just replaced my krylion carbons. 700x23. i rode them at max pressure. i weighed between 210 and 225 during their life span. 99%+ of the miles were on roads and paved paths. some roads were bumpy with lots of asphalt repairs to pot holes. however, i didn't ride over many unrepaired pot holes. overall, i'd say the roads were avg.

i got just under 4000 miles out of the rear tire. no flats (until the tire was done for). also, had one rather deep cut in the tire within the first 200 miles.




i'll stick with krylions. luckily, i bought a backup set when i got the cut on my originals. apparently they're not being made (for the time being).
