Q:What are the differences between 91V and 91W on car tires?

W and V are the ultimate speed of the tire; that is, the speed of the tire is extremely high, the speed is that a tire running critical speed: that is, if the tire speed exceeds this speed will be prone to puncture risk. V represents 240 km / h (high performance sports car); W stands for 270 km / h (GT sports car)

Q:The tire says 35 pounds, and the door jam says 30 pounds

The sticker on the door is for the tires that were originally placed on the car. If you still have the original tires you should go by the door, if you bought new tires, you should go by what the tires say.

Q:tire psi light on in dash

This Site Might Help You. RE: how do you reset a gmc low tire pressure light? tire psi light on in dash

Q:I just refilled the air pressure in my front tires last week and they already look like they are getting flat again. There was only 8lbs of pressure when I last refilled. It seems like this happens weekly. The tires are only a year old so I really don‘t want to have to replace them. Visual inspection shows no big tears, nails or holes. My question is, is there a simple go to the store and fix it myself solution or will I have to set some money aside and take it to the shop. My back tires are fine and they are older but never seem to have the problems I‘m currently having.

Unless there is a hole or something has punctured the tire stop leaks will not work and even then the directions say to have the tire repaired. More then likely the tire bead area needs to be cleaned up and a sealant applied. I just had this done to one of my tires (20 dollars). It could be a bad tire stem or leaking valve. So there is a good chance the tires do not need to be replaced (if the tread is good), but that the fix will not be cheap either.

Q:Is there any connection with gas and tires ? It does not make sense I hear that slogan in a commercial

Yeah there is a lot. More to do with their inflation than anything else: . Here is a good example of under inflated tires costing you money. The taxi cap drives in Las Vegas were only inflating the tires on their cabs to around 15psi. As a result of the tires being under inflated it ran the meter up costing the customer more. . When under inflated the tire is a smaller diameter making it have to turn more times for the same distance a fully inflated tire will turn. Another example: Going from where I live to Dallas Texas: With my tires inflated to just 45 psi my odometer read out that I have traveled 230 miles: With my tires inflated to the full 80 psi my odometer reading will be just 216 miles. That is about 15 miles difference and about 2 gallons of gas difference. . This is what confused people on that. If figuring off the odometer and gasoline used you still come out to the same miles per gallon. However, your odometer will show that you have traveled further than you really did. I use that as an example because I know exactly how far it is from my starting point to my destination. You can verify that yourself rather easy. to simulate a fully inflated tire and an under inflated tire; Get yourself a small tire like a scooter tire. Then a bicycle tire. Now set you out a course. Mark two places several feet apart. Then roll the scooter tire from start to finish counter the number of revolution it makes Now Roll the bicycle tire from start to finish counting the number of revolutions it makes Now imagine in your head how much more gas it will take you with the scooter sized tire on you car compared to the bicycle sized tire on your car. With that little primer on tires and inflation: Yes they can if kept fully inflated: But, so will any other tire if kept fully inflated and properly maintained:

Q:I bought a car with used tires , all of the tires look good and everything. The weather did get hot and for some reason the tires keep getting bumps on them? What can be causing this problem to happen?

Those bumps are caused by air leaking between the plies of the tire. This is a very serious condition - they can blow out at any time. If you are within thirty days of purchase, take it back and demand different tires. Otherwise, you need to replace them .

Q:measurement of a tires performance

The Usual method is mount to a rim and take the car to a race track and push it to find the slipping point. This measures the dry traction. Better the tire, more grip you would have and faster you should be able to take turns. There are different rating for tires. Standard H rated tire is difficult to measure because it is ALL season tires that must perform under all different weather conditions. Q rated tires are snow tires. and Z, Y, W, V ratings are currently used for street summer only tires. R rated tires are street illegal, and should only be used in a race track. The manufacturer of the tire sets these ratings based on the tire compound used, and tread pattern. Each of these ratings have associated safe speed range. Racing tires usually have side wall reinforcement so that you safely push 150+ MPH without worrying about tire blow out problem.

Q:How do air filled tires affect the performance of a vehicle or bike, compared to a hard solid wheel alone (like on a horse and cart) or very flat or very hard tires?

If car tires were solid, the ride would be horrible, and they would cost 3 times as much. Air filled tires, absorb the bumps and grab the road in corners, so they handle better.
