I have always ridden a Mountain Bike and lately I've lived with a strange question related to the tire I've been using. I use a pair of 26 x 1.95 CST Rush tires that are a great cost-benefit and found easily in my country for $20 or less.
However, after a few minutes of riding on the road, it feels like the rear tire is being emptied. A few minutes after, this feeling passes and the trip remains normal, with great performance on the road and no complaints about the performance of the tire. This is normal behavior?
