Of course. My point being they aren’t $1000 more each or it would be loaded into the price.
New/retail/quantity of 1 I’m seeing 18” rims at $405, 19” at $380 (yes $25 cheaper), and 20” at $639 each. If you buy them from a Volvo dealer, Customer Care will send a rebate form.
Stock 18s are $202, 19s are $283 and stock 20s are $271 (shopping same source obvi can vary)
18 → 19 :: (-100)+(324) = $224 more cost in rims and tires at retail
18 → 20 :: (936)+(276) = $1212 more cost in tires and rims at retail
Assume whatever rims tires you get need tpms sensors, mount/balance. Only difference is parts cost.
While I’ve got my calculator out: if one of rims and tires costs $910, and I was hypothetically offered tire and wheel in the box for $500, I’d take it. If T&W was $1500 I’d roll the dice.
