Might look dumb but I don't care about that for a couple weeks.

With the bigger rubber you will be slipping the clutch a bit to get her moving. The mismatch in tire size and gear ratio is much easier to live with when you have an auto tranny. Just do like Eric said. Don't be in a big hurry to get your Jeep moving and keep the slippage to a minimum and you will be fine til you can affard to swap your gears.

I am going to upgrade the gears for sure but it's not in the immediate budget so any advise or help would be appreciated. Thanks,

If you go with 12.5 and want spacers I've got some from my Jeep I'd be willing to sell cheap.
