Anyone running 70 profile tyres on 15's ? Any pics ? I just want to get an idea of much taller they look as opposed to 50 or 60 profile tyres , many thanks

Part of this will depend on the width, but you can check on a website that has tire sizing like: https://tiresize.com/tyre-size-calculator/ to get an idea.  I think the 276 60 looks pretty tall at 28 inches total and the corresponding diameter in a 70 series would be 245.  (it would just be narrower).  I tend to like tires in the 27 inch range on 15 inch rims, but that is personal preference more than anything else.
Who in their right mind would say

"The science should not stand in the way of this."? 

Science is just observation and hypothesis.  Policy stands in the way.........

Or maybe it protects us. 

I suppose it depends on the specific case.....

I just picked up a set on Friday. Going with 215/70R15 for the front and 275/60R15 for the rear. Just the look I was looking for anyway. Not on the car. Here are a couple of pictures. I hope they help. That tire size comparison app is sweet. The dimensions are right on the money Mike!

profile number is not an absolute but relative number... is the % of the width making the height ( x 2 x 25.4 to get inches plus rim diameter )... so you can get same height with 225/70 than with 255/60 ( I'm just throwing out numbers, withouth making maths, but must be close )

70% of 225 milimeters width against 60% of 255 milimeters width

I understood that perfectly. I just never knew that!! Thanks for the enlightenment lol

well making the maths, numbers are very close on my example...

157.5 mm vs 153 mm, so around 1/3 of inch diff on total height being the 225 higher, but minimal... less than the 70% factor could tell you without really know what it means
