275/35/20 or 275/30/20 or 280/30/20 on 20x10 et30 wheels. Car is not lowered and I do not plan on doing that. I would very much like to maintain stock like ride and living in NYC, dodging every pebble on the road used to be a fun game when I was younger but not so much any more.

Any recommendations would be highly appreciated!

TIA

1. I assume you mean 285/30/20
2. What model car? A5, S5, or RS5?

Look at the postings on the wheel gallery thread. Tons of info there. Also the guys from Nemesis Autosport have given some really great fitment advice. I will be ordering a set of BC Forged wheels from them soon once I decide my final spec.

Oops!

B9 S5 SB and yes I was just reading up on that. Mops seems like a very helpful and knowledgeable dude for sure

Mops got me dialed in for my set-up. He knows his stuff and is incredibly easy to work with. He’s on the east coast and I’m out west. Not a problem. I went with 20x10’s with 285’s. Perfect set-up for me.

You mind sharing some photos? 285/30 right?

I believe his car is an RS5. not an S5. Honestly, unless you are going to tune these cars for big power, you don't need more than the 265 width that comes as one of the S5 options. You could go to 275 on a 9.5" wide wheel with like a 28-34mm offset if you like. But many people just add weight in both tires and wheels unnecessarily. This hurts your ride and steering response. Also, if you go too wide and don't actually lower the car, from certain angles it can actually give the optical illusion that your car is raised.

Yeah living in NYC with a lowered car is not something I see myself doing. I might consider air ride only because I’ll have the option to adjust height on the go but certainly not now. As long as I am not feeling the road much or dodging pebbles like they were landmines, without the optical illusion of driving a boat on land, I will be ok. Just not sure what the “right” size would be for that

Wheels are Blaque Diamond F20, 20x10 et30

i'm in NYC as well, on my B9.5 S5 i'm running 275/35/20 Vredestein Hypertracs on the stock 20" Black Optic wheels. i have no plans to lower it either, great size i'd recommend it, feels more comfy and "protected" and gives you peace of mind on bad roads. you can see my profile thread history i have the tire thread somewhere with more info and pics. or might be on another forum - https://www.audiworld.com/forums/aud.../#post25747296

So this a is huge increase in the rolling diameter of the tire over the stock 265/30 on the 20" S5 wheel. One can obviously do this, but it is way out of the range of what is recommended to do. Also note that it raises the overall height of the car my 17mm. On the other hand, it also lessens your visual fender gap by the same 17mm on a stock suspension. Whether one likes the overall look is an individual decision. It will certainly give a bigger air cushion for bad roads.

For the OP.......opinions and choices will be all over the place depending on what is important to you, and what your goals are. Some people really only care about appearance and not performance. Despite the fact that they bought a performance car, it is all about the "look" and the "image". That will lead you down a very different path than if you want a car that is best as a real daily driver. Different, still, will be if you actually want to maximize performance. I have been tuning and modifying cars for over 40 years and have seen it all. I have also seen people (myself included) go down the rabbit hole of doing a mod, which then needs another one, which then needs another one, etc. So....if you want to go to any kind of extreme, that is a choice you should make after fully understanding what you are getting into.

If not, and you have the 20x9" ET34 wheels on your S5 with 265/30 sized tires, and are keeping stock suspension height, I would do one of the following:

1.) 20x9.5 with a 30mm offset and stay with the stock 265/30 tire size
2.) 20x9.5 with a 34mm offset and go to 275/30 tires.
3.) 20x9 with a 26-28mm offset and stock 265/30 tires (this will give a slightly more flush look, not alter your scrub radius too much, but will be the lightest wheel option staying with 20" wheels)

One of these will give you a good overall balance between looks, performance and daily drivability. If your goals are different, then you can go down a different path.

The other option, if you are really concerned about bad roads is to downsize to a 19" wheel and go with 265/35/19. This would also save weight which is never a bad thing. Going with a smaller wheel and larger sidewall tire will also decrease your visual fender gap appearance. Finally, look at the weight of both the wheel and tire you are considering. No point in spending extra money to have boat anchors at the corners!!

This was an amazingly detailed explanation! Thank you so much!

Would it be terrible to run 19x8.5 and 19x9.5 et38? Found this really clean set of BBS LMR’s.

19x8.5 would be too tucked without spacers. 19x9.5 would work well I think and should clear all suspension components, but I don't have an S5 so I am guessing from what I have read online. Pair with a 265/35/19 tire.


Go Here:

The tire calculator will give you all the info you need, although the specific clearance of an individual car are up to you to figure out. Also don't put too much faith in the weight measurements of the wheels and tires as these can vary significantly. But in terms of dimensions, it will give you really good info.


Also look here:

This is my 2020 Spyder with stock suspension and stock sized wheels and tires. Look at the perceived wheel gap at the rear vs the front. The rear wheel/tire is much more flush to the fender so the perceived wheel gap is greater than the front which is tucked a bit. In actuality, the front fender gap is GREATER than the rear, but the relative position of the tire to the fender can create an optical illusion.
