So I took apart the trunk space in my 350 to see about putting the spare tire in there. It was fairly easy to remove all of the storage bins.

For reference, here is a Canadian NX 250 video on Youtube that briefly shows the spare tire.

Looking at the spare wheel carrier parts diagram, it looks like you will need all 3 parts listed in the diagram.

My only concern is that currently I do not see a hole where you would screw in the blue screw cap you see in the video. Looking at the parts diagram, there is a separate metal mounting piece that looks screwed/welded into the trunk where you would insert the blue screw cap into. I do not see this in my 350. In picture 3, the cutout in the foam cushion material seems specifically for this part. It looks like the Canadian 250 doesn't even have that foam cushion piece now that I re-watch the video. Looking in picture 4, you can see the divots where you would screw in this extra metal piece for the blue screw cap to go into.

I'm thinking the cushion part will do enough to keep the spare tire generally in place, but there is certainly potential for the tire to move around in the back and cause noise when making turns or going over bumps.

 

I also found this on dealer website and I am wondering what it is https://parts.lexusfremont.com/a/Lex...7420-5104.html

 

Those are the spare tire storage parts that I linked above. The cushion fills in the gap of the trunk space and has a circular cutout for the tire to rest in. I ordered all 3 parts today because Lexus has a parts sale right now, but my dealer advised me that the parts have to be special ordered and are currently back ordered, so no ETA yet.

 

Got the Modern Spare and put it in the trunk today. Removing the storage bins was pretty easy. The hardest part is removing the 5 clips that secure the seat backs to the top two bins, but just some wiggling back and forth with some force will get them out. They fly off, so try to do it slowly. The spare tire cushion (64777F6010) fits perfectly and keeps the tire in place. I will have to do a test drive later and see if there's any movement or rattling. This installation was so easy, which makes it even more upsetting that it wasn't included in the first place.

edit: drove around town and no noises or rattling of the spare tire.

 

This is great info, thank you for sharing!!

 

So somewhere around $270 to buy the spare tire and mounting bins, then you still need the jack and tire iron.

just looked, another $300 for the jack assembly!!!

 

That's a very good point that I have overlooked. Can't change a tire without a jack. Regarding run flats, it's my understanding if you get a "flat" and drive on it to get to service or home, the tire usually has to be replaced. So if this happens to not be withing driving distance to where they have a run flat in your size in stock, you've got a problem.

 

I am probably going to pull the trigger on this. I do see good scissor jacks on Amazon in the $60 range. Both run flats or a donut spare will be a nightmare if you have to use them on a long distance trip.

 

Would it be possible to get a parts list of everything needed?

I bought the full kit without the carrying case. They sent me the carrying case anyway. I think this is the best value as opposed to buying all of the OEM parts.

I would only get the spare tire cushion (64777F6010) and the Modern Spare full kit. The other two parts in the spare wheel carrier are unnecessary.

 

Thanks!! I saw where you, or someone said they'd bought just the pad. But after looking at the parts diagram I thought I was missing something. Thanks again!!

 

Would this work on the 350H or would the batteries be in the way. What if you have the ML installed would this also take up room? Thanks in advance.

 

Won't work with the 350 because of the battery. As for the ML, is it the subwoofer that could be a potential problem? I'm curious to see how much room it takes up.

 

The 350 12v battery isn't in the back. Maybe the 350H is?

 

With everything placed as in the left picture does the lid close as in the right?
