Oh wow thanks guys, with all your experience and advice I've got a pretty good idea now what it could work for me in the future.

So far the self sealing tubes I've got for my bike has gone well, I did notice a bit of a difference when you are riding the bike, it seems a little heavier but nothing of major concern in my part. As long as I don't have a flat and stay in the middle of no where trying to fix a tube I'm ok. I just want to get home and then I can fix anything that is need it to keep my bike in good condition to ride the next day.

I did went to a bike shop and they recommend me the Mr. Tuffy Ultra Light Liner but I had no idea until I read this thread and then make my research about them, the guy at the store said it would help allot but I don't want my bike to be heavy to ride...and that is what buzzbee is saying...and I quote:

"I had trouble in the past with tire liners; they wore holes in the tube over time where the overlap step is.
Right now, I take the overkill approach and it works well, but is heavy and slower.
Thick thorn resistant tubes with Slime inside (schrader valves),
Kevlar belted Schwalbe tires
65PSI in a 1.9"x26" tire

I'm trying to avoid flats, I do not like fixing them in the dark, or in some neighborhoods."

So I don't know I might get them, the ultra Light the guy at the store said they will install them for free, so I'm planning to get a new front tire and then install those things...don't know yet but I'll keep you post it.

Thank you!!!!
