hey guys

i just swapped the tires from summer to winter and i did the Replika R163A (Hyper Silver) with Toyo Observe G3 Ice. Got a pretty good deal on them brand new. Was going to get the Winter Contact SI but conti kept shipping the shop tires from 2014 so went the toyo route (toyos were slightly more expensive)

anyways i noticed coming home from the 275/40R20 and 315/35R20 when the car was braking that the rpm would shift from 1k to 1.2k when normally it would just slowly decrease ... is this normal? is this okay for the car?
