7R Spring Plate Clearance

I have finally fitted my custom 16 x 7R wheels and tires to the rear of my 71 hot rod. This is a stock narrow body with stock flares.

My previous tires were 225x50x15 on 7R x 15 fuchs and they fit fine.
Even though the new tires are about an inch taller, they seem to fit well with no fender rubbing or bottoming on hard dips.

I have the Elephant racing spacer kit on the back so have a wide range of adjustment available.

The 7R x 15 set up used 13 mm of spacers on each side.

With the new 7r x 16 set up I reduced the number of spacers to 11 mm. There is about 1/4 to 3/8 inch clearance to the spring plate bolts and at 2-3 mm to the fender lips (the lips are not rolled.

So far so good.

However, does the clearance I have stated above seem adequate to those with familiarity with these fitments? In other words will the .25 inch spring plate to tire be adequate?

Thanks in advance
Dan

Danimal is forgetting that it's only 1/2" from the center to the rim.
