Deciding on tires

Need to get new tires on my girl before summer is over.. HELP!! Tirerack.com can't even tell me if I might need a lift kit I want to fit on 30x9.5x15 General Grabber AT2s on my 93 YJ. HOWEVER... I don't know if a 15x7" wheel with 4" back spacing would clear the front axle or if id have problems. Does anyone have a '93 YJ that can help my objective is to get the big tire look and feel without any lift kit. Thanks

I believe 30's are the largest you can go. I put 31" Dick Cepek's on my 95 and they rub on anything approaching a full turn. 31's also look pretty stuffed into the wheel wells without a lift.

1995sahara757 how does it run with the bigger tires? Big change in power or acceleration?

The stock tires are about 8"-8.5" wide, and the stock rims have either 5.5" or 5" of backspace. So with 9.5" wide tires, you'll want at least an inch less backspace, so 4" of backspace would suffice to maintain turning radius without rubbing the swaybar, and still allow room for upsizing the tires to 10.5' wide in the future. The tires will stick out a bit compared to stock backspacing, but that will help add to the look of bigger tires.

FWIW, even 31" tires with a 1.25" shackle lift look really stuffed. When I had this setup (put on by the PO) I had friends who weren't off-road enthusiasts or Jeepers tell me that the tires looked too big for the suspension. It just wasn't aesthetically pleasing nor well proportioned. Just food for thought. You might want to consider a small lift to better fit the tires you want.

All stock. Got the 4.0 inline 6. Not sure what gears I have. Either 3.73 or the 3.53. Yj's came with one or the other I think.

If you all need more room to fit the 30's(which fit fine stock)or more room for 31's...You can swap in a set of TJ fairs. You will cut some sheet metal. .but makes a world of difference.

I'm gonna resurrect this post if I can... All of y'all with the 235/75r15 what kind of RPM are y'all running at actual 70MPH, not what your speedo reads? The reason I ask is I am try to figure out if my gear ratio is the stock 4.10 or if it has been changed to 4.55
