I've been able to find the stock tires for as low as $160ish. With that being said what type of tire do u expect to get for less then that price? Probably gonna be a cheap tire if so.
That's why I'm thinking about putting on OEM replacements. Costco finally carries our tires, and it's hard to be the price when they put it on sale...especially with their road hazard warranty & lifetime (for the life of the tires...lol) balancing, etc.
Don't know if I can find a better tire for the price. It's designed to do one thing very well...get the vehicle around a track as quickly as possible. Yes, you can put on harder compound, and/or all season tires, but you trade off "stickiness" for either longer life or better traction in the elements. Both of those tire choices mean your lap times & basic handling will decrease. But if you don't want, or don't need your X-Runner to handle like it's on rails, by all means select harder compound replacements.
