Advice on putting new alloy wheels on car?

If my car has 16'; alloys as standard, could I fit 18'; alloys without having to alter anything?Advice on putting new alloy wheels on car?
Yes as a rule you can go about two sizes bigger, but you'll definetly need to run a low profile tire or it will rub your fender wells. It will probably throw your speedometer off just a couple of miles per hour.Advice on putting new alloy wheels on car?
depends on what kind a car you have, but my car came with 16'; out of dealers i run 18';s and i can put 19';, but the same model car also comes with 18s out of dealer

It depends on the profile of your tyres.


If you have 55 or 60 profile tyres, you will be able to get lower-profile tyres to keep the same effective rolling radius with larger tyres.


If you already have very low profile tyres (e.g 40 profile) then it is unlikely you will be able to fit a larger-diameter wheel.
it should be ok, make sure the whole wheel including the tyre is the same size as the standard ones or it'll mess up and your speeo wont show the right speed (not good!!)
No. For one thing, you will find the wheels rubbing on the wing when you are on full lock. Secondly, you have to notify your insurers that you have modified your car and also notify the DVLA of any changes to the the manufactures specification. There is a possibility that it can put more strain on your steering rack as well.

Most likely you should be fine. Check tirerack.com and size them up. Remember the more weight you add to your wheel then is stock is going to cut into your gas mileage. It will also effect power off the line. That being said good luck I've bought 6 different sets of wheels for my cars and always think it adds a great personal touch.
It all depends upon the wheel dimensions.


The stud pattern must match the cars studs.


The inset of the rim (the measurement between the inner edge of the rim and the centre of the rim) must be the same as standard or else the rim or the tyre may foul against the suspension.


The outset of the rim (the measurement between the outer edge of the rim and the centre of the rim) needs to fit within the wheel arch to stop the tyre fouling the vehicle body.


Non-standard sizes may fir but they will put the wheel bearings under strain.


The tyres would have to be very low profile if the speedometer is to remain accurate. Remember that the bigger the diameter of the tyre the bigger its circumference, so it will take fewer revolutions to cover the same distance as a standard tyre (the distance covered by one revolution of a correctly inflated tyre on a rim under normal load is called the rolling radius).


Speak to an expert company like RipSpeed, they can give you all of the information you need.
If the tyres are any wider you will have to check you can go from lock to lock without the tyre rubbing the wing or inner wing. Also remember that if the circumference of the new wheels and tyres is bigger than that of the old your speedo will be out. If you do fit alloys remember to put ';copper slip'; on the hub flange before pulling up the bolts or nuts.
