1948 Willys Jeep CJ-2A Tires

A 1948 Willys Jeep CJ-2A uses either a 600-16 or a 700-15 tire, and both are bias-ply sizes. The 600-16 belongs on a 16-inch rim, while the 700-15 belongs on a 15-inch rim. The CJ-2A Base can be found with either of these primary fitments.

The important next step is checking the actual wheel diameter on the Jeep before choosing a tire. Since these two sizes use different rims, the decision is not simply about tread or sidewall style. Once the wheel size is confirmed, the remaining choice becomes whether the Jeep is being set up with a more traditional passenger-car look, a military NDT style, or a truck-oriented tread pattern.

The 1948 Willys Jeep CJ-2A can use either a 16-inch rim with 600-16 tires or a 15-inch rim with 700-15 tires. Both fitments are part of the CJ-2A's primary bias-ply tire selection. Wheel diameter is the key detail that separates the two tire sizes.

A quick visual guess is not enough, especially on an older Jeep that may have had wheels changed over the years. Verifying the wheel itself helps avoid ordering the right-looking tire in the wrong diameter. Wheel width also matters once the rim diameter is confirmed, because some products in these sizes are intended for narrower rims while others allow a slightly broader range.

The 1948 Willys Jeep CJ-2A has more than one tire size because it appears with two primary wheel-and-tire combinations: 600-16 and 700-15. Both are bias-ply sizes, but they are built for different rim diameters. That means the difference is rooted in wheel setup rather than a simple alternative within the same rim size.

On a collector Jeep, wheel changes over time are common, so the size question should start at the rim rather than at the sidewall style. A buyer looking for a tall, narrow utility appearance may end up in a different tire family than someone working with a 15-inch wheel. Confirming the installed wheels also helps narrow the product search to the correct tread and sidewall choices.

Start with the fact that 600-16 is a bias-ply tire for a 16-inch wheel, so the wheel diameter and width need to match the tire's intended range. In this size, the CJ-2A has a broad mix of choices, including blackwall, wide whitewall, double-whitewall, military NDT, NATO-tread, and truck-style patterns.

That variety means the right pick depends on how the Jeep is being presented and used. A restoration-oriented civilian look points toward classic blackwall or whitewall bias-ply options, while a military-style or utility-focused setup may call for NDT or truck tread. Comparing rim-width guidance, load figures where stated, and overall tread character helps narrow the selection within the correct size.

1948 Willys Jeep CJ-2A tires are available in several sidewall styles, including blackwall, wide whitewall, and double-whitewall. Most of the military and truck-oriented patterns appear as blackwalls, while some of the more passenger-style bias-ply options in both 600-16 and 700-15 are offered with whitewall treatments.

Sidewall choice changes the Jeep's appearance more than many buyers expect, especially on an open-bodied utility vehicle with exposed wheels. A blackwall usually keeps the look more work-oriented or military-inspired, while a whitewall pushes the Jeep toward a more polished civilian presentation. The sidewall should be chosen after confirming the correct tire size, not before, since style availability differs by size and series.

Tires for the 1948 Willys Jeep CJ-2A are available from brands including Firestone, Goodyear, BFGoodrich, Coker Classic, Avon, STA, Camac, Lester, Excelsior, and Ford Script. Brand availability depends on whether the Jeep uses the 600-16 or 700-15 bias-ply size and on the type of tire being considered.

The practical comparison is less about ranking brands and more about matching the tire's character to the Jeep. Some options focus on classic passenger styling, some on military NDT presentation, and others on truck-oriented tread patterns. Once the correct wheel diameter and tire size are confirmed, brand can be used to narrow the field by preferred series, sidewall style, or load specification where it is stated.

A period-style 1948 Willys Jeep CJ-2A starts with using the correct primary bias-ply size for the wheels on the vehicle, either 600-16 or 700-15. From there, the choice usually comes down to the Jeep's intended presentation, with classic civilian-style blackwall or whitewall tires on one side and military or truck-pattern tires on the other.

Appearance and use should stay aligned. A Jeep being restored with a civilian, road-going look may suit a traditional bias-ply series, while a utility or military-inspired build may look more natural with NDT or other service-style tread. When exact originality matters beyond period style, marque references and restoration documentation are worth checking before settling on a brand or sidewall treatment.

On a restored 1948 Willys Jeep CJ-2A, construction affects appearance because both primary fitments are bias-ply, and that construction carries the narrow, upright profile most buyers associate with an early postwar Jeep. The tire's shape and tread style contribute heavily to whether the vehicle reads as civilian, military-inspired, or utility-focused.

Since the CJ-2A's fitment here stays within bias-ply choices, the visible differences come from tread pattern and sidewall treatment rather than from a switch to radial construction. A whitewall can give the Jeep a distinctly different presentation from a blackwall NDT. Matching the tire's visual character to the vehicle's restoration direction helps the finished Jeep look intentional rather than mixed in period cues.

Modifications can affect tire fitment on a 1948 Willys Jeep CJ-2A, especially if the Jeep has aftermarket wheels, changed wheel widths, altered suspension height, or body modifications. Since this model uses either 600-16 or 700-15 bias-ply tires, any change in wheel diameter or width can shift which tire size and product range make sense.

A CJ-2A that has been lifted, lowered, or fitted with non-original wheels should be checked for steering clearance, fender clearance, and wheel compatibility before new tires are chosen. Even when the sidewall size looks right, the actual wheel setup may not match the tire's intended rim range. That is especially important on old Jeeps that may have been adapted for farm, trail, or collector use over many decades.

Before driving a 1948 Willys Jeep CJ-2A on new tires, inspect the wheels for the correct diameter and sound condition, then confirm the tires are seated properly and inflated appropriately for the specific product. It also helps to check valve stems, lug hardware, and basic tread-to-body clearance with the Jeep sitting at normal ride height.

A short, careful initial drive is a good way to confirm that nothing rubs during steering or suspension movement. Collector Jeeps can have worn steering parts, uneven springs, or old wheel hardware that only show up once the vehicle is back on the road. Looking over the sidewalls and tread after the first few miles can catch contact marks or pressure-related issues early.

Tires on a collector 1948 Willys Jeep CJ-2A should be inspected regularly for cracking, cuts, bulges, uneven tread wear, and slow air loss, even if the Jeep is driven only occasionally. That matters for both 600-16 and 700-15 bias-ply tires, because long storage periods can hide age-related issues until the vehicle returns to road or trail use.

Storage conditions make a real difference on low-use collector vehicles. Keeping the Jeep away from prolonged sunlight, moisture, and ozone sources helps preserve the tires, and maintaining proper inflation reduces stress on the casing while parked. It is also smart to recheck pressure and overall condition before a longer outing, since an older Jeep often spends more time sitting than accumulating miles.
