Then when you eventually get them on pump up to about a bar, rock the tire back and forth every few inches all the way around the rim, let the air out and do this again a few times. Then pump to 5/6 bar let out all the air and do it again rocking the tire. Bit of a ball ache but when the finally sit right they roll like tubs once you inflate them up to plus 8/9 bar. Also to get them to last and keep their springiness let out almost all the air out after each ride. And lastly if you use latex you pretty much have the best combo ever
