1974 Dodge Tire Fitment Guide

1974 Dodge vehicles use a broad mix of sizes depending on model. Challenger uses 735-14, F70-14, and F78-14; Charger and Coronet share E78-14, F78-14, H78-14, HR78-14, G78-14, G70-14, and GR70-14; Colt uses 600-13, A78-13, and BR70-13; Dart uses D78-14, DR78-14, 695-14, and E70-14. Monaco uses J78-15, JR78-15, L78-15, LR78-15, G78-15, and HR78-15, while Pickup and Ramcharger branch into several 15-, 16-, and 16.5-inch truck sizes.

That spread means year and make alone are not enough for a confident tire choice on a 1974 Dodge. Charger and Coronet overlap heavily, but Colt, Dart, Monaco, Pickup, and Ramcharger all have their own fitment paths, and Dodge Pickup alone spans three different wheel diameters. Match the exact model first, then confirm the size code on the car's current tires or wheels before narrowing to a particular product line.

On a 1974 Dodge, an alphanumeric size such as F78-14 or G78-15 uses a period-correct U.S. sizing system. The first letter identifies the tire's general size class, the number group reflects its profile family, and the final number is the wheel diameter in inches. When an R appears in the code, as in HR78-14, GR70-14, or LR78-15, it indicates radial construction; when there is no R, the tire is bias-ply.

That distinction matters because two similar-looking codes can point to very different driving character and restoration goals. A buyer comparing G70-14 and GR70-14 for a 1974 Dodge Charger or Coronet is not just choosing a sidewall style, but also choosing between bias-ply and radial construction. Once the code is decoded correctly, it becomes much easier to compare period appearance, available sidewalls, and the type of use the car will see.

No, 1974 Dodge models do not use the same tire size. Charger and Coronet share the same group of seven 14-inch sizes, but Challenger has its own three-size set, Colt uses 13-inch sizes, Dart uses a different four-size 14-inch group, Monaco moves to 15-inch sizes, and Pickup and Ramcharger use truck-oriented 15-, 16-, and 16.5-inch applications. Some sizes overlap across models, but many are model-specific.

In practical terms, a 1974 Dodge buyer should identify the exact model before focusing on brand or sidewall style. That is especially important if the vehicle is a Pickup, since the difference between 700-15, 750-16, and 800-16.5 is more than cosmetic and points to different wheel diameters altogether. Shared Dodge styling themes do not translate into one universal tire fitment across the entire lineup.

The right choice depends on which radial and bias-ply sizes apply to your exact 1974 Dodge model. Charger and Coronet can move between bias-ply sizes such as G70-14 or G78-14 and radial codes such as GR70-14 or HR78-14, while Dart, Colt, Monaco, and some Pickup applications also have both construction paths in parts of their ranges. Bias-ply keeps the car closer to original 1970s road feel and appearance, while radial-format options reflect the era's transition toward more modern construction.

A restoration-minded owner usually starts with the bias-ply code that matches the car's original style, especially for show use or a period-correct stance. A driver who plans to use a 1974 Dodge more regularly may prefer a radial-format size when one belongs to that model's fitment group. The key is to stay within the sizes appropriate to your model rather than treating radial and bias-ply choices as interchangeable across the whole Dodge range.

1974 Dodge tires are available in a wide range of sidewall styles depending on size. Across the range you can find blackwalls, narrow whitewalls, wide whitewalls, dual white stripes, dual redlines, redlines, pin white stripes, and raised white letters. Passenger-car sizes such as G70-14, F70-14, 695-14, and several 15-inch Monaco sizes offer the broadest visual choices, while truck-oriented 16- and 16.5-inch Pickup sizes stay mostly with blackwall utility styling.

Matching the sidewall to the vehicle's role matters almost as much as matching the size code. A 1974 Dodge Monaco or Coronet often looks right with whitewalls or stripe treatments, while a Pickup or Ramcharger can lean more naturally toward blackwall truck tires unless you are building a more styled restoration. If show authenticity matters, compare your intended sidewall look against period photos, brochures, and marque-club guidance for your model.

1974 Dodge tires are available from several brands, including BFGoodrich, Firestone, Goodyear, Coker Classic, STA, US Royal, and Lester. The exact brand mix depends on size: F70-14 and G70-14 center on Firestone and Goodyear; 735-14 and many whitewall-oriented sizes lean toward BFGoodrich or Coker Classic; truck sizes such as 800-16.5, 875-16.5, and 950-16.5 are strongly associated with STA. Some sizes are represented by only one brand family, while others have broader overlap.

That means brand choice usually comes after fitment choice, not before it. A buyer with a 1974 Dodge Dart on 695-14 can compare BFGoodrich and US Royal options, while a Pickup owner on 16.5-inch truck rubber may be choosing among different STA series in the same brand. Pick the correct size and construction first, then compare the brand's sidewall treatment, load figures, and visual character for the final decision.

Rim width depends on the exact tire size used on the 1974 Dodge. Examples include 5.00 to 5.50 inches for 735-14 and 700-15, 6.00 to 7.00 inches for F70-14 and E70-14, 5.00 to 7.00 inches for F78-14 and G78-14, 5.50 to 8.00 inches for H78-14, L78-15, and LR78-15, 6.00 to 6.50 inches for 800-16.5, and 6.50 to 6.75 inches for 950-16.5. Compact 600-13 uses a notably narrow 4.00 to 4.50 inch rim range.

Those ranges are a reminder that sharing the same wheel diameter does not automatically mean every tire is right for every wheel. A 14-inch Dodge wheel may still differ in width requirements depending on whether the tire is 695-14, F70-14, or H78-14. Before final selection, verify the actual wheel width on your 1974 Dodge so the tire's approved rim-width range matches the wheel already on the car or truck.

Most 1974 Dodge products in these size groups do not carry a tube-type marking in the size description, and at least some applications are explicitly tubeless, such as the STA Traxion 8 Ply Rated Tubeless in E78-14. At the same time, tube status is not stated uniformly across every size and product family. That means inner-tube use can vary by the exact tire you choose rather than by model alone.

The safest approach is to confirm the sidewall marking and the wheel type together before installation. Older original wheels on a 1974 Dodge may have condition issues or design details that affect whether tubeless service is appropriate even when a tire itself can run that way. Handle tube choice as a product-by-product and wheel-by-wheel decision instead of assuming one answer covers every Charger, Dart, Pickup, or Ramcharger fitment.

A stored 1974 Dodge should be kept in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that can age rubber. Keep the tires properly inflated, avoid letting the vehicle sit in standing moisture, and move it periodically so one section of tread is not carrying the load for months at a time. Bias-ply tires, which make up much of the 1974 Dodge range, are especially prone to flat-spotting during long static storage.

If the car or truck will sit for an extended season, many owners either roll it occasionally or place it on stands to reduce stress on the carcass. That practice is especially helpful for heavier applications such as Monaco, Pickup, and Ramcharger. Tire covers and a clean floor also help, but the biggest gains come from controlling light, ozone, moisture, and long periods of unmoving weight on one part of the tire.

On a collector vehicle such as a 1974 Dodge, tire life is usually judged more by age and condition than by mileage alone. A useful rule is to evaluate tires closely once they are around five to seven years old and to consider replacement as they approach the ten-year mark, even if tread depth still looks healthy. The DOT date code on the tire helps establish age, and sidewall cracking, hardening, or persistent pressure loss can matter more than odometer use.

That age-based approach is especially important on cars and trucks that are driven only occasionally, because low mileage can hide rubber aging. A 1974 Dodge stored indoors may age more gracefully than one parked in heat and sun, but time still works against the casing. For a driver-quality or show vehicle alike, replace based on condition and age rather than waiting for the tread to wear out.

Tires on a 1974 Dodge should be inspected before every drive, and more carefully before any longer outing. Look for sidewall cracking, cuts, bulges, uneven tread wear, weathering around the bead area, and any sign that the tire is not holding pressure consistently. On heavier Dodge Pickup and Ramcharger applications, also pay close attention to aging valve stems and any irregular wear that suggests alignment or suspension issues.

A more detailed inspection every few months is smart even if the vehicle is rarely used. That check should include the spare, because an old spare on a classic Dodge often gets overlooked until it is suddenly needed. Catching small issues early is one of the best ways to avoid roadside trouble and to protect suspension, steering, and braking systems that may already be carrying the normal compromises of a 1970s vehicle.

A 1974 Dodge Charger originally belonged to an era when bias-ply tires were still common, even as radial construction was becoming more visible in the market. Within the Charger fitment range, sizes such as E78-14, F78-14, H78-14, G78-14, and G70-14 represent the traditional bias-ply side of the period, while HR78-14 and GR70-14 reflect radial-era alternatives that also fit the model family. Original-equipment branding could vary by market and trim, so size and construction are usually the first authenticity checkpoints.

For an accurate restoration, treat the period-correct size code, sidewall style, and construction type as the core of the decision. A redline or raised white letter tire may be right for one 1974 Dodge Charger presentation, while a whitewall or blackwall could suit another. Factory literature, surviving original cars, and marque-club resources are the best way to confirm exactly what belongs on your Charger before choosing among reproduction options.

Yes, correct tire fitment matters on a 1974 Dodge that will be judged for originality. Size code, construction type, sidewall treatment, and overall visual stance all contribute to whether the car or truck looks right for its era and model. A radial-format code on a restoration aimed at factory bias-ply authenticity, or a bright performance sidewall on a formal Monaco-style presentation, can stand out immediately to knowledgeable judges and enthusiasts.

That does not mean every show car needs the exact same visual treatment, because period dealer practices, replacement history, and trim level can influence what looks appropriate. It does mean the tire should support the story the vehicle is telling. If your 1974 Dodge is headed for marque judging, compare your planned size and sidewall against event standards and club guidance rather than assuming any tire that physically fits will satisfy authenticity expectations.

For a 1974 Dodge in sizes such as F70-14, G70-14, and E70-14, Firestone Wide Oval and Goodyear Custom Wide Tread occupy similar period territory but differ in sidewall offerings and some wheel-width ranges. Firestone Wide Oval appears in redline, pin white stripe, and raised white letter versions, while Goodyear Custom Wide Tread appears in raised white letter or redline forms depending on size. On G70-14, Firestone uses a 6.50 to 7.00 inch rim range, while Goodyear extends from 6.0 to 8.0 inches.

That makes the choice partly visual and partly practical. If your 1974 Dodge has a wheel at the wider end of the acceptable range, the Goodyear specification may open more room, while Firestone may better match a particular sidewall style you want. Compare the exact rim width on the car, then choose the product whose sidewall treatment and sizing character best align with your restoration goal.

A properly matched, properly maintained tire can be suitable for normal highway use on a 1974 Dodge, but the answer depends on the exact size, construction, and condition. Most of the available fitments here are bias-ply or period-style radial applications, and no explicit speed-letter ratings appear in these size descriptions. That means the overall safety picture is shaped as much by age, inflation, wheel condition, and the vehicle's 1970s brakes, steering, and suspension as by the tire itself.

For real-world use, focus on fresh rubber, correct size selection, stable inflation, and a complete mechanical inspection before long trips. A 1974 Dodge Pickup or Ramcharger with truck tires has a different road feel from a Charger or Dart on passenger-car rubber, even if both are technically highway-capable. The safest approach is to treat highway readiness as a system question that includes the tire, the wheel, and the vehicle around it.

Inflation pressure on a 1974 Dodge should start with the vehicle's factory recommendation, then be checked against the tire's own rated load-and-pressure relationship for the exact size you choose. Examples include 1360 pounds at 32 psi for 735-14, 1620 pounds at 32 psi for G70-14 and G78-15, 1770 pounds at 32 psi for H78-14 and some H78-15 products, 2045 pounds at 60 psi for 800-16.5, and 2780 pounds at 60 psi for 950-16.5. Those figures are not interchangeable from one size to another.

Passenger-car and truck applications within the 1974 Dodge range are too different to use one blanket pressure rule. A Monaco on J78-15, a Dart on 695-14, and a Pickup on 950-16.5 each operate in different load and pressure territory. Use the tire maker's rated pressure as a limit tied to load capacity, then fine-tune within the vehicle manufacturer's guidance for your exact model and intended use.

Before a longer drive in a 1974 Dodge, inspect every tire for cracking, cuts, bulges, uneven wear, and proper cold inflation. Check the spare as carefully as the four tires on the ground, because classic-car spares are often much older than the main set. On heavier Dodge Pickup and Ramcharger applications, verify that the load range and wheel condition match the intended trip, and look over the valve stems and beads for signs of age or leakage.

Tire checks should be part of a broader pre-trip routine on a vehicle of this age. Brakes, belts, hoses, steering play, wheel bearings, and fluid levels deserve attention before the first highway mile. A long drive in a 1974 Dodge is far more enjoyable when the tire inspection is handled early, because it reduces the chance of chasing vibration, heat buildup, or pressure problems after the trip is already underway.
