245s on the back of the 21s Possible?

[CWedge411]

I know the rear wheels are wider but could 245s fit for snow tires for the winter? I guess my real question comes down to Will the computer know and everything get mad?
Has anyone tried? Thinner tires are better in the snow, also cheaper and I only have a 18mon lease so i'm trying not to spend a ton on this car, till Gravity

That's quite a bit of stretch, especially on a 21" wheel. IMHO, you're better off getting a dedicated set of winter wheels and tires rather than mounting, dismounting and rebalancing tires every year.

Yes, "Hey Lucid" will curse you out while DDP drives the car back to the dealership!

But seriously, I agree with @terrycs. 20 mm is (quite literally) a bit of a stretch on 21's.

According to Tire Rack both the Michelin and Vredestein 245/45-21 snow tires are good for 7.5 to 9.0 inch wide rims so neither would work on the Lucid 9.5 inch wide rear rim.

Cool thanks for looking at that. I didn't even see that on the site.

Agreed but as i mentioned it's only a 18 month lease.. mounting and balancing twice wont equal the cost of a new set of even 19" wheels and TPMS sensors.

Good point for an 18 month lease. Maybe consider leaving it as is and go with cables, chains or socks if comes down to it? That would be cheaper than a pair of tires, no? Think of the increased blowout risk from stretched tires since the sidewalls would be even more susceptible to potholes.

Summer tires are only good to 45 degrees, It was 45 last night here in Boston. Basically summer tires turn to hard plastic like in the cold, essentially like those kids big wheels back in the day that slide around everywhere. I am not worried as much about the snow as just grip in the freezing cold. Non-Ice/Snow days. Most of my travel is highway, so I can't use chains or socks for that. I'll have to take a chance on Blowout (knocks on wood) Ive been doing ok, all my past cars have been either 21' or 22' wheels

Yes if you had all-seasons I'd recommend just driving. The recommended rim sizes can be found on Tire Rack by selecting the tire then selecting specifications.

when it comes to tires, car companies can be between a rock and a hard place. Ultraperformance summer tires makes perfect sense here in Scottsdale; not so in my former haunts in Boston where an all season tire would make more sense. Genesis put Michelin Primacy all season tires on my GV60 Performance and I have hated having them since day one and as of last week I bit the bullet and replaced them with Michelin Pilot Sport 4S HL rated tires. But these would not be great in December in Boston.

With an 18 month lease you have very few attractive options. The only thing I can think of is to check the Lucid Marketplace here and see if anyone is selling all season tires or winter tires and, if not, try posting your interest there and maybe someone is moving on to a different Lucid (or a different car all together) and would be willing to sell them separately.

You might be able to get some at Discount tire but it is unlikely (you could call around). Here is what its website says:

"In some rare circumstances, we at Discount Tire do sell used tires. A few of our stores will offer barely used tires, including Original Equipment (OE) tires that other customers have immediately replaced upon purchasing a new vehicle, as well as like-new tires that other customers decided not to keep. However, we typically don't recommend buying used tires unless absolutely necessary"

I DID IT!
Got my Michelin Aplin Pa4's installed 255/45 - 21's ( i thought they were 245s, EVEN BETTER!) Lucid would not do it...
Not sure why the Tires state they are for 9-10" wheels which is 9 in the front 10 in the back...as far as being staggered. the 19s aren't staggered so we know the car is ok on 4 squared.

They fit and look perfect! Drives fine, no dash lights or complaints from the computers. Went to Town fair tire next door to Lucid where they proceeded to Scratch EVERY WHEEEL!
If only Lucid just did it. Ughhhh...Now I gotta get them all fixed. SMH Will post pictures. Thankfully I have before videos of all 4 wheels because I've had this happen before..

Interesting. What are the load ratings on those?

I tried hard to find tires that would work for my 21” rims, but no dice. I went with a dedicated set of 19” winter wheels and tires from Lucid.

They are 98Y, extra load, just enough. It's only ever me in the car, I cannot seem to find anymore. I had them from my Audi S7 2 years ago. As i said earlier in the posts, I only have this car for 18 months lease...12 months left now...I didn't want to buy a whole set of wheels. for 1 winter.

Its fine total weight capacity is still over spec.

OEM Pirelli tires for the 21" wheels are 99Y front and 103Y rear. 98Y is well below the required load index rating, which is why Lucid wouldn't install the tires. I tried finding tires that could work, but they always fell short.

 

[CWedge411]

You are right on the specs, but do you know what they mean? They are load ratings, how much weight they can carry. 103Y and 99Y is welllllll over the weight of the car at 7,276lbs. I can't imagine loading an Air up to 7200lbs lol. I don't think Lucid service is aware of this either. Lucid INC, use the 103Y and 99Y because that's what available and over the weight capacity they need. So as a good employee they follow what they think is right and try to use the same. Not realizing you can deviate as long as the rating is over the capacity of the actual door sticker. I used to work in a performance shop where we put all types of tires on different things, mainly trucks. But we had to deep dive into specs to make sure we weren't putting anyone at risk. Trucks are a little more difficult because people carry a lot of stuff and tow with them. Cars are a bit easier to figure max load because normally you might have 4-5 adults and that's about it. You can use the door sticker for reference. 98Ys can handle 6,612lbs, more than enough to carry a Lucid with 5 people. And is still rated for 186mph same as factory

 

[CWedge411]

Another thing to note is the 20's are all 4 99ys or just 224Lbs more than the 98Ys, is 224 lbs going to make any difference in the real world? No. Lucid employees should understand this and also understand that 21's are hard to come by and work with the customers.

That depends on if you want another person in your car or not, I guess; that’s about the weight of a human, plus or minus.

 

[CWedge411]

But if its over the max rated capacity of the Lucids cargo capacity then its not even an issue. Cargo includes other humans
