will the wheels from a 89 blazer fit a 99 jeep wrangler- tires are same size but are the lug bolts the same ??
Head over to http://www.tirerack.com and find wheels for both vehicles-- they will tell you the bolt pattern and if they’re the same they will probably fit, although rarely wheels will be incompatible due to other factors, such as the center hole size.
You also need to match the center hole size and the offset (the distance between the mounting point and the center of the tyre.
Good way to find out is to try it.
In the past GM and Chrysler wheels would not interchange. Today, who knows?
