Factory Buick rims with lug lock set.
tires are needing replacement. Rims in good condition never been curbed lots of life.

 

What is the factory rim size? I have a 1987 Buick LeSabre LS. The all seasons on it are 205/70/R14 (factory 205/75/R14). How can I measure the width of the rim with the tire on? The bolt pattern seems to be 4.5 or 114.3 x 5. I have a set of rims that came off my old Cutless Ciera S. They are 114.3 x 5 bolt pattern which actually fit the current bolt pattern but they are 5.5 inches wide.

All of the factory specs I'm seeing online say this generation of Buick should have 115 x 5 6" 70.3 bore. I just bought a set locally which are the exact specs in mint condition but the bolt pattern doesn't fit! I called my local GM dealer and he couldn't confirm the factory size as they don't have the old catalogues.

I've been dealing with this for a long time now. I need to get winter tires where I live as I do a lot of highway driving. Manitoba, Canada.

Any info would be appreciated!
