Costco sells 3 "OEM" tires for Bolt. I can't see a difference other than tread depth on 33539. The only one in stock is 16798. Allegedly, only 33539 is self sealing, which is out of stock, but site doesn't mention SS. If that's true, why are the others listed as OEM if they were not sold on Bolt?

There are four versions of Michelin Energy Saver A/S in 215/50/17:

Non-SelfSeal:

90V
91H, TPC spec ?????? for Chevrolet Volt
91H, DT

SelfSeal:

91H, DT, TPC spec 3107MS for Chevrolet Bolt EV <- this is the OEM tire, and has SelfSeal printed on the tire sidewall

On Energy™ Saver A/S , if you look up the Chevrolet Bolt EV, you will see all three 91H versions as possible tires. The OE one has part number 33539 (which is not printed on the tire sidewall). The others have part numbers 11674 and 16798.

The 90V version has a lower load rating (90) and higher speed rating (V). The 90 load rating means that it is not recommended for a car that came with 91 load rating tires.

Thanks, that's good information. in my opinion, all the websites for manufacturer and retailer need to be redone since entering vehicle info doesnt return the stock tire the Bolt came with from the factory WITH self sealing. All the websites default to the ones with NO self sealing.

Super dumb site - doesn't tell you which one is self sealing. Not even clicking 33539 reveals anything.
