The 2004 Chevrolet Trucks SSR blended retro pickup styling with modern GM performance-era hardware, making it one of the more distinctive specialty trucks of the early 2000s. Its retractable hardtop and staggered wheel-and-tire setup give it a very different fitment story than a conventional pickup. The 2004 Chevrolet Trucks SSR uses radial tires in two sizes, with 255/45R19 at the front and 295/40R20 at the rear. That means the key decision is not choosing one universal size, but confirming front-versus-rear placement and matching the tire to the truck’s wheel diameter and intended use. Owners should also verify that the vehicle still carries its original staggered wheel setup before replacing tires.
Which Tire Size Is Right for The 2004 Chevrolet Trucks SSR
The 2004 Chevrolet Trucks SSR uses two primary tire sizes, and they are position-specific rather than interchangeable. A 255/45R19 radial belongs on the front and a 295/40R20 radial belongs on the rear, so the first step is confirming both wheel position and rim diameter before selecting a replacement tire.
255/45R19 is a modern metric radial size in which 255 identifies the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2004 Chevrolet Trucks SSR, this is the front tire size and it works as part of the truck’s staggered setup. Its role is tied to correct front-end fitment rather than universal use across all four corners. When replacing it, the important step is preserving the intended front sizing and confirming the truck still wears the proper 19-inch front wheel.
295/40R20 is a modern metric radial size with a 295-millimeter nominal section width, a 40-series profile, radial construction, and a 20-inch rim diameter. On the 2004 Chevrolet Trucks SSR, this size is used at the rear and is part of the vehicle’s wider rear-tire layout. Available product choice in this size includes a Blackwall Nitto NT555 G2, giving the rear fitment a distinctly modern performance-oriented presentation. Choosing this size starts with confirming the rear wheel remains a 20-inch setup and that the truck has not been altered from its original front-to-rear tire arrangement.
Fitment on the 2004 Chevrolet Trucks SSR is straightforward once wheel position is identified, because the covered sub-models separate the truck into front and rear tire applications. Checking the exact position matters since the SSR uses different sizes and different rim diameters at each end.

2004 Chevrolet Trucks SSR Base Front
The 2004 Chevrolet Trucks SSR Base Front uses a 255/45R19 radial tire on the front axle. Tire selection here centers on preserving the correct front size and confirming that the truck still has its proper 19-inch front wheels before replacement.
The 2004 Chevrolet Trucks SSR Base Rear uses a 295/40R20 radial tire on the rear axle. That makes rear tire selection more about matching the wider 20-inch rear setup and choosing a tire that suits the truck’s appearance and road-use goals.
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 Chevrolet Trucks SSR?
The 2004 Chevrolet Trucks SSR uses two tire sizes rather than one universal fitment. It carries 255/45R19 radial tires at the front and 295/40R20 radial tires at the rear, which creates a staggered setup with different widths, profiles, and rim diameters at each end of the truck.
That means replacement starts with identifying wheel position before choosing a tire. A front tire should not be selected by rear size, and a rear tire should not be selected by front size. It is also smart to confirm that the truck still has its original 19-inch front and 20-inch rear wheels, especially if previous owners changed wheels or suspension components.
What size rim does a 2004 Chevrolet Trucks SSR use?
The 2004 Chevrolet Trucks SSR uses two rim diameters as part of its factory-style tire layout. The front tire size, 255/45R19, mounts on a 19-inch rim, while the rear tire size, 295/40R20, mounts on a 20-inch rim.
Because the SSR uses different rim diameters front and rear, wheel confirmation is one of the most important fitment checks before buying tires. Looking only at the vehicle name is not enough if the truck has been modified. Verifying the actual wheel size at each corner helps prevent ordering a front tire for a rear wheel, or a rear tire for a front wheel.
Why does the 2004 Chevrolet Trucks SSR have more than one tire size?
The 2004 Chevrolet Trucks SSR uses more than one tire size because it has a staggered tire setup. The front uses 255/45R19 and the rear uses 295/40R20, giving the truck a narrower front fitment and a wider rear fitment with different rim diameters.
For the buyer, that changes the selection process completely. Instead of choosing one size for all four corners, the SSR owner needs to match each tire to its correct axle position. It also makes visual and mechanical checks more important, since aftermarket wheels, mixed tire replacements, or earlier suspension changes can leave the truck wearing a different setup than expected.
Choosing the Right Tire
What should I consider when choosing tires for a 2004 Chevrolet Trucks SSR?
Start with the SSR’s staggered fitment, since this truck uses 255/45R19 in front and 295/40R20 in the rear. The correct tire choice begins with matching the right size to the right axle, then confirming radial construction, wheel diameter, and the type of driving the truck is expected to see.
After size and position are settled, compare practical differences such as sidewall style, tire series, and product specifications that matter to your use. A truck kept close to stock may call for a different visual approach than one with a more modern street-driven focus. Wheel setup, suspension height, and overall appearance goals should all be reviewed before making a final choice.
What sidewall styles are available for 2004 Chevrolet Trucks SSR tires?
The available product assortment for the 2004 Chevrolet Trucks SSR currently includes a Blackwall tire in the 295/40R20 rear size. Blackwall is a modern, understated sidewall treatment that suits the SSR’s performance-oriented rear fitment without adding a white stripe or raised-letter presentation.
Sidewall style matters because it changes the truck’s overall look even when the size stays correct. Some owners want a cleaner, more contemporary presentation, while others focus first on preserving the SSR’s original visual balance. Sidewall appearance should be chosen only after confirming the proper front or rear size, since style never overrides correct fitment.
What brands offer tires for the 2004 Chevrolet Trucks SSR?
Current product coverage for the 2004 Chevrolet Trucks SSR includes Nitto in the 295/40R20 rear size. That rear-size offering appears in the Nitto NT555 G2 series, giving SSR owners a recognizable modern radial choice for the wider rear wheel position.
Brand comparison only becomes useful after the correct axle position and tire size are confirmed. Since the SSR uses different front and rear fitments, a brand option in one size does not automatically represent the full vehicle setup. It is best to treat brand as one part of the decision alongside size, wheel compatibility, sidewall appearance, and how the truck is actually driven.
Restoration & Appearance
Which tire should I choose for a period-style 2004 Chevrolet Trucks SSR?
A period-style 2004 Chevrolet Trucks SSR should begin with the proper staggered radial sizes: 255/45R19 in front and 295/40R20 in the rear. Keeping the truck’s original front-to-rear sizing relationship preserves the stance and visual balance that are central to the SSR’s early-2000s specialty-truck character.
From there, the choice becomes more about presentation and use than about changing size. A Blackwall rear tire gives a clean modern look, but exact originality questions are better settled through factory literature, original-window-sticker documentation, or marque-specific references. Tire appearance should support the truck’s restoration goals without compromising the correct wheel-position fitment.
Does correct tire fitment matter for a 2004 Chevrolet Trucks SSR restoration?
Correct tire fitment matters on a 2004 Chevrolet Trucks SSR restoration because the truck does not use one same-size arrangement at all four corners. Its 255/45R19 front and 295/40R20 rear layout is part of the SSR’s intended visual stance and helps define how the restored truck presents overall.
Using the wrong diameter or reversing front and rear sizing can change the truck’s proportions even before it affects clearance or handling. Restoration-minded owners should confirm actual wheel diameters, inspect for prior modifications, and compare the truck’s current setup against known vehicle-specific references. Getting fitment right is one of the easiest ways to avoid a finished truck that looks subtly off.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Chevrolet Trucks SSR?
Yes, modifications can affect tire fitment on a 2004 Chevrolet Trucks SSR, especially because the truck already uses a staggered front-and-rear setup. Changes such as aftermarket wheels, altered offsets, lowering, suspension work, or body modifications can all affect how a 255/45R19 front tire or 295/40R20 rear tire sits in the wheel opening.
Even when the size code matches, the actual wheel and vehicle setup may no longer match stock dimensions. Checking wheel diameter, wheel width, tire-to-fender clearance, and steering clearance is important before replacement. That extra step is particularly worthwhile on SSRs, since custom wheels and stance changes are common enough to make visual confirmation smarter than assumption.
What should I inspect before driving a 2004 Chevrolet Trucks SSR on new tires?
Before driving a 2004 Chevrolet Trucks SSR on new tires, inspect basic installation and condition items at all four corners. Tire pressure, wheel fastener torque, bead seating, valve condition, visible sidewall damage, and tread condition should all be checked, along with confirming that the front tires and rear tires are mounted in their proper positions.
A short test drive should also be used to watch for rubbing, vibration, or steering issues. Since the SSR uses 19-inch front wheels and 20-inch rear wheels, it is worth rechecking wheel position if the truck has been serviced, stored, or modified. Collector-oriented vehicles can sit for long periods, so fresh tires should never replace a full roadworthiness inspection.
How often should tires on a 2004 Chevrolet Trucks SSR be inspected?
Tires on a 2004 Chevrolet Trucks SSR should be inspected regularly, especially if the truck is driven seasonally or stored for long stretches. Even low-mileage tires deserve routine checks for air loss, cracking, bulges, cuts, uneven wear, and any sign that the front and rear tires are no longer matched to their proper wheel positions.
A quick inspection before each drive is a sensible habit for a specialty vehicle like the SSR, with a more thorough review at regular service intervals and before longer trips. Storage conditions matter too, since prolonged heat, sunlight, and ozone exposure can age tires even when tread looks good. Tire condition and age are just as important as remaining tread depth.
