Hello All:
Recently purchased the above vehicle. Time to buy winter tires (and even if I don't buy new tires, the ones on it now will need replacement in the Spring at about 35K miles).

Currently has 245/45-17 on all four wheels; however, the owners' manual seems to indicate there should be 235/45-17 on all four OR 235/45-17 on front and 255/45-17 on rear. My concerns are:
1. I don't know what size to buy: the size I now have (Continentals, appear to be original) or the size the owners manual recommends.
2. What is the reason for different sizes on front and rear? How do I know which I should have?
3. Will the current wheels accommodate 235, 245, 255/45-17 tires or do I need to change wheels (I think the ones I now have are original--five spoke chrome).
4. If I need different/new wheels, where is a good place to find those that will work best (including dealer, if that is the best thing to do.)

Thanks in advance.

 

Well its pretty simple, just follow what the manual stated, get the recommended size. About your inquiry with the size difference of the front and back, reason for this is because of traction. Your vehicle is a RWD meaning to say it propel from the rear tires. For the brand I suggest getting Nitto tires Motivo, its an all weather tire or SN2 specifically designed for winter applications. Where to get it? You can purchase with your local tire shop or even online.
