Year One snowflakes suck. They couldn't get the chinese kids to machine them like the originals.

I'm pretty happy with the YearOne Honeycombs I have especially for the price paid, just wish I could get a taller tire so my headers don't end up on the ground.

Thanks for the support 72

My Gramma car has the 17x9" Year One Rallys. I won them in the Year One contest several years ago.

I made the mistake of getting the 275/40x17 tires for the car and they are just too short in height at 25" tall. They just don't look right. I would like to get a 255/50 or 255/55x17 in the rear at least, to fill the wheel wells.

In addition, the 275/40s have the car reving at 2800 rpm at 60 mph. Too high for a 3 speed auto with 3.42 gears.

Here's the entire thread on the car.

I know what you mean, I have 285/40/17s on the back of mine they are 26 " tall and it's not enough either. The 255/50 would be 27" tall and at least some are being made. I don't think anyone is building a 255/55 so that is another size to lobby for. I'd like the 255/50s up front and 285/45 out back, but until they make some it's not an option.

26" is the stock tire diameter, and with correct ride height will fill the wheel wells. Also this is the diamter that your cars speedo was calculated on when new, and is part of your gear ratio..
I know this thread is about stance, but having tried a set of these, the ride sucked.
your 285 tire is 27.098 , that will change your rear gears to a taller gear ( lower number)
Your car in stock form set down in the back nearly 1 inch.....
have fun

For the early second gen Firebirds - 26" is the correct height (E78x14 - F60x15). But for the later second gens - 27.5" was the correct height (GR70x15).

My '64 GTO had an original tire height of 26.9", the '65 was 27.1".

Looking for a 27" tall tire for many of us gets us very close to original height.

That said - I think a 255/50/17 is an excellent option for most of us and is readily available from many tire manufacturers.

As far as the speedo being off with taller tires - you are assuming that the rear end still has the same gears.

I have the "correct" tire height on my '64 (27" tall 255/60/15's) but my speedo is off. The 3.42 geared 12 bolt posi vs the OE 3.23 geared 10 bolt posi is the culprit - not the tires.
