Getting cold enough to soon put some all season tires on my 2017 2SS convertible. The new Michelin all season 4 comes in 255/35/20 for the front and either 285 or 295/30/20 for the rear. Will those sizes work for the stock wheels?

Yes, you'll be fine. The only snag is the speedo will be off by +2 mph at 60, because these tires are shorter—that is, at 58 the car will think you're already doing 60.

Choose 285 for the rear, 295 may be a bit of a stretch (I couldn't resist, because it's dad joke day in our house). Oh, and one more cringeworthy comment while I'm at it, this is an excellent way to shave a tenth or two off your 0-60 time . The speedo error would be smaller (+1.3 mph) with 295s, by the way.
