The most interesting measurements here are the size and tread width, which confirm that the Michelin Cup TLR isn't made for wide rims. Although the tread is slightly wider (+ 1 mm) on the 28 mm version, the total tread cover is even lower as (obviously) the casing of the 28 mm version is wider than the 25 mm version. The 28 mm version of the Michelin Power Cup TLR is now the tire with the lowest tread cover (35%) of all road bike tires tested to date, with most of the competition offering at least 40% tread cover.
You don't have to worry about running out of grip when leaning into corners, as our edge grip test indicates plenty of grip at high lean angles. The problem with the small tread is a higher chance of damaging the sidewalls when going through corners, as there will be situations where the sidewalls will be in contact with the road (low pressures, high lean angles, wide rims).
Just like the 25 mm version of the Power Cup TLR, we don't recommend the 28 mm version for wide rims. If you're still running 15 or 17 mm rims, these will probably be fine and offer incredible performance.
