Can you patch a ZR rated tire?
Can tires rated H (130 m.p.h.), V (more than 130 m.p.h.) or Z (more than 149 m.p.h.) be safely repaired? Yes, with some reservations.

How do you read a tire size ZR?
The three-digit number is the tire’s section width in millimeters followed by the aspect ratio: sidewall height divided by section width. The following letter(s) describe the construction: R is for radial; ZR stands for a Z-rated radial (see service description); and ZRF means Z-rated run-flat (rare).
Does the Z matter in tire size?
SPEED RATING Z

What happens if you go faster than tire speed rating?
Running a tire at speeds higher than its rating can shorten the tire’s life and potentially lead to a tire damage which could result in an accident, so it is important to follow the manufacturer’s speed rating recommendations when you are choosing tires.
Are ZR tires good for winter?
NO, the rubber will be hard as a rock at low temp, and the rubber compound is hydrophobic, vs. hydrolphilic (I may have that reversed).

Are thinner or thicker tires better for snow?

Is it better to have flatter tires in snow?
If the snow is just a couple of inches deep, you’ll usually do better with a normally inflated, narrower tire, which can bite through the snow down to the pavement, where the tire can get some real traction. That’s why snow tires are often narrower than all- season or summer tires.
