The Toyota 4Runner TRD Pro is the off-road flagship of the 4Runner lineup: Multi-Terrain Select, KDSS suspension, front skid plates, and a factory lift. Uniquely, the TRD Pro ships with BF Goodrich KO2 all-terrain tires from the factory, one of the few mainstream production trucks or SUVs to include the KO2 as OEM. That means the TRD Pro already starts with one of the best A/T tires available, which raises the question of whether upgrades are truly necessary.
TRD Pro Tire Fitment
The Toyota 4Runner TRD Pro ships on 265/70R17 BF Goodrich KO2 all-terrain tires on 17-inch TRD Pro-specific wheels. The 265/70R17 measures approximately 31.6 inches tall, providing a meaningful lift in appearance and off-road clearance compared to standard 4Runner trims at 265/65R17.
The standard 4Runner SR5 and TRD Off-Road also use 265/70R17, though not the KO2 tire — that specific KO2 fitment is exclusive to the TRD Pro. TRD Sport and Limited step down to 245/60R20 on 20-inch wheels.
The 265/70R17 size has strong aftermarket availability. It's a common mid-truck all-terrain size used by Toyota Tacoma, 4Runner, and Land Cruiser owners worldwide.
When to Upgrade From OEM KO2 on the TRD Pro
The BF Goodrich KO2 is already an excellent tire. The honest answer is: if you are happy with the KO2's performance, replacing it with another KO2 set when worn is a valid choice. The TRD Pro comes with a top-tier tire for a reason.
When to consider upgrading: for aggressive rock crawling or sustained deep mud use, a mud-terrain tire (BF Goodrich KM3, Falken Wildpeak MT01, Nitto Trail Grappler) offers more aggressive tread blocks and better self-cleaning. The KO2 is an excellent A/T but is not a dedicated mud tire.
For overland-focused TRD Pro owners: the Cooper Discoverer AT3 XLT in Load Range E is a strong alternative to the KO2 that some owners prefer for its on-road noise profile and LRE construction for heavy loaded travel.
For winter use: the KO2 carries 3PMSF winter certification and is the TRD Pro's factory choice for a reason. It handles Georgia's rare winter conditions, wet roads, and occasional light snow well. No winter tire swap is necessary in most Georgia climates.
Frequently asked
What tires does the Toyota 4Runner TRD Pro come with?
The TRD Pro ships with BF Goodrich KO2 all-terrain tires in 265/70R17 on TRD Pro-specific wheels. This is the factory choice, one of the few mainstream production vehicles to include KO2 from the factory.
What size tires does the 4Runner TRD Pro use?
265/70R17 (approximately 31.6 inches) with the KO2 tire — a fitment exclusive to the TRD Pro trim, though SR5 and TRD Off-Road share the same 265/70R17 size with a different OEM tire. TRD Sport and Limited use 245/60R20 on 20-inch wheels. The 265/70R17 adds ground clearance and visual presence without requiring a suspension lift.
Can I put 33-inch tires on a 4Runner TRD Pro?
True 33-inch tires (like 285/70R17 at approximately 32.7 inches, or 275/70R18 at 33 inches) are close to the 265/70R17 OEM size. Minor contact may occur at full suspension droop with 33-inch tires — many TRD Pro owners run 285/70R17 successfully with just a minor spacer adjustment. Verify with a TRD Pro-specific fitment guide before purchasing.
Is the BF Goodrich KO2 the best tire for the 4Runner TRD Pro?
For most use cases, yes. The KO2 is a proven choice for the TRD Pro platform. It balances on-road manners, off-road capability, and 3PMSF winter certification well. For aggressive rock crawling or deep mud use, a dedicated M/T like the BF Goodrich KM3 offers more grip in extreme terrain. For purely on-road driving with light trails, the KO2 is the right call.
