The 2006 Buick LaCrosse marked Buick’s move toward a more contemporary midsize sedan, blending traditional Buick comfort with cleaner styling and a broader appeal than the Century and Regal models it followed. That matters when choosing tires, because this car uses two distinct modern radial sizes depending on trim: 225/60R16 or 225/55R17. The key decision is confirming whether the car is a CX or CXL on 16-inch wheels or a CXS on 17-inch wheels, then deciding among blackwall, redline, whitewall, or raised-letter presentations where available. For owners preserving a stock look or tailoring the car’s character, the right tire choice starts with exact trim and wheel verification.
Which Tire Size Is Right for The 2006 Buick LaCrosse
The 2006 Buick LaCrosse uses two primary tire sizes, and the correct one depends on sub-model and wheel diameter. CX and CXL models use 225/60R16 on a 16-inch rim, while the CXS uses 225/55R17 on a 17-inch rim. Before comparing brands, sidewall styles, or tire series, the first step is confirming the exact trim level and making sure the car still has the wheel size it was set up for.
A 225/60R16 tire is a metric radial size with a 225-millimeter section width, a 60-series aspect ratio, and fitment for a 16-inch rim. On the 2006 Buick LaCrosse, this size is used on the CX and CXL and keeps the car in a clearly modern radial fitment rather than a vintage bias-ply format. Available choices include Goodyear, BFGoodrich, and Travelstar, with sidewall treatments such as raised yellow letter, redline, pin-white-stripe, wide whitewall, and narrow whitewall. This size is the right starting point for buyers balancing everyday road use with a more traditional or custom appearance.
A 225/55R17 tire uses the same 225-millimeter nominal width as the 16-inch option, but with a lower 55-series profile and fitment for a 17-inch rim. On the 2006 Buick LaCrosse, this size belongs to the CXS, so it should be selected only after confirming that trim and wheel diameter. Product choices include BFGoodrich performance-oriented g-Force series tires in blackwall form as well as Silvertown Radial options with wide whitewall or redline styling. This size suits buyers who want to keep the CXS wheel setup intact while choosing between sportier and more restoration-inspired tire presentation.
Sub-model fitment matters on the 2006 Buick LaCrosse because tire size changes with trim. CX and CXL share one setup, while the CXS moves to a different size on a different rim diameter, so identifying the exact version is the first step before comparing tire options.

2006 Buick LaCrosse CX
The 2006 Buick LaCrosse CX uses the 225/60R16 radial size on a 16-inch wheel setup. That makes tire selection more about choosing the right sidewall style, brand, and overall look than sorting through multiple fitment sizes.
The 2006 Buick LaCrosse CXL also uses the 225/60R16 radial size, matching the CX in basic tire fitment. Buyers can focus on whether they want a more understated black-free traditional look such as whitewall or pin stripe styling, while still staying within the correct size.
The 2006 Buick LaCrosse CXS uses 225/55R17, making it the trim that steps up to a 17-inch wheel diameter. Tire choice here starts with keeping that wheel size confirmed, then deciding between blackwall performance-oriented tires and more classic-looking redline or whitewall radial options.
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)

Common 2006 Buick LaCrosse tire questions usually come down to trim-specific size, 16-inch versus 17-inch wheel fitment, sidewall style, and how to choose between touring-style and performance-oriented radial options.
Tire Size & Fitment
What tire size fits a 2006 Buick LaCrosse?
The 2006 Buick LaCrosse uses two tire sizes: 225/60R16 and 225/55R17. CX and CXL models use 225/60R16, while the CXS uses 225/55R17. Both are modern radial sizes, but they are tied to different wheel diameters and should not be treated as the same fitment choice.
The practical step is to confirm the trim level and check the actual wheels on the car before selecting tires. A used LaCrosse may have had wheel changes over time, so matching the tire size to the installed rim diameter matters just as much as matching it to the badge on the trunk.
What size rim does a 2006 Buick LaCrosse use?
A 2006 Buick LaCrosse uses either a 16-inch or 17-inch rim, depending on sub-model. The CX and CXL use the 225/60R16 size on a 16-inch rim, and the CXS uses the 225/55R17 size on a 17-inch rim. That rim diameter difference is central to choosing the correct tire.
Checking the installed wheel size is especially important if the car has replacement wheels or has changed hands several times. The tire size molded on the current sidewall and the wheel diameter itself should both agree, since moving between 16-inch and 17-inch tires requires the corresponding rim.
Do all 2006 Buick LaCrosse sub-models use the same tire size?
No, the 2006 Buick LaCrosse does not use one tire size across every sub-model. The CX and CXL share 225/60R16, but the CXS uses 225/55R17. Both are radial tire sizes, yet they belong to different wheel packages and should be selected by trim rather than by model name alone.
That difference affects more than the sidewall marking. It changes the required rim diameter and influences which product styles are available, from traditional whitewall or redline presentations to blackwall performance-oriented choices. Verifying the exact sub-model keeps the tire search focused on the right size from the start.
Choosing the Right Tire
What should I consider when choosing a 2006 Buick LaCrosse tire?
Start with the correct size for the exact LaCrosse sub-model: 225/60R16 for CX and CXL or 225/55R17 for CXS. From there, compare the tire’s construction, rim-width compatibility, sidewall style, and the kind of look you want, since this vehicle has options ranging from traditional whitewall and redline radials to blackwall and raised-letter designs.
The best comparison is not just brand versus brand, but how the tire suits the car’s setup and purpose. A LaCrosse kept close to stock may call for a more conservative visual style, while a CXS owner may lean toward a sportier series. Wheel size, appearance, and intended road use should all stay aligned.
What sidewall styles are available for 2006 Buick LaCrosse tires?
The 2006 Buick LaCrosse has a wide spread of sidewall styles depending on tire size, including raised-yellow-letter, redline, pin-white-stripe, wide whitewall, narrow whitewall, and blackwall. The 225/60R16 size offers the broadest traditional-style variety, while 225/55R17 includes blackwall, redline, and wide whitewall choices.
Sidewall style changes the car’s presentation more than many buyers expect. A whitewall or pin stripe can reinforce Buick’s traditional character, while blackwall or raised lettering gives the car a more contemporary or assertive look. Once the correct size is confirmed, sidewall treatment becomes one of the clearest ways to personalize the finished result.
What brands offer tires for the 2006 Buick LaCrosse?
Tires for the 2006 Buick LaCrosse are available from Goodyear, BFGoodrich, and Travelstar, depending on size and style. BFGoodrich appears across both primary sizes with Silvertown Radial and g-Force series choices, while Goodyear and Travelstar appear in the 225/60R16 fitment with distinct sidewall and presentation options.
Brand choice should be weighed alongside tire series, rim-width range, and appearance rather than treated as a simple name preference. One brand may offer a period-style whitewall or redline look, while another may focus on a more performance-oriented blackwall design. The right pick is the one that matches the car’s trim, wheels, and intended character.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Buick LaCrosse?
A period-style 2006 Buick LaCrosse tire choice starts with the correct trim-specific size, then moves to appearance. In 225/60R16, options include redline, pin-white-stripe, wide whitewall, and narrow whitewall radials, while 225/55R17 offers wide whitewall and redline alternatives alongside sportier blackwall choices.
The right selection depends on how original-looking or custom you want the car to appear. A traditional sidewall treatment can emphasize Buick’s comfort-oriented personality, while a simpler blackwall keeps the look cleaner and more contemporary. When exact restoration accuracy matters, compare tire appearance against vehicle photos, dealer literature, or marque-specific references.
How does tire construction affect the appearance of a restored 2006 Buick LaCrosse?
On a 2006 Buick LaCrosse, tire construction is straightforward because the primary fitments are radial. The visible difference comes less from bias-ply versus radial choice and more from the sidewall treatment and tire series, such as blackwall, redline, pin-white-stripe, narrow whitewall, or wide whitewall within the correct radial size.
That means a restored or carefully preserved LaCrosse can take on a noticeably different personality without changing its basic size format. A whitewall can push the car toward a more formal Buick presentation, while blackwall or raised lettering looks more modern. The trim-specific wheel diameter still has to stay correct before appearance decisions are made.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Buick LaCrosse?
Yes, modifications can affect tire fitment on a 2006 Buick LaCrosse even when the tire size sounds close to the original. Wheel changes, altered offsets, suspension lowering, and non-stock springs can influence clearance at the fender, inner wheelhouse, and steering components, especially when moving between the car’s 16-inch and 17-inch fitment families.
A LaCrosse with aftermarket wheels should be checked as it actually sits, not only by model year and trim. Tire width, rim width, and available clearance all matter once the factory setup has changed. Turning the wheels lock to lock and inspecting full suspension travel helps catch rubbing issues before road use.
What should I inspect before driving a 2006 Buick LaCrosse on new tires?
Before driving a 2006 Buick LaCrosse on new tires, inspect wheel condition, verify the tire size matches the installed rim diameter, and confirm proper inflation. It is also wise to check for suspension wear, damaged valve stems, and any signs that the old tires were rubbing or wearing unevenly, since those clues can point to alignment or clearance issues.
A short initial road test is useful after installation. Listen for contact during turns, note any vibration, and recheck pressure after the first drive. Catching a wheel-balance issue, incorrect inflation, or unexpected interference early helps the new tires settle into service without creating uneven wear or avoidable handling problems.
How often should tires on a 2006 Buick LaCrosse be inspected?
Tires on a 2006 Buick LaCrosse should be inspected regularly, especially if the car sees mixed use or spends long periods parked. Look for uneven tread wear, cuts, sidewall cracking, bulges, and air loss. Even on a modern sedan like this one, age and storage conditions can matter as much as mileage in judging tire condition.
A monthly pressure and visual check is a sensible routine, with closer inspection before highway trips or seasonal driving changes. Cars that are driven infrequently deserve extra attention because tires can age quietly while still appearing to have usable tread. Consistent inspection helps protect both ride quality and fitment confidence.
