mp65riv Posted February 18, 2019 Share Posted February 18, 2019 I'm looking at American Racing Wheels for my 65 Riv - the website is coming up recommending 15 x 7 wheels with a 5 x 4.75 bolt pattern, with a 3.75 inch backspace. Any thoughts as to whether these will fit and what my limits on tire size will be with these rims? I'm not planning to modify my wheel wells or inner fenders.

RivNut Posted February 18, 2019 Share Posted February 18, 2019 Those are for the intermediate sized Skylark, Regal bodied cars. You need a 5 on 5 inch bolt pattern. Link to comment Share on other sites More sharing options...

mp65riv Posted February 20, 2019 Author Share Posted February 20, 2019 Looking at American Racing VN1055773 - 15 x 7 with 5 x 5 bolt pattern, 3.760 backspace. Any insight on whether these will fit without much drama? Link to comment Share on other sites More sharing options...
RockinRiviDad Posted February 21, 2019 Share Posted February 21, 2019 Someone posted a pic of a tool in the link I posted. That tool will help u take all the measurements u need to figure what wheel will work. The pic shows a pro model tool. I believe it was priced as such too. When u do a google search u can find cheaper versions that are made more for us DIY home garage guys. Link to comment Share on other sites More sharing options...
RivNut Posted February 21, 2019 Share Posted February 21, 2019 Here's a chart that shows the dimensions of the Buick rally wheels. You should be able to look at it and compare the wheel your looking at to what was original. 3.760 backspacing on your wheels compares to 3-3/8" or 3.375" as a decimal equivalent. Some guys are running the 71-78 wheels on their 1st generation cars and the 3-7/8" back spacing equates to 3.875 as a decimal equivalent. The one thing you'll want to make sure of is what the "Wheel hub diameter" is on the wheel your looking at. For your '65, you'll need a wheel hub diameter of at least 2-3/4 inches.
