I have it on good authority that unless you install 35's and a lift kit any Sport or Sahara will immediately burst into flames the moment it touches dirt.I'm surprised your Sahara was able to handle that dirt and mud. Seriously, everyone knows the Rubicon is the only model that is designed for off-roading. You are def risking damaging your rig if you keep wheeling it. Saharas and Sports are NOT made for that abuse!!!
