I’ve used Tsportline 19” wheels with winter tires on my previous Model S. Quality of wheel is good and I did not notice any changes to energy usage compared to 19” Slipstreams. If you’re going from 21” wheels to 19” wheels like the Tsportlines, it is definitely a more comfortable ride since the tires are taller and absorbs more bumps.
I’ve bought 6 sets of this style of Tsportlines wheels for my Model S, X and now 3 in the last 3 years, so I think they are a good quality wheel and good price for what you get.
If you are planning to get a set soon you can use my referral code for $50 off a $500 purchase. TSportline does have good sales around Black Friday, so if you can wait a bit you might save some money.
Here’s my code below and I posted some pics of my X and previous S with TSportlines.
