rim question

k i found some rims for my truck but i wanna find out if they fit or not before i buy them,the bolt pattern is 5x100,and it has an +38 offset,and they are 18x7.5,how do i find out if they will fit,and if they will or wont stick out with the current fenders.and if the bolt pattern is the same,

toy bolt pattern is 5x 4.5 or 5x114

I think you need a +40mm offset or more to tuck. But you would also need the correct bolt patern.

oh ok thanx man

would a +50 offset be good cuz i noticed a rim i liked and its got that offset in a 18x7.5

Yea, that would tuck. basically anythign with more than +40mm offset will tuck. Thats the distance from the center of the wheel to the face where your hub meets the wheel. So the more MM there, the farther in the wheel will be.
