The 2004 Buick Park Avenue sits at the end of Buick’s long-running full-size front-wheel-drive luxury sedan tradition, blending a smooth highway character with the roomy, formal presence many Park Avenue owners still appreciate. For tire selection, the key detail is that this model uses two different radial sizes depending on sub-model: 225/60R16 or 235/55R17. That means the first step is confirming whether the car is a Base, Ultra, or w/Prestige Pkg. configuration. From there, the choice shifts to sidewall style, tire series, and overall presentation, whether the goal is a clean road-going replacement or a more restoration-minded whitewall, redline, or specialty look.
Which Tire Size Is Right for The 2004 Buick Park Avenue
The 2004 Buick Park Avenue uses two primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Both fitments are radial, but one uses a 16-inch rim and the other uses a 17-inch rim, so confirming the vehicle’s wheel setup comes first. Once that is settled, the real decision becomes choosing the right brand, sidewall treatment, and tire character within the proper size.
225/60R16 is a modern metric radial size in which 225 identifies the nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 16 is the rim diameter in inches. On the 2004 Buick Park Avenue, this size is used on 16-inch wheel applications and suits buyers staying with the original wheel diameter for the Base or w/Prestige Pkg. setup. Available choices include Goodyear, BFGoodrich, and Travelstar, with sidewall treatments such as raised yellow letter, redline, pin white stripe, wide whitewall, and narrow whitewall. It is the right place to start when appearance matters as much as basic fitment.
235/55R17 is also a modern metric radial size, with 235 representing nominal section width in millimeters, 55 indicating the aspect ratio, R marking radial construction, and 17 calling for a 17-inch rim. On the 2004 Buick Park Avenue, this size belongs to the 17-inch wheel configuration used by the Ultra. Product choices range from blackwall performance-oriented designs to goldline, redline, and wide whitewall options from American Classic and Coker Classic, along with BFGoodrich selections. This size deserves close attention if the car has Ultra trim or if wheel changes may have altered the original setup.
Sub-model fitment matters on the 2004 Buick Park Avenue because the tire size changes with the specific configuration. The Base and w/Prestige Pkg. models share one radial size, while the Ultra uses a different size and rim diameter, so verifying the exact sub-model prevents an easy ordering mistake.

2004 Buick Park Avenue Base
The 2004 Buick Park Avenue Base uses the 225/60R16 radial fitment on a 16-inch wheel. That keeps tire selection focused on style and product character, with options that range from more understated road-use choices to whitewall, stripe, or specialty sidewall presentations.
The 2004 Buick Park Avenue Ultra uses the 235/55R17 radial fitment on a 17-inch wheel. Tire selection here begins with confirming the larger wheel diameter, then narrowing the choice by blackwall, redline, goldline, or whitewall appearance depending on how the car is used and presented.
The 2004 Buick Park Avenue w/Prestige Pkg. uses the same 225/60R16 radial size as the Base model. That shared fitment makes size selection straightforward, leaving the buyer to compare brands, sidewall styles, and rim-width specifications within the correct 16-inch application.
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.

Common questions for the 2004 Buick Park Avenue usually come down to confirming the correct tire size by sub-model, matching the right 16-inch or 17-inch wheel, and choosing between available sidewall styles, brands, and road-use priorities.
Tire Size & Fitment
What tire size fits a 2004 Buick Park Avenue?
A 2004 Buick Park Avenue uses either 225/60R16 or 235/55R17, depending on the sub-model. The Base and w/Prestige Pkg. models use 225/60R16, while the Ultra uses 235/55R17. Both are radial tire fitments tied to different wheel diameters.
The important step is matching the tire size to the car’s actual wheel setup rather than assuming all Park Avenue models are the same. A 16-inch tire does not belong on a 17-inch rim, and an Ultra should be checked carefully if the car has had wheel changes at some point in its life.
What size rim does a 2004 Buick Park Avenue use?
The 2004 Buick Park Avenue uses either a 16-inch or 17-inch rim, depending on the sub-model. The 225/60R16 fitment uses a 16-inch rim, and the 235/55R17 fitment uses a 17-inch rim. Rim diameter follows the last number in each tire size.
Wheel diameter is the first thing to confirm before selecting tires for this model. It is also worth checking the actual wheels on the car if it has aftermarket rims or if a previous owner changed the setup, since the Park Avenue was offered with both 16-inch and 17-inch applications.
Do all 2004 Buick Park Avenue sub-models use the same tire size?
No, not all 2004 Buick Park Avenue sub-models use the same tire size. The Base and w/Prestige Pkg. models use 225/60R16, while the Ultra uses 235/55R17. The difference also means a change in rim diameter from 16 inches to 17 inches.
That split makes the exact sub-model an essential part of tire selection. Buyers should confirm the trim level and inspect the wheels currently on the car, especially on older luxury sedans that may have seen replacement wheels, tire substitutions, or cosmetic changes over time.
Choosing the Right Tire
What should I consider when choosing a tire for a 2004 Buick Park Avenue?
Start with the correct size for the exact sub-model, since the 2004 Buick Park Avenue uses either 225/60R16 or 235/55R17. After that, compare radial construction details such as brand, tire series, sidewall style, load specification, and the rim-width range attached to the specific product.
A clean touring look may point toward blackwall or narrow whitewall choices, while a more distinctive presentation may favor redline, goldline, pin white stripe, or wide whitewall designs. The right choice depends on whether the car is kept close to its original visual character, shown occasionally, or driven regularly.
What sidewall styles are available for 2004 Buick Park Avenue tires?
Sidewall choices for the 2004 Buick Park Avenue include Raised-Yellow-Letter, Redline, Pin-White-Stripe, Wide Whitewall, Narrow Whitewall, Blackwall, and Goldline, depending on tire size and product line. Those styles are spread across both the 225/60R16 and 235/55R17 radial fitments.
The sidewall treatment can change the car’s visual character as much as the wheel itself. A blackwall keeps the presentation understated, while whitewalls, redlines, goldlines, or raised lettering create a more deliberate period-inspired look, so it helps to decide whether appearance or a more neutral replacement style is the priority.
What brands offer tires for the 2004 Buick Park Avenue?
Tires for the 2004 Buick Park Avenue are available from Goodyear, BFGoodrich, Travelstar, American Classic, and Coker Classic, depending on the size. Brand availability differs between the 225/60R16 and 235/55R17 fitments, so the exact sub-model still determines which products are relevant.
Brand choice should be considered alongside sidewall style, tire series, and wheel-width compatibility rather than in isolation. A buyer comparing products for a Park Avenue usually gets the best result by narrowing the correct size first and then choosing the tire that matches the car’s intended appearance and driving use.
Restoration & Appearance
Which tire should I choose for a period-style 2004 Buick Park Avenue?
A period-style 2004 Buick Park Avenue tire starts with the correct sub-model size, then moves to visual presentation. On 225/60R16, choices include redline, pin white stripe, wide whitewall, and narrow whitewall styles, while 235/55R17 includes redline, goldline, and wide whitewall options alongside blackwall designs.
The most suitable look depends on how closely the car is being returned to its early-2000s luxury-sedan character versus a more personalized collector presentation. Buyers pursuing exact historical accuracy should compare the current tire choice against original vehicle literature, period photos, or marque-specific reference material before settling on a stripe or whitewall style.
Does correct tire fitment matter for a 2004 Buick Park Avenue restoration?
Yes, correct tire fitment matters because the 2004 Buick Park Avenue used two different sizes tied to different sub-models and wheel diameters. Using the proper 225/60R16 or 235/55R17 fitment helps preserve the car’s stance, wheel relationship, and overall visual balance far better than an arbitrary substitute.
Appearance is only part of the equation. Keeping the right size also helps avoid unnecessary fitment issues at the fender, steering, or suspension, especially on a car that may already have aged components or replacement wheels. Restoration-minded buyers should confirm the trim level first and then choose the sidewall style that suits the project.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Buick Park Avenue?
Yes, modifications can affect tire fitment on a 2004 Buick Park Avenue. Wheel swaps, suspension changes, lowering, or replacement parts that alter ride height or clearance can all change how a 225/60R16 or 235/55R17 tire sits in the wheel opening and how much room it has while turning.
That is especially important on an older luxury sedan that may no longer be on its original wheels. Before buying tires, inspect the actual rim diameter and width on the car, then look for signs of limited clearance around the fenders, strut area, and steering range so the chosen size matches the present setup.
What should I inspect before driving a 2004 Buick Park Avenue on new tires?
Before driving a 2004 Buick Park Avenue on new tires, check that the tire size matches the sub-model and wheel diameter, then inspect the wheels themselves for damage or excessive corrosion. Tire pressure should be set correctly, and the suspension, steering, and alignment condition should be good enough to support even tire wear.
A brief close inspection also helps catch problems that new tires cannot solve, such as loose front-end parts or rubbing caused by altered wheels. After installation, watch for vibration, pull, unusual noise, or contact at full lock, since those signs can point to a setup issue rather than a tire defect.
How often should tires on a 2004 Buick Park Avenue be inspected?
Tires on a 2004 Buick Park Avenue should be inspected regularly, even if the car is driven only occasionally. Collector and low-mileage vehicles can develop age-related problems such as sidewall cracking, flat spotting, or slow air loss long before the tread is actually worn out.
A smart routine is to inspect them before longer drives and at intervals during normal use for cuts, bulges, uneven wear, and pressure loss. Cars that spend long periods parked also benefit from proper inflation, clean storage conditions, and occasional movement so the tires and suspension are not sitting in one position for months.
