The 2006 Toyota Trucks 4Runner sits in the era when SUVs were expected to balance daily-road comfort with genuine trail capability, and that broad-purpose character still shapes tire selection today. Whether kept as a dependable family 4Runner or used for weekend dirt and gravel, the wheel and tire package makes a real difference in stance, ride, and clearance. This model uses three primary radial sizes: 265/60R18, 265/65R17, and 265/70R16, depending on sub-model. The main decision is not bias-ply versus radial, but identifying the correct wheel diameter first and then matching the tire to the vehicle's trim, intended use, and current wheel setup.
Which Tire Size Is Right for The 2006 Toyota Trucks 4Runner
The 2006 Toyota Trucks 4Runner uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. All three are metric radial sizes with very similar overall diameters, but they fit different 16-inch, 17-inch, or 18-inch wheel setups. Before choosing a tire, confirm whether the vehicle is a Limited, Sport, or SR5, and verify that the wheels currently on the truck match the intended size.
A 265/60R18 tire uses a 265-millimeter nominal section width, a 60-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2006 Toyota Trucks 4Runner, this size is tied to the larger 18-inch wheel setup rather than the 16-inch or 17-inch configurations used elsewhere in the range. Its metric radial format is familiar to modern SUV owners and keeps sizing easy to compare when replacing worn tires. This is the size to focus on when the vehicle is a Limited model or when the truck already carries factory-type 18-inch wheels.
A 265/65R17 tire combines a 265-millimeter section width with a 65-series profile and radial construction for use on a 17-inch wheel. This size appears on the 2006 Toyota Trucks 4Runner in trims that use the mid-range wheel diameter, making it a key fitment to separate from the 16-inch and 18-inch alternatives. It is a practical modern SUV size for buyers who want to stay with the established wheel package on the truck. Choosing it starts with confirming the current 17-inch wheel setup, especially if the vehicle has seen previous wheel or tire changes.
A 265/70R16 tire carries the same 265-millimeter nominal width as the other 4Runner sizes here, but pairs it with a 70-series profile on a 16-inch rim. For the 2006 Toyota Trucks 4Runner, this size belongs to certain SR5 configurations and should not be assumed across every trim. Available product choice in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls, an all-terrain series, and a 7.0- to 8.5-inch rim-width range. It is the size to evaluate when the truck has the 16-inch wheel package and a more rugged tire presentation is part of the goal.
Tire fitment on the 2006 Toyota Trucks 4Runner varies by sub-model, so identifying the exact trim matters before comparing tire options. The main dividing point is wheel diameter, since Limited, Sport, and SR5 configurations do not all use the same size.

2006 Toyota Trucks 4Runner Limited
The 2006 Toyota Trucks 4Runner Limited uses the 265/60R18 radial size, which places it on the 18-inch wheel setup rather than the smaller wheel packages used on other trims. Tire selection starts with confirming that the vehicle still has the correct 18-inch wheels before comparing replacement options.
The 2006 Toyota Trucks 4Runner SR5 can use either 265/65R17 or 265/70R16, making it the trim where wheel verification is especially important. Before selecting a tire, check whether the truck has the 17-inch or 16-inch setup so the replacement matches the actual wheels on the vehicle.
The 2006 Toyota Trucks 4Runner Sport uses the 265/65R17 radial size on a 17-inch wheel. That keeps tire selection more straightforward than the SR5, but it is still worth confirming the current wheel diameter if the truck has ever been modified or fitted with aftermarket wheels.
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 2006 Toyota Trucks 4Runner?
The 2006 Toyota Trucks 4Runner uses three primary tire sizes: 265/60R18, 265/65R17, and 265/70R16. Limited models use 265/60R18, Sport models use 265/65R17, and SR5 models may use either 265/65R17 or 265/70R16 depending on wheel setup.
The key step is matching the tire size to the actual wheels on the truck, not just the model name on the badge. Many 4Runners have seen wheel changes over time, so it is smart to confirm the current rim diameter before ordering tires. The three sizes are close in overall diameter, but each one is intended for a different wheel size.
What size rim does a 2006 Toyota Trucks 4Runner use?
A 2006 Toyota Trucks 4Runner can use 16-inch, 17-inch, or 18-inch rims depending on sub-model. The 265/70R16 size fits a 16-inch rim, 265/65R17 fits a 17-inch rim, and 265/60R18 fits an 18-inch rim.
Rim diameter is the first fitment detail to verify because the tire must match the wheel exactly. A truck with replacement wheels may no longer match its original trim-based setup, especially on SR5 models that could be equipped with more than one size. Checking the wheel itself prevents choosing a tire that matches the badge but not the actual hardware on the vehicle.
Why does the 2006 Toyota Trucks 4Runner have more than one tire size?
The 2006 Toyota Trucks 4Runner has more than one tire size because tire fitment changes across the Limited, Sport, and SR5 sub-models. The difference is tied mainly to wheel diameter, with the model range using 16-inch, 17-inch, and 18-inch wheel packages.
That means the right tire is determined by the specific trim and the wheels currently on the truck, not by year and model alone. SR5 fitment especially deserves a closer look because it appears with both 16-inch and 17-inch tire sizes. Confirming the sub-model and wheel diameter first keeps the selection process simple and avoids a mismatch.
Choosing the Right Tire
What should I consider when choosing a 265/70R16 tire for a 2006 Toyota Trucks 4Runner?
Start by confirming that the 2006 Toyota Trucks 4Runner actually uses the 265/70R16 size, since that fitment applies to certain SR5 configurations rather than the full model range. Once the size is confirmed, compare construction, intended use, sidewall style, and rim-width compatibility within the available products.
A 265/70R16 all-terrain tire can suit an owner who wants a more rugged look and broader trail-oriented use, but wheel compatibility still matters. The available BFGoodrich option in this size fits a 16-inch rim with a 7.0- to 8.5-inch width range. It is also worth checking load capacity, current suspension condition, and clearance if the truck has non-stock wheels.
What sidewall styles are available for 2006 Toyota Trucks 4Runner tires?
Among the currently available products for the 2006 Toyota Trucks 4Runner, the visible sidewall style is RWL, or raised white letter, in 265/70R16. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 option for certain SR5 applications.
Sidewall style mainly affects appearance, but it can also help signal the kind of tire you are selecting. Raised white letters tend to suit a more traditional truck presentation than a plain black sidewall. Appearance should still come after fitment, so confirm the truck uses the 16-inch SR5 wheel package before choosing a tire based on sidewall styling alone.
What brands offer tires for the 2006 Toyota Trucks 4Runner?
Current product coverage for the 2006 Toyota Trucks 4Runner includes BFGoodrich in the 265/70R16 size. The available tire is the BFGoodrich All-Terrain T/A KO2, a radial all-terrain design with raised white letter sidewalls.
Brand is only one part of the decision, especially on a model with several different original wheel diameters. Before focusing on tread style or appearance, make sure the truck uses the 16-inch wheel setup that matches this product. After that, compare the tire's series character, rim-width range, load capacity, and whether its more aggressive presentation suits how the 4Runner is driven.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Toyota Trucks 4Runner?
A period-style tire choice for a 2006 Toyota Trucks 4Runner starts with using the correct trim-specific size: 265/60R18 for Limited, 265/65R17 for Sport, or 265/65R17 or 265/70R16 for SR5. Staying with the proper wheel diameter does more for an authentic overall look than chasing an aggressive tread pattern first.
Appearance choices should reflect how the truck is being preserved or presented. A raised white letter all-terrain can give an SR5 a more traditional SUV or light-truck look, but it should not be assumed across every trim. Owners focused on exact originality should compare tire choice against original sales literature, factory documentation, or marque-specific reference material before making a final decision.
Does correct tire fitment matter for a 2006 Toyota Trucks 4Runner restoration?
Correct tire fitment matters on a 2006 Toyota Trucks 4Runner restoration because the truck was offered with more than one wheel and tire combination. Using the right size for the sub-model helps preserve the intended stance, wheel-to-tire proportion, and overall presentation.
The biggest restoration mistake is often choosing a tire only by approximate diameter while overlooking the actual wheel package. Limited, Sport, and SR5 trims do not all share the same setup, and SR5 fitment can vary even within the trim. Verifying rim diameter first keeps the restoration visually consistent and avoids the mismatched look that comes from using the wrong profile on the wrong wheel.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Toyota Trucks 4Runner?
Yes, modifications can affect tire fitment on a 2006 Toyota Trucks 4Runner even when the tire size looks close to stock. Aftermarket wheels, suspension lifts, lowering changes, altered offsets, and fender modifications can all change how a 265/60R18, 265/65R17, or 265/70R16 tire sits on the vehicle.
The safest approach is to confirm the actual wheel diameter and width already on the truck, then check clearance at full steering lock and through suspension travel. A 4Runner that has been changed from its original setup may need more than a basic trim-level tire lookup. Paying attention to clearance and wheel specs helps prevent rubbing, uneven wear, and avoidable fitment surprises.
What should I inspect before driving a 2006 Toyota Trucks 4Runner on new tires?
Before driving a 2006 Toyota Trucks 4Runner on new tires, inspect wheel condition, lug hardware, valve stems, and inflation pressure, then confirm that the tire size matches the wheel diameter on the truck. It is also smart to look over the suspension and steering components if the vehicle has been sitting or is being returned to regular use.
A road test should include listening for rubbing, vibration, or pull once the tires are installed. Older SUVs can hide worn shocks, bushings, or alignment issues that become more obvious with fresh tires. Checking pressure regularly during the first several drives, along with a quick visual look at sidewalls and tread, helps catch small problems before they become larger ones.
What should I check before a longer drive in a 2006 Toyota Trucks 4Runner?
Before a longer drive in a 2006 Toyota Trucks 4Runner, confirm correct inflation, inspect tread and sidewalls for cuts or bulges, and make sure the tire size on the truck matches its actual wheel diameter. A quick look for uneven wear can also reveal alignment or suspension issues that deserve attention before highway use.
Longer trips put more heat and continuous load into the tires, so condition matters as much as tread depth. It helps to check for slow air loss, verify that the spare is serviceable, and inspect the wheels for damage around the bead area. On a collector-use or lightly driven 4Runner, tire age and storage history can matter even when mileage is low.
