Anyone know the tire tread depth when it’s new. Just did 5000 miles maintenance, was told the current tread depth is 8. If the new ones are 11 or 10, the wear out is too fast.
Worth noting, those numbers are (likely) 32'ths of an inch*. Typical new tires are 10/32". There's a few exceptions: Michelin Premier A/S for example, start out at 8.5/32". Get yourself a tread depth gauge; they're cheap as dirt, dispel the mystery. * Tread depth is also noted in mm's sometimes, but anywhere in North America it's typically 32'ths.
Not sure but the Toyo’s that came with our Prime are 300 tread wear so I don’t expect them to last long. Then I’ll put Bridgestone turanza serenities on it and get 100k miles or more out of a set.
And...checking the tread depth on both shoulders and in the center will show whether you have even tread wear. If one shoulder wears more than the other, it's an alignment problem.* If the shoulders wear more than the center, you've been running low inflation pressure (which can cause excessive heat and a tire failure). If the center wears more than the shoulders, you're running high inflation pressure (which some folks like and are willing to accept the uneven wear.) It's somewhat personal choice how much wear is the acceptable max. 2/32nds of an inch tread depth is the summer legal minimum tread in most (all?) states. 4/32" when winter traction tires are required, at least in this state. These are too thin for me. There is no inflection point where tire tread channels deep highway water at one tread depth then hydroplanes as soon as it reaches a lesser tread depth. It's progressive. 4/32" is my personal minimum acceptable tread depth. *And, my old Volvo FWD 850 always wore the outside shoulders of the tread first. It was just the nature of the beast; it understeered a lot. Stiffer anti-roll bars and aftermarket front camber adjusters fixed things.
What OEM tire is it? If it is Dunlop Enasave 01 A/S, the tread when new is only 8/32. My OEM Dunlop Enasave 01 A/S with 20K miles has 5/32 left. Theoretically, at this rate, I can go another 20K down to the legal limit of 2/32, but I will likely to buy a new set after this summer at around 30K miles.
I was always told if you can see all of Lincoln’s head on a penny when measuring the depth, it’s time for new tires. Anyone know what depth that is?
The 300 wear value is only good for comparison of tires within the same brand. Regulations require the manufacturer posts it, but it doesn't set a standard test to use.
Yeah, I know the problems with UTQG rating. But it gives me a good estimation of what to expect from the tires. All of the tires I have had experiences with gave me at most 100 treads wear value = 10K miles, but never more. https://www.tirerack.com/tires/tiretech/techpage.jsp?gclid=CjwKCAjwiN_mBRBBEiwA9N-e_hJDAiVDLaMpm49YROSrov-1PK2Xm0qLcDF3Cc59Eaqrifaw_sKnNRoCmRoQAvD_BwE&techid=48&ef_id=CjwKCAjwiN_mBRBBEiwA9N-e_hJDAiVDLaMpm49YROSrov-1PK2Xm0qLcDF3Cc59Eaqrifaw_sKnNRoCmRoQAvD_BwE:G:s&s_kwcid=AL!3756!3!254641198992!e!!g!!utqg
The rate of tread wear has many factors. One seldom recognized is the abrasiveness of the aggregate used to make roads in different regions of the country. Road-making gravel comes from the nearest quarry with suitable material (or the quarry owned by the road commissioner's brother-in-law). More abrasive roads wear tires faster even if the tire has the best rubber compound, correct inflation pressure and alignment, moderate driving habits, etc. Peng, the rate of tread wear isn't linear. Newer, deeper tread wears faster due to squirm. Shallower tread wears more slowly. The rate of tread wear is slower as the tire is used.
That's very true. Our chipseal paving is so abrasive I have never got rated treadwear from tires I have put on my cars.
