All of the Lambda platform GM vehicles above come stock with, or have been optioned to have, the 255/65R18 tire size. Did you know that a 265/60R18 works just as well, and gives you some great alternate tires to consider? Take a look at a few of the options listed below:
The Lambda platform crossovers can be frustrating to purchase new tires for if you don't want to pursue the tires GM supplies as Original Equipment. All of the tires on the above list offer a quiet ride, all-season performance, good wet grip and excellent handling for your crossover.
As always, be sure to check the tire size your vehicle has before shopping. Some of these vehicles have 17" and 20" wheel options depending on the trim level.

The Bridgestone Potenza RE970AS Pole Position finished at the top of our most recent test of Ultra High Performance All-Season tires. This test evaluated the leading tires in the category on the road and on wet and dry test track conditions.
Potenza RE907AS Pole Position tires mold a new all-season rubber compound into a directional tread design that combines responsiveness on dry roads, with traction in wet and wintry driving conditions. A series of circumferential and lateral grooves help pump water and slush through the tire's footprint to enhance hydroplaning resistance, wet road and light snow traction.
A good all-season tire must offer the following qualities:
-
Well-rounded
-
Balance wet, dry and snow capabilities
-
Good ride comfort
-
Sporty handling
-
Longevity
This broad set of parameters can make it difficult for a tire to excel in any one area. The RE970AS Pole Position does an excellent job of balancing all of the competing demands that a tire of this category needs to meet. To see how the tire performed in our tests last summer, read "Testing Bridgestone's Potenza RE970AS Pole Position Ultra High Performance All-Season Tire."
The one thing that our test did not measure was snow traction. We did take customer survey results that included evaluations for snow traction from the past winter and the results have again been favorable. With data from over 417,000 miles, the RE970AS is currently at the top of our Tire Survey Results.
For over a decade, the Honda Odyssey has been one of America's top selling minivans. With its good looks, spacious interior and Honda's reliability, the Odyssey has logged millions of miles on U.S. roads. Along for the ride are some very good choices of tires, including the most common size of 235/65R16.
Having spoken with hundreds of Odyssey owners and having made several more recommendations, I've found three tires that have been solid choices.
My favorite option is the Goodyear Assurance ComforTred Touring. This tire is one on the best riding tires I have ever driven on. Period. It offers the qualities most drivers are looking for in a tire: very smooth, quiet, great all-season traction and will last a long time.
Next, the Continental CrossContact LX20 with EcoPlus Technology is an ecologically friendly tire that's designed to enhance driving pleasure, save fuel and maintain grip while on wet surfaces. Technically, the tire is marketed as a Crossover/SUV Touring All-Season tire, but works just as well on the Honda Odyssey. This tire is also very comfortable and offers excellent traction. The difference with this tire is its low rolling resistance technology that provides drivers with a little better fuel economy.
When in comes to a value option, I prefer the Hankook Optimo H727. This tire offers good all-season traction and reasonable ride manners. It's developed to deliver a premium appearance and long wear along with dry, wet and wintertime traction, even in light snow. Optimo H727 tires also come with a 100,000-mile treadlife warranty.

Michelin's new Defender aims to replace two of Michelin's most successful tires: the Harmony and HydroEdge with Green X. The Harmony, as its name describes, has long been one of the most comfortable and quietest tires offered. And the HydroEdge with Green X is one of the most successful tires in the Michelin line-up for its wet traction and long treadwear.
Michelin sought to combine the success of each of these tires into one complete package. Defender tires offer the smooth, quiet ride and proven winter traction of the Harmony with the 90,000-mile treadlife warranty and superior wet traction of the HydroEdge with Green X. This tire also meets Michelin's Green X objectives, which provides less rolling resistance and saves you money on fuel cost.
When compared to the Harmony, the Defender offers 22% better rolling resistance and 16% shorter wet braking. And compared to the HydroEdge with Green X, the tire provides 10% lower noise along with 15% better snow performance. Defender tires feature IntelliSipe Technology that increases the number of sipes in the tire's tread design to provide additional biting edges that enhance all-season traction in rain and snow.
IntelliSipe Technology enhances performance in three ways:
-
Helps stabilize the tread block during acceleration, braking and cornering.
-
Increases the number of sipes on the tread, which results in greater grip for confident braking.
-
Interlocking action that creates a more rigid tread block and reduces tread depth without sacrificing longevity or fuel efficiency.
