1987 GMC Vans G2500 Tires

The 1987 GMC Vans G2500 uses two primary tire sizes: 225/75R15 and 235/75R15. Both are radial tires mounted on 15-inch wheels, but the exact size depends on the sub-model. The Rally with a 6600 GVWR uses 225/75R15, the Rally with a 6850 GVWR uses 235/75R15, and the Vandura can appear with either size.

That means the first step is not choosing a brand or sidewall style, but confirming which G2500 version you have and checking the wheel setup currently on the van. A Vandura deserves extra attention because both primary sizes are associated with it. Matching the tire size to the van's exact configuration helps avoid problems with appearance, load-related specs, and overall fitment.

Both tire sizes used on the 1987 GMC Vans G2500 are built for 15-inch rims. Whether the van uses 225/75R15 or 235/75R15, the wheel diameter remains the same, so the size difference is in the tire dimensions rather than a change to a different wheel diameter.

Wheel diameter is only part of the fitment picture, so it is still wise to confirm wheel width before settling on a tire. Product options in these sizes show different approved rim-width ranges, and that matters when a van has replacement wheels. A 15-inch rim is necessary, but the actual wheel width and the van's current setup should still be checked.

More than one tire size appears on the 1987 GMC Vans G2500 because fitment varies by sub-model and weight classification. The two Rally versions separate by GVWR, with one using 225/75R15 and the other using 235/75R15. The Vandura also spans both sizes, which makes it the most important version to verify carefully.

This is common on full-size vans that were sold in different passenger and utility configurations. A buyer should confirm the exact sub-model and compare the van's existing wheel-and-tire combination before choosing between the two sizes. That keeps the decision grounded in the van's actual fitment instead of assuming every G2500 was built around the same tire.

Start with the correct primary size for the van, since the 1987 GMC Vans G2500 uses either 225/75R15 or 235/75R15 depending on configuration. From there, compare radial construction details such as approved rim-width range, maximum load figures at the stated pressure, sidewall treatment, and the overall character of the tire series offered in that size.

A restoration-minded van may lean toward a whitewall presentation, while a utility-focused setup may point toward a different style within the correct size. Wheel width matters, especially on vans that may have had wheels changed over the years. It also helps to think about how the van is driven now, since occasional cruising and heavier-duty use can shape which product characteristics matter most.

Sidewall choices for the 1987 GMC Vans G2500 include wide whitewall, narrow whitewall, and raised white letter styles, depending on tire size and product line. The 225/75R15 options focus on whitewall treatments, while 235/75R15 expands the appearance range with both whitewall choices and a raised white letter BFGoodrich all-terrain option.

That gives the van owner room to match the tire's look to the vehicle's presentation. A conversion van, cruiser, or restoration-themed build may call for a whitewall, while a more utility-oriented or truck-flavored setup may suit raised white letters. Appearance should still come after confirming the correct size and wheel compatibility, especially when comparing products across the two primary fitments.

Tires for the 1987 GMC Vans G2500 are available from BFGoodrich, Coker Classic, American Classic, Maxxis, Travelstar, and Tornel, depending on size. Those brands appear across the two primary 15-inch radial fitments, with several tire series and sidewall styles represented rather than one uniform product type.

Brand choice is best treated as one part of a broader comparison. The more useful approach is to first confirm whether the van needs 225/75R15 or 235/75R15, then compare the available brands by sidewall style, tire series, rim-width compatibility, and load-related specifications. That keeps the selection process centered on fitment and intended use instead of choosing by name alone.

A period-style 1987 GMC Vans G2500 usually starts with choosing the correct primary size first, then selecting a radial tire that suits the van's visual character. Whitewall options are widely available in both 225/75R15 and 235/75R15, with choices from American Classic, Coker Classic, BFGoodrich, Maxxis, Travelstar, and Tornel depending on the size.

The best appearance match depends on whether the van is being presented as a passenger Rally, a Vandura cruiser, or a more utility-focused build. Whitewall width can change the overall look noticeably, so compare that detail carefully. If exact originality matters, it is wise to cross-check the van's historical presentation with marque references and the wheel setup currently on the vehicle.

For the 1987 GMC Vans G2500, primary fitment stays within radial construction, so the visual differences come more from sidewall style and tire series than from a bias-ply-versus-radial decision. In practical terms, the restored look is shaped by whether the van carries a wide whitewall, narrow whitewall, or raised white letter sidewall in the correct size.

That makes appearance planning more straightforward than on earlier vehicles that straddle two construction eras. A whitewall can push the van toward a more dressed, conversion-era look, while raised white letters create a more truck-like presentation. Because these choices can change the personality of the vehicle, it helps to choose the sidewall style only after the proper size and wheel compatibility are settled.

Yes, modifications can affect tire fitment on a 1987 GMC Vans G2500 even when the tire size itself is one of the correct primary options. Changes such as aftermarket wheels, altered wheel width, suspension work, lowering, or body modifications can influence clearance and how a 225/75R15 or 235/75R15 tire sits on the van.

That is especially important on the Vandura, since both primary sizes are associated with that sub-model. A van that no longer carries its original wheel setup should be measured rather than assumed. Checking wheel diameter, wheel width, steering clearance, and fender space before ordering helps keep a correct-size tire from becoming the wrong fit for the van's current condition.

Before driving a 1987 GMC Vans G2500 on new tires, inspect the wheels, confirm the installed size matches the van's configuration, and make sure air pressure is set appropriately for the tire being used. It also makes sense to check lug hardware, valve stems, and general suspension condition so the new tires are not being asked to compensate for unrelated mechanical issues.

A short road test should be paired with a look at steering response, clearance at full lock, and any sign of rubbing or uneven stance. On an older full-size van, worn steering or suspension parts can show up quickly once fresh tires are installed. Catching those issues early helps protect the new tires and makes road use more predictable.

Collector-use tires on a 1987 GMC Vans G2500 should be checked regularly for pressure, tread condition, sidewall cracking, bulges, cuts, and signs of slow air loss. Because these vans may spend long periods parked, condition matters just as much as tread depth. Both 225/75R15 and 235/75R15 tires benefit from routine visual inspection even when mileage stays low.

Storage habits also play a role in how well the tires age over time. Keeping the van away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve appearance and serviceability. It is also smart to inspect the tires before longer drives rather than assuming a low-use van is automatically road-ready after sitting.
