My Jeep (JK) “Pizza Cutters” – Long Term Tire Review


After I got all of the useful life out of my original OEM “pizza cutters”, Goodyear Wrangler SR-A Radial Tire – 255/75R17 113S tires, which was every bit and a little more of the 60,000-mile tread life warranty, I decided to upgrade my pizza cutters.

At 61,932 miles on my JK, I replaced all (5) tires with the Toyo Tires Open Country A/T II 10 Ply Radial Tire-LT255/80R17 121R.

255/75R17 OEM “Pizza Cutters”

255/80R17 Toyo ATII “Pizza Cutters”

The 255/80R17 Toyo measures a true 33.1″, and does not require a wheel spacer!


Why a “Pizza Cutter” Tire?

Since 1941, every Jeep has had an inherent factory defect…tires that are too small in diameter and ESPECIALLY width!!!  Larger, specifically wider tires seem to be the craze, however, are wider tires REALLY necessary?

There are two schools of thought when it comes to skinny tires, “pizza cutters”, and wider tires:

(1) a skinnier tire will cut through to the solid surface, be it through rain/snow to the roadway, or through the mud to the solid ground to maintain forward momentum.

(2) wider tire to “float” in order to maintain forward momentum.  Obviously floating over a rain covered roadway is hydroplaning, and typically not desire-able, however floating through mud may at times, be more practical.

I am a skinny tire guy, look at the original Jeep, those were some skinny tires that got us through WWII!!!


The Toyo Tires Open Country A/T II 10 Ply Radial Tire-LT255/80R17 121R is a Light Truck, or LT, rated tire, and a bit on the heavier end, as Toyo Tires, seem to be.

Complete specs on the Toyo Tires Open Country A/T II 10 Ply Radial Tire-LT255/80R17 121R can be found within the chart/link below.

The Toyo Tires Open Country A/T II 10 Ply Radial Tire-LT255/80R17 121R new tread depth is 15.9/32″ new, with a 50,000-mile tread life warranty.

I was very pleased to have measured an average of 9/32″ left on my tires at 112,646 miles.

I have been very diligent about rotating my tires, including the spare, every 5,000 miles.

The Toyo Tires Open Country A/T II 10 Ply Radial Tire-LT255/80R17 121R has performed excellently in all-weather and terrain where I live in Michigan, with good wet weather and snow traction.

Off-road, the Toyo Tires Open Country A/T II 10 Ply Radial Tire-LT255/80R17 121R has also performed excellently on the trail, in the mud, and in the sand.


Upgrading to the Toyo Tires Open Country A/T II 10 Ply Radial Tire-LT255/80R17 121R pizza cutters has also improved my overall ground clearance, in addition to the more aggressive tread.

The Toyo Tires Open Country A/T II 10 Ply Radial Tire-LT255/80R17 121R are reasonably quite on-road, however do need to be balanced every two to three tire rotations.

Running a pizza cutter allows for a true 33″ tire that remains within the fender flares, keeping a lot of road debris and mud off the side of the Jeep.  Running a pizza cutter does not necessitate the use of the often controversial wheel spacers.

I did notice a slight decrease in highway performance, and a small difference in speedometer accuracy, due to the larger, and heavier tire.  Neither is enough to have to consider regearing or reflashing the speedometer.


Toyo Tires recently announced the All-New Open Country A/T III which looks like an even more aggressive A/T tread pattern.

I have been very satisfied with the performance of my Toyo Tires pizza cutters, and will seriously consider the Open Country A/T III for my next set of tires on my Jeep.


Pizza cutters may not be as cool as a big, fat and wide tire, however, they are a nice upgrade over stock, providing a small lift, yet a little more every day driving friendly!!!
