As long as you have a 2007-2012 Jeep Wrangler or Wrangler Unlimited you would not need to replace the factory bumper to install this Bestop HighRock Oversized Tire Carrier # B6196101. This product installs onto the Jeep tailgate and does not require drilling or modification.
I attached installation instructions for the product for you to check out also. view full answer...
According to my calculations, a 325/65/18 tire is approximately 35 inches in diameter.
The Bestop HighRock Oversized Spare Tire Carrier can handle tires with diameters up to 37 inches weighing up to 200 lbs, as long as your tire/wheel combo weighs less than that, the Carrier will work great for you.
