My back tires have no tread while the front ones do, i was wondering if anyone could tell me the size of the stock 2006 back tires. thanks

 

did you look on the sidewall?

 

Here, this should help you a little bit also. https://www.s2ki.com/forums/index.php?showtopic=326003

 

Lol looking on the side of the tires does help to know. But the answer is 245 is stock. But 255 is popular. But u can also fit 235 which I highly don't reccomend it and u could also fit 265 on there too. And all these tires have a 40% side wall. P

 

The complete size is 245/40R17 and you can use a 255/40R17.
If I can help with the tires let me know.
