42,000 miles on a set of Firestone Destination LE2s on my Suburban. Purchased on 6-19-17. They've still got pretty decent tread left on them, too, and wearing evenly. It's the second set of these I've had, and I was equally happy with the first set (got 56,925 miles out of them). I'm planning on rotating them to my truck (only gets driven a few thousand miles a year, so tires on it dry rot before they wear out) soon and putting a new set on the Suburban.

Depends on the vehicle usage. For my truck and wife's daily driver, I generally want to change the tires about every 4-5 years so I get tires that should wear out in that length of time based on our annual mileage.

On my hobby car, I will not run on a tire older than 2 years. I like a tire with all the grip I can get so I run tires with a 200 treadwear rating on the hobby car. Thus I get about 7K-8K miles and only have a bit of tread remaining. When I was tracking and autocrossing, I changed tires annually regardless of treadwear. Tire rubber has a shelf life even when there is plenty of tread remaining. I can actually feel the lack of grip as the tires get older.

I go by tread wear don't know how many miles are on the tires on my vehicles

10k on both trucks and car, but the tires were just replaced this year. The prior truck tires had 35k on them and the were down to the wear bars. The car's front tires had 10k and were past the wear bars. FWD and I hadn't rotated them. The rears looked new, so I only replaced the fronts.

I try to wear them down as far as possible, but replace them before season, winter or rain, if they are close. Trailer tires get replaced every 6 years.

SUV will run 35-40K.
Both cars might get 12-14K on rears and twice that for fronts. Price of not driving a Camry.

I’m a tire whore. I’d rather replace good tires often than drive on bricks that last a long time. Especially in the rain!

Go by wear. I know the current tires have ~15k on them. Drive about 5k/year.

I just changed my Tundra's tires two months ago with the same ones. The Michelin LTX's had over 100,000 on them over 3-years of use, I couldn't believe it but, checking the work order, the math proved it.

Both of the newer vehicles have ~ 30-32K miles on them. Both have two sets of tires (winter and summer). Actually my pickup has 3 sets, the stock tires I removed have about 7K miles on them and are low rolling resistant, highway tires. I keep them as I may choose to put them on if I do a lesser 49 trip. Winter tires just came off both vehicles, and I'll probably get another year or two out of them. I'd venture that each of my normal sets have roughly 15K miles on them.

Most of the time a large trip or specific tire need comes along before the last set is really done. Then I'll keep the tires around until I move...and end up selling them for a good price.

I don't do canada with old tires, and I don't tow with old tires.

I also don't mess around with snow tires, when the studs are worn, we replace the tires regardless of tread depth.

10 to 12K on two year old B F Goodrich KO2s

I used to have a Suzuki Sidekick and traded it in with the original tires at 180,000 miles.

Great tires, horrible car.

I have 5 vehicles on Michelin's and generally replace them well before they need it. None have more than 20,000 miles on them at present.

I go by the seat of the pants method ...if it feels like they have lost any grip at all...off they come.

Nought my 2007 Ranger new with Goodyear Wranglers which have just past 40,000 on them.
Have desperatly needed new tires for the last 20,000 miles. You can spit in front of the thing and it will try to come around on you.
Tread still looks good. They have never been patched or plugged.
I just slow way down when it rains or stay at home.
While its past time for tires i am retired and dont have to rely on it to be anywhere at a set time. Have a Fusion and the Mustang as back up if needed.

My Jeep OEM M/Ts have 44k on them and just measured tread at 50% remaining....9/32 vs spare is 18/32.

While pretty conservative driver I intend to make it to 50k and replace by fall.

Problem is so many 'good choices' . I liked the looks of some of those Coopers & the Falken Wildpeak AT3W, along with others.

Not a mudder/rock climber these days. Still looks like a set is gonna run close to $1k from most.

16 year old daughter had a flat tire today. Nail. She called me but only after she already had the spare tire on. Well the spare tire, while new (it is 11 years old) only had 8psi of air in it.

So I drove out and pumped it up for her and we drove back to her mom's so I could pull the nail and plug the tire.

While looking at the tire which had great tread life left, it looked old. I asked her mom about it and she said the tires are over five years old but only have 39k miles on them (she alternated between two cars before my daughter started driving her older one). I checked all the other tires and they are showing their age. The fronts are at 3/32nd but the rears are at 6/32nds.

So even though the rears have decent tread, I have no faith in them. I'm getting her all new tires tomorrow. Tires are cheap when compared to my daughter's life.

It depends. On my current car, an old 2003 Honda Civic, I only have 5-6k on the tires. They're some cheap tires but I have road hazard which has repaired one time from a roofing nail and replaced another due to a cut in the sidewall from my lawn mower.

I typically go around 60-70k on tires with the exception of when I had a 2003 Corvette Z06. I was only getting around 8k per set of rears on that car. Fun to drive but expensive to maintain.

Just at 90,000 on last set of Michelin Defenders mounted on a Ford Taurus. Admittedly, mostly highway miles. Car had 285,000 miles on it at the time - thought about it - and bought another set of Defenders!

Car is seven years old, 26,000 mi, never changed tires. Plenty of tread left, but I'll probably replace them before winter.

I got 35k out of the OEM Conti Pro on my 12 Outback. The car wandered in the dry, and snow was not their strong suit. Replaced them with LER Michelin Defenders and got 55k, but should have scraped them at 50k. The defender was a much better tire all around, but still not up to what the car was capable of. My current tire is the Michelin Premier A/S. I got very good snow performance with a little less than 50% tread depth, excellent tracking, and a very quiet ride. My only complaint is it's a 40k tire at best. My indie mechanic told me 40k is good on a true AWD system car, so I may be buying another set.
