The 1970 Dodge Challenger arrived at the height of Detroit’s muscle car era, with a long hood, aggressive stance, and a broad range of engine combinations that gave the E-body platform very different personalities from one version to the next. That matters at tire level, because this Challenger uses several bias-ply fitments across both 14-inch and 15-inch wheel diameters, including staggered T/A sizes. Buyers can sort through Polyglas GT, Wide Oval, Custom Wide Tread, Speedway Wide Tread, Coker Classic, STA, and M&H options, with sidewall treatments ranging from blackwall and wide whitewall to redline, pin white stripe, and raised white letter. The right choice depends on the exact sub-model, wheel setup, and whether the goal is muscle-era appearance, restoration character, or road-use practicality.
Which Tire Size Is Right for The 1970 Dodge Challenger
The 1970 Dodge Challenger uses seven primary tire sizes, and the correct one depends first on the exact sub-model and wheel diameter. Some versions use 14-inch bias-ply tires, others use 15-inch bias-ply tires, and the T/A uses different front and rear sizes. Before choosing a tire, confirm whether the car is a T/A, identify the engine-based configuration, and verify the actual wheel diameter on the car today.
E60-15 is an alphanumeric bias-ply size in which the letter and number identify a vintage width and profile family, while the final 15 indicates a 15-inch rim. On the 1970 Dodge Challenger, this size appears on certain 15-inch applications including T/A front fitment and some 340-equipped versions. Available choices center on Goodyear Polyglas GT with raised white letter styling. This size is worth close attention when preserving a muscle-era 15-inch look, but the exact sub-model and wheel setup still need to match before selection.
G60-15 is a vintage alphanumeric bias-ply tire size, with the final 15 designating a 15-inch rim and the letter-series code indicating a broader, lower-profile muscle car format than many 14-inch fitments. On the 1970 Dodge Challenger, it serves as the rear size on T/A applications. Product choices include Goodyear Polyglas GT in raised white letter form and an M&H Racemaster Muscle Car Drag Tire in blackwall trim. It is the right place to focus when a staggered rear muscle car presentation is part of the car’s intended setup.
E70-14 uses the vintage alphanumeric bias-ply system, where the letter and series number describe the tire family and the final 14 identifies a 14-inch rim. On the 1970 Dodge Challenger, this size appears on certain 225 and 318 engine configurations. It has one of the broadest assortments, including Firestone Wide Oval and Goodyear Custom Wide Tread choices with redline, pin white stripe, and raised white letter sidewalls. This size gives a buyer room to balance traditional fitment with a specific period-style appearance on a small-block 14-inch setup.
E78-14 is another vintage alphanumeric bias-ply size, with the 14 indicating rim diameter and the E78 designation reflecting an older width-and-profile convention. On the 1970 Dodge Challenger, it appears alongside E70-14 on certain 225 and 318 engine applications rather than across the full model range. Available products include a Coker Classic wide whitewall and STA blackwall tires in Traxion and Transport Highway series. This size deserves careful comparison when the goal is a more traditional 14-inch presentation and the car’s exact wheel and use pattern differ from muscle-focused styling choices.
F70-14 is a vintage alphanumeric bias-ply size in which the F70 designation marks the tire family and the final 14 confirms a 14-inch rim. On the 1970 Dodge Challenger, it fits certain 383 and 440 engine combinations. This size offers extensive choice across Firestone Wide Oval and Goodyear Custom Wide Tread and Speedway Wide Tread lines, with redline, pin white stripe, and raised white letter sidewall treatments. It is a key size for buyers trying to match a big-block Challenger’s 14-inch stance with a specific muscle-era visual character.
F78-14 follows the same vintage alphanumeric bias-ply format, with the final 14 indicating a 14-inch wheel and the F78 code representing a different profile family than F70-14. On the 1970 Dodge Challenger, it also appears on certain 383 and 440 engine applications, so the exact setup matters before choosing between the two. The available offering centers on a Coker Classic 2.375-inch wide whitewall. This size makes the most sense when the car calls for a 14-inch bias-ply tire with a more traditional sidewall presentation rather than a muscle-style stripe or letter treatment.
Fit(s): w/426 Eng. and w/426 Eng. w/aluminum wheels
Construction: Bias Ply|Rim: 15 in
F60-15 is a vintage alphanumeric bias-ply size with a 15-inch rim diameter and a low-profile muscle car character consistent with period high-performance fitments. On the 1970 Dodge Challenger, this size appears on 426 engine applications. The available choices are Goodyear Polyglas GT raised white letter tires, offered in the same size with matching bias-ply construction and 15-inch fitment. This size is the one to evaluate when the Challenger carries the 426-based configuration and the owner wants to stay with the bold 15-inch muscle-era tire presentation associated with that setup.
Sub-model fitment on the 1970 Dodge Challenger is not one-size-fits-all, because tire selection changes by engine-based configuration and by T/A front-versus-rear placement. Checking the exact sub-model matters just as much as checking wheel diameter, especially on cars that may no longer have their original wheels.

1970 Dodge Challenger T/A Front
The 1970 Dodge Challenger T/A Front uses a dedicated 15-inch bias-ply front fitment rather than the same size carried at the rear. Tire selection here should preserve the T/A’s staggered setup and match the front wheel configuration before choosing among available muscle-era style options.
The 1970 Dodge Challenger T/A Rear uses a different 15-inch bias-ply tire size than the front, making rear fitment a separate decision. That means the buyer should evaluate rear tire options with the staggered arrangement in mind instead of assuming the front and rear sizes are interchangeable.
The 1970 Dodge Challenger T/A w/aluminum wheels Front keeps the same basic front tire-fitment pattern as the standard T/A front setup. Tire choice still depends on maintaining the proper 15-inch front application and confirming the wheel dimensions of the aluminum-wheel car before moving ahead.
The 1970 Dodge Challenger T/A w/aluminum wheels Rear follows the dedicated rear 15-inch bias-ply arrangement used on T/A applications. Rear tire selection should focus on keeping the correct staggered relationship and verifying the actual aluminum wheel setup on the car, especially if it has been restored or modified.
The 1970 Dodge Challenger w/225 & 318 Eng. uses 14-inch bias-ply fitment, with two applicable primary sizes in this configuration. Choosing between them starts with confirming which wheel and tire setup the car actually carries, then deciding whether the goal is a traditional whitewall look or a more muscle-oriented sidewall treatment.
The 1970 Dodge Challenger w/225 & 318 Eng. w/aluminum wheels also uses 14-inch bias-ply tire fitments rather than moving to the larger 15-inch T/A-style arrangement. Tire selection should begin with wheel confirmation, since aluminum-wheel cars may have changed over time even when the covered fitment pattern remains in the same size family.
The 1970 Dodge Challenger w/340 Eng. uses a 15-inch bias-ply tire fitment that differs from the 14-inch setups found on other versions. That makes the key decision less about multiple primary sizes and more about choosing the right 15-inch muscle-era tire style for the car’s current wheels and intended presentation.
The 1970 Dodge Challenger w/340 Eng. w/aluminum wheels stays with the same 15-inch bias-ply fitment pattern as the corresponding non-aluminum-wheel version. Tire selection should still include a wheel check, since restored or updated aluminum-wheel cars sometimes differ from their original dimensions even when the nominal tire size remains the same.
The 1970 Dodge Challenger w/383 & 440 Eng. uses 14-inch bias-ply tire fitments, with more than one primary size associated with this big-block configuration. The buyer should first identify which 14-inch setup is on the car, then sort through stripe, letter, or more traditional sidewall choices that suit the intended look.
The 1970 Dodge Challenger w/383 & 440 Eng. w/aluminum wheels follows the same 14-inch fitment pattern as the comparable steel-wheel-based configuration. Choosing tires here still starts with confirming which 14-inch size the car is using, then comparing appearance-oriented options within that size rather than assuming every big-block Challenger used the same tire.
The 1970 Dodge Challenger w/426 Eng. uses a dedicated 15-inch bias-ply tire size rather than the 14-inch big-block alternatives. That simplifies the size decision, but buyers still need to confirm the car’s present wheel setup and choose the tire presentation that best matches the restoration or road-use plan.
The 1970 Dodge Challenger w/426 Eng. w/aluminum wheels uses the same 15-inch bias-ply fitment pattern as the corresponding 426 application without the aluminum-wheel note. Tire choice therefore centers on correct 15-inch fitment and visual character, with a careful wheel check still worthwhile on any car that has changed hands or been restored.
Bias-Ply to Radial Tire Conversion for the 1970 Dodge Challenger
Four of the 1970 Dodge Challenger’s 14-inch bias-ply sizes have radial-equivalent options. E70-14 and E78-14 can be compared to 185R14 as an 80-series metric radial, P195/75R14 as a 75-series P-metric radial, and P205/70R14 as a 70-series P-metric radial. F70-14 and F78-14 can be compared to 195R14, P205/75R14, P215/70R14, and 750R14 as a bias-look radial. These alternatives use different sizing conventions, and the stated 4-6 inch recommended rim-width range should be checked along with wheel diameter and vehicle clearance.

These 1970 Dodge Challenger tire FAQs focus on the real decisions owners face: identifying the correct size by sub-model, understanding 14-inch versus 15-inch fitment, comparing bias-ply and radial-equivalent choices, and checking the car carefully before road use.
Tire Size & Fitment
What tire size fits a 1970 Dodge Challenger?
A 1970 Dodge Challenger can use E60-15, G60-15, E70-14, E78-14, F70-14, F78-14, or F60-15, depending on the exact sub-model. All of these are bias-ply primary fitments, and the model range includes both 14-inch and 15-inch wheel diameters.
The first step is identifying the exact configuration, because a T/A uses different front and rear sizes while engine-based versions can use different 14-inch or 15-inch tires. It is also smart to confirm the wheels currently on the car, since restorations and older modifications can change what size is actually appropriate.
What size rim does a 1970 Dodge Challenger use?
The 1970 Dodge Challenger uses both 14-inch and 15-inch rim diameters, depending on the version of the car. E70-14, E78-14, F70-14, and F78-14 are 14-inch fitments, while E60-15, G60-15, and F60-15 are 15-inch fitments.
That means rim diameter has to be confirmed before ordering any tire, especially on a car that may have had wheel swaps over the years. Looking at the current wheel and matching it to the correct sub-model fitment helps avoid choosing a tire that is right in appearance but wrong for the wheel actually on the Challenger.
Why does the 1970 Dodge Challenger have more than one tire size?
The 1970 Dodge Challenger was offered in multiple engine-based configurations, and tire fitment changes across those versions. The T/A also uses a staggered setup with one size at the front and a different size at the rear, which adds another layer to fitment selection.
That variety means the correct tire is tied to the car’s exact sub-model rather than the Challenger name alone. Owners should confirm whether the car is a T/A, a 225 or 318 version, a 340 car, a 383 or 440 car, or a 426 car, then verify the wheel diameter before narrowing down brand and sidewall style.
Bias-Ply & Radial Options
Is F70-14 a bias-ply or radial tire for the 1970 Dodge Challenger?
F70-14 is a primary bias-ply tire size for the 1970 Dodge Challenger. It appears on certain 383 and 440 engine applications and uses the vintage alphanumeric sizing system associated with period muscle car fitment.
Radial alternatives do exist for F70-14, but they should be treated as equivalents rather than as the same thing as the original bias-ply construction. Buyers comparing options should keep the 14-inch wheel requirement in mind and also check rim-width suitability, overall vehicle setup, and clearance before moving away from the bias-ply format.
What radial tire sizes are equivalent to F70-14 on a 1970 Dodge Challenger?
Radial equivalents for F70-14 include 195R14 as an 80-series metric radial, P205/75R14 as a 75-series P-metric radial, P215/70R14 as a 70-series P-metric radial, and 750R14 as a bias-look radial. These are comparison sizes for the original 14-inch bias-ply fitment.
Each option uses a different sizing convention, so the decision is not just radial versus bias-ply. The 4-6 inch recommended rim-width range attached to the equivalent setup is an important checkpoint, and wheel diameter, suspension clearance, and the car’s intended appearance should all be reviewed before making the change.
What should I check before converting my 1970 Dodge Challenger from bias-ply to radial tires?
Start by matching the radial equivalent to the Challenger’s original primary size and confirming that the car still has the correct wheel diameter. On 14-inch applications with equivalents, the available radial comparisons vary by size family, and F70-14 or F78-14 can also be considered with a 750R14 bias-look radial.
Wheel width should be reviewed along with steering and fender clearance, especially if the car has aftermarket wheels or altered ride height. It also helps to think about the result you want, because a standard metric radial, a P-metric radial, and a bias-look radial can lead to different visual character even when they are all valid equivalent paths.
Choosing the Right Tire
What should I consider when choosing a 1970 Dodge Challenger tire?
Begin with the exact sub-model and correct primary size, because the 1970 Dodge Challenger spans several 14-inch and 15-inch bias-ply fitments. After size is settled, the next factors are construction retention, sidewall appearance, brand, tire series, and how closely the tire matches the character you want for the car.
A T/A owner may be focused on preserving a staggered muscle-car look, while a 225 or 318 car may lean toward a more traditional 14-inch presentation. Rim compatibility matters as well, since some products are built around specific wheel-width ranges and the Challenger may no longer be wearing its original wheels.
What sidewall styles are available for 1970 Dodge Challenger tires?
Sidewall choices for 1970 Dodge Challenger tires include blackwall, wide whitewall, redline, pin white stripe, and RWL raised white letter styles. The exact sidewall treatment depends on the tire size and series, so every appearance option is not available in every Challenger fitment.
That makes sidewall style a second-step decision after confirming the proper size. Muscle-oriented 14-inch and 15-inch sizes often have stripe or lettered options, while some other fitments lean more traditional with whitewall or blackwall choices, so appearance goals should be matched to the correct tire family rather than selected in isolation.
What brands offer tires for the 1970 Dodge Challenger?
1970 Dodge Challenger tires are available from Goodyear, Firestone, Coker Classic, STA, and M&H Racemaster. Brand availability changes by size, with some fitments offering several choices and others being limited to one brand or one style of bias-ply tire.
The useful comparison is not brand name alone but the combination of size, tire series, sidewall presentation, and wheel compatibility. A buyer should first narrow the search to the correct Challenger fitment, then compare whether a Polyglas GT, Wide Oval, Custom Wide Tread, Coker Classic, STA, or drag-oriented option best suits the car’s purpose.
Restoration & Appearance
Which tire should I choose for a period-style 1970 Dodge Challenger?
A period-style 1970 Dodge Challenger tire starts with the correct primary bias-ply size for the exact sub-model. From there, choices such as Goodyear Polyglas GT, Firestone Wide Oval, Goodyear Custom Wide Tread, Goodyear Speedway Wide Tread, or Coker Classic Bias Ply can shape the final look in different ways.
The best direction depends on whether the car is being presented as a muscle-era performance car or with a more traditional whitewall appearance. Exact originality claims should be checked against vehicle-specific historical references if that level of restoration matters, because the right size alone does not establish the right brand or sidewall treatment.
How does tire construction affect the appearance of a restored 1970 Dodge Challenger?
On a restored 1970 Dodge Challenger, staying with the original-style bias-ply construction preserves the vintage tire shape and overall presentation associated with the car’s period fitment. That is especially noticeable on muscle-era sizes such as E60-15, G60-15, F70-14, and F60-15.
A radial equivalent can change the visual impression even when it remains in the same general fitment family, because the sizing format and sidewall character may differ. Buyers who want a more traditional look but still want a radial option may find the bias-look radial route useful on certain 14-inch applications, provided the wheel and vehicle setup are checked first.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1970 Dodge Challenger?
Yes, modifications can affect tire fitment on a 1970 Dodge Challenger even when the tire size is correct for the original application. Wheel swaps, changes in wheel width, altered ride height, suspension work, and body modifications can all influence how a 14-inch or 15-inch tire sits and clears.
That matters even more on staggered T/A setups and on cars that have changed owners several times. A good practice is to verify current wheel diameter first, then check clearance at steering lock and through suspension travel so the selected tire suits the car as it exists today, not only as it may have left the factory era.
What should I inspect before driving a 1970 Dodge Challenger on new tires?
Before driving a 1970 Dodge Challenger on new tires, inspect the wheels for damage or distortion, confirm the wheel diameter and width match the tire, and make sure the tires are mounted and inflated properly. A quick visual check for even seating and adequate clearance is also important.
Collector cars benefit from a broader inspection before road use, including steering feel, suspension condition, brake performance, and whether any tire contacts the fender or chassis through turns or bumps. It also helps to recheck air pressure after initial use, since a fresh installation is the right time to catch setup issues early.
How should 1970 Dodge Challenger tires be maintained?
1970 Dodge Challenger tires should be maintained with regular pressure checks, visual inspections for cracking, cuts, bulges, uneven wear, and signs of air loss, especially if the car is driven infrequently. Bias-ply collector tires also benefit from periodic inspection even when tread wear is minimal.
Storage conditions matter just as much as mileage on an older vehicle. Keeping the Challenger away from prolonged heat, direct sunlight, moisture, and ozone sources helps protect sidewalls, and it is wise to inspect the tires before any longer drive because collector cars often age their tires out long before they wear them out.
