is my math correct?

They make a 28”.. 17” m&h drag radial 325/45/17 sidewall is 5.8”


The 28” Mickey T on the 15” rim is a 325/50/15 sidewall is 6.4”

So it’s .6 “ of an inch more sidewall..on a 15" rim…better off just getting the 17” tire right? Instead of going to 15’s etc?

Sidewall is 2nd number is a % of the first in millimeters right..ie 325 x .45 = 146.25 mm..to inches is 5.8….right?

I mean I was going to get weld rt-s etc. but all that just for about a half inch more? Doesnt seem worth it when I can put these on my 17x10.5s cobra rims now.

15" will hook better because of the extra sidewall and will be easier on your car. No matter if you have an IRS or a Solid Axle.
