Info for leveling 2018 TRD Sport 4x4

Going to trade my 08 SR5 for a new TRD Sport 4x4 tomorrow. I know that I want the truck to be level and I know that I want to trade out the 265/65/17 tires for 265/75/17 all terrain tires. I'm going to let the dealership do this for me and add it in the total cost so nothing is voided on the warranty.

Any suggestions on what I should tell them as far as what type of lift and will it need a block in the rear to make it level? Will 265/75 tires look big enough? I have to travel 35 miles a day one way to work so I do not want to kill my gas mileage.

Thanks

 

Dealership is going to overcharge you for the tires, changing tires will not void a damn thing no matter who does it. And the tire size is 265/70/17, and that upgrade will basically do nothing to the gas mileage. And please do more research on lifts and such, as most leveling kits are hockey puck spacers and blocks. Good Luck with whatever you do.
