I'm a bit sceptical as to whether these will work on the 19" OEM 370 rims.
Unlike the 350 Rays/Nismos that have a pronounced lip to help the protectors 'grip' the 370 wheels are flat faced which suggests to me the tyres would have to be removed to get a large enough area for them to 'grip'?
You can see from the rim design, when used with tyres that have rim protectors as in the pic above, they already offer a little protection. Yes, I have seen kerb damaged 370 rims but in my experience the 370 rims are a little less prone than the 350 ones.
Yeah, I have maybe been lucky so far not to have any kerb damage in the 2 years I have had the 370, but when parking I always make a point of coming in at reasonably acute angle first so that the rear tyre hits the kerb which, with the mirror I have angled to see the rear wheel area, helps to find the distance from the kerb and then a forward shunt putting the lock hard on so again the front tyre hits the kerb lets me know I am close enough in before straightening the car. Not easy when spaces are tight -I agree, but has worked so far
