Winter to summer tires. T1XX AT4 wheels on K2XX

Recommended Posts

I picked up a set of AT4 wheels and tires. I like the look of them but this set came with the smallish 265/65/18 Goodyear Fortitude HT tires. They’ll be fine for all the summer driving and can save some wear on my 285/70/17 BFG K02. 

Noticed an immediate weight difference. Fortitude weighs 56 lbs mounted on 18” wheel. BFG k02 Load Range E weighs 81 lbs on 17” wheel.

I'm doing the same thing, took the Fortitudes off and put on Dura Traks. Noticed a 4-5 mpg decrease with the Dura Traks on my 3.0. Got a set of take off wheels coming next week and am going to mount the Fortitudes on them and run them for the summer. Shouldn't have to buy any tires for quite a long time.?

Watch out for Chinese counterfeit TPMS sensors all over eBay and amazon. They are even printing counterfeit factory looking acdelco bags and boxes. I found lots of “genuine oem” sensors with a star on one side of sensor which is not oem. 

factory sensors are made in Mexico or uk and have a 3C on one side. 

I found a set on eBay that were removed from oem wheels for $30 shipped set of 4. 

check your build sheet or glovebox to see if your truck is 315 or 433 MHz. I believe 315 is much more common on 2007.5 - 2018
