That's probably the gyroscopic effect. The more massive the wheel is, the more it wants to keep going straight on. So the rim deforms the tire and the rim plus the tire and even the hub and the spokes resist cornering. About the issue of mass on frame vs mass on wheels (most often on the rims) I found this article [1] where an engineer from Lotus states that "In the case of a wheel, because you have a lot of mass distributed around the rim, some distance from the centre of the wheel, that gives it inertia. [...] We can see that reducing the wheel inertia has a beneficial effect over reducing non-rotating mass, but it is very small. In reality, mass saved from the rims of wheels is likely to be less than 10% more beneficial than the same mass saved from the rest of the bike."
