Tires: Tire sizes, oversized tires, series tires

Question
Hi,
96 Dodge G Caravan should be 215/65/15 but is 215/75/15, 2 tires 70% OK. What should I do?

First, it is a bad idea to have different tires around the vehicle, unless the vehicle was designed for that.  Yours was not.  

Different tires around the vehicle can cause some unexpected handling problems, particularly in the understeer / oversteer area.  So the first opportunity, you should get this fixed.

The oversized tires don't bother me much except that they might rub. All other things being equal, the 70 series tires should be on the front to minimize the potential for oversteer.

Hope this helps.
