet applications use 775-14, 825-14, 695-14, and 735-14; Dart applications use 650-13, 700-13, and 695-14; full-size Dodge applications use 825-14 and 855-14. Rim widths vary by size where product guidance exists, from 4.00-5.00 inches on 700-13 up to 5.50-6.00 inches on some 14-inch sizes.
The practical takeaway is that a 1966 Dodge owner needs to identify the exact model before choosing a tire size, because the make spans both 13-inch and 14-inch fitments. Once the size is confirmed, the next step is matching the sidewall style and recommended rim-width range to the car's restoration direction and the wheel actually on the vehicle.
What does 775-14 mean on a 1966 Dodge tire?
On a 1966 Dodge, 775-14 is a numeric bias-ply size. The 7.75 portion refers to the tire's nominal section width in inches, written without a decimal, and the 14 refers to the wheel diameter in inches. For 1966 Dodge applications, this size belongs to the Coronet and mounts on a 14-inch wheel.
That old numeric format differs from later alphanumeric and metric sizing, so reading it correctly helps avoid ordering a tire that looks close but mounts to the wrong wheel. A 775-14 keeps you in an original-style bias-ply construction, which is usually the right direction when the goal is preserving factory-era appearance and proportions on a mid-1960s Dodge.
Do all 1966 Dodge models use the same tire size?
No, 1966 Dodge models do not all use the same tire size. The Dart uses 650-13, 700-13, and 695-14, the Coronet uses 775-14, 825-14, 695-14, and 735-14, and full-size Dodge cars use 825-14 and 855-14. Only 695-14 is shared between Dart and Coronet, and only 825-14 is shared between Coronet and full-size Dodge applications.
That variation means a buyer should not choose a tire on year and make alone. If the car has changed wheels over the years, verify the actual wheel diameter as well as the model, because a compact Dart and a full-size 1966 Dodge can sit on very different original tire sizes even though they came from the same showroom year.
Buying the Right Tire
What sidewall styles are available for 1966 Dodge tires?
1966 Dodge tires are available in several period-style sidewall treatments depending on size. Narrow whitewall appears across most sizes, blackwall is offered in 825-14, 695-14, and 735-14, redline appears in 775-14, dual-redline appears in 695-14, and wide whitewall appears in 650-13 and 700-13. Those visual differences can change the whole character of a mid-1960s Dodge, especially on compact and intermediate cars where wheel opening and body trim make the sidewall more noticeable.
Choosing among them is largely an authenticity and style decision. Wide whitewalls tend to suit more traditional presentations, blackwalls create a plainer factory or understated look, and redline variations fit buyers who want a period performance flavor. The right choice depends on how your particular 1966 Dodge is being restored rather than on any mechanical requirement of the size itself.
What brands make tires for 1966 Dodge vehicles?
1966 Dodge tires are available from BFGoodrich, Firestone, US Royal, and Coker Classic, depending on size. BFGoodrich covers 775-14, 825-14, 695-14, 735-14, and 855-14; Firestone covers 775-14 and 700-13; US Royal covers 775-14, 695-14, and 650-13; and Coker Classic covers 650-13. All of these offerings stay within the bias-ply construction used across this year and make.
Brand choice usually comes after confirming the correct size, because not every brand appears in every fitment. Once the size is settled, the decision often comes down to the sidewall treatment you want and whether a certain series better matches the visual character of your 1966 Dodge, especially for a show-focused restoration.
What is the difference between BFGoodrich and US Royal 695-14 tires for a 1966 Dodge?
For a 1966 Dodge using 695-14, BFGoodrich and US Royal both offer bias-ply tires with the same 1230-pound load capacity at 32 psi and the same 14-inch rim diameter. BFGoodrich brings the widest appearance choice in this size, with narrow whitewall, blackwall, and dual-redline versions, while US Royal appears in narrow whitewall form. Weight runs 19 to 20 pounds for BFGoodrich and 21 pounds for US Royal.
That means the real difference is visual character and series preference rather than a major change in basic fitment. A Dart or Coronet owner choosing 695-14 can stay close to the same load and wheel requirements while selecting the sidewall look that best matches the car's trim, intended presentation, and period personality.
Fitting & Setup
What rim width do 1966 Dodge tires require?
Rim-width guidance for 1966 Dodge tires varies by size. The 650-13 fits 4.50-5.00-inch rims, the 700-13 fits 4.00-5.00-inch rims, the 695-14 and 825-14 fit 5.00-6.00-inch rims, the 735-14 fits 5.00-5.50-inch rims, and the 775-14 and 855-14 fit 5.50-6.00-inch rims on some products. Those ranges are an important part of proper setup because the same wheel diameter does not always mean the same wheel width.
A tire can mount on the right diameter wheel and still be wrong for the rim if the width is outside the recommended range. Before choosing a replacement for a 1966 Dodge, measure the wheel or confirm its original specification so the tire's shape, stance, and contact patch stay within the intended range for that size.
Can the original 1966 Dodge wheels be used with all tire sizes?
Original 1966 Dodge wheels can only be shared among tire sizes when both the wheel diameter and the rim width are appropriate for the tire. Coronet and full-size Dodge applications here are built around 14-inch tires, while Dart applications include both 13-inch and 14-inch sizes. Even among 14-inch tires, rim-width recommendations differ by size, so wheel diameter alone is not enough to confirm interchange.
That matters most on cars that have been swapped between trims, years, or aftermarket wheels over time. A 14-inch Coronet tire will not solve a Dart fitted with original 13-inch wheels, and a wider 14-inch size should still be checked against the actual wheel width before use. Treat the wheel already on the car as something to verify, not assume.
Maintenance, Storage & Longevity
How should I store a 1966 Dodge when the tires are fitted?
A 1966 Dodge should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing sources. Because every fitment here is bias-ply, long periods of sitting can encourage flat-spotting and gradual sidewall aging more readily than many modern radials. Keeping the tires properly inflated also helps preserve their shape while the car is parked.
If the car will sit for months, move it periodically or place it on stands to reduce constant load on one section of the casing. That is especially worthwhile on collector cars that only come out for shows or seasonal drives. Good storage habits protect appearance as much as function, which matters on a 1966 Dodge with visible whitewall or redline sidewalls.
How long do tires on a 1966 Dodge typically last?
Tires on a 1966 Dodge are usually judged more by age than by miles, because collector cars often see limited use. A good rule is to begin closer inspection once tires reach about five to seven years old and to consider replacement around ten years regardless of remaining tread, with the DOT date code used to confirm age. Bias-ply tires can still look serviceable while the rubber and casing have aged beyond ideal road use.
That matters on vintage Dodge cars because occasional weekend mileage can hide the effects of time. A tire with deep tread but advanced age may not be the tire you want for a long trip or fast highway run. Keeping a simple age record for each tire helps separate appearance from actual service life.
How often should tires on a 1966 Dodge be inspected?
Tires on a 1966 Dodge should be inspected before every drive and again before any longer outing or event. Check for sidewall cracking, weathering, cuts, bulges, uneven wear, and pressure loss, and take extra time to inspect visible whitewall or redline surfaces for age-related deterioration. Any collector car that sits for extended periods deserves more frequent visual checks than a regularly driven modern vehicle.
Routine inspection is one of the easiest ways to catch problems before they become an on-road issue. On a vintage Dodge, that quick walkaround should also include the spare and valve stems, since a car that appears ready for a drive may still be carrying an old spare or aged rubber components that were forgotten during storage.
Restoration & Authenticity
What tires were originally fitted to the 1966 Dodge Coronet?
A 1966 Dodge Coronet originally used bias-ply tires, which was standard practice for American passenger cars in this period. Coronet applications here include 775-14, 825-14, 695-14, and 735-14, all in numeric bias-ply sizing on 14-inch wheels. The exact original size depended on the specific Coronet model and equipment, not just the Coronet name alone.
That means a restoration-minded owner should verify the car's original application before choosing among the four Coronet sizes. Sidewall treatment matters too, since whitewall, blackwall, and redline choices can all change how authentic the finished car looks. For trim-specific or market-specific confirmation, a Dodge marque club or factory literature remains the best final check.
Does correct tire fitment matter for showing a 1966 Dodge?
Correct tire fitment matters on a 1966 Dodge because judges and knowledgeable enthusiasts often notice size, construction type, and sidewall style very quickly. A car from this era would normally be expected to wear a bias-ply tire in an appropriate numeric size, and an obviously mismatched sidewall treatment can look out of place even if the tire physically fits the wheel.
For a higher-level restoration, the tire should support the story the car is telling. A compact Dart with a broad whitewall and a performance-flavored Coronet with a redline can project very different period impressions. If the car is intended for formal judging, confirm the event's standards with a Mopar club or rulebook before making the final tire choice.
What is the difference between BFGoodrich and Firestone 775-14 tires for the 1966 Dodge Coronet?
For a 1966 Dodge Coronet using 775-14, BFGoodrich and Firestone both offer bias-ply tires with a 1580-pound load capacity at 32 psi and a 14-inch rim diameter. BFGoodrich appears in narrow whitewall and redline versions with a 5.50-6.00-inch rim-width range on some products, while Firestone appears in narrow whitewall with a 5.00-6.00-inch rim-width range. Weight runs about 22 to 23 pounds across these offerings.
That comparison makes the choice largely about appearance and wheel compatibility rather than a dramatic difference in rated load. If your Coronet restoration calls for a redline look, BFGoodrich covers that direction. If the car uses a narrower wheel within the approved range, the rim-width guidance becomes an equally important part of the decision.
Safety & Road Use
Are 1966 Dodge tires safe for highway driving?
Bias-ply tires for a 1966 Dodge can be used for highway driving when they are in good condition, correctly sized, and properly inflated, but they will behave like bias-ply tires rather than like modern radials. No speed ratings appear in these size offerings, so the more important practical limits usually come from tire age, condition, and the vehicle's own mid-1960s steering, braking, and suspension character rather than from a high modern speed category.
A well-sorted 1966 Dodge can cruise comfortably, but the driver should expect period road feel and should leave a wider margin for heat, stopping distance, and lane changes than in a newer car. The safest approach is to treat the tire, wheel, alignment, and overall chassis as one system and make sure each part is ready before extended highway use.
What inflation pressure should I use for 1966 Dodge tires?
Maximum load figures for 1966 Dodge tires are paired with 32 psi across every size here: 1150 pounds for 650-13, 1270 for 700-13, 1230 for 695-14, 1360 for 735-14, 1580 for 775-14, 1620 for 825-14, and 1740 for 855-14. Those figures describe the tire's rated load at that pressure, not necessarily the factory operating pressure Dodge originally recommended for every model.
Use the original owner's manual or factory service information as the first reference for the car's intended running pressure, then confirm that choice against the tire manufacturer's guidance for the exact reproduction tire. Pressure should never be copied from one size to another just because the cars share a model name, since the load and casing dimensions differ.
What should I check before taking a 1966 Dodge on a longer drive?
Before a longer drive in a 1966 Dodge, inspect each tire for cracking, cuts, bulges, irregular wear, and stable air pressure, and verify that the spare is usable and inflated. Whitewall and redline surfaces deserve a close look because cosmetic aging can sometimes reveal deeper sidewall issues. A longer trip also calls for checking wheel fasteners, steering play, brake condition, fluid levels, and the general mechanical readiness expected of a car from this era.
That pre-drive routine matters because a vintage Dodge often spends more time parked than driven, and storage can hide problems until the car is finally asked to cover real distance. Give yourself enough time for a short local shakedown before any highway run, so tire feel, vibration, and straight-line tracking can be evaluated before the trip truly begins.
