I bought two new tires and rims to put on my car and I want to know if I can make them fit.

I just bought new rims and tires for my car they are size 225/45 zr17 and the tires size is supposed to be 205/55 r16. The rims fit over the tire threads but I don't know what size lug nut to get I can't fit a socket in the rims for a retailer 19mm or 3/4 I want to know if they make a lug nut that will fit in the rims like maybe a 9/16 lug nut but will still fit over the threads?

My car has 204567 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hi there. Anytime you purchase new tires and wheels that are not OEM options (which this 225/45zr17 is not), you risk creating multiple issues that will impact the vehicles performance such as ABS operation, speedometer, cruise control, and braking.

The standard rule used to be, for every inch in wheel size, you need to decrease aspect ratio (the 55 number) by one (making it a 50-series tire). Width would also increase by one size (to 215 from 205). By having a wider tire on there than is recommended, you also risk having turning radius issues and braking suspension components.

Due to these facts, I wouldn’t recommend putting those wheel and tires on your vehicle. If you were to install them, you’d need to purchase new lug nuts that are snug for that individual bolt pattern. Since we can’t see them; it’s impossible to tell you for certain if the ones you have will work.

How to Identify and Fix Common car Problems ?

Put simply, to find if your wheels will fit your car, measure the distance from your wheel`s center point to where it is mounted. This is the offset. Add that to half your wheel`s width to find the back space and subtract it to find the front space. Compare this to your wheel well to see if it fits.
While you may be able to get away with using various brands and models, using different sized tires and wheels can lead to accidents and expensive maintenance issues. Mismatched tires and wheels put constant stress on your vehicle`s suspension and transmission, along with your brakes and ABS system.
How to make sure that rims will work with tires? Width and diameter are the two factors that determine tire and rim compatibility. For diameter you`ll need to be sure that your tires and wheels are an exact match, e.g. a 215/65R17 tire will only fit on a 17″ diameter wheel.
As a general rule of thumb, it`s safe to fit a tire up to 20 millimeters wider than stock on the original rim. The actual width of the tire will vary depending on the width of the rim: The tire will expand 5 millimeters for every half-inch (12.5 millimeters) increase in rim width.
Find the information in your vehicle owner`s manual in the glove compartment or on the tire information sticker on your driver`s side door. Usually those elements contain all the information related to your tire size and specifications as well as the appropriate tire pressure.
It depends. Wheels and tires are not interchangeable words. Tires are a part of the wheel setup. For instance, your vehicle has a set size of rims, but you can buy different sizes of tires to fit those rims, as long as the middle of the tires is the correct size.
Having two different-sized tires on the same axle is generally not a good thing. If the diameter of the two tires is close, then the rolling radius is about the same, so in the short term, you probably won`t have any damage, but long term, you run the risk of messing up your car`s differential.
If they`re too big they can cause clearance problems inside the wheel well, and when turning, the tires may contact the fender liners creating an ungodly noise and limiting steering movement — not something you want if you ever have to pull an emergency maneuver.
Identifying Compatible Tire Sizes

The first is in the driver`s door jam. Open up the driver`s door and look within the door jam or on the door itself and locate the sticker that has your tire information on it. Here you will find the wheel (rim) and tire size your vehicle came equipped with from the factory.

For most standard tire sizes, the optimum rim width factor is between 0.8 and 0.9 of the tire section width for ideal performance and if the tire is used with lowest inflation pressure. For normal usage, tires work properly on rims from 0.7 to 0.95 of tire section width.
No. There are a multitude of ways that one wheel can differ from another. Some are steel. Some are cast aluminum.

Hello I recently hit a pothole and damgaged a rim I had. I had to replace with all new tires and rims. I first got stock rims then
ANSWER : A road force balancer is meant to check tires for pull in one direction or another and balance a tire up to about 60 mph. Some tire balancers will check tires for higher speeds. You may have an imbalance that most machines cannot measure if it comes in after 65 mph. You can see if there is a shop near you that can do high speed balancing? You may have a front axle that is causing the vibration also. I suggest installing the original rims and tires on the front only to see if problem is still there and if so have the front axles checked for damage and replaced if any damage or looseness is noted.

I bought 4 hankook tires in the size of 205/55/r16 to mount on my front wheels. How do I know if they will fit?
ANSWER : Hi and thanks for contacting Your Mechanic. There are a couple ways to determine if the tires will fit on your vehicle. First look at the tires that are currently on the vehicle and see what the tire size is. If the tires size is the same, then yes the tires will work. If the tire size is different, then look at the first number and the last number. The first number determines how wide the tire is. The last number determines what size of rim the tires will mount to. Make sure that the last number is the same. The middle number is for the sidewall type and this determines how good the vehicle will handle and ride on roads in different road conditions. If you are not sure that the tires on the vehicle are the size that you need, then look at the door placard on the driver door or on the mounting area by the driver door on the cab and you will see the tire size required by manufacture. If that label is not present, then look in the owner’s manual for the tire size. If you need further assistance with determining the correct tire size for your vehicle, then seek out a professional, such as one from Your Mechanic, to help you.

Advice for winter tires
ANSWER : 205/55R17 may be too tall for your vehicle. A couple of good sources to check size compatibility for your vehicle would be tirerack.com or maybe discounttire.com. Sites like Tire Rack specialize in winter tire packages and is a good source for fitment options. I have personally used Bridgestone and Dunlop snow tires and would recommend either. However, it is highly recommended that winter tires be mounted at all 4 corners. Having different tires with different capabilities not only makes the vehicle unstable, it will effect systems like the anti-lock brakes and traction control. Winter tires perform much better than summer or all-season tires do in ice and snow conditions. Having two tires with good winter traction and two with poor traction will have the anti-lock brake system working overtime. Also, sticking with a smaller tire for winter use is advisable. For ice and snow driving, you want the opposite for summer driving. Wide, low profile tires improve warm, dry weather driving. Tall, narrow, tires provide better control on snow and ice. Consider keeping your stock 16 inch wheels for winter use with winter tires mounted on them and maybe a nice set of 17 inch wheels and tires for summer use. I’ve done that with nearly every vehicle I’ve owned whether front, rear, or all-wheel drive.

Car pulls to the right after tire rotation
ANSWER : Hello. On your 2002 Mercedes Benz SLK320, all of the tires have to have the same tread design an the same amount of tread. Any variations will cause the computer to not read the sensors correctly which will cause these issues. You need to purchase two more tires that are the same as the new ones, and install the tires to replace the other two tires. If you want to have this looked at before replacing the tires, a local expert from YourMechanic can come to your car’s location to diagnose your car’s pulling issue.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you

My car cranks but will not start. I try to do fix the car myself. I put new battery, new alternator, and new ignition coils.
ANSWER : Hi there. Check the spark plugs and see if they are worn or burned. If the plugs are good and they have a good spark, then the engine compression could be low causing a no start situation. If the spark plugs are not emitting a spark, then the crankshaft position sensor could have failed or disconnected. Check the crankshaft position sensor wiring harness and make sure that its plugged in. Check the sensor and make sure that its not broken or damaged. If you need further assistance with your engine not starting, then seek out a professional, such as one from Your Mechanic, to help you.

Knocking from front right tire after getting a flat and putting a new tire and rim on. 2003 Olds Alero
ANSWER : Hi there. Chances are the noise heard from the right front wheel is the result of the replacement rim and tire. This may not be safe to drive and should be corrected, before continued driving. If the rim is correct by application, double checking the lug nuts for proper tightness would be a good place to start. Something may have bent with the impact to the curb. Proper diagnoses should be performed to avoid unnecessary repairs. I recommend having your vehicle’s knocking as the wheel turns be diagnosed and repaired by a certified technician, such as one from YourMechanic.
