tire liners

tire liners

Had a flat about 60 miles in on Saturday's ride.  Tire went flat quickly as it was a nail about 3/4 inches long.  Easy change & since I was close to New Frredom I stopped at the bike shop for another tube & some CO2 just in case it happened again in the last 15 miles.

I am interested in Mr. Tuffy tire liners.  This is primarily because of some Continental Ultra Race tires that were really cheap that I would like to begin using.  However, they are famous for flats since the rubber is so soft.

Anyone used Mr Tuffy's or any other tire liner with a road bike? 

Thanks!

Re: tire liners

Jim,
I used Mr. Tuffy's for a short while. They are not worth using IMO.
They definitely protect the tube from puncture, but there are many downsides.
1. they are rather difficult to instal in the tire.
2. They will make the tire stiffer and heavier thus increasing the rolling resistance significantly.
3. they can cause flats from rubbing the tube where the two ends of the tuffy liner meet. 
You'd be much better off finding a quick(er) rolling touring tire like pasela tourguards or similar.

Re: tire liners

Thanks for the feedback Bob!  Installation does sound a bit challenging as Mr T suggests using a local bike shop, but I can live with that challenge.  Stiffer & heavier is a concern. The stiffness will be a ride it & see test, but as I am small my bikes are all pretty stiff already.  There is a set now that seems to be a bit lighter so hopefully weight won't be a big deal.  Ralated to the flats caused by the ends there is quite a bit about this on one of the forums, it ssems that the ends need to be smoothed.  Some have suggested sanding, some suggested heating and hand flattening and others seem to think this is an issue that has now been addressed by Mr T.  I think I will go ahead and give them a shot for $10 ~ $15 as it seems to be relatively low risk.  If they turn out to be crappy they will be retired with the Conti's which were a bad puchase in hindsight.  Thanks again!

Re: tire liners

I have used Mr Tuffys for a number of years and find them generally worthwile.  Remember--they only protect your from things hitted the mid tred--occasionally you will still get a flat from the edge of the trend especially if you ride on rougher trails (like the NCT).  The new ones are thinner and lighter than the old ones.  I have not had problems with them pinching tubes.
