Help with wheel specs

I am looking into getting a set of Dick cepek DC 2 wheels for my 05 double cab, I am planning on putting the ULK by toytec on my truck and lift it to three inches. I am wanting to get 18X9. What would be the best backspacing and off set to get? I would like to stay away from having to do a cab chop and getting new UCA's to allow for bigger tires. I would also like the tires to stick out a little past the fender flares to get the aggressive look. Any help would be greatly appreciated.

 

At 3 inches, you may need to get new uca's to align it correctly. I have Bilstien 5100 set at 2.5". Im getting 4.5" backspaced wheels with 285's. You will not need to get new ucas most likely and it will save you a lot of money. This will get you the look you want.

 

The UCA's would be for alignment issues, not clearance issues.

4.5" backspacing and 285/65/18's will give you the least chance of having to chop the cab mount...but you still might have to..

 

X2 if you stay on the pavement you should be fine as long as you don't hit big bumps at full lock but you won't know until you install them.
