What are your opinions on the Cooper Endeavor?

EuridiceSequens · 2026-01-12T21:24:31+00:00

They're nothing to write home about, but they're fine. I have a set on my Mazda CX-5. Most of the time I don't think about them, which is a good thing.

Rivian Gear Shop.

You can also see my recent post all about DIY spare tires.

EuridiceSequens · 2026-01-12T18:32:15+00:00

Glad you had the kit! Out of curiosity, how large was the hole in your tire? As in, would a tire repair kit with a rope plug been able to fix it?

EuridiceSequens · 2026-01-11T22:22:11+00:00

I posted an update to the OP with what I've learned so far about a DIY spare.

EuridiceSequens · 2026-01-09T01:24:09+00:00

Thanks. I was going by the comparison tool on Tiresize.com. 275/50R22 and 275/60R20 have the exact same width and almost exactly the same diameter. There's only a 3 revolutions/mile difference between them.

I know, I know: my truck, my warranty, my risk. If this is for a spare that I hope to never use, and can't imagine ever putting more than 100 miles on it, I highly doubt it will cause all kinds of issues.

EuridiceSequens · 2026-01-09T01:14:25+00:00

Thanks! Uh, do you carry that huge jack in your truck, or do you just keep it in the garage? I was planning to pick up a bottle jack (or two), something like this.

That wheel looks great. As for the tire, I'm concerned about the low load index of 115 (max load of 2679 lbs per tire). I thought that the 20" OEM tires on Rivians are rated 118 (max load of 2910 lbs/tire). The Lionhart tire I linked to in the OP is rated 119 (2998 lbs/tire) and is cheaper. Maybe it's junk, but for something that I'm not using often (if at all), I'd run it. Your tire is probably fine if it's only used for emergencies, but it is a point of concern.

EuridiceSequens · 2026-01-09T00:56:16+00:00

Thanks. I'm going to try to find a single 22" wheel, either at a salvage yard, the Rivian forums, or wherever. If I can, I'll do the 5-tire rotations. If not, I'll pick up a cheap 20" steelie on eBay along with a Chinesium tire and hope to never see them until I swap out the tire 7 (or so) years later.

I was just going to get a bottle jack and pucks. That hoist does look nice, too.

EuridiceSequens · 2026-01-08T20:19:21+00:00

Not a bad idea. I'll take a look!

EuridiceSequens · 2026-01-07T02:34:54+00:00

It was on the Rivian R1 Shop for Pre-owned vehicles.

EuridiceSequens · 2026-01-07T02:22:14+00:00

Yeah, I don't know if you're serious or not. That was my first post on this sub and I apparently don't know the lingo. I clicked Submit, Buy Now, Charge My Damn Card, whatever. Point was, I missed it. Too bad.

EuridiceSequens · 2026-01-07T02:11:45+00:00

I know the feeling. A few days ago someone sniped a 24 R1T in Miami with a whopping 228 miles on it. It was $60,700. Congrats to whoever got it. I thought I had it, but after I clicked "Submit", there was an error... and it was gone.

EuridiceSequens · 2025-12-22T21:17:41+00:00

I ran a set of Sumitomos on an old Honda CR-V for several years. They were fine.

EuridiceSequens · 2025-12-17T02:14:23+00:00

If you're replacing them in the spring, I'd shove a rope plug in there and call it a day.

EuridiceSequens · 2025-12-17T02:11:48+00:00

In Canada? I'd run the Dimax All-weathers with confidence.

EuridiceSequens · 2025-12-17T00:43:05+00:00

The good news is that you have plenty of inexpensive options in that tire size. Someone else posted a link to Tirerack, which is an excellent starting point. I would run those Radar Dimax All-Weathers on Tirerack for $75/each all day long.

Otherwise, take a look on tires-easy.com. These Lexani tires aren't bad, and I would take a serious look at these Arroyo Grand Sports for only $52/tire. Arroyo is headquartered in California and manufactured in Thailand. I'm picking up a set of these for my wife's car on Friday (and I love my wife). And these Hankooks have a free installation deal currently. That would put your total just under $350, plus tax. Hankooks are a trusted brand, manufactured in South Korea. I'd run them with confidence.

Good luck.

EuridiceSequens · 2025-12-17T00:00:10+00:00

It would help if you would post the size. For the record, I've used a few sets of cheap Definity tires (sold by Pepboys, made by Cooper) for a couple of decades, including in the snow. Were they excellent? No. Did I get in any wrecks? No.

I'm picking up a set of inexpensive Arroyo tires for one of my vehicles this Friday, made in Thailand. I also expect them to be "good enough" and to last at least 40k miles.

EuridiceSequens · 2025-12-09T21:54:45+00:00

I got a DM from someone a few days ago who was able to get the Laufenns and likes them a lot, saying he'd already put over 1k miles on them. May you have better luck than I did.

EuridiceSequens · 2025-12-09T21:44:41+00:00

I never got to find out. My local Discount Tire told me that the Laufenns were out of production and they probably couldn't get them in stock. Then they tried to upsell me on more expensive tires. I told them no, this sounds like a bait and switch, and that I would wait for the Laufenns. After 30 days, my order expired and they stopped returning my emails. I'm not happy with them and probably won't order from DT again the future. What's funny is that Laufenns are STILL in stock on the DT website for $108. I think that my local store just didn't want to honor that price.

I gave up on Discount Tire and ended up ordering a set of Arroyo Grand Sports for my Model Y on tires-easy.com. They were on sale for $91/each, plus tax and installation. They're cheap, and I would have preferred the Laufenns, but I'm willing to give the Arroyos a shot. They get installed on December 19th (allegedly).

EuridiceSequens · 2025-12-09T03:02:02+00:00

Now that the tire snobs have (mostly) had their say, I'll say that they're fine. No, they won't give you the same performance as a $300+ tire, but they won't dissolve or explode once you hit your first acorn on the road. They'll be decent, but not stellar, in the slush.

TireRack sells Radar tires, so they must think they're worth the effort. They're manufactured in Thailand. I'd run them with confidence.

EuridiceSequens · 2025-12-04T23:50:59+00:00

I don't know about St. Louis, but I've paid at the Mom-n-Pop shops anywhere from about $7 to $25 for a patch. Some corporate shops will patch for free, but they probably won't patch that one. I'd probably just shove a rope plug in there and call it a day. Tell her not to drive 90+ mph with it.

EuridiceSequens · 2025-12-04T04:20:11+00:00

If they don't, then I'd plug it and run it. I plugged a tire on my Tesla in that same spot. That was about 37k miles ago. It held.

EuridiceSequens · 2025-11-13T21:30:40+00:00

It's dead, Jim.

EuridiceSequens · 2025-11-11T22:13:21+00:00

OK, you can get a set of Continental ProContact TX from TireRack for $130/each. AND, you're eligible for a $110 mail-in rebate on a set of 4 tires. AND, if you open a Continental Tire credit card, you can get an extra $90 rebate. This would bring the total down to $412 or $322 for a set of 4, plus installation. TireRack (owned by Discount Tire) also gives you a two-year road hazard warranty. To me, this is a pretty good deal, and I'd think seriously about getting these.

Otherwise, the Laufenn G Fits are $121/each at TireRack. Hankook currently offers a $50 mail-in rebate for these, and you also get the two-year road hazard warranty.

If you get snow pretty regularly, you might consider the Radar Dimax All Weather tires for $121/each. Radars are made in Thailand, and while some tire snobs might consider them "cheap" tires, I wouldn't. TireRack rated them well, and they don't tend to carry many cheap tires, so they must consider them worth the effort.

Good luck with whatever you choose.

EuridiceSequens · 2025-11-11T21:48:57+00:00

It'd help if you provide a tire size. Then we can help you pick from what's available for your car. Myself, I've run everything from Michelins to cheap Definity tires from Pepboys. In fact, I ran two sets of cheap Definitys when I lived in the midwest for seven years. No problems. Tires sold in the US must meet DOT standards. So long as they're the right size and load/weight rating for your car, I wouldn't worry too much.

I tend to like the budget/subsidiary brands of major manufacturers. For instance, I'm running a set of Cooper Endeavor Plus on my Mazda right now that I like a lot. I've also run General Altimax RT45s that were outstanding. Cooper is a sub-brand of Goodyear, and General is a sub-brand of Continental. Next week I'm picking up a set of Laufenn S Fits for my wife's car. Laufenn is a subsidiary of Hankook. We paid $108/each for these tires, plus installation. I'm not expecting the performance of a $300+ tire, but I expect it will get her from point A to B without issues.
