Motorcycle tire review and tips especially for Yamaha FZR 250 R 1989 tires
- Air It Out: Check tire pressure every chance you get. There's probably no simpler procedure that's more important and more ignored by bikers of every stripe. The air, not the carcass, supports the bike, and underinflation is a tire's number one enemy. (Make sure the tires are cool when you take the reading.) Contrary to most belief of riders that lesser pressure tire offer more grip on wet roads---For a better tractrion in wet conditions, increase pressures by about 10 percent. Unsure of what the pressure is supposed to be? Look for a sticker somewhre on the bike. It is also probably on the VIN (serial number) plate hear the steering head with the gross vehicle weight rating (GVWR) and gross axle weight ratings (GAWR) information. The simplest and most important thing you can do for your tires' health and your safety is keep them, inflated to the designated pressure.
- Stay Smooth: This is common sense--avoid potholes and sharp objects on the road that can compromise your tire's integrity. The same goes for curbs.
- When inspecting your tires check the tread wear indicators (TWI), which are noted by the TWI (some tires may display logos etc in place of TWI) marking located on the tire sidewall. Look towards the center of the tire to locate the actual tire wear bar which will be located in the tread groove itself, as a raised bar. When the tire is worn to this indicator it is time for a new tire. We have actual samples of worn tires to show you the amount of skin left between you and the road so to say. It is scary. The remaining amount of rubber is actually less than is apparent from the outside.
- Hydroplaning is the effect when the tire rides up onto the water surface of the road. What effects this is both the remaining thread depth, speed of the motorcycle and the amount of water on the road surface. In wet weather slow down and before going on a long ride for safety sake replace your tires if they are near the wear bars...its your skin.
- Tubes should always be replaced as these will wear just like the tire itself. When installing tubes be sure to locate the valve stem retaining nut all the way to the top of the valve stem so that it touches the cap. This way if the tube spins inside the tire you can see this by the tilt of the stem before the stem is torn from the tube itself. On tubeless tires always inspect the valve stem for cracks and dried out rubber, since these can crack over time and leak air. This thinking applies to car valve stems as well.
