I got up to 65MPH without any issues. But the tire guy said it may be difficult to balance due to the weights needing to be on the backside of the wheel and the fact that the center section is almost at the midpoint of the wheel.

Did you end up with 275/40/17's all the way around?

Yes - 275/40/17 Nitto 555's at all 4 corners. I think that is the max size up front. If they sold 17x10's I would have put more rubber in the back.

I'm surprised this thread doesn't have more activity. These wheels must be getting a lot of guys excited.

I'm thinking about them for my '69. I've never liked the fact that the car rolls on 14" doughnuts.

I have a 67 Bird. I want them. I have been waiting for almost a year. YO has horrible customer service and sales from my experience. I just stay away normally. I called because I saw that 69 with them and I wondered how they did it. 255's or wheel well work, etc. The salesman said the 69 was 100 yards from him. I would have thought he could have walked over or just asked. But no I guess if they can't keep them on the shelves they aren't gonna work to answer Q's.

I think I'd pay 50.00 more just to not talk to them.

Maybe a sponsor will buy a bunch and gives us some customer service.

Anyway if anyone is in ATL and can look at them for us that would be awesome.

I'm building a 70 formula and have 14" baer aluminum hat rotors with 06 ZO6 (i've sold these and am planning on using the 2013 ann vet which are the same but diff color) 6 piston calipers.
Just wondering if the brakes will fit in these wheels? I was planning on running aftermarket wheels but these look to nice not to run them. I may even have the rears widened to 10-11 inches.

Default maybe a better balance solution

I'm liking these wheels as well and may want to choose to use these whenever i can complete my project65. I may use Dyna beads as they've impressed me in both the use in truck tires and on my bike.

Default balance

I'd like to know if these new wheels are hub centric or lug centric or both. The concern comes from the Vintage Wheel Rally II's which require a really old tech bubble balance because the lugs are not centered with the hub and you can not do a modern spin balance on them.
I'd also like a solid answer about the tire size fit up front on a first gen.

Anyone looked at a 235/55/R17 tire? That is around 27.2" tall. Some manufacturers also make a 235/50/R17 which is 26.3" tall. Really like the wheels, just need something around a 26.5 - 27" tire on an a-body. Just my opinion.

Totally agree on the height issue Doug! The problem I have with a 235 width tire on these 9" rims is the tires are narrower than the rims. Which I think looks horrible, not to mention doesn't actually work very well... I wish these rims were available in an 8" width.

There just is not a 17" tire that works with these rims on an a-body in my opinion. The 275 40 17 is only 25.5" tall. I personnally like to keep the tires close to factory height... Filling the wheel wells should be the objective, not making the tire disappear.

Oops, thought the wheels were 17x8. Damn that would be nice...

255/50/R17 is 27.1" diameter.

Time for a fitment gauge. 255 on a 9" wheel on an a-body...might be tight.

I'm thinking that would look pretty good. Post if it fits! Otherwise I'll probably be waiting for some 17x8's...

Are we talking about 17x8 on the front too? I would think the front end would have to be modified to fit a wheel that wide.

I did a test fit with some Boyd Coddington 17X8's on my car and there was no way it wasnt gonna do some serious rubbing.

Ive got 275/60/15s on an 8" wheel and ive got plenty of room on both sides. If i had a 9" wheel wirh one more inch of back space it would be perfect

Default Have the wheels and tires are on the way

I recently received the wheels and performed a trial fit using the bare rim. The car is a '68 Firebird with stock width rear axle, original subframe, suspension components, drum brakes, and has been lowered about 2" all around.

Rears fit well with approximately 1 1/4" space between closest point of wheel housing and rim lip. The lip of the rim sits within the wheel housing by approx. 3/4" in from the qtr. panel lip.

Front fitment is an issue on my car. There are two major issues and one potential cosmetic issue. I won't know for sure until the wheel/tires are mounted but it appears the maximum front tire diameter that can be used without rubbing the fender with the wheel turned is approx. 25" - 25 1/4". Also, the replacement steering knuckles (attached to tie rod) are two different heights (one is about an 1/8" taller than the other) and the driver side sits closer to the rim than the passenger side. This results in a rub of the wheel lip with the knuckle on the driver side. As far as cosmetic issues, the 5" backspace and 9" width has the wheel rim sitting approx. 3/8" in from the fender lip.

To rectify some of the issues, for now I removed metal from the steering knuckle that was rubbing and will create a 1/4" spacer to move the knuckle attachment points away from the wheels. The tire size/mfg for the front is 235/45 Nitto 555 and 255/45 Nitto 55 rear. I too am concerned the front tire width may be a little small but we'll see. Also, I hear they may be coming out with an 8" rim in the future. I think the perfect combo for the front would be 4.5" back-space and 8" width. I will post pictures after everything is mounted.

I have done alot of reading in the last year and it appears most people are successful on the front with 255/40/17 on a 8". That size is right at 25.2" on most tires. I think a 245/40/17(24.47") up front and a 275/40/17 on the rear would put you in the best place to be successful and still have some nice rubber. No doubt 2" drop or maybe more would be necessary to have nice look with not too much wheel well. If you could get some different sizes I'd try that. I think yours are just too tall.

Thanks for posting! Regarding the front, you mounted the wheel and set it down on some blocks or something to check this out? Sometime could you lift the car to about stock ride height and check it? Also, when you mention the maximum tire size of approx 25 ¼” before rubbing the fender, are you referring to the lower, outer, rear corner when turned about 30 degrees? Thanks
