as i mentioned before im just gettin into this... what is the wheel backspacing???

 

Backspacing and offset are kind of the same thing. The higher the number of backspacing the more it will tuck in under the fenders. The lower the number the more it will stick out. 6 inches of backspacing will tuck in more than a wheel with 4.5 inches backspacing. As for offset a negative offset will usually go with a low backspacing. -12 offset 4.5 inches bs. A positive offset will generally go with higher backspacing and will tuck in. 6 inches bs and a +25 offset. Hope this helps.

 

This will give you a little insite. As you begin your mods you'll want to make sure you have the correct offset on your rims to prevent rubbing...

I have a 98 F150 with stock wheels and 33'' on but i want to get the tires outside the wheel wells further. What type of back spacing do i want to use

Tech.... Don't think his response should surprise you... YOu've seen this before.... lol

 

lol...you would think huh ??

 

thanks the lift im buying calls for a 4.5 so ill go with that lol

 

I've also seen some lifts on websites that require that... Call them directly... That's what I did and they will give you the full specs..

 

4.5 backspacing with a -12 offset, will this stick my tires out pretty far? especially compared to my stock rims
