I just made an appointment to have this installed next week. I have the 20" factory rims on my 06 FX-4 and drive about 80 miles a day back and forth to work. What size tire now to make sure the wheel wells are filled up?

 

33's will look good, you can fit 35's I believe.

Show me alot of pics when you get done, I am thinking about this exact same setup. If you could do a before/after pic.

 

If you go 35's, you'll be living at the gas station if you have a 80 mile round trip commute. I'd stay with 33's. I have the same setup as you so far, but still on the stock tires.

 

Thanks and I will make sure I take before and after pictures and get them uploaded to the site.

I am thinking about the 305/55/20 Toyos or 285/65/20 BFG's?
