Flats, flats and flats

I'm currently running hemisphere tires that came om my Specialized bike. 700x38c I get flats almost every time I ride. I'm in a small city so there are no sweepers to clean the streets. I'm looking at Schwalbe Marathon Plus tires. The reviews on THERE web page are all good. Has anyone here used these tires? I did the search and found a few results but none with my tire size. Thanks.

I had those tires. Had a flat every 260 miles on a tour from NY to LA.

Have you determined the cause of each flat? Like located the hole in the tube and matched that to the same area on the tire?

Yes, find the cause first. That's why it's a good idea to have the tire's label lined up with the valve, so you can see how far the hole is from the valve, and then check that part of the tire carefully.

Are thorns causing the flats? Sorry, I don't have those here. But there's been a lot of threads on thorns, so try searching.

Are you picking glass out of the tire? Then avoid riding along the edge of the road. Cars keep the tire tracks in the lane clean. I get less than one flat per 5,000 miles from glass, since I watch where I go. Tiny wires from worn out car tires can be hard to find when stuck in the tire.

Are the holes on the outside (tire side) or the inside (metal wheel side)?
On the inside: is there a spot where the rim tape doesn't cover the hole? Or did you hit a pothole and "pinch flat" by bottoming out the tire and cutting the tube against the rim?

Yea, i get everyting out of the tire and tube. The trash is picked up in the center of the tire. I did learn my lesson about where to ride. The tube gaurd is in good shape. I have tried all tire pressures within the specs of the tire.

Like other people said, the first thing is to make sure you're not getting a flat in the same place again and again. But let's assume you've done that.

The Schwalbe Marathon Plus tires have a reputation on this board for being the best at flat protection of any tire on this board that's available (might be others on par, but I don't know of anything that seems to get any better reviews). They're often overkill, though. If you're getting flats from rocks, it sounds like perhaps the tires than came with your bike were simply crap, and you might easily be able to use a cheaper, light, smoother, and faster rolling tire like the regular Schwalbe Marathon's as well. But the Schwalbe Marathon Plus tires are about as good as you can get.

I was riding my old Worksman cruiser, and would periodically have flats. Maybe go 6 months without any, then 5 right together or something. Anyway, I got a new bike, and it came with Vittoria Randonneur Cross tires. 2500+ miles, I think, no flats yet. Maybe I'm just lucky and jinxed myself now, but I'm sold on 'em at the moment.

Inverted treads will often pick up rocks and bits of glass. Once picked up, if the rocks are sharp they will eventually work their way through the tread and into the casing. If the casing is crap, the tire will flat soon thereafter. I didn't like my Michelin Transworld City's for that reason although I got away with just 1 flat in 1000 miles.

The Hemisphere Sports are nothing special. I wouldn't expect them to have the same protection as the Armadillo version.

I love my Vittoria Randonneurs as well, faster than they seem they should be and only 2 flats in 5000 miles. One was a goathead thorn and I made it home only to find it flat the next day. The other was an inch long staple and I had no chance.

Note that you don't need to use exactly the same width tire as you have now. You do need to match the diameter (i.e. the 700c - which is actually 622mm), but not the width. Your current tires are 38mm wide, but you can probably use anything from about 25mm up to 45mm. The exact range will depend on how much clearance you have.

I'm surprised you're getting flats from rocks unless your area has ones that are exceptionally sharp. Despite riding on lots of gravel roads and other surfaces with plenty of rocks I don't think I've ever had a flat from one (other than pinch flats when the tire was underinflated and I hit a big stone).

There are little sharp rocks all over here, but I make it a point to pick them out after every ride. My Bontrager Hardcase tires do not have a tread, however, so its the actual running over of rocks that embed the rocks in the tire. 2-3 minutes after every ride to make sure there are no time bombs waiting to happen is worth it.
