All,

I am switching to a wider rear tire so I figured I would offer these. They are still currently on my car and have ~4k miles on them.

The tread remaining is right close to 6/32". New was at 10/32"
(2) Michelin Pilot Super Sports 285/35R18
Specs:

Bought New in Mar'13 with my current wheels.

New these go for $300 each ($600 plus shipping) from TireRack.com.

I will let these go for $320 shipped to Cont' US.

Possibly interested. Can you post some pictures of the tread and sidewalls on both tires? Current tread depth measurement? What kind of use have they had (street, drag, road course, grocery store, etc.)? Is the 4k miles from a year and a half ago, or is that current?

If any of you gets a chance could you possibly shoot a pic of the sidewall with a measuring tape or give me some approximate measurements of the sidewall height please, i'm really curious about the sidewall height on this size tire.

much appreciated!

According to TireRack, the diameter of a 285/35ZR18 Michelin Pilot Super Sport tire is 25.9" when measured on a reference 10" wide wheel. 25.9" - 18" (wheel diameter) = 7.9", which you would then divide by 2 to get one sidewall measurement (from wheel rim to top of tread), which is 3.95 inches.

Actually, the more precise way to measure sidewall is as follows: 285 mm (tire width in mm) x 35% (aspect ratio) = 99.75 mm divided by 25.4 (to convert to inches) = 3.92 inches. Not much different result but, with wheel/tire/fender/suspension interfaces closer than ever on many cars, even hundredths of an inch can matter.

^ Ken, I agree that your formula should be accurate, but I'm not sure that the 35% is always exactly precise for all nnn/35/R18 tires. It's easy to find 2 different 285/35ZR18 tires on TireRack that have different total diameters. They won't both be 3.92 inches (nor 3.95 inches). The diameter formula I listed should be more precise for each individual model of tire. Admittedly, we're talking about splittling hairs here.

Both are estimates - I assume the 35 profile means it is probably between 34.5% and 35.5%. Looking up the actual number is best when available.

Of course, then you have to factor in tire pressure, et al, blah, blah, blah...! ;)

Makes sense and points well taken. Thanks for the different perspective as the methodology you recommended is not something I had previously considered.
