Ok, I'm looking at buying new rims and tires for my 2004 F150 Lariat SC 4x4 and would like to know if I would have any fitment problems with the following configuration:
Wheel: 20x9 6-135 w/ 35mm offset
Tire: 275/60R-20 119S or 275/65R-20

I don't have a front leveling kit installed and also need to know if it would require one?

Thanks,
Richard

 

What backspacing does that work out to be? If it's 5.5 or 6 inches the 275/60-20's should fit.

 

The 275-60-20 will fit with no problems. If you do go to the 65 series some minor modifications would be needed

 

The Backspacing on the wheel is 5.55".

So what minor mods would I have to do to accomodate the 275/65-20 size tire?

 

The backspacing is perfect so I doubt you would have to trim. If you do, it will probably be the rear corner of the front fenderwell/flare.
