Sorry to be a bother, but I have been trying to understand backspacing, offset and everything else to ensure a proper fit for wheels and tires, and I just want to make sure I get everything correct the first time.

So, will these wheels (http://www.cruizinconceptswholesale....LEGEND&cat=490), fit with this tire (http://www.americanmuscle.com/nitto-...245-45-17.html) in a 1967 coupe, without any modification. What offset should I get? I've read that classics had very little to no offset, so the closest I can get for that wheel would be a +1. When ordering from a website that doesn't give the option of choosing offset, will they automatically choose the proper offset for you?

Thanks in advance.

 

I wouldn't trust any wheel dealer to get the offset right. Check this so you'll know what you want:

I would guess ( and take this with a grain of salt ) but based on the link that 2+2GT gave us, you would need a 4.5" offset. Again, I am just guessing.

This is something that I am struggling to find for my '67 Coupe. I can't seem to find a decent set of rims and tires for her that really met my budget or taste.

Anyone have any suggestions for us?

 

4.5" is the backspace, not the offset.

 

AH.... ha..... see I knew I was stating the wrote value.

Sorry.....

Can anyone instruct me what the "offset" of the wheel is?

 

"Offset" is the distance from the back side of the wheel center (the mounting surface where it fits up to the drum/rotor hat) to the midpoint between the two bead seats. A zero offset wheel puts exactly half of the tire outside of the face of the mounting surface and exactly half on the inside.

Positive offset puts the rim portion of the wheel and the tire closer to the outside (giving you a greater backspacing measurement, and actually reducing the track width). Clearances on the inside, such as to suspension components or leaf springs get smaller.
