The 1999 Panoz AIV Roadster belongs to a very small circle of late-1990s American performance cars that mixed hand-built character with serious modern hardware. Its aluminum-intensive roadster layout and front-engine, rear-drive balance give tire selection a bigger role than on an ordinary contemporary sports car. This setup uses staggered radial fitment, with 245/40R18 at the front and 295/35R18 at the rear, both on 18-inch rims. Available choices include blackwall performance radials as well as redline and raised white letter styles in the proper sizes. The real priority is preserving the intended front-to-rear balance while matching the tire's appearance and road-use goal to the car.
Which Tire Size Is Right for The 1999 Panoz AIV Roadster
The 1999 Panoz AIV Roadster uses two primary tire sizes, and the split is determined by position rather than alternate trim fitment. A 245/40R18 radial is used at the front and a 295/35R18 radial is used at the rear, both on 18-inch wheels. The first step is confirming which end of the car you are replacing tires on, then comparing brand, sidewall style, and intended use within the correct size.
295/35R18 is a metric radial size with a 295-millimeter nominal section width, a 35-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 1999 Panoz AIV Roadster, this is the rear tire size, giving the car its wider back-tire stance and helping maintain the intended staggered setup. Current choices center on Pro-Trac Street Pro III tires with redline or RWL sidewall styling. This size should be evaluated as a rear fitment, with attention paid to wheel width, rear clearance, and keeping the front-to-rear combination consistent.
Sub-model fitment on the 1999 Panoz AIV Roadster is straightforward, but it is split by front and rear position. Checking the exact position matters because the car uses a staggered tire setup rather than the same size at all four corners.

1999 Panoz AIV Roadster Base Front
The Base Front fitment uses the narrower front tire size in radial construction on an 18-inch rim. That makes the key decision less about whether another primary size applies and more about choosing the right front tire style, brand, and performance character for the car's steering end.
The Base Rear fitment uses the wider rear radial size on an 18-inch rim, giving the car its staggered stance and rear-tire footprint. Tire selection here should focus on maintaining the proper rear size while comparing sidewall presentation and wheel compatibility before mixing brands or series.
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 1999 Panoz AIV Roadster?
The 1999 Panoz AIV Roadster uses a staggered tire setup rather than one size at all four corners. The front tire size is 245/40R18 and the rear tire size is 295/35R18, both in radial construction on 18-inch rims.
That means the first fitment question is position on the car, not trim level in the usual sense. Matching the front and rear sizes correctly helps preserve the car's intended balance, stance, and clearance. Before selecting replacements, confirm whether you are replacing only the fronts, only the rears, or building a complete matched set.
What size rim does a 1999 Panoz AIV Roadster use?
The 1999 Panoz AIV Roadster uses 18-inch rims with both of its primary tire sizes. The front 245/40R18 and rear 295/35R18 are both built around the same 18-inch rim diameter, even though the tire widths and profiles differ.
Rim diameter is only one part of the fitment picture on a staggered sports car. Wheel width still matters, especially when comparing among available tires with different rim-width specifications. If the car has replacement wheels, verify the actual wheel dimensions before assuming the existing tire size or series is still the right match.
Why does the 1999 Panoz AIV Roadster have more than one tire size?
The 1999 Panoz AIV Roadster has more than one tire size because it uses a front-and-rear staggered setup. The front position takes 245/40R18, while the rear uses the wider 295/35R18, so the two sizes serve different roles on the car.
This matters because a staggered fitment is part of the car's overall setup, not just an appearance detail. Tire replacement should be planned by axle position, and any change in width, series, or wheel dimensions needs to be checked carefully. Keeping the proper front and rear sizes helps avoid introducing avoidable clearance or handling issues.
Choosing the Right Tire
What should I consider when choosing a 245/40R18 or 295/35R18 tire for a 1999 Panoz AIV Roadster?
Start with the correct position-specific size, since the 1999 Panoz AIV Roadster uses 245/40R18 in front and 295/35R18 in the rear. Both are radial tires on 18-inch rims, so the next considerations are wheel compatibility, intended use, and whether the tire's appearance suits the car.
Available options vary by brand, tire series, sidewall style, and in some cases rim-width specification, weight, and load rating. A street-driven car may call for a different choice than one focused on specialty use or a stronger period-inspired look. On a staggered setup, it also makes sense to choose front and rear tires that complement each other visually and functionally.
What sidewall styles are available for 1999 Panoz AIV Roadster tires?
Sidewall choices for the 1999 Panoz AIV Roadster include blackwall, redline, and RWL styles, depending on tire size and series. Blackwall options are available in the front 245/40R18 size, while Pro-Trac Street Pro III tires bring redline and raised white letter presentation into both front and rear fitments.
That gives the car noticeably different visual directions without changing the basic staggered sizing. Blackwalls suit a more understated modern-performance look, while redline and RWL treatments create a more stylized or retro-inspired presentation. The key is choosing a sidewall style that works with the roadster's character while still keeping the correct size at each end.
What brands offer tires for the 1999 Panoz AIV Roadster?
Tires for the 1999 Panoz AIV Roadster are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac in the applicable sizes. The front 245/40R18 size has the broadest range, while current rear 295/35R18 choices center on Pro-Trac offerings.
Brand choice should be treated as part of a larger fitment decision rather than a shortcut. Tire series, sidewall style, wheel-width compatibility, and intended use can matter just as much as the name on the sidewall. On a car with staggered sizing, compare the available front and rear options together so the complete setup makes sense.
Restoration & Appearance
Which tire should I choose for a period-style 1999 Panoz AIV Roadster?
A period-style 1999 Panoz AIV Roadster still starts with the correct staggered sizes: 245/40R18 front and 295/35R18 rear. From there, the visual direction comes from the tire series and sidewall treatment, with blackwall, redline, and RWL options offering very different presentations.
Because this is a late-1990s specialty performance car, appearance choices often come down to whether the goal is a cleaner modern look or something with more muscle-era influence. Redline or raised white letter tires can change the roadster's personality quickly. For exact originality questions, marque-specific historical references remain the better standard than appearance alone.
How does tire construction affect the appearance of a restored 1999 Panoz AIV Roadster?
Tire construction is simpler on the 1999 Panoz AIV Roadster than on many older collector vehicles because its primary fitment is already radial. The visual difference comes less from bias-ply versus radial choice and more from the tire's tread style, sidewall treatment, and overall performance-oriented profile.
That makes sidewall styling especially important during a restoration-minded tire search. A blackwall radial keeps the look contemporary and restrained, while redline or RWL versions create a more assertive, custom-leaning presentation. Staying with the correct front and rear sizes is still the foundation, since proportions are a major part of how this roadster sits.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1999 Panoz AIV Roadster?
Yes, modifications can affect tire fitment on a 1999 Panoz AIV Roadster, especially because the car uses a staggered 18-inch setup with different front and rear widths. Changes to wheel width, wheel offset, suspension height, alignment, or body clearance can alter how a 245/40R18 front or 295/35R18 rear tire sits on the car.
A modified roadster should be checked more carefully than a stock one before ordering replacements. Look at steering clearance up front, inner and outer clearance at the rear, and any signs of rubbing on suspension or bodywork. Even when the tire size stays the same, wheel changes can shift the fitment enough to require another review.
What should I inspect before driving a 1999 Panoz AIV Roadster on new tires?
Before driving a 1999 Panoz AIV Roadster on new tires, inspect wheel condition, verify the front and rear sizes are mounted in the correct positions, and check inflation pressure. It also makes sense to look over suspension and steering components, since worn parts can undermine the benefit of a fresh set of tires.
A short test drive should be used to confirm there is no rubbing, vibration, or unexpected pull. After that, recheck air pressure and give the tires another visual inspection for any contact marks. On a low-production performance car, catching a mounting or clearance problem early is much easier than correcting damage after more road time.
How often should tires on a 1999 Panoz AIV Roadster be inspected?
Tires on a 1999 Panoz AIV Roadster should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Collector-oriented performance cars can accumulate tire age without accumulating much mileage, so tread depth alone is not enough to judge condition.
Routine checks should include air pressure, tread wear pattern, sidewall cracking, bulges, cuts, and signs of slow air loss. It is also smart to inspect before a longer drive or after seasonal storage, since flat spotting and age-related issues can appear even when the car has seen limited use. Consistent inspection helps preserve both safety and drivability.
