Well, here is where I stand.
Two or three weeks ago, I had a flat tire. It was a bad one. I rolled on a section of road that wasn't flat at all and it ruined a tire. Put a hole in the tire about the size of a dime. Got it replaced at a LBS 3 towns over. About a week ago, I planned out a 30 mile trek from Howell in Michigan, to Hartland, then South to Brighton, and West to Chilson Road, and back up to Howell. I get 5 miles down the road and another flat, same tire. This time, it was a very small hole, that maybe a needle made.
Instead of going to any bike shop that I knew was closed, I went to Dicks sporting goods in Brighton and looked at their selection. I decided to get two Slime inner tubes, some tire levers, and a Coke. The Slime tubes are guaranteed to stop a hole 1/8 of an inch in diameter. Which seems to be a pretty good sized hole.
I get home, and proceed to change the tubes on both tires (I decided to do both because the one good tire I do have, is now a spare). Let me tell you something; anyone who said that changing a bike tire was easy is snorting WD40 and farting pixie dust. It took me an hour and a half to change ONE tire. It was ridiculous.
After almost 3 hours of huffing and puffing, I finally got them replaced. Filled them up to 100psi and took it for a test ride. IT WORKS!!! I've been riding for 4 days and haven't had a single hiccup. I checked the air pressure today; 100psi. I consider this a personal victory for me.
I need some Advil.
