I want to get some new or very lightly used (no imperfections, no damage, no curb rash) Michelin Pilot Super Sport tires.

I'm looking for the following:

F: 245/40/18
R: 265/35/18

I have a set of 4 (staggered) OEM Continental ContiSportContact 5Ps with break-in mileage only that I'm selling for $600

Zibby,
I just blew out a front tire and am going shopping for a replacement tomorrow. I'm planning on a 245 PSS and am debating between a 35 profile and a 40. What made you pick 40?

I am Jeff

He's going with 40 because that's the appropriate profile size for an 18" front tire. You should only be going 35 profile with a 19" front wheel. Your speedo is calibrated for those dimensions.

Just did the math. If increasing from a 235 width to a 245, a series 40 tire is about 0.3" taller and a pound heavier while a 35 series would be about 0.6" shorter and a pound lighter. Weight difference on the 245's is 2 pounds. It seems like a viable tradeoff between looks-better vs goes-faster.

Speedo calibration isn't an issue here - we're talking front tires. And speedo calibration is impacted by more than just profile, as width also has an impact. For example, replacing a 265/35/18 summer tire with a 235/40/18 winter tire would give almost exactly the same speedo calibration.

No offense but you know they sell these at places like Tirerack, Discount Tire Direct, etc?

You might try usedtirehouse.com. They seem to have a big inventory of used tires, show tread measurement and good photos to document what they're selling and they're somewhere in Ohio, possibly close enough to do a pickup.

I am Jeff

So you're starting at .6" shorter with full thread, that increases as you wear down your tires. The difference magnifies with wear. The added benefit with going with 40 profile tires is that the increase sidewalls more rim protection and increased ride comfort. I can't imagine anyone wanting to go with a lower profile without any added benefits such as larger wheel size.

Vice - those are the go-to places to check out NEW tires. Are you telling us that they also sell used tires??

His thread title states 'Lightly used or new'. If he is open to new tires he should just go order them from one of those sites.

Duh - speed-reading gets me into trouble again.
Thanks.

See the post I quoted below.

Yep.

None taken. I'm trying to sell my OEM Continental 5Ps right now and I have received fair offers but the shipping aspect is killing the deal. I love the 5Ps but want more/wider rubber on all four corners.

My first plan is to buy new but with how frequently people change out tires and wheels on here, I figure I would post this up, just in case.

Just my 2-cents....I wouldn't recommend the Michelling PSS! I have about 5k on the rears and they are just about ready for replacement in another 1K (if that). Absolutely no burnouts and no "spirited" driving. Just daily driving, mostly on the highway. These are warranted to 14K by Michellin (for our staggered fitment, 30K otherwise). I fully didn't expect to reach that but 6K? Common, I expected more around the 9-10K range with that 300 thread wear rating. Grip is good but only when they are fairly new. Once I put about 3K on them, I started feeling the back end slip around on tight turns. At 6K, forget it. Anything more than a feather-lite tap on the gas is spinning them, even on straight takeoff. The front ones are wearing a little less slow and hopefully will last another set of rears. I'm only getting PSS again because the fronts are still decent and Michellin's prorated warranty which will cut down the price of a new set of rears. Beyond that, I'm going back to the Hankook Ventus I had before. Same level of performance and wear for a lot less $$.

A member just posted a set for sale, worth checking out.

Link?
or if it's easier, forum name and topic of posting?

Thanks for sharing. I'll try to track down the listing.

Uh oh are we both going to be gunning for these lol?

Thanks for the writeup! Appreciate your thoughts.

It is not the tires, but the rear toe in. Mercedes specs a very aggressive rear toe in, and it eats tires.

I would suggest having the car realigned, and kicking out the rear toe.
