hello everyone I'm finally upgrading to a 16inch rim with my 5 lug upgrade and now trying to figure out the best size tire for my new rim size. I'm stock width with stock sized 16 inch rims I believe they are 6 or 7 inch wide whatever ford stock size it anyway when I put in the new rim size online they gave me a bunch of options on what tire sizes would fit so now I'm at a loss. I've seen one fox with 225/55r16 and it looked good but idk if that fox was lowered or not and my fox is factory height so idk if I should go with the 245/50r16 as that would give me a slightly taller side wall but then again if the fox I saw with the 225/55r16 was in fact at stock height then 225s would be best. Can yall post your photos of your mustangs with 16in rims in here and list the tire size your running and note if your fox is lowered or stock height. Thanks

The stock pony rims are 16 × 7 F & R. Increasing the sidewall height will of course reduce the gap between the fender lip & tire.It gets reduced even more as you increase wheel diameter, which gives you the added benefit of reducing the gap while running a tire with a shorter sidewall height vs having to use a tire with a much taller height in an attempt to fill the gap,which can sometimes look tacky. I made the following chart to list the width & height of various tire sizes. The pony wheels look great with a lowered stance vs using a tall tire to fill the gap.




(TIRE WIDTH SIDEWALL HEIGHT CHART)


***** 50 SERIES *****

(215-50-16)
W= 8.46"
H= 4.23"

(225-50-16)
W= 8.86"
H= 4.43"

(235-50-16)
W= 9.25"
H= 4.63"

(245-50-16)
W= 9.65"
H= 4.83"

(255-50-16)
W= 10.04"
H= 5.02"


***** 55 SERIES *****

(215-55-16)
W= 8.46"
H= 4.65"

(225-55-16)
W= 8.86"
H= 4.87"

(235-55-16)
W= 9.25"
H= 5.09"

(245-55-16)
W= 9.65"
H= 5.30"


***** 60 SERIES *****

(205-60-16)
W= 8.07"
H= 4.84"

(215-60-16)
W= 8.46"
H= 5.07"

(225-60-16)
W= 8.86"
H= 5.32"

(235-60-16)
W= 9.25"
H= 5.55"

(245-60-16)
W= 9.65"
H= 5.79"

(255-60-16)
W= 10.04"
H= 6.02"


As an example of why a 1" increase in wheel diameter works,the two images at the bottom (source: LMR) are with 17" pony wheels,F= 245-45-17 R= 275-40-17 tires.Lowering springs arent even required to close the gap.To reduce the gap 1" using solely the tires sidewall height to do so,you would have to move up 4 tire sizes to accomplish the same task. IOW- you'd have to jump from a 205-60-16 to a 245-60-16 to gain 1" in tire height,to reduce the gap by that same 1" a 17" wheel would accomplish.
205-60-16= 4.84" sidewall height
245-60-16= 5.79" sidewall height

** BTW ** Example: 245-60-16

(245)
The first number set on a tire= tires width in mm. Divide this number by 25.4 to give you the tires width in inches (245÷25.4= 9.65")

(60)
The second number set= tire sidewall height or aspect ratio.This is a % of the tire width.
Multiply the tire width by this number to give you the tire sidewall height (9.65×.60= 5.79")

(16)
The third number set= tire diameter

Stock Ride Height
Front:
215/55R16
+4 Offset

Rear
245/50R16 (Same Diam as stock 225/60 R15)
+4 Offset

Ill get you a pic tomorrow if you need or you can take a look at the video i posted here: https://www.allfordmustangs.com/forums/5-0l-talk/1087447-finally-runs.html

+4 is a less than ideal offset but you can make it work.

No rubbing as of yet and the fenders are not rolled

So idk how your +4 offset compares to my 25mm offset if i did the math correct i believe that makes my offset in inches +1.3? So that would make my rims sit a lot nicer inside the wheel well vs your setup correct? Idk if I want to do 2 different tire sizes front and rear. Cant rotate directional tires with different sizes. Is the reason you went different sizes for fitment in wheel well or for the skinnier front tire look? Could I go with the rear tire size on all 4 seeing how I have a better offset rim?

Yes your rim would be tucked back more.A +4mm offset would mean the hub mounting surface is positioned 4mm past the centerline of the wheel or 4mm closer to the front of the rim.
If the rim has no tire and you view the rim by setting it on the ground in front of you to where you can roll the rim towards or away from you,a zero offset means the hub mounting surface is positioned in the very middle of the rim.If the rim has a + positive offset,the hub surface is positioned closer to the face of the rim.If it has a - negative offset,the hub surface is positioned closer to the backside of the rim.So Krem12's rim's hub is sitting 4mm past the centerline, closer to the rim face.Your rim's hub is sitting 25mm past the centerline,closer to the rim face.
If your rims and his rims are the same width,more of your rim will be tucked back inside the wheelwell than his.The following diagram can be used.

This is good stuff. A fox "style" offset is totally the way to go. alot less fingernail biting worrying if the wheels will fit the fenders.
