I know that you are talking about installing 2 snow tires and worry about liability....

About couple weeks ago I saw a good deal of a set of snow tire, I've emailed ICBC about liability of downsizing too much.

Original: 205/55/16
New:195/55/15
(speedometer would show about 5.8% too fast.)

here is their reply:

Your Autoplan coverage would still be valid in the event of a claim, but the difference in size could affect how fault is determined.

You could also be subject to possible motor vehicle fines if you don't meet the requirements set out in Divisions 7.161 and 7.162 of the Motor Vehicle Act Regulations; you can find unofficial versions of these divisions on the Queen's Printer's website at http://www.bclaws.ca/Recon/docum ... 04.xml#section7.161

Please let me know if you have any further questions.

at the end, I bought 195/65/15
