I'm want to buy used tires (almost brand new). The tires I'm getting came off a GrandPrix (the ad said "2002+ Pontiac Grand Prix, Chev Impala") the numbers on the tires match the ones currently on my Sienna 215/65/R16 98T. My questions is when I've looked up the bolt pattern I see the Sienna has a pattern of:

OE: 15x6
Bolt: 5x114.3
Lug: 12mmx1.5
CB: 60.1
ET: H

and the Grandprix/Impala has a pattern of:

OE: 15x6
Bolt: 5x115
Lug: 12mmx1.5
CB: 70.3
ET: H

My real question is will these Grandprix/Impala tire/rim fit on my Sienna and is it safe? I have no idea what the above numbers actually mean but I can see that the Bolt and CB numbers are different.

Please help!

Hi darrylsteam. Welcome to the forum. Just have the tires switched to your rims. Besides the different bolt circle pattern, the center holes will be different diameters. Those holes are important for holding the wheels' centers so they don't stress the lug nut studs. It is also possible for the taper of the nuts to not match a different manufacturer's wheels. That friction surface is what prevents the nuts from working loose.
