The 1999 Infiniti G20 sits in the era when compact sport sedans balanced everyday comfort with a more European-style driving feel. Buyers looking after one today often want to preserve that clean late-1990s character while still making sensible choices for modern road use. Tire fitment depends on the exact version, with the G20 Base using 195/65R15 and the G20 T using 195/60R15, both in radial construction on 15-inch rims. Within those sizes, the real choice can shift toward sidewall style, brand character, and whether the goal is a stock-looking sedan, a sportier presentation, or a more restoration-minded appearance. Confirming the sub-model first keeps the selection process on track.
Which Tire Size Is Right for The 1999 Infiniti G20
The 1999 Infiniti G20 uses two different tire sizes, and the right one depends on the exact sub-model. Both are radial tires for 15-inch rims, but the Base and T do not share the same size, so identifying the car correctly comes before comparing brands, sidewall styles, or product details.
A 195/65R15 tire uses a 195 millimeter nominal section width, a 65-series aspect ratio, radial construction, and a 15-inch rim diameter. On the 1999 Infiniti G20, this size belongs to the Base model and reflects a conventional modern metric radial format that is easy for most buyers to recognize. It carries a slightly taller profile than the G20 T size, so it should not be treated as interchangeable across both sub-models without checking the car itself. This is the size to focus on when the goal is maintaining the proper Base-model fitment before moving on to tire style and brand choice.
A 195/60R15 tire keeps the same 195 millimeter nominal width but uses a lower 60-series profile, still in radial construction for a 15-inch wheel. On the 1999 Infiniti G20, this size applies to the T sub-model and creates a different fitment path than the Base model. Available choices in this size include BFGoodrich and Michelin, with blackwall, wide whitewall, redline, and raised white letter sidewall treatments across Silvertown Radial, Radial TA, and Michelin Primacy 3 lines. This is the size to evaluate when the car is a G20 T and the buyer wants to balance correct fitment with appearance and intended use.
Sub-model fitment matters on the 1999 Infiniti G20 because the Base and T use different tire sizes. Both ride on 15-inch radial tires, but confirming the exact trim is the key first step before choosing a replacement.

1999 Infiniti G20 Base
The 1999 Infiniti G20 Base uses a 195/65R15 radial tire on a 15-inch rim. That makes the buying decision less about construction choice and more about staying with the correct Base-model size before comparing available tire styles and specifications.
The 1999 Infiniti G20 T uses a 195/60R15 radial tire on a 15-inch rim rather than the taller Base-model size. Tire selection here centers on confirming the T fitment first, then choosing among available brands, tire series, and sidewall presentations in that size.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Common 1999 Infiniti G20 tire questions usually come down to identifying the correct sub-model, confirming the 15-inch rim fitment, and deciding how much sidewall style or period-inspired appearance matters in the final selection.
Tire Size & Fitment
What tire size fits a 1999 Infiniti G20?
The 1999 Infiniti G20 uses two tire sizes depending on sub-model. The G20 Base uses 195/65R15, while the G20 T uses 195/60R15. Both are radial tire sizes built for 15-inch rims, so the key difference is the profile used on each version of the car.
That means the first step is identifying whether the car is a Base or a T before choosing a tire. Even though both sizes share the same rim diameter, they are not the same fitment. Checking the existing tire size, wheel setup, and vehicle trim helps avoid mixing the taller Base size with the lower-profile T size.
What size rim does a 1999 Infiniti G20 use?
The tire fitments used on the 1999 Infiniti G20 are both built around a 15-inch rim diameter. The 195/65R15 size for the Base model and the 195/60R15 size for the T model each use a 15-inch wheel, so rim diameter stays consistent even though the tire profiles differ.
Rim diameter is only one part of fitment, so it should not be the only measurement checked before replacement. Wheel width and any changes from aftermarket wheels still matter, especially if the car has been modified. Matching the correct tire size to the right sub-model remains just as important as confirming the 15-inch rim itself.
Do all 1999 Infiniti G20 sub-models use the same tire size?
No. The 1999 Infiniti G20 Base uses 195/65R15, while the 1999 Infiniti G20 T uses 195/60R15. Both are radial tires for 15-inch rims, but the two sub-models do not share the same profile, so tire size selection changes with the exact version of the car.
That difference is important because a tire that is correct for one G20 sub-model should not automatically be assumed correct for the other. Buyers should confirm the trim, read the size already mounted on the car, and make sure the wheel setup has not been altered over the years before choosing replacement tires.
Choosing the Right Tire
What should I consider when choosing a 195/60R15 tire for a 1999 Infiniti G20?
Start with correct sub-model fitment, because 195/60R15 applies to the 1999 Infiniti G20 T. After that, compare radial construction details such as rim-width compatibility, sidewall style, tire series, and any load information shown for the tire. In this size, choices range from more modern blackwall styling to wide whitewall, redline, and raised white letter designs.
The right pick depends on how the car is used and how it should look. A G20 kept close to its late-1990s appearance may point one way, while a more customized or appearance-driven build may point another. It also helps to confirm that the wheel width falls within the tire's approved range before making a final choice.
What sidewall styles are available for 1999 Infiniti G20 tires?
For the 1999 Infiniti G20 T size of 195/60R15, available sidewall styles include blackwall, wide whitewall, redline, and raised white letter. Those choices all stay within radial construction, but they create very different visual results, from a subdued modern look to a stronger period-inspired or performance-style presentation.
Sidewall style should be chosen with the car's overall character in mind rather than as an isolated detail. A blackwall keeps the look understated, while redline, wide whitewall, or raised white letter tires draw more attention to the wheel opening. The practical step is making sure the appearance choice still matches the correct 195/60R15 fitment for the G20 T.
What brands offer tires for the 1999 Infiniti G20?
In the available 195/60R15 fitment for the 1999 Infiniti G20 T, tire choices include BFGoodrich and Michelin. The BFGoodrich offerings span Silvertown Radial and Radial TA lines with multiple sidewall treatments, while Michelin Primacy 3 appears as a blackwall radial option in the same size.
Brand alone should not make the decision. It is smarter to compare the tire's series, sidewall presentation, and wheel-width compatibility alongside the intended use of the car. Once the G20 sub-model and size are confirmed, the product differences become more meaningful than simply choosing a familiar brand name.
Restoration & Appearance
Which tire should I choose for a period-style 1999 Infiniti G20?
A period-style 1999 Infiniti G20 should start with the correct sub-model size, since the Base uses 195/65R15 and the T uses 195/60R15. From there, the choice becomes one of presentation. In the available G20 T size, options include blackwall, redline, wide whitewall, and raised white letter radial tires.
The most suitable tire depends on whether the goal is a restrained late-1990s sedan look or a more stylized appearance. Size comes first, appearance second. When exact originality matters, it is worth checking marque-specific references or period photos so the sidewall treatment supports the character of the car rather than overpowering it.
How does tire construction affect the appearance of a restored 1999 Infiniti G20?
For the 1999 Infiniti G20, the primary fitments are radial tires, so the main appearance differences come less from bias-ply versus radial construction and more from sidewall treatment and tire series. In 195/60R15, the visual range runs from blackwall to wide whitewall, redline, and raised white letter styles.
That makes construction a straightforward part of the decision, while style becomes the more visible choice on a restoration-minded car. A buyer trying to preserve a stock-like look will usually focus on subtle sidewall presentation, while a customized build may welcome a more dramatic treatment. Keeping the correct size remains the foundation of the finished look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1999 Infiniti G20?
Yes. Even though the 1999 Infiniti G20 uses 15-inch tire fitments from the factory size range covered here, aftermarket wheels, altered wheel width, suspension changes, or body modifications can change what works on the car. That matters even more because the Base and T already use different tire profiles from the start.
A modified G20 should be checked at the wheel and tire level rather than by model name alone. Verify the actual wheel diameter and width, then look at clearance around the strut, fender, and steering range. Using the proper sub-model size as a baseline helps, but a changed chassis or wheel setup can still alter the final fitment picture.
What should I inspect before driving a 1999 Infiniti G20 on new tires?
Before putting a 1999 Infiniti G20 back on the road with new tires, inspect the wheels for damage, confirm the installed size matches the correct Base or T fitment, and check general condition around the suspension and steering. Tire pressure should also be set correctly, and the tires should be examined for any visible damage after mounting.
A careful road-use check helps catch problems that a new tire alone will not solve. Look for uneven old wear patterns that may point to alignment or suspension issues, and make sure there is no rubbing at full steering lock. On a low-mileage collector car, it is also smart to inspect aging rubber components elsewhere in the chassis.
How often should tires on a 1999 Infiniti G20 be inspected?
Tires on a 1999 Infiniti G20 should be inspected regularly, especially if the car sees limited use, long storage periods, or seasonal driving. Routine checks should include tread condition, sidewall cracking, cuts, bulges, and any sign of slow air loss. Collector and secondary-use cars often need closer attention than daily drivers.
A simple visual check before drives and a more thorough inspection at service intervals can help prevent avoidable issues. Cars that sit for extended periods can age tires even when tread looks good, so appearance alone is not enough. Keeping the tires properly inflated and stored away from heat, sunlight, and ozone sources helps preserve them longer.
