Considering going bigger...

[jp3]

I just put 275/70r18 (33") on mine and it did pull the back wheels forward slightly but not enough to even come close to rubbing.

Usually bigger tires just means accelerated wear of parts such as wheel bearings & brakes - the trans could perhaps see increased wear but who is to really say? The heavier tires can induce some handling oddities but nothing too severe. I've always understood it is a good idea to replace the brake lines with braided ones especially if you have bigger, heavier tires. The rear links, brake lines, & driveshaft will not need to be adjusted/lengthened. I did flip my BJs & I replaced my CV boots but I also fabbed up drop brackets for the diff as well. Be sure you consider lengthened rear bump stops also. I also installed the low-profile front bump stops for slightly more droop & even then the stock length brake lines were safe. I went from the tire size you have up to 32.5x11.5 & got after it in the front wheel well just so I did not have to worry about any rubbing. If I remember right, there was none.

I hope these pics help...
