115 XL vs 116 HL tires in 275/50/22

[like2short]

Ford Lightning Platinum uses 275/50/22 tires and they are 115 XL
The GVWR rating for it is 8550 lbs, basically same as R1S/R1T at 8,532lbs
The Tow rating for the Ford Ligthning in Platinum Trim is 8500lbs, but other trims can go higher.

Based on the above, I would feel comfortable using a 115 XL tire on the R1S, and if towing below 8500 lbs likely ok for the R1T.

To be clear, because vehicle X has a certain tire requirement, vehicle Y can use the same requirement? Reality is the weight distribution in the R1/R2 is different, HP is considerably more (>800 vs <600). For 22” tires, there are options with the preferred 116 load rating, why cut an unnecessary corner?

Valid concerns, but the weight distribution is similar.

FORD is 50/50, r1s 51/49 and r1t 52/48

as regards to more power... that's a "tire stickeyness issue for traction under hard acceleration. The all terrain options from the factory tires won't grip as well as the 22" tires setup for street performance yet both are options for Rivian.

Expect the Michelins used on the new 1000 + hp quad to be better on hard acceleration than anything currently available. And that makes sense to get maximum acceleration and cornering power. The traction control system will manage the car with less sticky tire

now the speed rating does matter but gen 1 is limited to 110 and gen 2 130. An H rated tire is fine to 130 and a T rated is good to 118.

115 XL tires have plenty of weight bearing capacity at over 10,500 for combined for 4 tires for a vehicle with a 8532 gvwr.

bottom line: There should be no concern using a 115 load tire instead of a 116 from a safety standpoint. The tire has enough load capacity. A manufacturer with nearly identical weight and towing capacity is using a 115.

Note however the Chevy Silverado EV has a gvwr over 10,000 lbs and uses a 119/116S E load tire in LT 275/50/22

I just read in another thread that the tire load requirement is based on gross axle weight rating + a 10 percent Margin divided by 2. The Rivian has a 4960 lbs rear axle rating while the Ford is 4900. For the Ford based on this math it needs a 2695lbs load tire but the 115 is slightly lower at 2679lbs.

for the Rivian , need a 2728 lbs load tire and the 116 is 2760lbs.

still, I think the 115 is fine...

The even stronger argument is that Rivian used to install 115 rated tires at the factory.

Are modern Rivian's heavier than the earlier ones? I thought over the years Rivian had lost a bit of weight.

If it is unsafe to mount 115 tires on the lighter, more recently built then surely it must have been unsafe to have 115 tires on the even heavier vehicles that were delivered with 115 tires.

If Rivian thought the 115 tires were unsafe, there would have been a recall. If the government thought the 115 tires did not meet regulatory requirements there would have been a recall.

There's been no recall and no reports of those tires randomly failing. Neither Rivian nor the government thinks 115 tires were unsafe.

Sure, it's possible the government and rivian are wrong and that those 115 tires should have been recalled. But I think it is foolish for random people on the internet to think they know more about vehicle safety than the people whos job is build or test vehicles.

Edit - is possible that Rivian's 115 tires were stronger than the 115 spec required. I don't think anyone has shown that the current 116 tire is actually any stronger than the original 115. It is possible the only change was the label. If that were the case then it is possible some other 115 tire might not be as strong as Rivian's 115 tire and could be unsafe.

Also even if 115 tires don't meet the threshold for a recall, it doesn't mean that 116 tires are not a better choice. I am currently rolling around on 115s, but when they wear out I suspect I will replace them with 116 (or higher).

115 is still fine. plenty of people in here have it. You just need to find small mom and pop store to install it for you.

Plenty of other threads discussing this.
For 1 simple reason I will not use 115…
Imagine you’re thousands of miles from home and you run over some road debris damaging several tires beyond repair…the local tire place refuses to install 115, your choice is to buy 4 new tires that meet Rivian spec. of 116H, if you had the correct tires then it might have been a $600 problem, but now you have to buy 4 new tires at $1200+, no thanks…
Other than risk, what does using an incorrect tire fitment get you?

several tires ?? There are only 4 on the car. If all 4 are damaged beyond repair on a road trip you need to buy 4 new tires regardless.. So you'd be at the mercy of what tire is stock.

If you are saying 1 gets damaged beyond repair and the tire shop says they won't work on it because they want all 4 at 116, it will be unlikely they even have a 116 tire in stock, but might have a 115 as there are far more options in 115 for the 22" size.

On a road trip the pirelli oe tire will be nearly impossible to get in the 22" size. Outside of Pirelli, Venom Power has a 116 , Nokian has an all season, and a snow tire and that's it. 20" sizes have far more 116 options.

My big concern on an r1s traveling, is not having a full size spare. This can be mitigated by bringing one.

the 115s for 22" adds more choices between

highway tires, all terrains, snows, all season etc. the factory pirelli is only an season tire. You can of course move to LT to add more choices. I expect over time the tire companies will introduce more 116s in 22".

Nokian One H/T is $900 for all 4…

Yep ! That's one I mentioned and potentially a good tire.. Nokian also has a 116 for snow. I was on their website awhile back and they were promising 22s for Rivian. Right now this tire shows up with online retailers but not on the North American Nokian website.

I would not use the Venom Power Tire or these other off brands. What the heck is that brand? Haha. There is an Instagram account stw direct that says venom powe tires are low quality and hard to balance,

. I have not decided which tire I will use at replacement time, but the Nokian is a candidate, the Pirelli is a candidate, the new Michelin Pilot performance is a candidate (but since only used on front of the new quad might still be a 115) as are highway options from continental general and Michelin albeit in 115 among others.

Any issue with these new Nokian’s being XL vs HL with the OEM pirellis? I went ahead and ordered a set I can update with a review after I get them installed.

We look forward to the update. Pirelli is a homolgated tire so there is likely to be something unique for Rivian. The Nokian should be ok though.

Sorry but this place has really just become thread after thread posted just to get a reaction. Another stupid stupid idea on ignore.
