Motorcycle tyres as a present

Carline had been thinking for a long time, but she had not come up with any great ideas. What could she get Robert for his birthday? She knew that he preferred practical gifts, something that he would use for a long time, preferably something connected with his interests. He was not interested in useless gadgets or funny gifts from cheap souvenirs shops. One of his biggest hobbies was riding his motorcycle, and Caroline would probably have to think of something connected with that. She knew very little about motorcycles, so she decided to call Frank, Robert^s brother, to help her. He advised her to get a set of brand new motorcycle tyres for Robert. He had been riding on his old tyres for definitely too long. The treads were already worn out and the vehicle skidded very often when the roads were slippery. But how could Caroline choose the tyres by herself? Well, she asked Frank to help her straight away. He sent her some links and explained which motorcycle tyres would be best. She finally chose a reasonably priced set of quality tyres (she read opinions left by professionals, so she was sure she was not buying poor quality stuff) and she ordered the set online. She just hoped Robert would be happy with the present.
