What information is there on the range differences with 18“ aero wheels with performance tires v
19” wheels with all season tires ( brands of course unknown )? Recall seeing a reference to some European configerators providing this generally but not the specifics .

In general you'll take a bit of a hit going from 18s to 19s. I suppose without knowing the tires themselves and their impact on range, it's impossible to give any specifics. I really want maximum range, but I just didn't like the look of the 18" wheels. So I went with 19" AS and am hoping for the best. I knew if I got the 18s the look would always bother me and wasn't worth the small difference (hopefully) in range.

I saw an interesting calculated analysis with formulas by an physicist geek for electric cars concluding that wheel size is a bigger factor than tire width or rolling resistance, with width the smallest factor. There is a specific calculation out there somewhere done on I think Tesla and VW with numbers for those cars on wheel size.

the EU configurator shows exactly the change in range by going different wheel options, nowdays is mandatory. going 18" --> 19" depending on the type of rims reduces range by 2-10km; changing tyre type to all-season might impact another 5km or so? so probably 7-17km range penalty

Thanks. If the EU configurator is in English can you send the link. Puzzled wouldn’t changing from performance tires to all season improve range ?
