I would bypass the desk workers and try to find out whom in the service dept actually worked on your car and get it directly from them what happened.

 

yes it did fit me and my brother both saw it in there

 

I know for a fact it was a 17 inch spare because i was gonna switch it out with the wheel on the front because it had a scratch so i checked to see if i had a full size spare and i did full 17in oem spare. Then after i got it back from the dealer i went to go change it out with the scratch wheel and it was gone. And what made them check there was they did a full service inspection on the inspection list it says they checked my spare tire

 

Have you tried sticking one of your other oem rims in your trunk to see if it fits? Everyone is saying it doesn't and I don't think it does either. Also I doubt a dealer would really need to "steal" your oem spare back...just doesn't add up.

 

Assuming you did have a full size......

Why didn't you take a photo, knowing your case was an exception to the rule.

If you cant convince a Lexus forum, then chances are you can't convince a dealership. If you value your time, save it.

Best case scenario, IF Lexus finds out from a tech that they did swap out to a donut, then the best they will do is acknowledge the fact that they actually did swap it out.

The car is designed to store a donut. Regardless of sketchy thief involved, Lexus would not want to be negligible for having the wrong size tire in trunk.

Next time you see something out of the ordinary, document it

 

If it was a full size spare, would you have had a tpms sensor in it? If it was "stolen" I'm assuming your sensors would be going off. In any case I doubt one can fit in there. Try it out and let us know.

 

^^ even if the full sized spare in the trunk had TPMS, the indicator light wouldn't go off because if they swapped out the full size with a donut, it too would also has TPMS correct?

And like thermometer (myself and many others) said, a full sized spare does not fit in the trunk in 2IS (that is, sit completely flush with the floor as well as with covers and carpet)

 

^^No tpms on spare tire on the IS.

 

^^ is that the new thing for 2011?

 

I think all will be resolved if a full size spare will fit in the trunk. If you try and it does not, then you know you are mistaken. Either way, you need to take this step. A used tire lot should have one around that you can try just to see...

 

The IS never had a 5th sensor, or full size spare.

 

So many of you guys have non-stock rims i'm suprised someone has yet to try and fit the stocker in the trunk to end this thread?! Where are all the nay-sayers when you need them?! I'd do it myself but I don't have an extra stock rim just lying around.

 

^ I would, but I have a fatty sound system sitting in my trunk. I don't think it'd fit anyways. The donut is very thin compared to the OEM wheels, and even if you remove the Styrofoam padding, the OEM wheel would still be too wide (tall, if it's sitting its back). Yes, you could technically make it fit, but that would involve having a raised floor; much more work than what it's worth. If no one else will test fit it, I might pull my subs out and do it myself when I get some free time

 

i'm 99% sure the 2011's have a 5th sensor for the spare.

 

Nope, and I know because I programmed them myself.
