As automobile enthusiasts one of the first things we do by nature is simply look at our brand new high-tech vehicle and go hmmm, not good enough. Aftermarket wheels and tires are typically at the top of our list when comes to modifications. This guide should help to assist you in answering the question of the ages, how much tire can I fit without rubbing?
Before we jump immediately into the aftermarket sizes lets quickly cover sizes of wheels and tires as well as the other important metrics to consider when shopping for upgrades on your Tundra. Toyota offers many trim levels and each trim can receive additional packages that may alter the included tire/wheel size on the vehicle.
Bolt Pattern is standard at 6x139.7mm or 6x5.5in
Center Hub Bore is 95mm
Lug Nut Thread is M14x15
Available Factory Tire Sizes Include
245/75R18 all-season tires
265/70R18 all-season tires
265/60R20 all-season tires
265/50R22 all-season tires
265/70R18 Michelin® LTX Trail all-terrain tires (TRD Off-Road Package)
265/60R20 Falken® * WILDPEAK all-terrain tires (TRD Off-Road Package)
285/65R18 Falken® * WILDPEAK all-terrain tires (TRD PRO)
Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
Wheel Offset: When taking into account tire sizing and suspension height and particularly clearance from both body work and frames/body mounts wheel offset can play almost as big a role as the actual tire size itself. So what is wheel offset? Wheel offset is the distance from the hub mounting surface to the centerline of the wheel. The offset is measured in millimeters.
Offset is typically referenced in three different styles those being positive, negative, and zero.
Positive Offset: This is when the hub mounting surface is located in the front half of the wheel closer to the wheel face. This pulls the entire wheel in closer to the brakes and suspension of the vehicle. This is more common on factory wheel/tire combinations on non off-road trims/packages where fuel economy may be more the goal.
Negative Offset: With this style of offset there are varying degrees of how far the hub mounting surface is moved towards the back half of the wheel closer to the back lip. This will push the wheel farther away from the vehicle creating the dished look. This is a more common method of fitting wider/more aggressive wheel/tire packages on lifted trucks.
Zero Offset: Zero offset is when the hub mounting surface is even with the wheel centerline.
Stock Suspension
Now lets get into the first section of tire and wheel fitment. You want to just go up a small amount in size, just an inch to fit as much tire as you can without touching the stock suspension. For all Tundra trims/packages the stock tires will be in the 31.5-32.6" range.
Maximum Recommended Tire Size:
Any 33" Diameter Tire
2" Leveling Kit
This section will cover best tire/wheel combinations for use with just a leveling kit that requires a minimum investment to your suspension with the goal being to retain factory ride quality while providing just enough clearance for a larger tire/wheel package.
Maximum Tire/Wheel Size: 35x12.50R20 w/20x9 Wheel
(This is the maximum size without major rubbing)
Maximum Recommended Tire/Wheel Size:
(These sizes will have no rubbing)
17" Wheel and 33x12.50 Tire
18" Wheel and 305/65 Tire
20" Wheel and 305/55 Tire
22" Wheel and 33x12.50 Tire
Notes:
35" tire will fit with positive offset wheel (Slight trimming may be required)
33x12.50 tire will fit on 9" wide wheel w/+25mm offset (No rubbing)
3" Lift Kit
The next evolution of your Tundra might include a complete suspension system like a 3" Lift Kit. This more robust lift system whether it be an OEM Upgrade or Aftermarket provides both enhanced off-road capability as well as substantially more room in your wheel wells for a beefier wheel/tire package to call home.
Maximum Tire/Wheel Size: 37x12.50R18 w/18x8.5 Wheel +18mm/19mm Offset
(This tire size will require trimming of Front Air Dam, Front Fender Liner and Rear Fender Liner being pinned back, depending on wheel offset a body mount chop may be required to retain full turning radius without rubbing)
Maximum Recommended Tire/Wheel Size:
(These sizes will have NO RUBBING *pending proper offset*)
18" Wheel and 35x12.50 Tire +18mm/19mm Offset
20" Wheel and 295/60 Tire +18mm/19mm Offset
6" Lift Kit
The last portion of our tire/wheel fitment guide will cover those of you that when asked how much lift you wanted, your response was "YES". So here we are, 6" taller and ready for the largest wheel and tire packages available. At this point you're pretty much at the discretion of your wallet.
Maximum Recommended Tire/Wheel Size:
20" Wheel and 37x12.50 Tire +18mm-20mm Offset
(This tire size will require trimming of Front Air Dam, Front Fender Liner and Rear Fender Liner being pinned back, depending on wheel offset a body mount chop may be required to retain full turning radius without rubbing)
20" Wheel and 35x12.50 Tire +18mm-20mm Offset
Note: Lift dependent check, may allow for up to 5.5" backspace on 20x9 wheels with 37" tires and still retain full turning radius.
