We just got some `04 STS rims from a friend of ours to put on our `97 Seville STS. I know the lug patterns are the same and all, but just want to make sure that the offset shoudl also be the same, and does it matter which rim the tire company puts on front of back?

Also, the tires that I have off our lincoln which is being salvaged are Yokohama 245/50-16's, which we'd like to put on the Caddy, seeing that the Yoko's only have about 2,000 miles on them.

How far off will those tires throw the speedo!? Thanx in advance for the help!

Kewl! Thanx for that link! I've been looking for that for quite sometime now. It says those tires will be 59.8mph when doing 60, so that works for me!

As far as the rims go, those should all still be the same offset and everything, correct!?
