Since I misstyped in my other post and didn't find what I was looking for...

I'm looking to get 33x12.50's for the new ram. 4.5 backspacing on 17" rims.

Will this rub? Should I stick with 11'' wide tires?

 

I picked out a set of 33x11x17 procomps and some 17x8 alloys with 4.5 of back spacing. The guy tells me I gave to get 18's because the 17's won't fit. What do you guys think?

Can I run a 12.50 on there? Does it need to be a 18" aftermarket rim?
