    Default 235 60 r18 on gxp

    I found a set of tires pretty cheap in 235 60 r18 and I need a new set for snow. The oem tire size is 255 45 r18 on the front and 225 50 r18 on the back. Will they fit?

    that's what we were thinking, they are a set of blizzaks I could probably get for 250 installed.

    235/60 are 29.1" tall. Stock is only 26.7. That's almost a 2 1/2" difference in overall height. Those are small SUV tires.

    If you know how to do the math you don't need that

    it wasn't hard to figure out that the 235/60/18 were 2 inches taller, I just wasn't sure if they were too tall or not.
