What 19" rims and tire size w/o destroying front diff.

I am considering going to a 19" set up for my car and I have read that if I pick the wrong size I can damage the front diff. I am not a math expert so please try to keep it simple. Furthermore looking to run the widest fronts and rears. Thanks guys looks like the new ride will be p/u today via shipper, pics to follow.

Its got to do with a close matching RPM from front to back. Just saying 305 25 19 doesnt tell much more than its a 19 inch rim and a fat tire.

Pretty sure as long as you get tires that are <1% rolling diameter difference you should be fine.

I think the most useful specification that many of the tire manufacturers give is revolution per mile. The front and rear should be similar in value.

Tirerack lists the specs of each individual tire they carry. To get you in the ball park this is a good tool to start. Keep in mind though, that there are variations between manufacturers, so always verify.
