I saw a few posts here about 18” wheels that fit on the MYP and just wanted to record a datapoint that does work. I know a few folks here have them on their LR and I was concerned about clearance with the MYP rear caliper cover.
Specs:
RTX OE Spider 18x8.5”, ET35mm 64.1mm bore
Michelin Pilot Sport 4 All-Season 245/50ZR18 XL 104Y
Stock TPMS
Weights:
RTX Wheels: 21.8lbs ea (fish scale)
18” Tires: 29.2lbs ea (fish scale)
RTX wheel+tire: 51.4lbs ea (bathroom scale)
MYP 21” Uberturbines (F/R): 67.0/71.2lbs ea
Clearance:
I was worried about buying these sight unseen but went for it. Before mounting them, I dry fitted them to the car and found about 15mm clearance in the front and 10mm in the rear calipers. Basically one/two finger thickness gap. Seems right but plenty for how thin wheel weights are. I found Gemini wheels to have a pretty tight clearance as well.
Efficiency/Ride:
I haven’t driven on these more than a few miles but I plan on updating this post if people are interested. Since the tires are basically the same compound and weight as before, I don’t expect tons of efficiency gains.
Cost:
$1078 CAD/795USD shipped. Got these off eBay and they came to California in about 8 days. Brand new and decently packaged. Store was called partsterr_canada. No affiliation. Use a CC that doesn’t have foreign transaction fees.
Tires were ~$250ea from tire rack. This size is more affordable than 19-21, another benefit.
TPMS were $110/set also from ebay. They are takeoffs so they were fully functional but showed minor wear.
So far, very happy with the fitment, cost and ability to rotate. Time will tell on efficiency.
