And what factors depend on tire replacement?
no no no no no because guniea pigs are that fat kids out or the rodent fam. they just like to run around in their cage oh but if you wanna get a toy for your guniea pig just get a cat toy with alittle bell in it and they could play with that hope i helped!! *:)
No it is a waist of money if you do because I have two guinna pigs and they don't spin on wheels
Every tire manufactured today has tread wear indicators at multiple positions around the tire, eliminates the need to use Lincoln's head to measure tread depth, the tread wear indicator runs 90 degrees to the direction of tire rotation and extends the width of the tire. If you see a line across the tire or even part way across the tire, time to go tire shopping.
In certain types of riding, a squared tire is a fact of life. If you replaced the tire at the first sign of it, you would be throwing away money way more often than you have to. It really does change the handling characteristics of the bike though. Depending on your riding style, you may notice it, and you may not. It's not exactly dangerous in the way that you are risking your life every time you throw a leg over and ride. It's just dangerous in that anything that degrades the handling of your bike is less safe than if it was perfect. I would just change it when it comes close to the wear indicators. The best way to judge how it changed the handling is to pay close attention to your last ride before you change and the first ride after you get new ones (or at least after the new ones have been scrubbed in). I thought my Cyclone was a nice handling bike with the old slightly squared tires. It actually was a good handling bike I guess. When I had a brand new set of Road Attacks put on, it was like I got a new bike. The new rubber was more pliable and absorbed minor imperfections way better than the old set. The bike felt more stable on the highway, and MUCH more lively in the corners. It didn't follow rain grooves and cracks like the old tires did, and in the wet weather, the bike was much more confidence inspiring. Just ride it the way it is for now, but if it ever doesn't feel right don't mess around. Just get new tires and count it as money well spent. If you don't put a lot of miles on your bike, remember old rubber is often more dangerous than slightly worn rubber and the way old tires let you down can be catastrophic and deadly. (Lots of good advice here today.)
As often as they need to be. How often is that? When the tires are worn to 4/32 remaining tread depth, measured at the part of the tire with the least tread remaining (they don't always wear evenly). 4/32 in the middle but cords showing on the edges is not considered OK! Why 4/32? Becuase below that point a tires traction in slippery conditions starts to fall off like a rock. 2/32 inch remaining tread is considered bald on most tire warranties and in most states. Of course, if you do not like the traction you are getting you should always replace the tires, no matter how much tread they have. The other factor would be age. There is no concensus yet on how old is too old for a passenger tire. 10 years is however becoming an increasingly common recommendation for tire maximum age with several tire and vehicle manufacturers now recommending that any passenger tire over 10 years old be replaced. The week and year of a tires manufacture is molded into the sidewall near the bead on one side of the tire.
