The 1986 Chevrolet Trucks S10 Blazer came from the compact SUV era when smaller four-wheel-drive and sport-utility models were becoming everyday vehicles instead of strictly work rigs. Its shorter footprint and truck-based roots gave it a different character than full-size Blazers, which makes tire fitment especially important to stance, clearance, and overall appearance. This model uses 15-inch radial tire fitments, with 195/75R15, 205/75R15, and 235/75R15 sizes depending on sub-model. Available choices range from traditional whitewall treatments to redline, goldline, and raised white letter styles. The right decision starts with the exact trim and wheel setup, then narrows to the look and road use that suit the truck.
Which Tire Size Is Right for The 1986 Chevrolet Trucks S10 Blazer
Three tire sizes apply to the 1986 Chevrolet Trucks S10 Blazer, and the correct one depends first on the exact sub-model. All of them are radial tires built for a 15-inch rim, but the fitment splits between 195/75R15 and 205/75R15 on most trims and 235/75R15 on the w/Z71 Pkg. version. Before comparing brands or sidewall styles, confirm which trim the truck is and whether it still has the intended wheel setup.
195/75R15 is a metric radial size in which 195 refers to the section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 15 is the wheel diameter in inches. On the 1986 Chevrolet Trucks S10 Blazer, this size is one of the standard 15-inch radial fitments used on several sub-models. Available choices focus on a traditional whitewall presentation, including narrow and wide whitewall styles from Coker Classic and American Classic. It is a useful fitment to evaluate when maintaining a stock-type look and confirming that the truck still carries the wheel and trim combination intended for this size.
205/75R15 is a metric radial size with a 205-millimeter nominal section width, a 75-series profile, radial construction, and a 15-inch rim diameter. This is another primary fitment for several 1986 Chevrolet Trucks S10 Blazer sub-models and offers the broadest variety of product choices. Buyers can sort through BFGoodrich, American Classic, Coker Classic, Maxxis, Tornel, and Travelstar options, with sidewall treatments that include narrow whitewall, wide whitewall, goldline, and redline. It is often the size that gives the most flexibility when the goal is to balance trim-correct appearance, brand preference, and wheel compatibility on a 15-inch setup.
235/75R15 is a metric radial size where 235 is the nominal section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and 15 is the rim diameter. On the 1986 Chevrolet Trucks S10 Blazer, this size belongs to the w/Z71 Pkg. sub-model rather than the rest of the range. Product choices stretch from classic whitewall radials to a BFGoodrich All-Terrain T/A KO2 with raised white letters, which gives this fitment a noticeably broader appearance range. It deserves a closer look when the truck has the Z71 package or when wheel width and clearance need to be confirmed around the larger tire footprint.
Sub-model fitment matters on the 1986 Chevrolet Trucks S10 Blazer because most trims share the smaller metric radial sizes, while the w/Z71 Pkg. uses a larger 235/75R15 fitment. Identifying the exact trim is the quickest way to narrow the correct tire size before comparing brands, sidewall styles, or wheel compatibility.

1986 Chevrolet Trucks S10 Blazer Base
The 1986 Chevrolet Trucks S10 Blazer Base uses the smaller 15-inch radial fitments shared across most of the model line. Tire selection here usually comes down to confirming whether the truck takes 195/75R15 or 205/75R15, then choosing the preferred sidewall treatment and product character within that size.
The 1986 Chevrolet Trucks S10 Blazer Durango follows the same general fitment pattern as the other non-Z71 trims, using 15-inch radial tires in the smaller size group. Once the exact wheel setup is confirmed, the decision shifts toward appearance, with whitewall and other period-style radial choices available depending on the final size.
The 1986 Chevrolet Trucks S10 Blazer Sport uses one of the two smaller 15-inch radial sizes rather than the larger Z71-package tire. That makes wheel confirmation important first, after which the buyer can sort through brand, sidewall, and overall presentation choices without stepping outside the intended fitment range.
The 1986 Chevrolet Trucks S10 Blazer Tahoe shares the same smaller radial fitment family used by the other mainstream trims. The practical choice is to verify whether the truck is set up for 195/75R15 or 205/75R15, then decide whether a narrow or wide whitewall look suits the vehicle best.
The 1986 Chevrolet Trucks S10 Blazer w/Z71 Pkg. uses 235/75R15, separating it from the rest of the sub-model range. That larger radial size opens the door to both traditional whitewall choices and an all-terrain raised white letter option, but wheel width and overall clearance still deserve a careful check before replacement.
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.

Owners of a 1986 Chevrolet Trucks S10 Blazer usually need to sort out the correct tire size by trim first, then compare radial styles, wheel fitment, appearance, and road-use considerations. These FAQs focus on that decision process.
Tire Size & Fitment
What tire size fits a 1986 Chevrolet Trucks S10 Blazer?
The 1986 Chevrolet Trucks S10 Blazer uses three primary tire sizes: 195/75R15, 205/75R15, and 235/75R15. The Base, Durango, Sport, and Tahoe trims use the smaller 195/75R15 or 205/75R15 radial sizes, while the w/Z71 Pkg. uses 235/75R15 on a 15-inch rim.
The key is matching the tire to the exact sub-model and wheel setup rather than assuming every S10 Blazer uses the same size. A truck that has had wheel changes over the years should be checked carefully for actual rim width, tire clearance, and overall stance before choosing among the available radial options.
What size rim does a 1986 Chevrolet Trucks S10 Blazer use?
The tire fitments for the 1986 Chevrolet Trucks S10 Blazer all use a 15-inch rim diameter. That applies across the 195/75R15, 205/75R15, and 235/75R15 sizes, so the wheel diameter stays consistent even though the tire width and overall proportions vary by sub-model.
Rim diameter is only the first check, though. Wheel width still matters, especially when moving between the smaller trim sizes and the wider 235/75R15 used on the w/Z71 Pkg. If the truck has aftermarket wheels, verify the actual wheel dimensions and available clearance before settling on a replacement tire.
Why does the 1986 Chevrolet Trucks S10 Blazer have more than one tire size?
The 1986 Chevrolet Trucks S10 Blazer has more than one tire size because fitment varies by sub-model. Most trims fall into the 195/75R15 and 205/75R15 group, while the w/Z71 Pkg. uses a larger 235/75R15 radial tire, giving that configuration a different tire profile and footprint.
That means the first step is identifying the exact trim rather than comparing all available products at once. Once the correct sub-model is confirmed, the decision becomes much easier: stay within the correct 15-inch size family, then compare sidewall styling, brand, and product type without crossing into a fitment meant for another version.
Choosing the Right Tire
What should I consider when choosing a 205/75R15 tire for a 1986 Chevrolet Trucks S10 Blazer?
A 205/75R15 tire for a 1986 Chevrolet Trucks S10 Blazer should be chosen by confirming that this is the actual fitment for the truck, then comparing radial construction details, sidewall style, and wheel compatibility. This size has the widest selection, including narrow whitewall, wide whitewall, goldline, and redline options.
That variety makes appearance an important part of the decision, especially on a preserved or restored truck. It also helps to compare rim-width guidance among the available products, since some are suited to a narrower wheel range than others. Once the wheel setup is verified, the remaining choice is largely about presentation and intended use.
What sidewall styles are available for 1986 Chevrolet Trucks S10 Blazer tires?
Sidewall choices for the 1986 Chevrolet Trucks S10 Blazer include narrow whitewall, wide whitewall, goldline, redline, and raised white letter styles, depending on the tire size. The smaller 195/75R15 fitment centers on whitewall options, while 205/75R15 adds goldline and redline choices, and 235/75R15 includes whitewall and RWL offerings.
That means the sidewall can change the truck's character noticeably even when the size stays correct. A whitewall can lean more traditional, while a redline, goldline, or raised white letter treatment creates a different period look. Matching the sidewall to the trim, stance, and intended presentation usually narrows the product field quickly.
What brands offer tires for the 1986 Chevrolet Trucks S10 Blazer?
Tires for the 1986 Chevrolet Trucks S10 Blazer are available from Coker Classic, American Classic, BFGoodrich, Maxxis, Tornel, and Travelstar. Brand availability changes with the tire size, so the broadest brand selection appears once the correct fitment has been confirmed for the exact sub-model.
Brand choice should be weighed alongside size, sidewall style, and product series rather than by name alone. Some offerings emphasize a traditional whitewall presentation, while others bring in details such as goldline, redline, or raised white letters. Comparing those visual and fitment differences usually matters more than treating one brand as universally better.
Restoration & Appearance
Which tire should I choose for a period-style 1986 Chevrolet Trucks S10 Blazer?
A period-style 1986 Chevrolet Trucks S10 Blazer starts with the correct size for the trim, then moves to the sidewall and series that match the truck's intended presentation. The non-Z71 trims center on 195/75R15 or 205/75R15 radials, while the w/Z71 Pkg. uses 235/75R15 and offers a broader mix of classic and truck-oriented looks.
Whitewall radials are the most obvious restoration-oriented path in these sizes, but the exact width and style can change the truck's appearance quite a bit. Buyers pursuing strict originality should compare the tire choice against vehicle-specific photos, trim literature, or marque references, since a period-style tire is not automatically the exact factory presentation.
How does tire construction affect the appearance of a restored 1986 Chevrolet Trucks S10 Blazer?
Tire construction is straightforward on the 1986 Chevrolet Trucks S10 Blazer because the primary fitments are radial across all listed sizes. That keeps the visual decision centered less on bias-ply versus radial shape and more on the sidewall treatment, tire series, and the difference between the smaller trim sizes and the wider Z71-package fitment.
Appearance still changes noticeably within that radial family. A narrow whitewall gives a cleaner, lighter presentation, a wide whitewall creates a more formal look, and raised white letters push the truck toward a more rugged period feel. Choosing within the correct size keeps the restored truck visually balanced without forcing a mismatch in proportions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 Chevrolet Trucks S10 Blazer?
Modifications can absolutely affect tire fitment on a 1986 Chevrolet Trucks S10 Blazer, even when the tire size itself is one of the correct original-style fitments. Wheel-width changes, offset differences, suspension lifts or lowering, and body or fender alterations can all change how a 195/75R15, 205/75R15, or 235/75R15 tire sits on the truck.
That matters most when moving toward the larger 235/75R15 fitment or when replacing tires on a truck with unknown wheel history. Check steering travel, inner clearance, and fender room before mounting new tires. A vehicle that looks stock at a glance may still have enough wheel or suspension variation to make careful measurement worthwhile.
What should I inspect before driving a 1986 Chevrolet Trucks S10 Blazer on new tires?
Before driving a 1986 Chevrolet Trucks S10 Blazer on new tires, inspect the wheels for correct diameter and condition, confirm that the tires are properly seated, and check inflation pressure carefully. It also helps to look over suspension and steering components so the new tires are not immediately affected by looseness, misalignment, or worn parts.
A short initial road test is a smart follow-up. Listen for rubbing, watch for any pull or vibration, and recheck pressure after the first drive. On an older truck, this step is especially useful because a fresh set of tires can reveal wheel, brake, or front-end issues that were less obvious with the old tires in place.
How often should tires on a 1986 Chevrolet Trucks S10 Blazer be inspected?
Tires on a 1986 Chevrolet Trucks S10 Blazer should be inspected regularly, especially if the truck is driven only occasionally or spends long periods stored. Collector and hobby vehicles can show age-related issues even with low mileage, so tread alone is not enough; the sidewalls, air pressure, and general condition deserve routine attention.
A visual check before each drive and a more thorough inspection at regular intervals is a sensible approach. Look for cracking, cuts, bulges, uneven wear, and any sign of slow air loss. Storage conditions matter too, since prolonged sunlight, heat, moisture, and ozone exposure can shorten tire life on vehicles that are not used every day.
