17x9 on 285/70/17

I'm getting new tires, 285/70/17s and the wheels I have now are 17x9, 4.53BS and -12 offset.

I'll be putting new UCAs and coils to achieve around 2.5" of lift. How bad am I going to rub with the wide of a wheel and -12 offset? I'm just trying to figure out if I will need to do a CMC or not. I'm thinking I will but..I have a friend who just put on the same size tires and we think the same wheel with no CMC.

Also, does anybody know what alignment specs I should be aiming for?

 

I had a 3” lift when I first put on my 17x9 -38 wheels w/ 285/70’s & I rubbed.

 

Shoot for 0 toe, 0 camber 4-4.5 degrees of caster then check for rub. Then it will depend on how hard you wheel off road.

 

Yep, -38 will do that.

 

Thanks for that info! I'll see what they can do. I'll probably hold off on doing the CMC until I see if/how bad I rub. It's an extra $300 for him to do a CMC for me so I wanna hold off if I can!

 

I’m now 4” of lift & don’t rub at all. Haha

 

They say an extra inch is always good.
