sometimes when you tighten the wheel nuts it may still not go in 100% centre. so you may notice a small vibration on higher speeds or notice that the tyres wear out weard.
it also holds stronger on the wheelhub.
cos instead of just beeing tight on from nuts its also tight from centre.

well thats what they told me in car scool and tyre/rim shop.

Well that makes sense, all wheels should have them then, I guess.
I would imagine they come in different diameter's based on your hubs....
So what diameter would we need for the Riv.???

One rim that Ive always wanted and I can never find nowadays is a 20" KMC Unit wheel. There was a drug dealer who's wife lived across the street from me and he had a Corvette with 20s on the rear and 19's on the front and they looked so damn good but I couldnt afford them, then a few years ago a guy had a pair on 20s and sold them for $250 to take his girl out on a date for her birthday and nobody told me until the day AFTER he sold them.

Scott, do you remember what brand name the aluminum rings were?

Rick, the Riviera has a 70.3 mm O.D. hub and you would need to know what size the I.D. is of the wheel you're getting to get the right adapter.

Basically the adapters center the wheel on the hub while the lugs do the clamping. What Timo said.

I found this place but they are plastic. So are the Gorilla and American Racing.

Thanks for the info.
I saw some aluminum ones on one of the sites that i looked at while looking for aftermarket wheels. I'll have to check all my bookmarks and see if I can find it again.

I don't know the brand of rings that I got. The place I bought the rims (global wheels on eBay) set me up with the rings.

Well finally got around to posting these. My wife wanted chrome. Well she got chrome. They do gleam when the light hits them.

Recapping: Vagare V9 Mayan 17x8 and General Exclaim UHP 245 50R17.

When I saw one picture of them I was afraid they would be a little too "open spoked" for me, because I don't want to have to make the brakes look nice, but they are just right. They are the same height as the factory tire but because of their extra width they really fill in the wheelwells nicely. Gives it a much more hunkered down look.

I'm thinking about 1" of lowering down the road but one problem is when I had a passenger in the back there was some minor rubbing on bounces on the top of the tire in the back. Right now the load leveler is not working so that will fix that but I will have to be carefull about lowering it.






I got the wheels from Summit and they came within a week even though they did not ship from their warehouse but from their supplier. The big thing is they didn't charge any extra shipping so their price was competitive with other internet places that charge shipping. The tires came from Tire Rack and took no time at all to get. Pretty much overnight. You're a little limited on selection at this size but it turns out this was the cheapest tire but it was very highly rated. The 225 55R17 size had plenty to pick from but I wanted the extra width. If I would've gone for the 18" size it would've added about $200 to the total cost but opened up the selection of reasonably priced tires a bit. As it is these tires seem to be hooking up when heavy throttle is applied off the line so that is a plus and the ride is pretty much unchanged except for the better handling. If it was my car only I would put up with the slightly harsher ride and go for the 18's.

I got "hub centric rings" from www.vortextuning.com through E-Bay for $9 total and they only took a few days to come in. They are plastic but they did their job. Also I picked up a set of Dorman Spline Drive lugnuts from Advance Auto. I figure that will slow down anybody that wants these wheels.

All total it cost around $1300 for everything so even for a fairly inexpensive setup it is not cheap. The UHP's are summer tires and they work well even driving in heavy rain but I'll be running my skinny Yoko 205 65R16's on the factory rims for winter driving which will also preserve the chrome. These babies have to last!
