Based upon my Google search, those were the OEM size on the OEM 18x9.5" wheels...assuming you have the factory wheels, they should fit. I recommend you look at the wear on the tires you've linked against the tread picture of a new tire...both pair have been used long/hard enough to slick some of the tread blocks. Also, you might want to get the manufacture dates off the tires from the seller to determine how old they are...for my money, older than five years is a non-starter (not a big fan/user of used tires...had a bad experience). Good luck.
