Tires Lifespan
Last edited by berman2921; Mar 1, 2019 at 03:26 PM.
When buying tirs check the mileage warranty and get ones with higher mileage rating if you want them to last longer.
there are drawbacks which is less grip...
tire rack explains all this pretty good.









I have OEM Contis on my 2016, and am not expecting decent mileage from them either. I won't be buying Contis as replacements, either. Replacing OEM Contis (or any OEM tire) with the same tire makes no sense.
Car manufacturers buy tires on contract by the train-load, and always from the lowest bidder. To think they select tires for actual performance is nonsense. So I have learned through the decades not to expect wonders from lowest bidder tires.

There are other sites for other vehicles and ya have to buy Michelins or you are not cool.
I hate low profile tires...wheel damage and limited on what you can get for tires that last long time.

Each tire, beside seller warranty has oficial, molded on the side tread (wear) number
I had 16" tires on older MB lasting me over 50k miles, even all the warranties are stretched, even on Michelins.

if overinflated they will likely wear down the middle--
then they won't last long.
The recommened tire pressures are for a loaded car-
driving around with one person may wear tires down the middle.




I always inflate to chart showing max load + 3 psi, while seldom have more than my wife with me, yet, thanks to my love for hard cornering I always end with tires having good thread on the center and wires showing on the edges.
I run my E350 RWD on stock 18's, Contisport Contact 3's, at 40 psi checked every month or so. Weirdly, my dealer usually has the best price.
So far:
Fronts: 245/40/R18 fitted at 75000 km (46600 miles) and now 50000 km (31000 miles) later still with heaps of life left
Rear: 265/35/R18 fitted at 103000 km (64000 miles) and now 22000km (13500 miles) later and again heaps of life left.
Previous set on the rear fitted at 68000 km (42000 miles) and scrubbed out on the edges at 35000 km (21700 miles) due to a slow leak on one and me not checking the tyre pressure in between services. I also do about 2/3rds of my driving on good highways. I did have a full alignment done at the dealer at 103000 km (64000 miles) so that has helped improve the wear.
I replaced them with Michelin Pilot AS3+ and after 10k miles on them, (again never rotated) they are measuring 8/32" tread.
Interestingly the Contis have a 480 treadwear rating compared with the Eagles with a 400 rating. I will likely replace the Contis with the same tires, for comparison purposes.
I overinflate to the lesser of the max sidewall pressure or the average of max sidewall pressure and the A-pillar sticker. I was getting shoulder wear on the Contis until I overinflated. I am a pretty mild driver and hard cornering is unusual for me, as is wheel spin or hard braking/ESP actuation.

At least for passenger cars, the only Conti worth having is the Sport Contact 6--far, far superior to their previous efforts, and ride especially good in the larger sizes (19/20).





Instead, the tire manufacturers have to certify their tires with the DOT, independent of OEM car specs. If the tire says it's maximum load safe pressure is 50psi, then you can safely inflate to some value less for margin. In the pic below, my tires are cold inflated to 42psi, and the picture shows the pressure after an hour of driving on the interstate, in 93° ambient heat.
The ride quality is not appreciably different than when inflated to 32psi. The tire wear is much more even across the tread, and gas mileage is improved. Do what you want, but I don't subscribe to old wive's tales about tire pressure. And I have no bent wheels.

You're also in Texas, we get lots of potholes up here from the snow so not getting bent wheels doesn't mean anything.
And it's not old wives tales, pretty much every recommendation out there tells you to use the placard on the car, not the pressure on the tire. It's more like you're starting old wives tales.

Carmakers, as most manufacturers, are all about avoiding complaints about subjective attributes, such as ride quality as it relates to tires. Therefore a low-ish pressure is specified by M-B to produce a comfortable ride. Tire longevity and fuel economy both benefit from the highest inflation possible, up to the point of excessive center tread wear.
I measured, very carefully, excessive shoulder wear when the tires were inflated to M-B's recommendation. Since I have overinflated to 45-48psi, tread wear has evened out across the tire. Ride is not noticeably different. Fuel consumption is maybe 0.1mpg better, for sure it is not worse. My goals in operating a vehicle are longevity and fuel efficiency, with adequate ride quality. At this moment, I am achieving these goals.

Actually Costco is supposed to be pretty decent. They tend to pay well so there's not that much turnover so they kinda know what they're doing. I see all sorts of high end cars there. I take mine there too, they tend to have the best price for tires and include road hazard, lifetime balancing and rotation.
They're also good about replacing tires. I've had a few bent/cracked rims and they swap out the rim/tpms sensor for $15.
