Tire wear indicating mileage

Post by Dave1 » Sat Jan 28, 2023 3:10 pm

Wondering if there is a general consensus regarding tire wear by mileage?
I have a 26 Tudor that is due for a new set of tires.
These are 21” Universal brand. I do not have a speedometer so the mileage on this set of tires is a geusstimation.
Anybody out there have a similar car with accurate mileage on a set of compatible tires?

Tire wear depends on lots of factors, the three biggest being toe-in, road crown- which affects mostly the right side tires, and an often overlooked thing...tar & chipped roads. Man they'll wear out any tire quick as heck. Especially the white tires. Most people get around 8,000 miles on the tires you're using.

Another thing which can contribute to tire wear is a crooked frame. If your car tends to pull to one side and measuring from one corner of the frame diagonal to the other side differs, or the engine tends to lean to one side and the hood does not fit right you might have a bent frame. This will cause you to have to pull the steering wheel to one side and get some extra wear on the tires.
Parking inside where the sun does not shine on the tires will also cause the tires to last longer. If they get too much sun the sidewalls will rot and crack leading to blown tires.
Anyway, even one brand tire VS another brand will wear different lengths of time. So replace them when they appear excessively cracked, or when the tread is worn down quite thin. Don't worry about exactly how many miles they are driven.

I hear 8000 miles. My car does not pull to one side, nor does it have any frame issues, Lately it is pretty much a daily driver.

Everything affects tire mileage. Back in the day, 10,000 miles was considered very good, and that was on "premium" tires under the best of conditions.

Thanks, I’ll take it that mileage will typically be from 8000 - 10,000 miles.
This helps as the car was restored when the current tires were installed.

I have 7500 miles on universal tires on a 1923 touring.
The rear will go probably to 9,,000 miles. The fronts are very good and I should last at least another 6000 miles. The tires were installed at the same time, in May 2018. I have often wondered if this is typical wear.
I tour on mostly asphalt counrry roads which are fairly flat at about 30 mph.

Some road surfaces are very abrasive. You get good traction and poor tire mileage. Proper inflation to suit the load carried is very important to tire mileage. In the 1950s, most late model Fords and Chevrolets used a 6.70 X 15 bias ply tire. As I recall, 17 to 20,000 miles was considered very good. Most people got less. Bias ply tires scrub the tread, even going straight down an ideal road with the best possible aligment. They will wear faster than a comparable quality belted or belted radial tire. Tires used to squeal in hot weather at stop lights and low speed turns on smooth pavement. I don't notice that happening anymore. Tougher tread compounds and belted radial tires have greatly improved tire mileage.

If you rotate the tires from time to time, it helps to keep the wear more even. This is easy with de-mountable rims or later wire wheels, however with the old non-de-mountable wheels it would be hard to do.

Yes, rotating T wheels is important, as mine were starting to wear I noticed the rear tire had noticeably more wear than the front. At the time I was a bit surprised at the amount of difference, until I considered that the front tires on a T have a pretty easy life, they are not even tasked with any braking forces as this is entirely applied through the rear wheels.

My rear tires wear a lot faster than the front tires. I believe that's normal under most conditions. Tire pressure should be adjusted to suit the actual load. Pressure that is too high will give a harsh ride, hammer the car needlessly, and cause excessive wear in the middle of the tread area. Tire pressure that is too low will spare the car, but it can cause excess wear on the outer tire tread and can cause casing damage such as ply separation. With clincher type tires, pressure that is too low can cause additional serious problems, such as the tire coming off the rim.

Re rotating non demountables it would basically be impossible to do a "real rotation". You'd have to literally swap the tires themselves which would be just plain stupid in my book. Switching them from left to right isn't that much better either, except maybe the front as the RF tire seems to wear on the outside more than the RR does.

?!? I wonder when rotating tires became an advisable maintenance proposition ?
As Tim points out, rotating non-demountables is impractical, even moreso with 30x3s on the front, and 30x3-1/2 on the rear.

No terribly practical, but, the fronts can be turned around to pick up the lesser worn side created by the camber.
I am sure this would have been done in the depression era to get those last miles from tires.
