ive got a set of Weld 5-star wheels skinnies for the front and 15x8's for the back,,will the 15x8 fit under the fender or will they stick out???

 

If the backspace on the 15x8 wheels is 5.5", the tires will tuck right under the outside edge of the fender. If the backspace is any less.... they will stick outside the fenders. A 4.5" BS would stick out about 1".
