That size is available at Discount Tire - who own Tire Rack. I’m going to order them at my local Discount Tire before it gets cold here. I wonder if a call/email to Tire Rack would enable you to order them.

 

New member here. I just got a 2023 convertible with the touring package, which included the 21" rims. I have also been scouting alternative all season tire options for the car, as I live in the northeast and like to extend my driving season into the late fall and early spring. Never drive in snow, and only in rain when unexpectedly caught in it. I am now more of a Grand Touring driver, and I am not as concerned about max performance spirited driving as I used to be in my younger days. Stock UHP summer tires start to turn into hockey pucks when it gets much below 50 degrees. They become really slippery in the 40's and all out dangerous at lower temps, so all seasons are best option, since I don't want to swap wheels/tires.

I find it amusing that Lexus includes the "winter package" (seat/neck/steering wheel heaters and wiper blade deicers) in the touring package, has a "Snow mode drive selection" and then includes 21" wheels and UHP Run flat summer tires on the car that cannot be driven in colder temps. Isn't that the whole purpose of having a winter package ? Would not be so bad if there were a selection of alternate OEM approved Run flat all season tires as an option. Just saying...

Unless someone can suggest a better option in 21" tires, it seems the only option (as mentioned by other members here) for non-high performance motivated drivers is the Michelin A/S 4 in upsized front 255/40/21's with the 275/35/21's in the back. Although the Michelin Primacy tour A/S does come in exact replacement 21" sizes, it probably does not show up as an option on Tire Rack or other sites because it has a lower speed rating than Lexus advises. Because of the weight and power of this car, maybe not the best choice. To get into all season's it seems I will have to give up Run flat option (which many people don't view as a negative), create an emergency trunk kit with an air pump, slime, plug kit and maybe a jack, plus have roadside assist coverage in a pinch. I have driven a Porsche for years that came with a factory pump and slime kit, no spare or run flat tires, so kind of used to taking that kind of puncture risk.

Open to hearing other options, as I have not found any yet.

 

I have been Miraculously lucky with puncture placement and tire dealer plugging.
You can bet your a** if I had to plug a LC tire on the roadside that hole would be in the Hardest to get to spot.
Plugged a front wheel of a loaded 600 lb motorcycle on the side of the road in Birmingham. I was younger then and it was no fun.

Thus, the reason to add a jack to the emergency kit. If it’s possible to pull over to a safe place, can pull the wheel off and do a quick plug if absolutely had to do it that way (like if I was to get a flat in an area with no cell service, or can’t connect to roadside assist). Otherwise, the slime, pump option. Have to have as many options as possible when you don’t have a spare tire. Of course if a pothole takes out the sidewall, you are screwed, and only roadside assist is an option.

 

Assuming a upsized front tire (255/40/21), the other option that shows up for me are the Vredestein Quatrac Pro+. TireRack doesn't show me the Michelin A/S 4 even though it's clearly available in that size. As another member posted, I may have to call them up directly to order since the website won't show it for some reason. Not sure if it's a website glitch, manufacturer specific tires, or some other issue.

I've always run Michelin's, except for the one time I tried Continentals on my IS300, but am intrigued by the Verdestein's. The prior iteration of the Quatrac Pro+ was rated well and the three peak mountain rating is a plus given my planned usage for them. Decisions decisions....

 

The LC has very specific Jack points.
I sure don't want to have to try and find them on my back in the dark.

They are the same as any other car, behind the front wheel and in front of the rear wheel behind the side skirts (there is a metal plate/rail). They are even marked with a friendly arrow.

 

I've never seen Jack points as engineered as these. Pic is of front driver side (I have front end on jackstands awaiting dealer Michelin P5S tire replacement/install).

 

Your choice of the Michelin PSAS4 is a solid one for all around use BTW, 2023 was the last year for the RFTs on the LC. MY2024 comes with conventional Max Performance Summer tires, not UHP, as you posted.

Oops, it looks like I may have misspoken regarding the performance level of the new stock summer tires, but they still are warm climate tires, so the limitations I mentioned would still be an issue for cold weather driving tho. Just curious on your new 2024 setup. Since Lexus is installing non-run flats, do they provide an emergency inflation pump and sealer now?

 

Yep they sure do

 

Interesting 🧐. That actually makes me feel a bit better about moving to conventional non-run flats with an emergency kit. Now they normalized it. If it’s good enough for the Lexus engineers, that works for me.

 

so i'd like + size tires to replace stock dunlops to fill out the fender a bit better and maybe slightly improve ride quality. could be run flat or not.

so i think that's 255/40-21 and 285/35-21.

what are my options?

 

The option I went with is Michelin Pilot Sport 4S HL255/40R21 and HL285/35R21 tires.

The OEM Michelin Pilot Sport S5 tires have tread widths of 7.5in front and 8.7in rear, compared to 8.6in front and 10.2in rear for the 4S tires. A noticeable improvement visually.

 

Just checking in. I'm in Boston and my Bespoke is due in next week. Not great timing for the stock summer tires. Ordered all of the winter options as well.
Like you, I've found no AS or Winter tire options (at any price or speed rating) in OEM sizes except the Michelin Primacy. (What was Lexus thinking?) Is that what you went with? Does anyone know if any other oem option exists?
