Please list the following for your car..

Year Make Model

Tire size
Wheel width and offset
Lowering amount, if any
Rubbing issues experienced, if any
Any other pertinent info you think might be of use to us (ex- I have air shocks in the back so nothing rubs, you get the idea)

OK, question time:
What are the largest tires that will fit our cars out back, when plus-sizing?
I am looking for a 17" tire, but I want something in the range of a 275 series, around a 30" tall. I want to say there is a 275/60r17 on General's site in the grabber UHP series.
I also saw a 255 tire...but at 27" tall, too short for my taste for back tires.
 
I looked at the typical Mustang type 275/40r17, and forget it, I don't want a donut 25" tall tire. I need some sidewall!

What's the overall hight on that tire? My concern with the 50 series, it may be too wide for the 8" rim width.

I am looking for original size white wall tires for my wagon. I have a 1975 Gran Torino Wagon. What would yall recommend?

P205 75 14's, P215 75 14's, or something else?
 
I'm not looking for a bigger wheel combo as I am wanting to keep my original Torino hub caps.
 
Thanks, Carlos

On a wagon, I would of thought by 1975 they would have been a 15" rim.
On that car, i would think the tire size should be around a 225/75 or a 235/75 series size tire.
205 and 215 seem entirely too small for the weight of a Wagon, let alone a 4 door or coupe.
You can still run a bit of a tire on a 14" rim, but the sizes are getting increasingly a pain to find.
I forget, but I would image a 225/60 will fit a 7" wide rim?
Or, at the wheels you have a 14x6?

According to Coker Tires website it states the 1975 Wagon had size HR78-14 tires. Isn't this a bias ply tire??? Can someone tell me what this translates to when it comes to radial tires???

This was something I found poking around the net with Google...I think this would apply well with our Heavy Torinos.
From what I gather, you should stick at least a 225/75/R14 tire on your car.
If I was you, I would upgrade to Ford 15"x7" steel wheels, and go to a 235/75/r15 for a larger stock Torino sized tire that a lot of cars had. Every Elite I have owned were factory 15" wheel cars.
The Gran Torino Sports I have owned have all had 14x8 wheels, I have some 14x8 factory steel rims That I have held onto a few as spares with original bias Goodyear or Firestone tires because I like the look of the old tires.
 
Remember, you have a wagon. That car has some serious heft to it.
If you want to stick a whitewall on there, stick with a good brand...you are going to spend twice for white walls versus a blackwall or raised white letter, judging by the Coker Classic line of wide white walls, but BFG would be another good choice.
I figure you will have $900 for 4 tires, $1,125 for 4 plus the spare, and that's not including the shipping.
I would tell you to check out a local you-pull it for a 80's crown vic, those wheels should still accept the Torino center cap if the rim's center has the bumps for retaining the cap.
 
If you wanted to get fancy, I have a set of the Elite specific slotted stainless steel hubcaps, but you would need a 15" rim.
  
 
This bit came off here:
 

The first number is the width of the tire in millimeters, measured from sidewall to sidewall. To convert to inches, divide by 25.4 In the example above, the width is 185mm or 7.28".

The second number is the aspect ratio. This is a ratio of sidewall height (also referred to as "section height" in the diagram) to width. In the example above, the tire is 7.28" wide, multiply that by the aspect ratio to find the height of one sidewall. In this case, 185x0.60=111mm or 7.28"x0.60=4.36".

The last number is the diameter of the wheel in inches.

To figure the outside diameter of a tire, take the sidewall height and multiply by 2, (remember that the diameter is made up of 2 sidewalls, the one above the wheel, and the one below the wheel) and add the diameter of the wheel to get your answer.

Example...185/60R14 85H or 185/60HR14

185mm x .60=111mm x 2=222mm + 355.6mm(14")= 577.6mm or 22.74"


Tips from Dick on How To Calculate Your Tire Size:

Here is how you figure out the dimensions on a tire and what will work for your car. The first number is the width in Millimeters "255" is 255 mm, or about 10". I don't know what year your car is, but chances are these tires will be at least 1" and maybe almost 2" wider. You'll have to look to see if you have clearance, between the fender skirt and the rear wheel, and between the frame and the inside of the front tire in a sharp turn. Remember when you hit a bump in a turn, the tire will move a little closer to the frame.

The second number is the percentage relation between the height from the rim to the road as compared to the width. "70" means the tire is 70% as high as it is wide, or 7 inches from rim to tread (with no load on the tire). This will be a short, fat looking tire for your car, when the original was a tall thin dude. Some like this new look, some don't. You pick it.


Tips from Chris on Tire Measurement:

The measurement of the sidewall height on tires is always done as a function (or percentage) of the section width, and it's called the "aspect ratio."

In the 1950s and early 1960s, the standard aspect ratio was 82-84%, meaning the distance from the top edge of the rim to the top of the tire tread was that percentage of the width of the tire (which is measured about mid-carcass, not at the tread). Tire sizes were usually given as simply the section width and rim size, like 9.15-15 (9.15 inches wide, 15-inch rim).

Around 1970, bias-ply tires moved to a 78% aspect ratio, this the term "H78-15. H was a load rating, 78 was the aspect ratio, 15 the rim size. All tires using the same load rating (for example, G70-15, G60-15, etc.) were the same diameter. Because the diameter was the same and the aspect ratio was lower, a 60-series tire was wider than a 78-series.

As radials became the norm, these designations stayed in use, but an R (for radial, of course) was added: HR78-15. In the 1970s, US tire manufacturers adopted the European system of metric sizing (though the rim diameter is still in inches). Example: 235/75R15. R still stands for Radial, 235mm is the section width, 75 the aspect ratio, 15 the rim diameter. What's different in this system is that the section width is an absolute number, so a 235/75 is just as wide as a 235/60. The 60-series tire is therefore smaller in diameter.

During this time period, the "standard" aspect ratio dropped to 75% (today, 65%, 60% and even down to 35% on some exotic sports cars, are all common).

So, if you wanted to put a set of radial tires on an old car and approximate the original sidewall height, you'd have to go with an enormously wide tire, which is undesirable for many reasons, including more difficult steering and some odd handling response (for these cars, which were not designed to have such a big contact patch between rubber and road).

As such, we compromise with a balance of width and height that comes closest overall... an old 9.15-15 might become a slightly wider but shorter HR78-15, which then becomes an even shorter 235/75R15.

Finding correct-size 14-inch tires today is harder still, because few tire manufacturers make little 14's strong enough and wide enough to manage the load of a 5,000-lb car. Choose carefully, note the load rating (remember, some 65% of your car's weight is on the front wheels) and the temperature grade (B is OK, A is better, C is not good enough), and maintain proper tire pressure (about 4 lbs below max is what I use). We've all seen what happens when under-inflated tires overheat in a heavy vehicle like, oh, I dunno... a Ford Explorer?

Question:  I have a chance on a good deal for a NICE set of torque thrust wheels.  Dimensions and offsets are:
 
Front:  18x9 wheels  4" offset  245/40/18  9.65" wide x 25.72 high
 
Rear:  18x10 wheels  6" offset  285/35/18 (worn should be replaced)  11.22"w  x  25.85" Tall
 
Question is, it looks like these should fit EXCEPT I am not sure about the 6" offset on the rears with this setup.  I could always go a little skinier on the rear but with the 6" offset I am not sure
 
The fronts sound like they would fit, but tight.  Opinions?  I could probably put the fronts on the rear rims and get skinnier on the fronts, but I want to make sure I am not wasting my money...
Thanks!

THanks, my concern was especially with the rears and the huge offset.  I was not convinced, but it was a pretty damn good deal. 
I will pass on that deal, thanks for the advice.  Most of my looking has baan in the 15" & 16" range.  Congrats on your wheel deal!

Hey, I may live in NH, but even I don't walk around carrying a shotgun in the front yard! LOL
So, 15x10 with a 4.5" or 5" offset will fit under our wells without modification?  Good to know.
Looks like I will be sticking with 15x9 or 15x10 for the rears when I finally get there.  The car will be dropped a little and I now believe it will fill out the wells nicely when it's complete.

Something from a recent email I sent to Crager's tech email:


Both the 17x9 and 17x8 are 0 offset.  The 17x8 is 4.5” and the 17x9 is 5.0”. 

 

Thanks,

Jeff-

Thank you for the info on that, I just did not want to assume before I order a set of wheels from Summit Racing.

One more question, on the 17" wheels, are any made with a neutral offset?

I am mainly looking for wheels that, for all intense purposes are as an example 17x8, with a true 4" offset, or in the case of the 17x9, a 4.5" offset so the wheel is on the center line of the hub mount surface.

 

Thank you,

 

Andrew

 

 

 

 

In a message dated 11/10/2009 2:23:26 P.M. Central Standard Time, jeffdanbom@cragar.com writes:

If a wheel is called a 15x8, it measures 9" wide, likewise a 15x9 will
measure 10" wide.  The measurement is from bead to bead, which is 1/2"
from the outer lip on both sides.

Hello-
I am looking for the exact specs on the wheel dimensions for
part#345-8912, I need to confirm the actual measurements for this wheel
but do not find anything posted online.
I am looking to see if the overall width is 9", or if that is the width
of the bead area from inside to inside edge.
Thank you
Andrew

post a picture of that!
jack it up from the center of the diff, mount the rim and take some pics of just the rim on it.
Some shots with yard stick to show the measurements.
 
THAT would greatly help us all.

Here you go...
Pumped air shocks all the way up!
 
275/60/15 rear on 15x7 rims, tire is 27.5" tall, fender sits at 29"
225/70/14 front on 14x7 rims, tire is 25.25"tall, fender sits at 26"
 
NOW... added the 295/50/15 tires on the 15x10 rims (3.5" backspacing)
Tire is 26" tall with fender sitting at 28.5"
You can see the tire sticks out and leaves alot of room to the frame.
NOW I dropped all the air out of the shocks to change the rake...
They RUB! Disregard the measurement card. The fender sits almost ON the tire!
 
 
Leave the 295/50/15(15x10rim) on the rear AND put the same on the FRONT!
Pumped the shocks back up for these.
With this combo it rubbed the front and rear of the front fender.
A small adjustment to the backspace would make it clear (MAYBE)
But damn it looks badass! NASCAR/MADMAX style like a bulldog that says DO NOT F**K WITH ME!
Here's the pics of the 295 on the front rubbing and rear clearance
 
Dropped the air pressure out of the shocks with the 295s on front and rear...
WOW THAT HAS A COOL FLAT STANCE!!!
Forgot that pic!!! Angry
 
Here's the PLAY with the rear wheel...
These are with the Airshocks pumped back up all the way.
Turned the rim around so instead of a 3.5" backspace it had 6.5"
With a 1/4" spacer it would bolt up without touching the rim cone to the drum.
With a 1" spacer it would clear everything at the frame and still be tucked inside the fender.
So I THINK a 4"-5" back space would put the tire and rim in the right place.
 
Clearance is TIGHT with the 6.5" backspace...
Wheel is tucked in...
Dropped all the air out of the shocks and it almost looks like it is tubbed...
 
So there are my Tire adventrues for the day!
 
MY decision...
295/50/15 on the back with a 15x10 rim have to decide on the backspace most likely 5" so it sits right inside the fender lip after I roll the lip under and smoothe the sharp edges.
255/60/15 OR 255/70/15 on the front with a 15x8 rim and then play with backspace to fit it in.
Have to put both under the fender and see what looks right, I am thinking the 255/60 is the right one!

Yes, they are the rims I got from Brent in AZ.
I am not going to use them, will definately sell them to you. PM Me, I will look through my PM's find out what I paid total with shipping and that is what I'll sell them for plus shipping.
 
I saw the post that someone had 15x10 with the deeper backspace and 295/50/15 as well... REALLY WANT TO SEE THOSE PICS!!!
 
I am going to order a cheap set of steel wheels just to use for fit and measurements during the restoration/build.
