So, apparently, they aren't the exact same. I was in the process of purchasing the 18in RTX Wheels for the Model 3 Performance and was warned by a few Wheel companies that stock them that there is a fitment issue as the Model 3 Performance has a step-up center bore from 64.1mm to 70.1mm for 2.25mm, which means the 18in RTX wheels (with a center bore of 64.1mm and NO step up) will not fit. However, Tsportline guarantees fitment with the Model 3 Performance, and I spoke and confirmed with them that they have an adjustment for the step-up. However, the RTX wheels are an excellent option for the Model Y as it doesn't have a step-up issue.These are not T-sportline wheels however I am convinced they are exactly the same ones at 1/3 of the price. See post #31 on page 2 and other posts I made in this thread.
@TSportline, I'm not sure if there are any other differences, but from what both websites state, they're rated for the same loads, stylistically they look almost identical. But the step-up adjustment is quite important for OEM fitment from what I understand.
I'm happy to be proven wrong here and by no means am I an expert on wheels, just repeating what I've been educated on.
