1949 Pontiac Tire Fitment Guide

1949 Pontiac vehicles use two 15-inch bias-ply tire sizes: 7.10-15/6 and 710-15. The 7.10-15/6 size applies to the 1949 Pontiac 6 & 8 Cyl., Pontiac, and Sedan Delivery, while 710-15 is listed for the 1949 Pontiac 6 & 8 Cyl. only. For the 710-15 products, the approved rim width range is 5.00 to 5.50 inches, and the listed wheel diameter is 15 inches.

That means year and make alone are not quite enough to choose a tire for every 1949 Pontiac. If you own a Pontiac or Sedan Delivery, your path is straightforward around 7.10-15/6, but a 6 & 8 Cyl. car needs a closer look at the existing wheels and tire markings before you settle on a size. Checking the tire already on the car, the wheel itself, and any factory literature or marque references will usually sort out which 15-inch fitment belongs on your specific Pontiac.

On a 1949 Pontiac, 7.10-15/6 is a period numeric bias-ply tire size. The 7.10 portion identifies the nominal section width, 15 is the wheel diameter in inches, and the /6 suffix reflects a period load-ply designation rather than a modern aspect ratio. It is a tall-sidewall construction typical of late-1940s American cars and utility-based derivatives.

That code matters because it helps separate a true period-style fitment from later sizing systems that look similar but measure differently. If your 1949 Pontiac uses 7.10-15/6, you are dealing with a traditional bias-ply format suited to owners who want the car to sit and present the way a postwar Pontiac should. It is also a reminder not to confuse the final number with tread width or overall tire diameter, since the 15 refers specifically to wheel diameter.

No, not all 1949 Pontiac models use the same tire size. The shared size across the range is 7.10-15/6, which appears on the 6 & 8 Cyl., Pontiac, and Sedan Delivery, but the 6 & 8 Cyl. model line also appears with 710-15. Both sizes are bias-ply and both mount on 15-inch wheels, yet they are still separate fitment choices.

That distinction is important because a buyer can easily assume all late-1940s Pontiacs were identical in tire sizing when they were not. If you are working on a 1949 Pontiac 6 & 8 Cyl. car, confirm what is actually on the wheel now and whether the car is being restored to a specific factory configuration. On the other two models, the fitment path is simpler, since the listed size does not branch into a second option.

The right choice for a 1949 Pontiac depends first on the model and wheel setup, not on a preference between two different constructions, because both listed sizes are bias-ply. The 7.10-15/6 size is shared across the broader model range, including Pontiac and Sedan Delivery, while 710-15 is tied specifically to the 6 & 8 Cyl. line. Both preserve the road feel and visual character expected from a late-1940s Pontiac.

If your Pontiac is a 6 & 8 Cyl. car, the decision comes down to identifying which size belongs on your exact vehicle before comparing whitewall or blackwall appearance. If your car is a Pontiac or Sedan Delivery, the fitment is more direct around 7.10-15/6. In either case, use the existing tire marking, wheel measurement, and restoration intent together rather than treating the two sizes as interchangeable simply because both are 15-inch bias-ply tires.

1949 Pontiac tires in the 710-15 size are available in blackwall and wide whitewall styles. BFGoodrich offers both blackwall and wide whitewall versions, while Firestone appears in blackwall form within the listed assortment. Those sidewall treatments fit squarely within the visual language of a late-1940s American car, where whitewalls could dramatically change the car's overall presentation.

Choosing between them is usually an appearance and authenticity decision rather than a fitment one. A blackwall often suits a more restrained or working-car look, while a wide whitewall better matches the dressed-up postwar style many restorers want on a Pontiac passenger car. If the goal is event judging or a faithful period look, compare the sidewall style to period photos, sales literature, and marque-club guidance for your body style and market presentation.

BFGoodrich and Firestone both make tires for 1949 Pontiac vehicles in the 710-15 size. BFGoodrich appears in blackwall and wide whitewall versions, while Firestone is represented in blackwall form. Both are longstanding American names that look at home on a domestic postwar car and are offered here in bias-ply construction rather than in a modern radial replacement format.

Brand choice on a 1949 Pontiac usually comes down to the look you want and how closely you are trying to match a certain restoration style. Some owners prioritize a specific sidewall treatment, while others care more about brand heritage and visual consistency across a full restoration. Once the size is confirmed, compare the available whitewall width, sidewall appearance, and any posted load details to decide which version best matches your Pontiac's intended presentation.

The listed 710-15 tires for 1949 Pontiac applications fit 15-inch rims that are 5.00 to 5.50 inches wide. That rim width range is repeated across the available BFGoodrich and Firestone 710-15 bias-ply products, so there is a consistent setup target for that size. The wheel diameter is 15 inches, which aligns with the tire code itself.

Rim width matters because even when the tire size code looks correct, the tire still needs to sit on a wheel within its approved range to maintain the intended profile and bead seating. Before fitting a 710-15 tire to a 1949 Pontiac, measure the actual wheel rather than relying on assumptions about what should be there. On a restored or long-owned car, replacement wheels and old service changes are common enough that a quick measurement is worth the effort.

The listed tire sizes for 1949 Pontiac vehicles both mount on 15-inch wheels, so wheel diameter compatibility is shared. That makes it possible for original 15-inch Pontiac wheels to align with either size at the diameter level, provided the wheel itself is correct for the application and the tire's approved rim-width range is respected. Diameter alone, however, does not make the two sizes automatically interchangeable on every car.

A 1949 Pontiac owner should treat this as a wheel-confirmation question rather than a shortcut. Start by verifying that the car still carries the proper original-style 15-inch wheels, then check the wheel width and the size already fitted or specified for that model. That approach is especially useful on 6 & 8 Cyl. cars, where both 7.10-15/6 and 710-15 appear, because it keeps a restoration from drifting into a tire choice that looks plausible but is not actually correct for the vehicle.

A stored 1949 Pontiac should be kept in a cool, dry, dark environment away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that accelerate rubber aging. Bias-ply tires like those used on 1949 Pontiac applications are especially prone to temporary flat-spotting when they sit for long periods in one position. Clean floors, stable temperatures, and proper inflation all help reduce stress on the casing during storage.

Owners who store a 1949 Pontiac for months at a time should move the car periodically or place it on stands in a way that protects both the suspension and the tires, depending on the broader storage plan. If the car remains on the ground, rolling it occasionally helps change the contact patch. Good storage habits preserve appearance as much as function, which matters on a collector Pontiac where sidewall condition and period-correct presentation are part of the car's appeal.

Tires on a 1949 Pontiac should be judged more by age and condition than by mileage, because collector cars often accumulate very few miles while the rubber still continues to age. A sensible rule is to begin careful evaluation around the five- to seven-year mark and to give serious replacement consideration as a tire approaches ten years from its DOT date code, even if tread depth still looks serviceable. Heat, sunlight, storage conditions, and inflation history all affect lifespan.

That approach is especially important on a postwar car because an old-looking but little-used tire can still have internal aging that is not obvious at first glance. If your 1949 Pontiac is driven only to shows or on occasional weekend outings, calendar age remains the key factor. Keeping a record of installation date, storage conditions, and inspection results makes it easier to decide when a tire has aged out of safe road use even though the car itself spends much of its life parked.

Tires on a 1949 Pontiac should be inspected before every drive and given a more thorough check before any longer outing. Look for sidewall cracking, tread separation, bulges, uneven wear, embedded debris, and signs that the tire has lost pressure while parked. On a collector car, long idle periods can hide problems that would show up sooner on a daily driver.

A quick pre-drive walkaround is often enough to catch the issues that matter most, especially if the car has been sitting in one spot for weeks. For a 1949 Pontiac that appears at shows or takes occasional road trips, add a closer inspection of valve stems, the spare tire, and the general condition of the wheel and bead area. Frequent checks matter because age-related deterioration in an older bias-ply tire can progress quietly between drives.

A 1949 Pontiac 6 & 8 Cyl. would originally have been fitted with bias-ply tires, because that was the standard construction for American passenger cars in this period. The sizes associated here with that model family are 7.10-15/6 and 710-15, both mounted on 15-inch wheels. No specific original-equipment brand should be assumed without factory literature or marque-specific confirmation for the exact body style and market version.

For a restoration, the key point is that bias-ply construction is part of the correct visual and driving character for a 1949 Pontiac. Once the exact size for your car is confirmed, details such as blackwall versus wide whitewall become the next layer of authenticity. If you are restoring to judged standards, period brochures, Pontiac club references, and surviving unrestored examples are the right way to pin down which sidewall treatment best matches your particular 6 & 8 Cyl. car.

Correct tire fitment matters a great deal when showing a 1949 Pontiac because judges and knowledgeable enthusiasts often notice size, construction, and sidewall style immediately. A late-1940s Pontiac shown for authenticity should present with period-appropriate bias-ply tires in the correct size for the model, and an incorrect sidewall treatment can stand out just as much as an incorrect construction type. Tires influence stance, wheel opening fill, and the overall visual tone of the car.

That does not mean every event judges tires by the same standard, but it does mean they are one of the easiest details to get right before the car ever reaches the field. A 1949 Pontiac restored as a formal passenger car may call for a different visual emphasis than a Sedan Delivery with a more utilitarian character. Checking event rules and Pontiac-club guidance ahead of time helps you choose a tire that supports the restoration rather than quietly undermining it.

For the 1949 Pontiac in 710-15, BFGoodrich and Firestone are both available in bias-ply construction with the same listed load rating of 1550 pounds at 32 psi and the same 15-inch rim diameter. The listed rim-width range is also the same at 5.00 to 5.50 inches. The clearest difference in the available assortment is appearance: BFGoodrich is offered in blackwall and wide whitewall versions, while Firestone appears here in blackwall form.

That means the real comparison is less about fitment limits and more about the look you want on the car. If your 1949 Pontiac restoration calls for a whitewall presentation, BFGoodrich gives you that path in this size. If a blackwall suits the build better, either brand stays within the same broad setup envelope, so the decision can focus on visual preference and how the tire complements the style of your particular Pontiac.

1949 Pontiac tires can be suitable for highway driving when they are the correct size, properly mounted, correctly inflated, and in sound age and condition. The listed 710-15 products are bias-ply tires, and no separate modern speed-letter ratings are shown within this assortment. On a car of this era, the condition of the tire matters, but so do the vehicle's brakes, steering, suspension, and overall roadworthiness.

A 1949 Pontiac should be driven with the expectations appropriate to a late-1940s automobile rather than to a modern sedan. Bias-ply tires deliver the period-correct feel the chassis was designed around, but they also benefit from careful setup and sensible speeds. Before regular highway use, make sure the full car is sorted mechanically and that the tires are free from age cracking, damage, and long-storage deterioration, because road safety comes from the whole system working together.

The listed 710-15 tires for 1949 Pontiac vehicles carry a maximum load rating of 1550 pounds at 32 psi. That figure is the tire's rated load-and-pressure reference, not automatically the exact operating pressure every 1949 Pontiac should run at in every driving condition. Actual vehicle pressure settings should follow the original Pontiac recommendation when available and remain appropriate to the tire's own published limits.

The practical takeaway is to avoid borrowing a pressure figure from another size, another brand, or another collector car just because the wheels look similar. Start with the vehicle recommendation and then confirm that your chosen tire's maximum rated pressure is not being exceeded. A carefully set pressure helps a 1949 Pontiac ride, steer, and wear more consistently, while overinflation or underinflation can compromise both appearance and road behavior on a bias-ply setup.

Before a longer drive in a 1949 Pontiac, inspect each tire for cracks, cuts, bulges, exposed cords, unusual wear, and proper inflation, then check the spare as well. Since these applications are bias-ply and the car may sit for long periods, pay extra attention to age-related sidewall issues and any flat-spotting that does not disappear after a short drive. A wheel and tire check should be part of a broader look at brakes, fluids, lights, and steering.

Longer outings are when an older collector car stops being a static display and starts asking the full chassis to work for sustained time and heat. A few extra minutes spent on tire condition can prevent the most common age-related problems from interrupting the drive. For a 1949 Pontiac, that means treating the tire inspection as one part of a complete pre-trip routine rather than assuming a car that looked fine at the last show is automatically ready for distance.
