I live in Montreal, QC and we have a mandatory Winter Tire Law which is slightly annoying but overall a good thing.
I bought my tires off tirerack.com and had them shipped to a business at the border in Champlain NY. I bought high end Good Year Ultra Grip Ice WRT's for about $500 all said and done.
I had purchase TPMS for my CR-V and spent about $100 on ebay. Needless to say I was very upset when I found out the cost of the TPMS from the dealer being over $90 a wheel. I then was even more upset when i found out there are no aftermarket sensors for the car to date.
After a little research I discovered (and confirmed with dealer) the part number for the TPMS if 40700-3VU0A it is often listed without the dash 407003VU0A. I tried finding these sensors on eBay just listing my year and model but could not find anything at all. Searching with that part with no dash pulled up some hits however the prices were still high.
After a couple weeks of checking daily i found some used sensors for only $60 on eBay. I wasnt too worried about them being used as they seem to be only used on the newer Generation of Rogue so they are most likely less than a year old. I have not installed them yet so I cannot confirm they work, but I did my research and confirmed with the dealer they are the correct part.
Here is the link from ebay.
