FYI - a Wrangler "expert" told me to deflate the Jeep tires to lessen the erratic ride - and it works. Tires call for 50 PSI and I have them at 30.
Regarding your tire inflation for towing......
Towing our Liberty with stock wheels and tires, I dealt with front tire thread damage caused from making sharp turns with the motor home. The Liberty tires follow along, but in sharp turns they skitch until the Liberty steering wheel catches up with the change in direction. It is especially bad making a sharp turn in one direction followed by an immediate sharp turn in the opposite direction. This is most commonly done in tight spaces like gas stations. The Liberty front tire thread damage is greatly reduced by having MORE air in the front tires. Also an aggressive tire is more easily damaged than standard street tires.
I assume the condition will worsen with non-stock, big tires with big offsets as many Wranglers are equipped with for off-roading. Hopefully people towing Wranglers will reply with applicable data.
The damage to the tires on our Liberty is not minor. Years ago I had installed a new set of Firestone Destination A/T tires on the Liberty. Before our vacation the tires were nice and quiet. After the trip, the tires were very noisy, and they got worse with every trip. Today I have street tires on the Liberty for trips and the tires are inflated for trips 4 psi more than recommended by Jeep. I have a second set of wheels and tires with a replacement set of Firestone Destination A/T tires for winter use around town. I won't put them on the Liberty for a vacation because they will get ruined.
adding since posting.....
Our problem is made worse because like most motor homes, ours has a significant overhang rear of the rear dual axle which creates the following scenario. When turning the motor home in one direction, it's large rear over hang swings out in the opposite direction, making our Liberty initially turn the wrong way, then cut sharp into the correct direction. It doesn't sound like a lot, but it is enough for me to actually see the phenomena occur in my RV rear view mirror.
I combat tire damage by over-inflating the front "street tires" to minimize tire-to-street contact resistance. Our aggressive A/T tires got beat up badly, but our street tires see minimal damage by comparison.
