If you used traditional sew-up glue you should wait at least 12 hours before doing any serious cornering. If you need to race right away you can use Fast Tack and corner confidently within an hour. Be sure to spread the glue evenly over the surface of the rim using your finger or a brush. To get the last section of tire onto the rim without making a mess grab the remaining 3 or 4 inches and lift the tire away from and over the rim. This can be difficult if you forget to stretch it beforehand.
Some glues work better than others in hot weather.
Fast Tack works best followed by Wolber and Vittoria with Clement in the middle and Tubasti at the bottom of the list. When buying Fast Tack be sure you get the real thing. 3-M sells other trim adhesives in boxes nearly identical to Fast Tack. Be careful that whatever glue you do use has not separated in its tube. If it has, take a spoke and stir it up before you squeeze it out.
