275x60x22 Would they fit?

[throughitalldude]

I just got a 2026 R1S Dual and the car drives awesome but the wheels take hits like low profile tires are on the car.

I would like to soften that up a tad. So being a truck guy my whole life my first idea is to increase the sidewall height.

I know the the 20" wheels come with 275x65x20s stock. I have also heard of people putting 285x55x22 on the truck. I found Michelin makes the Defender in a 275x60x22 and have always heard great things about that model tire. Question is will the diameter being 35" not fit? The good is the width is the same as stock at 10.8" Wide.

I wanna say I saw someone say they stuffed a 35x11.5 on a R1T before.

What's everyones take?

Many sizes fit if you don’t care about rubbing or only drive in straight lines on smooth roads. 275/65R20 (34.1”) and ET +48mm is about as big as you can run with no rubbing; full turn and all ride heights. 275/55R22 (33.9”) or 295/50R20 (33.6”) probably won’t make enough difference. Change your wheel size if you want more sidewall and cushion. https://tiresize.com/comparison/

And are you driving around in low or lowest height? If yes, it might not be the tires at all but that you are purposely reducing suspension travel and hitting the bump stops.

I got 295/50r22 nitto grapplers. They look great, not sure if I should go back to stock size. It’s much cheaper.

275/65r22

or

275/60r22

I ask since you mentioned both tire sizes one in your title and one on your post. I am one of those that have 35 x 11.5 tires that I occasionally mount to my R1S - I say go for it as long as it’s a 275/60r22!

A 275/65r22 would be a 36” tire and toooooo big for our wheel wells.

Sorry about that title typo yes 275x60x22 to me it was slightly bigger then the stock 20 inch tires that come directly from Rivian and I figured it would fit.

There have been several that have put 35in tires on, many of which claim they've had no rubbing. The main thing would be to avoid lowest and bumpy curves or if you use kneel mode, be sure to give it a little time to adjust before going crazy after jumping in. I'm guessing you're not off-roading either, so really you should be ok. Now, if you were also going to a different offset wheel, that would be an entirely different story.

Yes i have a lock on 275/60/22 michelin defenders. Based on reviews of the defender tire and the larger sidewall to the stock Pirellis, I think this will be a somewhat night and day ride for the better. I am a truck guy and have always lifted and changed my wheels and tires. The more rubber you add between the road and the rim ALWAYS has pushed the ride towards "pillowness" on uneven roads. The small imperfects, potholes and uneven roads at lower speeds is where my wife is going nuts. At highway speeds and over huge bumps or jolting terrain this thing is awesome but those tiny little things you'd think are nothing the R1S really starts to sing via thumps primarily in the rear. I think this tire swap could put all that in the rearview for us.

If you really wanna soften it up, maybe just stick to 275/60R22 and think about a slightly softer tire pressure too. I’ve seen guys throw 35x11.5s on here, but it’s kinda borderline for clearance. Wider than stock is okay, just keep the height in check.

Wider gets you in more trouble with the outer fender lip especially if you alter your wheel’s offset at all. That’s why we (with larger tires who use them) all run 35x11.5 and not the more traditional 35x12.50.

Exactly and these tires are the same exact wide as stock.

You're putting the same amount of rubber between the wheel and the road as the 20" range tires; why not just buy a 20" wheel to keep the OD stock? You can even go larger with 275/65/20. Then you have a speedo/odo that is correct... you can't swap a gear or reflash the speedo to account for diameter changes that aren't stock. It sounds like it's for your wife and she doesn't care about the tires looking more butch by being larger; she just wants it more comfortable.

You also haven't commented your standard ride height; do you let it go to low at speed or do you keep it standard?

The S will ride worse than the T, BTW.

She really likes her 22" sport bright wheels and I said well I can go with a larger tire to keep them and achieve the same outcome of going to the 20's. Ride height settings we've played with and are not privy to any settings. We sometimes ride in auto and let it lower and over times we have set it to standard and kept it at normal ride height. If we do the tie swap as I mentioned we would kinda check all the boxes. Larger sidewall (more cushion) Defender tire (known for smooth/soft/quiet ride) and we get to keep the 22" brights. Only thing we would do is just set the car to standard height setting unless on a long highway road trip.

Simply leave it on Auto and let software do what it was designed to do—optimize/balance between efficiency, comfort and handling. Pretty much the only reason to override it is when you have a specific needs. Like going off pavement and needed extra ground clearance. Or, traversing flooded roads with possibility of submerged obstacles. As mentioned before, and written about by many auto journalists for their publications, heights less than standard reduce range of suspension travel. Coupled with softer air spring pressure, chances of hitting the bump stops increase. That is what produces harsh ride. Even with the stock R22 tires, in all-purpose and normal everyday driving, it is abnormal for ride to be characterized as harsh.

The shorter wheelbase of the R1S can feel a bit less settled over bumps than R1T, especially with Gen 1 hardware. But that's more about forward and aft pitching. Not about harshness over bumps.

275/60R22 is not a factory size and is taller than the tallest factory option—i.e. there isn't a software config that is even close to it. With regards to instrument readings and range estimation, you're heading into uncharted territory.

Its not necessarily a harsh ride. I even mentioned that to my wife. Its very much the audible feedback the car gives over little imperfections on the road. There is a specific noise that is hitting her ears and going straight to her brain and bothering her. I am a rattle freak my self and understand how that can become tiresome over time. The times it happens most is over cracks or slight imperfections in the road and I know the suspension is not being called upon as its too small. Its truly the lower profile tire that makes the sports car thump thump. So thats why i figured a more SUV sized tire like the 275 60 22 will eliminate a good portion of this.

I think you're probably better off just going to a set of 20" wheels and either 275/65R20 or 275/60R20. If the factory styles aren't to your/her liking, forum sponsor Atomic Wheels have many designs and can even do custom designs.

Same size as you have now tires (275/55/22) but as Defenders will soften the ride noticeably, btw. I went from 21s with the stock tires to 22s with the Defenders...and then changed them to sports tires (Toyo Proxies) because I don't want the plush ride. Even going from the 21s to 22s with Defenders it was noticeably a more squishy ride.

So overall it's not that it's a bumpy ride, just that it's making suspension noise that is bothering her? You're hoping softer tires will fix that? I doubt it will.
