Question: is this tire foldable?
Document: It was difficult to get this on my rims (very tight, I had to spray the tire with Windex), but it has great traction for winter riding.
I live in Charleston SC and we have a lot of uneven streets and cobblestone downtown. This tire handles the uneven areas very well and has great grip.
Bought these tires because i needed a little more traction in the rain. After 3 months the sidewalls on them have started to crack around the complete tire. What a waste of money. I maybe got 100 miles out of them
I am a weekend rider with about 150 miles on my front tire. The tire formed a bubble on the side wall with 80 PSI. I took the tire off and could feel the weak area in the tire from inside. Not under warranty after 1 month.
The tire itself seems fine - now that it's finally mounted. We destroyed one tube and the bike shop destroyed two more before finally getting it on. Wow, what an ordeal. The tire is the correct size for the rim according to all the specs, but the bead is so stiff it made it very difficult to mount.
After tremendous effort, I got one tire on. Then, realizing that, if I had a flat in the middle of nowhere, I would have to remove them, I tried to get it off. Couldn't do it, broke tire irons, and, believe it or not, had to cut it off. Ridiculous! Bought some tires from Performance and got them on and off easily.
I ride my bike in city and somewhat not pave road as well. The city I live in is considered bike-friendly, but still lots of roads are not flat perfectly paved. Bumps are everywhere, sometimes you can find broken grasses too. With this tire, I have no worry about getting flat by them.
It is extremely difficult to mount on the wheel. I mounted 4 of this tire, and I broke three tire levers. If you don't wanna struggle, you may wanna go to local bike shop. The point is tho, you need to bend the last piece to the opposite side of the rim. Strong tire lever can help too.
Once the tires were finally mounted, I took the bike out for a test drive. First impressions were that I felt like I was riding in sand and that these tires were really heavy - I'm sure this is good for puncture protection, but the drop in performance was a deal breaker for me. I'll be switching back to a proper road bike tire ASAP.
In 25 years of riding and changing tires by hand I must say that this is the toughest tire yet. It simply is too tight to mount by hand. I am afraid to use it as I would never be able to change a flat on a ride. I like the look, quality, thickness, etc but will return them due to these mounting difficulties.
Answer: yes
