1950 Pontiac Tire Fitment Guide

1950 Pontiac vehicles use two listed tire sizes: 7.10-15/6 and 710-15. The 7.10-15/6 size applies to the 1950 Pontiac 6 & 8 Cyl., Pontiac, and Sedan Delivery, while 710-15 is used on the 1950 Pontiac 6 & 8 Cyl. Both sizes are bias-ply fitments for 15-inch wheels, and the available 710-15 products are built for 5.00- to 5.50-inch rim widths.

That means year and make alone are not always enough to choose a tire for a 1950 Pontiac. If you have a 6 & 8 Cyl. car, verify which of the two listed sizes belongs on your exact application before moving on to sidewall style. If you have a Pontiac or Sedan Delivery, the choice is narrower and centers on keeping the correct 15-inch bias-ply format for the vehicle.

On a 1950 Pontiac, 710-15 is an older numeric bias-ply tire size. The 710 portion refers to the nominal section width in the traditional numeric system, and the 15 refers to the wheel diameter in inches. It is not a modern metric code, and it does not indicate a radial construction. For 1950 Pontiac applications here, 710-15 belongs specifically to the 6 & 8 Cyl. models.

That matters because a modern buyer may assume every 15-inch tire with a similar overall look is interchangeable, when the original size format still affects restoration accuracy and product selection. Once you know your Pontiac uses 710-15, the next step is choosing between blackwall and wide whitewall versions and confirming the wheel falls within the tire’s approved rim-width range.

No, not every 1950 Pontiac model in this group uses the same tire size. The 7.10-15/6 size is shared by the 6 & 8 Cyl., Pontiac, and Sedan Delivery, but 710-15 appears only on the 6 & 8 Cyl. line. All of these are 15-inch bias-ply applications, yet the exact size still changes by model grouping.

That makes model identification the first practical step before comparing brands or sidewall appearance. On a broad postwar lineup like 1950 Pontiac, body style, trim history, and previous restoration work can all complicate what is currently mounted on the car. Verifying the model and checking the actual wheel and existing tire markings will help you avoid choosing a size that is correct for the year but wrong for your specific Pontiac.

For 1950 Pontiac tires in the available 710-15 fitment, sidewall styles include blackwall and wide whitewall versions. BFGoodrich offers both blackwall and whitewall choices, while Firestone appears in blackwall form within the listed products. Those options stay within the same bias-ply construction, so the visual difference is in sidewall appearance rather than a change in basic tire type.

Sidewall style can dramatically change the look of a 1950 Pontiac, especially on a full-size postwar car where whitewalls were a major part of the period presentation. Buyers aiming for a cleaner, more restrained look often lean toward blackwall, while a broad whitewall better matches the upscale visual language many restorers want. The right choice comes down to your car’s presentation goals and the era-correct look you want to emphasize.

BFGoodrich and Firestone both offer tires for 1950 Pontiac vehicles in the listed 710-15 fitment. BFGoodrich appears in blackwall and wide whitewall versions, while Firestone appears in blackwall. All of the available products for that size are bias-ply tires built around the traditional construction style expected on an early-1950s American car.

Brand choice on a collector Pontiac usually comes down to the look you want on the car and how closely you want the finished vehicle to reflect period styling cues. Some owners prioritize a particular sidewall treatment, while others want a brand name that feels at home on a postwar American restoration. Once size is confirmed, comparing brands within that exact fitment is the right way to narrow the field.

For a 1950 Pontiac in 710-15, BFGoodrich and Firestone both offer bias-ply tires with the same listed load figure of 1550 pounds at 32 psi and the same 15-inch rim diameter with a 5.00- to 5.50-inch approved rim-width range. The main visible difference in the available lineup is sidewall presentation: BFGoodrich appears in blackwall and wide whitewall versions, while Firestone is listed in blackwall. Product weights also vary slightly among the options.

That means the decision is less about one tire having a fundamentally different fitment profile and more about how you want the car to look once mounted. If your Pontiac restoration calls for a bright, period-style whitewall, BFGoodrich gives you that path in this size. If a blackwall presentation better suits your build, both brands keep you within the correct general bias-ply character for the era.

For 1950 Pontiac tires in the listed 710-15 size, the approved rim-width range is 5.00 to 5.50 inches on a 15-inch wheel. That gives a clear wheel-width target for the available bias-ply products in that size. The year’s other listed size, 7.10-15/6, also fits a 15-inch wheel, but the key confirmed wheel-width range here is tied to the 710-15 product offerings.

Rim width matters because even when wheel diameter is correct, a wheel that is too narrow or too wide can affect how the tire sits, wears, and responds on the road. Before fitting a replacement tire to a 1950 Pontiac, measure the actual wheel or confirm it against a known factory-correct wheel. That is especially important on cars that may have had wheels changed during decades of repair or restoration.

The available 1950 Pontiac 710-15 products are listed without TT or TL markings in the size field, so tube status is not presented as a mixed set of tube-type and tubeless options within that fitment. These are traditional bias-ply collector tires intended for period-style applications, and tube use should be matched to the wheel design and the specific tire’s sidewall markings rather than assumed solely from size.

The practical step is to inspect the wheel itself before mounting tires on a 1950 Pontiac. Original-style wheels, riveted wheels, or older rims with surface condition issues may influence whether a tube setup is appropriate. If you are preserving factory-style wheels, confirm the tire’s marking and the wheel condition together instead of treating all 15-inch bias-ply products as interchangeable from a tube standpoint.

Both listed 1950 Pontiac sizes are 15-inch fitments, so they share the same wheel diameter. That means the original 15-inch wheels are within the correct diameter family for either size where that size belongs to the model. For the available 710-15 products, the approved rim-width range is 5.00 to 5.50 inches, which gives an important checkpoint beyond diameter alone.

Diameter compatibility does not automatically settle every fitment detail on a 1950 Pontiac. You still need to confirm that the wheel width matches the tire you plan to run and that the size itself is correct for your model. On a car that has lived through decades of service, replacement wheels may look original at a glance, so measuring the wheel is a smart final check before mounting.

A stored 1950 Pontiac should be kept out of direct sunlight and away from electric motors, battery chargers, welders, and other ozone-producing equipment that can accelerate sidewall aging. Bias-ply tires also tend to develop temporary flat spotting more readily during long static storage. Clean, dry concrete is better than damp ground, and keeping the tires properly inflated helps the casing hold its shape.

For a collector Pontiac that sits for extended periods, moving the car occasionally or using properly positioned stands can reduce stress concentration in one spot on the tread. Storage practices matter just as much as mileage on a low-use classic. A well-kept environment preserves both the appearance of a whitewall and the structural health of a blackwall bias-ply tire over time.

Tires on a 1950 Pontiac should be judged more by age and condition than by miles driven. A common collector-car guideline is to begin evaluating tires closely at around five to seven years of age and to give serious replacement consideration as they approach ten years, even if tread depth still looks usable. The DOT date code and the tire’s overall condition provide the most useful age reference.

That age-based approach is especially important on cars that see occasional drives, local shows, or seasonal use. A bias-ply tire can look presentable while still hardening with time, which affects how it behaves on the road. If your Pontiac has older tires with visible cracking, stiffness, or uneven aging, replacement deserves attention before the next touring season rather than after a problem appears.

Tires on a 1950 Pontiac should be checked before every drive and again before any longer outing. Look for sidewall cracking, bulges, cuts, embedded debris, uneven wear, and signs that the tire has been losing pressure. On a collector car, inspection should also include the valve stems and the spare, because age often affects those pieces even when the car is driven infrequently.

A brief walkaround can catch issues that are easy to miss when a car spends most of its life parked indoors. Long-distance drives place sustained heat and load into a tire, so a small defect that seems harmless in the garage can become a real problem on the road. Building inspection into every outing is one of the simplest ways to protect a vintage Pontiac and its occupants.

A 1950 Pontiac 6 & 8 Cyl. would have been fitted in the bias-ply era, so a bias-ply construction is the historically appropriate starting point for restoration work. The listed fitments for this model group are 7.10-15/6 and 710-15, both on 15-inch wheels. That aligns with what buyers expect on a mainstream American passenger car from 1950, before radial adoption became common in the U.S. market.

Original-equipment details could still vary by body style, market, or period service replacement history, so a factory manual, period sales literature, or Pontiac marque club can help settle the last layer of authenticity. For most restorers, the big authenticity checkpoints are staying with the correct size family, retaining bias-ply construction, and choosing a sidewall style that matches the way the car would have been presented in its era.

Correct tire fitment matters on a 1950 Pontiac because judged restoration standards often consider whether the size, construction type, and sidewall appearance suit the period and the specific car. A visibly modern format or an incorrect sidewall treatment can stand out quickly on an early-1950s American sedan or delivery body. Bias-ply construction is typically part of the visual and historical character expected for this year.

That does not mean every event applies the same level of scrutiny, but serious authenticity judging usually rewards getting the tire details right. If you plan to show your Pontiac, compare your chosen size and sidewall look against period photos and seek guidance from Pontiac club members familiar with the body style you own. That is often the easiest way to avoid a tire choice that looks good in isolation but feels out of place on the finished car.

On a 1950 Pontiac, blackwall and whitewall tires can share the same basic size and bias-ply construction while creating very different visual results. In the available 710-15 offerings, blackwall versions keep a simpler, more understated look, while wide whitewall versions add the bright sidewall treatment many enthusiasts associate with upscale postwar American styling. The change is primarily aesthetic rather than a shift to a different construction type.

Choosing between them usually depends on the story you want the finished Pontiac to tell. A whitewall can make a freshly restored car feel more formal and period-dressed, while a blackwall may better suit a more restrained restoration or a utility-oriented body such as a delivery model. For authenticity-minded owners, period photography and marque-club guidance are the best final references when deciding how prominent the whitewall should be.

A properly fitted, properly inflated 1950 Pontiac bias-ply tire in good condition can be used for normal road driving, but safe highway use depends on the full vehicle system as much as the tire itself. These Pontiacs come from an era of different braking, suspension, and steering behavior than a modern car, and bias-ply construction has its own feel in tracking and response. Highway confidence starts with condition, fitment, and realistic expectations for a 1950 chassis.

That means the smartest approach is to drive a 1950 Pontiac within the limits of both the tire and the vehicle rather than using modern-car habits as the benchmark. Before any sustained highway trip, check inflation, age, visible condition, wheel condition, and front-end health together. A vintage Pontiac with fresh tires but neglected steering or brake components is still not ready for the kind of speed and distance modern traffic may encourage.

For the available 1950 Pontiac 710-15 products, the listed maximum load figure is 1550 pounds at 32 psi. That number is the tire’s rated load-and-pressure pairing, not automatically the everyday running pressure for every 1950 Pontiac application. Factory operating pressure should be confirmed from Pontiac literature for your model, while the tire maker’s specifications should be observed for the reproduction tire you select.

The important point is not to transfer one pressure figure casually across every tire and every Pontiac model. Inflation affects ride quality, tread wear, and how a bias-ply car tracks on the road. Start with the guidance appropriate to your exact size and model, then verify that the wheel, the tire, and the intended use all line up before settling on the service pressure you plan to run.

Before a longer drive in a 1950 Pontiac, inspect each tire for cracking, cuts, bulges, tread separation, and uneven wear, then confirm inflation pressures when the tires are cold. Check valve stems, wheel condition, and the spare as well, since collector cars often carry an old spare that has not been evaluated in years. A longer trip also calls for a quick look at brake operation, steering play, and fluid condition.

A careful pre-drive routine is especially worthwhile on a postwar car that may spend much of its life parked between outings. Heat, sustained speed, and distance place more continuous stress on old components than a short local drive ever will. Treat the tires as one part of a full readiness check, because a well-preserved Pontiac is most enjoyable when the whole car is prepared for the trip, not just the tread.
