33.5 tires and regear?

I swore I wouldn't go down this road before I bought my jeep, but here I am.

I've looked through various forums but didn't see anything that exactly answered my question. I have a '13 sahara, automatic, with 3.21 gears. Stock wheels/tires are 255 70 18, which is 32.1". I also have the TF coil leveling kit installed. This is mainly my DD.

I want bigger tires, but not 35s. I found 3 tires that are roughly 33.5". LT306/65/18 BFGs, LT325/60/18 pro comps, and LT 275/70/18 toyos.

1. Will that 1.5" make any real difference in appearance?

2. Will I have to re gear?

3. Will the TF leveling kit accommodate a 33.5" tire?

4. Any downside to running LT tires on a jeep?

Any help is appreciated.

1. Not that big a deal in appearance.

2. You don't have to regear but I have 3.73 and auto with the 3.8.. I have the procal to adjust shifting and it feels OK. I seem to still leave most people at the light without trying. But 3.73 is a far fry from 3.21.
Worst case senario is you regear later. IG you have the extra HP with the 3.6 it will probably be OK

3. Yes and it would work without it except when really flexing.

4. No difference. They are made for trucks and a jeep is a truck (not a pickup truck like most people refer to a truck)

Respectfully dis-agreeing on appearance. I did basically the exact same thing in a 17"- and it makes a big difference in appearance (and clearance). I don't have pics on my IPad of it stock- but this is on 305/70/17 BFGs (33.7). Much better than stock. Then I went to 35's. Random people came up to me and said "nice Jeep" immediately after install. Does the average person notice? Maybe not. But any jeep or truck owner will.
And you might rub a little on the trail- but not on the street.

Thanks. Did find a pic of the stock tire against the BFGS, but only for the width, not height. The BFG was noticeably wider. Just can't find something for height.

Any other advice/thoughts are appreciated.

the LT will be a rougher ride due to the stiff sidewall.
