New Tires in Motorcycles in Thailand Posted 1 hour ago 5 hours ago, eisfeld said: A picture can't tell us how hard the rubber got and if it will explode, deflate etc at any point in time. The good thing that I can see is that there are no cracks yet. The best way to see if they are still useably is first to touch and see how the rubber feels, then go for a slow and easy ride and after warming them up a bit, see how they handle. Since your bike probably doesn't have ABS (or does it?), lock up the rear and check two things: 1. How easy is it to make the rear lock up? The easier, the less grip the thing has. 2. Does it produce a lot of strong smell when skidding on the asphalt? In my experience an old brittle rubber will produce a lot more nasty "burn" smell than a fresher rubber. When I bought my CBR back in 2017 from my neighbor's wife, I actually bought two of them, same year 2013, a white CBR-150R an a red one. I kept the white one with 4 kilometers on the odometer and gave the red one with 8 kilometers on it to my wife's son. He and his wife rode down from Chonburi for visit arriving last night. I went out to compare his tires, same model, to those on mine since he has already racked up over 16,000 km on his bike. His tires are pretty worn as you would expect, but the tread still hasn't worn down to the wear indicators although it appears that his bike's tires have lost a little of their roundness. Rubbing the tires with my fingers, his tires feel fairly smooth as compared to mine which feel more textured. Even those his bike has been parked outside for the most part, I still didn't see any cracks along the tread or the sidewalls and near the rim. The OEM IRC Road Winner RX-01 tires may not be the best tires for grip, but they sure are durable. It's my understanding that they are manufactured with a fairly hard compound for long life and after 6 years, the rubber is probably even harder, maybe bulletproof (lol). A couple of days ago I was out riding and I was following a pickup truck pulling an empty trailer driving slowly up a hill. Right when I pulled out to pass, he began a right turn, no signal (TIT). I immediately hit the brakes and the wheels locked up, mostly the back brake. Luckily, the truck driver saw me in his mirror and stopped at the halfway point in the turn before the trailer began it's turn and I stopped about a meter and a half from the side of his pickup. I looked back and saw a broken black mark on the pavement as if the tire/tires had skipped along the road; the road was kind of rough and bumpy. This is the second time I've had to lock up the brakes on my bike, both times it appeared that it was the back brake that mostly locked up; my CBR doesn't have ABS. In both events, the tires didn't produce any type of smell at all that I could tell and after inspection, there was also no wear spots. Of course, in both incidents, I was not travelling at high speed, but fast enough I guess. I guess, at this point, it all boils down to whether I have confidence in these tires or not. I guess that a certain lack of confidence in these tires due to their age and due to the many reviews I've read about these OEM tires not being very grippy has made me very reluctant to lean the bike at higher speeds in turns. Maybe this alone may be reason enough to replace the tires. If I can get new tires for Baht 3500 that would instill more confidence in my tackling curves and such, it might just be worth it even if my old tires still have a lot of tread left on them, just saying. This is what I will have to decide for myself. Thanks for everyone's suggestions; I'll post again if I change out my tires and let you know what I think of the new ones.
