Hi-

I am new"ish" to riding on a road bike. I have been riding a road bike for over a year, but I don't get out often. Even after all this time, I find myself wishing I had wider tires. I just can not get comfortable on these tires coming from a hybrid. I am on the brakes downhill for fear of hitting a pothole or some debris. I just do not feel stable at all!

So can I get a a slightly wider tire without having to change my whole wheel? Can I put a different size tube from what I have on there currently? ANd how do I see what size width I have on there now?

Thanks for input!
