About 6 weeks ago we purchased our first Jeep, a 2018 JL Jeep Wrangler Unlimited. The dealership already had a lift and larger tires installed on it. Tires are BF Goodrich All-Terrain T/A KO2 35x12.5R18LT Load Range E. They had the air pressure set at 42.
When driving the Jeep on the highway/interstate it wandered all over the road. I figured it had to be because of the air pressure, but didn’t have a clue of how much lower I should go. I talked with a few people and everyone that had the same tires was using different air pressure, from 30-32, 34-36, and 40-42. I finally sent wayoflife a PM, and he was able to provide me with a good starting point.
I started with 30, went to 32, then 34, and back down to 28. I ended up going back to 30. So far we have 2600 miles on our Jeep. It rides much better than it did when we purchased it, and no longer wanders all over the road. I think it would be a great help to others if a lot of us posted what tires were on our Jeep, and what air pressure we were using.
Also purchased a TazerJL so I could change the settings for TPMS, along with some of the other features. Great device, well worth the money.
Thanks again Eddie for your help!
