“So far they seem to be a solid tire. Not a great tire and not a poor tire. Just solid. Steering response on them seems tight. Comfort Is okay but could be better (they seem to get more comfortable after driving them a few hundred miles). They seem to do very well in the rain. Haven’t seen snow yet but I’m confident they’ll do more than fine. Made in the USA. For the price I got them for they are excellent ($134 per tire plus free install through Sam’s Club). Sam’s Club still has the best prices for them but not that cheap anymore. I’m overall happy with them but if I had to pay a higher amount for them I probably would have gone with another brand. I have had the RT43’s in the past but don’t remember much about them besides thinking they were overall good tires.”

What real owners are saying

Tire A

Cooper Discoverer SRX

Positive

The Cooper Discoverer SRX is generally viewed as a reliable all-season highway tire, with users noting good past experiences and comparing them favorably or alternatively against competitors like Michelin. While some owners appreciate their performance for regular paved and light road driving, others note their weight impact relative to stock tires or debate their similarities to newer Cooper models.

“Cooper tires similarities Is the discoverer crossrange the new discoverer srx? I’ve had probably 4-5 sets of srx between current and previous cars and they all look exactly like this. Google says they are completely different tires but in terms of looks they are absolutely identical. 🤔”

“New tires.. for 2015 Limited 4WD....Michelin Defender LTX M/S vs Cooper Discoverer SRX I have had the Coopers for a while now but am looking to get a new set of tires. Should I go with them again or try out the Michelins? The Michelins seem to get good reviews and they're about the same price across both brands. What do you think? Mostly highway driving btw Read more”

“Tire recommendations that are lighter than Wildpeaks BLUF: Looking for an off-road capable tire (225/65R17) that doesn't weigh as much as a Falken Wildpeak. I'm aware off-road tires weigh more by design -- beefy treads, blocks, and sidewalls come at a cost weight-wise. That much I understand. That said, Falken Wildpeaks (30 lbs), Geolandar A/T G015s (30.3 lbs), Toyo Open Country A/T III (32 lbs) and even something more mild like a Cooper Discoverer SRX (31 lbs) represent a nearly 25% increase in rotational mass (I think that is the correct term) over the stock Dueler H/P Sport AS tires, and therefore will drag down MPGs and wear on the drivetrain a bit more over time. Is anyone aware of AT or AT-style tires that are fairly close to the OEM tire weight? Did anyone else shopping for tires take weight into account? I'm not in need of something super aggressive, but I do like to take on mild to moderate trails at the local OHV park, as well as the occasional dirt road overloading trip. The Pirelli Scorpion All Terrain Plus is at least under 30 at 29 lbs, as is the 28 lbs Cooper Discoverer EnduraMax which integrates "all-terrain tire technology" according to the TireRack page. And the Firestone Destination LE 2 only weighs 24 lbs, and the LE 3 is 23 lbs. but I'm not sure how off-road capable those tires are. Thank you, this has been my Ted Talk. Read more”

Tire B

General AltiMAX RT43

Positive

The General Altimax RT43 is widely praised by the community as an exceptional value-for-money all-season touring tire, often compared favorably to more expensive premium brands like Michelin. Users frequently highlight its strong wet-weather performance, solid tread life, and affordability, though some note it can become slightly noisier as it wears down.

“I put RT43s on my Jetta a couple of months ago, and have been pleasantly surprised with how good they are. Definitely recommend them.”

“General Altimax RT43 H-speed or T-speed? I'm about to replace tires and the reviews for the RT43 are great but I can't decide on T or H speed for my 2012 Outback 3.6R. H speed are about $15 more per tire, and the warranty is 65K. T speed (which the OEM tires had) is cheaper and warranty is 75k. I'm in northern california and most of my driving is dry road, some wet, and probably a few dozen miles of snow at most. I just want a reliable decently priced tire - is the increase from T to H noticeable on this care? I would say my driving is assertive but not aggressive. I very rarely drive above 80mph. Many thanks for the advice. Read more”

“Replacement tires I have about 25k miles on my original tires (LR AWD, 18” Aeros) and evening though I have rotated then every 6-7000, I am not going to make it past 30k. So, anyone have any recommendations for replacements? Should I go for the standard Michelin’s? Anyone used anything else? For the record, Ian not concerned with the foam and road noise is fine. I’d like something less expensive, longer wearing, or both, without sacrificing much in the way of performance. For my usage, wet weather handling is more important than high performance. I drive it hard occasionally, but I am most concerned with how it performs on day-to-day commute and driving. (70 mile commute, round trip, 3-days/week). Thanks. Edit: thanks for the info everyone. I talked to my local tire guy and he recommended General Altimax RT43s. He also said the sound dampening foam is mostly a gimmick (which is what I suspected). He quoted me $198 (his prices include EVERYTHING). I could get them from Tire Rack for $152 and local install for $30 + 3 (disposal) which would save me a mere $13 per tire. But based on past experience with this tire shop, it is easily worth the extra $13 for convenience and peace of mind if I need flat repair or warranty claims. Related to that, he said the RT43 is a 60k tire but I should only expect 40-50 on my Model 3 and at best a $15 credit per tire. Frankly, I’d be happy with 40k. Probably going to keep the current rubber for another month, then get the Generals.”

How do we compare tires?

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.

Community buzz from Reddit and forums is shown for context only — it never changes the score.
