300ex OEM rear tire size?

[pjcustoms]

I,ve got a 1994 300ex, wondering what was the original tire size on the rear. It has 22x11's now. I dont want to change the original ratio by putting a smaller tire on, but I like the lower profile better. Anyone have some comments regarding loss of top end with a smaller tire, or what combination works the best. I'm not racing it, but a lot of trial and some jumps.

Stock is 22x11's but you can't fine many 22's with a flat profile. I would recommend going to a 20x11. I did notice a little drop in top end speed but not much. depending on the riding you do i would recommend the kenda klaw or knarly.
