1998 Mazda covered a broad slice of the market, from the practical Protege compact to the midsize 626 and the near-luxury Millenia. It was a year when Mazda balanced everyday drivability with the sharper steering feel and road manners that gave many of its cars a more enthusiast-friendly character than their rivals. Across 1998 Mazda models, tire sizing varies by model rather than carrying one shared fitment, with six radial sizes spread across three cars and four different rim diameters. The first step is to confirm whether you have a Protege, 626, or Millenia, then match the correct size and wheel diameter before narrowing your tire style preference.
Which Tire Size Is Right for Your 1998 Mazda
Six tire sizes are available for 1998 Mazda vehicles, and they vary by model rather than being shared across the full lineup. Every size here is a radial, so the real decision starts with identifying the correct model and wheel diameter first, then choosing the sidewall style and product character that best suits your car. Understanding that distinction before choosing a tire saves time and helps match the right product to the right Mazda.
Year(s): 1998|Fit(s): 626|Construction: Radial|Rim: 14 in
185/70R14 is a metric radial size with a 185-millimeter section width, a 70-series aspect ratio, and fitment for a 14-inch wheel. This 626-specific size is available from BFGoodrich, Avon, Dunlop, and Michelin in blackwall and wide whitewall versions, and speed ratings vary by product with H-rated choices to 130 mph and a V-rated Michelin option to 149 mph; the Michelin is marked TL for tubeless use. It suits a 626 owner who wants to stay with the smaller-wheel fitment for the model while choosing between a more factory-like blackwall look or a specialty whitewall presentation. Rim width recommendations in this size range from 4.5 to 6.5 inches depending on the tire.
Year(s): 1998|Fit(s): 626|Construction: Radial|Rim: 15 in
205/60R15 is a metric radial size with a 205-millimeter section width, a 60-series aspect ratio, and fitment for a 15-inch wheel. This 626-specific size is available from Michelin, American Classic, Coker Classic, and BFGoodrich in blackwall, wide whitewall, and raised white letter styles, and speed ratings vary by product with an S-rated BFGoodrich at 112 mph and a W-rated Michelin at 168 mph; the Michelin is marked TL for tubeless use. It is the larger-wheel 626 choice for owners who want to confirm whether their car uses the 15-inch fitment before deciding between a contemporary blackwall appearance and more stylized sidewall treatments. Rim width recommendations run from 5.5 to 7.5 inches where specified.
Year(s): 1998|Fit(s): Millenia|Construction: Radial|Rim: 15 in
205/65R15 is a metric radial size with a 205-millimeter section width, a 65-series aspect ratio, and fitment for a 15-inch wheel. This Millenia-specific size comes from BFGoodrich in wide whitewall and redline versions, with both products sharing the same load capacity and pressure marking. It fits a Millenia owner who has confirmed the 15-inch wheel package and wants a specialty sidewall treatment that changes the car's visual character more than its basic fitment. Recommended rim width for these tires is 5.5 to 7.5 inches.
Year(s): 1998|Fit(s): Millenia|Construction: Radial|Rim: 16 in
215/55R16 is a metric radial size with a 215-millimeter section width, a 55-series aspect ratio, and fitment for a 16-inch wheel. This Millenia-specific size is available from BFGoodrich and American Classic in blackwall, redline, and wide whitewall forms, and the BFGoodrich carries a W speed rating with a 168 mph ceiling. It is the correct path for Millenia models using the 16-inch fitment, especially if you are choosing between a more contemporary performance-oriented blackwall and a custom or period-inspired sidewall look. American Classic gives a recommended rim width range of 5.5 to 7.5 inches in this size.
Year(s): 1998|Fit(s): Protege|Construction: Radial|Rim: 13 in
175/70R13 is a metric radial size with a 175-millimeter section width, a 70-series aspect ratio, and fitment for a 13-inch wheel. This Protege-specific size is available from Avon as a blackwall radial, and it carries an H speed rating with a 130 mph ceiling. It suits a Protege owner who has confirmed the smaller-wheel fitment and wants a clean, understated appearance that stays close to the compact car's original character. Recommended rim width for this size is 4.5 to 6.0 inches.
Year(s): 1998|Fit(s): Protege|Construction: Radial|Rim: 14-in rim
185/65R14 is a metric radial size with a 185-millimeter section width, a 65-series aspect ratio, and fitment for a 14-inch wheel. This Protege-specific size uses a 14-inch wheel and gives the car its alternate fitment within the 1998 compact Mazda range. It is the size to choose only after confirming that your Protege is equipped for the 14-inch setup rather than the 13-inch option. Matching the actual wheel diameter on the car is the key step before moving on to tire style and brand selection.
Three Mazda models are covered for 1998: the Protege, 626, and Millenia. Tire size changes by model, and each model also spans more than one wheel diameter, so year and make alone are not enough to choose correctly. Select your model below to narrow the fitment history and see the tire options that match that specific car.
1998 Mazda 626
The 1998 Mazda 626 was Mazda's midsize family sedan, positioned to blend everyday practicality with a more responsive feel than many mainstream rivals. Its tires mount on either 14-inch or 15-inch wheels depending on the version, so confirming the wheel package is the first step before choosing a replacement size.
The 1998 Mazda Millenia served as Mazda's premium sedan, with a more upscale mission and a smoother, more refined presentation than the brand's mainstream cars. Its fitments use either 15-inch or 16-inch wheels, making wheel diameter confirmation especially important before narrowing down sidewall style or brand.
The 1998 Mazda Protege was a compact sedan known for tidy proportions, light weight, and the crisp road manners that helped separate it from many economy-car competitors. Its tires fit either 13-inch or 14-inch wheels, so the compact Mazda buyer needs to verify the wheel diameter on the car before selecting a tire size.
Fifteen products are available across six tire sizes for 1998 Mazda vehicles. 185/70R14 has five radial choices from BFGoodrich, Avon, Dunlop, and Michelin in blackwall and wide whitewall; 205/60R15 has four from Michelin, American Classic, Coker Classic, and BFGoodrich in blackwall, wide whitewall, and RWL; 205/65R15 has two BFGoodrich radials in wide whitewall and redline; 215/55R16 has three from BFGoodrich and American Classic in blackwall, redline, and wide whitewall; 175/70R13 has one Avon blackwall radial. Confirm your size first, then check the individual tire's speed rating and tubeless marking where applicable.
Radial Tires

These answers sort out which 1998 Mazda model uses which tire size, how the metric radial codes break down, what sidewall styles and brands exist across the range, and what to inspect before putting a lightly used collector-era Mazda back on the road.
Size Basics & Fitment
What tire sizes fit 1998 Mazda vehicles?
1998 Mazda vehicles use six sizes across three models. The 626 uses 185/70R14 or 205/60R15, the Millenia uses 205/65R15 or 215/55R16, and the Protege uses 175/70R13 or 185/65R14. Those sizes do not interchange across the full 1998 Mazda range, and the rim diameters span 13, 14, 15, and 16 inches depending on the model and wheel package.
That means the first job is identifying the exact model and then matching the actual wheel diameter on the car. Within several models, two sizes were used from the factory depending on trim or wheel package, so a quick check of the sidewall already on the car or the wheel itself can prevent ordering the right tire for the wrong Mazda.
What does 185/70R14 mean on a 1998 Mazda tire?
On a 1998 Mazda, 185/70R14 is a metric radial size. The 185 is the nominal section width in millimeters, 70 is the aspect ratio, R means radial construction, and 14 is the wheel diameter in inches. In the 1998 Mazda range, that size belongs to the 626 and fits a 14-inch wheel.
Reading the code correctly helps you separate the tire's dimensions from the car's model name or trim. It also tells you immediately that a 185/70R14 cannot be substituted onto a 15-inch wheel without changing the wheel itself, which is why confirming the wheel diameter matters just as much as confirming that you own a 1998 Mazda 626.
Do all 1998 Mazda models use the same tire size?
No. 1998 Mazda models do not share one universal tire size. The Protege, 626, and Millenia each use their own pair of metric radial sizes, and each model can appear with two different wheel diameters. A 626, for example, uses 14-inch or 15-inch fitments, while a Millenia uses 15-inch or 16-inch fitments.
That model-by-model variation is normal for late-1990s Mazda cars because the lineup ranged from compact to premium sedan. If you know only the year and make, you are still one step short of a confident tire choice. Identifying the model, then checking the sidewall or wheel diameter on the car, is the cleanest way to narrow it down.
Buying the Right Tire
What sidewall styles are available for 1998 Mazda tires?
1998 Mazda tire options cover a wider visual range than many buyers expect. Blackwall choices appear in 175/70R13, 185/70R14, 205/60R15, and 215/55R16, while wide whitewall versions appear in 185/70R14, 205/60R15, 205/65R15, and 215/55R16. Redline versions are available in 205/65R15 and 215/55R16, and raised white letters appear in 205/60R15.
For an original late-1990s Mazda look, blackwall tires are the most natural visual match. Whitewalls, redlines, and raised white letters shift the car toward a custom, nostalgic, or period-mixed presentation, which can be exactly the goal on a personalized street car. The right choice depends less on fitment than on how faithful you want the finished car to remain to its era.
What brands make tires for 1998 Mazda vehicles?
1998 Mazda tire sizes are covered by BFGoodrich, Avon, Dunlop, Michelin, American Classic, and Coker Classic. Brand coverage varies by size: 185/70R14 has BFGoodrich, Avon, Dunlop, and Michelin; 205/60R15 has Michelin, American Classic, Coker Classic, and BFGoodrich; 205/65R15 has BFGoodrich; 215/55R16 has BFGoodrich and American Classic; and 175/70R13 has Avon.
That spread gives a Mazda owner several ways to approach the same car. Some brands lean toward clean blackwall touring or sport presentation, while others focus on specialty whitewall, redline, or raised-letter looks that change the car's personality. Once the correct size is confirmed, the brand decision becomes more about sidewall style, speed rating, and intended use than basic fitment.
What is the difference between Michelin Primacy 3 and BFGoodrich Radial T/A for a 1998 Mazda 626?
For a 1998 Mazda 626 in 205/60R15, the Michelin Primacy 3 is a blackwall radial marked 91W TL, while the BFGoodrich Radial T/A is a raised white letter radial marked 90S. The Michelin fits 5.5- to 7.5-inch rims and carries a W speed rating with a 168 mph ceiling. The BFGoodrich also fits 5.5- to 7.5-inch rims, carries a 1,301-pound load figure at 35 psi, and uses an S speed rating with a 112 mph ceiling.
That makes the choice less about wheel fit and more about appearance and product character. The Michelin keeps a more understated late-model look with a higher speed rating and tubeless marking, while the Radial T/A gives the 626 a much more overt performance-era visual with raised white letters. Either way, the size must still match the 15-inch 626 fitment.
Fitting & Setup
What rim width do 1998 Mazda tires require?
Rim width recommendations vary by size on 1998 Mazda vehicles. 175/70R13 fits 4.5- to 6.0-inch rims, 185/70R14 ranges from 4.5 to 6.5 inches depending on the tire, 205/60R15 fits 5.5- to 7.5-inch rims, 205/65R15 fits 5.5- to 7.5-inch rims, and 215/55R16 fits 5.5- to 7.5-inch rims where specified. Each size should be matched to the wheel it was intended for rather than treated as broadly interchangeable.
Rim width matters because the same nominal tire size can behave differently if the wheel is too narrow or too wide. Before choosing a brand or sidewall style, confirm the wheel diameter and measure the wheel width if there is any doubt, especially on a car with aftermarket wheels. That step keeps the tire within its intended profile and mounting range.
Do 1998 Mazda tires require inner tubes?
Most 1998 Mazda tire options here are radial passenger-car tires intended for modern-style wheel fitment, and some products are explicitly marked TL for tubeless use, including the Michelin XAS in 185/70R14 and Michelin Primacy 3 in 205/60R15. Other products in the same general year-make range are not marked the same way on the sidewall description, so tube status can vary by product rather than by size alone.
The practical move is to check the exact sidewall marking on the tire you choose and make sure it matches the wheel you plan to use. A late-1990s Mazda normally points you toward tubeless passenger-car fitment, but the final call still belongs to the tire's own construction and marking, not to the model year by itself.
Maintenance, Storage & Longevity
How should I store a 1998 Mazda when the tires are fitted?
A stored 1998 Mazda should be kept out of direct sunlight and away from ozone-producing equipment such as electric motors, battery chargers, welders, and some shop compressors. Clean, dry flooring and stable temperatures help preserve both tread and sidewall rubber. Radial tires usually resist flat-spotting better than older bias-ply designs, but they still age from heat, UV exposure, and long periods of inactivity.
If the car sits for extended stretches, move it periodically so the tire carcass is not carrying load in the same spot for months at a time. Many owners also keep the car at proper inflation during storage and use stands only when the broader restoration plan calls for it. Good storage habits matter as much on a lightly driven 1998 Mazda as they do on an older collector car.
How long do tires on a 1998 Mazda typically last?
On a 1998 Mazda that sees limited use, tire age usually matters more than tread wear. A good rule is to begin evaluating condition carefully once tires reach the five- to seven-year range and to consider replacement as they approach ten years, even if they still look serviceable. The DOT date code on the sidewall is the best way to establish actual age.
Collector and hobby cars often fool owners because they accumulate miles slowly and keep deep tread for years. Rubber can still harden, crack, or lose flexibility long before the tread is worn out. If your 1998 Mazda is driven only on weekends or to events, age-based inspection is the right approach rather than waiting for mileage alone to dictate replacement.
How often should tires on a 1998 Mazda be inspected?
Tires on a 1998 Mazda should be inspected before every drive and again before any extended road trip. Look for sidewall cracking, cuts, bulges, irregular wear, and any sign that a tire is losing pressure. On cars using tires with explicit tubeless markings, valve stem condition still matters just as much as tread and sidewall condition.
That quick inspection only takes a minute and often catches problems before they become roadside failures. A car that sits for long periods can develop issues that are not obvious from a distance, including aged rubber, underinflation, or sidewall weathering. Making tire checks part of every outing is one of the simplest ways to keep a 1998 Mazda dependable and enjoyable.
Safety & Road Use
Are 1998 Mazda tires safe for highway driving?
Yes, 1998 Mazda tire options here are modern radial designs, and several carry clear highway-capable speed ratings. H-rated examples such as the Avon and Dunlop reach 130 mph, the Michelin XAS in 185/70R14 reaches V rating at 149 mph, and the Michelin Primacy 3 and BFGoodrich g-Force Sport COMP-2 reach W rating at 168 mph. The BFGoodrich Radial T/A in 205/60R15 is S rated to 112 mph.
In real use, the car's condition matters at least as much as the tire's letter rating. A 1998 Mazda with healthy suspension, brakes, alignment, and correct inflation can use these tires confidently for normal road driving, but the safest limit is always the lower of the tire's rating, the vehicle's mechanical condition, and the conditions on the road.
What inflation pressure should I use for 1998 Mazda tires?
Inflation pressure on a 1998 Mazda should follow the vehicle's factory recommendation first, then be checked against the tire's own maximum rating where it appears on the sidewall. Some of these tires include clear load-and-pressure figures, such as 185/70R14 at 1,201 pounds at 35 psi, 205/60R15 options at 1,301 pounds at 35 psi or 1,521 pounds at 32 psi, 205/65R15 at 1,400 pounds at 35 psi, and 215/55R16 at 1,190 pounds at 35 psi.
Those figures are not a blanket instruction to run every tire at its maximum pressure. They tell you the load the tire can support at that pressure. For day-to-day use, start with the carmaker's pressure recommendation for your exact 1998 Mazda model and tire size, then fine-tune only within the tire maker's allowable range if needed for ride, wear, or load.
What should I check before taking a 1998 Mazda on a longer drive?
Before a longer drive in a 1998 Mazda, inspect each tire for cracking, cuts, bulges, uneven wear, and proper inflation, and make sure the spare is serviceable as well. Pay attention to valve stems and any sign of slow air loss, especially on a car that has spent long periods parked. Confirm that the tires on the car all match the correct size for the model and wheel diameter.
A tire check is only one part of the pre-trip routine on a car of this age. Brakes, cooling system health, belts, hoses, and suspension condition deserve the same attention before highway miles add heat and sustained load. If the tires are older, have been in storage, or show sidewall aging, address that before trusting the car for a long outing.
