Hello All,
Building a 1941 Ford Pickup. Mustang II Front End and 1967-70 Mustang 8" Rear End (has same WMS to WMS dimension as stock pickup = 59.25")

Wondering what front and rear wheel size (including backspacing) and tire sizes any of you may be running who have the same or similar setup.?

Thank you

I'm willing to bet you'd get a lot more useful advice over on the HAMB site. A few of the Barn guys dabble with modified cars but the HAMB??? nearly all of them do.

Well, the HAMB is a better place but you will not get a warm reception from many as it is more of a traditional or traditionally style site. So, MIi suspensions are not really traditional.

But, there are some of us here who have built/owned cars like you describe . Built a 40 coupe, 4” dropped axle, reversed eye front spring, used the Speedway 4 bar setup, and 14x6” Rim’s with 4” backspace and 195/75-r14 tires. Out back, Chassis Engineering parallel leaf kit, lowering blocks, 8” rear, 15” x8” rims with 4” backspace, 235/75-r15” tires. Car sat low, had clearance, and used Chasais Eng front and rear sway bars. I will post a pic for you tomorrow ....

Regardless, good luck ....

41-pickup, just a note to say, I PM'ed you a message about
some 15" x 5" Ford wheels with 4.5" bolt circle that I have, thx

Since you are changing the front end to mustang type front clip and a later model differential you will have to use Ford passenger car lug bolt pattern wheels, front and rear. Make sure the wheels for the front will work on disk brakes.
You will probably need 6.5" wheels on the front, the tire size will depend on if you want a somewhat stock look, or the big/little street rod look.
My taste runs towards same size tires front and rear... P205/75-15 front/rear would work well.. The rear wheel back spacing depends on the axle width..
My advise would be to get the chassis all assembled and the body sitting on it before you go out and purchase wheels/tires.

Wheels and tires are the LAST thing you buy for your project. Wait until the pickup is completely assembled and then take your measurements for wheels and backspacing. If you have the large disc brakes on the front you need to have a 15" wheel for clearance. I would definitely stay away from 14" wheels as the tires are harder to get and the variety of sizes has dwindled.

Also, '49-'66 (or so) Ford Car wheels had a 2 3/8" center hole, but the
wheels you need, will have to have the bigger 2 3/4" center hole that
Ford Cars started using in the late 60's and newer.
