I screwed Woody's 18mm Twist Attack high-carbon core tire studs into my RZR 1000S to increase the winter grins and giggles factor, sliding and drifting.
Here is the deal with tire studs: you get what you pay for. Avoid the cheap look-alike knockoffs and get studs with a high-carbon core that are long-wearing. Woody's offers good value and they come in 11mm, 15mm, 18mm, and larger sizes for construction equipment. ATV and UTV applications are the 11mm, 15mm, and 18mm. Don't use the 11mm on a high horsepower machine. Remove the screws in the spring and reuse them again in subsequent winters.
