I just got some new wheels and ever since putting them on my car is shifting strangely and cutting power . Theyve got great tread so im a bit confused what it could be. running 265/35/zr18 in the back then 245/40/zr18, fronts and backs are different brands so is that the culprit?

Due to the 30th anniversary set this card has almost quadrupled in price, would it be smart to sell now around 400, or do you think it has more room to grow?
