Needing new tires
So technically my 225/70/14s are too big?
Ok, will that cause problems?
Yes, assuming your rims are 5" or 5.5" wide your current tires are too big. As far as problems, it depends. 225/70/14's should be mounted on a 6" to 7.5" wide rim. If your current rims are 5.5's you probably won't notice any of the possible negatives- poor tread wear patterns, decreased handling performance, etc. Not saying those things can't or aren't happening, but it should be a fairly minor issue. But if you're current rims are 5" wide then those issues will be more pronounced. The tire is squeezed on the rim, that will tend to make the tread profile more round, meaning more wear in the centers and a taller than spec tire assuming you run the normal air pressure. If you don't run the normal air pressure, then you will see better tread wear, but reduced handling as the sidewall stiffness will be decreased. At normal pressures, the additional load on the sidewalls from being squeezed onto the rims will still hurt handling, and at lower pressures it will be even worse.
Just looking at your current rim/tire combo you can see that the sidewall bulge is pretty significant, there's a lot of flex there. It probably isn't noticeable just cruising around town, but put a little side loading on there and the car will feel pretty sloppy.
