All this talk about old dry tires in the thread with the video of the scooter crash has got me worried about a few cracks I see on my front tire. I bought my '03 Scarabeo 150 last summer which had only 1253 miles, and what I assume are the original tires (Maxxis) which have plenty of tread and seem to be in good shape... Except for some shallow cracks along the bead, as shown in the photo. Do you think its risky to continue riding on these tires? The rubber does not seem hard and otherwise in bad shape, However I do run this scoot hard and up to 75 mph sometimes.
