Within two weeks of buying my crossfire I noticed a screw on my back right tire, I ended up having to take it to two different tire repair shops to patch it because the first place I went to did not have the right equipment to get the 19 inch tire off. When I went in the tech tried several times unsuccessfully to patch it, but the patch would not take, so he ended up leaving the patch in place and then plugging it. The total cost was $2.00. I was nervous about it for a while, but have had no problems since last May -
