Suspected cause
The ride seemed more bouncey, I figured it was the tires.

Suggestion
Thats why I think it has a smoother ride....Not that my 18's were harsh at all, but I said nothing to my wife, who HATES driving the car, she loves our Range Rover and its smoothness....she drove the Porsche and called me and said, did you change the suspension?
Leading evidence: 'tires' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'tires' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Replace suspension' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
You won't have ABS issues since it isn't too far off in terms of diameter but you will not be running a better ride.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Is there a tradeoff for wheels being too light,19#'s, vs. stock weight 29#'s for strength and durability? I'm concerned about 19" champions being more fragile in regards to road conditions,potholes, and not being as durable as 19's with stock weight. Any info or experience would be app. JW
I am sure the Champion wheels are very durable but remember you just can't skirt the whole physics of fatigue on metals as well as strength in blunt impact. Not an exact linear relationship becasue materials, etc, cary vary but as you give up weight you give up strength. If you are just wanting to putz around town then no prob getting the 19's but you WILL have a rougher ride. You have decreased your sidewall as well moving up in rim size and no way around that either.
depends on the manufacturer and model. generally speaking, you want forged alloy wheels, which are much stronger than the conventional method of manufacture. even in the same manufacturer, strength can vary. i used to have 17" SSR Integrals (225/45/17) on an old bmw when 17's were deemed big. they were cold forged and indestructible amid nyc roads. in contrast, i heard the GT1's (dunno if forged) are very fragile. can't comment on champion wheels. best bet is to do a search with whatever wheel you're interested plus "strong," etc.
Well right and wrong....if he goes 997 tire sizes on 19's he will get a better ride....I have and yes I know its a bigger than the 996 sizes, but I have NO ABS issues and NO PSM issues....
Since we are on the subject, I have a couple questions regarding wheel sizes.
I have basically a stock C2 - no mods to speak of with good old 17". I'm really looking into pss9 + larger wheels and will pull the trigger soon.
I really like the 19" (I'd go for the "lobster claw" 997S rims prob), but I'm worried they would be a little too much on long road trips (loooong ones, across country). Are they, in fact, THAT much rougher than 18" or 17"?. I know they WOULD be rougher, but will they be uncomfortable on a looong trip? 18" seem like the "smart" choice, and I was wondering if anyone can comment on going from 17" to 18" on ride quality/noise/handling/etc.
Sorry I don't want to hijack the thread, but I figured this is all related.
How in the world will he have a better ride? Are you talking about the 296/30/19's??? You won't have ABS issues since it isn't too far off in terms of diameter but you will not be running a better ride.
With a coupe you may find the stock factory set up too severe for 19s. 19s came on mine (997S) and I appreciate the fact that I ordered a cabriolet,--the coupes would be too severe, I think. I have driven the thing on many roads trips and find the 19s to be just fine.
I dont know the "scientific" reasons, but my car has a better ride than the 18's period....Going from 285/30/18's to 295/30/19's I do have actually a 3mm MORE sidewall.....As well as 10mm more width. Thats why I think it has a smoother ride....Not that my 18's were harsh at all, but I said nothing to my wife, who HATES driving the car, she loves our Range Rover and its smoothness....she drove the Porsche and called me and said, did you change the suspension? I said no, why? She said, its soooo much smoother!....I thought it, she felt it. Now maybe it has something to do with the way the 19's work with the PSS9's, maybe its just a good setup....who knows, but let me say, my ride is FAR from harsh, its better than my car was with 18's on the stock suspension. Like I said, I have not done any scientific investigations, but I just know what I feel...I was completely expecting a more harsh ride, but it never came. I also got more crisp turning as well. To be honest I didnt lik ethe way my car handled with the 285s on the rear, I liked the 265s much better, it had less understeer, now with this tire/wheel combo i have even less understeer.
I commute 100 miles a day on SoCal freeways....no problems..I have driven to Arizona and back in the car with no fatigue issues and no harshness problems....
my wife hates the 18's on my cab.... when i got the 19's on... she still hates it.....i should ask her which one does she hates more.........or maybe it's just the driver.........?
yup..... she hates it when the convertable is down... well only at night she's okay with it, and anything with the car... she puts up with it because it makes me happy..... so she says.....
I second what john says.... I went from 18" with p-zero's to 19" with ps2's... don't know the science behind it, but I had to go back to arling and get the pss9's stiffer. The ride seemed more bouncey, I figured it was the tires. Everything is all good now...
I have 18" Champion RG5's on my 996, they are a very strong wheel. Keep in mind that these wheels are Forged and stock Porsche wheels are Cast.
Forging can produce a wheel that is lighter AND stronger (than cast). If you talk to the gents over at Wheel Enhancement they will tell you Champions are one of the highest quality wheels that they sell.
