Wow, a MB tech should know better. Yes you might get better wear, but very likely to wear early in center of tire.

Best to dial in the pressure first thing in the morning (cold) before driving, given door pillar label and your preference of course.

Hey MB-SV,

That's what I thought too but please allow me to add this. The CPO car with 53,000 miles had a new set of Continental ContiProContacts mounted when I bought it almost exactly 24 months ago. I now have a little over 71,000 and the damn things were shot. I mildly complained to the parts guy (after 3 different techs told me the tires were badly worn) and these were what he recommended, at least partly because they would last longer. He also said he "got a good deal on them". They do have the 93H MB recommended load/speed.

I thought the Contis were excellent handling tires, but 18.000 miles? Sheesh, that's ridiculous! Not to mention that they charge $130 for the OEM Contis and these were $112 each.

MM - Good info. I too had mediocre tread life with Contis on a 01 MB C240 and 05 Jag X-type in the past.

I'll monitor the OEM Michelin 17" staggered tires on the 08 C300 Sport (has about 12K miles so far) and let you know if they should be recommended. So far, so good.

Thank you in advance MB-SV. I thought about Michelins, and being the way I am, would have preferred to stick with OEM tires. I'm not sure, but the new E-Class come with either Michelins or Contis. As an afterthought, I should have called MBUSA to see what tires were OEM for my car and bought whatever else they used other than Continentals. BTW, the spare is a Conti so I assume (bad idea I know) that those were the original tires.

I've been dong 60,000 on Michelins. I also made over 60k on General's on our ML320, but had to replace 2 of them earlier because of flat. If you like hard cornering, you better add couple of psi. I drive on min 30 psi in the rear and above 30 in front and still have sides wearing more than center.
Coming back to original question. Changing the tire profile generally should not change the tire inflation. If in doubt, you should contact tire manufacturer for advise. Usually they have pressure recommendation varied with the load, so you need to find the load on your tires.

A note of CAUTION here.
You are running 225's in a car rated for 195 or 205.
Do not be surprised if your Alignment is off.
Do not be surprised if your tires prematurely wear faster than
tire mfgr. rated them for.

From 15 inch to 18"? Wow.

Your alignment symmetry is way off.

I hope you have your car realigned.
Also your Speedometer, with the severe out of specs; is no longer accurate.

Just food for thought....

An extra 1.6 inches taller in diameter, great if you are trying to get more ground clearance for offroading.

And significantly slower acceleration, not a good setup at all.
