I've corresponded with a few different riders about the details of my car tire conversion. It's not for everyone, but it can be done safely and it rides just fine if you're willing to accept a few minor compromises. For me, those compromises weren't any worse than, and in many ways were better than some of the rock-hard "high mileage" bike tires out there.
It starts out feeling like a tire that's been worn flat from too many highway miles. And it takes a bit more countersteer to get it to set and hold a line.
But you get used to that fairly quickly, and then the tire wears more on the edges than the flat, so it gets "rounder" over time. Note that "over time" can be anywhere from 20,000-40,000 miles . . .
I can ride the bike just as aggressively, and with just as much confidence as with the factory bike tire. In fact, I'd even say better than some of the harder-compund bike tires that tend to twitch on tar snakes and can really
suck in the wet. I can still drag the pegs at will and with confidence (sparks or no sparks
). And as a few riders here can attest, it doesn't seem to slow me down much at all . . .
Like I said, it's definitely not for everyone. I would never tell anyone what to ride on their
bike, but if they ask, I'll give an honest answer as to what works on my
Remember that I'm running 11-day Endurance Rallies, where every minute spent messing around is time that I don't get to sleep. So losing an hour or more fiddling with tires is a huge hassle for me, and could easily cost me a win.
So, for me, the minor hassles are worth it, and honestly, I've seen no real downside to it.
