crank hub doubles as a harmonic balancer.

Harmonic balancer or vibration damper?

Thank you, yep for installation. Found a nice YouTube short demonstrating install for anyone interested

I remember seeing the procedure done somewhere. Turns out it was Sreten's video of the valve seal on an X5 - skip to 24min

Yall think this is an issue… missing bits on the crank hub.

the orange is where the rubberized coating has come off.

crank hub doubles as a harmonic balancer. I would start looking to get that replaced.

Yes, my guess is they cover the valve keeper locking portion of the valve stem, so the seal can slide over without getting caught or damaged.

Anyone know what the red tubes are used for that come with the valve stem seal kit...I'm guessing they're used for installation?

What would be the going price for a solid 8.5/10 Mtextur interior (F2AT)?

3-5k depending on location

Holy $$ tires have gone up...

If you can buy in advance, wait for the DTD yearly sale.

I was curious and did some investigation about load ratings

https://www.tirerack.com/upgrade-garage/what-is-load-index?gclid=Cj0KCQiAvP-6BhDyARIsAJ3uv7Y6nx6UCU2AlODqoMjF-9lhTivJjhsIFQZOIC9GmqX8tW-Uu_cT5tcaAsOFEALw_wcB&ef_id=Cj0KCQiAvP-6BhDyARIsAJ3uv7Y6nx6UCU2AlODqoMjF-9lhTivJjhsIFQZOIC9GmqX8tW-Uu_cT5tcaAsOFEALw_wcB:G:s&s_kwcid=AL!3756!3!354820 920365!e!!g!!tire%20load%20index&gclsrc=aw.ds&gad_ source=1

Load rating of 89 is 1279 lbs per tire and 93 is 1433 lbs per tire

These cars weigh like 3400 lbs with about 50/50 weight distribution, so front and rear is handling about 1700lbs. I think those load ratings are more than enough. I don't think you need a load rating of 100.

Someone correct me if I'm wrong.

Awesome - thank you for this breakdown. This is exactly what I needed. I’ll take this feedback back to the rep I was working with and have them regenerate the quote.

I got the initial spec I referenced (235/265) from that tire thread.

I just checked that thread. For 265 width on a 19"
wheel, the recommended size is 265/30/19. You were asking about 265/35/19. Different sidewall height, different overall diameter. This is why I said we need the full sizes, not just the widths!

Did the rep say what the load rating needed to be and why?

As elrichmeister pointed out 265/35/19 is a stock E9x M3 rear tire size (I thought it looked familiar!). There's another option for the E9x rear, 265/40/18, in which the PS4S has a load rating of 101Y XL. Really grasping at straws here, but maybe that's why your tire guy thought 98Y XL wasn't enough – i.e. he looked up the wrong M3 and then saw the load rating on the wrong size? IDK...

That’s a fair point - they have my car in the system by VIN so he pulled my car up in their system and began his workflow.

Thank you for your feedback and help!

Americas tire does not carry a 265/35/19 Michelin pilot sport 4S with a load index high enough for my car according to the rep who quoted me today.

I got the initial spec I referenced (235/265) from that tire thread.

the thread lays out the tire size but I’m struggling to find the load index the front and rear need at a minimum to operate safely.

I’m seeing 89 for the front and 93 for the rear. I was quoted a tire that is 100 and it’s crazy expensive.

There is sticky thread on tire sizes

https://nam3forum.com/forums/forum/main-forum/e46-2001-2006/596-e46-m3-tire-sizing-thread

I made the same mistake, i just replaced my rears. I was running 245/35/19 and 265/35/19 which is not the correct sizing for e46 M3. Its actually OE size for E90
I didnt have major issues running this tire, i did rub on big bumps, and had some initial issues with my Flat tire monitor going off sometimes. Just wanted fatter tire lol.

I recently just replaced my rears with 255/35/19.

Bases on the Sticky thread you want
For 19s
OE: 225/40/19 255/35/19
or
235/35/19 265/30/19
or
245/35/19 275/30/19
