Bought with intention to use on 18" BBS alloy wheels (replaced with SR5 Tundra). Before installing these grommets, I threaded them onto the studs to ensure the thread pitch matched the OEM Acorn grommets previously used. Unfortunately, the thread pitch tolerance is not as tight/smooth as Toyota original lug nuts and they have poor thread engagement. I didn't turn on the dial indicator to see the deflection/play but I would guess it was 1mm - 1.5mm. If I were to use them, tightening them to factory specs would put undue stress on the threads as the hub's threads wouldn't make intimate contact with the bolt's threads. I will not use them and buy OEM tips.
