Most shops said they cannot do 22'' but I did find one can. It charges more but still cheaper than the dealer. It also claim that it can do kind of balance (faster spin?) that even the dealer cannot. They do say that they won't know if they can do alignment until they see the I-pace.Dude, this is a normal car!
it will need an alignment periodically. There is no special magic for mounting wheels or balancing them. if a reputable tire shop says they cant do it, find somewhere else because this is a huge red flag. mounting and balancing a tire on a rim is the same whether you are driving a 1962 lincoln, a lamborghini, a pagani or a jaguar i pace. it requires standard, ordinary equipment.
any reputable tire shop should be able to do the work for cheaper than the dealer. if you insist on having the dealer do it, be prepared to pay a bit more.
don't be worried, this is not complicated at all.
