Update:  The Rattleback tire failed after about 2500 miles.  The mechanism of failure was quite disappointing.  About .75 miles from work the sidewall blew out (And no, it was not from the brake rubbing, I checked).  I had to hoof it the rest of the way in a downpoor.  It was good to find out at I can run that far with relative ease.  But it meant that I had to catch a ride home with a friend in his undesirable vehicle — not something I like at all.

Sidewall Failure

After the Rattleback tire failed, I contacted Sweetskinz and showed them the blowout.  The representative said that that tire wasn’t really designed for how I was using it and said he would send me a couple of more tires.  He sent me the Eclipse.  After about 6 years on the front and well over 5000 miles, my Hutchinson Python had had it.  So I through the Eclipse on the front.  It looks cool but that’s about it.  In tight corners, it feels like you have the brake on due to the tread pattern.  The tire also feels squishy and rolls to the side easily even after I replaced the rim with a wider one.  The compound is also weak, at best.  I burned through the red compound relatively quickly and found the ugly cream colored compound beneath.  After about 2000 miles on the front the tire is virtually trashed.  I would not recommend these tires unless your a very casual rider and only put in about 1500 miles every few years.  Sorry, Sweetskinz.  Good concept, poor durability and performance.

I came across the Sweetskinz website while searching for different styles of tires for bike commuting and bike commuting at night. I thought the tires looked pretty cool and thought they would be especially eye-catching at night. About two years later after wearing out one knobby while bike commuting, I thought about Sweetskinz again and was determined to give them a try. I bought the Rattleback Semi-slick as I thought it was the least dorky of the patterns offered. When I received the tire I was surprised at the weight – these things are a big chunk of rubber. Of course, I also tested the reflectivity of the tire which appeared to be pretty good. I have been riding the tire for over 4 months now (about 1500 miles). I do like the tread pattern and I have only had 2 flats over this time. This is pretty good for a back tire in Memphis given the abundance of road cacti here. I have not had anyone comment on the night visibility of the tire which I had expected. The reflective material is only a thin covering so it immediately wears off of the tread and thus is not visible from behind. Being visible to undesirable vehicles traveling perpendicular to me doesn’t really seem all that necessary. I would much rather be visible to vehicles approaching from the front or rear. I don’t think the Sweetskinz really help with that. The most reflective portion of the tire, the sidewalls, quickly become coated with brake dust and other road filth, especially in the wet winter months when you need visibility the most. You can wash them with soap and water but I’m too lazy and it’s too cold for me to do this.
