Do i need to adjust tire pressure for a passenger. The model i chose isn't my actual bike. My bike a 1999 800c suzuki intruder wasn't an option in the drop-down list of models.

What are the tires pressure for KYMCO Agility 125 2017? · 25 PSI (~1.72 BAR) · 32 PSI (~2.21 BAR).
Front Tire Pressure: 25 PSI
Front Tire Dimensions: 120/70-12
Rear Tire Pressure: 32 PSI
Rear Tire Dimensions: 130/70-12

Use a pressure gauge as a reliable measure of pressure. Once you establish what the tires actually contain, you will be more able to diagnose the electronics.

Since each sensor is independent, a default would show in each individual tire. If you establish that each tire sensor is working, then the main unit must be the problem.

This stuff was invented after I quit wrenching. I can't say whether the Code in the receiver is fixed or adjustable. If it is adjustable, then it either needs to be flashed or physically adjusted to a different pressure warning level.

If your tires are actually deflating, it can be a rim leak or a puncture.

Sounds like the steering head need adjustment. I would also check your tire pressure. I usually set them at 40 psi front and rear. It gives you better overall tire wear and a hair better gas mileage. If you ride in a straight line and bounce the front end using the front brake listen for a clunk. If you hear it and can actually feel it I would start at the adjustment of the steering head. It could also be spokes if you have spoke rims.

It appears your car may have a damaged or out of alignment tie-rod.

You will need to have your alignment checked and adjusted at a wheel and Tire center or mechanical workshop that conducts wheel alignments, this isn't a very costly job, my last alignment costs was around 56 dollars (they are performed when you buy a new set of tires USUALLY), but your experience may vary depending on if the rod is damaged and needs to be replaced.

Look at the side of the tire itself, tire pressure is right there. Open the door, look down and see the sticker, the info is right there along with the size of the tires when you need to buy them. Open the owners manual, again the information is right there.

The adapter for car tires should work on the bike tires. If you are using a compressor with a regulator and gauges then with a full tank of air adjust the regulator so the output gauge is set to the pressure you want the bike tire be be. This makes it take longer to fill the tire but reduces the changes the tire is overfilled and damaged. If you have an old fashioned bike pump and want some exercise that is different than biking then that works also. The valve stems on the bike tires have threads just like the car valve stems and the valves and caps are interchangeable.

There is no one correct answer to your question. The proper pressure depends on how much you weigh, and the surface you are riding on. Most people think they should pump their tires to iron like hardness to reduce rolling resistance. In a perfect world this would work great, but, we don't live in a perfect world and you should resist the temptation. First, a couple of comments about rims and tires...

Beleive it or not, rims are not necessarily able to handle as much pressure as tires. In fact, many high end rims are limited to pressures way below what even the least expensive tires can handle. So, you may want to look on the website of your rim maker to see if there is a limit. Tires too, will have a maximum pressure rating. Be sure not to exceed it.

Road surface makes a big difference. The smoother the surface the more pressure you can run. On a rough surface, though, more pressure will actually slow you down. How can this be, you ask?

You need to think of your tire as a spring. When you hit an obstruction, your tire, just like a spring, compresses. Then like a spring, the tire rebounds. If you have too much air in the tires, you will find your bike bouncing off every little obstruction instead of smoothly rolling over them. Insofar as your wheel meets an obstruction somewhat before bottom, dead, center, you are actually rebounding back! In other words, that bounce is actually a braking action which is slowing you down. Furthermore, too much air will also cause fatigue as ever little bump in the road is transmitted through your bike into your body.

Of course, too little air in your tire will cause you to get a pinch flat because the rim will pinch the tube against the obstruction making a pair of holes that look like a snake bite.

The perfect amount of air will cause your tire to conform to an obstruction and roll over it with minimal rebound. Obviously, it will prevent pinch flatting, as well.

So, what is the perfect pressure? Well, one thing for sure is it much less than the stated maximum on the tire or the rim. I weight about 165 lbs. On a really smooth road, I'll use around 100 lbs. On rougher roads, I ride with around 90 lbs. If you weight more, put a bit more air in. If you weigh less, try a bit less. In a few rides, you should find the pressure that seems to suit you and the roads you ride nicely.

There has been lots of discussions of tire pressure in the Road Bike Rider Newsletter. Your may want to check out the

Hope this helps you understand the ins and outs (or prehaps the ups and downs) of tire pressure.

Road bikes are faster due to their generally higher gearing and especially due to their narrower tires that pump to much higher pressures. Think of your bike like a boat. When you start a boat it gets up to speed and eventually is up on top of the water (what is called planing) and then you can actually reduce the throttle and mantain the same speed. In the same way narrow tire road bike riders can get their bikes up to speed and actually throttle back and keep the bike going at a similar tempo. The tires on a hybrid bike do not inflate to the 100-130 that many road bikes tires do. We used to have a pair of racing wheels and tires at my bike shop that we would let hybrid owners borrow. They could not believe the difference.

Should be on the frame of the bike near or on the same lable as the VIN as are the tire sizes and wheight recomodations. The tires also have their maxine and min. pressures on the tires. Generally the rear tire will have 42 PSI and the front can run 32 PSI Tuning the way the bike steers and takes bumps can be done with tire pressure except never go below 28 PSI and never go above the highest number on the tire itself. If the bike doesn't have the trires on it the came with it new the best thing is to call the tech line for the makers of the tires and ask them telling them the bike the loads its going to carry and the exate tire size and model that your talking about. The pressures in the manual and on the frame and the ones for the tires that didn't come with the bike may work OK but if there other tires get the tiremakers recomodations. Many tires run best and last longest with the high number on the tire, but sometimes ride a little harder than you like.

Hi,

Offhand, the recommended tire pressure could be read on the tire itself. In most instances, this the tire pressure actually depends of:

• rider's weight, with or without passenger;
• rider's driving habits;
• type of road where the bike is often ridden;
• weather condition and ambient temperature.

Personally, I find a bit lower tire pressure on the front and standard or a bit harder at the back.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
