Flat Tire from sharp Rock. Alternative Tire?

[OffRoad987]

Got a blowout and flat the other day. Ran over a sharp rock at over 30 mph. Are the 20’ pirelli’s easily susceptible to tire puncture and slicing or that’s any tire? Looking at other off road tires. There are others that can handle the load. I understand i might lose some range and gain in cabin noise.

Everyone was safe. Either ran over the rock or swerve into oncoming car.

Waiting for my spare to arrive. So at the time of the puncture, no full size spare. If Rivian does not have enough extra 20’ wheels to sell as spares, they should include the jack and hub extension anyway. Not only did i have to find a tire, i had to find a jack.
That yellow goo that comes with the car is also worthless, unless you have a small hole in the tire.

Most other AT and MT talk about side wall strength. Softer compounds on the tread help for offroad.
Anyone put aftermarket 20’ tires?
I looked at the usual KO2, Wildpeak tires.
I seen some videos of some off road vehicles flying over large gravel without a care in the world. What are they running?

I too was unable to purchase a spare tire/wheel but did decide to buy an extra 22’ Scorpion tire from TireRack and keep it in my spare compartment so that I at least have that on hand and won’t have to wait for shipping when I get a non-repairable flat. There are some decent aftermarket jacks out there that will safely lift this beast and fit inside my spare tire in my bed. I’ve paired that with a lug wrench and fastened them down in the spare well.

It won’t help me drive away from a blow out but will save me some time. I got a nail in my tire and had a hell of a time finding any shop that would even touch my truck. This way, I can at least take my wheel off and bring it to a shop with the replacement tire on hand.

I have a high lift jack on order. Can use the tow hooks in the front with a soft shackle to change the fronts. 12’ hitch extension will be the pickup point in the rear. The droop thats good for offroading makes for a tougher tire change on uneven pavement/rocks/dirt.

As instructed, i was in maximum height and tire change mode.

A 6 inch steel spacer under the bottle jack fixed things.
I found out later that bottle jacks have the ability to swivel the pickup point to raise the height. ?‍

Yeah I was driving through Angeles National Forest yesterday and there were a ton of rocks on the road and few other cars. Realizing I still need my spare gave me a bit of anxiety. I'm probably going to pick up a spare Pirelli to stash in the back until my full spare comes in.

I have a hi lift jack but I haven't mounted it anywhere yet. Wish Rivian had a set of jack mounts already for the cross bars. That would be too easy.

It sure seems like there are a lot of reports of these Rivian Pirellis getting cut sidewalls. Maybe it‘s just coincidence, but I have never been a Pirelli fan. I’m wondering if the truck weight, the larger wheels (less sidewall), combined with the fact that they can’t be air down very low, is contributing to the frequency of failures. Having said that, I realize the failure in question here was not from an off road adventrue.

I am currently running the Falken Wildpeak AT/3W‘s on my FJ and have been pretty pleased with them - good snow traction, decent off road traction, good road manners, with virtually zero road noise, even after 20K+ miles. They also seem to be wearing pretty well. Would not get KO2’s, mostly based on reports, including first hand reports from friends who have had them, that snow traction is not very good. My guess is, based on my experience, the Wildpeak, depending on the load rating, would probably not come with a significant range hit on the Rivian. With a higher load rating comes more tire weight and less range, but they will be tougher.

My tire slice was in between the treads.
No damage to the sidewalls

i been looking at those Wild Peaks. ?

12’ hitch extension will be the pickup point in the rear.

im Interested in ways of using a hi-lift with a rivian. But when it comes to jacking up the rear using a hitch extension won’t that lift both rear wheels? If so, the electric brake only applies to the rear wheels.

The Pirellis are very lightweight tires, and to achieve that weight, there can't be much in the way of reinforcements in the tire to prevent mishaps like most off-road tires have. I highly doubt Pirelli has some magical technology in their tread and sidewall compounds, otherwise we'd see these tires all over the offroading world. They're a compromise for fuel efficiency, nothing more, nothing less.

My god... Buying a spare tire ahead of time even without the spare wheel... This was a revelation of an idea.

Just ordered one.

The ATs that the Rivian comes with are P-metric, meaning they're basically just a street tire with aggressive tread. Most off-roaders will be running an LT rated tire and likely with an E load rating. The E load rating typically means a beefier sidewall and possibly more plies in the tread area as well. As others mentioned, I'm running the Falken Wildpeak AT3W on my 4Runner in an LT E-load. The problem is that LT E tires in the Rivian's size will be around 60 lbs and you'll likely see lower range as a result. I haven't seen anyone mounting LT E tires yet and quantifying what it does to range.

I saw you posted in the Limestone thread and then found this. From your user name it seems like you either off-road often or intend to.

You might already know about the products below and have already dismissed them for your purposes. If so, maybe the info will be useful to someone else. As soon as I get my truck I'll test fit. But it might be a while.

• SafeJack makes very high quality bottle jacks, bottle jack kits with extenders, Hi-lift stabilizer bases, etc. that are really useful and increase safety when using a Hi-Lift. Very high quality products. The Rivian jack stand pucks would have to be tested.

• You might also be interested in something this tool from Jeepneeds.com. I'm not sure it will fit the custom Rivian D-rings, but the tool creates a lock between the tow d-ring and top of the hi-lift.

Most injuries from Hi-Lifts come from either the base or the top slipping. The force and speed of the jack being "spit out" from under the vehicle can be deadly.

Hi Lift Base has been ordered, but thank you. ?
Everyone should have this for safety.
I might even make a wider one on my own out of steel.

That Verticle D ring tool wont work, since the R1T has horizontal tow hooks. I ordered a soft shackle to secure to the tow hooks. Picture below. Its rated in excess of 15k lbs.

 

[zefram47]

OEM Pirelli is E rated. 20 inch
My Discount Tire receipt shows this and a Tire Rack Website shows this.
Current Tire Weight listed is 57 lbs.

That is incorrect. On Tire Rack you'll find two listings for a 275/65R20 Pirelli Scorpion All Terrain Plus. One is the Rivian specific version which is a 116H Standard Load rated tire in Passenger vehicle metric and listed at 48 lbs with 13/32nds tread depth and a rating of 2760 lbs and max of 51 psi. The second is a Light Truck tire with a 126/123S E-load rating of 3750 lbs, max of 80 psi, 15/32nds tread depth, and a listed weight of 57 lbs.

The Rivian spec tire is NOT the same as an LT E load tire.

The D ring tool that I linked actually is used with the D-Ring shackel in the horizontal position. Perhaps this video makes it more clear than the video I linked above. But it still might not work if the width of the Rivian ring is "non-standard".

The only thing I don't like about the soft shackle is the "loose" connection. That is, if I understand it correctly. But there are pros and cons to all this stuff. The soft shackle would be easy on the Rivian ring. But perhaps not on the bumper or front end in some circumstances if I understand the flexible nature of the connection.

Thanks for this idea! I'm also waiting on a spare. Whats the 20in rim offset to look for a cheap aftermarket?

20x9 +35mm offset?
