Following my own recommended goal of 3000rpm at 75mph(120kph), the ideal tire size for the 42rle and 4.56 would be about a 26" tire.

Okay i understand. I check my jeep every week, and i choose best parts (i replace all the old parts). But It’s not a problem for me to drive slower and don’t drive more 70, i prefer security to problems, i don’t buy a jeep to go quick, just enjoy the moment. My question is : 33s on my actually wheel(15x10) will be okay (not perfect) ? Or is it better to stay and not save money and buy new wheels(15x8) + tires 31-32 ?

Diff dragger!
I will say again, driving high speed (70+) in a TJ jeep is asking for trouble. Slow down, they are not a sports car.
My TJ drives comfortably at 80mph.
It’s my first publication, my english is not perfect.
So do I. Two fingers minimum on the wheel for safety. I drove my old Jeep on 35s to the Florida Keys (16 hours one way) and I only slowed down to 85 when I saw cops.
To be honest, if my jeep wasnt completely stable at 80, I wouldn't be comfortable driving it much over 30. In my opinion, either the vehicle is set up to work on highways or it isn't.
Nothing down stream of the transfer case, and south of the frame is more than 5 years old, all the parts on it are premium quality, way over built, and as finely aligned and balanced as my local shop can get it. Sure, she's brick shaped, so the wind catches her like a sail and so I keep my whole hands on the wheel, but it feels sure footed enough that I see no reason it wouldn't go all the way up to the tires speed rating of 99mph.
All of that being said, I find the most comfort and economy at 55-60. If I'm wanting to make time at the expense of noise and fuel, 75 is not a big sacrifice (in noise anyway).
I agree. If you want a 81+ mph vehicle, I don't believe you want a Jeep TJ. There are no aerodynamics with a TJ. It is basically a box on wheels. Sure, one can add a supercharger or a Hemi to a Jeep, but then again, I think you have the wrong vehicle. Just stay in the slow lane around 70, stay safe, and enjoy its off road capabilites. I can drive 81+ mph in my maintained stock 4.0 TJ, but I don't find it safe, with the braking distance and roll over potential. I stay in the slow lane, 60 to 70mph and have reached 220,000 miles on my original engine. It might be better to have a Porsche if you want high speed to drive on the highway or Autobahn. Sure, they will whiz by you, by their crashes will end their lives. Stay safe and live long, or get a Porsche, better known as the "Widow Maker".
Welcome! I wouldn't worry too much, for many of us here it's our native tongue and we're less than perfect with it as well.
The TJ top speed was marketed as 108mph.
I’m not doing 60 on Texas Highways, you’re the danger when you do that, and the posted speed is 75 or 80 (or 85 like the 130 tollway).
My TJ has no issue at all at that speed, and it’s as well maintained as any car I’ve owned.
I’m not sure why anyone with a well maintained Jeep would think spontaneous DW would show. F150’s have as much DW issue as any vehicle.
Was probably marketed as a very reliable car too!
