In 1986, BMW balanced compact sport sedans, executive four-doors, and grand touring coupes with the kind of engineering focus that made the brand a benchmark for enthusiasts. The 3 Series, 5 Series, 6 Series, and 7 Series all carried distinct personalities, and tire choice followed those differences more closely than many buyers expect. Across nine 1986 BMW models, five radial sizes appear, with fitment varying by model and in several cases by wheel system, including both conventional 14-inch sizes and metric TRX fitments. Before choosing a tire for 1986 BMW, the first step is confirming the exact model and whether it uses standard 14-inch wheels or BMW's metric TRX setup.
Which Tire Size Is Right for Your 1986 BMW
Five tire sizes are used across 1986 BMW vehicles, and they vary by model rather than carrying across the entire range. The real decision starts with wheel type: some models use conventional 14-inch radial sizes, while others use metric TRX sizes that require the correct 390mm rim. Sorting that out first saves time and points you toward the right tire family for your car.
Year(s): 1986|Fit(s): 325, 325e, 325es|Construction: Radial|Rim: 14 in
195/65R14 is a metric radial size with a 195-millimeter section width, a 65-series aspect ratio, and a 14-inch rim diameter. This size is available in Michelin with a blackwall sidewall, and the tire carries a V speed rating to 149 mph with tubeless construction. It is specific to the 325, 325e, and 325es rather than universal across 1986 BMW models. Owners seeking the factory-style 3 Series sizing used on these cars should stay with this format and confirm their wheels remain the original 14-inch type.
Year(s): 1986|Fit(s): 524td, 528e|Construction: Radial|Rim: 14 in
195/70R14 is a metric radial size with a 195-millimeter section width, a 70-series aspect ratio, and a 14-inch rim diameter. This size is available from Dunlop in blackwall form, and the tire carries a V speed rating to 149 mph. It applies to the 524td and 528e only, where it represents the conventional 14-inch-wheel fitment rather than the metric TRX alternative also seen on those models. It suits owners keeping those cars on standard-inch wheels and a traditional late-classic BMW tire profile.
200/60R390 is a metric radial size with a 200-millimeter section width, a 60-series aspect ratio, and a 390mm metric rim diameter rather than a conventional inch-based wheel. Michelin offers this size in blackwall form, tubeless, with a V speed rating to 149 mph. This size is specific to the 524td, 528e, and 535i models that use the TRX wheel system, so it is not interchangeable with 14-inch tires. It is the correct path for owners preserving or retaining original metric TRX wheels.
Year(s): 1986|Fit(s): 635CSi, 735i, L7|Construction: Radial|Rim: 14 in
205/70R14 is a metric radial size with a 205-millimeter section width, a 70-series aspect ratio, and a 14-inch rim diameter. It is available from Maxxis and BFGoodrich in blackwall-adjacent specialty styles including narrow whitewall, RWL, redline, and dual redline; speed rating and load details vary by product, with the BFGoodrich Radial T/A carrying an S rating to 112 mph and other versions presented without a speed letter in the sidewall marking shown here. This size is used only on the 635CSi, 735i, and L7 among 1986 BMW models. It gives buyers the broadest sidewall-style choice of any size in the range, which matters more here than construction because every option is radial.
220/55R390 is a metric radial size with a 220-millimeter section width, a 55-series aspect ratio, and a 390mm metric rim diameter. Michelin offers this TRX size as a blackwall tubeless radial with a W speed rating to 168 mph. It is specific to the 635CSi, 735i, and L7 fitted with metric TRX wheels and does not mount on 14-inch rims. Owners maintaining the original TRX setup should remain with this metric size and verify the wheel marking before selecting a tire.
Nine BMW models are covered for 1986, spanning the E30 3 Series, E28 5 Series, E24 6 Series, and E23 7 Series families. Tire size does vary by model, and in several cases it also depends on whether the car carries standard 14-inch wheels or metric TRX rims, so identifying the exact model is essential before choosing a tire. Select your model below to narrow the fitment history and see the tire options that match it.
1986 BMW 325
The 1986 BMW 325 sat in the heart of the E30 range, combining compact dimensions with the balanced road manners that helped define BMW's reputation in the 1980s. Its tires mount on 14-inch wheels in this fitment, making it one of the straightforward conventional-wheel applications in the 1986 BMW lineup.
The 325e was the efficiency-focused E30, tuned more for relaxed torque and everyday drivability than the rev-happy character associated with other 3 Series variants. It uses a 14-inch tire fitment here, which keeps it in the standard inch-based wheel category rather than the TRX family.
The 325es blended the eta drivetrain theme with a sportier presentation, giving buyers an E30 that leaned upscale without leaving the 3 Series footprint. Its tire fitment mounts on 14-inch wheels, so the key concern is staying with the correct E30 size rather than sorting between inch and metric TRX systems.
BMW's 524td brought European diesel character to the American luxury-sport sedan conversation, standing apart within the E28 line for its long-distance personality and rarity today. This model appears with both conventional 14-inch fitment and a 390mm TRX metric fitment, so wheel identification matters before anything else.

The 535i represented the more performance-oriented side of the E28 range, with a stronger enthusiast following and a more sporting mission than the eta models. In this fitment group it mounts on 390mm TRX wheels, making metric-rim confirmation the central step before choosing tires.
BMW's 635CSi was the flagship grand touring coupe of the era, known for its long-hood proportions, refined chassis, and unmistakable shark-nose styling. It appears with both a conventional 14-inch tire size and a 390mm TRX option, so the wheel itself determines which path applies.

205/70R14 — radial, standard 14-inch wheel fitment
The 735i delivered BMW's executive-sedan formula in full-size form, blending understated luxury with the brand's driver-oriented engineering character. This model uses either a 14-inch conventional fitment or a 390mm TRX fitment depending on wheel equipment, which is the first thing to verify on the car.

The L7 was the more luxurious interpretation of BMW's 7 Series, aimed at buyers who wanted the E23's engineering with a higher level of comfort and presentation. Like the 735i and 635CSi, it appears with either 14-inch inch-based tires or the 390mm TRX system, so wheel type drives the tire decision.

Nine products are available across five tire sizes for 1986 BMW vehicles. 195/65R14 comes as a Michelin radial blackwall, 195/70R14 as a Dunlop radial blackwall, 200/60R390 and 220/55R390 as Michelin TRX radial blackwalls, and 205/70R14 in five radial choices from Maxxis and BFGoodrich with blackwall, narrow whitewall, RWL, redline, and dual redline styles. Confirm wheel type first, since speed ratings can vary between products.
These FAQs sort out the big 1986 BMW questions: which models use 14-inch tires versus metric TRX sizes, how sidewall style choices differ by size, and what to inspect on a collector BMW that may spend long periods between drives.
Size Basics & Fitment
What tire sizes fit 1986 BMW vehicles?
1986 BMW vehicles use five different tire sizes across nine models: 195/65R14 for the 325, 325e, and 325es; 195/70R14 for the 524td and 528e; 200/60R390 for the 524td, 528e, and 535i; 205/70R14 for the 635CSi, 735i, and L7; and 220/55R390 for the 635CSi, 735i, and L7. The inch-based sizes mount on 14-inch wheels, while the TRX sizes mount on 390mm metric rims.
That means year and make alone are not enough to pick a tire for a 1986 BMW. You need the exact model, and on several models you also need to confirm whether the car still has standard 14-inch wheels or the original TRX metric wheels. On 205/70R14 applications, rim width guidance spans 5.00 to 7.50 inches depending on the tire chosen. On TRX sizes, the wheel must match the metric tire exactly.
What does 200/60R390 mean on a 1986 BMW tire?
On a 1986 BMW, 200/60R390 is a metric radial size. The 200 is the section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 390 is the wheel diameter in millimeters rather than inches. That last part is the key distinction, because this size belongs to BMW's TRX system and fits only a 390mm metric rim.
Buyers often confuse TRX tires with conventional 15-inch or 14-inch sizes because the numbers look broadly similar at a glance, but they are not interchangeable. If your 1986 BMW 524td, 528e, or 535i still wears TRX wheels, you need to stay with 200/60R390. If the car has been converted to standard inch-based wheels, the tire choice changes with the wheel, not just the body style.
Do all 1986 BMW models use the same tire size?
No, 1986 BMW models do not share one universal tire size. The E30 325-family cars use 195/65R14, the 524td and 528e can use either 195/70R14 or 200/60R390 depending on wheel system, the 535i uses 200/60R390, and the 635CSi, 735i, and L7 use either 205/70R14 or 220/55R390 depending on wheel type. Every size in this range is radial, but the wheel diameter standard changes.
That model-by-model spread matters because two 1986 BMW sedans parked side by side may need completely different tires even if they seem similar in era and appearance. The practical shortcut is to identify the model first, then verify whether the wheels are conventional 14-inch rims or metric TRX rims. Once that is settled, the correct size family becomes much easier to narrow down.
Buying the Right Tire
What sidewall styles are available for 1986 BMW tires?
Sidewall style depends heavily on size in the 1986 BMW range. The 195/65R14, 195/70R14, 200/60R390, and 220/55R390 options are blackwall radials. The 205/70R14 size adds the most visual variety, with blackwall-oriented performance styling, narrow whitewall, raised white letters, redline, and dual redline options available from Maxxis and BFGoodrich.
For most 1986 BMW restorations, blackwall remains the most era-appropriate visual direction, especially on TRX-equipped cars and standard late-1980s German sedan applications. The 205/70R14 specialty sidewalls give more freedom for a personalized look, but they can change the visual character of the car more than many owners expect. If authenticity matters, compare your target finish to period BMW photos and event judging standards before choosing a decorative sidewall.
What brands make tires for 1986 BMW vehicles?
Michelin, Dunlop, Maxxis, and BFGoodrich all cover portions of the 1986 BMW range. Michelin supplies 195/65R14 through the MXV3-A and both TRX sizes through the TRX-B line, Dunlop covers 195/70R14 with the Sport Classic, and Maxxis plus BFGoodrich cover 205/70R14 with several sidewall treatments. Brand choice therefore depends first on the tire size your BMW uses.
The main dividing line is not simply brand preference but whether your car needs a standard 14-inch radial or a metric TRX radial. Once the size is confirmed, the available brands narrow naturally. If you own a 205/70R14 application, you have the broadest brand and appearance range. If you own a TRX application, Michelin remains the defining choice because that system is tied to a very specific wheel-and-tire format.
What is the difference between BFGoodrich Radial T/A and BFGoodrich Silvertown Radial for the 1986 BMW?
In 205/70R14 for a 1986 BMW, the BFGoodrich Radial T/A comes with raised white letters, an S speed rating of 112 mph, a 1,433-pound load figure at 35 psi, and a recommended rim-width span of 5.00 to 7.00 inches. The BFGoodrich Silvertown Radial appears in redline and dual-redline versions, also carries a 1,433-pound load figure at 35 psi, and uses a slightly different rim-width span of 5.50 to 7.50 inches.
That makes the choice less about basic fitment than about appearance and wheel compatibility. A Radial T/A gives a period performance look associated with raised-letter tires, while the Silvertown versions aim more at a distinctive vintage sidewall presentation. If your BMW runs 205/70R14, compare your wheel width against the specific tire's approved range before selecting between those sidewall styles.
Fitting & Setup
What rim width do 1986 BMW tires require?
Rim-width guidance is tire-size specific on 1986 BMW applications where that information is available. The 205/70R14 size fits rims from 5.00 to 7.00 inches in the Maxxis and BFGoodrich Radial T/A versions, while the BFGoodrich Silvertown Radial versions call for 5.50 to 7.50 inches. The 200/60R390 TRX tire uses 120mm, 135mm, and 165mm metric wheel widths, and the 220/55R390 TRX tire uses 135mm, 150mm, and 180mm metric widths.
Those ranges matter because sidewall style alone does not guarantee the same wheel-width tolerance from one tire to another. A 205/70R14 owner should confirm the actual wheel width before choosing among the available sidewall treatments, and a TRX owner should verify the wheel's metric marking rather than assuming an inch conversion. Matching the tire to the wheel correctly is one of the easiest ways to avoid fitment frustration.
Do 1986 BMW tires require inner tubes?
The TRX sizes used on 1986 BMW applications are tubeless in the Michelin versions, with both 200/60VR390 and 220/55VR390 marked TL. The 195/65VR14 Michelin tire is also marked TL. On the other 14-inch radial sizes, tube requirement is not presented in the same way on every product, so the final answer can vary by product and by wheel condition.
For a buyer, that means tube fitment should be confirmed from the tire's sidewall marking and from the wheel itself rather than assumed from size alone. Original BMW alloy wheels intended for tubeless service are a different situation from older repaired or heavily refinished rims. If your 1986 BMW has TRX tires, the available Michelin versions are already tubeless, but the valve stems and bead surfaces still deserve careful inspection.
Can the original 1986 BMW wheels be used with all tire sizes?
Original 1986 BMW wheels can be used only with the tire sizes that match their diameter system. The 14-inch wheel applications take 195/65R14, 195/70R14, or 205/70R14 depending on model, while the TRX wheel applications take 200/60R390 or 220/55R390 depending on model. A 390mm TRX wheel is not the same as a conventional inch-based rim and cannot be treated as interchangeable.
That distinction is especially important on cars such as the 524td, 528e, 635CSi, 735i, and L7, where either standard or TRX fitments may appear depending on the wheel package fitted to the car. Before buying tires for a 1986 BMW with uncertain wheel history, inspect the wheel stamping or measure carefully. Many fitment mistakes happen because the car's current wheels differ from what the owner expects.
Maintenance, Storage & Longevity
How should I store a 1986 BMW when the tires are fitted?
A stored 1986 BMW should be kept out of direct sunlight, away from electric motors or other ozone sources, and on a clean, dry surface. Proper inflation matters during storage, and moving the car periodically helps reduce flat-spotting. Because every size used on 1986 BMW applications here is radial, long static storage is generally easier on the tread profile than with older bias-ply designs, but age and environment still affect the rubber.
For seasonal or long-term storage, many owners either roll the car occasionally or place it on stands to reduce sustained load on one contact patch. The spare deserves the same attention as the four road tires, especially on a BMW that may see touring use after long dormant periods. A cool, stable environment is one of the best ways to preserve both sidewall appearance and overall service life.
How long do tires on a 1986 BMW typically last?
On a collector-driven 1986 BMW, age usually matters more than mileage. A sensible rule is to begin evaluating tires closely once they reach roughly five to seven years of service and to treat around ten years as a point where replacement deserves serious consideration regardless of tread depth. The DOT date code on the sidewall is the best starting point for that age check.
Many 1986 BMW cars spend long periods parked, which can make old tires look usable even when the rubber has hardened or the internal structure has aged. A low-mileage TRX tire or a lightly used 14-inch radial should not be judged by tread alone. If the date code, storage history, or visible condition raises doubts, replacement is usually a wiser move than trying to stretch service life further.
How often should tires on a 1986 BMW be inspected?
Tires on a 1986 BMW should be inspected before every drive and again before any longer trip. Check for sidewall cracking, tread separation, irregular wear, punctures, bulges, and pressure loss. On tubeless TRX and standard radial applications alike, valve stems and bead areas deserve attention because age-related leaks often begin there before they become obvious.
A brief visual check before a weekend drive can prevent a much bigger issue on the road, especially with a car that is not used daily. For touring or event travel, inspect the spare and confirm it still holds pressure. If your BMW has sat for several months, include a slow roll-and-look inspection so you can spot flat spots, weathering, or wheel-seat issues before heading onto the highway.
Restoration & Authenticity
What tires were originally fitted to the 1986 BMW 325?
A 1986 BMW 325 used radial tires, and the fitment here is 195/65R14 on 14-inch wheels. That aligns with the period, because radial construction had long become the standard for BMW passenger cars by the mid-1980s. A blackwall radial is the natural visual and functional match for this model family, while brand choice today depends on what is available in the correct size rather than on a broad assumption about original supplier.
For a restoration-minded owner, the most important goal is getting the size, wheel diameter, and overall appearance right for the exact car. If your 1986 BMW 325 has unusual market-specific equipment or aftermarket wheel history, compare the car against factory literature or consult a BMW marque specialist. That extra step is worthwhile because originality on 1980s European cars often comes down to subtle wheel-and-tire details.
Does correct tire fitment matter for showing a 1986 BMW?
Correct tire fitment does matter when showing a 1986 BMW, especially at marque-focused events where authenticity is judged closely. Size, wheel-diameter system, construction, and sidewall appearance all influence how correct the car looks. A TRX-equipped car wearing conventional inch-based tires would be an obvious mismatch, and a sidewall treatment that feels out of character for a late-1980s BMW can stand out just as quickly.
Even when a car is not being judged at concours level, the right tire helps preserve the visual balance BMW intended for the E30, E28, E24, or E23 platform. Owners aiming for show accuracy should confirm whether the car originally carried standard 14-inch wheels or metric TRX wheels, then choose the matching size and a sidewall style that fits the period. Marque clubs remain the best source for event-specific judging expectations.
What is the difference between Michelin MXV3-A and Michelin TRX-B for the 1986 BMW?
For a 1986 BMW, the Michelin MXV3-A and Michelin TRX-B serve different wheel systems rather than competing for the same rim. The MXV3-A appears in 195/65VR14 for 14-inch applications, while the TRX-B appears in 200/60VR390 and 220/55VR390 for BMW's metric TRX wheels. The TRX-B versions are tubeless blackwalls, with the 200/60VR390 carrying a V rating and the 220/55VR390 carrying a W rating.
From a restoration standpoint, the important distinction is preserving the wheel-and-tire system the car was built around. If your BMW still wears TRX wheels, the TRX-B is the authentic path because a conventional 14-inch tire cannot substitute for a 390mm metric fitment. If the car uses standard 14-inch wheels, the MXV3-A fits that conventional setup. The two belong to different BMW fitment stories, not simply different tread designs.
Safety & Road Use
Are 1986 BMW tires safe for highway driving?
1986 BMW tires can be suitable for highway driving when they are the correct size, in sound condition, and used within their speed and load limits. The speed-rated products here include V-rated options to 149 mph in 195/65R14, 195/70R14, and 200/60R390, an S-rated 205/70R14 option to 112 mph, and a W-rated 220/55R390 option to 168 mph. Those ratings are well above ordinary U.S. highway speeds.
On a 1986 BMW, tire condition usually matters more than the printed top-speed ceiling for normal road use. Suspension wear, alignment, brake condition, and the age of the rubber often have a greater effect on stability and confidence than raw speed rating alone. For any longer highway trip, make sure the tires are fresh, properly inflated, and matched to the wheel system the car actually uses.
What inflation pressure should I use for 1986 BMW tires?
Inflation pressure for a 1986 BMW should follow the car's factory recommendation first, then be checked against the individual tire's own rated limits. Two 205/70R14 options carry a maximum load of 1,433 pounds at 35 psi, and the 195/70R14 Dunlop carries a maximum load of 1,356 pounds. Those figures are tire capacity references, not a blanket instruction to run every 1986 BMW at the same pressure.
The right pressure depends on the exact BMW model, tire size, loading condition, and whether the car is being driven solo or with passengers and luggage. A 14-inch 3 Series, a TRX-equipped 5 Series, and a larger 7 Series should not be treated identically. Start with the factory pressure guidance for your specific model, then confirm that your chosen tire's pressure and load limits fit the intended use.
What should I check before taking a 1986 BMW on a longer drive?
Before a longer trip in a 1986 BMW, inspect all five tires for cracking, cuts, bulges, embedded debris, irregular tread wear, and correct cold inflation pressure. Verify that the spare is usable and that the valve stems are in good condition. If the car uses TRX wheels, confirm that the tires are the correct 390mm metric size rather than relying on a quick visual impression.
Tires are only one part of a proper pre-drive check on a car of this age, but they are the easiest problem area to overlook when a vehicle has been driven infrequently. Add a brief road test for vibration or pull, and look over the brakes, belts, fluids, and cooling system before setting off. A well-prepared 1986 BMW can still be an excellent road car, but preparation matters more than confidence alone.
