20” wheel upgrade
2024 EV9 Wind on 19” wheels. As you all know, there are no all-weather tire options in the OE size due to inadequate load rating. I ran Michelin X-Ice SUVs for two winters which got absolutely decimated due to warm and dry winter conditions and dealing with storage and swaps is a hassle. So with OE abhorrent Kumhos at 3/32”, I decided to upgrade to 20” wheels and mount CrossClimate 2s which have the needed XL load rating in 275/50R20. The wheels are MSW Type 44 with gloss grey accents, 20x8.5. The new wheel/tire combo is 2 lb lighter per corner (68.7 lb vs. OE 70.8 lb), probably because it's not filled with that useless foam liner. Offset is pretty wide, outside of the tires in line with fenders or maybe even 1/8” wider but looks good. EV9 has fairly large front and rear brake discs (sorry, ID4 mafia!) so they fill out the open wheels pretty well. No meaningful difference in noise or ride quality on the test drive. Will report on efficiency in a bit.
Edit: Swap itself is very easy compared to the German cars I used to own. Only 94 lb-ft lug nut torque so don't even really need a breaker bar and studs instead of bolts are lovely. I used an aluminum pinch weld adapter from Potauto (Amazon) with a floor jack. Would not use rubber pucks - I think they are all of iffy quality and many reviews say they crack on heavy cars. Also note the front wheels are not locked when parked so don't forget to block them when lifting the rear.
