To prevent flats on a Bike: slime or tire liners?

I hate getting flats, especially on my commuter bike, when I'm not on leisure time. Even with beefy tires (mountain bike with street slicks), I will run over a screw or nail.





I've heard of Slime tire sealant, and Mr. Tuffy tire liners. Do you use either/or/both? How well do they work?|||The simplest solution would be to get puncture resistant tires. I also got a lot of punctures because I ride in a city environment (plenty of broken glass), until I got a pair of Kevlar-layered Armadillo tires made by Specialized. I also religiously check my tire pressure to prevent pinch flats.





I haven't had a flat in the past 2 years. Best investment I've ever made.|||My Tuffy tire liners are good.It is always a good idea to have tire liners around the wheel of your tire to help prevent flats|||I prefer the tire liners. I tried slime tubes once and the tire didn't even get up to pressure and the tube blew out before I even got on the road.|||Use the tire liners. Most of the mechanics I know hate it if they are changing a tube to find out you used slime in it. Slime is not for cycling. I know they make it for cycling but it still sux. The best is to get a CO2 inflator and cartridges, Pedros tire lever, and PLENTY of tubes. You might want to look into getting better tires as well so you don't have to go through all the tubes. As stated above, the Specialized Armadillos are a very good for city riding. A little on the heavy side but very, very durable. Continental makes good city tires too.|||Slime works reasonable well however it adds wieght to your bike.|||Slime tires are only good for thorn sized punctures,a pinch flat....forgewte about it.I perfer not to go tube less so i use tire liners and never over inflate my tires|||Continental makes puncture resistant tires. Snakeskins or something like that. One flat in three years of city riding vs one flat enery 100 miles in years past.|||They do sell solid tires, which have a hard foam rubber core equivalent to a 100 psi tire, slightly wider than normal road bike tires. The only thing is you need the tubless rims, cause they are glued in place.
