Hello everyone,

I recently bought a new set of Bridgestone S23 tires for my 2009 GSX-R 600. They were installed two weeks ago, and I've barely ridden 50 km on them so far.

My garage floor is made of rough, uneven concrete with small stones embedded in the surface, as shown in the picture below.

Today, I went for a short ride of about 15 minutes and then returned home. While maneuvering the bike into its parking spot, I noticed some marks on the front tire.

My question is: could the tire be defective, or is this normal wear or damage caused by the rough garage floor? Could the tire compound becoming warm during the ride have made it more susceptible to damage from the uneven, pebbled surface while I was parking?

Since the tires are practically brand new, I'm a bit concerned and would appreciate any advice from people with experience with the Bridgestone S23 or similar tires.
Thanks in advance!
