1971 Dodge Demon Tires

A 1971 Dodge Demon can use 6.45-14, 695-14, or E70-14 depending on the sub-model. The six-cylinder Demon uses 6.45-14 or 695-14 bias-ply tires, while the Demon w/340 Eng. uses E70-14 bias-ply tires. All of these are 14-inch fitments.

The key is matching the tire size to the exact version of the car rather than treating every 1971 Demon the same. It also helps to confirm that the car still has the correct 14-inch wheels, since wheel changes over the years can complicate selection even when the original tire size is known.

The primary tire fitments for the 1971 Dodge Demon all use a 14-inch rim diameter. That applies to the 6.45-14, 695-14, and E70-14 bias-ply sizes associated with this model year. Rim width varies by tire size and by specific tire product.

Confirming wheel diameter is the first step, but it should not be the only one. A 14-inch wheel still needs to be appropriate for the tire’s width and construction, especially if the car has replacement wheels or if a radial equivalent is being considered instead of the original bias-ply size.

The 1971 Dodge Demon has more than one tire size because fitment changes by sub-model. Six-cylinder cars use the smaller 6.45-14 or 695-14 bias-ply sizes, while the Demon w/340 Eng. uses the larger E70-14 bias-ply size. The difference reflects the fact that not every Demon configuration was equipped the same way.

That means the first decision is identifying the exact version of the car, not simply choosing a sidewall style or brand. Once the sub-model is confirmed, the remaining choice becomes more straightforward: stay with the period-style bias-ply size, or for 695-14 and E70-14, evaluate one of the available radial equivalents carefully.

For the 1971 Dodge Demon w/340 Eng., E70-14 is a vintage alphanumeric bias-ply tire size. In this format, the letter and series number identify the tire’s size family, while the 14 indicates the wheel diameter. It is part of the original-style bias-ply fitment for that sub-model.

That matters because an alphanumeric bias-ply size should not be treated the same as a modern metric radial even if both mount on 14-inch wheels. Buyers comparing tire types should keep the original appearance goal, wheel width, and vehicle clearance in mind before deciding whether to remain with E70-14 bias-ply construction or explore a radial equivalent.

Radial equivalents for 695-14 include 175R14 as an 80-series metric radial, P185/75R14 as a 75-series P-metric radial, and P195/70R14 as a 70-series P-metric radial. These sizes provide modern radial-format alternatives while staying in the same general fitment conversation as the original 695-14 bias-ply size.

The stated rim-width range for those equivalents is 4 to 6 inches, which makes wheel confirmation especially important before making a change. It is also wise to compare the actual wheel setup and available clearance on the car, because an equivalent size is a useful alternative, not an automatic one-size-fits-all substitution.

Start by confirming the Demon’s original tire size and sub-model, then match any radial equivalent to the correct 14-inch wheel and the appropriate wheel-width range. For 695-14 and E70-14, radial alternatives are available, but they follow metric or P-metric sizing formats rather than the original bias-ply code.

A conversion should also include a close look at wheel condition, tire-to-fender clearance, steering clearance, and the car’s current suspension setup. If the car has replacement wheels, altered ride height, or front-end wear, those factors can influence how a radial alternative behaves and whether the change is practical.

A 695-14 tire choice for a 1971 Dodge Demon starts with confirming that the car is one of the six-cylinder applications that uses this size. From there, the main variables are brand, tire series, sidewall style, and wheel-width compatibility. Available 695-14 choices include BFGoodrich, US Royal, and Goodyear in several classic bias-ply lines.

The visual presentation can change quite a bit within the same size, since 695-14 is offered in blackwall, narrow whitewall, dual redline, raised white letter, and Blue Streak-style sidewalls. Matching the tire to the car’s intended appearance and road use usually matters more here than finding a different size, since 695-14 already opens a broad period-style selection.

Sidewall choices for 1971 Dodge Demon tires vary by size. In 695-14, available styles include blackwall, narrow whitewall, dual redline, raised white letter, and a raised white letter Blue Streak presentation. In E70-14, the options include pin white stripe, redline, and raised white letter.

That makes sidewall styling one of the biggest appearance decisions on this page, especially for buyers trying to match a certain early-1970s street look. The best approach is to choose the correct tire size first, then select the sidewall treatment that fits the car’s personality and the level of restoration-oriented detail you want.

Tire options for the 1971 Dodge Demon include BFGoodrich, US Royal, Goodyear, and Firestone, depending on the size. BFGoodrich, US Royal, and Goodyear appear in 695-14 offerings, while Firestone and Goodyear are available in E70-14. Brand availability follows the tire size rather than applying evenly across every Demon configuration.

Because the size determines the product pool, it helps to settle the fitment question before comparing brands. Once that is done, the more useful comparisons usually involve tire series, sidewall treatment, load specification at the stated pressure, and rim-width suitability instead of assuming that every brand offers the same style in every size.

For a period-style 1971 Dodge Demon, the starting point is the correct original-format bias-ply size for the car’s sub-model: 6.45-14 or 695-14 for six-cylinder cars, and E70-14 for the Demon w/340 Eng. Staying in the proper bias-ply size keeps the tire’s visual language closer to what belongs on an early-1970s compact Mopar.

After size is settled, the appearance choice becomes more specific. A six-cylinder car might lean toward blackwall, whitewall, or dual redline in 695-14, while an E70-14 setup offers redline, pin white stripe, or raised white letter styles. If exact originality matters, marque-specific references should guide the final sidewall and brand decision.

Tire construction affects both stance and visual character on a restored 1971 Dodge Demon. The original primary fitments are bias-ply sizes, so retaining bias-ply construction preserves the traditional profile and sidewall presentation associated with the car’s era. That is especially important when the goal is a restoration-oriented or period-style look.

A radial equivalent can still be worth considering for road use, but it changes the conversation from preservation of original-style construction to a modern alternative in a comparable size range. Buyers who care most about appearance usually choose the correct bias-ply size first, then narrow the look through sidewall style and tire series.

Yes, modifications can affect tire fitment on a 1971 Dodge Demon even when the original tire size is known. Aftermarket wheels, changes in wheel width, altered offset, lowered suspension, replacement springs, or bodywork changes can all influence whether a given bias-ply or radial-equivalent tire works comfortably on the car.

A Demon that no longer has its original wheel and suspension relationship should be checked more carefully than a stock car. Measure the actual wheel diameter and width, then inspect clearance at the fender, steering components, and suspension travel points before mounting new tires, especially when moving away from the original bias-ply construction.

Before driving a 1971 Dodge Demon on new tires, inspect the wheels for damage or corrosion, confirm the wheel diameter matches the intended tire, and make sure the valve stems and mounting surfaces are in good condition. It is also smart to check the car’s steering, alignment, and suspension condition before putting fresh tires into service.

Once the tires are mounted, verify inflation, watch for any unusual rubbing, and recheck clearance at full steering lock if the car uses the front fitments. A short initial drive followed by another visual inspection can catch issues early, particularly on a collector car that may have spent long periods parked.

Collector-car tire care for a 1971 Dodge Demon begins with regular pressure checks, visual inspection, and attention to age-related deterioration. Even if tread still looks good, a low-use car can develop sidewall cracking, flat spotting, air loss, or weathering simply from time, storage conditions, and infrequent driving.

The car should be stored away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment when possible. It also helps to inspect tires before every meaningful drive rather than assuming they are ready because the car has not been used much. That routine is especially important on older bias-ply fitments and weekend-driven vehicles.
