Very bad for a speed!!! decreasing 25-40%!!! Normal tires : 21km, 1:00 hour, you are fresh. This tires: 21 km, 1:23!!! hour, you are exhausted and destroyed! Wasted money. Never again! To a garbage bin!
First of all, tires are very hard to put on. But that is fixable with leaving them in hot water. the tire lever provided is metal. A plastic casing on top should be put on to prevent ruining the rim. using Zip ties are mandatory or something like Zip ties. yes the price is good, ride quality on smooth roads are okay, o gravel probably good, cornering might be tricky if this slicky stuff wont come off
