I drove my buddies new JT on 35’s and it was fine with the 345’s, but it has an automatic transmission. I’m not sure how a manual trans would perform.

Why do I own a CJ? I like to “Balance the wrench and the steering wheel”

This is a very helpful tool in deciding to regear or not and what years to go with.

Too many mods to list. Too awesome to sell.

I just realized my buddies JT might have 373 gears, so that is not a good comparison, however; I believe you would be OK on 345’s with an automatic.
