1968 Plymouth Belvedere & Satellite Tires

A 1968 Plymouth Belvedere & Satellite can use 735-14, 775-14, 825-14, 855-14, or F70-15, depending on the exact sub-model. The Base uses 735-14 or 775-14, the Conv. & Air uses 775-14 or 825-14, the Wagon uses 825-14 or 855-14, and the 426 Hemi V8 application uses F70-15.

That means the correct first step is identifying the exact version of the car rather than choosing by appearance alone. The Hemi application also changes to a 15-inch wheel, so wheel diameter should be confirmed before ordering. If the car has been modified over the years, checking the actual wheels on the vehicle is just as important as knowing the original size range.

The 1968 Plymouth Belvedere & Satellite uses either a 14-inch or 15-inch rim, depending on the tire size and sub-model. Sizes 735-14, 775-14, 825-14, and 855-14 are 14-inch fitments, while F70-15 is a 15-inch fitment used on the 426 Hemi V8 application.

Rim diameter is the most important wheel measurement to confirm because a 14-inch tire cannot be mounted on a 15-inch wheel, and the reverse is also true. Wheel width matters as well, especially when comparing different product options or considering a radial equivalent. A quick check of the wheel stamping or the mounted wheel itself helps avoid ordering the right tire in the wrong diameter.

No. Tire size varies across the 1968 Plymouth Belvedere & Satellite range. Base, Conv. & Air, and Wagon versions all use different combinations within the 14-inch bias-ply family, while the 1968 Plymouth Belvedere & Satellite w/426 Hemi V8 uses F70-15 on a 15-inch wheel.

That variation affects more than just the number printed on the sidewall. It changes wheel diameter, the available product assortment, and the sidewall styles you can choose from. A buyer looking for redlines or raised white letters, for example, may find those choices in one fitment and not another, so selecting the correct sub-model first keeps the search focused and accurate.

F70-15 is a bias-ply tire size on the 1968 Plymouth Belvedere & Satellite, specifically for the 426 Hemi V8 application. It uses the vintage alphanumeric bias-ply system rather than a modern metric radial format, and the available products in this primary fitment are classic bias-ply tires from Firestone and Goodyear.

That matters because a buyer may see F70-15 and assume it is simply a 15-inch tire category with broad interchangeability. In practice, it is the original-style construction and sizing format for that application. Anyone considering a radial alternative should compare the equivalent sizes separately and confirm wheel width, clearance, and overall setup before making the change.

Radial equivalents for F70-15 include 195R15 as the 80-series metric radial option, P205/75R15 as the 75-series P-metric radial option, P215/70R15 as the 70-series P-metric radial option, and 670R15 as the bias-look radial equivalent. The recommended rim-width range attached to these equivalents is 5-7 inches.

Each of those options reflects a different sizing convention and, in the case of 670R15, a more traditional visual presentation. None should be treated as an automatic substitute just because the rim diameter matches. The wheel width, the actual wheel on the car, and the available clearance around the fender and suspension all deserve a careful check before moving from the bias-ply size.

That depends on the role of the car and the exact look you want. The primary fitments on the 1968 Plymouth Belvedere & Satellite are all bias-ply sizes, so staying with bias-ply preserves the original-style sizing system and the traditional tire presentation. Radial equivalents are available for each primary size if a modern construction alternative is being considered.

The real decision is usually appearance and setup, not simply old versus new. A restoration-oriented car may call for the original-style bias-ply look, while a driver may lead the owner toward an equivalent radial. Either way, the change should be evaluated with the actual wheel dimensions, the car's current ride height, and available steering and body clearance in mind.

Start with the exact sub-model and correct primary size, because this Plymouth uses five different bias-ply fitments across the range. The next factors are wheel diameter, wheel width, and whether the goal is a period-style bias-ply tire or a carefully checked radial equivalent for that specific size.

Once the fitment is narrowed down, compare the choices that actually change the look and character of the car. On some sizes that means blackwall or narrow whitewall, while on others it may mean redline, goldline, pin-white-stripe, or raised white letter styling. Brand and tire series also become relevant once the correct size and wheel combination have been confirmed.

Sidewall choices for the 1968 Plymouth Belvedere & Satellite include blackwall, narrow whitewall, redline, goldline, pin-white-stripe, and RWL, which is raised white letter. The available style depends heavily on the tire size. Smaller 14-inch sizes lean toward blackwall and narrow whitewall, while F70-15 adds more muscle-era presentation options.

That difference can shape the car's appearance as much as the size itself. A wagon or standard 14-inch car may suit a restrained whitewall or blackwall, while the Hemi F70-15 fitment opens the door to redline, stripe, and raised white letter styles associated with late-1960s performance imagery. The best choice is the one that matches the vehicle's exact trim, stance, and restoration direction.

Tires for the 1968 Plymouth Belvedere & Satellite are available from BFGoodrich, Firestone, Goodyear, and US Royal, depending on the size. BFGoodrich covers much of the 14-inch numeric range, while Firestone and Goodyear are especially visible in the F70-15 muscle-era fitment, and US Royal appears in 775-14.

Brand matters most after the correct size has been established. Different brands may appear in different tire series and sidewall treatments, so the practical comparison is not only who makes the tire but which visual and fitment choices each brand offers in that exact size. That approach keeps the decision grounded in the car's actual application rather than broad brand preference.

A period-style choice starts with the original-size bias-ply fitment for the exact sub-model. On the 1968 Plymouth Belvedere & Satellite, that means selecting the correct 14-inch numeric bias-ply size or the F70-15 alphanumeric bias-ply size for the 426 Hemi V8 application, then choosing the sidewall treatment that best suits the car's intended presentation.

The strongest restoration result usually comes from matching size, wheel diameter, and sidewall style to the way the car is being finished, rather than choosing a popular style at random. If exact originality matters beyond a general period look, marque references, build documentation, and model-specific historical sources are the right places to confirm whether a particular sidewall treatment aligns with the car.

Tire construction affects both stance and visual character on a restored 1968 Plymouth Belvedere & Satellite. The primary fitments are bias-ply sizes, so a bias-ply tire preserves the vintage sizing language and traditional sidewall shape associated with the car's era. A radial equivalent can change the presentation even when the wheel diameter remains the same.

That does not automatically make one construction right and the other wrong. A buyer focused on an original-style or show-oriented look will often prefer the bias-ply presentation, while a driver may be more open to a radial equivalent. The best approach is to decide whether the restoration goal is visual authenticity, regular road use, or a balanced blend of both.

Yes. Modifications can change tire fitment on a 1968 Plymouth Belvedere & Satellite even when the intended tire size is otherwise correct. Aftermarket wheels, non-stock wheel widths, suspension changes, altered ride height, or brake upgrades can all affect how a 735-14, 825-14, or F70-15 tire sits in the wheel opening and around steering components.

That is especially important on a car with multiple original fitments and both 14-inch and 15-inch wheel applications. Before choosing a tire, compare the actual wheel diameter and width on the vehicle and look for any signs of rubbing history. A modified car should always be evaluated by its present setup, not only by the fitment it carried when new.

Before driving a 1968 Plymouth Belvedere & Satellite on new tires, inspect the wheels for the correct diameter and general condition, then confirm proper inflation and look for adequate clearance at the fenders, suspension, and steering range. It is also smart to check the wheel hardware, valve stems, and overall tire seating after installation.

Collector cars often spend long periods parked, so the first road test should be deliberate rather than rushed. A short, careful drive can reveal rubbing, vibration, or pull that was not obvious at rest. After that first outing, recheck air pressure and give the tires another visual inspection to make sure the fitment is settling in as expected.

Collector-car tires on a 1968 Plymouth Belvedere & Satellite should be inspected regularly for air loss, tread wear, sidewall cracking, cuts, bulges, and signs of aging from long storage. Maintaining correct inflation is important whether the car runs one of the 14-inch bias-ply sizes or the F70-15 fitment, since underuse can hide developing problems.

Storage conditions matter almost as much as mileage on a low-use Mopar. Keeping the car away from prolonged heat, direct sunlight, moisture, and ozone-producing equipment helps preserve the tires between drives. Even a car that looks freshly restored deserves routine tire checks, because age and storage can affect roadworthiness long before the tread appears worn out.
