The 2000 Pontiac Grand Prix came from the final years of Pontiac’s front-wheel-drive midsize performance sedan era, when aggressive styling and trim-level separation gave the car a distinctly sporty identity. Tire fitment follows that split: GT and GTP models use 225/60R16 radials, while the SE uses 205/70R15 radials. That means the first step is confirming the exact sub-model and wheel diameter before choosing a tire. Available options range from blackwall and whitewall treatments to redline, raised yellow letter, and period-inspired radial designs from brands including Goodyear, BFGoodrich, Michelin, Dunlop, and others. The right choice depends on whether the goal is stock-size road use, a restoration-minded look, or a more specialized presentation.
Which Tire Size Is Right for The 2000 Pontiac Grand Prix
Two primary tire sizes apply to the 2000 Pontiac Grand Prix, and the correct one depends on the sub-model as well as wheel diameter. GT and GTP models use a 16-inch fitment, while the SE uses a 15-inch fitment, so identifying the exact trim and confirming the wheels on the car should come before comparing brands, sidewall styles, or tire series.
225/60R16 is a metric radial size in which 225 identifies the section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 16 is the rim diameter in inches. On the 2000 Pontiac Grand Prix, this size is used on GT and GTP models and keeps the fitment centered on a modern radial construction. 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 makes sense when the car retains its 16-inch wheel setup and the goal is to match the proper trim-level fitment while choosing the appearance that suits the car.
205/70R15 is a metric radial size where 205 is the nominal section width in millimeters, 70 is the aspect ratio, R marks radial construction, and 15 is the rim diameter in inches. On the 2000 Pontiac Grand Prix, this size is associated with the SE and opens up a broad mix of product styles within the same basic fitment. Choices include blackwall, narrow whitewall, and wide whitewall designs from brands such as Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. It is the right place to focus when the car is an SE or when a Grand Prix has retained its original 15-inch wheel format.
Sub-model fitment matters on the 2000 Pontiac Grand Prix because tire size changes with trim. GT and GTP share the same 16-inch radial size, while the SE uses a different 15-inch radial fitment, so confirming the exact version of the car helps prevent choosing the wrong wheel diameter.

2000 Pontiac Grand Prix GT
The 2000 Pontiac Grand Prix GT uses the 225/60R16 radial tire size. Tire selection here is less about sorting through multiple primary sizes and more about choosing the right brand, sidewall style, and overall presentation for a 16-inch wheel setup.
The 2000 Pontiac Grand Prix GTP also uses the 225/60R16 radial size. That keeps fitment straightforward as long as the car still has the proper 16-inch wheels, letting the decision shift toward appearance details such as raised-letter, redline, or whitewall styling.
The 2000 Pontiac Grand Prix SE uses the 205/70R15 radial tire size rather than the 16-inch fitment found on the upper trims. That means wheel diameter should be confirmed first, then product choices can be narrowed by sidewall treatment, tire series, and intended use.
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.

These FAQs focus on the tire-size split between Grand Prix sub-models, 15-inch versus 16-inch wheel fitment, available radial styles, and the practical checks that matter before putting a 2000 Pontiac Grand Prix back on the road.
Tire Size & Fitment
What tire size fits a 2000 Pontiac Grand Prix?
A 2000 Pontiac Grand Prix uses either 225/60R16 or 205/70R15, depending on the sub-model. GT and GTP models use 225/60R16 radial tires, while the SE uses 205/70R15 radial tires. Both are modern metric radial sizes, but they mount on different rim diameters and should not be treated as the same fitment.
The important next step is confirming which trim level and wheel size the car actually has today. A Grand Prix that has had wheels changed over the years may no longer match its original sub-model fitment, so checking the current wheel diameter and the tire size already on the car helps avoid choosing the wrong size.
What size rim does a 2000 Pontiac Grand Prix use?
The 2000 Pontiac Grand Prix uses either a 16-inch rim or a 15-inch rim, depending on the sub-model. The 225/60R16 fitment used on GT and GTP models goes with a 16-inch wheel, while the 205/70R15 fitment used on the SE goes with a 15-inch wheel.
Rim diameter is the first thing to verify before shopping because a 15-inch tire cannot be mounted on a 16-inch wheel, and the reverse is also true. If the car has aftermarket wheels, confirm the actual wheel diameter and width before comparing tire choices, especially when moving between stock-style and appearance-oriented products.
Do all 2000 Pontiac Grand Prix sub-models use the same tire size?
No, the 2000 Pontiac Grand Prix does not use one tire size across all sub-models. GT and GTP models share the 225/60R16 radial size, while the SE uses 205/70R15. The difference is tied to the trim level, so the correct tire starts with identifying the exact version of the car.
That distinction matters because the two sizes use different wheel diameters and open up different product assortments. Once the sub-model is confirmed, the decision becomes much easier, since tire shopping can focus on the proper size first and then move to sidewall styling, tire series, and other product characteristics within that correct fitment.
Choosing the Right Tire
What should I consider when choosing a 225/60R16 tire for a 2000 Pontiac Grand Prix?
Start by confirming that the car is a GT or GTP and that it still uses the proper 16-inch wheels. Within 225/60R16, available choices include Goodyear, BFGoodrich, and Travelstar radials, with sidewall styles such as raised yellow letter, redline, pin white stripe, wide whitewall, and narrow whitewall.
After size is settled, compare the tire’s visual style, intended use, and wheel-width compatibility. A raised-letter tire creates a very different impression than a whitewall or redline, even though the basic fitment remains the same, so the best choice is the one that matches the car’s trim, presentation, and actual wheel setup.
What sidewall styles are available for 2000 Pontiac Grand Prix tires?
Sidewall options for the 2000 Pontiac Grand Prix vary by tire size, but the available styles include blackwall, narrow whitewall, wide whitewall, redline, pin white stripe, and raised yellow letter. The 225/60R16 fitment shows the broadest visual variety, while 205/70R15 also offers several blackwall and whitewall options.
Choosing among them is mostly an appearance decision once the correct tire size is established. A blackwall keeps the look understated, whitewalls lean more traditional, and redline or raised-letter designs create a stronger period-inspired performance look, so the visual direction of the car should guide the final pick.
What brands offer tires for the 2000 Pontiac Grand Prix?
Brand availability for the 2000 Pontiac Grand Prix includes Goodyear, BFGoodrich, Travelstar, Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, and Tornel. Not every brand appears in both primary sizes, so the available selection depends first on whether the car uses 225/60R16 or 205/70R15.
Brand comparison should come after the correct fitment is locked in. Once that is settled, the more useful differences are often sidewall style, tire series, rim-width compatibility, load figures where stated, and whether the tire is aimed at a stock-looking road car, a collector presentation, or a more specialized vintage-inspired application.
Restoration & Appearance
Which tire should I choose for a period-style 2000 Pontiac Grand Prix?
A period-style choice for a 2000 Pontiac Grand Prix starts with using the correct size for the sub-model: 225/60R16 for GT and GTP, or 205/70R15 for SE. From there, the most appearance-driven options are usually the sidewall treatments, including raised yellow letter, redline, pin white stripe, narrow whitewall, and wide whitewall.
The right look depends on how the car is being presented. A sportier Grand Prix may suit raised-letter or redline styling, while a cleaner restoration-oriented appearance may lean toward blackwall or one of the whitewall options. Exact originality questions are best checked against trim-specific period references if the goal is a highly accurate restoration.
How does tire construction affect the appearance of a restored 2000 Pontiac Grand Prix?
For the 2000 Pontiac Grand Prix, the primary fitments are radial tires, so construction choice is less about switching from an older bias-ply format and more about selecting the visual style within a radial tire. The appearance difference usually comes from the sidewall treatment and tire series rather than the basic radial construction itself.
That makes details like blackwall versus whitewall, or redline versus raised lettering, especially important on a restored car. Even when the size is correct, a tire can change the personality of the vehicle considerably, so the best visual result comes from matching the sidewall style to the trim level, wheels, and overall restoration theme.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2000 Pontiac Grand Prix?
Yes, modifications can affect tire fitment on a 2000 Pontiac Grand Prix even when the tire size appears close to stock. Wheel changes, altered wheel width, suspension modifications, lowering, or body changes can all influence how a 225/60R16 or 205/70R15 tire sits and whether it has adequate clearance.
A Grand Prix with aftermarket wheels should be checked carefully before ordering replacement tires. Wheel diameter, width, and overall tire dimensions all matter, and steering or fender clearance can change from one setup to another, so the safest approach is to verify the current hardware on the car rather than assuming stock fitment still applies.
What should I inspect before driving a 2000 Pontiac Grand Prix on new tires?
Before driving a 2000 Pontiac Grand Prix on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure each tire is inflated properly. It also helps to look over the suspension, steering components, and alignment condition so the new tires are not immediately affected by an underlying chassis issue.
A short road test should include listening for rubbing, checking straight-line behavior, and rechecking air pressure after the first miles. Collector and occasional-use cars deserve extra attention because a Grand Prix that sits for long periods may have age-related issues elsewhere in the chassis, even when the tires themselves are brand new.
How often should tires on a 2000 Pontiac Grand Prix be inspected?
Tires on a 2000 Pontiac Grand Prix should be inspected regularly, especially if the car is driven infrequently. Tread wear, air loss, sidewall cracking, bulges, cuts, and uneven wear patterns are all worth watching, whether the car runs 225/60R16 on a GT or GTP or 205/70R15 on an SE.
A quick visual check before each drive is a sensible habit, with a more thorough inspection done periodically during the driving season. Cars that spend time in storage should also have tire pressure monitored and be kept away from prolonged sunlight, moisture, and ozone sources, since age and storage conditions matter as much as mileage on many older vehicles.
