The 1986 BMW 735i comes from the E23 era, when BMW’s flagship sedan balanced executive comfort with the sharp road manners that helped define the brand in the 1980s. For tire selection, this car is unusual because the 735i Base can be found with either a conventional 205/70R14 radial or the millimetric 220/55R390 radial used with Michelin TRX-style wheel setups. That makes wheel confirmation the first step before choosing a tire. From blackwall touring-style choices to narrow whitewall, redline, dual-redline, raised white letter, and Michelin TRX options, appearance and wheel type both matter. A careful match keeps the car’s stance, character, and road-use readiness aligned with the actual setup on the car.
Which Tire Size Is Right for The 1986 BMW 735i
The 1986 BMW 735i uses two primary tire sizes, and the difference centers on wheel type rather than a simple styling preference. A conventional 14-inch wheel setup uses 205/70R14, while TRX-equipped cars use 220/55R390 on a millimetric wheel. Before selecting a tire, confirm which wheel diameter and wheel system are actually on the car, especially if it has been changed over the years.
The size 205/70R14 identifies a metric radial tire with a 205-millimeter nominal section width, a 70-series profile, and fitment for a 14-inch rim. On the 1986 BMW 735i, this is the conventional radial option and gives the buyer the broadest range of product and appearance choices. Available offerings include Maxxis, BFGoodrich, and Michelin, with sidewall treatments such as narrow whitewall, RWL, dual-redline, redline, and blackwall across series like Classic Whitewall MA-1, Radial TA, Silvertown Radial, and Michelin XWX. This size is the right path when the car has standard 14-inch wheels and the goal is to balance proper fitment with the preferred visual character.
The size 220/55R390 is a metric radial that uses a 220-millimeter nominal section width, a 55-series profile, and a 390-millimeter rim rather than a conventional inch-based wheel diameter. On the 1986 BMW 735i, this size belongs to the Michelin TRX-style wheel system, so it is not interchangeable with a 14-inch setup just because both are radial tires. The available product is a Michelin TRX-B blackwall, which keeps the car aligned with this distinctive millimetric wheel arrangement. This size should be chosen only after confirming that the car still wears TRX wheels and has not been converted to a standard inch-based package.
Sub-model fitment is straightforward here because the covered 1986 BMW 735i Base is the only sub-model, but tire choice still is not automatic. The important distinction is confirming whether the car has standard 14-inch wheels or the millimetric TRX wheel setup before selecting a size.

Best 1986 BMW 735i Tires for Sale
Available 1986 BMW 735i tires span conventional 205/70R14 radials from Maxxis, BFGoodrich, and Michelin, plus a Michelin TRX-B in 220/55R390. The main buying differences are wheel system, tire series, and sidewall appearance, with choices ranging from blackwall and narrow whitewall to redline, dual-redline, and RWL.
Common 1986 BMW 735i tire questions usually come down to wheel-system confirmation, correct size selection, TRX versus conventional radial fitment, sidewall appearance, and the checks worth making before putting a collector-era BMW back on the road.
Tire Size & Fitment
What tire size fits a 1986 BMW 735i?
A 1986 BMW 735i uses either 205/70R14 or 220/55R390, and both are radial tire sizes. The conventional size is 205/70R14 on a 14-inch wheel, while 220/55R390 belongs to the millimetric Michelin TRX wheel system.
The key step is confirming which wheels are actually on the car before ordering tires. Many older BMW sedans have been converted from TRX wheels to standard inch-based wheels over time, so the size on the sidewall and the wheel diameter both deserve a careful check.
What size rim does a 1986 BMW 735i use?
Rim size on a 1986 BMW 735i depends on which tire setup the car has. A 205/70R14 tire uses a 14-inch rim, while a 220/55R390 tire uses a 390-millimeter TRX rim rather than a conventional inch-based wheel.
That difference matters because a 390-millimeter wheel is its own system and should not be treated as the same as a 14-inch wheel. Checking the actual wheel markings, the tire sidewall, and the current wheel package prevents ordering a tire that matches the car in appearance but not in bead-seat diameter.
Does the 1986 BMW 735i Base use the same tire size?
The 1986 BMW 735i Base is the covered sub-model, and it can be found with either 205/70R14 or 220/55R390 radial tires. The difference comes from wheel setup, not from separate trim-level tire programs within the 735i name.
That means the right tire is determined by the wheels currently installed on the car. A Base model with standard 14-inch wheels should stay within the 205/70R14 range, while a Base model retaining TRX wheels needs the 220/55R390 size matched to that millimetric rim system.
Choosing the Right Tire
What should I consider when choosing a 1986 BMW 735i tire?
Start with the correct wheel system, because the 1986 BMW 735i may use either 205/70R14 or 220/55R390. Once the size is confirmed, the next considerations are construction consistency, intended use, sidewall appearance, and the product line that best suits the car’s presentation.
A standard-wheel car has the widest choice, including blackwall, narrow whitewall, redline, dual-redline, and RWL options in several radial series. A TRX-equipped car is a more specialized decision, so the buyer should focus on preserving the proper millimetric fitment and confirming wheel compatibility before comparing appearance details.
What sidewall styles are available for 1986 BMW 735i tires?
Sidewall choices for the 1986 BMW 735i vary by tire size. In 205/70R14, available styles include narrow whitewall, RWL, dual-redline, redline, and blackwall, while 220/55R390 is available as a blackwall Michelin TRX-B.
That variety makes sidewall appearance an important part of the decision on standard 14-inch cars, especially if the goal is a more formal, sporty, or restoration-oriented look. Sidewall style should be chosen only after the correct size and wheel type are confirmed, since appearance cannot overcome an incorrect wheel diameter.
What brands offer tires for the 1986 BMW 735i?
Tires for the 1986 BMW 735i are available from Maxxis, BFGoodrich, and Michelin, depending on size. The 205/70R14 fitment includes options from all three brands, while 220/55R390 is represented by Michelin through the TRX-B line.
Brand choice is only one part of the decision, because the available products also differ by tire series, sidewall treatment, and rim-width range. After confirming whether the car has standard wheels or TRX wheels, compare the remaining options by the look you want and the wheel specifications the tire is built to accommodate.
Restoration & Appearance
Which tire should I choose for a period-style 1986 BMW 735i?
A period-style 1986 BMW 735i tire choice starts with preserving the car’s actual wheel system. Cars on standard 14-inch wheels can use 205/70R14 in several visual styles, while cars retaining TRX wheels need the 220/55R390 Michelin TRX-B to stay with that distinctive millimetric layout.
After the size is settled, appearance becomes the next decision. Blackwall usually gives the most restrained executive-sedan look, while narrow whitewall, redline, dual-redline, or RWL can change the personality noticeably, so buyers seeking exact originality should compare their choice against period photos, marque references, or build-specific documentation.
How does tire construction affect the appearance of a restored 1986 BMW 735i?
Construction changes are less of an issue here because both primary fitments for the 1986 BMW 735i are radial. The bigger appearance difference comes from whether the car remains on a conventional 14-inch wheel setup or keeps the TRX wheel-and-tire system, along with the sidewall treatment chosen within 205/70R14.
That means restoration appearance is shaped more by wheel type and sidewall style than by a bias-ply versus radial decision. A blackwall presentation stays closest to a clean European luxury-sedan look, while stripe or lettered sidewalls create a more personalized period impression that should be matched to the car’s overall finish.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 BMW 735i?
Yes, modifications can affect tire fitment on a 1986 BMW 735i, especially because this car may already have been converted between TRX and standard inch-based wheels. Aftermarket wheels, altered offsets, suspension changes, and body or fender modifications can all change what fits comfortably.
A car that now wears 14-inch wheels still needs the correct tire size and adequate clearance through steering and suspension travel. Wheel width, offset, and current ride height should all be checked before changing tires, since a size that works on one 735i setup may not suit another modified example.
What should I inspect before driving a 1986 BMW 735i on new tires?
Before driving a 1986 BMW 735i on new tires, inspect the wheels, valve stems, and current clearances, then confirm that the tires match the wheel system on the car. Tire pressure, lug fastener condition, and visible interference around the fenders and suspension are worth checking before the first serious drive.
A short initial road test helps confirm that the car tracks properly and that there is no rubbing during turning or suspension movement. It is also wise to look over the alignment, brakes, and suspension condition, because an older luxury sedan can have wear issues that affect how new tires behave.
How should 1986 BMW 735i tires be maintained?
Tires on a 1986 BMW 735i should be maintained with regular pressure checks, visual inspections, and careful storage habits if the car is not driven often. Owners should watch for cracking, bulges, cuts, uneven tread wear, and gradual air loss, especially on collector vehicles that spend long periods parked.
Keeping the car away from prolonged heat, direct sunlight, moisture, and ozone sources helps preserve tire condition between drives. It also makes sense to inspect the tires before any longer outing, since age-related deterioration can appear on low-mileage collector cars even when tread depth still looks acceptable.
