Wheels deviation
Hello!
I bought a 67 mustang 289 coupe and here in Romania, Europe i don't have technical literature at all, that is why i ask for your opinions. the car seems to be straight and looks like a show car. problem is that the front right wheel as well as the left back one are 1 inch outer than the others. (pardon my technical language). i checked the spacers and are equal, checked also the width of the rims and tyres and also are the same. I also measured the distance from the disk to the rim both on the left and right side and still equal. I managed even to measure the distance from the chassis to the rims and is the same on the left as on the right. so i can't find any reason.
please be kind and advice me where can be the problem.
Thanks

RE: Wheels deviation
Try measuring in an Xpatern around the car from underneath. Measure say..from the center of the axle mount on the leaf spring pad to the lower control arm bolt. Then measure from the transmission mount bolt to the lower ball joint. You may find some difference from side to side. This may show that although the car looks "straight" down the body the unibody may be tweaked out of square. Also measure from rear axle center tofront spindle on each sideand see if they are close with the wheels straight.
Also check the squareness of the underhood by measuring from corner to corner.
Everything should be within +- 1/2 inch or15 mm. If its WAY off that may be your problem

RE: Wheels deviation
Maybe backspacing. Switch the two front wheels and see if the problem switches sides. Do the same for the back. If the problem reverses, and the tires are the same size, put the wider looking ones in the back.

RE: Wheels deviation
post edited...I misread first time.
If 2 wheels stick out further on the same side...most likely someone rotated the tires on the car without confirming if the wheels where all the same size.
you need to measure:
Width of the wheels from lip to lip
Backspacing of the wheels from rear lip to mounting pad to determine if they are the same (or just put on one the front as recommended above).

RE: Wheels deviation
I will say that the two "narrow" wheels go in the front,,, and the two "wide" wheels belong in the back... (It could be the other way around but I doubt it)
It is common here in America to mismatch the front and back tires and wheels on modified cars.
So, I think your wheels are probably fine, they are probably just in the wrong place.... The spacing should be the same on both front wheels, and the same on both rear wheels.

RE: Wheels deviation
well, first thanks for the immediate answers and advice.
i think i will have to measure in x as blue66mustang said. wheels are correctly matched as i have 275 on the rear and 245 on the front.
Now i wonder which could be the possible reasons for this deviation ifx-measurement proves i don't have the right numbers. nand which would be the solutions. i will attach several images, maybe we can figure out some new ideas.
thanks

RE: Wheels deviation
Nice looking car!
Could it as simple as the tires are mounted on the wrong wheels?
Imagine that there were 4 wheels purchased identical to each other except that the offset is different on each pair of wheels front and back. If someone mis-mounted the tires onto the wrong rims, the tires could be in the "right" place.
I am 99.9% that the issue is with wheel offset. The car looks to be built way to well for it to be a stupid chassis mistake, even if this were to be reasonably possible, which it is not.

RE: Wheels deviation
well, i looked for the offset issue but it is not the cause. the wheels are Hot wheels sixty eight 17x9 all 4, with the same offset (lip). anyway i have noticed that on the front end using 9' wide rims is not the best solution as the upper ball joint is getting to touch the tyre ( the tyres are bf goodrich kdws 245/45/17)
so i guess we still have the dilemma. i attach here pics of the left and right front wheels to see the deviation.
please let's dig together and solve the issue.
thanks and i appreciate very much your efforts
