The 1951 Pontiac Sedan Delivery came from an era when utility vehicles still carried real style, blending postwar Pontiac design with the cargo-carrying usefulness that made sedan deliveries popular for commercial duty and light hauling. Today, these vehicles appeal to restorers and collectors who want the look and stance of an early 1950s workhorse without losing the character that defines the body style. Tire fitment for the 1951 Pontiac Sedan Delivery centers on one primary size, 7.10-15/6, in a bias-ply construction on a 15-inch rim. That keeps the tire decision focused on maintaining the proper vintage presentation and confirming wheel condition, fitment, and overall road readiness before driving.
Which Tire Size Is Right for The 1951 Pontiac Sedan Delivery
The 1951 Pontiac Sedan Delivery uses one primary tire size: 7.10-15/6 in a bias-ply construction for a 15-inch rim. That fitment is shared across the covered 6 & 8 Cyl. version, so the main decision is less about choosing between sizes and more about staying with the proper vintage-style construction and verifying that the wheels and overall vehicle setup still match the original-style fitment.
The 7.10-15/6 size is a vintage numeric bias-ply designation, with the 7.10 figure indicating the tire's nominal section width in inches and the 15 indicating a 15-inch wheel diameter. On a 1951 Pontiac Sedan Delivery, that format reflects the kind of traditional fitment expected on an early 1950s utility vehicle, where ride height, sidewall profile, and overall appearance are closely tied to the bias-ply tire design. For a restoration-minded owner, this size keeps the focus on preserving period-style proportions rather than converting to a modern sizing system. It is also the right starting point for checking wheel condition, rim diameter, and vehicle readiness before returning the car to road use.
Fitment is straightforward for the covered 1951 Pontiac Sedan Delivery sub-model. The 6 & 8 Cyl. version uses the same primary tire size, which means tire selection comes down to choosing the right period-style replacement and confirming the actual wheel setup on the vehicle.

Frequently Asked Questions
These FAQs focus on the 1951 Pontiac Sedan Delivery tire size, 15-inch rim fitment, bias-ply construction, restoration-minded selection, and the wheel, suspension, and maintenance checks that matter before putting a low-use collector vehicle back on the road.
Tire Size & Fitment
What tire size fits a 1951 Pontiac Sedan Delivery?
The 1951 Pontiac Sedan Delivery uses a 7.10-15/6 tire size. This is a bias-ply fitment built for a 15-inch rim, and it is the primary size associated with the vehicle, including the covered 6 & 8 Cyl. sub-model.
That makes the first priority confirming that the car still has the correct 15-inch wheels and an original-style setup. On an older collector vehicle, wheels may have been changed over time, so checking actual rim diameter and overall tire clearance is just as important as matching the sidewall size marking.
What size rim does a 1951 Pontiac Sedan Delivery use?
The 1951 Pontiac Sedan Delivery uses a 15-inch rim with its 7.10-15/6 tire size. The tire and wheel pairing follows a traditional early 1950s bias-ply arrangement, so the 15-inch diameter is a central part of proper fitment.
Rim diameter should be verified at the wheel, especially on a vehicle that has gone through years of service, restoration, or modification. A tire marked for a 15-inch rim should not be treated as suitable for another wheel diameter, even if the overall appearance seems close at a glance.
Does the 1951 Pontiac Sedan Delivery 6 & 8 Cyl. use the same tire size?
Yes. The covered 1951 Pontiac Sedan Delivery 6 & 8 Cyl. uses the same 7.10-15/6 bias-ply tire size. That means there is no separate tire-size split within this sub-model grouping, which simplifies fitment selection.
Even with a shared size, it is still worth checking the actual wheels on the vehicle before ordering tires. Older sedan deliveries are often restored, stored for long periods, or updated with replacement wheels, so confirming rim diameter and general wheel condition helps prevent fitment surprises.
Choosing the Right Tire
What should I consider when choosing a 7.10-15/6 tire for a 1951 Pontiac Sedan Delivery?
Start with the size itself: a 1951 Pontiac Sedan Delivery uses 7.10-15/6 in a bias-ply construction on a 15-inch rim. The key decision is usually whether the goal is a restoration-oriented, period-style presentation or simply maintaining the proper vintage fitment and proportions for regular collector use.
Beyond the sidewall marking, inspect the actual wheel diameter and overall condition of the wheels before selecting a replacement. On a low-production survivor or restored vehicle, choices should also reflect how the car will be used, how closely the owner wants to preserve original-style appearance, and whether the suspension and clearance remain stock.
How do I choose between available 7.10-15/6 tires for a 1951 Pontiac Sedan Delivery?
The most important factor is staying with the correct 7.10-15/6 size and bias-ply construction for the 1951 Pontiac Sedan Delivery. Once the size and construction are correct, the next comparison points are usually appearance, intended use, and how closely the tire suits the character of a restoration or preserved utility vehicle.
A sedan delivery often looks best with a tire that maintains traditional sidewall shape and overall stance rather than chasing a more modern appearance. Wheel condition, storage history, and the vehicle's actual road use matter too, since a show-focused vehicle and a regularly driven collector vehicle may call for different priorities within the same size.
What rim-fitment details should I compare when choosing 1951 Pontiac Sedan Delivery tires?
The first rim-fitment detail to confirm is diameter, because the 1951 Pontiac Sedan Delivery uses a 15-inch wheel with its 7.10-15/6 bias-ply tire. That should be verified directly on the vehicle rather than assumed, especially if the wheels have been refinished, replaced, or reused from another period car.
It also helps to inspect the wheel's general condition, bead area, and overall straightness before mounting new tires. Collector vehicles that have sat for years can have rust, damage, or age-related wheel issues, and those problems can affect mounting quality, air retention, and safe road use even when the tire size itself is correct.
Restoration & Appearance
Which tire should I choose for a period-style 1951 Pontiac Sedan Delivery?
A period-style starting point for the 1951 Pontiac Sedan Delivery is the original-type 7.10-15/6 bias-ply fitment on a 15-inch rim. That sizing and construction preserve the tall-sidewall, vintage utility-vehicle character that suits an early 1950s sedan delivery far better than a modern-looking replacement approach.
For a restoration-oriented vehicle, tire choice affects stance and visual balance as much as it affects drivability. Owners aiming for exact historical accuracy should compare their selection against marque references, period photography, and restoration documentation, while still confirming that the present-day wheels and chassis remain compatible with the intended tire.
Does correct tire fitment matter for a 1951 Pontiac Sedan Delivery restoration?
Yes, correct tire fitment matters noticeably on a 1951 Pontiac Sedan Delivery because the vehicle's proportions depend heavily on a proper early 1950s bias-ply tire shape. Using the correct 7.10-15/6 size helps preserve the visual character, ride height impression, and traditional stance expected of a sedan delivery from this period.
Appearance is only part of the equation. Correct fitment also helps avoid avoidable clearance or wheel-matching problems that can complicate a restoration after the tires are mounted. On an older project, it is smart to verify the actual wheels, suspension condition, and any prior modifications before committing to a final tire choice.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1951 Pontiac Sedan Delivery?
Yes. Modifications can affect tire fitment on a 1951 Pontiac Sedan Delivery even when the intended tire size remains 7.10-15/6. Changes such as aftermarket wheels, altered ride height, replacement springs, brake conversions, or bodywork repairs can all influence how a tire sits within the wheel opening and how it clears during steering and suspension movement.
A sedan delivery that appears stock may still have changes made decades ago, so actual inspection matters more than assumption. Checking wheel diameter, wheel condition, and visible clearance at the fender and suspension points helps confirm that a proper bias-ply replacement still suits the vehicle as it exists today.
What should I inspect before driving a 1951 Pontiac Sedan Delivery on new tires?
Before driving a 1951 Pontiac Sedan Delivery on new tires, inspect the wheels, lug hardware, valve stems, and overall mounting condition in addition to the tires themselves. It also makes sense to check for visible suspension wear, steering looseness, and any signs that the vehicle has sat long enough for age-related issues to develop.
Collector vehicles often spend extended periods parked, which can hide problems unrelated to the new tires. Tire pressure, sidewall condition, tread condition, and air retention should be checked after installation, and a short local test drive is a sensible way to confirm that the vehicle tracks properly before taking a longer trip.
How should 7.10-15/6 tires on a collector 1951 Pontiac Sedan Delivery be maintained?
7.10-15/6 tires on a collector 1951 Pontiac Sedan Delivery should be maintained with regular pressure checks, visual inspection, and careful storage habits. Because older collector vehicles may be driven infrequently, tire condition can decline from age and environment even when tread wear remains minimal.
Look for cracking, bulges, cuts, or persistent air loss, and inspect the tires before each meaningful road outing rather than relying on mileage alone. Storage away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, while periodic wheel and suspension checks support better long-term service from the complete setup.
