Prince Edward Island Tire Regulations
Tire Size, Thread Depth, Width and Snow Chains Regulations (USA and Canada)
Tire chains are permissible. That’s all the law says about them. Studded tires are allowed from Oct. 1 to May 31. Studs should not protrude more than 3.2 mm or 1/8 inches in fraction beyond tire surface. The regulation also notes that studs should not be installed on used or worn tires. Between the period from October 1 in any one year and May 31 in the next ensuing year, it shall be permissible to use tires on a motor vehicle moved on the highway having on the periphery of the tire studs or protuberances of a material other than rubber but not more than five per cent of the surface of such a tire shall be of a material other than rubber, nor shall such studs or protuberances protrude more than 3.2 mm beyond the tread surface of a tire, provided further that no such studs or protuberances shall be inserted in used or worn tires.
