If I install 4 winter tires without the tire sensors valves is the dash monitor will remind me constantly that my tires are not inflated properly or only a dash monitor light will stay on. The monitors are selling for 40$ each and it adds to the price of the tires which are already quite expensive on the 17 inches.

 

Yes, they can be $160 for the set of TPMS's, but the bright dash error lamp won't be lit all the time and they can alert you to a tire pressure problem before it turns into an emergency or towing expense, which could be greater than the $160. Our TPMS's have saved us twice from such emergencies. As long as it works, I think it's well worth the expense.
