2009 Lexus Trucks Tire Fitment Guide

2009 Lexus Trucks vehicles use four different tire sizes across three models. The GX470 uses 265/65R17, the LX570 uses 285/50R20, and the RX350 uses either 225/65R17 or 235/55R18 depending on wheel package. Those sizes do not share one common rim diameter, since the range includes 17-inch, 18-inch, and 20-inch wheels. For the one size with detailed wheel information here, 225/65R17 works with a 17-inch rim and a 6.0- to 8.0-inch rim-width range.

That means year and make alone are not enough to choose tires for 2009 Lexus Trucks. GX470 and LX570 owners need the correct model-specific size, while RX350 owners need to verify whether their crossover carries 17-inch or 18-inch wheels before moving any further. Checking the sidewall on the current tire or confirming the wheel diameter directly is the quickest way to avoid ordering the wrong fitment.

On a 2009 Lexus Trucks tire, 265/65R17 is a metric radial size. The 265 is the tire's section width in millimeters, 65 is the aspect ratio, meaning the sidewall height is 65 percent of that width, R identifies radial construction, and 17 is the wheel diameter in inches. Within the 2009 Lexus Trucks range, this size belongs to the GX470.

Understanding that code helps you separate wheel diameter from tire width and profile. A 265/65R17 cannot replace an 18-inch or 20-inch fitment simply because the vehicle is another 2009 Lexus model. If you own a GX470, this code gives you the correct format to match when comparing replacement tires, but the final choice should still be checked against the actual wheel and the intended driving use.

No, 2009 Lexus Trucks models do not use the same tire size. The GX470 uses 265/65R17, the LX570 uses 285/50R20, and the RX350 uses either 225/65R17 or 235/55R18. Even though all of them use radial construction, the wheel diameters and section widths differ from model to model, so the fitment is not interchangeable across the lineup.

That difference reflects how varied the 2009 Lexus utility range was, from a mid-size truck-based SUV to a full-size flagship SUV and a road-oriented crossover. The practical takeaway is simple: identify the exact model first, then verify wheel diameter, especially on the RX350. Once that is confirmed, you can narrow your search to the correct size rather than trying to compare every Lexus truck and crossover tire from that model year.

Among 2009 Lexus Trucks tire options shown here, the 225/65R17 size is available with an RBL sidewall from BFGoodrich. RBL means raised black letters, a style often chosen when an owner wants a more rugged or truck-oriented look instead of a plain blackwall appearance. The other 2009 Lexus Trucks sizes use radial construction as well, but sidewall style details depend on the specific product in those sizes.

Sidewall appearance matters more than many buyers expect, especially on luxury SUVs where the visual balance between wheel, tire, and body style is part of the vehicle's character. An RX350 with a more road-focused look may call for a different visual approach than a GX470 used for trail or utility duty. Choosing sidewall style after confirming the exact size keeps appearance and fitment decisions in the right order.

BFGoodrich is represented in 2009 Lexus Trucks fitment here through the 225/65R17 size used on certain RX350 applications. That tire is the All-Terrain T/A KO2, a radial design with an S speed rating and an RBL sidewall. Other 2009 Lexus Trucks sizes also use radial construction, but brand choice depends on the exact size and model you are matching.

Brand selection should follow fitment confirmation, not the other way around. A GX470 owner, LX570 owner, and RX350 owner are not shopping from the same size pool, so the right approach is to start with the size stamped on the vehicle's existing tires or wheels and then compare available brands within that size. That avoids confusing model identity with tire identity, which is a common problem on year-make searches.

For a 2009 Lexus Trucks RX350 in 225/65R17, the BFGoodrich All-Terrain T/A KO2 is a radial tire with an RBL sidewall, a 107S service description, a 2,150-pound maximum load at 65 psi, and a 39-pound tire weight. Its size fits the 17-inch RX350 application, and its naming and construction point toward a more utility-oriented character than a typical crossover street tire. That makes it a distinct choice within the RX350's fitment range.

The practical question is how you use the vehicle. An RX350 that stays on pavement and is being preserved in a more original luxury-crossover style may call for a different tread personality than one that sees rough roads, weather, or occasional unpaved travel. Fitment still comes first, but after that, the tire's overall character should match the way the RX350 is actually driven rather than the way it is remembered.

Rim-width guidance for 2009 Lexus Trucks is available here for the 225/65R17 size used on certain RX350 applications. That size fits a 17-inch wheel and works with a 6.0- to 8.0-inch rim-width range. The other 2009 Lexus Trucks sizes also have their own wheel-diameter requirements—17 inches for 265/65R17, 18 inches for 235/55R18, and 20 inches for 285/50R20—even where a rim-width range is not stated here.

Rim width matters because two wheels can share the same diameter but still be wrong for the tire if width is outside the approved range. If you are working with an RX350 on 225/65R17, that 6.0- to 8.0-inch window is the key checkpoint. For the other sizes, confirm the actual wheel dimensions before mounting, especially if the vehicle has aftermarket wheels or has changed hands several times.

The available 225/65R17 tire for 2009 Lexus Trucks does not show a tube-type marking, which is consistent with modern tubeless radial construction. That fits the expectations of a 2009 Lexus product, where tubeless radial tires are the normal setup rather than tube-type fitments common to much older vehicles. Tube requirements for other 2009 Lexus Trucks sizes should still be confirmed on the specific tire and wheel combination being used.

The important point is to match the tire's construction and marking to the wheel it will be mounted on. A modern Lexus wheel is generally intended for tubeless use, but you should still inspect the wheel condition, valve stems, and bead seat before mounting replacement tires. If a product carries a special marking or the wheel has been altered, that should be sorted out before the tire goes into service.

A 2009 Lexus Trucks vehicle should be stored clean, dry, and out of direct sunlight, with the tires kept away from electric motors, battery chargers, welders, and other ozone sources that accelerate rubber aging. Inflate the tires to the vehicle's normal storage pressure, keep the vehicle off damp soil, and roll it periodically if it will sit for long stretches. Modern radial tires resist temporary flat spotting better than older bias-ply designs, but long static storage still works against tire shape and sidewall condition.

If the vehicle will be parked for a season or longer, many collectors use tire cradles or place the vehicle on stands to reduce constant load on one footprint. That is especially useful on heavier models like the LX570, where curb weight puts more continuous stress on the tires during storage. A simple storage routine can preserve ride quality and sidewall appearance far better than trying to correct damage after the fact.

Tires on a 2009 Lexus Trucks vehicle should be judged more by age and condition than by mileage alone, especially on lightly driven luxury SUVs and crossovers. A good rule is to begin careful age evaluation around five to seven years and to treat ten years as the point where replacement deserves serious consideration regardless of tread depth. The DOT date code on the sidewall tells you when the tire was made, which is often more important than how fresh the tread looks.

Collector and low-mileage vehicles can fool owners into thinking a deep-tread tire is still serviceable simply because it has not been worn out. In reality, the rubber compound, casing, and internal structure age every year whether the vehicle is driven often or not. If your 2009 Lexus Trucks vehicle still carries an older set, have the tires evaluated before a long trip rather than assuming low miles mean long remaining life.

Tires on a 2009 Lexus Trucks vehicle should be inspected before every drive and given a more thorough check before any extended trip. Look for cracking, cuts, bulges, uneven wear, punctures, and any sign that the tire is losing pressure over time. On a modern radial SUV tire, shoulder wear or one-sided tread wear can also point to alignment or suspension issues rather than a tire problem alone.

A quick walk-around catches more problems than many owners expect, especially on vehicles that spend long periods parked. Pressures should be checked cold, and any tire that looks aged, damaged, or oddly worn deserves closer attention before the vehicle is taken onto the highway. If the vehicle has a spare, inspect that tire as well, since a neglected spare often becomes unusable at exactly the moment it is needed.

Yes, 2009 Lexus Trucks tires can be suitable for highway driving when the correct size is used, the tires are in sound condition, and the service rating matches the intended use. The 225/65R17 BFGoodrich tire available here carries an S speed rating, which corresponds to a 112 mph ceiling. That is well above normal U.S. highway speeds, although safe road use still depends heavily on the vehicle's condition, tire age, inflation, and load rather than on speed rating alone.

For a modern Lexus SUV or crossover, the larger concern is usually maintenance discipline rather than whether the basic radial construction can handle everyday highway use. An aging tire, poor alignment, old shocks, or underinflation can turn a capable fitment into a bad driving experience. Before any longer highway run, inspect the tires carefully and make sure the vehicle's brakes, steering, and suspension are up to the same standard as the tires.

Inflation pressure for 2009 Lexus Trucks tires should start with the factory vehicle recommendation for the exact model and wheel package, then be checked against the tire's own service information. For the available 225/65R17 tire, the maximum load figure is 2,150 pounds at 65 psi, but that is a maximum-rated value rather than a blanket setting for every RX350. The GX470, LX570, and the 18-inch RX350 fitment should each be matched to their own model-specific inflation guidance.

Using one pressure across every 2009 Lexus Trucks model is the wrong approach because the sizes, wheel diameters, and vehicle weights differ. The best practice is to use the placard or owner's manual as the baseline for normal road use, then confirm that the chosen tire is being operated within its own load and pressure limits. If the vehicle is carrying unusual cargo or towing, pressure should be reviewed with that use in mind.

Before taking a 2009 Lexus Trucks vehicle on a longer drive, inspect every tire for cracking, cuts, bulges, punctures, uneven wear, and correct cold inflation. Check the valve stems, confirm tread depth is even across the axle, and make sure the spare is present and serviceable. On vehicles like the RX350, also verify that the tire size matches the wheel package, since a 17-inch fitment and an 18-inch fitment are not interchangeable.

That tire check should be part of a wider pre-trip inspection on any older used luxury SUV, even one that feels modern by collector standards. Fluids, brakes, battery condition, and suspension components all influence how the vehicle behaves on the road once speeds rise and trip length increases. Tires are only one part of the equation, but they are the part touching the road, so they deserve attention first.
