1987 Mercury Cougar Tires

The 1987 Mercury Cougar uses three radial tire sizes: 205/70R14, 215/70R14, and 225/60R15. The LS is associated with the two 14-inch sizes, while the XR-7 uses 225/60R15 on a 15-inch wheel.

The practical decision starts with the exact sub-model and the wheels currently on the car. An LS with 14-inch wheels should stay within the 14-inch fitment group, while an XR-7 should be matched to the 15-inch setup. If the car has changed hands or has aftermarket wheels, confirm the actual wheel diameter before choosing a tire.

A 1987 Mercury Cougar uses either a 14-inch or 15-inch rim, depending on the sub-model and tire size. The 205/70R14 and 215/70R14 fitments use 14-inch rims, and the 225/60R15 fitment uses a 15-inch rim.

That distinction matters because a 14-inch tire and a 15-inch tire are not interchangeable, even if their overall dimensions appear close. Check the wheel itself rather than relying on memory, especially on a car that may have had replacement wheels at some point. Confirming wheel diameter first prevents choosing a tire from the wrong fitment family.

The 1987 Mercury Cougar has more than one tire size because tire fitment changes by sub-model. LS models are tied to 14-inch radial sizes, while the XR-7 uses a 15-inch radial size with a different profile.

That means the correct tire is not chosen by model name alone. A buyer should identify whether the car is an LS or XR-7, then confirm the wheel diameter currently installed. This is especially helpful on cars that have seen wheel swaps, suspension updates, or cosmetic changes that make the original trim-level fitment less obvious at a glance.

Start with the correct size for the exact car: 205/70R14 or 215/70R14 for LS applications, and 225/60R15 for the XR-7. From there, compare radial construction details such as brand, tire series, sidewall style, rim-width compatibility, and load figures where those specifications matter to the way the car will be used.

Appearance is often a major part of the decision on a Cougar from this era. Blackwall, whitewall, redline, dual-redline, pin-white-stripe, and RWL choices can change the car's visual character as much as the wheel does. Match the tire to the car's actual wheel setup, intended road use, and the presentation you want rather than choosing on size alone.

Sidewall choices for the 1987 Mercury Cougar include blackwall, narrow whitewall, wide whitewall, redline, dual-redline, pin-white-stripe, and RWL. Availability varies by tire size, so the exact range of sidewall treatments depends on whether the car uses a 14-inch LS fitment or the 15-inch XR-7 fitment.

That sidewall choice can shift the car's personality from subdued and luxury-leaning to more performance-oriented or restoration-inspired. Whitewall and pin-stripe styles often suit a more traditional presentation, while blackwall and RWL typically create a sportier look. Once the correct size is confirmed, sidewall treatment becomes one of the most important visual decisions on the page.

Brands available for 1987 Mercury Cougar fitments include BFGoodrich, Michelin, Maxxis, Cooper, Goodyear, and Avon. Brand availability depends on the exact tire size, so some names appear only in certain 14-inch or 15-inch fitments rather than across the entire Cougar range.

The best way to use that variety is to compare the tire within the correct size rather than trying to chase a brand first. Some offerings lean toward traditional sidewall treatments, while others emphasize blackwall or raised white letter styling. Brand becomes more meaningful after the sub-model, wheel diameter, and desired appearance are already settled.

A period-style 1987 Mercury Cougar tire starts with the correct sub-model fitment and wheel diameter, then narrows down by sidewall treatment and series. LS models can be paired with 14-inch whitewall, pin-white-stripe, redline, or blackwall radials, while the XR-7's 225/60R15 fitment also opens the door to blackwall, RWL, redline, and wide whitewall options.

The right choice depends on whether the car is being presented as a luxury-leaning coupe, a sportier XR-7, or a personalized driver with strong period cues. Exact originality claims should be checked against vehicle-specific references, but the correct size and era-appropriate sidewall style provide a strong starting point for a restoration-minded selection.

Tire construction is straightforward on the 1987 Mercury Cougar because the primary fitments are radial. That means the visual difference comes less from bias-ply versus radial construction and more from profile, sidewall styling, and the overall character of the chosen tire series.

A blackwall or RWL tire can push the car toward a sport-oriented 1980s look, while narrow or wide whitewalls can make the same Cougar read as more formal and luxury-focused. Since the fitments are already radial, the restoration decision is mostly about preserving the right wheel diameter and selecting a sidewall treatment that suits the car's intended presentation.

Yes. Modifications can affect tire fitment on a 1987 Mercury Cougar even when the tire size itself is correct for an LS or XR-7. Aftermarket wheels, changes in wheel width, suspension lowering, replacement springs, or body alterations can all influence clearance at the fender, suspension, and steering points.

A car that has been altered should be checked as it sits, not as it left the factory. Verify wheel diameter first, then inspect wheel width and available clearance before committing to a tire. This matters most when moving between visual styles or replacing old tires on a Cougar that may have accumulated changes over several decades of ownership.

Before driving a 1987 Mercury Cougar on new tires, inspect the wheels for damage, confirm the wheel diameter matches the intended tire size, and look over suspension and steering components for looseness or wear. Check that the tires are properly seated, inflated, and free from shipping or installation damage before putting the car into regular road use.

It also helps to confirm there is no rubbing at full steering lock and no contact through normal suspension movement. A collector-era car may have old bushings, sagging springs, or alignment issues that only become obvious once fresh tires are installed. A careful once-over makes the first drive more useful and reduces the chance of avoidable fitment surprises.

Tires on a 1987 Mercury Cougar should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Collector-era cars benefit from routine checks for air loss, tread wear, sidewall cracking, bulges, cuts, and signs of uneven wear that may point to alignment or suspension issues.

A quick visual check before each drive is a good habit, and a more thorough inspection should be part of seasonal maintenance or any longer trip preparation. Storage conditions also matter, since prolonged exposure to heat, sunlight, moisture, and ozone sources can accelerate deterioration. Low annual mileage does not eliminate the need to monitor tire condition closely.
