Does it come with both tires

Yes I believe I paid about $99.00 for both tires.

Will they fit a kfx400 400 with ss rims 20x11r9?

I have no idea bro I had a 2006 yahama yfz450 and it fit those

Tires are exactly what is described. Packaging was not very good wrapped up with twine

Tires are exactly what they should be.Packaging with twine wrapped around 2 Tires Way too tight.Tires are now triangle shaped which will make for a difficult install.They did show up early and look like they are quality

Nice little tires

They only sent one of 2 sets I ordered but sent the second after contacting the seller. Overall they’re a little smaller than the ITP Holeshots they’re replicating and a little harder compound but they work as expected and for the price they’re a great deal.

These are very good tires

They are aggressive and tough. I was extremely impressed by the craftsmanship as well as how much meat are actually on these tires. So I'll give it a 10 out of 10 for craftsmanship. They made my quad look new again for one thing and when on the trails they give me a smooth and solid ride that claws the ground or mud with ease, so performance wise I would give it a 10 out of 10.
