Q:why do some tractor trailers have a loose tire (not mounted on a wheel) on the back of the cab or under the trailer? wouldnt it be better if it were on a wheel?

Tires on Trucks are not mounted like on cars.they are hollow and the lugs hold the mounted tire to the axel not the rim.

Q:On a rear wheel drive vehicle, which tires take the most wear, the front tires or the back tires, and why?

It depends on how you drive. If you brake hard your front tires will wear down faster since they provide the most stopping force. They also have the most weight over them. And as you corner the edges wear down. The rears however wear out quick if you drive like an idiot. It's best to rotate your tires front to back every other oil change to keep the wear fairly even. A point about braking, remember your tires are the only thing stopping you, your brakes only slow down the rotational momentum. Brake early and less hard, you'll save money on tires and brakes as well.

Q:how many years can tires be driven without risk?

check dot number on side wall last four numbers tell when it was made how to read dot numbers how to read tire wear how to read tire tread 5 yrs maybe but knowing how to check and what to look for like tire wear and tread depth heat cracks mean more to you than how old they are where i live they good for about two yrs cause its hot most days and the tire dry out and side walls crack bad

Q:Nitrogen in car tires, yes or no.

To be quite honest, I have nitrogen in my tires. Never again. I bought new tires, had nitrogen put in them. For some odd reason, they tend to leak just a little.

Q:WInter Tires: do we pay extra to change back to all-season tires after winter?Do we need to buy 4 tires or only 2 for front wheel drive cars?

If you buy a set of steel rims to mount the winter tires onto, they won't charge to just put your original all-season tires that are mounted on your stock wheels back on. If you have them mount the winter tires on your stock wheels, then yes . they will charge to remount and balance your all-season tires back onto your stock wheels. You want to buy 4 winter tires - the handling characteristics will be quite different if you only buy 2 tires for the front. This can throw off the balance of front rear - which can be very dangerous.

Q:I need your opinion on goodyear weatherhanders tires and goodyear intergity tires. please give as much detail with experience as possible. thanks

Below are peoples reviews on the integrity tires, could not find info on the weather handlers. If you look at the ranking of the intergritys they rank 18th out of 21 tires surveyed, follow the links and see all 18 tires which scored better in this survey. Interestingly the Goodyear Assurance tires came in first in the survey.

Q:Why is it that there are always more tire blowouts during the warmer months. Seems everywhere I go there are tire pieces on the side of the road.

hotter temps mean hotter tyres means weaker tyres means more pressure in the tyres means more blowouts or maybe you just get out more in summer?

Q:i was wondering cause i wanted to get new tires and my tire size is 265/75/15 that is what it is right now and i was wanting to know if could i fit 4 new tires 235/75/15 on that rim would that make any problems?

there should not be a problem because your going to a smaller diameter tire you will get more turning ratio but that you might have to recalibrate the speedometer

Q:A friend told me to say that the road to repair the car tires, learn time is short, a month to learn, and then come out their own engage in what I have done 26, no long-term plan is not a way, I would like to ask you Do not repair tires?

To the car now more and more, and many cars will be due to different circumstances caused by tire wear. In the 4s shop is generally changed, so repair the tire is also good, really do not need a long time, it will be.

Q:Now we all know that a large tire covers more distance than a smaller tire per revolution. I was curious about how an odometer works with respect to tires - would you actually cover more distance with larger tires, thus cheating the odometer? Or is this calculation just negligible?

bigger or smaller tires affect the number of revolutions of the device thats operates the speedometer. that same device, will also handle the Odoneter The proper factory recomended tires for that car, will give the best and most accurate preformance of your speedometer/ odometer
