The 2004 Infiniti G35 sits in the early-2000s sport-luxury segment where sharp rear-drive handling, strong V6 performance, and distinctive coupe and sedan body styles made tire fitment part of the car’s character. On this model, the tire decision starts with the exact configuration, because the sedan uses 215/55R17 while the coupe can use a staggered 17-inch setup or a staggered 18-inch Performance Tire Package setup. All primary fitments are radial, so the focus is on matching the right size, wheel diameter, and front-to-rear pairing. From there, selection comes down to the correct series, brand, and road-use priorities without upsetting the intended stance or clearance.
Which Tire Size Is Right for The 2004 Infiniti G35
Five primary tire sizes apply to the 2004 Infiniti G35, and the right one depends on the exact sub-model and whether the car is a sedan, a standard coupe, or a coupe with the Performance Tire Package. Rim diameter is the first thing to confirm, since this G35 uses both 17-inch and 18-inch wheels. The coupe also uses staggered front and rear sizing, so identifying position and configuration matters before comparing tire choices.
225/50R17 is a metric radial size with a 225-millimeter section width, a 50-series profile, and fitment on a 17-inch rim. On the 2004 Infiniti G35, this size is used at the front of the standard coupe, so it is part of a staggered setup rather than a universal fitment across the model line. Available choices include BFGoodrich and Nitto in blackwall designs across g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2 lines. This size should be evaluated as a front-axle coupe fitment with attention to matching the rear tire and the actual wheel on the car.
235/50R17 is a metric radial size that uses a 235-millimeter section width, a 50-series aspect ratio, and a 17-inch wheel. For the 2004 Infiniti G35, it serves as the rear tire on the standard coupe, giving the car a wider rear fitment than the front. Product choice is more focused here, with BFGoodrich blackwall coverage in the g-Force Comp 2 AS series. This size needs to be matched to the correct rear wheel and paired with the proper front size rather than treated as a standalone fitment for every G35.
225/45R18 is a metric radial tire with a 225-millimeter width, a lower 45-series profile, and fitment on an 18-inch rim. On the 2004 Infiniti G35, this size is used at the front of the coupe equipped with the Performance Tire Package, so it belongs to the larger staggered wheel setup. BFGoodrich and Nitto offer blackwall options here in g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 series. This is the right size to consider only after confirming the car has the 18-inch performance package and the correct matching rear tire.
245/45R18 is a metric radial size combining a 245-millimeter section width, a 45-series profile, and an 18-inch rim diameter. It is the rear tire size for the 2004 Infiniti G35 coupe with the Performance Tire Package, making it the widest primary fitment used on this model range. Available blackwall choices come from BFGoodrich and Nitto across g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 lines. This size makes sense only in the proper rear performance-package position with the correct 18-inch wheel and matching front size.
Fit(s): Sedan, Sedan w/Sport-Tuned Suspension, X Sedan, and X Sedan w/Sport-Tuned Suspension
Construction: Radial|Rim: 17 in
215/55R17 is a metric radial size with a 215-millimeter section width, a 55-series profile, and a 17-inch rim diameter. On the 2004 Infiniti G35, this is the primary sedan fitment and it is shared across the standard sedan, sedan with sport-tuned suspension, G35 X sedan, and G35 X sedan with sport-tuned suspension. BFGoodrich offers blackwall choices in the g-Force Comp 2 AS and g-Force Phenom T/A series. This size is the key starting point for sedan owners, with the main decision shifting from fitment to tire series and intended driving use.
Sub-model fitment matters on the 2004 Infiniti G35 because the sedan and coupe do not use the same tire setup, and the coupe also uses different front and rear sizes. Confirming both the body style and wheel package is the quickest way to narrow the correct tire choice.

2004 Infiniti G35 Coupe Front
The standard 2004 Infiniti G35 coupe uses 225/50R17 at the front as part of a staggered radial setup. Tire selection here should stay focused on the correct front position and on maintaining a proper pairing with the coupe’s rear size.
The standard 2004 Infiniti G35 coupe uses 235/50R17 at the rear, wider than the front tire and tied to the 17-inch staggered arrangement. Choosing this size correctly means confirming the car is not the 18-inch Performance Tire Package version.
2004 Infiniti G35 Coupe w/Performance Tire Pkg. Front
The 2004 Infiniti G35 coupe with the Performance Tire Package uses 225/45R18 at the front. That lower-profile 18-inch fitment should be selected only after confirming the car’s larger wheel package and the matching rear tire size.
2004 Infiniti G35 Coupe w/Performance Tire Pkg. Rear
The 2004 Infiniti G35 coupe with the Performance Tire Package uses 245/45R18 at the rear in a staggered radial layout. Tire choice here centers on keeping the correct rear size and confirming the actual 18-inch wheel before comparing available series.
The 2004 Infiniti G35 sedan uses 215/55R17, giving sedan owners a more straightforward fitment path than the staggered coupe. With the size established, the decision becomes choosing among the available blackwall radial series for the car’s intended use.
The 2004 Infiniti G35 sedan with sport-tuned suspension also uses 215/55R17. That shared size keeps tire replacement simple, but wheel changes or suspension modifications should still be checked before moving beyond the standard fitment.
The 2004 Infiniti G35 X sedan uses the same 215/55R17 radial size as the other sedan configurations covered here. Selection can stay focused on the right tire series and wheel compatibility rather than sorting through multiple primary sizes.
2004 Infiniti G35 X Sedan w/Sport-Tuned Suspension
The 2004 Infiniti G35 X sedan with sport-tuned suspension continues with the 215/55R17 fitment. That consistency helps simplify replacement, though it is still worth checking the actual wheel and overall setup on any car that has been modified over time.
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.

Tire Size & Fitment
What tire size fits a 2004 Infiniti G35?
The 2004 Infiniti G35 uses several tire sizes depending on configuration. Sedan models use 215/55R17, the standard coupe uses 225/50R17 front and 235/50R17 rear, and the coupe with the Performance Tire Package uses 225/45R18 front and 245/45R18 rear.
The first step is confirming whether the car is a sedan or coupe, then checking whether it has 17-inch or 18-inch wheels. Coupe owners also need to verify front versus rear position because the car uses staggered sizing, and that affects how the tires should be replaced and matched.
What size rim does a 2004 Infiniti G35 use?
A 2004 Infiniti G35 uses either 17-inch or 18-inch rims, depending on the sub-model and wheel package. The sedan fitment is 17-inch, the standard coupe uses 17-inch front and rear wheels, and the coupe with the Performance Tire Package uses 18-inch front and rear wheels.
Checking rim diameter before choosing a tire is essential because the G35 does not use one universal wheel size across all versions. Reading the tire sidewall and confirming the actual wheel on the car helps avoid mixing 17-inch and 18-inch fitments, especially on vehicles that may have changed hands or been modified.
Why does the 2004 Infiniti G35 have more than one tire size?
The 2004 Infiniti G35 has more than one tire size because Infiniti used different setups for the sedan and coupe, and the coupe used staggered front and rear sizing. The Performance Tire Package also changes the coupe to an 18-inch front and rear combination with different tire dimensions.
That means tire selection is tied to the exact version of the car rather than the model name alone. Matching the correct size to the correct axle position preserves the intended wheel-and-tire relationship and helps prevent clearance, balance, and handling issues that can come from choosing by guesswork.
Choosing the Right Tire
What should I consider when choosing a 2004 Infiniti G35 tire?
Start with the exact factory-style size for the specific G35 configuration, then confirm whether the car uses a 17-inch or 18-inch wheel and whether it has a staggered coupe setup. All primary fitments for the 2004 Infiniti G35 are radial, so the main comparison is within the correct size rather than between construction types.
After fitment is confirmed, compare tire series, brand, rim-width specifications, and any load information that appears on the product. A sedan owner shopping 215/55R17 has a different decision than a coupe owner matching front and rear sizes, so choosing by configuration is more important than choosing by model name alone.
What brands offer tires for the 2004 Infiniti G35?
BFGoodrich and Nitto both offer tires for certain 2004 Infiniti G35 sizes, while some sizes are covered only by BFGoodrich in the current assortment. The available lineup includes blackwall radial choices across several performance-oriented series depending on whether the car uses 17-inch or 18-inch fitments.
Brand choice should still come after the correct size and wheel package have been confirmed. A wider selection appears in some coupe sizes than in others, so it helps to compare the exact tire size on the car first, then review which brand and series combinations are available within that fitment.
What tire series are available for the 2004 Infiniti G35?
The 2004 Infiniti G35 is covered by several radial tire series, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. Not every series appears in every size, so availability depends on the exact sedan or coupe fitment.
Series choice matters because it helps separate the product grid into more meaningful comparisons once size is settled. Coupe owners with staggered 17-inch or 18-inch setups should verify that both front and rear sizes are available in the series they want, while sedan owners can focus on the best match within 215/55R17.
Restoration & Appearance
Which tire should I choose for a period-style 2004 Infiniti G35?
A period-style 2004 Infiniti G35 should begin with the correct original-format radial size for the exact configuration, whether that is the sedan’s 215/55R17, the standard coupe’s 17-inch staggered pair, or the Performance Tire Package’s 18-inch staggered pair. Keeping the proper size and wheel diameter does the most to preserve the car’s intended look.
Since the available options are blackwall radials, the appearance decision is more about maintaining the right proportions than choosing among decorative sidewall treatments. Buyers pursuing a highly exact restoration presentation should also compare the car against original sales materials, marque references, or other model-specific historical sources before finalizing a tire choice.
Does correct tire fitment matter for a 2004 Infiniti G35 restoration?
Correct tire fitment matters on a 2004 Infiniti G35 restoration because the car’s stance and overall presentation change noticeably when the wrong size or wheel diameter is used. This is especially important on coupe models, where the staggered front and rear arrangement is part of the vehicle’s original visual and functional character.
Using the right size also helps keep the car visually balanced within the wheel openings and avoids mismatched front-to-rear proportions. Even on a driver-focused restoration, it is worth confirming whether the car retains its original wheel package or has moved to aftermarket wheels before choosing replacement tires.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Infiniti G35?
Yes, modifications can affect tire fitment on a 2004 Infiniti G35 even when the tire size sounds close to the original. Aftermarket wheels, changes in wheel width, altered offset, lowering, or suspension changes can all affect how a 17-inch or 18-inch tire sits within the fender and how much clearance remains.
That is especially important on staggered coupe setups, where front and rear tires already differ from one another. Any modified G35 should have its actual wheel dimensions, axle position, and clearance checked before replacement, rather than assuming the same size will behave the same way on a changed chassis.
What should I inspect before driving a 2004 Infiniti G35 on new tires?
Before driving a 2004 Infiniti G35 on new tires, inspect wheel condition, confirm the correct front and rear sizes, and verify that the tire bead seats properly on the wheel. It also helps to check for suspension wear, uneven previous tire wear, and any signs that alignment or ride-height issues affected the old setup.
A quick road-use check should also include tire pressure, lug torque, and visible clearance at full steering lock where applicable. Cars that sit for long periods deserve extra attention to aged rubber components, stored-wheel corrosion, and slow air loss so the new tires are not asked to compensate for other issues.
How often should tires on a 2004 Infiniti G35 be inspected?
Tires on a 2004 Infiniti G35 should be inspected regularly, with routine checks for pressure, tread wear, cuts, bulges, and sidewall damage. A performance-oriented car with staggered fitment can hide developing issues if only one axle is watched closely, so both ends of the car deserve equal attention.
Inspection becomes even more important when the car is driven infrequently or stored for long stretches. Looking over the tires before longer drives helps catch age-related cracking, flat spotting, and air-loss concerns early, while periodic checks of alignment and suspension condition can prevent uneven wear from shortening tire life.
