@KCPitts Were the rear wheels custom ordered? I cannot find 5.00 backspacing on any American Racing wheels

 

[KCPitts]

Yes they were. The fronts are the standard 105’s and the rear are 205’s. The cheaper 105 have a standard backspacing and are a 1 piece wheel while the 205’s are 2 piece abs can be ordered in a custom backspacing. They took about 3 months to come in. Also they stress not exactly identical but you have to look closer to tell the difference. One has a chrome outer ring and the other is polished.

Quite the up charge on custom orders! Geeesh

They were not cheap. But looking cool is worth the price!

So….. I am one of the unlucky ones
67
15x8 4.5BS
255/60’s on rear
Just slightly rub on certain conditions
Back to 245’s it is 🤷🏻‍♂️

I am embarrassed to say that ive spent more time researching wheels than i have on my wife's engagement ring.

After months of back and forth Ive settled on 17's!

I picked up American Racing VN215's--17x8 +8mm, rears and 17x7 0mm, fronts.

Tire choice is the next big obstacle! The Nitto NT555 G2 appear to be the overall winner, but i cannot decide size.

Looking for some advice. Hoping for as much aspect ratio as possible so to not look like rubber bands.

I can relate as it was tough for me to decide on wheels and tires for our 69 GTO.

See this post where it shows my set up using Year One 17" wheels and Firestone Firehawk Indy 500 tires: https://www.gtoforum.com/conversations/17-wheels-tires.180064/

I ended up with Continental extreme contact sport 02. I won't be driving my car in snow and they supposedly have decent grip in wet weather. I don't have an close up pic of them but as far as tires go, they look good. Only drive with them for a few miles since they were out on, but handle very well and no road noise.

 

[ColoradoMike]

Very nice! Congrats!

The Firehawks handle well and are quiet enough, not that I can hear road noise over the exhaust. ;-D

Well, I have just ordered chrome-plated 15x10 rally 2s for the rear of my '69. I have a set of new springs for all four corners with a 1-inch lift. I plan on the 255s. The guy who had it before me had 275s on it, but it looked like the tire was going to pop off. 15x8s
