Pictures of 325/50/15's mounted on 15x10's with 5.5 backspacing.  I don't have as much room as MeFirst has on the spring side, still looks to be plenty.  I saw Tom's picture of his car and had to try it.  This is one bad ass looking tire size on the back of a Charger.  Is anyone running 295/60/15's.

Is anyone running 295/60/15's.

Here is a pic of the MT 295/65/15's on a 15x10 Weld ProStar wheel & SS springs. These are 1.5in taller than your 325's and very close on the section width.

[khodne]

They sure look nice Ron.

[khodne]

What BS did you use?  With my 5.5 with anymore width I'm afraid it would rub.

[firefighter3931]

They sure look nice Ron.

Thanks, i really like these tires...they hook like a slick when you heat them up ! 

What BS did you use?  With my 5.5 with anymore width I'm afraid it would rub.

Mine are also 5.5 backspace but they were too tight to the leafsprings. I used a 1/2in billet wheel spacer to move them out for the additional spring clearance. In my case a 5in backspace would have been perfect.

hey khodne,can i get a pic of the side of the car,with theese wheels and tires? also do you think a 5" backspace would work good for this tire size?thanks

ron i never get tired of seeing pics of your car,beautyful..... 68 chargers are my favorite...thats why i have one too 

[khodne]

I think this is what you were asking for:  Picture 1 from the side, Picture 2 from the back, and Picture 3 is from the front.

I think Ron is correct, 5" BS would be ideal.  5.5" BS is a little closer to the springs than I would like.

[bull]

Nice! The wheels look good too.

[Musicman]

5" +/- seems to be about right for most 1st & 2nd Gen's when using 10" rims...
Like Ron, I measured mine first and found that a 5" BS would have been perfect, but ordered them slightly over (5.25 BS) just to be safe, and then shimmed them out as necessary to center. Better safe than sorry when ordering a custom backspace...
I cut my own shims on a Water Jet...

[bull]

I'm guessing you can't use standard wheel studs if you're doing any shimming though, right?

[Musicman]

Depends on a lot of things really (shim thickness, rim style, etc)... there are a lot of options out there today (thick spacers with studs attached, long shank lug nuts, etc).

In my case however, I really had no choice but to move up to a 3" stud front & rear, due to the thickness of the racing style hub on my Cragars. Actually I installed the full 3" Moroso set on the front, then cut a set of Moroso's back to 2-3/4" for use on the rear.

[john108]

It seems that many of you use 15 x 10 inch rims on the rear.
What size rim and tires do you use on the front?

[mikesbbody]

Pretty much any size you want within reason of course. The more common sizes for 15's on the front are 235-245 60/15's on a 7 inch rim some guy's go wider some guy's go for more narrow tires on the front it comes down to what you want and the look you want. 

[Musicman]

Myself, I have 235/60/15"s mounted on 8" rims 

[Mefirst]

I run 185/75-15 front tires They do look like bicycle wheels. I do have another set that are 225/60-15

As already mentiond I run 325/50 tires in the rear on 10" rims with 5" backspacing, perfect fit.

I may have to go up in diameter on the rear tires, this because my new rear axel has 4.56:1 gears, with a 28" tire that might be a little to much.. Need to try it out and see how it works out... or not...

Hey Khodne, do you have superstock springs on your car?

[Hemidog]

Let me know if you want to get rid of those tires Tom! (and they have some thread left  )
Impossible to get a hold of 325/50-15 tires in this country.

What 325/50-15 tire has the best thread pattern for the street? Nitto?

[khodne]

I have the stock springs that came on the car.

[Joshs68]

I have 325-50-15's on my car. I use a 15x10 with 4.75"backspacing. I tried my first set from wheel vintiques they were 5.5" backspacing. Very obvious they would not work. wheel vintiques argued with me, said they fit. I sent them back and got the 4.75" a 4.5~5.0" will work. I split the difference, they were special order but no extra charge. I don't have pics on this computer but I have posted in the wheel and tire section before and posted pics.

I know this is a really old thread, but were there any modifications you had to make? Is the outer lip even rolled?

Again, i apologize for responding to a really old thread, but do you have any pics you could post with the 325/50r15?

I believe that is all stock/factory.  That is about as big of a tire as you can run without getting into some fabrication work.  I run 295s with no issue...

Yep 325-50-15 is as large as you can go with stock wheel wells.

But you had told me you rolled the lip, correct? Was that necessary or do you think it could have fit without rolling it?

it has to be rolled, it is still stock, as no cutting or replacement wheel wells.

Ok thank you, what backspace are you running? Is it 5" like everyone else has said works? Also, when you rolled it, did you keep the chrome trim on while doing it? Or did you have to take it off?

4 7/8 bs,,left the trim on.

[c00nhunterjoe]

I will have to measure my wheels and then post pics to play... im running a 30" tall tire on a 10" wheel with no problems.

[nickstev440]

4 7/8 bs,,left the trim on.

My final question (i promise lol sorry), is what is your axle flange offset, as the stock is 2.36, correct? I plan on going with the Moser rear end, which comes with the 2.5 ofset, and since these tires can be pretty close every 1/10" counts. Im just making sure it would still all work, however I'm assuming you have more than .14" of clearance

I ordered mine from DrDiff, it is a Strange brand, Cass @ dr diff is a MOPAR person, he knows what works, Obviously it is a stock offset, or I would have some serious problems, if you dont listen to anything else, get your set up from DrDiff

Serious problems? Just to make sure were on the same page I mean the flange to housing offset (brake gap, brake offset, whatever its technically called), I wasnt referring the axle length offset/pinion offset.

my set up is stock for 68 b body, disc brake rotors are thicker on the face than drums, so it moves the wheel out more than drum brakes, I am running rear drums.

[nickstev440]

Looks like the Weld Racing wheels I was looking at don't offer custom backspacing, so I will be getting 5.5" and use a 3/8" spacer, to get 5 1/8" backspacing, because the discs push it out 1/8", the only other problem would be the brake gap (axle flange offset, whatever it's called), would also push it out an additional .14", although, based on PM's with MeFirst, I should still have enough room, worst case scenario I'd have to swap out the 3/8" spacers for 1/4".

[nickstev440]

Is there a reason alot of people that talk about their times have tires that aren't as wide? How much does the width of the tire affect strip times? Would 325/50r15 be too wide (ignoring fitment)?

Not all cars are the same, my car is a street car, I run a DOT street Drag Radial, my car needs ALL the tire I have, if I was running a Drag slick it could be a smaller tire. a 12.00 sec car should not need the size tire I run.

The bottom line is traction. Wider tire equals more pavement contact which gives more traction. I run an extremely skinny rear tire just because i want to see how fast can i get my car on essentially the stock width tire. I essentially run a 225 tire on the back of my car and the goal is to dip into the 9s in the 1/4 mile on stock suspension. If i run a wider tire, i can launch it harder, but everyone runs big tires and i want the bragging rights to be as fast as a tubbed car on a little baby tire.

yeah but f.a.s.t cars have insane internal modifications. Still impressive what they are doing on stock appearing cars. Hemijoel is one of my favorites. Their engines have more modifications done then nhra stock amd cost more as well. Big strokers and unlimited head porting makes the power. Highly reccomend watching them at your local track if anyone has never seen them. But dont be fooled, they are NOT stock, they just look like it. Factory stock is another cool class to look into to that dave runs. Reminds you of the old school nhra days.
