Moving from 18" to 19" wheels - what do I need to do?
Hi all - I'll be receiving my new 19" wheels shortly, and replacing the stock 18" 235/255 set with a 19" 245/275 set. I'm on stock suspension. I know I'll need to get the TPMS system setup, but do I need to necessarily do an alignment or anything? Or is this only necessary if I do run into some ride issues? I'm driving a '14 coupe. Anything else I should be aware of? thx

The only thing you have to do is to figure out the PSI's that work best for your area and to watch out for potholes. Other than that, keeping your wheels spotless will be a huge pain with the stock brake pads.

Thanks Jeff - why will keeping them spotless be more of a pain than it is already? My pads already put off a fair amount of dust, and my new wheels are going to be black (versus the stock silver) so I was thinking it might be a bit easier. Am I missing something?

I made a premature assumption in thinking that your wheels are brushed aluminum finished like the ones I have. I have to wash my wheels quite often.

Ahh, gotcha. I was going to get brushed stainless, but changed my mind afterwards to a black, so my car will be black on black (on black on black) . Super psyched to put these babies on!

I am surprised to see as many weights on there though! Good Grief!
I wonder if some of these companies offering light wheels are like:
"lets shave off some weight over here to make them seem lighter than the competition, then when the tire guy mounts the tires, he can put the weights on the wheels to get it right."...! LOL
I'm kidding... Kinda. Prob the tire manufacturer who has weight distribution issues.

I was wondering about that myself. It does look a bit obsessive. There are 16 weights on there. I'll have to look at the full set when I receive them and see what the weight situation is like on the full set. I guess I'm also wondering what type of balancing was done, and if road force balancing (versus plain old balancing) could offset the need for some of these weights, especially if some of the issue is due to the tires as you propose.

I assume the speedometer will be off slightly. On a similar note anyone do anything with the traction control? I have heard that the bigger wheels make it go off more often since it thinks the wheels are slipping.

Someone will probably chime in on this as I've seen multiple lengthy threads on this subject. My take is that the speedo will be off, but only very slightly. And my take on the traction control issue is that it won't be a factor, it couldn't be, since normal wear on any tire reduces the effective diameter just as much as a change in rim size from say 19" to 18", or whatever. That would mean TC would be freaking out as tires wear, which makes little sense, at least to me. Good questions, though. We'll see if someone sets me straight...

Nice Klassen
All you need is put them on and rollllllllll
If you feel vibrations at high speed you might need to re-balance them.

You should have no issues if the offsets are good.
If your alignment is currently good no change should be required.
Speedo will be slighty out to what it was. I used to read about 5kph out at 100 kph and it it is now closer to 3 kph (shown 100 kph is an actual 97 kph).
Seal the new wheels prior to installation with a good sealant product or even one of the premium nano/ceramic/glass sealers some of which are specifically packaged for wheel use - cleaning is much easier. I used the very modestly priced Finish Kare 1000 high temp sealant.

Ahhhh geez! That sucks bro. Well, at least you will have a "second opinion" on where the weights need to go and how much go there.... lol

That's true. I think the finish on the wheels (textured black) may have contributed, and so I'm going to give the wheels a good clean before the weights are applied too. I'm thinking I could've just plasti-dipped silver weights, but considering there were about 60 of them in total, and as I understand it you usually need weight on either side of the rim, that would've been a pain too, also to maintain. Not sure how it would've help up either.

Well at any rate, good luck to you.
