I have my advice on tires, and it's this, Do Not Go Cheap On Tires. Because tires are what keeps your bike on the road and a good set is worth ever penny. You can say that you owe your safety while riding to your tires. So if you want to go cheap, it's your bike and your safety. Personally I think going cheap on tires is the worst decision anyone can make, and if you wife thinks cheap tires on your bike is the way to go, well then she does not think much for your safety. That's all I have to say on that. Good luck.
