Tires shouldn't dictate how you ride. I never push a cycle to its limits on the street anyway.
Tires shouldn't dictate how you ride, just like the sound of one's slip-on exhaust shouldn't, but they do. It's just human nature for most people. If one wasn't going to drive a sporty vehicle somewhat aggressively, it isn't really that savvy a purchase to begin with (as in there are more convenient options).
"If you need to make a quick direction change or stop quickly, a crappy OEM tire isn't going to respond like a fresh quality tire" - If that's the case for someone, 9 times out of ten they already made the mistake before the accident was inevitable. Just speak with any motorcycle instructor and watch him chuckle at how many people say that tires were the cause of their accident. Or look at accidents statistics where booze, lack of licensing (read competence), speed, inattention and user error are at fault for most accidents. Again, I'm not saying better tires won't help, but they are relatively low on the list of safety priorities when starting with an OEM tire in normal condition.
"The cost of tires is irrelevant to me. The consequences of using a questionable set of tires past their prime is too high, and ultimately way more expensive, compared to replacing them with a quality set." - Talking about the cost of a potential is hard to do objectively. I imagine it's safe to say that at least 90% of people who don't care enough about their vehicle to join a forum to talk about it ride OEM tires until they're more or less spent without issues or tire-related accidents. So to take an accident for granted if I don't upgrade my tires right away gives me a bit of cognitive dissonance. For regular street riding, if the need to upgrade right away is so great, the only message I take away is that they're not riding enough miles to begin with. After all, it's not like tires last that long anyway. 3-7k miles and it's already going to be a bit squared and worn enough to justify upgrading.
Anyway, I've long since realized that using OEM tires is potentially the most controversial topic on this forum, even more than oil. I find it a bit amusing. I don't disagree on the benefits though, just the urgency or inevitability of an accident for normal riders.
