Run flat tires

[icicles9]

I run 44 psi front 42psi rear
None run flats Michelin latitude sport 3
Quiet, more comfortable than the Bridgestone duller run flats
Toe, minimum
Staggered 20"
Very happy

My new Continentals Sport non-RF summers are pumped to 38 psi according to the sticker, as were the Bridgestones.

I usually used to pump tires to max pressure as per the tire sidewall as I like firmer ride. Then I started following the sticker + 5-10%. The Continentals side wall (as that of Bridgestones) say 51 psi.

Anyone tried driving non-RF at 50 psi? Downside?

My first impressions of non-RF Continentals Sport summer tires were too soft at 38 psi.... and too noisy compared to my high expectations.

Update
Went for alignment (and oil change) and apparently my tire rods are ceased and the front bushings are gone, which may explain tire wear as far as I read on this forum. Alignment delayed until the parts arrive. Oh, and the car started pulling to the right...parked until alignment to save those new front tires!

Oh and at least part of that noise is the driver side front bearing! Another 2gs plus))) I miss my Acura already!!!

I'm running 36psi all around and am pleased with the even wear on my Bridgestone Dueler HP tires. The tires are wearing evenly. The 315/20 run flats in the rear are looking really good after about 12K miles. I would think at a higher inflation it would stiffen the inner sidewall and exaggerate the wear? Without asking my tire installer filled the tires with nitrogen. I believe nitrogen results in less thermal variations than air.

What's the break down for parts and labor? 2k seems a bit much?

I dont recall the exact numbers and will provide as I get the confirmed quote, but something like that: Control arms with bushings about CAD 430 x2 sides, the tire rods about CAD 200 for both parts of tire rods x2 sides plus labiur for each at CAD 120 per hour, plus CAD 180 alignment, plus frint right bearing for CAD 600 inclusive labour. The quote is yet to be confirmed.

Are they putting in OE BMW parts or just no-name replacements?

OE:
https://parts.bmwofsouthatlanta.com/...126791395.html


OEM:
https://www.fcpeuro.com/products/bmw...er-31126791395

Aftermarket:
https://www.fcpeuro.com/products/bmw...-31126773949?a

As you can see, price goes from US$318 to $89, from OE to aftermarket....

If im running a shop I am installing the aftermarket parts, telling you there are OEM and charging 20% over OE MSRP prices.

Enjoy!

Thanks ard. I was told all OEM except the bearing which is OM and is apparently CAD 600 for the part only.

Waiting for Wednesday appointment - the bearing coming from West Coast.

Pumped up all wheels to 42 psi - so far on low speed it feels better - firmer with more feedback. The funny thing is that the front left was at 4 psi higher than all others after a bit of driving so didnt need to inflate that one. Now the car diesnt pull to the right as it did this morning. Same story as on my long trip. The front left must be overheating. Coincidentally, this is where the bearing will be replaced...

There are multiple OEM and aftermarket vendors for that bearing.

Man, they must LOVE you.

Thank you ard. Much appreciated. I will be making some calls tomorrow morning as they may be ripping me off.
