confirmation please

I am taking my stock 2014 platinum to get 5100s on front and back. Front will be on top setting. Currently have stock platinum rims that i actually really like the look.

Question, with the level kit (bilstein 5100s) can I run 285/60/r20 with out any cutting. I read the first post in this section and from what I read, I can.

Second question: The very first post says that the 285/60 is 1.5 inches taller than the stock 275/55. How will this affect my speedometer and or odometer?

Anyone see any issues with doing this?

 

According to the "largest tire you can fit" thread like you said you read...yes
will it affect speedometer? yes.
plug in tire sizes here to see info on how much and all.....
