275’s on an s4

[projectwoopass]

I want to create this to try and accumulate as much information as possible for anyone who wants to run 275’s on our s4. I know theres a wheel fitment thread and I’ve been through the pages multiple times. I’d just like to gather as much information as possible from actual people running this setup. Please post wheel specs, tires size, alignment spec, fender modifications, and whatever else you had to do to make them fit and work without rubbing. I’d like to run 275’s as they are more common and easier to find than 265’s and offer more traction and grip’ but obviously will need some help to make them work and are cheaper than 265’s. So if anyone has some experience and would like to share it please post.

Thanks,

Woopass

It would’ve been nice to get oem flared fenders. I’ve ran 265, but would love to slap on 275 on 18s tbh.

I thought there was an s4 on here running 275 maybe 285 even but he had wide fenders. Maybe someone else can chime in, it's the red s4.

I went with 255, I got a killer deal on my tires, so went with the cheaper option

[Trent212]

There is someone running 305 or 315s on their S4 that rhey take to autocross all the time.

If I recall he has 345’s and it took a lot of work to get there.

[projectwoopass]

Im just looking at 275’s for now as it seems to be a popular size up from the 255/265 and from everything I’ve read doesn’t take too much modification to make it work. Everything else outside of this appears to take alot of body work and other modifications to make work without rubbing.

I ran 275/30/19 on a 19x9.5 et45 rim and had no rubbing
It depends on what brand of tire also.
The 275 were Firestone firehawk indy 500 they had more of a rounded sidewall/edge
I recently just took off p4s 265/30/20 on the same brand rims same width and offset and they rubbed around corners and big bumps.
If your going 275 just check that the tire isnt a straight edge design.
Im running Toyo proxy now and they have a similar sidewall as the Firestone did

Thank you for the info s4matty. My goal is to collect all the first person experience from people like you who have ran these setups and keep all the information here for future people who’d like to run something alittle wider than whats considered the normal “safe zone”

[friskuh]

why not get pulled fenders? very slight pull,maybe 1/2 inch should be enough for 285s

[projectwoopass]

Friskuh,

I’ve actually never heard of this. Do you have any links for someone thats already done it and what they had to do in detail?

I'm running 275/30x20's with 235/35x20 on the front with Zenna UHP tires and STR 607's 10.5 rears/ 9 fronts. I had the rims machined and they tuck in nicely but the rears still rub a bit on big dips n bumps. I have the KW HAS springs as well and it's lowered 1/2" on the rear and 1" on the front. The required minimom depth of the seating surface for the studs is 6mm on the rim. I'm going to see if I can get a couple more mm's taken off the rears and with the Zenna UHP tires (they do have a stretched look to them), I think I should be ok as long as there's room so I'm not rubbing on the bump stop cover. The pulled fender sounds like an option as well, wonder where that could be done?

You can run a 275, look for a tire thread width around 9.4-9.2 but do your research, the lower that # is, the side wall look / \ and give you clearance. The higher tread width number =square set up [ ]. Also run some - camber on your alignment for clearance on F&R.

I think the Michelin are like 10” wide in a 265, why look for a 275 that’s narrower? Do you just want to say you are running a 275?

i run Michelin PSS 265/30/20 on 20x9.5et38. my tires tuck in the back due to the angled fitment of the tires, but i only rub on big dips on the highway. i'm going to raise the rear about 1/4" and should be fine. If i took off my spacer (5mm) i'm pretty confident i could run 275s without issue (et43)

they're not really stretched, its just the shape of the tire and the way the rim protector sticks out
not positive of the alignment specs, buit nothing fancy. they are as close to OEM specs as possible and i do not have adjustable control arms

[cspcrx]

what number are you trying to chase? Is it 275 you want or a larger contact patch. I am running the widest PSS 265s they sell and I am amazed at how much the tread with varies. You may find those are the numbers you want to focus on vs the 275, 265. You could run a 275 that has the same exact tread width as a 265 but has more stretch in the sidewall, why unless you plan on running a really wide rim.

[RWD2quattro]

^^ Bingo, that's why I said look for a tread width with a lower number which gives you that stretched side wall look to clear fenders on a 275. If you run anything higher than 9.6 tread width you will rub regardless of set up unless you roll fenders. All tire manufacturers have different tread width, I selected my 265/35/19 PS4's with a 9.6 thread width on ET42 for square fitment but you can also get a narrower 9.4 or 9.7 or as high as 10 depending on manufacturer. As an example PSS tire 265/30/20 has a thread width of 8.9 (narrow) vs PS4S of 9.4.

So the main reason I’m looking into this is
a- the cost for 275 tires are less
B- 275 tires are more common and easier to find in many styles and brands than 265
C- yes contact patch does play a roll and 275 offers a bit more than 265 depending on the tire and brand of course.

The main reason for this thread is for people who have experience with this setup to post how thy did it and some of the issues that arose from it. I dont see why people are getting so bent out of shape about this??

Thanks,

Peter

The price difference is less than $10 and the load rating goes down. The ps2,pss ps4 and firehawk indy all are readily available in 265/35/19. Just saying. Good luck with your decision, if you are in a place with a lot of rain I’d make the ps4 my last choice, that’s just my experience.

Peter not bent out of shape at all, not sure how that came across in my message. Not my intention just trying to help.

Good luck with what every you go with.

[heartmys4]

I'm running Michelin PS4 275/30R19 wrapped around a Signature SV104 19x9 ET43. I'm using the H&R RSS+ coils at the highest settings, which results in ~1.25" of drop. Camber is set to -1.9° up front and -1.8° in the rear.

I have zero rubbing all around. If the front fenders were rolled and upper fender liner bolt shaved down, I am positive I could run a 19x9.5 ET43 without rubbing. However, realize that the RSS+ is a VERY stiff suspension, and there is less travel than other setups.

This depends on the tire for the cost and last I checked the firehawk indy was on an insane backorder for 265 along with most other tires I searched for. Yes yes I know some people can wait months for their tires but I cant. I was merely asking for information on what it takes to run a 275 as I know a 265 will work without much hassle...

Thank you for the information! And thats good to hear. How is the ride quality with the 30 sidewall and stiffer suspension?

NVH hasn't changed much at all that I can tell. It is pretty jarring and uncomfortable over steep speedbumps and potholes. If you live in an area with deteriorating roads, I don't think I can recommend it. Where I live the roads are pretty decent, and I'm young and can still tolerate a stiff ride.

Yep I did it too. 275/35/18 RE71R on 18x9.5et45. They run very wide. I rolled the fender liner screw tab in the front. 3.5° camber in front. Max in rear ~2.7°. I was very low too with no rubbing issues whatsoever.

As someone said above, I’ve since abandoned this setup and gone to 345s all around. If you can fit those, I highly recommend it :)

Thank you guys for the information. JD, Jays car is more of function over form. He has been testing many things as of late to find out what works and what doesn't. I doubt he just tossed the wing on to be "in with the crowd". If it doesn't work I'm sure he'll pull it off and run something else.

I’m trying to be “in with the (times of the) Street Modified crowd”.

I.e. trying not to lose to Subarus, Evos, and that one 240.

I run 275/30/19 continentals on 19x9.5 et40 wheels.. I'm stock height so it obviously doesn't rub but it looks stupid as hell, wheel gap is massive LOL...

I have them on because i got the wheels second hand and the rubber still had some life so I am riding it out. I will probably end up lowering the car and going back down to 255s, I dont see the appeal of the wider tire, also these are loud as hell on the highway.

[TikKToc]

Running 275/30/19 PSS on 19X9.5 ET45. PSS 10’s lowered to 25.75 FTG (a little less than a finger gap) , front fenders rolled and conservative alignment -1.4% camber all around . No rubbing at all, ran with 5M spacer and got slight rubbing LH rear on hard cornering/bumps with people in the back seat. At 25.5 FTG still no rub but too low for NE roads

[projectwoopass]

hmm. I see quiet a few people are running 275/30/19. Did you guys notice any difference in the road feel and handling? I know a 35 tire would fill the gap a bit more and absorb a bit more of the road noise and vibrations, but the adverse affect would be not being able to go as low with the car and possibly a bit more rubbing. Thanks agin everyone for the input and information about your specifications. This is incredibly helpful!!!! [:D]

I know that you have a S4, but I run 275/30-19's on my S5. ET is different but the car will hold them with no other MODS. No rubbing and I am lowered with H&R Sports. Not sure if that was helpful?
