On my previous 4Runner, which I purchased new as well, I left the factory tires on until they wore out which occured at
approximately 45,000 miles. At that time I upgraded to Revos. The upgrade was significant enough for me to want to do
this on my 2007 4Runner within the first month of receiving the vehicle. The Revo tires offer much better traction in wet
weather, in the snow and off road, are a larger size and have a better look all without increasing the highway driving
noise level nor make the vehicle have a harsh ride. No sense waiting years for the factory tires to wear out.
By doing this mod even before finishing the first tank of gas, enabled me to sell the factory tires while in like
new condition and receive maximum value for them.
As mentioned earlier I went with the standard load rating, otherwise known as "P Metric". The Revos are available in
"E" load rating which I would recommend if you do alot of off-road driving. The E load Revos are stiffer (3 side wall
plys rather than 2), heavier (6 pounds heavier each), have deeper tread (3/32 deeper), are wider (4/10" wider) and more
expensive ($20 more per tire). None of those items I desired for the type of driving that I primarily do.

The Dueler A/T REVO with UNI-T AQII Technology was developed to meet the needs of pickup truck and
sport utility vehicle drivers who drive their vehicle both on and off the road.
The Dueler A/T REVO is Bridgestone's first Off-Road All-Terrain light truck tire in America to
feature UNI-T AQII Technology. It uses an advanced compound and construction features that enhance and
preserve wet traction throughout the tire's life to better handle wet road conditions.
On the outside, the Dueler A/T REVO molds a Super Long Link Carbon Black, Dual Layer Tread II compound
into an aggressive, all-terrain pattern of interlocking tread blocks to provide traction and handling
on- and off-road. As the top layer of tread compound wears away, it reveals a second layer specifically
developed to resist aging and remain pliable to retain more wet traction-even as it wears.
Internally, the Dueler A/T REVO features a Computer Optimized Component System that blends twin high
strength steel belts reinforced with spirally wrapped nylon to stabilize the tread area and enhance
durability while minimizing weight. O-Beads (which use a single strand of bead wire that is continuously
wrapped multiple times until the desired strength is provided) enhance the tire's fit to the wheel to
improve uniformity and ride quality.
The R- or S-speed rated Bridgestone Dueler A/T REVO tires feature outline white letter sidewall
styling on one sidewall and stylized black letter styling on the other. They are available in popular
P-metric, LT-metric and Flotation light truck sizes for 15" thru 17" wheel diameters.

Rotation Pattern
Five Tire Rotation Pattern:
The 4th generation 4Runner comes equipped with a full size spare tire mounted on a matching full size aluminum alloy wheel.
I have upgraded the spare tire as well to a 32" Bridgestone A/T Revo tire.
The one inch larger than factory P265/70/R17 tire does fit in the stock spare location.
A Five tire rotation pattern results in equally distributed use that will help maintain equivalent tread depths
on all five tires throughout their life. When applied to the 4Runners full time four wheel drive system
(all wheel drive is standard with the V-8 engine option), this will prevent driveline damage if a flat tire forces
a spare to be put into service with partially worn tires on the other three wheel positions.
By rotating the spare into the pattern, you accomplish a secondard benefit of extending the other tires life a little
longer and getting useage out of the spare. Remember, tires have a shelf life and do dry out after many years.
You may as well get some use out of the spare rather than discarding it unused when your main four tires wear out.
I have chosen to rotate my tires every 5,000 miles using the pattern shown below.
The spare will be inserted in the passenger side rear position at each rotation.
Place the tire that would have gone to the right rear in the spare location until the next tire rotation.
