The 2000 Lexus Trucks RX300 helped define the early luxury crossover formula, combining car-like road manners with the higher seating position and utility many drivers wanted at the turn of the century. For owners keeping one on the road today, tire choice matters because this RX300 uses a single primary size, 225/70R16, in radial construction on a 16-inch rim. That makes the decision less about sorting through multiple factory fitments and more about choosing the right tire style and intended use within that size. A more road-focused restoration-minded approach calls for one kind of look, while a more rugged all-terrain presentation points in another direction.
Which Tire Size Is Right for The 2000 Lexus Trucks RX300
The 2000 Lexus Trucks RX300 uses one primary tire size: 225/70R16, a radial fitment for a 16-inch rim. The 2000 Lexus Trucks RX300 Base uses that same size, so the main decision is not which factory size applies, but which tire style, construction details, and intended-use profile make the most sense for the vehicle you actually drive.
225/70R16 is a metric radial size in which 225 identifies nominal section width in millimeters, 70 is the aspect ratio, R designates radial construction, and 16 is the wheel diameter in inches. On the 2000 Lexus Trucks RX300, this modern radial format matches the vehicle’s single primary fitment and suits buyers looking for a straightforward replacement-size choice. Available product choice in this size includes BFGoodrich’s All Terrain TA KO2 with raised white letter sidewalls. That makes this size especially important for owners balancing everyday road use with a tougher visual stance or light truck-style tire character.
Fitment is straightforward across the covered 2000 Lexus Trucks RX300 sub-models because the same primary tire size is used throughout. Checking the exact sub-model still helps confirm that the vehicle remains on its intended wheel setup before comparing tire styles or usage priorities.

2000 Lexus Trucks RX300 Base
The 2000 Lexus Trucks RX300 Base uses the same 225/70R16 radial fitment as the overall model range. That keeps tire selection focused on intended use, sidewall presentation, and wheel compatibility rather than sorting through multiple primary size 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)
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 2000 Lexus Trucks RX300?
The 2000 Lexus Trucks RX300 uses a 225/70R16 tire size in radial construction. That is the primary fitment for this vehicle, and the covered RX300 Base sub-model uses the same size, so fitment is more straightforward than on vehicles with multiple factory tire options.
Even with one primary size, it is still smart to confirm the wheel setup currently on the vehicle. An RX300 with replacement wheels, altered suspension height, or previous tire substitutions may need closer checking for wheel width, clearance, and overall compatibility before a new 225/70R16 tire is selected.
What size rim does a 2000 Lexus Trucks RX300 use?
The primary tire fitment for the 2000 Lexus Trucks RX300 is built around a 16-inch rim. The 225/70R16 size itself confirms that wheel diameter, and the available product fitment in this size also uses a 16-inch rim.
Rim diameter is only one part of the fitment picture, so wheel width still deserves attention before buying tires. A vehicle that has been modified or fitted with aftermarket wheels may share the same 16-inch diameter while differing in width or offset, both of which can affect tire selection and clearance.
Does the 2000 Lexus Trucks RX300 Base use the same tire size?
Yes. The 2000 Lexus Trucks RX300 Base uses the same 225/70R16 radial tire size as the overall 2000 RX300 fitment. That means there is no separate primary tire-size split within the covered sub-model here.
That consistency simplifies the search, but it does not remove the need to inspect the vehicle itself. If the RX300 Base has non-original wheels or an older set of replacement tires, confirm the wheel diameter, wheel width, and physical clearances before choosing among the available 225/70R16 options.
Choosing the Right Tire
What should I consider when choosing a 225/70R16 tire for a 2000 Lexus Trucks RX300?
Start with the correct primary size, 225/70R16, and make sure the tire matches the vehicle’s 16-inch wheel setup. From there, the real choice is about intended use, sidewall appearance, construction details, and whether the tire’s character suits an RX300 used mainly on pavement or one given a tougher utility-oriented presentation.
Product specifications also matter. Compare rim-width compatibility, load information, weight, and overall tire style before deciding. A more aggressive all-terrain tire can change the vehicle’s visual character and feel, so it helps to match the tire not only to the size requirement but also to how the RX300 is actually driven.
What sidewall styles are available for 2000 Lexus Trucks RX300 tires?
The available 225/70R16 product for the 2000 Lexus Trucks RX300 uses an RWL sidewall, meaning raised white letters. That gives the tire a more assertive, truck-inspired appearance than a plain blackwall presentation and can noticeably change the visual tone of the vehicle.
Sidewall style is largely an appearance decision, but it should still be considered alongside the tire’s overall purpose. On a preserved or lightly used RX300, a raised white letter tire may feel more rugged than stock-looking, while on a utility-focused build it may be exactly the right visual direction.
What brands offer tires for the 2000 Lexus Trucks RX300?
BFGoodrich is represented in the current 225/70R16 product selection for the 2000 Lexus Trucks RX300. The available tire is part of the All Terrain TA KO2 series, giving this size a distinctly more rugged option within the correct overall fitment.
Brand alone should not drive the decision. It makes more sense to compare the tire’s size, wheel compatibility, sidewall treatment, load specification, and intended road use. That approach keeps the focus on how the tire suits the RX300 rather than treating brand name as a shortcut for proper selection.
Restoration & Appearance
Which tire should I choose for a period-style 2000 Lexus Trucks RX300?
A period-style approach for a 2000 Lexus Trucks RX300 starts with keeping the correct 225/70R16 radial size on a 16-inch wheel. That preserves the basic fitment profile, which is more important than chasing an unrelated size that changes the vehicle’s stance or proportions.
Appearance choice then comes down to how closely the tire’s look matches your goal for the vehicle. An all-terrain design with raised white letters creates a more rugged visual statement, while owners seeking a more restrained luxury-crossover presentation may want to compare that look carefully against the vehicle’s overall finish.
Does correct tire fitment matter for a 2000 Lexus Trucks RX300 restoration?
Yes, correct tire fitment matters because tire size has a direct effect on stance, wheel fill, and the overall visual balance of a restored or well-kept 2000 Lexus Trucks RX300. Staying with the proper 225/70R16 size keeps the vehicle closer to its intended proportions.
Construction, sidewall styling, and tread character also influence how authentic or appropriate the finished vehicle feels. Exact originality questions are best checked against model-specific historical references, but keeping the proper size and wheel diameter is the strongest starting point for a restoration-minded tire decision.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2000 Lexus Trucks RX300?
Yes. Even though the 2000 Lexus Trucks RX300 uses a straightforward 225/70R16 fitment, modifications can still affect whether a given tire remains a comfortable match for the vehicle. Wheel changes, suspension alterations, or body modifications can all influence clearance and how the tire sits on the vehicle.
An RX300 with aftermarket wheels should be checked for wheel width, offset, and any signs of rubbing at full steering lock or suspension travel. Looking at the actual setup before buying avoids assuming that the correct nominal tire size automatically means the entire wheel-and-tire package is still compatible.
What should I inspect before driving a 2000 Lexus Trucks RX300 on new tires?
Before putting a 2000 Lexus Trucks RX300 back on the road with new tires, inspect the wheels for damage, confirm proper wheel diameter and width, and make sure the suspension and steering components are in sound condition. Tire pressure should also be set correctly, and any signs of uneven prior wear deserve attention.
A short clearance check is worthwhile after installation, especially if the vehicle has had wheel or suspension changes over the years. It also helps to watch for vibration, pulling, unusual noise, or contact marks during the first drives so any fitment or chassis issue can be corrected early.
How should 225/70R16 tires on a collector 2000 Lexus Trucks RX300 be maintained?
225/70R16 tires on a collector or low-use 2000 Lexus Trucks RX300 should be inspected regularly for cracking, cuts, bulges, embedded debris, and gradual air loss. Tread condition matters, but age and storage condition matter just as much on a vehicle that may spend long periods parked between drives.
Good maintenance also includes keeping the tires properly inflated and storing the vehicle away from prolonged sunlight, moisture, and ozone sources when possible. Moving the RX300 occasionally and checking the tires before each outing helps catch age-related issues early, even when the tread still looks serviceable.
