The 2009 Lexus Trucks RX350 blends car-like ride quality with the everyday versatility that helped define the modern luxury crossover. Buyers still turn to this generation for comfortable highway use, family duty, and long-service dependability, which makes correct tire selection especially important. This RX350 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. Because both front-wheel-drive and all-wheel-drive versions can use either size, the real choice often comes down to matching the tire to the installed wheels, intended road use, and the overall look and stance you want to preserve.
Which Tire Size Is Right for The 2009 Lexus Trucks RX350
Two tire sizes apply to the 2009 Lexus Trucks RX350, and the most important first step is confirming whether the vehicle is equipped with 17-inch or 18-inch wheels. Both sizes are radial constructions, and both FWD and AWD models can use either one, while the Pebble Beach Edition uses 235/55R18. Once wheel diameter is confirmed, the decision shifts to selecting the right tire style and specifications for how the vehicle is driven.
The 225/65R17 size reads as a 225-millimeter section width, a 65-series aspect ratio, radial construction, and fitment on a 17-inch rim. On the 2009 Lexus Trucks RX350, this is one of the standard radial sizes and is used on both AWD and FWD configurations, so wheel diameter is the key fitment check before moving forward. Available product coverage in this size includes an all-terrain style option from BFGoodrich with an RBL sidewall and All Terrain TA KO2 series construction. This size is worth considering when the RX350 is already on 17-inch wheels and the goal is to match the vehicle's existing wheel setup carefully.
The 235/55R18 size indicates a 235-millimeter section width, a 55-series profile, radial construction, and fitment on an 18-inch rim. For the 2009 Lexus Trucks RX350, this size appears across both AWD and FWD versions and is also the tire size used on the Pebble Beach Edition, making wheel confirmation more important than drivetrain alone. Its lower-profile metric format gives it a different sizing presentation than the 17-inch option even though both are modern radial fitments. This is the size to evaluate when the vehicle is equipped with 18-inch wheels and the tire choice needs to stay aligned with that rim diameter.
Sub-model fitment is mostly straightforward on the 2009 Lexus Trucks RX350, but wheel diameter still matters because more than one tire size can apply. AWD and FWD versions can use either primary size, while the Pebble Beach Edition centers the decision on 18-inch fitment.

2009 Lexus Trucks RX350 (AWD)
The 2009 Lexus Trucks RX350 (AWD) can use either of the model's two primary radial tire sizes, so drivetrain alone does not narrow the choice to one fitment. Tire selection comes down to confirming whether the vehicle has 17-inch or 18-inch wheels before comparing available tire styles and specifications.
The 2009 Lexus Trucks RX350 (FWD) also spans both primary radial tire sizes, which means the installed wheel diameter determines the correct fitment path. Once that is confirmed, the buyer can focus on choosing a tire that suits the vehicle's road use and overall setup.
The 2009 Lexus Trucks RX350 Pebble Beach Edition uses the 18-inch radial fitment rather than the 17-inch alternative found elsewhere in the model range. That makes tire selection more direct, with the focus shifting from size identification to choosing the right product characteristics within the correct 18-inch setup.
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.

Product comparisons in the grid are most useful when reviewed alongside wheel diameter, rim-width compatibility, load rating, and intended use.
These FAQs focus on the tire sizes used on the 2009 Lexus Trucks RX350, how wheel diameter affects fitment, and what to review when choosing tires for everyday driving, replacement planning, and road-use safety.
Tire Size & Fitment
What tire size fits a 2009 Lexus Trucks RX350?
The 2009 Lexus Trucks RX350 uses two primary tire sizes: 225/65R17 and 235/55R18. Both are radial tire sizes, and both AWD and FWD versions can be found with either fitment, while the Pebble Beach Edition uses 235/55R18.
The practical first step is checking the wheel diameter actually installed on the vehicle, because a 17-inch tire and an 18-inch tire are not interchangeable. Once that is confirmed, tire selection becomes much easier, since the buyer can focus on the correct size and then compare tire type, sidewall style, load specification, and intended road use.
What size rim does a 2009 Lexus Trucks RX350 use?
The 2009 Lexus Trucks RX350 uses either a 17-inch or 18-inch rim, depending on which tire size is on the vehicle. The 225/65R17 tire fits a 17-inch rim, and the 235/55R18 tire fits an 18-inch rim.
That makes wheel confirmation the most important fitment check before ordering replacement tires. Looking at the sidewall size marking is usually the quickest way to verify what is already on the vehicle, but it is also smart to confirm the actual wheel setup if the RX350 has had wheel changes, trim swaps, or other modifications during its service life.
Do all 2009 Lexus Trucks RX350 sub-models use the same tire size?
Not every 2009 Lexus Trucks RX350 sub-model uses one single tire size across the board. AWD and FWD versions can use either 225/65R17 or 235/55R18, while the Pebble Beach Edition uses 235/55R18.
That means sub-model name alone does not always answer the fitment question, especially on standard AWD and FWD versions. The safest approach is to confirm both the sub-model and the wheel diameter on the vehicle, since tire size follows the installed 17-inch or 18-inch wheel rather than drivetrain by itself.
Choosing the Right Tire
What should I consider when choosing a tire for a 2009 Lexus Trucks RX350?
Start by confirming whether the RX350 is on 225/65R17 or 235/55R18 tires, since the correct size depends on the wheel diameter. After size is verified, compare construction details, load specification, rim-width compatibility, sidewall style, and the kind of driving the vehicle actually sees.
A replacement tire for a daily-driven crossover may be chosen differently than one for occasional use or rougher road conditions. It also helps to look at the existing wheel setup, suspension condition, and whether the vehicle has remained stock, because those factors can influence how well a given tire choice matches the RX350's current configuration.
What sidewall styles are available for 2009 Lexus Trucks RX350 tires?
Current product coverage for the 2009 Lexus Trucks RX350 includes an RBL sidewall style in 225/65R17. RBL refers to a raised black letter sidewall, which gives the tire a more pronounced utility-oriented appearance than a plain blackwall treatment.
Sidewall style affects appearance more than fitment, but it can still shape how the vehicle presents overall. On an RX350, that choice may matter if the goal is to keep a cleaner factory-inspired look or move toward a more rugged visual style, especially when paired with an all-terrain tire series and the vehicle's existing wheel design.
What brands offer tires for the 2009 Lexus Trucks RX350?
Available product coverage for the 2009 Lexus Trucks RX350 includes BFGoodrich in 225/65R17. That option appears in the All Terrain TA KO2 series and uses radial construction.
Brand is only one part of the decision, so it should be weighed alongside the correct size, rim compatibility, load capacity, and the type of use the vehicle sees. A tire that suits an RX350 used on pavement every day may be chosen for different reasons than one installed on a vehicle that regularly encounters gravel roads or rougher surfaces.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Lexus Trucks RX350?
A period-style choice for a 2009 Lexus Trucks RX350 usually starts with keeping the correct original-size format already used on the vehicle, either 225/65R17 or 235/55R18. Since this is a modern crossover with radial fitments, the main appearance decision is less about vintage construction and more about staying consistent with wheel diameter and overall presentation.
Owners who want the RX350 to retain a clean, era-appropriate look should avoid treating size changes as purely cosmetic. Matching the installed wheel size, maintaining a balanced sidewall profile, and choosing a tread and sidewall style that suits the vehicle's character will usually preserve the most natural appearance for this generation.
Does correct tire fitment matter for a 2009 Lexus Trucks RX350 restoration?
Correct tire fitment matters on a 2009 Lexus Trucks RX350 because the vehicle's stance, wheel-to-tire proportion, and everyday drivability all depend on using the proper size for the wheel. Even on a newer collector-era vehicle, the wrong tire diameter or rim match can change the look and feel noticeably.
Restoration-minded owners should confirm what wheel package the vehicle is wearing before replacing tires, especially if the RX350 has changed hands or had later wheel swaps. Keeping the tire size aligned with the correct 17-inch or 18-inch setup helps preserve a more coherent appearance while also reducing the chance of clearance or compatibility problems.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Lexus Trucks RX350?
Yes, modifications can affect tire fitment on a 2009 Lexus Trucks RX350. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body modifications can all change how a 225/65R17 or 235/55R18 tire sits in the wheel opening.
That matters even when the tire size itself sounds correct, because clearance at full steering lock and during suspension movement can still change. Any RX350 that has been modified should be checked carefully for wheel diameter, wheel width, tire-to-fender clearance, and suspension travel before replacement tires are selected for regular road use.
What should I inspect before driving a 2009 Lexus Trucks RX350 on new tires?
Before driving a 2009 Lexus Trucks RX350 on new tires, inspect the wheel diameter, confirm the tire size matches the wheel, and check for proper inflation. It is also smart to look over the wheels themselves for damage and make sure there is no rubbing at the strut, fender liner, or steering components.
A short, careful road test is a good next step after installation. During that drive, pay attention to vibration, pulling, unusual noise, and any sign of interference during turning or over bumps, since those symptoms can point to wheel, alignment, or clearance issues that should be corrected before the vehicle is driven farther.
How often should tires on a 2009 Lexus Trucks RX350 be inspected?
Tires on a 2009 Lexus Trucks RX350 should be inspected regularly, not just when tread looks worn. Frequent visual checks for uneven wear, cracking, cuts, bulges, embedded objects, and air loss are especially important on a vehicle that may alternate between daily use and longer parked periods.
A routine inspection schedule helps catch problems before they become ride, handling, or safety issues. It also gives the owner a chance to verify that pressures remain correct and that the tires are wearing evenly across the tread, which can reveal alignment or suspension concerns before they shorten the service life of a replacement set.
