Running 265/35/19 tires w/lowered suspension? Worried about curbing 19x9.5 wheels.

[philbegas]

I'm about to pull the trigger on some 19x9.5 et25 wheels for my RS4. I'm fairly lowered on Billstein PSS9 coils w/no fender modifications. I don't want to run 265/30 tires because those will offer significantly less protection from philly potholes/roads. I have the following concerns:

- If I run the 255/35/19 size will it be a lot easier to curb rash the wheels?

- Is the 265/35/19 size likely to run into issues rubbing over bumps and at full steering angle?



- Running 275/30/19 is also theoretically a possibility, but also some concerns about less pothole protection.

If anybody has photos of 19x9.5 on 255/35 tires that show the lip protection that would be helpful. Also, if this is also dependent on tires, feel free to point me to 265/35/19 summer tires that should be the ideal fitment.

Edit: If it matters, I collected some stats from tirerack on their best rated max high performance summer tires:

Yokohama Advan Apex V601:
Section Width = 10.6
Tread Width = 9.0
Overall Diameter = 26.4

Continental ExtremeContact Sport:
Section Width = 10.7
Tread Width = 9.4
Overall Diameter = 26.4

Michelin Pilot Sport 4S:
Section Width = 10.7
Tread Width = 9.6
Overall Diameter = 26.3

If I understand this correctly, the exact tire specs will have a huge influence on rub no?

I'm going to respond with some info I got off AZ, so people don't have to repeat themselves lol.

There shouldn't be too many fitment issues running a 265/35/19 setup, but I may have to raise the car a little bit, as the rolling diameter will increase obviously, and I want to avoid rubbing under full compression if possible. I may also need to remove the top fender liner screw, which is not a big deal for me. I'll make sure to report back with observations.

I currently run 265/35/19 on et30 10's and I'm good. You'll be good with your 255/35 on 9.5s

I went with 265/35 to get my speedo a little closer to being accurate. I noticed while GPS'ing myself somewhere that my speedo was 5mph throughout the speed range.. Now it's only like 3.5.

Different brands of tires will have different dimensions per given size. All these pictures are with Conti DWS tires, my preferred tires for over a decade.

Aren't you the one who had fitment issues with the Neuspeed RS10 wheels? I was so close to pulling the trigger on those because I love the look. I wound up buying a set of Enkei RS05RR 19x9.5 et25 wheels instead. Enkei USA said that they talked to Enkei Japan's engineering department and they said fitment would be fine.

Rse102. Maybe? I wouldnt call it fitment issues, I just needed a 3mm spacer up front to clear the caliper. This is a mass produced off the shelf wheel, wasn't surprised nor turned off by it.

Some updates for anybody curious:

My wheels have been mounted along with 265/35r19s michelin PS4s. I am currently at 25.5 inches high all around on my PSS9s, and they had to trim my rear fender liners a bit where they were rubbing, but now the rears are fine. I do, however, have a little bit of rub on the front when driving over dips in the road, or when hard braking up to a sharp turn, any thoughts on where that might be? My front fenders are not rolled.

Also, does anyone have a photo of the front fender screw that I may have to remove?
