How much room is that? As a test fit we tried putting the current rear wheel/tire (19x11 with a 325/30-19) on the front just to see. The backspacing wasn’t ideal but we had to start somewhere…
"Lot’s" of room:
Not ideal but as I said – just a test. I wasn’t planning on the 325 tire up front and the backspacing is off by about 0.5” so our target tire should fit fine. HRE is just down the street and around the corner so they were going to stop by when we were ready to get specific.
And just for comparison - with a current 275/30-18 front
