Why do some cars just "eat" tires?

This thread is perfect timing for something I'm dealing with.

Current gen Mustang Mach 1 went through Michelin Pilot Sports in 8,000 miles. 8,000 miles. No burnouts or anything crazy. Front and rears. The front tires had considerable wear on the inside while the outside of the tire seemed ok.

Got it aligned just to verify, and everything was in manufacture spec. Shop said it's just adjusted aggressively from the factory. So, I guess I need to budget new tires every 8,000 miles.
And the crazy thing is that my Corvette had a bad factory alignment but even with that I still got 32k out of my front tires (Michelin Pilot Super Sport). I then went on to get 66,000 miles out of my rear tires! I must be the Tire Whisperer, I also recently got 63k from a set of tires on my Civic (Minerva all weathers) and they still had about 25-30% of the tread left.

66k miles on a Corvette rear tire? :ROFLMAO:

You know it's a Corvette, right? I kid, I kid.

My tires are summer tires and not all seasons. Currently running the Continental Extreme Contact 2.
 
A common complaint of Tesla owners I know at work is short tire life.
I only got 43,000 miles from the OE Michelins on my 2013 Model S then 30,000 more before I gave the car to my sister, who then mounted winter tires and put my old tires on the shelf in her garage for this coming spring!
 
My FWD's seem to feather rear tires, getting worse after 100k on the clock. Now that I think about it, maybe it's from bushings giving out? not sure.

Our CRV just ate a tire after 25k--and getting it aligned at the same time as it got new tires. But I think the kids must be cornering hard--not driving hard, just somehow making hard left hand turns. In a vehicle that just doesn't like that.
 
Sometimes the alignment settings specified by the manufacturer are not conducive to long tread life. Owners of the GR Corolla are finding that out. Many can barely get 20,000 miles out of their tires even when they don’t drive that hard.
My old Mazdaspeed6 had aggressive alignment settings as well as 180 tread wear tires from the factory. I can relate to this statement & wish that thing would have gone 20k on a set of expensive tires.
 
Weight and the factory alignment which delivers the required driving characteristics. Ex. Early 2000's BMW 5-series allegedly had substantial negative camber at the rears and would devour the tires. Obviously HP (aka summer) tires will wear faster than Touring tires.

My wife's SLK230 from the late 1990's would eat rears as well.
I'm lucky to get @24,000 miles out of the max performance summer Contis on my C43. Pay to play...
 
My wife's tires on her 2nd Rav4 last and last. No idea why. We don't rotate them.

Teslas are left lane turtles on the NJ TPK. Keep right except to pass.
 
Way back machine here. The first 10 or so years of Ford Escort/Lynx production were known as the worst tire wearing vehicles ever. To increase oversteer for first time FWD subcompact owners, Ford baked a particular suspension camber into their US market model's struts, at least the rears. Some have thought this was to prevent a "scary" experience for small car newbies. Of which there were many millions. If you knew where to source them, replacing them with German model struts with proper architecture made that go away. That finally changed when they started using the Mazda 323 chassis for Escorts about 1991. It may have only been on the GT models at first.

I had an '82 Escort GT from new and about 15k miles was very tops on tire mileage. Often less. That was with decent Pirelli's, Conti's, Avon's and Michelins. When it became more common knowledge, tire dealers would tell you up front that no mileage warranties would be honored on Ford Escorts.
 
To me it seems like all the heavier unibody minivan and suv like vehicles destroy tires.

My old trucks and suburbans used to have constant sidewall blowouts until I started running tires that were slightly oversized with heavy weight ratings
 
My 88 E-150 with the twin I-beam suspension eats tires, and has done so since day one. I haven't found an alignment shop anywhere that could do a good alignment on it. It steers straight, however wears the front tires on the outside in a saw tooth pattern. Cold bend, truck shop alignments you name it, no one ever got it right. I buy non-directional tires and when the outer edge wears and is still safe I have them remounted from black wall to white wall. A set of tires lasts about 30-35K miles no matter what. I drive it so little now that it really doesn't matter much.
 
Our resident tire engineer has reminded us it’s about what you do in curves - hard acceleration whilst turning or braking whilst turning - a tire in a straight path wears slowly …
 
Many factors affect tires wear, but when I observe how many people drive hard to stops, it convinces me that hard braking is the majority cause of tire wear.
That’s one of the reasons why I get such long tire life from all of my cars, and better fuel economy too. I’m always doing long coasting down to a stop. It’s also why my brakes last so long as well (still on the original brakes in my Corvette at 67,000 miles)
