The 1989 Chevrolet Vans G20 sits in the era when full-size Chevrolet vans served everything from family travel to commercial duty, with long-lived boxy styling and a wide range of uses that still make them practical collector vehicles today. Tire choice on this model centers on two 15-inch radial sizes, 225/75R15 and 235/75R15, with fitment varying by sub-model. That makes the first decision less about vintage bias-ply versus radial conversion and more about confirming the exact van configuration and wheel setup already on the vehicle. From narrow and wide whitewalls to raised white letter options, the available tires also let owners balance period-style appearance with real-world road use.
Which Tire Size Is Right for The 1989 Chevrolet Vans G20
The 1989 Chevrolet Vans G20 uses two primary tire sizes, and both are radial tires designed for 15-inch rims. The key step is identifying the exact sub-model, because some G20 versions use 225/75R15 while others use 235/75R15, and one Chevy Van configuration can use either size. Once that is confirmed, the decision shifts to sidewall style, brand, tire series, and whether the van is being kept in a more restoration-oriented look or set up for everyday driving.
225/75R15 is a metric radial size in which 225 identifies the section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and 15 is the wheel diameter in inches. On the 1989 Chevrolet Vans G20, this size is part of the primary radial fitment and suits owners who need the correct 15-inch tire format for covered sub-models. Available choices include BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar, with narrow and wide whitewall treatments. This size is worth evaluating when the van is staying close to a traditional full-size van appearance while still using a modern radial construction.
235/75R15 follows the same metric radial sizing system, with a 235-millimeter section width, a 75-series profile, radial construction, and a 15-inch rim diameter. For the 1989 Chevrolet Vans G20, this is the larger of the two primary fitments and appears on specific sub-models as well as one Chevy Van application that can use either size. Product selection is broader here, with options from BFGoodrich, American Classic, Coker Classic, Maxxis, Tornel, and Travelstar in wide whitewall, narrow whitewall, and raised white letter form. This size deserves a closer look when wheel compatibility, intended stance, and the van's actual configuration all support the wider fitment.
Sub-model fitment matters on the 1989 Chevrolet Vans G20 because tire size is not the same across every version. Some covered sub-models stay with one radial size, while the Chevy Van range can overlap, so confirming the exact model designation and existing wheel setup is the smart place to start.

1989 Chevrolet Vans G20 Beauville
The 1989 Chevrolet Vans G20 Beauville uses a single primary radial tire size, which keeps selection more straightforward than some other G20 variants. Once that size is confirmed on the van, the main choice becomes sidewall appearance, brand preference, and whether the tire will support a more family-cruiser or restoration-oriented presentation.
The 1989 Chevrolet Vans G20 Chevy Van can use either of the two primary radial sizes, making this the most configuration-sensitive G20 sub-model in the group. Tire selection starts with confirming which 15-inch wheel and tire combination is actually on the van before comparing whitewall, raised white letter, or tire series differences.
The 1989 Chevrolet Vans G20 Chevy Van (LH6 Option) uses the larger primary radial size in this fitment group. That makes product comparison more about choosing among available brands, sidewall styles, and series within that size rather than deciding between multiple primary fitments.
The 1989 Chevrolet Vans G20 Sportvan uses one primary radial size, which simplifies the basic fitment question. After size is settled, the useful comparison points are tire appearance, rim-width compatibility, and whether the van is being equipped for regular road use or a more period-style look.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Common 1989 Chevrolet Vans G20 tire questions usually come down to the correct size by sub-model, 15-inch rim fitment, whitewall versus raised white letter appearance, and what to inspect before putting a full-size van back on the road.
Tire Size & Fitment
What tire size fits a 1989 Chevrolet Vans G20?
The 1989 Chevrolet Vans G20 uses two primary tire sizes: 225/75R15 and 235/75R15. Both are radial tires built for 15-inch rims, but the correct choice depends on the specific sub-model. Beauville and Sportvan applications use 225/75R15, while the Chevy Van range can use 225/75R15 or 235/75R15, and the Chevy Van with the LH6 option uses 235/75R15.
That means the first step is confirming the exact sub-model and checking the size already mounted on the van. If the van has been changed over to different wheels at some point, verify the actual rim diameter and width before choosing between the two sizes.
What size rim does a 1989 Chevrolet Vans G20 use?
The covered tire fitments for the 1989 Chevrolet Vans G20 use a 15-inch rim diameter. Both primary tire sizes, 225/75R15 and 235/75R15, are designed around that same 15-inch wheel size, so the rim diameter stays consistent even though the tire size can vary by sub-model.
Rim diameter is only part of the check, though. Width matters too, especially when comparing products within either size, and a van that has seen aftermarket wheel changes may not still have its original wheel setup. Reading the existing tire sidewall and measuring the wheel is a worthwhile step before ordering.
Do all 1989 Chevrolet Vans G20 sub-models use the same tire size?
No, the 1989 Chevrolet Vans G20 does not use one tire size across every covered sub-model. Beauville and Sportvan models use 225/75R15, the Chevy Van with the LH6 option uses 235/75R15, and the standard Chevy Van is the overlapping case because it can use either 225/75R15 or 235/75R15.
That variation makes sub-model identification important before comparing brands or sidewall styles. On a standard Chevy Van, checking the current wheel and tire combination becomes especially important, since both primary sizes are used within that model line and appearance choices are available in each.
Choosing the Right Tire
What should I consider when choosing a 1989 Chevrolet Vans G20 tire?
Start with the correct primary size for the van's exact sub-model, then confirm that the tire matches the 15-inch wheel diameter already on the vehicle. From there, compare whether the van needs 225/75R15 or 235/75R15, the available rim-width specifications for the tire being considered, and the load figures shown for individual products.
Appearance is a major part of the decision on a G20 because the available tires include narrow whitewall, wide whitewall, and raised white letter styles. A van kept close to period presentation may call for a different look than one used mainly for road trips, so style and intended use should be weighed together.
What sidewall styles are available for 1989 Chevrolet Vans G20 tires?
1989 Chevrolet Vans G20 tires are available with several sidewall treatments depending on size and product line. The two primary sizes include narrow whitewall and wide whitewall options, and 235/75R15 also includes an RWL, or raised white letter, choice. That gives the G20 owner more than one visual direction without changing the basic radial construction.
A whitewall usually suits a more traditional van presentation, while raised white letters can lean toward a more utility- or truck-flavored look. Since sidewall style does not change the need for correct size and wheel compatibility, it makes sense to settle fitment first and then choose the appearance that best matches the vehicle.
What brands offer tires for the 1989 Chevrolet Vans G20?
The 1989 Chevrolet Vans G20 has tire options from BFGoodrich, Coker Classic, American Classic, Maxxis, Tornel, and Travelstar, depending on which of the two primary sizes the van uses. Those brands appear across several product types, including traditional-looking whitewall radials and a raised white letter all-terrain style in 235/75R15.
Brand choice should be weighed alongside the tire series, sidewall treatment, and wheel-width compatibility rather than treated as a decision by itself. The most useful comparison is between products that share the correct size for the van, since that keeps the choice centered on fitment and the look the owner wants.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Chevrolet Vans G20?
A period-style 1989 Chevrolet Vans G20 starts with the correct primary size for the sub-model, either 225/75R15 or 235/75R15, both in radial construction. From there, the most restoration-oriented choices are usually among the whitewall offerings, since both sizes are available with narrow and wide whitewall treatments across several tire series.
The right look depends on how the van is being presented. A family-trimmed or cruiser-style G20 may suit a different whitewall treatment than a more work-oriented build, and exact originality questions are best checked against marque references or vehicle-specific historical material before settling on one sidewall style.
How does tire construction affect the appearance of a restored 1989 Chevrolet Vans G20?
On the 1989 Chevrolet Vans G20, the primary fitments are radial tires, so construction choice is less about bias-ply versus radial appearance and more about which radial presentation best matches the van. Whitewall width, sidewall lettering, and the overall character of the tire series will do more to shape the finished look than construction alone.
That is useful for restoration-minded owners because it narrows the decision to visual details within the correct fitment. A narrow whitewall gives a different impression than a wide whitewall or raised white letter tire, so the final choice should support the van's intended era feel without moving away from the proper size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Chevrolet Vans G20?
Yes, modifications can change tire fitment on a 1989 Chevrolet Vans G20 even when the tire size appears close to one of the primary options. Aftermarket wheels, changes in wheel width or offset, suspension alterations, and body or fender work can all affect how a 225/75R15 or 235/75R15 tire sits and clears.
That matters most on vans that have changed hands or have been used for custom or utility purposes over the years. A quick inspection of wheel dimensions, sidewall clearance, and steering clearance can prevent choosing a tire that matches the catalog size but conflicts with the van's current setup.
What should I inspect before driving a 1989 Chevrolet Vans G20 on new tires?
Before driving a 1989 Chevrolet Vans G20 on new tires, inspect the wheels for damage, confirm the rim diameter and width, and check that the chosen tire size matches the van's sub-model and actual wheel setup. It is also smart to look at suspension condition, steering components, and basic tire inflation once the tires are mounted.
Older full-size vans can spend long periods parked, so the first road test should be approached carefully. Watching for rubbing, unusual vibration, air loss, or uneven stance early on helps catch fitment or mechanical issues before the van is put into regular use or taken on a longer drive.
How should 225/75R15 or 235/75R15 tires on a collector 1989 Chevrolet Vans G20 be maintained?
Tires on a collector 1989 Chevrolet Vans G20 should be checked regularly for air pressure, tread wear, sidewall cracking, cuts, bulges, and signs of long-term aging. That applies whether the van runs 225/75R15 or 235/75R15, since low annual mileage does not prevent age-related deterioration in a tire.
Storage conditions matter almost as much as mileage on a collector van. Keeping the vehicle away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, and a walk-around inspection before each drive is a good habit for any G20 that is not used every day.
