Car tires??
i bought a front wheel drive car last year and didn’t check the tires when i bought it. Well now that there is snow on the roads i found out it has summer tires on it. Not fun. Can i go buy just 2 all season tires right now and put them in the front, or do i have to buy 4 tires and change them all?????
admin answers:
I would personally get 2 new tires to put on the front. Depending on how much snow you get, you could either get the all season or the winter tires. I go for winter tires in the winter though, because we get a lot of snow. I like the wintermasters the best.
I would also rotate your tires at the same time by putting the ones on the front on the back, and when you take your new tires of come spring time, the ones that were on the back should go to the front.

What can cause car tires to ware on the inside of the wheel?
My car tires are starting to get worn down on the top part of the tire facing the car. It only does this to the back wheels.. One of my friends said it could be the lower control arm bushings (no idea what the is). Does this sound right? What else could cause this?
admin answers:
Only on the back wheels…has nothing to do with steering alignment. I suspect bushes too…I assume you have independent rear suspension and the back of the car is sagging. Go to a dealer familiar with your model, this is bound to be a fairly common fault.

car tires?
every time i turn a corner.. i squeal.. i dont take them fast or anything.. so does this mean that i need new tires? or are they low on air? it didnt happen when it was cold out.. but not that it has started to warm up.. it happens at nearly every corner.. any suggestions?
admin answers:
Tires squealing could be because of several different things.
1. You’re taking the turns too fast – which you say you’re not.
2. Your tires are getting bald and can’t seem to grip anymore – new tire
3. Your tires were already overinflated during the winter. The hot weather has caused the tires to swell up even more which is causing you to lose grip and squeal. Check your tires to make sure that they are around 32PSI for a passenger car. Check the inside of your driverside door for the correct PSI for your tires.
4. To check if your tires are balding, do the penny trick. If you can’t see Lincoln’s head, you’re good to go. If you see most of his head, you need new tires.
Also, I do not agree that this is a possible alignment issue unless your wheels are WAAAAY out of alignment. If this was the case, you would either have a hard time keeping the car going straight, or both of your front tires would have to be exactly offset in order to compensate for the other’s misalignment. I don’t agree with tie rod ends either. Bad tie rod ends will cause your steering wheel to shake, or cause result in sloppiness in your turns.

How to determine what pressure to inflate car tires to?
My Ford garage always deflates my tires everytime I take the car in. They say the tires need inflated to the pressure listed on the sticker on the inside of the door. But I say since the tires on my car are not the tires it came with that I should use the pressure rating listed on the tires.
Is there a general rule on finding appropriate pressure?
I generally take the max cold PSI and inflate to 90-95% of this number.
Let me know your thoughts. Thanks.
admin answers:
The pressure rating listed on the tires are the maximum for the tire. Do not exceed the pressure rating of the tire.
For the vehicles I operate, I inflate the tires to the pressure specified by the automobile manufacturer, given in the owner’s manual, and (usually) on a sticker on the drivers door or jamb.
Note that the pressure recommended by the manufacturer applies to the tire specified by the manufacturer, not to an “oversize” tire or a tire of a different aspect ratio.
The manufacturer chooses the the tires and the inflation pressure to get the best balance of performance characteristics (safety, comfort, handling) from the vehicle.
When my vehicles are going to be heavily loaded (not to exceed the GAWR or GVWR), I increase the tire pressure by an additional 2 or 3 PSI over the manufacturers recommendation.
If you have changed to a different size of tire, then follow the recommendations of the installer. (They have formulas for figuring out the pressures for replacement tires.)

Can the material used for aircraft tires be used for regular car tires?
Aircraft tires can carry heavy loads at tremendous speeds, unlike the regular car tires….so is possible for the material used for aircraft tires be molded into a size of a regular car tire and be used effectively for brakes and jumping cars over high heights?
admin answers:
The materials are in fact pretty much the same, but it is the design that is different. As others have explained, airplane tires would not work well on autos and they would be much more expensive than what you can buy now. I fly a plane with tires approximately the same size as a standard car tire and they cost over $600 apiece.
There are other problems. For one, aircraft tires are made to go at high speed for very short distances. You would not get very high mileage out of a car tire if it were designed like an airplane tire. For another thing, aircraft tires are not designed for the loads imposed when going around curves at high speed like auto tires are.
Auto tires are engineered and constructed very well and the quality has improved dramatically over the years. In the 1970′s, top-of-the-line Michelin tires were good for 40,000 miles with a top speed rating of 100mph and they cost about $100 each. Today, the best passenger tires can go 80,000 miles at speeds up to 130mph…and they cost about $150 each. Adjusting for inflation, they are cheaper today than 30 years ago, and they are far better tires.
