Keep on getting flats, don’t understand why. I am 6’5" 220 haha. Got two this morning. Is there any tire tube combo that is bombproof?
Cheers Rick
If they’re pinch flats, pump the tire pressure higher. If they’re nails, or road debris, ride cleaner roads. If it happens in one specific spot, check the rim tape or look for the foreign body imbedded in the tire. You have to know how you’re flatting before you can fix the problem.
Prob pinch flats and need more tire pressure thanks

Are you checking the inside of the tire casing after locating the flat to make sure there’s not still something stuck in there? Likewise with the rim/rimstrip? Not impossible to get 2 unrelated flats in one morning, but usually 2 that close together are more likely the same underlying problem not getting fixed.
x2 on pinch flats…unless it is caused by an actual puncture check your tire pressure. What type of times and tires are you running? What pressure have you been riding on? Probably should be at 120 - 130 psi depending on your tire.
Running Conti clinchers prob 100psi. Got flat on front and not 5-7 miles flat on back. I’m thinking pressure not suffice.

Yo HMIC,
I whined about the same thing in a thread last year.
I’m 6’3" and 220lbs.
We get no sympathy from the pencil necks. heh.
Couple tips I have had offered are good, I pass them on now.
-
Taller tires: 25c possibly, 23c minimum, well-inflated as has been suggested above.
-
Use an extra rim tape, or cut an old tube about 3/4" wide and place it between the tube and the tire. Yeah, it makes the tires a bit heavier, but we aren’t Criterium riders and it’s free.

I commute 50k round trip daily and during the darker months I use heavy duty 27" wheels & tires w/Schrader valves. So I ride a little slower on them, changing a flat in the dark, cold and wet sucks.

That will do it. I think anyone over 200lbs puts a larger than average load on the wheelset vs. the 150lb guy.
I (weigh between 200-210lbs) use Conti’s, but run them around 120 - 125 psi. I think even Zipp recommends around 120-125 psi for their clinchers for individuals over 200lbs. Give it a try and see is this helps.
Also, when you install your tube make sure that it is seated in the tire properly so that it doesn’t “get” pinched once the clincher is on the rim and you start inflating…double check to make sure the beads on the clinchers are seated well.
I was having similar issues, bought a decent floor pump and and pump up to 125. Haven’t flatted since.
Best of luck…
at your weight, 120psi will be safer from pinch flats and faster too
Running Conti clinchers prob 100psi. Got flat on front and not 5-7 miles flat on back. I’m thinking pressure not suffice.

Pinch flats are also called snake bites because there are 2 small punctures that look like a snake bit your tire. The fix for that is sufficient tire pressure, wider tires, and avoid potholes, pavement cracks, and similar hazards where the wheel contacts a hard edge.
If you find lone punctures that seem to occur in the same area of the tire, there might be something stuck in the tire - usually a small piece of glass or wire. Examine the inside of the tire by sight and touch. If you don’t find anything then look closely at the outside for anything that looks like a cut or puncture. If the problem continues and you can’t find a cause, replace the tire.
One other thing is to evaluate your route for possible hazards. I was experiencing several flats a week once and narrowed the cause down to an empty lot that apparently produced enough thorns to cover a block or more. I started detouring around it and my flatting problem stopped.
Jackmott was kind enough to walk me through my similar problem with snakebites a few months ago. The solution was to make sure tire pressure was truly above 120psi, and I dropped five pounds of body weight too. Haven’t been snake bitten in the few thousand miles since then.
I ride at 170lbs, and had a lot of flats this year. Mostly I would get after-ride flats where one of my wheels would go flat after a ride. Look at your tube. Where is it going flat? Road side? Rim side??? My flats were all happening on the rim side. Turned out, Mavic did a sloppy job of putting my rim tape on, and they also left all the spoke holes sharp with metal sticking up. New rim tape and filing down the spoke holes 100% fixed my issues. Good luck!
