I recently purchased a 2020 GX Premium...love the vehicle, but I’m not wild about the dark 18” OEM rims. I’ve checked with a few dealers to see if they could provide a part number/price for the polished 19” OEM rims from the GX Luxury model. So far, no help from the dealers......any ideas? I would truly consider purchasing a set if I can get a somewhat reasonable price.....

They are pretty new, so your chance is to get them directly from dealerships. Try online Lexus dealer, they might have some in stock. Check local craigslist you might be surprised what you can find there.

Also check the tire selection, there are very few options for that size right now on the market. Good luck.

... yes, 19" tire options are somewhat limited ... so unless you really want 19" of bling, I personally would not go there.

Also, unless you are absolute on OEM rims ... IMHO the spend is better applied to rims that are wider than the anemic 7.5" standard Lexus/Toyota issue. Also the OEM offset is way too inboard ... pushing outboard gives the vehicle a more planted stance.

One item to consider with non OEM wheels (or spacers) is the offset effect on the wheel bearing performance and reduced durability/reliability... (the F-Sport wheels are 18 x 7.5 with 20mm offset as an example)... going more deep dish (to push out the tires) creates more stress on the wheel bearings (this is simple mechanics) and also if larger than non oem overall diameter tire is used, could lead to interference issues when turning with the fender liners and body mounts...

if the OP wants 19" oem wheels, I say go for it with the understanding that the tire options are very limited in this size.

ASE

The GX460 wheel bearings are not the same part number as used on a Prius ... so can easily handle wider wheels with additional negative offset. The GX460 is a truck based platform ... not a delicate flower that will implode with any change in wheel width or tire size. As long as any change is reasonable, the wheel bearings have sufficient margin to accommodate.

I don't know the numbers for certain but if you do, please share, we'd all love to see them to support the assumption/claim it can easily handle it.
Being a mechanical engineer, you are correct in some respects... Every design is run thru FEA modeling however this is generally only done for the OEM product specs (within the tolerance of manufacturing)... no manufacturer is going to perform FEA for aftermarket iterations.. what they do is look at the forces on the OEM component and may select or spec out a part to be manufactured that exceeds these modeled forces by 10-30% margin depending on the function of safety or non-safety critical.

All this to say you are right, there is some margin in any design but to be able to calculate the difference on the reliability or durability of the wheel bearing is not possible. It could fail sooner since the accelerated lifecycle testing hasn't been performed or simulated for the changes in geometry in loading and steering

ASE

... better perform a FMEA before changing the gear shift **** because the engine might blow up

So lets go real world and count the number of posts on 4-Runner / Tacoma / FJ Cruiser / GX470 / GX460 Forums where wheel bearings have failed (at any mileage) when the wheels or tires did not exactly match OEM specs.

Ok, a quick search for posts yields the following... it happens.

Many of these posts concluded that the noise was from the tires and not bad wheel bearings as they originally suspected. Also, if any wheel takes a violent hit ... off-roading or smacking a curb ... yes the wheel bearing can be compromised as would be the case on any vehicle.

My point back to your response ... you want data, well then YOU should not invoke fear with your original post unless YOU have data.

To your "interference and rubbing" concern ... there is much information available on what rim size(s) / offset(s) and tire size(s) will fit an un-lifted GX460 without rubbing ... so absolutely no fear justified here unless one does not do their research.

I have a 2017 GX Luxury and had considered the same.

I'm not trying to invoke fear... just trying to give the OP a different perspective... in the end, he/she wants OEM wheels so there is no issue and his/her warranty will be fine.

If one rolls up to the dealer with aftermarket wheels and tires and has steering component issues or wheels bearing issues, very few dealers would make a warranty claim for that owner... there is some risk, however small, in modifying any vehicle with non OEM parts, that's all I'm trying to express. I'm done talking about it because we both have valid perspectives, neither of us is right or wrong, and no point going in circles.

Bell Lexus says PN for 2020 - 19" Luxury rim is ------> 42611-60E80

It’s funny you post this. I checked with Bell Lexus and they’re the ones that told me they couldn’t find a part number yet. Apparently you got the right person! Thanks....I’ll give them a call again.

Woodyboy

Not sure what price they have but here's a link to the best price I've found thus far $389.98.

I live in suburbs of Charlotte, so I might have to take a road trip down to pick up a set of these. I really like the look of them. My only concern is the lack of decent tire options available for now. I hope as time goes on, more tire makers will offer some additional alternatives. Thanks for the info!
