I am going to attempt to attach some pics before and after the new wheels and tires. The new wheels are American Racing T71R. Fronts are 17x8 with 4" BS. Rear are 17x9 with 5" BS. Tires are Nitto 555. Fronts are 255/45/17 and rear are 285/40/17. They fit with no issues. I am stoked at how they look on the car.

No big surprise here.

My 69 GTO has the standard 14x6 Rally IIs all the way around.

No problems with P225/70s on them.

Rarely, with 5 people in the car and hitting a decent bump at higher speeds, a quick bottom out has occured. (I plan to stuff drag bags in to maintain more height and correct this- it spends its time taking the kids out for ice cream, etc. and not at car shows or the drag strip)

I think they are a great tire up front.

I want a little more height and width in back.

I am refurbishing a pair a HM code 15x7s for the rear.
Plan to 255/70,
275/60,
or, if can find, 265/65 and see how it works.
(Goal- slightly increased diameter to decrease rpms while crusing, and a touch more raise to the rear end, and a little wider tire than the 225s.)

Here are the
225/70 14s all the way around.

If that the end goal, you might just want to go with 255/60r-15s which are 27" tall(slightly taller that 26.8 of the 225/70/14) and would work great on the 7" wheel.

a 275/60/15 is pretty big.

If the tire shop has both, see if they will test fit them on the car to see if it's the look/profile you desire and go that route.

Ok, I went from 14x6 Rally IIs all the way around with p22570s.
I kept those up front.
I restored a pair of 15x7 Rally IIs (take that green party and cash for clunkers, how many of them have keep 4000 or so pounds of vehicle and parts out of the scrap yard. We are the damn environmentalists, not them. There batteries filling land fills will be the end of the environment some day.)

the PMD caps are not fitting the 15x7s tight, so the arrowhead caps they came with are on for now.

I went with R15 p275/60s. A classic look for muscle in my opinion is taller, wider, and a little more sidewall in the rear compared to the front. You gain about 1.5 inches in diameter/ .75 in height, 1.8 inches in width, and .25 inches of sidewall in the rear compared to the front in this combo on these rim sizes.

Just the look I was going for, plus a couple hundred less rpms at cruising speed.
Have not had the wife, spare, and all the kids in the trunk, and hit bumps at speed, but think I am going to be OK.

My "Day Two" look I was going for is complete.
You can compare to my sig for the tire size appearance comparsion.

I know the hood scoops, hood tach, and spoiler are suppossed to be body color.
I know it is supposed to be 14 inch rims all around, no trim rings, and PMD caps in back (which if I get them to fit tight will put on),

I know it is not supposed to have "GTO 400 CID" gloss black stickers and gloss black The Judge stickers on the spoiler, extra stickers on the rear window, the split exhaust tips, etc.
should be a blacked out front grill, etc.
Not going for a factory correct show appearance. Going for the look you had in the 70s and 80s when you got your hands on one.















these are not balloons, these are how old school muscle looks







ok, maybe I do need hood pins,
but that will be the last thing for appearance. I swear.

Thats is a great look.

Front and rear springs were replaced in 1987 (front cut about 1/2 turn) and Koni red.

Currently looking at a set of Year One 17x9 gold snowflakes (not sure of tire size yet but definitely open for suggestions).

Sorry if this is a double post.

Nothing rubbs ever but I want to put 17" or 18" wheels on as soon as somebody makes RWL tires for them.Then I can put on some BIG brakes.

[Z Code 400]

I wanted to keep the 'traditional' look on my Formula with the period-correct 15" tires. I also wanted the ability to rotate my tires, so it was important for me to keep them the same size at all four corners. I went with a Corvette Rallye Wheel because they were cheap, could be ordered with any offset I wanted and would allow me to run the correct size tire/wheel combination until the car was finsihed and I could move up to Centerlines in the same sizing.

Whells are 15"x8" with 4.0" backspacing. Tires are 255/60/15's all the way around. I will be cutting 1 full coil off the front springs when I swap in the tubular upper and lower control arms to drop the nose down just a little...Robert

I am with nkowi. I also added tubular upper control arms, poly bushings on stabilizer bars, solid body bushings, sub frame connectors, stiffer and lower springs, 17" rims (though not ghetto), 6-piston front and 4-piston rear discs with 12" slotted and drilled rotors, closer ratio and stiffer valved steering box.....

For me it is about handling. I love the original look of my car, hate its original handling characteristics.

I do however also like the look of "67 LeMans 326" car. I would like to know the brake set up that fits under the 14x6 inch rims.

Here's my car with new wheels and tires which are Foose Legends, fronts are 17 x 8 with 4.25 bs and the rears are 17 x 9 with 5.25 bs, and the tires are Nitto 450's 255/50/on front and 275/50 on the back. I have dropped the front about an inch or so.

I have 17" wheels. 7" up front, 9.5" out back. 225 tires up front, with 325 out back.

i'm gonna mess with lowering and bigger tires in the back after paint, but this will give an idea. Rims are 17x8 and tires are sport maxx 245/45/17
