Old Tire Size Conversion?
The front tire is a G70-14, that is also marked 205SR-14
So, from the link I assume I should look more towards a 205?
It depends on what you're trying to do.
I found a guy who is running 225/70R14 on the front of his Duster
225/70R14: 26.4" x 8.86"
Seems much taller than the other two sizes
yes! A 'G' tire is a big tire. Factory A-bodies got 'D' or 'E' in some optional packages.
G was a load rating.
We can get a rough idea of the load from a 'reproduction' GR70-14
GR70-14 Firestone Wide Oval Redline Tire
1620 lbs.
And we can also get a rough idea of the original diameter. 27"
205 and 225 are roughly the tire widths in milimeters.
The 78, 75, 70 that follows is the sidewall as percentage of the width.
So to have the same height (rolling radius) on the rear as on the front using the Euro-metric or P metric, it works like this.
Standard everyday type tires: 205R-14, P215/75-R14 should have similar height and load carrying capacity
A wider tire of similar diameter and load carrying capacity will be: 225/70-R14
If you want tire diameters closer to factory, then something in the range of 205/75-r14, 215/70-r14 will be closer.
Those sizes are ballparks. Most manufactures publish the specifics for each tire, at least for when they are mounted on a test rim.
Do check the recomended rim size (width) for the tire before you buy.
