If you HATE the way they size tires.. Even if you know metrics well, you
still do not know exactly what the sizes of the tires are.. Now you do..
The TOP chart is all 17" tires and wheels..
1. Section width varies approximately 0.2" (5mm) for every 0.5" change in rim width.
2. The sizes shown are average design values for tires measured on specified measuring rim widths.
3. These should all fit on the 7" wheel..
4. Use these charts at your own risk..
This chart has smaller 17" tires
and includes a couple of 18" tires and wheels..
.
this just makes it a little easier when you are planning on putting different
tires on your Challenger to see at a glance what size is what..
