1949 Hudson 491 & 492 Series Tires

The 1949 Hudson 491 & 492 Series uses two primary tire sizes: 710-15 and 760-15. Both are bias-ply tire sizes built for 15-inch rims, and the covered 6-cylinder sub-model is associated with both sizes rather than just one.

That makes wheel confirmation especially important before replacing the tires. A Hudson that still has its original-style wheel setup may differ from one that has had wheel changes over the years, so the safest next step is to verify the wheel width, confirm the size already on the car, and then choose the appropriate bias-ply tire or a carefully checked radial equivalent.

Both primary tire sizes for the 1949 Hudson 491 & 492 Series use a 15-inch rim diameter. That applies to 710-15 and 760-15, so the key rim measurement is the same even though the two tire sizes differ in section width.

Rim diameter alone is not the whole fitment story on a collector car of this age. Wheel width should also be checked, especially because the available 710-15 and 760-15 products are associated with different rim-width ranges, and many older vehicles have had wheel swaps during restoration or regular service life.

The 1949 Hudson 491 & 492 Series is associated with both 710-15 and 760-15, so more than one primary tire size falls within the covered fitment. Both are 15-inch bias-ply sizes, but they represent different nominal widths within the same vintage sizing system.

For the owner, that means the decision is not just picking any 15-inch tire that looks close. The practical step is determining which wheel width is on the car and whether the current setup is consistent with the narrower 710-15 or the wider 760-15 before choosing among blackwall, narrow whitewall, wide whitewall, or radial-equivalent alternatives.

On the 1949 Hudson 491 & 492 Series, 710-15 is a primary bias-ply tire size. It uses the traditional vintage numeric sizing format rather than a modern radial designation, which is why its appearance and construction suit a period-style postwar presentation.

That matters if the goal is to keep the Hudson's original-era look and driving character. Owners considering a change in construction can look at radial equivalents, but the move should be treated as a fitment decision rather than a simple label change, with attention paid to wheel width, tire dimensions, and available clearance.

For 710-15, radial equivalents include 205R15, P215/75R15, P225/70R15, and the bias-look 710R15. For 760-15, the equivalent sizes are 215R15, P225/75R15, P235/70R15, and the bias-look 760R15.

These options cover several sizing conventions, from Euro-metric 80-series radials to P-metric 75-series and 70-series alternatives, plus a radial designed to keep a more traditional visual profile. They should be considered as radial equivalents rather than automatic replacements, so wheel width, overall stance, and fender and steering clearance all deserve a careful check first.

Start by confirming which original size the car uses, since the 1949 Hudson 491 & 492 Series is associated with both 710-15 and 760-15. Then match the conversion to the correct equivalent group and verify that the wheel setup is appropriate for the radial size under consideration.

A careful conversion review should include rim width, overall tire dimensions, steering clearance, suspension condition, and body or fender space. Bias-look radials such as 710R15 and 760R15 can help preserve a traditional appearance, while metric and P-metric choices change the sizing format and may alter how the tire fills the wheel opening.

The first consideration is getting the correct primary size for the wheel on the car, since this Hudson uses either 710-15 or 760-15 and both are bias-ply tires for 15-inch rims. After size, the main selection factors are wheel-width compatibility, sidewall treatment, brand, and tire series.

A restoration-minded Hudson owner may focus on keeping a traditional bias-ply appearance, while a driver planning more road miles may also compare radial-equivalent routes. It also helps to look at practical details such as load figures where available, weight differences between products, and whether the visual goal is blackwall, narrow whitewall, or wide whitewall.

The available sidewall styles for this Hudson include blackwall, narrow whitewall, and wide whitewall, depending on the tire size and product selected. The broadest variety appears in 710-15, while 760-15 focuses more heavily on whitewall presentations, with both narrow and wide whitewall options.

Sidewall choice has a major effect on how a late-1940s car looks even when the tire size remains the same. A blackwall gives a simpler, understated presentation, while the whitewall options create a more dressy postwar look, so the right choice usually depends on whether the car is being preserved as a driver, a restoration project, or a period-style cruiser.

Tires for the 1949 Hudson 491 & 492 Series are available from BFGoodrich, Firestone, Goodyear, US Royal, Coker Classic, and Universal Vintage Tire. The exact brand mix depends on whether the car uses 710-15 or 760-15, but both primary sizes have multiple brand choices in bias-ply construction.

Brand should be compared alongside size, sidewall style, tire series, and wheel compatibility rather than treated as the only decision point. A buyer looking at the product grid can use brand as one filter, then narrow the options by the appearance desired on the Hudson and by the rim-width range tied to the selected tire size.

A period-style approach starts with the correct primary fitment family: 710-15 or 760-15 in bias-ply construction on a 15-inch rim. That keeps the Hudson in the vintage numeric sizing system that suits the car's late-1940s design and preserves the traditional visual relationship between tire, wheel, and body.

From there, the decision usually comes down to sidewall presentation and overall stance. Whitewall options often complement the era especially well, while blackwalls offer a simpler look, and owners pursuing strict historical accuracy should compare the car against marque references, restoration photos, or other vehicle-specific documentation before settling on a final sidewall treatment.

Tire construction changes more than the way the car drives; it also affects the visual character of a restored 1949 Hudson 491 & 492 Series. A bias-ply tire keeps the car in its original-era construction style, while a modern radial can shift the overall look even when the tire occupies a similar size range.

Owners who want a traditional presentation often stay with bias-ply or look at a bias-look radial such as 710R15 or 760R15. That approach can preserve more of the vintage appearance than a modern metric-style sidewall, but wheel width and vehicle clearance still need to be confirmed before treating any radial equivalent as a workable alternative.

Yes, modifications can affect tire fitment on a 1949 Hudson 491 & 492 Series, even when the tire size appears correct on paper. Wheel swaps, suspension changes, lowering, brake conversions, or body repairs can all influence whether a 710-15, 760-15, or radial equivalent has the right space and wheel support.

That is why an older Hudson should be checked as it sits today rather than judged only by model-year fitment. Measuring wheel diameter and width, then checking steering lock, fender clearance, and the condition of springs and suspension components, helps prevent choosing a tire that matches the designation but not the actual vehicle setup.

Before road use, inspect the wheel condition, verify lug hardware, and confirm that the chosen tire size matches the car's actual wheel setup. It also makes sense to check alignment-related wear points, suspension condition, and whether the tire clears the body and steering components through the full range of motion.

A collector car that has been sitting deserves a second look after the first short drive as well. Tire pressure, bead seating, signs of rubbing, and any unusual pull or vibration should be reviewed early, especially on a 1949 Hudson where age, restoration history, and long-term storage can all affect how a fresh set of tires behaves.

Collector-car tires in 710-15 or 760-15 sizing should be maintained with regular pressure checks, routine visual inspection, and careful storage habits. Even on a low-mileage Hudson, look for cracking, cuts, bulges, uneven wear, and slow air loss, since age and inactivity can matter as much as tread depth.

Proper storage also helps preserve both function and appearance. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources can reduce premature aging, and moving or driving the vehicle periodically helps avoid long-term flat spotting, especially with bias-ply construction on a large postwar sedan like the 1949 Hudson 491 & 492 Series.
