That size tire came stock on an OEM 17x7.5 wheel so unless the OPs Wrangler is a super sagger it should be fine. I think when the time comes for new shoes I'll be rocking 255/80R17s. Yes, I like pizza.
I hear you. I probably have 10 years on you and just did all the shocks & springs on mine. I just took my time, didn't rush, or beat myself up. When I was younger I was quicker, but dumber in some ways too!
