The 2006 Lexus Trucks RX330 sits in the early wave of luxury crossover SUVs that blended carlike road manners with the everyday utility buyers wanted from a taller vehicle. Its combination of comfort, refinement, and all-weather practicality makes tire choice especially important, because the right fitment affects both stance and driving character. This RX330 uses radial tires in two primary sizes, 225/65R17 and 235/55R18, so the first step is confirming which wheel diameter is on the vehicle. From there, the decision shifts to selecting the right tire style and specification for the intended use, especially if the RX330 has seen wheel changes over time.
Which Tire Size Is Right for The 2006 Lexus Trucks RX330
The 2006 Lexus Trucks RX330 uses two primary tire sizes, and both are radial fitments tied to different wheel diameters. That makes wheel confirmation the first job before choosing a tire, since 225/65R17 fits a 17-inch rim and 235/55R18 fits an 18-inch rim. On the RX330 Base, either size may be present, so the real buying decision starts with the actual wheel on the vehicle rather than the model name alone.
225/65R17 is a metric radial size in which 225 refers to the nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2006 Lexus Trucks RX330, this size is part of the primary fitment range and belongs on a 17-inch wheel. Available product choice in this size is more utility-oriented here, with a BFGoodrich All-Terrain T/A KO2 option featuring an RBL sidewall. It is the size to evaluate when the RX330 is running 17-inch wheels and a more rugged tire character is part of the goal.
235/55R18 is a metric radial size where 235 is the nominal section width in millimeters, 55 is the aspect ratio, R marks radial construction, and 18 identifies the wheel diameter in inches. For the 2006 Lexus Trucks RX330, this is the alternate primary fitment and it applies only when the vehicle is equipped with 18-inch wheels. Its sizing points to a slightly lower-profile package than the 17-inch option, so wheel confirmation matters before any purchase decision. This is the size to focus on when preserving the vehicle's existing 18-inch setup is the priority.
Sub-model fitment is straightforward here because the 2006 Lexus Trucks RX330 Base may use either of the two primary radial tire sizes. The key is not trim identification so much as confirming whether the vehicle is on 17-inch or 18-inch wheels before selecting a tire.

Tire Size & Fitment
What tire size fits a 2006 Lexus Trucks RX330?
The 2006 Lexus Trucks RX330 uses two primary tire sizes: 225/65R17 and 235/55R18. Both are radial sizes, and the correct one depends on which wheel diameter is currently on the vehicle rather than on the model name alone.
A quick wheel check is the most important step before choosing a tire. An RX330 running 17-inch wheels needs the 225/65R17 size, while an RX330 on 18-inch wheels needs 235/55R18. If the vehicle has aftermarket wheels or a changed wheel-and-tire package, confirm the actual rim diameter and overall setup before making a final selection.
What size rim does a 2006 Lexus Trucks RX330 use?
The 2006 Lexus Trucks RX330 uses either a 17-inch or 18-inch rim, depending on which primary tire size is on the vehicle. The 225/65R17 tire pairs with a 17-inch rim, and the 235/55R18 tire pairs with an 18-inch rim.
That difference matters because tire size is tied directly to wheel diameter. A tire built for a 17-inch rim cannot be used on an 18-inch wheel, and the reverse is also true. Checking the size molded into the existing tire sidewall or measuring the wheel setup on the vehicle helps prevent ordering the wrong fitment.
Why does the 2006 Lexus Trucks RX330 have more than one tire size?
The 2006 Lexus Trucks RX330 has more than one tire size because it was fitted with two different wheel diameters. One setup uses 225/65R17 on a 17-inch rim, while the other uses 235/55R18 on an 18-inch rim.
That means the right tire is determined by the actual wheel package on the vehicle. The RX330 Base may appear with either fitment, so trim name alone is not enough. Looking at the sidewall of the current tire or confirming the wheel diameter directly is the safest way to narrow the choice before comparing products.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Lexus Trucks RX330?
Start with the correct primary size for the wheel on the vehicle: 225/65R17 for a 17-inch rim or 235/55R18 for an 18-inch rim. After that, focus on construction, intended use, load capacity, and whether the tire's character suits how the RX330 is actually driven.
Some owners want a more road-oriented replacement, while others may prefer a tougher all-terrain style. Rim compatibility also matters, especially if the vehicle has not remained completely stock. A careful check of wheel diameter, wheel width, and clearance around suspension and body components helps narrow the choice to tires that truly suit the setup.
What brands offer tires for the 2006 Lexus Trucks RX330?
BFGoodrich is represented in the current 2006 Lexus Trucks RX330 product selection, specifically in 225/65R17. The available example is from the All-Terrain T/A KO2 line, which gives this size a more utility-focused option within the vehicle's fitment range.
Brand choice matters most after size and wheel diameter are confirmed. Once the vehicle's 17-inch or 18-inch setup is established, it becomes easier to compare the available brand's sidewall style, load specification, and overall tire character. That approach keeps the decision centered on proper fitment first and product preference second.
What sidewall styles are available for 2006 Lexus Trucks RX330 tires?
An RBL sidewall style is available within the current 225/65R17 product choice for the 2006 Lexus Trucks RX330. On that BFGoodrich option, the sidewall presentation is part of the tire's overall look and can influence whether the vehicle appears more road-oriented or more utility-focused.
Sidewall style should be considered after confirming the correct size and wheel diameter. Appearance can matter, but it should not override fitment, load requirements, or how the RX330 is used. Owners trying to maintain a clean stock-like presentation may weigh sidewall styling differently than those building around a more rugged visual theme.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Lexus Trucks RX330?
A period-style 2006 Lexus Trucks RX330 tire choice starts with keeping the correct primary size for the wheel on the vehicle, either 225/65R17 or 235/55R18. Because this is a modern luxury crossover, the most authentic-looking result usually comes from staying close to the original size format and overall visual proportion.
Appearance should be balanced against how the vehicle is actually used. A more aggressive all-terrain tread can create a different visual statement, while a more road-oriented tire may better preserve the RX330's original character. If exact showroom-era presentation matters, compare the current wheel-and-tire setup against marque-specific reference material before deciding.
Does correct tire fitment matter for a 2006 Lexus Trucks RX330 restoration?
Yes, correct tire fitment matters in a 2006 Lexus Trucks RX330 restoration because wheel diameter and tire proportion strongly affect the vehicle's stance, ride character, and overall finished appearance. Using the proper 17-inch or 18-inch size keeps the restored vehicle visually coherent and avoids obvious fitment mismatches.
Restoration-minded buyers should think beyond simple diameter and look at how the tire fills the wheel opening, how the sidewall presents, and whether the wheel package matches the vehicle's intended presentation. Even on a newer collector vehicle, an incorrect tire size can change the look noticeably and complicate clearance or ride-quality expectations.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Lexus Trucks RX330?
Yes, modifications can affect tire fitment on a 2006 Lexus Trucks RX330. Wheel changes, altered offsets, suspension height changes, or non-stock tire packages can all change how a 225/65R17 or 235/55R18 tire sits within the wheelwell and how much clearance remains during steering and suspension movement.
A modified RX330 should be checked more carefully than one on its original wheel setup. Tire diameter is only part of the equation, since wheel width and placement also matter. Looking at inner clearance, fender clearance, and full-lock steering space helps avoid rubbing issues that may not be obvious when the vehicle is standing still.
What should I inspect before driving a 2006 Lexus Trucks RX330 on new tires?
Before driving a 2006 Lexus Trucks RX330 on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure inflation is set appropriately for the tire in use. Lug hardware, valve stems, and visible clearance around suspension and body components also deserve attention.
A short initial road test can reveal vibration, pulling, or rubbing that should be addressed early. It also helps to recheck air pressure after the first drives and keep an eye on tread wear as the tires settle into service. Those simple steps are especially worthwhile on a vehicle that may have seen prior wheel or suspension changes.
How often should tires on a 2006 Lexus Trucks RX330 be inspected?
Tires on a 2006 Lexus Trucks RX330 should be inspected regularly, not just when tread looks worn. Air pressure, sidewall condition, tread wear pattern, cuts, punctures, and any signs of bulging or cracking are all worth checking on a routine basis, especially if the vehicle sees seasonal or intermittent use.
Frequent inspection matters because a crossover like the RX330 can hide tire issues until they affect ride quality or road manners. Looking over the tires before longer drives is a smart habit, and it becomes even more important if the vehicle sits for extended periods. Storage conditions, age, and gradual air loss can all influence road readiness.
