265/35s on S5 rotors on S4

[Sfbimmerman]

Read a lot of threads of good and bad experiences with 265s on s4s...I have a 13 s4 that I’m gonna put s5 et33 rotors on soon..looking at lowering the car 1 inch and running 265/35/19s...anyone running a similar setup or have pics..?

Thanks
Paul

I run 265/35 on 19x9 Et 34 on a stock suspension, rubs on large bumps.

It runs on stock suspension?
What did the s4 came with for OEM wheel and tires?
I have an s5. 2015 with black optics or whatever they called it back than, it came with 255/35 on 19s

My wheels are 19x9 Et 34. 265/35/19

Stock S4 is 255/35/19.

I have s5 rotors but currently stripping those to repaint.

It "could" work but depends on tire choice. The B8.5 had a higher rear suspension/ride height than earlier version. The S5 wheel is 10mm further out than S4. A 265 tire adds another 5mm so total is +15mm. On my 2015 S4 lowered with stock wheels and Michelin AS/3, I have very little clearance at the lower rear edge of back wheel opening. I don't think I could get a et 35 and 265 not to rub. A Continental or other brands that have a "rounder" sidewall could work....but I think it would be tight.

Here’s my setup with 265/35/19
Wheels are 19x9.5 et 40
Lowered on oe H&R springs
Love the meaty setup

how low is that? 1"?

[Ecinka87]

Not that low enough to fill in the wheel gaps. Pretty stock feeling ride too

I'm looking to getting some lowering springs. Just cant decide on the OE or the sport

It’s actually more complicated than that. Since the width of the wheels is also different the amount the setup moves out is more than +10mm. Between a 19x8.5 et43 stock S4 wheel and a 19x9 et33 S5 wheel the wheel alone accounts for a 16mm more aggressive setup. Adding a wider tire will further add to the problem. Many people have rubbing with a 255 on the S5 wheels and a lowered suspension. I would say stick with the 255 especially if you plan to run a historically wide or square shoulder tire like a Michelin PS4S.

Ecinka87, thanks...your setup is pretty much where I want to be...figuring 19 x 9 s5 et33 rotors with a 265/35 tire should work well. Going coilovers soon I’ll probably do the tires at the same time, thinking Firestone Firehawks

It’s going to rub on large bumps or with back seat passengers.

Thanks Artic Silver, I see your point...gonna throw the S5 rotors for a little and burn through the tires...I figure that’ll give me a good eyeball at what a bigger tire could look like...

[Ecinka87]

Go with the OEs good drop stock feel

Sports. Too much wheel gap with OE

[Ecinka87]

Choose wisely on tires. All tires are different specs. Like tread width and sectional width. So if your planning on 265s just pick out the smallest spec. That’s what I ended up doing. Just FYI

are you running hub adaptor? 72.6mm hub bore? point me to the right direction.

Ecinka87, what tires are u running...I want to run 265s but with my 4 cars, I gotta keep the budget at $200 a tire or below...

The only tire worth using in that range is the Firehawk Indy.

At ~25.5” fender-to-ground front and rear I had some rubbing with 255/35-19 on my 19x9 et33 S5 spec wheels. I think 265 would be problematic.

[Ecinka87]

Yes 72.6 to 66 hub adapter

[Ecinka87]

Yokohama advan apex actually is the smallest 265 tire you could use. I have checked all of them or the Michelin pss mo spec.

[Sfbimmerman]

Wow, SteveYem, I know the s5 rotors stick out a little more, guess the 265 will be too much plus I want to do coilovers in bit too, but just an inch drop...255s will be fine....I’ve ran Hankook v12s before, might go back to those or the Firestone Firehawks Indy 500 I’ve heard good things about..

The face of the 19x9 et33 S5 spec wheel sits farther outboard than the stock 19x8.5 et43 wheel by approx. 16.3 mm, which is the difference in offset (+10 mm) plus half the increase in width (12.7mm (half inch) divided by two, or +6.35 mm). The position of the tire is determined solely by the offset (since the tire is centered on the wheel), so relative to the stock 19" setup the tire will sit 10mm farther outboard. The 9" wide S5 wheel will induce relatively more stretch on a given tire than the 8.5" wide S4 wheel which can help with fender clearance. This is especially evident on 9.5" wide aftermarket wheels with stock size 255/35-19 tires, and the stretch on the sidewall provides more clearance to allow that size tire to clear the fenders at lower offset applications.

Anyway, all of that said - pictures tell a thousand words. For reference, here is a set of S5 19x9 et33 rotors with Michelin PS4S 255/35-19 tires. Ride height is around 25-3/4" fender to ground front and rear. I had some rubbing at the rear passenger side but not the rear driver. [This is because the rear subframe is not centered relative to the body/fenders, a common issue with B8/B8.5 cars which only because obvious when running more aggressive wheel+tire setups that get close to the fender.] IMO, 255/35-19 is the 'right' size tire for this wheel. Depending on the tire brand and type, there is just a little bit of sidewall stretch but the tires fill out the wheel wells nicely.

I’ve never had an issue getting anywhere. There’s about a half finger gap in the front and one in the rear. Looks great rolling

Is there any problem running 265s on stock S4 19” Peelers with stock suspension?

I just want a little more visual width..

Stock S4 peelers are 8.5 width. I ran Pilot Super Sport 255/35/19 on stock peelers and the sidewall sits pretty square. (i have heard the PSSs are a tad squarer than some though) I think a wider tire on the S4 peelers would look weird.

I wanted a fuller appearance with the S4 peelers and got the ECS spacer set (8mm front, 12mm back) and I thought it looked a lot better. I would do that first before getting a wider tire on the 8.5s. Are you lowered?

Thanks. Not lowered. I like my suspension for the moment (while it functions)..

I have 5mm and 10mm spacers currently. Even those improved the stance. I did not want to go crazy but am now wondering if 8/12 would have been better. Are the ECS 8s concentric..? My 034 5s are not and I have slight balancing issues that I need to try to work out.. Or I buythe ECS 8s.


But really I am now looking for a wider TIRE look. I think S5 Peelers are probably the answer..

[TC_S4]

I need to change tires this summer, want to go 265/35R19 (Indy 500) to get a wider look but don't want any rubbing. I have S5 5 double spoke wheel 19x8.5 ET32 with stock suspension. Is it a good idea?

Im stock and only rub on big bumps, 265 Indy 9” and et34. I think you should be okay.
