Just wondering how everyone is liking the no flat tires such as the ones on my 05 Lazer. They never go flat but they ride a bit rougher. Which do you like best and why? Has anyone converted back to the air filled tires or the other way around. I will have to say I have pulled some big nails out of them that would have cost me some down time. But I used slime in the air filled tires with good results.
