Pretty much the title. I got new wheels with tires already on them and had them installed at a local tire shop. Afterwards I got an alignment and balance as well for good measure. However afterwards I noticed that going above 60 mph the steering wheel starts vibrating and the steering wheel is also slightly crooked to the left. This made no sense seeing that the wheels and tires are brand new and the car never shook at any speed before installing them.
2 of the tires are 235/35/R19’s and 2 of them are 235/40/R19’s. Upon further inspection, I noticed that the shop put both 235/40s on the left side and both 235/35’s on the right side. (Face palm). Is this for sure what’s causing the shaking at higher speeds issue? My apologies, I know nothing about tires
Another question: after I switch the wheels so they’re the same dimensions on each axle, do I need to rebalance and do a new alignment?
