You do have to remember with tires and weight, that rotational weight has a bigger effect on performance than static weight. If you sat a 100 lb weight in the Jeep, it would not have that much of an effect on the acceleration. But if you strapped the 100 lbs on the rims or tires, the weight would have a mulitplied effect, because the engine would have to work harder to turn the wheels. There are dozens of other factors involved in the tire size equation, friction, drag, tire pressure, etc... I agree with the other posters that other parts will have problems before the 3.8L does with huge tires.

just got to regear it to 5.13 and then you will be able to run what ever you want. Also depends on your lift height (if you have one even), make sure the JK can clear the tires without rubbing. It the not the engine that make stop people from going to bigger tires, it the gears. Hope this helps!!

It's also while you're only supposed to have 100lbs of tongue weight. Now 3500lbs might be nearing what Jeep believes the engine is capable of towing safely but if you throw 3500lbs on the 2 door and jump on the brakes at 60 mph you've got a pretty good chance of doing a wheelie and that would be youtube worthy... I believe there is a guy on here with the four door and a special hitch towing a 5500lbs trailer. I'm not saying it'd be fun but it works. Gears are your friend.
