What size are the Michelin X-Ice tires? They should have a very similar diameter/circumference to the OEM all seasons you got. You would need rims with similar offset and TPMS sensors. Frankly while some people use steel rims, I would go with winter alloy rims. DAL makes some. Try 1010Tire and PMC Tire as they are in Canada.

23+ RX uses different wheel bolts than the lug nuts on all older Toyotas. This means you need new rims.

These tires were mounted on my 22/RX with the OEM lug nuts, the diameter of the tires haven't changed between 22 & 24 model years. The tires are mounted on alloy rims and have the Lexus temps installed. To simplify my question what size lug bolts would i need to mount the alloy wheels to convert from 22 model year to present. As I understand the 22 had flat surface lug nuts and the 24 has tapered lug bolts. I'm looking for lug bolts that would fit my current wheels for mounting.

I have not been able to find any lug bolts with flat washers. I also asked few Lexus dealers and they all said they do not have any conversion lug bolts to use the old Lexus wheels on new Lexus vehicles

If someone finds them please post the info.

I believe TPMS in 2023+ RX is different that prior years.

On the positive side I was able to use the Center caps off the old RX on new RX winter wheels.

I put way too much effort to try and find that M14 bolt with a flat seat. No go. I sold my previous setup from my 3RX 450h to a friend and just bought new from PMCtire.com. I am awaiting shipment now. It is coming with conical seat and bolts and will be my dedicated winter setup, and the default spherical will stay as my summer setup.

Live & learn, I only have 4,000 km on my winter setup. I'll keep the x-ice 18" tires, they work well for Canadian winters, sell and replace the alloy rims and TPMS. Thanks for all the replies.

The only thing to keep in mind is if you have 500H or 350 F sport, you have those massive 6 piston brakes. Which only fit the larger rims due to the calipers size. Smaller rims will not clear the caliper.

toyotaman7

BTW, are you sure 18" fits the non F sport RX5s?

The dealer told me 19" for my RX350h as the minimum, I am not sure though.

RebornRX

The difference is minimal, a 21" winter tire is plain silly. No benefit in a 19" setup. You'll have limited options, and put a hole in your pocket.

toyotaman7

I don't mean the tire revolutions, I mean does an 18" wheel fit on this car? The brakes might be a bit bigger than the 2022 RX.

RebornRX

I went to a reputable tire shop that sold my 18” winter package last year. He had 18” & 19” rims to fit my 350h. I priced out the 18’s to be mounted on my current tires with new TPMS. I will get these done in the next week or so.

Please keep us posted once you install them on the car. Thx

I put my on yesterday. 18 inch rims have plenty of clearance on my 350h. Tires i bought were Continental - VikingContact 7 - 235/65R18, therefore no change to the speedometer.

toyotaman7

Thx for letting us know.

RebornRX

What about rim offset, I think our 350h has a 40 offset, while the previous generation is 30.
