The 2004 Pontiac GTO marked the return of a famous nameplate in a modern rear-wheel-drive performance coupe, blending contemporary power and road manners with unmistakable muscle-car expectations. Buyers looking at this exact model are usually balancing street use, stance, and appearance as much as outright fitment. The 2004 Pontiac GTO uses a 245/45R17 radial tire on a 17-inch rim, so the decision centers less on size and more on tire character within that fitment. Available choices include blackwall, raised white letter, and redline presentations across several radial series. That makes it important to match the tire not just to the wheel, but also to the car's intended look and use.
Which Tire Size Is Right for The 2004 Pontiac GTO
The 2004 Pontiac GTO uses one primary tire size: 245/45R17, a modern metric radial on a 17-inch rim. The covered GTO Base model uses that same fitment, so the main choice is not between different sizes, but between available radial tire types, sidewall styles, and street or specialty use within the correct size.
A 245/45R17 tire uses a 245-millimeter nominal section width, a 45-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2004 Pontiac GTO, this is a modern radial fitment that suits the car's contemporary muscle coupe layout and keeps selection focused on how the tire will be used rather than on decoding an older sizing system. Available choices include blackwall, raised white letter, and redline styles from brands such as BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster across several tire series. That makes this size a practical starting point for buyers weighing street appearance, general road use, or specialty drag-oriented use.
Tire fitment is straightforward for the covered 2004 Pontiac GTO sub-model. The Base model uses the same 245/45R17 radial fitment, so the focus shifts from identifying size differences to choosing the right tire type, sidewall treatment, and series for the way the car will be driven.

Tire Size & Fitment
What tire size fits a 2004 Pontiac GTO?
The 2004 Pontiac GTO uses a 245/45R17 tire size. It is a radial fitment and is the primary size used for the covered GTO configuration, including the Base model.
That makes size selection fairly straightforward, but the car still needs the correct 17-inch wheel setup to match the tire. It is smart to confirm the actual wheels on the car before choosing a tire, especially if a previous owner changed wheels or suspension height, because the real decision here is usually tire type, sidewall style, and intended use rather than a different primary size.
What size rim does a 2004 Pontiac GTO use?
The primary tire fitment for the 2004 Pontiac GTO uses a 17-inch rim diameter. That matches the 245/45R17 tire size, where the final number identifies the wheel diameter the tire is built to mount on.
Rim diameter is only part of the wheel picture, so it also helps to compare the wheel's width with the tire you are considering. Several 245/45R17 products in this fitment range are intended for wheels around the mid-7-inch to 9-inch width range, and checking the actual wheel on the car helps avoid choosing a tire that is correct in diameter but mismatched to the wheel setup.
Does the 2004 Pontiac GTO Base use the same tire size?
Yes. The 2004 Pontiac GTO Base uses the same 245/45R17 radial tire size as the covered model fitment. There is no separate primary size to sort through for that sub-model.
That consistency means most buyers can move quickly from fitment confirmation into comparing tire style and intended use. It is still worth checking the actual wheels on the car if it has been modified, because aftermarket wheel width, offset, or suspension changes can affect how a 245/45R17 tire sits and clears even when the basic size remains correct.
Choosing the Right Tire
What should I consider when choosing a 245/45R17 tire for a 2004 Pontiac GTO?
Start with the correct 245/45R17 size and confirm that the tire matches a 17-inch wheel with suitable width. From there, the main differences are tire purpose, sidewall appearance, brand, and series, since this fitment includes both general road-going radials and a drag-race-oriented radial option.
A street-driven GTO may call for a different choice than one built around straight-line traction or a specific visual style. Comparing rim-width guidance, sidewall treatment, and the tire's intended character helps narrow the field, especially when the car's role is split between weekend cruising, show presentation, and more aggressive performance use.
What sidewall styles are available for 2004 Pontiac GTO tires?
The available 245/45R17 tire options for the 2004 Pontiac GTO include blackwall, raised white letter, and redline sidewall styles. Those choices give the car a distinctly different presentation even when the underlying size stays the same.
Blackwall usually keeps the look understated and modern, while raised white letter and redline treatments add more visual character. The right choice depends on whether the car is being kept closer to a clean contemporary appearance or given a stronger performance-inspired style, so appearance should be considered alongside wheel compatibility and the tire's intended use.
What brands offer tires for the 2004 Pontiac GTO?
The 2004 Pontiac GTO's 245/45R17 fitment is available from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster. Those brands cover several radial series and include both standard blackwall offerings and more style-driven sidewall choices.
Brand alone is not the whole decision, because each option also carries its own tire series and intended character. A better comparison looks at the exact size, wheel-width compatibility, sidewall treatment, and whether the tire is aimed at general street use or a specialty role, so the selection matches how the GTO will actually be driven and presented.
Restoration & Appearance
Which tire should I choose for a period-style 2004 Pontiac GTO?
A period-style 2004 Pontiac GTO tire choice usually starts with the correct 245/45R17 size, then narrows by sidewall presentation and overall tire character. In this fitment, blackwall keeps a cleaner modern look, while raised white letter or redline options can give the car a more assertive enthusiast-oriented appearance.
Because 2004 sits in a modern muscle revival context rather than a vintage bias-ply era, appearance often matters as much as strict restoration language. Buyers chasing a very specific showroom-era look should compare the car's original delivery photos, brochures, window sticker details, or marque-specific references before treating any current sidewall style as the only correct visual answer.
How does tire construction affect the appearance of a restored 2004 Pontiac GTO?
On a 2004 Pontiac GTO, construction does not create a bias-ply-versus-radial visual decision because the primary fitment is already radial. The visible appearance difference comes more from sidewall style, brand presentation, and the tire series you choose within the 245/45R17 size.
That means a restoration-minded owner can stay within the correct radial format while still shaping the car's overall look. A blackwall tire tends to feel cleaner and less conspicuous, while raised white letter or redline versions draw more attention to the wheel opening, so the final choice should suit the car's finish level, wheel style, and intended presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Pontiac GTO?
Yes. A 2004 Pontiac GTO may still use the correct 245/45R17 tire size, but aftermarket wheels, altered wheel offset, suspension changes, or ride-height adjustments can change how that tire fits on the car. Clearance at the fender, suspension, and steering range can all be affected.
That is why a modified GTO should be measured as it sits rather than treated like a stock-wheel car. Confirming wheel diameter and width is the first step, then checking clearance through full steering travel and normal suspension movement helps prevent rubbing or an awkward stance even when the tire itself is the proper size.
What should I inspect before driving a 2004 Pontiac GTO on new tires?
Before putting a 2004 Pontiac GTO back on the road, inspect the wheels for damage, verify correct inflation, and make sure the tires are mounted in the proper 245/45R17 fitment. It also helps to look over valve stems, tread and sidewalls, and the general condition of the suspension and alignment-related wear surfaces.
A short initial drive followed by a recheck can reveal issues that are easy to miss in the garage, such as vibration, rubbing, or uneven seating. Keeping an eye on air pressure and watching for early signs of irregular wear is especially useful on performance-oriented cars, where wheel setup and suspension condition can strongly influence how a new tire behaves.
How often should tires on a 2004 Pontiac GTO be inspected?
Tires on a 2004 Pontiac GTO should be inspected regularly, not just by mileage. Collector-driven or weekend-use cars often spend long periods parked, so pressure loss, flat spotting, sidewall aging, and general condition can matter as much as tread depth.
A visual check before each drive and a more careful inspection at routine service intervals is a practical habit for a car like this. Attention should go to air pressure, cuts, bulges, cracking, uneven wear, and anything that suggests alignment or suspension issues, because low-use performance cars can age their tires in place even when they do not wear them out quickly.
