That is way to positive offset IMO.
Buy the Moab's sell the tires. That is what I did, almost got free wheels.
When I say it looks 'tight', I mean it physically looks too tight not the vernacular.
The SO doesn't like the Moabs but like the 5 and 6 spokes, I sorta do too. If I got the Moab's I'd probably drive on them since I don't really have the money to put into new tires. Spent that money elsewhere.
Although if I was going to roll on 31's I could just buy 31's and put them on ly 15x6's.
