I always ran Mickey Thompson’s for those applications - they ain’t cheap.

Looking for a set for my Explorer. I can't think of a reason not to get the Coopers that are 30% cheaper than the Pirellis that came on the car.


Unless you do a lot of off-roading, Michelin Defenders. It’s the best on-highway tires on the market IMO and delivers the best value. Excellent wet-road traction, smooth ride, and can go 80K miles easily if you keep them rotated. I have them on my truck and my wife’s car. And when the factory tires on my daughter’s car wear out, I’ll put them in her car too.

What about for ATVs? I have Maxxis Bighorns on my Honda Recon but got some free brand new SunF rear tires for my old 85 250 fourtrax recently given to me and planned to just get the cheaper SunF front tires for it to match.

I always put Toyo mud tires on my truck.

Used to go with run flats from Firestone on our old Camry but now we have a new RAV4 so it still has whatever it came with from the dealer - looks like they are Dunlop. Not sure if that’s good are not.

Always worth it to spend more on things that separate you from the ground. Absolutely not.


I agree with spending more on mattresses, shoes, and tires. A good mattress improves sleep and every aspect of life because of it. Spending more $ on ankle motion control shoes has helped my feet tremendously, and better tires are better for your safety and your car--which are priceless.

I had some General Altimax tires and they were absolute dogshit. Felt like I could easily lose control in the rain, heavy road noise, and bumpy ride.

Just bought some Continental tires and the difference is immense.

Does having a speed rating of up to 169 mph matter to a regular driver who maybe tops out at 85?

No, and those drivers shouldn’t waste money on those tires.

My first car out of college had Z rated tires, where the rating meant they could stand up to 145mph for 24 hours without failing. The rubber in them was so soft that I once had a puncture from the head of a spoon. And they were super expensive, and I couldn’t get road hazard warranties on them.

I see they have a V rated tire now that’s about the same as I had, and the Z rating has been bumped up.

Michelin’s rarely need any warranty but it comes down to you. Do you personally pay up for quality or pay less and replace more often? Not necessarily a wrong answer.

I’ve had Michelin’s go 60k+ miles on a Suburban mostly highway. They were sketchy toward the end but I knew that and drove accordingly.

If you have the money to spend go for the good ones but do your research. With wife type tires I always look for good resistance to hydroplaning.

If you have a sports car never get perelli pzero tires. They are fine when brand new but they quickly harden and have very little traction.

For a lot of people cheap tires are fine. But if your a type that doesn't slow down in the rain...cheap tires might not be wise.

OP, I didn't bother reading the thread. I can tell you as a former auto industry OEM engineer, there is absolutely a difference, and it can be shockingly large. I have measured it on a test track, and digital data acquisition equipment tells no lies, nor does it believe in ol' Baw's tales.

Between tire classes (ie, all-weather vs summer, eco-tires vs all-weather, etc):
Braking distance can vary by 30% or more.
Cornering capability equally as much.

On a hybrid, you can easily cost yourself 10% fuel economy, and sometimes more, going from low rolling resistance to more performance-oriented all weather. However, the latter will significantly out-brake and out-corner the former in almost all cases.

Tire wear effects and aging effects are real. A summer performance tire will lose a large portion of its stickiness as it ages, even if there aren't many miles put on it. That may in fact be even worse. With miles on the tire, as tread depth goes down, so does resistance to hydroplaning and braking capability. Cornering capability initially improves then starts to trail off too on most tires.

WRT to speed rating, a car that comes with speed-rated tires usually does so because that car is capable of something near the speed the tires are rated at. Legit tire stores won't install lower speed-rated tires than were OEM-spec'd for liability reasons. Exceeding the speed rating of a tire can be a very bad thing. Read on.....

Speed rated tires in general have a stiffer carcass to handle the high speeds without going into violent tire standing wave. The tire can distort several inches when this happens. it is frightening to see it happen on a dyno, a young engineer of mine didn't pay attention to speed ratings once and exceeded the speed on the dyno that the tire was capable of while standing in the room with it. His wife had to bring him a change of undies and pants to work. Such events usually result in the total destruction of the tire and will typically take out a fender with it. The stiffer carcass of the speed rated tire is bad for ride, good for cornering, responsiveness, and braking stability.

Vid of a standing wave This guy didn't get to the critical speed, but he got close. When you hit critical speed, almost the entire tire has that wave and the car will bounce violently just before the tire blows apart.

TL:DR - there are two things in life I have always had money for no matter what my circumstances at the time - books to learn from and the best tires for my car.

You drive your family around on tires. I wouldn’t go cheap there.

The Coopers I bought one time sucked - learned my lesson on tires. Michelin on all my vehicles.



I had the opposite experience. I have had Michelin on 2 different vehicles and they wore out fast. I had Coopers often and have never had a bad set.

The thing about Coopers is they can sometimes be a little harder to find.

Costco has deals on tires. I believe theyre Goodyear. I think Sam's does as well.

You can't go wrong with a set of Kumho's!!
They are a South Korean company.

Also, Cooper Tires is a subsidiary of Goodyear.
