Bato65 Posted June 21, 2018 Share Posted June 21, 2018 I have a 63 Riviera with original drum brakes and considering the Riddler 695, 18x8 rims with 235,55,18 tires for a total height of 28.2”. I believe the original tires were 225,75,15 with a height of 28.3”. Based upon what I’m reading here I should be good with this tire and wheel combo without spacers. True?

steelman Posted June 21, 2018 Share Posted June 21, 2018 I am going to say no, not without spacers. Overall height is OK, but the 63 has the larger center hubs. From what I can find, the center bore diameter on this wheel is 83.82mm, or 3 5/16". I think the larger 63 center hub is 3 3/8 or 3 7/16". You need to check. Front or rear, they are the same. The center bore of the wheel must clear the outside of the hub that sticks out past the face of the drum to seat properly. If the hub is too large, you will need a 1/4" spacer to allow the wheels to seat properly. Also don't forget lug studs on the drivers side of a 63 are left hand thread. Have to check lug nut availability or change the studs. 2 Link to comment Share on other sites More sharing options...
RivNut Posted June 21, 2018 Share Posted June 21, 2018 IF you're buying them new, and IF you're buying directly from the manufacturer, you might be able to have them mill the wheels with the hub clearance you need. Wouldn't hurt to contact them. 1 Link to comment Share on other sites More sharing options...

The center bore is 3 3/8 and seemed to fit over the 63 drum brake hub. I assume I would be good to go with those for the back. Just need to find some left hand thread lugs and the right tires.

Left hand lug nuts are pretty common. Many early Chrysler products used them. Check JEGS or Summit Racing to see what they have. You need 1/2 by 20 threads. 4.5 inch back spacing is going to put the inside of the wheel and tire pretty close to the chassis and suspension. Make sure you check the steering with the tires mounted and the car is sitting on the ground, not on a rack. Go over a curb or two at full lock to check for rub. I had 225/70R15 tires on factory 6" rims with the factory back spacing on my 63 and my tires rubbed the frame at full lock. Link to comment Share on other sites More sharing options...

I’m hoping I can get away with the 4.5 back spacing on the back, since I buoghtbthose rims. What back spacing would you recommend for the front?

What back spacing would you recommend for the front? It depends on the wheel design. You'll just have to do a trial fitting. Really difficult to buy wheels that fit if you're trying to find stuff on Craigslist. 1 Link to comment Share on other sites More sharing options...
Mass9192 Posted August 10, 2020 Share Posted August 10, 2020 Just a FYI I was looking for some 695 ridler wheels and came across this feed for information. Just wanted to give an update on the wheels. I put on 20s on my 63 Rivi with all stock drum brakes but staggered 20x8.5 front and 20x10 rear. These didn’t fit snug with center bore so just a heads up you will be needing spacers or have them billed just a bit not to much. Also go with the 0.125 thickness of spacer so you have room for the threads. Link to comment Share on other sites More sharing options...
Bato65 Posted August 17, 2020 Share Posted August 17, 2020 I put some Riddler 695 on my 63 Riv with factory drum brakes. I had the same situation. They didn’t seat snug against the center bore. All I needed was about 1/2 mm. I took a metal router and took 1/2 mm off the top edge of the Riddler and it fit great without spacers. 1 Link to comment Share on other sites More sharing options...
Mass9192 Posted August 17, 2020 Share Posted August 17, 2020 That’s awesome! So no need to take to machine shop. You did it yourself? Can you tell me what type of metal router you used if you don’t mind. I think that’s something I would want to do instead of the spacers. Thanks!

Bato65 Posted August 17, 2020 Share Posted August 17, 2020 Your best bet is a local machine shop, but you’ll need to remove the tire. I did it myself because I didn’t take much material off. It was while ago, but I believe I got router bit for Aluminum ( carbide tip) cutting bevel trim 45 degree x 31/32. Check around for other expert advice. Hope that helps.

Mass9192 Posted August 17, 2020 Share Posted August 17, 2020 Ok good to know thanks! It’s fine right now but would of rather gone with rims being flushed with drum brakes. Thanks. Link to comment Share on other sites More sharing options...
