So I have the stock 275x65R18 wheels and tires on my 2018 with a 2" level in the front. I want to put 305x65R18 Nitto's on the stock rims. My question is will I have any issues with rubbing anywhere. I'm mostly concerned with the inside of the tire rubbing the pivot arm. (not sure if that's what it is called "pivot arm"). There's not a whole lot of clearance in there now. Any you guy's running them?

 

You'll be about 1/2" closer to your upper control arms, and everything else right there.

Which Nittos? Some of them run a good bit wider than their size leads you to believe. Look at the actual inflated dimensions before you pull the trigger.

Suspension clearance is my biggest concern. especially the control arm.

 

Gotcha. That is actually 12.25" wide, a 305 should be 12.008", so you'll actually be 0.725" closer to the control arm. I would advise now measuring from the tire to the control arm. I don't remember what the stock spacing is now, but you might be able to run a 1" wheel spacer (that way it has new lug studs on it, can be safe if you get the proper spacers) and clear those tires.

 

may end up rubbing on outer edge of the crash bar/ front bumper. I put them on my boss’s Raptor with a 315 tire and that’s what happened. The inside clearance was fine but it pushes the pivot point of the tire out and that’s where there problem is.
