The 2008 Chevrolet Impala sits in the later front-wheel-drive chapter of Chevrolet’s long-running full-size sedan line, balancing everyday practicality with a familiar American nameplate that still appealed to commuters, fleet buyers, and performance-minded drivers alike. Tire fitment on this model depends on the exact trim, with 225/60R16, 225/55R17, and 235/50R18 radial sizes all used across the range. That means the key decision is not just brand, but also confirming the correct wheel diameter and sub-model before choosing among blackwall, redline, whitewall, raised-yellow-letter, or raised white letter styles. For a stock or restored appearance, the right tire choice starts with matching the Impala’s exact configuration.
Which Tire Size Is Right for The 2008 Chevrolet Impala
The 2008 Chevrolet Impala uses three different primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. All three are radial fitments, but they are tied to 16-inch, 17-inch, or 18-inch wheels, so the first step is confirming the trim and the wheels actually on the car before comparing tire style, brand, or sidewall treatment.
In 235/50R18, the 235 is the nominal section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter in inches. This size is used on certain upper-trim or special Impala configurations and gives the buyer an 18-inch wheel fitment to match. Available choices include blackwall performance-oriented lines from BFGoodrich and Nitto, along with Pro-Trac Street Pro III options in redline and RWL form. It is the right size to evaluate when the car already carries the correct 18-inch wheel setup.
In 225/60R16, the 225 is the nominal section width in millimeters, 60 is the aspect ratio, R means radial construction, and 16 identifies the wheel diameter. This size appears on several 2008 Impala sub-models, making it an important fitment for buyers with stock 16-inch wheels. Product choices range from black-free performance is not the theme here; instead, the available selection includes raised-yellow-letter, redline, pin-white-stripe, wide whitewall, and narrow whitewall styles from Goodyear, BFGoodrich, and Travelstar. It is a useful size for owners balancing standard fitment with a more custom or restoration-inspired look.
In 225/55R17, the 225 indicates section width in millimeters, the 55 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On the 2008 Impala, this size serves specific sub-models that use a 17-inch wheel rather than the 16-inch or 18-inch alternatives. Available tires include blackwall g-Force series options from BFGoodrich as well as Silvertown Radial versions in wide whitewall and redline form. It is the size to compare when the car’s trim and wheel package call for a 17-inch radial but appearance still matters.
Sub-model fitment on the 2008 Chevrolet Impala is not the same across the lineup, and tire size changes with trim and wheel package. Checking the exact sub-model matters because this Impala uses three different radial sizes on three different rim diameters.

2008 Chevrolet Impala 50th Anniversary Edition
The 2008 Chevrolet Impala 50th Anniversary Edition uses the 235/50R18 radial size, placing it with the 18-inch-wheel Impala configurations. Tire selection here centers on confirming the 18-inch setup and then choosing between blackwall performance-style options or appearance-driven redline and RWL alternatives.
The 2008 Chevrolet Impala LS uses the 225/60R16 radial size on a 16-inch wheel. That gives the buyer a broad mix of traditional and custom-leaning sidewall choices, so the main decision becomes whether the car is staying stock in appearance or moving toward a more distinctive presentation.
The 2008 Chevrolet Impala LT w/3.5L Eng. also uses the 225/60R16 radial size. Since this trim shares the same basic fitment as other 16-inch Impalas, the practical next step is choosing a tire style that matches the car’s intended use and appearance rather than searching across multiple primary sizes.
The 2008 Chevrolet Impala LT w/3.9L Eng. uses the 225/55R17 radial size, making wheel diameter confirmation especially important if the car has changed hands or been modified. Once the 17-inch setup is verified, the decision shifts to blackwall performance-style tires versus redline or wide whitewall styling.
The 2008 Chevrolet Impala LTZ uses the 235/50R18 radial size. Buyers selecting tires for this trim should focus first on the correct 18-inch wheel fitment, then compare the available series and sidewall treatments according to whether the goal is modern road use or a more distinctive period-inspired look.
The 2008 Chevrolet Impala Police uses the 225/60R16 radial size. That keeps the fitment straightforward, but it is still worth confirming the actual wheel setup because former fleet vehicles are often changed over time and tire selection should match the current wheels and intended service.
The 2008 Chevrolet Impala SS uses the 235/50R18 radial size, sharing its fitment with other 18-inch Impala variants. That makes the main choice less about finding the correct primary size and more about comparing available tire series, sidewall style, and rim-width compatibility within 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.

Tire questions for a 2008 Chevrolet Impala usually come down to trim-specific sizing, wheel diameter, sidewall style, and choosing among available radial options. The answers below focus on exact fitment, appearance, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2008 Chevrolet Impala?
A 2008 Chevrolet Impala uses one of three radial tire sizes: 225/60R16, 225/55R17, or 235/50R18. The correct size depends on the exact sub-model, with LS, LT w/3.5L Eng., and Police using 225/60R16, LT w/3.9L Eng. using 225/55R17, and 50th Anniversary Edition, LTZ, and SS using 235/50R18.
The practical next step is confirming the car’s trim and wheel diameter before choosing a tire. Many Impalas have changed wheels over time, so the size on the car now matters just as much as the original trim assignment when selecting the right replacement.
What size rim does a 2008 Chevrolet Impala use?
A 2008 Chevrolet Impala uses 16-inch, 17-inch, or 18-inch rims depending on the sub-model and tire size. The 225/60R16 fitment uses a 16-inch rim, 225/55R17 uses a 17-inch rim, and 235/50R18 uses an 18-inch rim.
Wheel diameter should be verified before anything else because each primary tire size is tied to a different rim size. A tire for one of these wheel diameters should not be treated as a substitute for another without confirming the actual wheels installed on the car.
Do all 2008 Chevrolet Impala sub-models use the same tire size?
No, 2008 Chevrolet Impala sub-models do not all use the same tire size. The lineup is split across three radial sizes, with 225/60R16, 225/55R17, and 235/50R18 each assigned to different versions of the car.
That matters because tire shopping for this Impala starts with the exact sub-model or the actual wheel package on the vehicle. A buyer looking at an LS, Police, LT, LTZ, SS, or 50th Anniversary Edition should confirm which wheel diameter the car carries before comparing brands or sidewall styles.
Choosing the Right Tire
What should I consider when choosing a tire for a 2008 Chevrolet Impala?
Start with the correct primary size for the specific 2008 Chevrolet Impala trim: 225/60R16, 225/55R17, or 235/50R18. After size and wheel diameter are confirmed, compare construction details such as rim-width suitability, sidewall style, load figures where stated, and the overall character of the tire series.
The right choice depends on how the car is used and how it should look. A stock daily-driver appearance, a more performance-oriented blackwall presentation, or a custom-style whitewall or redline look can all point the buyer toward different products within the correct size.
What sidewall styles are available for 2008 Chevrolet Impala tires?
Sidewall choices for the 2008 Chevrolet Impala include Blackwall, Redline, RWL, Raised-Yellow-Letter, Pin-White-Stripe, Wide Whitewall, and Narrow Whitewall, depending on tire size. Not every style appears in every size, so the exact trim and wheel package still determine which appearance options are realistic.
That gives this Impala a wider appearance range than many late-model sedans. Buyers who want a clean modern look may stay with blackwall, while those after a more custom or nostalgic presentation can compare the available stripe and whitewall treatments within the correct tire size.
What brands offer tires for the 2008 Chevrolet Impala?
Tires for the 2008 Chevrolet Impala are available from BFGoodrich, Nitto, Goodyear, Pro-Trac, and Travelstar across the three applicable radial sizes. Brand availability changes by size, so some trims have a more performance-leaning blackwall selection while others also include whitewall, redline, or lettered sidewall choices.
The most useful comparison is not brand name alone but how each brand’s available series fits the car’s intended use and visual style. Once the size is confirmed, compare the sidewall treatment, rim-width specification, and any stated load figures that matter for the vehicle’s setup.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Chevrolet Impala?
A period-style 2008 Chevrolet Impala tire choice depends first on using the correct trim-specific size, then selecting a sidewall treatment that suits the look you want. Whitewall, pin-white-stripe, redline, raised-yellow-letter, and RWL options are all available within certain Impala sizes, giving the car anything from restrained to more custom visual character.
Appearance alone should not override basic fitment. Matching the tire to the car’s actual 16-inch, 17-inch, or 18-inch wheel setup is the foundation, and buyers pursuing exact originality should still compare details with model-specific photos, sales literature, or marque references before making a final choice.
How does tire construction affect the appearance of a restored 2008 Chevrolet Impala?
On the 2008 Chevrolet Impala, the primary fitments are radial tires, so construction change is not the main appearance decision. The bigger visual differences come from sidewall treatment and tire series, especially when comparing blackwall designs with redline, whitewall, pinstripe, or lettered alternatives.
That means a restored or carefully presented Impala can look notably different even while staying within the correct size and radial construction. Choosing the right sidewall style has more influence on the car’s finished look than changing construction, provided the tire still matches the proper wheel diameter and trim-specific fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Chevrolet Impala?
Yes, modifications can affect tire fitment on a 2008 Chevrolet Impala. Aftermarket wheels, suspension changes, lowering, brake upgrades, or previous fleet-service changes can alter the wheel diameter, wheel width, or available clearance even when the car began with one of the stock 16-inch, 17-inch, or 18-inch fitments.
That is why the car should be checked as it sits, not just by trim name. Measure the actual wheel diameter, confirm wheel width, and inspect clearance at the fender, strut, and steering range before choosing a replacement tire, especially if the car no longer appears to be in stock configuration.
What should I inspect before driving a 2008 Chevrolet Impala on new tires?
Before driving a 2008 Chevrolet Impala on new tires, inspect basic installation and vehicle condition. Confirm the tire size matches the wheel diameter, check inflation pressure, look over the valve stems, and make sure there is no rubbing at full steering lock or under normal suspension movement.
A longer look at the car is worthwhile too. Worn suspension parts, alignment problems, damaged wheels, or uneven brake condition can shorten tire life and affect road behavior, so it helps to catch those issues early rather than assuming every problem is solved by installing new tires.
How often should tires on a 2008 Chevrolet Impala be inspected?
Tires on a 2008 Chevrolet Impala should be inspected regularly, especially before longer drives and any time the car has been parked for an extended period. Look for uneven wear, sidewall cracking, punctures, bulges, and gradual air loss, and pay attention to any change in vibration or steering feel.
Routine inspection matters even more on low-use cars because age and storage conditions can affect a tire long before the tread appears worn out. Pressure checks, visual condition checks, and occasional tread-depth review help keep the correct Impala tire size performing as intended on the road.
