I want to know if 215 will fit on an 8" wide rim. and also if a 245 will fit on a 9" rim will they fit fine or will they be stretched abit let me know.

Thanks
Tony

 

Those tires will fit, but a better match would be a 225 on an 8" wheel, this combo gives fairly straight sidewalls without being stretched at all, a 255 on a 9" should give about the same effect (same amount of difference between tire and rim width).

When I put my 225/45/17 shod 17x8's on the ground lying flat on their faces the rim lip/bead/whatever you want to call it touches the ground ever so slightly.

 

so would 215 be stretching it too much or would it be fine.

 

For most tires, an 8" wide wheel is the widest recommended for a 215, a 9" wheel is the widest recommended for a 245.

 

You could probably go with an 8.5" wide rim with the 245 and save some money and have a lighter rim.

I have 9" wide rim with 255s and they fit well. I would think the 245 might be a bit stretched on my wheel.

Tire Rack's site has some good info on recommended tires/wheel widths.
