2002 Infiniti Tire Fitment Guide

The 2002 Infiniti G20 uses 195/60R15, 195/65R15, or 205/50R16 depending on application. The 2002 Infiniti I35 uses 215/55R17 or 225/50R17. The 2002 Infiniti Q45 uses 225/55R17 or 245/45R18. All of these are radial sizes, but they do not share one universal rim diameter across the lineup, since 15-inch, 16-inch, 17-inch, and 18-inch fitments all appear within the same year and make.

That means the right starting point is always your exact model, then the wheel diameter already on the car. Rim width also matters once you narrow it down: 195/60R15 products run around 5.5 to 7 inches, 205/50R16 around 5.5 to 7.5, 215/55R17 around 6 to 7.5, 225/50R17 around 6 to 8, 225/55R17 around 6 to 9, and 245/45R18 around 7.5 to 9. If your Infiniti has replacement wheels, confirm the wheel size before choosing a tire.

On a 2002 Infiniti, 195/60R15 is a modern metric radial code. The 195 is the nominal section width in millimeters, 60 is the aspect ratio, R means radial construction, and 15 is the wheel diameter in inches. Within the 2002 Infiniti range, that size belongs to the G20 and mounts on 15-inch wheels.

The practical value of decoding that size is that it keeps you from confusing it with the G20’s other 15-inch option, 195/65R15, which uses the same wheel diameter but a taller profile. It also separates 15-inch G20 fitments from the model’s 16-inch option, 205/50R16. If you are comparing replacements, make sure the sidewall and overall profile on the car match the size you plan to use, not just the model badge.

No. The 2002 Infiniti lineup is clearly split by model. G20 fitments stay in 15-inch and 16-inch territory, the I35 uses 17-inch sizes, and the Q45 uses either a 17-inch or 18-inch fitment. Even when two models share the same rim diameter, the tire size itself still changes, so there is no single all-model 2002 Infiniti size.

That affects how you search. If you know only that you have a 2002 Infiniti, you are still too broad to choose a tire with confidence. Identifying the model gets you close, and confirming the exact wheel size and current sidewall marking gets you the rest of the way. That approach is especially important on cars that may have had factory optional wheels or later wheel swaps during their service life.

Sidewall style varies quite a bit across 2002 Infiniti sizes. The 195/60R15 used on some G20 applications is available in wide whitewall, RWL, redline, and blackwall form. The 225/55R17 used on some Q45 applications is available in blackwall and wide whitewall. The performance-oriented 16-inch, 17-inch, and 18-inch metric sizes otherwise stay largely in blackwall form.

For a 2002 luxury or sport sedan, blackwall is the most era-appropriate visual choice in most cases. Whitewalls and redlines are specialty looks that can change the personality of the car, even when the size is correct. If appearance matters as much as fitment, decide early whether you want a factory-style late-model presentation or a more custom visual statement before narrowing down the tire itself.

BFGoodrich appears across nearly the entire 2002 Infiniti size range, covering 15-inch through 18-inch applications in both specialty and performance-oriented series. Michelin is available in 195/60R15 for the G20, and Nitto appears in 225/50R17 and 245/45R18 sizes for I35 and Q45 fitments. Brand choice is therefore broadest in the more common 17-inch and 18-inch performance sizes.

That spread gives owners different ways to prioritize the car. A G20 owner may be balancing a standard blackwall replacement against a more stylized whitewall or redline option, while an I35 or Q45 owner is more likely comparing blackwall performance radials in the correct size. Once you have the proper size confirmed, brand becomes a matter of sidewall appearance, speed rating, and intended driving character rather than simple fitment.

For 2002 Infiniti applications where both appear, such as 225/50R17 and 245/45R18, both are blackwall radial choices with W-rated sizing in the 225/50R17 fitment. In 245/45R18, the BFGoodrich g-Force COMP-2 A/S carries a W rating while the Nitto NT555 G2 also appears in an XL 100W version. Rim-width support is similar, with 225/50R17 covering roughly 6 to 8 inches and 245/45R18 covering about 7.5 to 9 inches.

The takeaway is that both series fit the same general wheel-width envelope in those sizes, so the decision usually comes down to the exact size on the car and the product character you want from that specific series. A buyer comparing them should look closely at load index, any XL marking, and the wheel width already on the car. Those details matter more than brand name alone when you are matching a later-model Infiniti sedan.

Rim width depends on the exact size used on your 2002 Infiniti. The 195/60R15 fits roughly 5.5 to 7 inches, 205/50R16 fits about 5.5 to 7.5 inches, 215/55R17 fits about 6 to 7.5 inches, 225/50R17 fits about 6 to 8 inches, 225/55R17 fits about 6 to 9 inches, and 245/45R18 fits about 7.5 to 9 inches. Those ranges are broad enough that wheel choice still matters even when the tire size is correct.

That is especially important on cars with aftermarket wheels, because a tire can be right for the model yet wrong for the specific wheel width. Before committing to any replacement, compare the wheel width on the car with the acceptable range for that size. If your Infiniti has non-stock wheels, this checkpoint is just as important as matching the sidewall size itself.

The 2002 Infiniti range is built around modern radial sizes, and at least some products are clearly marked tubeless, such as the Michelin 195/60R15 88V TL. Other products in the same year-make range do not always carry an explicit tube marking in the size description, so tube status can vary by product presentation and should be checked on the tire itself. None of these fitments fall into an antique tube-type sizing pattern.

For most owners, the practical step is to treat the wheel-and-tire combination as a system rather than assuming all products in a size are identical. If the car still has original late-model wheels in sound condition, tubeless fitment is the norm for this era. If there is any doubt because of wheel condition, replacement wheels, or a specialty tire selection, confirm the tire’s sidewall marking before installation.

A stored 2002 Infiniti should be kept out of direct sunlight, away from electric motors, welders, battery chargers, and other ozone sources, and on a clean, dry surface. Maintain normal inflation pressure and move the car periodically so the same tread area is not carrying the load for months at a time. These are all radial tires, which generally resist flat-spotting better than older bias-ply designs, but long static storage can still affect ride quality.

If the car will sit through an entire season, many owners use tire cradles or place the vehicle on stands to reduce stress on the carcass, provided the suspension is supported appropriately. A breathable car cover and a stable indoor temperature help as well. Collector care is less about mileage and more about minimizing age, environmental exposure, and prolonged stationary loading.

On a 2002 Infiniti, age matters more than mileage alone, especially if the car is driven occasionally. A good rule is to begin evaluating the tires carefully around the five- to seven-year point and to treat the ten-year mark as a serious replacement threshold regardless of remaining tread. The DOT date code on the sidewall is the key reference for that timeline.

A low-mileage Q45 or G20 can still be riding on old rubber that looks acceptable at a glance but has hardened with time. Performance-oriented 17-inch and 18-inch radials also deserve closer age monitoring because owners may focus on tread depth and overlook sidewall condition. If your Infiniti still wears older tires from a prior ownership period, date checking should come before any spirited or extended driving.

Tires on a 2002 Infiniti should be inspected before every drive, with a more thorough check before any highway trip or long outing. Look for sidewall cracking, cuts, bulges, irregular wear, visible punctures, and any sign that the tire is losing pressure. Because these cars use modern radial sizes with different wheel diameters depending on model, any mismatch in wear from one axle to the other deserves attention.

A quick visual inspection catches far more problems than most owners expect, especially on cars that spend long periods parked. Add a pressure check when the car has been sitting, and inspect the spare as well if the trip is more than local. On an older luxury or sport sedan, tire condition is one of the easiest ways to improve confidence before driving without changing the character of the car.

Yes, when the correct size is used, the tire is in sound condition, and the speed rating matches the way the car will be driven. The 2002 Infiniti range here is built around modern radial sizes, with many 16-inch, 17-inch, and 18-inch options carrying W ratings, and one 245/45R18 option carrying a Y rating. A W rating corresponds to 168 mph, while a Y rating corresponds to 186 mph.

Those ceilings are far above normal U.S. highway use, so real-world safety usually depends more on age, condition, inflation, alignment, brakes, and suspension than on raw speed rating. A well-maintained G20, I35, or Q45 on fresh correct-size radials is better positioned for highway service than one riding on old or mismatched tires. Confirm the exact size and inspect the whole chassis before assuming the tire alone determines roadworthiness.

Inflation pressure for a 2002 Infiniti should follow the vehicle’s factory recommendation first, then be checked against the tire’s own load-and-pressure marking. Some examples in this fitment range include 195/60R15 at 1,190 pounds at 35 psi, 205/50R16 at 1,201 at 51 psi, 225/50R17 at 1,477 or 1,653 at 50 to 51 psi depending on product, 225/55R17 up to 1,819 at 50 psi, and 245/45R18 up to 1,764 at 50 psi.

Those figures are load-capacity references, not blanket instructions to inflate every 2002 Infiniti tire to the maximum number on the sidewall. The correct operating pressure for the car may be lower and is tied to the vehicle’s weight distribution, ride tuning, and intended use. Use the factory placard or owner’s manual as the baseline, then confirm that your chosen tire’s load rating supports that application.

Before a longer drive in a 2002 Infiniti, inspect each tire for cracking, bulges, cuts, punctures, uneven wear, and proper cold inflation pressure. Confirm that all four tires are the correct size for the model and wheel diameter, and make sure the spare is usable as well. On cars like the I35 and Q45, also verify that no low-profile tire has sidewall damage from prior curb or pothole impacts.

That tire check should be part of a broader pre-trip routine that includes brakes, fluids, belts, battery condition, and suspension health. A 2002 Infiniti is modern enough to feel effortless at speed, which can hide age-related issues until the car is already on the road. Taking a few minutes to inspect the tires and chassis beforehand does more for a relaxed trip than simply relying on tread depth alone.
