The method Zorro describes is essentially the same method that I have used over the years. It also works well for me. To me, perhaps it is becuase I am all thumbs, mounting an unstreached spare quickly and neatly on the road ride is easy with a streached tire. With an unstreached tire, it can either be neat or quick, but not both. This method has worked well for me as in 30 years of rinding tubulars I have only rolled one tire, & that was entirely my fault, not the tire's. Bob
