I'm going to say wait. Go look at my old pics in the tech thread of what my stock tires on a 2.5" lift look like....... Weren't 32's but still.
Put it on with the tires. That way it just totally skips that whole awkward puberty stage of being all gangly and goes right to looking mean. Stock to BAM awesome!
If you have an auto with 4.10 gearing you might want to think about gears, and you'll likely NEED a programmer to fix the shift points stock or re-geared. If you have a manual it'll just fix your speedo. And you can work with the gearing. I've got 3.73's (thought 3.21's before) and it's "manageable" as a manual if you're heavy footed.
Get some "c-gussets" welded on your front axles so you don't break the knuckles off. Can buy some, or just get some metal and make it work.
I also wish I bought 37's instead of 35's......
