A ''Z'' tire means that the top speed rating of the tire is not designated, and you must consult the manufacturer to obtain the rating. A ''W (ZR)'' tire's top speed rating is 270 km/h or 168MPH. A ''Y (ZR)'' tire's top speed rating is 300 km/h or 186 MPH. A ''ZR'' tire is rated at top speed of 300 km/h or 186 MPH, AND ABOVE. No, ''Z'' tires, and ''ZR'' tires are not the same.
A z rating on a tire is a speed rating, for most u.s. roads an h rated tire is fine, check with local tire dealer
It means it is a tire rated for 149 miles per hour. The Z stands for 149 mph and the R stands for radial.
Yes, it matters. Preferably each axle should have the same tires EXACTLY.
Not a singular "Z", but there are two: Zn- Zinc Zr- Zirconium.
The noble gas in the same period as Zr (Zirconium) is Kr (Krypton). Both Zr and Kr are in the fourth period of the periodic table.
Zr is from the Z and R in the word Zirconium. Zi would have been avoided due to possible confusion with Zinc, whose symbol is Zn.
It would all depend on the model such as zr, zl, z,firecat, or the new sno pros. Typically zl and zr will have about the same horsepower which will be around 80-100, a z will have much higher horsepower but much less speed, it will have around 100 at a mid to low. A firecat will depend on the year, in 2003 the firecats had 103 horsepower (more than any other year) but any other year would be in the same zr and zl range. And now finally the sno pro, this cat will have about the same zr, zl, and firecat range. I hope this answered your question. By the way, I'm only 12 but I spend hours talking with my dad about this stuff
The correct factory tire size for a 2014 Jeep Cherokee is 295/45 ZR 20.
Prior to 1991, tire speed ratings were shown inside the tire size, before the "R" character. The available codes were SR (112 mph, 180 km/h), HR (130 mph, 210 km/h), VR (in excess of 130 mph, 210 km/h) and ZR (in excess of 149 mph, 240 km/h). The ZR code is still in common use, often combined with a W or Y speed code.
i know that it is ..........
In the same period as Zr (Zirconium), the noble gas is Kr (Krypton). Both Zirconium and Krypton are in the fourth period of the periodic table.
MG ZR was created in 2001.
