tire wear: 1mm = in miles
The front tire (new had 7mm) has about 2mm of thread left. I want to go on a ride that is 2000 mi r/t. If the tire get about 1000 miles per mm then we should be good.
Right.
Now you say It depends on tire pressure, driving style (slow old man) and hows the been wearing. All is good with in that way.
Then if it rains, It may not be good.
I have a set of new tires. The rear is good.
Planing the ride to SEO from titusville fla.
Need input from the collective.

Re: tire wear: 1mm = in miles
In my experience, tire wear is not linear. I find they go away faster as you approach (and pass) the wear bars.
As they say YMMV.
Do ya feel lucky?

Re: tire wear: 1mm = in miles
Wear is not linear, nor is it the same for different riders, different road surfaces, different twistiness of roads. Your margin of tread depth required depends on what surfaces you may encounter; dry, wet, slightly gravelly, cold, hot. Asking strangers on the internet if your tires are gonna be good enough for a 2000 mile trip is foolish; taking their advice would be foolisher.
You should use your own past experience in these situations to determine what is right for you. If you don't have that experience, err on the safe side with a wide margin. A set of tires, even with today's prices, is far cheaper than replacement of plastic or god forbid, an ER visit.

Re: tire wear: 1mm = in miles
I change my tires out way too early. But I never have had to get a tire mid trip before either. I'm not getting my full money's worth on any of my tires, but my vacation time is limited and I don't have time for preventable things to go sideways.

Re: tire wear: 1mm = in miles
I would throw the new front tire that you have on. I know changing tires is a pain, but honestly it would be much more of an inconvience if you have to miss a day or two of riding waiting on a tire. WORSE yet if you have an unscheduled dismount as a result of not changing. When it comes down to it, you are maybe saving $50 bucks by changing it early. I know 50 bucks is still 50 bucks, but not worth it.

Re: tire wear: 1mm = in miles
I endorse the above statements - tire wear is unique to the right, especially near the end.
The picture below is my reminder - If I leave Michigan, I have new tires on. This is the service bay at Iron Pony in Columbus, on a sunday afternoon 30 minutes before the closed. The graciously fit me in because the rear tire was not going to get us home. That single rear tire change cost me the equivelent of 2 fulls sets if changed in my own garage. Not to mention the pucker factor of tip-toeing 300 miles to get there.

Re: tire wear: 1mm = in miles
I just played this game myself with the tires on my 2013. Michelin Road 6GTs trying to eke out as much as I could from them mostly just commuting for work. I can attest that the wear accelerates quickly once the wear bars hit.
Better safe than sorry.

Re: tire wear: 1mm = in miles
I'll just add that on multi state trips, all moto related problems manifest themselves late on Saturday afternoon. Typically a few minutes after the dealerships have closed (and are closed Mondays of course).

Re: tire wear: 1mm = in miles
Tire diameter technically decreases as they wear, requiring the tire to rotate more often per mile. Maybe that's why they wear faster toward the end.

Re: tire wear: 1mm = in miles
Lowered wear belt thickness, lowered mass to dissipate heat, higher belt heat, softer wear belt rubber, faster wear rate. Harder to plug a thin wear belt. Trust me. Ref: Ramble 2013. Roadrunner and 0face and Extrememarine will testify.Reserector wrote: ↑Fri Apr 11, 2025 5:48 pm Tire diameter technically decreases as they wear, requiring the tire to rotate more often per mile.
