The 2006 Chevrolet Trucks SSR blended retro pickup styling with contemporary GM performance hardware, making it one of the more distinctive specialty trucks of its era. Buyers today usually approach an SSR with equal attention to appearance, stance, and real road manners, so tire fitment matters at both ends of the truck. The 2006 Chevrolet Trucks SSR uses a staggered radial setup, with 255/45R19 up front and 295/40R20 at the rear. That means the tire decision is less about choosing between primary sizes and more about matching the correct front and rear fitment, wheel diameters, and overall presentation. Careful confirmation is especially important before any wheel, suspension, or replacement-size change.
Which Tire Size Is Right for The 2006 Chevrolet Trucks SSR
The 2006 Chevrolet Trucks SSR uses two primary tire sizes, and they are tied to position rather than interchangeable across the truck. A 255/45R19 radial is used at the front and a 295/40R20 radial is used at the rear, so the first step is confirming which end of the vehicle you are fitting and verifying the wheel diameter before selecting a tire.
255/45R19 is a metric radial size in which 255 identifies nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter in inches. On the 2006 Chevrolet Trucks SSR, this size serves the front position and is part of the truck's staggered setup. Its role is not the same as the rear tire, so it should be evaluated as a front-specific fitment rather than a universal SSR size. When replacing it, confirm the front wheel size and make sure any existing wheel or suspension changes have not altered clearance or intended fitment.
295/40R20 is a metric radial size with a 295-millimeter nominal section width, a 40-series profile, radial construction, and a 20-inch rim diameter. On the 2006 Chevrolet Trucks SSR, this size is used at the rear and gives the truck its wider back-tire fitment. Available choices in this size include a Blackwall Nitto NT555 G2 radial, so buyers can compare product character as well as size. The practical priority is keeping the rear-specific size matched to the correct wheel and checking that any aftermarket wheel or ride-height change has not affected clearance.
Tire fitment on the 2006 Chevrolet Trucks SSR is straightforward once position is confirmed, because the covered front and rear sub-model entries each use their own dedicated size. Checking the exact front or rear application matters because this truck uses different radial sizes and different rim diameters at each end.

2006 Chevrolet Trucks SSR Base Front
The 2006 Chevrolet Trucks SSR Base Front uses a 255/45R19 radial tire as the front half of the truck's staggered fitment. That makes front-wheel diameter and front-end clearance the key checks when selecting a replacement or confirming an existing wheel and tire setup.
The 2006 Chevrolet Trucks SSR Base Rear uses a 295/40R20 radial tire, giving the rear axle its wider and larger-diameter wheel fitment. Tire selection here should stay focused on the rear-specific size, wheel compatibility, and clearance around the suspension and body if the truck has been modified.
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 2006 Chevrolet Trucks SSR?
The 2006 Chevrolet Trucks SSR uses a staggered tire setup with two different radial sizes. The front uses 255/45R19, while the rear uses 295/40R20. Those sizes are tied to position, so the truck does not use the same tire size at all four corners.
That means the first fitment step is identifying whether the tire is for the front or rear axle and then confirming the wheel diameter already on the truck. If the SSR has aftermarket wheels, suspension changes, or a non-original stance, it is wise to verify clearance and wheel compatibility before choosing a replacement tire.
What size rim does a 2006 Chevrolet Trucks SSR use?
The 2006 Chevrolet Trucks SSR uses two rim diameters as part of its staggered setup. The front tire size, 255/45R19, is matched to a 19-inch rim, and the rear tire size, 295/40R20, is matched to a 20-inch rim.
Rim confirmation matters because the front and rear tire sizes are built around different wheel diameters and should not be treated as interchangeable. A quick check of the actual wheel on the truck is especially helpful when the SSR has custom wheels, since the correct tire choice depends on matching the right size to the right axle.
Why does the 2006 Chevrolet Trucks SSR have more than one tire size?
The 2006 Chevrolet Trucks SSR has more than one tire size because it uses a staggered front-and-rear fitment. The front is fitted with 255/45R19 tires, while the rear uses wider 295/40R20 tires. This is a position-specific setup rather than a case of alternate fitments for the same wheel.
For the buyer, that changes the decision process. Instead of choosing between multiple primary sizes for one location, the goal is to preserve the correct size at each end of the truck unless a carefully planned wheel-and-tire change is being made. Any departure from the stock-style layout should be checked for wheel diameter, clearance, and overall compatibility.
Choosing the Right Tire
What should I consider when choosing SSR tires for a 2006 Chevrolet Trucks SSR?
Start with the truck's staggered fitment, because the 2006 Chevrolet Trucks SSR uses 255/45R19 at the front and 295/40R20 at the rear. The right tire choice begins with selecting the correct axle position, matching the wheel diameter, and staying with radial construction in the proper size.
From there, compare the tire's overall character, sidewall presentation, and any published product details that matter to how the truck is used. A street-driven SSR may be chosen differently than one focused mainly on appearance, but either way the wheel setup, tire dimensions, and clearance should be reviewed before making a change.
What sidewall styles are available for 2006 Chevrolet Trucks SSR tires?
A Blackwall sidewall style is available in the SSR's rear 295/40R20 fitment. That presentation suits the truck's modern performance-oriented sizing and gives a clean, understated look without adding period-style stripe or whitewall treatment.
Sidewall style should still be considered as part of the truck's overall appearance, especially on a specialty vehicle like the SSR where stance and wheel design are a big part of its visual impact. The practical step is to choose the correct front or rear size first, then decide whether the available sidewall treatment matches the look you want.
What brands offer tires for the 2006 Chevrolet Trucks SSR?
Nitto is available in the 2006 Chevrolet Trucks SSR's rear 295/40R20 fitment through the NT555 G2 series. That gives buyers a named product option in the wider rear size, with a Blackwall radial construction that aligns with the SSR's modern staggered setup.
Brand choice should be considered alongside the correct size, wheel diameter, and intended use rather than by name alone. Since the SSR uses different front and rear sizes, it is important to verify the exact axle position being replaced and make sure any modified wheel package still supports the tire being considered.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Chevrolet Trucks SSR?
A period-style approach for a 2006 Chevrolet Trucks SSR starts by preserving its staggered radial layout, with 255/45R19 at the front and 295/40R20 at the rear. Keeping the correct front-and-rear relationship matters more than chasing a single visual theme, because the SSR's appearance depends heavily on its wheel and tire proportions.
From there, look at sidewall presentation and overall stance rather than assuming one tire is automatically the right restoration answer. Since the SSR is a modern specialty truck with a distinctive factory-era look, accurate originality questions are best settled with marque-specific references if an exact as-delivered presentation is important.
Does correct tire fitment matter for a 2006 Chevrolet Trucks SSR restoration?
Correct tire fitment matters on a 2006 Chevrolet Trucks SSR because the truck's stance, front-to-rear proportion, and overall visual balance depend on its staggered setup. Using 255/45R19 at the front and 295/40R20 at the rear preserves the size relationship that defines how the SSR sits.
Fitment also affects more than appearance. Incorrect wheel diameter or a mismatched tire at one end can create problems with clearance and change the truck's presentation in ways that feel out of character. A restoration-minded owner should confirm the actual wheels on the truck before replacing tires, especially if previous owners made modifications.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Chevrolet Trucks SSR?
Yes, modifications can affect tire fitment on a 2006 Chevrolet Trucks SSR. The truck already uses different front and rear tire sizes and different wheel diameters, so aftermarket wheels, lowering, suspension changes, or body alterations can change how a 255/45R19 front or 295/40R20 rear tire sits in the wheel opening.
That makes a physical check important before replacing tires on a modified SSR. Wheel width, offset, steering travel, and rear clearance all deserve attention, especially if the truck no longer wears its original-style wheel package. Measuring the existing setup is often more useful than assuming a stock-size tire will behave the same on changed hardware.
What should I inspect before driving a 2006 Chevrolet Trucks SSR on new tires?
Before driving a 2006 Chevrolet Trucks SSR on new tires, inspect basic installation and condition items first. Confirm that the front 255/45R19 and rear 295/40R20 tires are mounted in the correct positions, then check inflation, valve stems, lug torque, visible bead seating, and any signs of rubbing at full steering lock or suspension movement.
A short, careful road test is a smart next step. Pay attention to vibration, pull, unusual noise, or contact with inner liners and suspension parts. Since the SSR uses a staggered layout, front and rear clearances should both be checked separately, particularly when wheel changes or previous suspension work may have altered normal fitment.
How often should tires on a 2006 Chevrolet Trucks SSR be inspected?
Tires on a 2006 Chevrolet Trucks SSR should be inspected regularly, especially because many specialty vehicles see uneven use patterns. Frequent visual checks for cracking, cuts, bulges, tread wear, and air loss help catch age- or storage-related issues before they become road-use problems.
A collector-driven truck benefits from inspection before longer trips and after long periods parked, not just at service intervals. The SSR's different front and rear sizes also mean each axle should be checked on its own. Good pressure habits, clean storage conditions, and early attention to wear or aging all support safer, more predictable road use.
