Some questions for anyone who is deep into tires.
1. What is the proper radial equivalent for a 670-15 bias tire: 205R15 or 195R15 (considering section width (7"), tread width 4.5", and inflated diameter 28")?
2. If looking for a tube for a 670-15 bias tire (with a section width of 7"), is a Firestone FR15 (good for radials and Bias) acceptable? Or, any tube that would fit between a 195R15 to 215R15?
3. How does a replacement tire, with a smaller inflated diameter, affect the accuracy of the odometer and/or speedometer?
Thanks,
Doc
