Hi Guys, Need helps for the new rams

I got 265/70r16 factory size tires on my 05 trd offroad and it is 90% new.
I really want to get a new set of rims and bigger tries such as 285/75r16 later on. but my budget is not enough to change everything at one time.
So, i decided to get the rims first. The question is what size rims should I get which will fit for my factroy tires and also will fit the bigger tires in the future? 16x8?
what is the offset of the wheels? what should i consider before buy them?

sorry guys my spelling sucks, eng is not my first language~

 

rims?

 

at first i was like... hmm, 'a' isnt even close to 'i'...
but 5 times...?
rams?

 

Computer accent. Interesting.

 

At first I thought he needed help with this dodge ram.

 

or fleet of dodge rams...

 

come on guys, enough with the flaming.. He already said that english isn't his first language. Since you guys would rather make fun than help, I will. If you want 285/75/16's, you're going to have to lift the truck. If you replace the rims you'll want to go with a 16x8 or 16x8.5 with as low of an offset as possible (from 10 to -6). If you have any other questions, feel free to PM me with any questions.

 

To further clarify. If you want 285's, you need 0 to -6 offset with a 8" rim.

If you only want to fit 265's, with an 8" rim, any offset between-6 and +25mm will work.
