I found a set of rims I want and im pretty sure they will fit but just wanted to ask you guys if they will fit forsure. I have a 98 1500 4+4. The size is 16" by 8" offset 12 and bolt pattern is 5-139.7mm. What is offset?

 

the off set is basically the backspaing, its either gonna be like +12mm or -12mm, and yes that is the correct bolt pattern, its also known as 5-5.5 or 5 on 5 1/2. what size tire you gonna put them on? and what are the name of the rims.

 

Im going to put 265,75,16. They are MST rims on a sight called buywheelstoday.com They are black with a machined lip.Are they any good? Im assuming the offset is +12mm there is no neg sign beside it. Has anyone ever bought anything from them? Im from canada so not sure what the shipping would be loke.
