While I believe the tire shop gives free rotation to get you in the habit of coming back to them every few months so they can sell you more, it can be important to rotate your tires. It all depends on the wear of the tires I have had sets of tires that wore extremely evenly and I only rotated them once. Other sets of tires I have had wore very unevenly ...

My wife had a similar problem on her car and it turned out the problem was the wheel, not the tire. We'd had enough sand and salt on the road this winter that she had corrosion / gunk building up right at the bead. The tire shop dismounted the tires, cleaned up the seating area on the wheel and then remounted the tire. The problem now seems to be solved.

Personally I wouldn't drive on that tire - if it delaminates while you're driving you're risking a blowout. You get bulges like that if the rubber basically separates from the various reinforcement plys in the tire and as the air in the tire heats up from driving, it'll slowly expand. All it takes then is something that pokes/cuts the bulge to turn your car ...

The tilt of the wheel is known as the camber angle. Tilting the wheel in that manner is called negative camber. Doing it the other way around (top outwards) is positive camber. Mounting the wheel with a negative camber improves grip under hard cornering as it counteracts rolling. On a completely level tire (0 camber), when a horizontal force is applied ...

Remember that lug nuts are exposed to literally every element that could possibly cause corrosion. It sounds like your last nut is stuck due to some rust or oxidation that you can't see. Here's how I generally approach a badly stuck nut: Check your safety gear: eye protection, jack stands, everything to keep yourself from getting killed when this wheel ...

Or is it fine to even go a little bit on the highway for a few days before I replace it? No. Please don't drive on that tire. You are seeing a large scale deformation in a portion of the tire that's not designed for point stresses like that. There's pretty clearly a thin layer of rubber standing between the marginally acceptable and explosively ...

tl;dr: No. This sort of vehicle dynamics question best addressed by Racing Car Vehicle Dynamics What follows is a basic discussion at the high school physics level. As you will see from the reference text, high school physics is insufficient to statically model the complete vehicle system. A dynamic model is required to agree with easily obtainable ...

The reality is that snow tires live in a world of wet snow and salt. That's about the worst possible combination for corrosion. Your best bet in that situation is to dilute the salt-water solution, usually from straight water rinsing. Any remaining risk of corrosion will have been greatly decreased by your rinse. My inclination is to rinse off the tires ...

Winter tires in Winter and Summer tires in Summer. With very rare exception the "All-Season" tires are really only very good for 3-Seasons, or for places where the roads are always kept clear in the Winter. Do all 4. Having a mix of Winter/Summer tires will adversely affect handling and braking.

You can calculate the size of the effect from simple geometry. Tire wear reduces the diameter of the tire, which reduces the circumference of the tire. New passenger car tires typically come with 10/32" to 11/32" of tread depth (source). Tires are considered fully worn-out when only 2/32" of tread remains. So the tire has lost 8/32"--9/32" on the radius, or ...

First, the critical caveat: You are the driver. You have to make the decision. It ultimately doesn't matter what we say. Given, that, I would say NO, it is not safe to drive until the weekend. Get the broken tire fixed or replaced as soon as possible. You have two problems: Top speed limitation: the donut is top-speed rated for 50 mph (check the ...

The Info provided by COSTCO is on paper correct, if you were say using a tire with a speed rating of 118 mph (T), and you were in Germany cruising at 140 mph, the tire could overheat and cause this problem. However, in your case, you just had a flat tire driven on flat. If they check the tread, area, or the valve stem, from the take-off tire, they will ...

Yes, wheel chocks would help in this case. Also, use of the emergency brakes as well as leaving it in gear (EDIT- Leave it in gear if a manual or park if automatic). If wheel chocks are not available, you could use a largish stone which could be wedged between the tire and the ground on both sides of the tire. This would be on a tire which is not flat and ...

Yes! They have lug nuts. There is a center cap which is removed to access the lug nuts. Center Cap Wheel

Tire condition can be interpreted in several ways, visually being the most prominent. Usually excessive tread wear can be seen quite easily using the famous penny test (using an old penny, one where Lincoln's head doesn't overlap the outside edge of the coin). From Wikipedia: If part of Lincoln's head is covered by the tread, the tire has a legal ...

There are three common methods.The first is to buy a tread depth gauge which measures tire tread in 32nds of an inch. The general standard is 3/32's minimum.The second is a penny. Insert Lincolns head into the tread,if the tread does not hit Lincolns hair it is due for replacement. Do this test in five different spots,if two are not hitting the hair replace ...

There are major benefits on a track: you have much lower tire deformation with a low profile tire so you can corner harder. You can also accelerate and brake harder, and your tires get to temperature much faster as there is less rubber to warm up. On a normal road having very low profile tires can be a negative - they don't soak up bumps as well as a higher ...

Any tyre design is a balance between cost, grip, longevity, water displacement and rolling resistance. Change one, and chances are you'll adversely affect the others... Personally, I would always put grip and water displacement (which affects wet grip) above all the others on a priority list. The difference between those "fuel efficient" tyres and normal ...

From what I have seen and read over the last few years the "general rule" has become best tires on the rear. In my opinion it is likely the result of litigation by people who were involved in skidding accidents. The theory as far as I understand it, is that with worn tires in the rear, the back end can loose traction and allow the rear of the car to attempt ...

I second Gabriel's comment: Probably cost. Nickel Moly Chromium Stainless (316) is very expensive, this random kitchen sink is just a sheet of stainless stamped into a cube, and it's $500+ retail. Given the price I have to assume it's 316, otherwise it would be even more. I can only imagine what a single wheel would cost a manufacturer. Even using Powdered ...

Largely because it's unnecessary. Steel wheels are so incredibly cheap compared to stainless that there's no benefit. Steel wheels are heavy enough that it takes way beyond the normal life of a car for them to rust out too (I have a 22 year old car that I drive in the winters on original steel wheels and the wheels are in better shape than the car body). ...

The answer is NO. It is never a good idea to replace a single tire, because each tire has different performance characteristics. You may not notice it during day-to-day driving, but any non-ordinary actions, such as swerving to avoid an accident, turning or braking in a rain storm, etc you may suddenly find the car doing something completely unexpected. ...

Not sure what damage might happen to the diff, but on the front axle this might cause the car to pull one direction or at least create extra stress due to one wheel gripping differently than the other side. I would suggest replacing the tires in pairs. Although if you only had a couple thousand miles wear, then it might not be a big deal.

Due to materials used and design, they tend to overheat and fail. Winter tires are also typically not speed-rated like Summer tires (since they can't handle the heat of higher speeds).

Apparently one of the car wash employee accidentally put the truck in 4x4 high when cleaning the dash. I didn't notice the indicator and the locking diff was causing the change in handling

There are a number of things you can do to unstick the nut before turning it: a lubricant or rust blaster. Keep things wet and give it time to work. heat cycling. Heat it up (gently) and let it cool. Repeat. If you oil it up and point a propane torch at it, you may start a fire, so be careful. It's not so important to heat just the nut or just the stud - ...

In some jurisdictions (including my own), driving with a tyre looking like that is illegal. There is a question about it on the driving test, and all such academic questions on the test are about things you must do, lest you be found to be in charge of a dangerous vehicle.

Following answer assumes you've got tires with directional thread (if you flip the tire 180 the pattern will mirror upsidedown). Among other duties, tire threads are responsible for "pumping" the water out from below the wheel when you drive through it. If you reverse the directional tires then the water will be pumped to under the wheel, effectively ...

This looks like damage from being run flat or with very low pressure. If the handbrake turns were all done turning in the same direction and the tire had low air pressure the sidewall would roll and rub in the turn. The damage would be confined to one side. I would replace the tire. The sidewall has damage. Any significent damage to the sidewall is like a ...
