Tires Zr Vs R. So z tells us that the tire is prepared to speed above 149mph, and r tells us the tire has radial construction, which means the plies are constructed perpendicular to the direction of travel. A rating of "zr" means that the tire actually has a speed rating of z.

From memory, the z or zr bit relates to it being either a normal radial tyre (r) or there being some sort of manufacturer's added description about the way the load rating changes with. Obviously, most of these ratings are for tires that do not go on passenger cars. A rating of "zr" means that the tire actually has a speed rating of z.
This Zr Designation Was Established By The European Tires And Rim Technical Organization (Etrto).
So, zr can be categorized as a speed rating category. Zr tires include the v (149 mph), w (168 mph) and y (186 mph) categories. You will need to change the 40 profile to a 45 or 50 depending on how much lower your car is than stock.

I have been searching the internet for information but alot of it is very confusing. Zr or r found in: Originally, zr used to be a sort of category radial tire rating speeds over 149 mph.

It doesn't have anything to do with the speed. Before 1990, the manufacturers used zr to mean high performance tyres before the ratings got refined with w, y…. Zr basically means the tyre is adapted for speeds above 149 mph.
The "R" Actually Means That The Tire Is Radial;
This was first introduced for speed exceeding 149 mph. This was before tire ratings changed and we now have codes like v, w, and y. On the other hand, the r letter implies it has a radial structure.
For Instance, 245/45Zr17 91(Y) And 245/45R91(Y) Tires Have Same Capabilities For A Same Pattern.
Depending on where these letters are situated, they mean the former or the latter. Zr tyres includes the speed ratings v (149mph), w (168mph) and y (186mph). For information on how zr tires.
