55 -59 Front tire size

[Rods57]

I am looking for tire size info for my 57. I want to fill the fenders and have a 78 front clip, stock springs and spindles. I have a set of 235/75/15 with 8' wheels and 4' back spacing. they fit but I know it will settle over time. anyone ever seen that big up front work? Thanks for any info

The wheel placement makes a difference as to how a certain tire size looks in the fender opening. I am using a 225/70-15 on my truck and have the wheel one inch forward of stock. I am considering using a 235/75-15 later on, but it may look a little too far forward in the wheel opening. I am using a 29.7" tall rear tire (265/70-15) and the frame sits on a 2 degree rake angle. It looks like you have a real nice front clip there. Do you know where your centerline wound up? Hope this helps.

Here's what it looks like with no motor and 205/75/15 not sure what to measure to get the center line? My biggest concern is that they will rub on the fenders.

From my experience it's not possible to get an 8" wheel under a clip using the stock control arms. The only way I could get a 7" was by using the 80's Camaro style wheel with positive offset, like they're almost flat. I hated the look so ended up with shorter control arms and it's still close. Goes straight fine.....no turn. The down side of a Camaro clip.

Thanks for the advise, I found a guy with a truck locally that will let me experiment to see what they do on his. will probably go to a 225 or 215 on a 6 or 7.

I'm running a 235/60x15 on an 8in wheel with 4in of bs with no issues.

Not really applicable to your set up but I have run 7.50 x 16 in 2 and 4wd configuration. Then switched to 265/70 x 16's. They have 8" tread width and 29" height. here is a pic.

Guess I should have included the caveat about ride ht. Sitting at or near stock ht. you won't have a problem. If you're a weed burner, you will.

What about with the 70s power steering box kits? What can you run?

I have 235/75/15 Cokers on eight inch Corvette rally wheels with four inch back spacing. I have the Chevy frame mounted box and have about 1/8th to 3/16th inches of clearance with my wheels turned to the right limit. My truck is not lowered but my front springs are tired so it is a couple of inches lower than original. I think I remember reading that my CPP disk brake kit did move the wheels out slightly, which would help this clearance, but yours is probably the same.

Thanks, your looks like its about the same height that I am going for too.

Not a weed burner, but is lower than stock.

Hey thanks for all the responses, I am testing it on a truck this weekend.

I have a Mustang II front end, and a 79 Firebird rear.....the truck has 225/70/15s on a 6" standard wheel up front, and 255/70/15 on a 8" standard wheel in the rear.....has a nice rake and the tall sidewalls help the ride, tons!

I did my Camaro sub frame the same as yours, but I have 2” drop spindles and I moved the wheel base by 3/4". I flipped the Camaro rear axle on the factory spring pack. All the tires are the same 235/60/16. My rims are also 8” with a 4” back space.
