The 1987 Chevrolet Trucks Blazer sits in the square-body era, when full-size sport utility vehicles were expected to handle daily road use, rough weather, and light off-road duty with equal confidence. Buyers today often approach this Blazer with the same split priorities: preserving its period presence while choosing tires that suit how it will actually be driven. This model uses radial tire fitments in 215/75R15, 235/75R15, and 31X10.50R15, all built around a 15-inch rim. That opens the door to everything from traditional whitewall-style radials to all-terrain raised white letter options. The key is matching the exact wheel and intended look before settling on a size.
Which Tire Size Is Right for The 1987 Chevrolet Trucks Blazer
Three primary tire sizes apply to the 1987 Chevrolet Trucks Blazer, and they share the same 15-inch rim diameter but differ in section width, overall height, and overall character. Since both Custom Deluxe and Silverado can use all three sizes, the first step is confirming which wheel and tire setup is already on the truck, especially if it has been changed over the years.
215/75R15 is a metric radial size where 215 identifies the nominal section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and 15 is the rim diameter in inches. On a 1987 Chevrolet Trucks Blazer, this size represents the narrower end of the primary fitment range while keeping the correct 15-inch wheel relationship. Available choices include BFGoodrich, Coker Classic, American Classic, Maxxis, Tornel, and Travelstar, with narrow whitewall, wide whitewall, and RBL sidewall treatments across several tire series. It is a useful size to evaluate when the goal is a more stock-appearing road setup on a standard 15-inch wheel.
235/75R15 follows the same metric radial format, with a 235-millimeter nominal section width, a 75-series aspect ratio, radial construction, and a 15-inch rim diameter. For the 1987 Chevrolet Trucks Blazer, it gives a broader footprint than 215/75R15 while staying within the same basic wheel diameter family. Product choices include BFGoodrich, American Classic, Coker Classic, Maxxis, Tornel, and Travelstar, with raised white letter, narrow whitewall, and wide whitewall presentations in series such as All Terrain T/A KO2, Star Series, Silvertown Radial, and Coker Classic Radial. This size deserves close attention when balancing everyday drivability, visual stance, and wheel-width compatibility.
31X10.50R15 is a flotation-style radial size that expresses the tire by approximate overall diameter, section width, and rim diameter rather than by modern metric aspect-ratio format. On the 1987 Chevrolet Trucks Blazer, it stands apart from the two metric sizes by delivering a taller, wider light-truck style fitment on the same 15-inch wheel diameter. The available option in this size is the BFGoodrich All-Terrain T/A KO2 with raised white letter styling, reinforcing its truck-oriented character. This size should be checked carefully against the actual wheel width and overall clearance if the Blazer's suspension, wheels, or stance have been altered.
Tire fitment is straightforward here because both covered sub-models share the same three radial tire sizes. Checking the exact sub-model still helps confirm the truck's presentation and current wheel setup, especially on vehicles that may have changed hands or been modified over time.

1987 Chevrolet Trucks Blazer Custom Deluxe
The 1987 Chevrolet Trucks Blazer Custom Deluxe uses the same radial fitment range found across this model line, all centered on a 15-inch rim. Tire selection usually comes down to confirming which of the three existing size paths is on the truck now, then choosing between whitewall-style road tires and a more truck-oriented all-terrain presentation.
The 1987 Chevrolet Trucks Blazer Silverado shares the same three radial tire sizes as the Custom Deluxe, so fitment does not change by sub-model alone. The practical decision is whether to stay with a narrower metric size, move to the broader 235/75R15 setup, or confirm that a 31X10.50R15 combination matches the truck's wheel width and clearance.
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.

Tire Size & Fitment
What tire size fits a 1987 Chevrolet Trucks Blazer?
The 1987 Chevrolet Trucks Blazer uses three primary radial tire sizes: 215/75R15, 235/75R15, and 31X10.50R15. All three are 15-inch fitments, but they differ in width, height, and overall tire character, so the correct choice depends on the wheel and setup already on the truck.
A Blazer that still wears its long-established wheel package may point clearly to one of those sizes, but older trucks are often changed over time. Matching the existing wheel width, checking body and steering clearance, and confirming whether the truck is set up for road-style whitewalls or a taller all-terrain tire will help narrow the right choice.
What size rim does a 1987 Chevrolet Trucks Blazer use?
The primary tire sizes for a 1987 Chevrolet Trucks Blazer are built around a 15-inch rim diameter. That is consistent across 215/75R15, 235/75R15, and 31X10.50R15, even though the tires themselves vary significantly in section width and overall diameter.
Rim diameter is only the first checkpoint, because a 15-inch wheel can still differ in width from one truck to another. Looking at the actual wheel before ordering tires matters most when stepping up from a narrower 215/75R15 to a wider 235/75R15 or a 31X10.50R15 all-terrain tire that calls for a broader wheel range.
Do all 1987 Chevrolet Trucks Blazer sub-models use the same tire size?
The Custom Deluxe and Silverado versions of the 1987 Chevrolet Trucks Blazer share the same three primary tire sizes: 215/75R15, 235/75R15, and 31X10.50R15. Fitment does not split by sub-model name here, so the sub-model alone does not determine which one is on the truck.
That makes the next step more practical than trim-based: verify the actual wheel and tire package on the vehicle. Since all three sizes are possible, the better question is whether the Blazer is running a narrower metric radial, a wider metric radial, or a taller flotation-style all-terrain setup on its 15-inch wheels.
Choosing the Right Tire
What should I consider when choosing a 1987 Chevrolet Trucks Blazer tire?
Start with the tire size already matched to the truck's wheels, because the 1987 Chevrolet Trucks Blazer uses three different 15-inch radial sizes. From there, look at the intended role of the vehicle, since a road-oriented whitewall radial and a taller all-terrain RWL tire create very different visual and practical results.
Rim-width compatibility, load capacity, sidewall style, and tire series all matter once the correct size is established. A truck kept close to period road use may lean toward one of the whitewall options in 215/75R15 or 235/75R15, while a more utility-focused Blazer may call for the 31X10.50R15 all-terrain setup if the wheel and clearance allow it.
What sidewall styles are available for 1987 Chevrolet Trucks Blazer tires?
Sidewall choices for the 1987 Chevrolet Trucks Blazer include narrow whitewall, wide whitewall, RBL, and RWL depending on the tire size and product series. The two metric sizes offer the broadest appearance range, while 31X10.50R15 is represented by a truck-style raised white letter all-terrain option.
That variety lets the tire change the truck's presentation without changing the vehicle itself. Whitewall radials tend to suit a more restoration-oriented or boulevard look, while RBL and RWL sidewalls support a more utility or off-road character. The best choice depends on whether the Blazer is being finished as a period-style cruiser, a driver, or a more rugged square-body truck.
What brands offer tires for the 1987 Chevrolet Trucks Blazer?
Tires for the 1987 Chevrolet Trucks Blazer are available from BFGoodrich, Coker Classic, American Classic, Maxxis, Tornel, and Travelstar. Brand availability depends on size, with the broadest mix appearing in 215/75R15 and 235/75R15, while 31X10.50R15 is represented by a BFGoodrich all-terrain offering.
Choosing among them is less about ranking brands and more about matching the truck's needs. Some options emphasize traditional whitewall styling in series such as Star Series, Silvertown Radial, and Coker Classic Radial, while BFGoodrich covers all-terrain use and a truck-focused sidewall presentation. Once the size is confirmed, comparing sidewall style, rim-width range, and load figures becomes more useful than comparing brand names alone.
Restoration & Appearance
Which tire should I choose for a period-style 1987 Chevrolet Trucks Blazer?
A period-style 1987 Chevrolet Trucks Blazer usually starts with choosing the right primary size first, then selecting a radial that matches the truck's visual direction. In 215/75R15 and 235/75R15, there are several whitewall-style options that create a more traditional road-going appearance than a truck-oriented raised white letter all-terrain tire.
The final choice depends on how original-looking or era-appropriate the Blazer needs to appear. A narrower or wider metric radial with a narrow or wide whitewall can support a restoration-minded presentation, while 31X10.50R15 leans more toward a rugged stance. When exact originality matters, compare the truck against marque references, photos, and build-specific documentation before settling on a sidewall treatment.
How does tire construction affect the appearance of a restored 1987 Chevrolet Trucks Blazer?
Construction is simpler on a 1987 Chevrolet Trucks Blazer because the primary fitments are radial rather than bias-ply. That means the visual difference comes less from construction changes and more from tire size, tread character, and sidewall treatment such as narrow whitewall, wide whitewall, RBL, or RWL.
A restored Blazer can look notably different depending on whether it wears a road-style metric radial or a taller all-terrain tire. The 215/75R15 and 235/75R15 sizes give the broadest appearance range for an era-conscious finish, while 31X10.50R15 adds a more aggressive truck stance. Matching the tire's visual style to the wheel, ride height, and intended use is what keeps the restoration cohesive.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1987 Chevrolet Trucks Blazer?
Yes, modifications can affect tire fitment on a 1987 Chevrolet Trucks Blazer even when the tire still uses the correct 15-inch rim diameter. Changes such as aftermarket wheels, different wheel widths, suspension lifts, lowering, worn springs, or body alterations can all influence whether 215/75R15, 235/75R15, or 31X10.50R15 is still the right working size.
That matters most with the taller and wider choices, since a size that belongs in the Blazer's fitment range may still need extra clearance on an altered truck. Checking steering sweep, fender room, ride-height consistency, and wheel width before installation helps prevent rubbing or mismatch. Older trucks should also be inspected for prior owner changes that are easy to miss at a glance.
What should I inspect before driving a 1987 Chevrolet Trucks Blazer on new tires?
Before driving a 1987 Chevrolet Trucks Blazer on new tires, inspect the wheels for the correct 15-inch diameter and suitable width for the chosen tire. It is also wise to check for suspension wear, steering looseness, uneven ride height, and any signs that the existing tire package may have been compensating for clearance or alignment issues.
A short road test should follow a close visual check for clearance at full steering lock and during suspension movement. Tire pressure should be set appropriately for the tire in use, and the truck should be watched for pull, vibration, or contact with inner fenders. On a collector-era SUV, even fresh-looking components can be aged, so condition matters as much as appearance.
How should tires on a collector 1987 Chevrolet Trucks Blazer be maintained?
Tires on a collector 1987 Chevrolet Trucks Blazer should be checked regularly for pressure loss, sidewall cracking, bulges, tread damage, and signs of age-related hardening. Because many surviving Blazers are driven seasonally or stored for long periods, tire condition can decline from time and environment even when tread wear looks minimal.
Consistent maintenance includes keeping the truck on properly inflated tires, moving it often enough to avoid long-term flat spotting, and storing it away from prolonged sunlight, moisture, and ozone-producing equipment. Occasional inspections of alignment and suspension condition also help protect the tires, especially on trucks running wider 235/75R15 or taller 31X10.50R15 combinations.
