My '18 Tahoe LT is getting close to needing some new tires. I am currently at 39,000 miles with the stock Michelin's. Tire Rack has really good reviews on the General Grabber HTS over the Bridgestone Duelers. The General Grabbers are significantly lower in $'S too but the warranty of 65,000 miles on the Generals is much lower than the 80,000 of the Bridgestone's. I am in the Reno area where it can snow, but typically is gone in a day or two. So do you get what you pay for when it comes to tires?
Count me in on the Michelin fan club. I own 4 cars at the moment, plus I have six adult kids and all their cars coming to me for advice. I've bought and used up pretty much every brand of tire over the past 40+ years. I will tell you, I am a cheap bastard, if there's money to be saved, I will save it. But I will never buy anything but Michelins again. They cost a bit more, but wow, they are so worth it. It's the only brand (besides BF Goodrich, which is owned by Michelin) that has earned my loyalty.
Lots of reasons, but the biggest one for me? And don't laugh, but they stay "round" until the end. By that, I mean they keep their integrity, no broken belts or weird high spots, so they roll smoothly without vibration even when you've had them on for years. I can't say that about any other brand. I've had other tires, including major brands like Goodyear and Firestone, feel like you're riding on square wheels after less than a year, and I don't abuse them or hit a lot of potholes or anything. My beef with Bridgestones is that they are ok on dry pavement, but even a light rain and you might as well be driving on ice, just my experience.
Just this past weekend, I was driving back from Tennessee, 85+ mph in my 2001 Yukon XL and I remember thinking, "I can't believe I'm doing these speeds in a 20 year old truck and it rides smooth as glass." Get yourself the Michelin Defenders or the LTX or whatever they call them (I've had both on my truck) and rest easy that you made a good choice. I'm on Defenders for the past 3 years, but my previous set was the Costco tire they're talking about. I had those on for probably 8 or 9 years and used them up. I would have gladly gone back to those but I'm not a member anymore. The Defenders are identical in looks and performance for my purposes - street only, no off-roading. I live in Ohio, so we get all the different weather, they work well in any season. Hope this helps.
