Time will tell but many Rubicon JL owners have been running 37s on the same axles with no issues so far. What trim are you running?I plan on doing mild off roading with 90% of my driving being HWY with some towing thrown in. Plans are a lift of no more than 2.5 and 37 tires. My concerns are that 37`s might be much for the drive train and steering components . Am i being overly cautious and over thinking this? Thoughts?
