The newbie to summer tires is back with a related question.

Yup, not TPMS, my bad.

On the other hand, traction control icon would keep flashing on my old 5-series (no actual TPMS, direct or indirect) whenever all 4 tires were underinflated. I'm guessing it was somehow measuring that the rotational circumference was less than expected.

That's possible. If the diameter/circumference is less than it should be, it means the wheels have to spin faster, which it could interpret as slipping :unsure:
 
Really? So a flat tire has the same exact diameter as a fully inflated one?
Good grief... You're TPMS is only concerned that the operating pressure of all four tires is within a certain window. When you downsize the diameter of the tire by going to a smaller size, as proposed in this thread, it will not matter to the TPMS.

This isn't about a tire being flat. Don't be obtuse.

We're not talking about TPMS anymore.
 
You have to go to his other tread to figure it out, but "the car" is a Audi Q8RS.

Neither the traction control or the TPMS are going to give a flip as long as it has 4 tires the same size with roughly the same tread.
 
Winter tires in ATL? Completely unnecessary. Get some UHP all seasons. 285 vs. 295? No issue at all. Your summers don't implode below 40...below freezing yeah not ideal but 20 deg would be the "glass point" of most summer compound tires. Main issue in cold temps is cold and wet...dry is typically fine in the cold temps. I run summers here in VA through Nov then UHP all seasons as my "winter tires". Arguably the UHP AS vs. summer difference w/r to performance is slight....and if this is an SUV you aren't pushing dry grip slip angles enough to matter. My neighbor had the same issue...BMW X5M...needed all seasons for our winters here in central VA. Downsized a little and went Conti DWS06+ for year around/no fuss use. If you can't rip the Tail of The Dragon on a top-rated UHP all season you have a driver issue not a tire issue. There are TPMS or ESC issues. DT should have no issue mounting these. Summer performance tires would not be my choice on any SUV limiting it's use.

There are no all-season tires available in the OP's OE tire size 295/35-23 :sneaky:

However, there are more all-season options in a downsize 21" option with the size 285/45-21, such as the Vredestein Quatrac Pro+
 
the 285 seem to all have a load of 2149, where the 295 is 2205.

According to tire rack those pirellis are a little over 4700 a set... (yikes). Maybe he could just buy one of those mythical 4000.00 civics for winter....

I think we scared him off...

Its 20 in Atlanta this morning.
 
I'm becoming more of an expert every day 😀 and thanks everyone for the replies. I did pull the trigger on some cheaper all season 285's just to get me through the next two months then I plan to do a proper performance summer on the 23s and wil have time to find a good set of all seasons on 22 s for next winter.

Yes the load factor on the 285's is a 107 versus 108 on the Oem. Maybe I'm ignorant but I can't imagine that 50 pounds per tire max load is going to make a huge difference? I'll be sure to update when I'm actually done with this process. Yes remind me not to buy 295/35/23's in the dead of winter. Finding tires has been much more difficult than it should be.

You are fine on the load...both are XL and 50 lbs is not worth the discussion...but BITOG so some will say you will die 🤣. Yes big wheels have a downside as you are finding out. Good move to just get some 22s for a set of all seasons.
