Main reason is comfort, as I do enjoy the benifits that come with 18 inch alloys like the handling but unfortunately the roads I drive on are not as smooth so I do feel every bump.As long as they fit..........
I would consider moving from 18" to 16" wheels if this results in significantly less road & tyre noise. Pease post whether you notice a significant reduction in noise and what wheel tyre combination you used.Main reason is comfort, as I do enjoy the benifits that come with 18 inch alloys like the handling but unfortunately the roads I drive on are not as smooth so I do feel every bump.
Just a few weeks ago my brother gave me a lift in his 10 year old clio (with 16 inch alloys) and i could swear that it was a smoother ride than mine!!
I've had the car over 2 years and love it but its the only thing that always anoys me.
I will keep hold of my 18 inch wheels and try out smaller alloys.
I will probably buy the Mazda 16 inch alloys hopefully they should be the same diameter
Yes, I have the 18" wheels with Dunlop Sport Maxx TT tyres. These are noisy despite having a good 68db EU drive by noise rating.In the UK the Sport model is the top of the range and come with 18" alloys, the lesser models are the SE and SE-L which come with 16" alloys.
Actually the reasons they came about is more like so real race cars (think F1 or Indy) could have 12" wide tires and still stay within the maximum wheel diameter rules. Running 12" wide 60 series tires just won't do. :smile2:Well, I concede that for competitive racing cars on smoothly consistent tracks, big-wheels / short sidewalls make sense in terms of superior handling. That's why they were designed in the first place, with wide treads and short sidewalls that don't distort as much around corners and at high speeds while competing on the track.
But by the same token, big wheels / short sidewalls don't yield as well when striking potholes and curbs in real-world streets. So for street cars, they aren't so beneficial, because attempting to realize any difference in handling on the street normally would be dangerous. I.E., trying to take advantage of the ability to go around curves at over-the-speed-limit speeds is a dangerous thing to do on public streets.
There is no difference in brake hardware, same calipers and rotors.I'd advise extreme caution here: it's possible 16" wheels may not fit. I'm not sure, but the brake hardware may be different for the cars that came with 18" wheels than those with 16" wheels, and in that case, the factory 16" wheels may not clear the brake calipers. I advise looking through the parts lists on someplace like tascaparts.com, and comparing the brake parts between the 'i' models and 's' models ('14-'16), to see if the brakes and the suspension arm the brake caliper bolts to are the same or not.
If you want to downsize, a safer path would be to get some 17" wheels; I've seen several people on this board downgrade to 17" wheels on their 's' models for the same reasons you list, so I'm sure they'll fit. It's not as big a difference as with 16", but it's still significant.
Yes. It means the rims with the smaller bore won't fit the hubs with the larger bore. Assuming of course the rims have bores that match the hubs. So, they will not work.I have a question about center bore, Honda/Acura Civic/RSX has a smaller center bore than mazda, 64.1mm versus Mazda 3's 67.1mm, a difference of 3mm. Will that become a problem for fitment if I wanted to use some Honda/Acura rims on my Mazda 3?
Machine shop to bore out the rims to fit the Mazda hub? Might be able to find a connection thru my local autocross club to have it done cheap enough that its worth while.Yes.
