Front tire wears out before rear

So I have about 7k on Michelin pilot road4trail. Front tire down to wear bars, rear tire still has a few thousand left. I've never worn a front tire first, I do ride in urban environment alot, I have done a good bit of hard breaking, and it's not air pressure I'm religious at checking bi weekly, 38 42. Just kinda suprised. Anyone have similar wear?

You need to update your location dude. Cause 7000kms is disturbingly low.
I usually get a ratio of 2 rears for 1 front. The T31s i have currently run me 3 rears for 1 front.

I don't check my tires, they don't have time to deflate between changes.

I've been using that tire with mostly urban riding and look to be getting better than twice that many miles on the front. (I tend to brake at about a third to half a G when approaching turns that need slowing.) I keep the tires near the factory-recommended pressure, at 33 for the front. I wonder if you are seeing extra wear near the middle of the front tire's width. With the higher pressure you (seem to) report, I expect your front contact patch is narrowed and concentrates stress toward the middle. This is just a reasoned guess at why you are seeing early wear-out.

My PR4 Trail front lasted 13,000 miles and had another 1-2000 miles left. However I was going on a 1500 mile trip so changed it early. The PR4 Trail rear lasted 7500 miles. My PR5 (not trail) rear is lasting better. It has 7500 miles on it now and looks like lasting maybe 2000 miles more.

That's not a lot of mileage for a front. Other members will chime in, but it sounds like an outlier case.

I currently have almost 8k miles on my OEM TW, still lots of life left. I'm going to pull it anyway to put on matching shinko's.

I have a PR4 on the front with 12,000 miles. Changed out the rear at 11,000, now have a Road 5 trail on the rear.

PR4 Trail front and rear went 11k mi with about another thousand left. I changed them because the center was at the wear bar on the front and almost at the center on the rear. The PR5 I am liking a lot more than the 4. The ride is much improved; surer grip and no squirming in all conditions.

Being slow doesn't make a boring bike. I had a R1 which I thought was boring. Boring is a bike that doesn't speak to you. If you like what your bike is saying let it's voice take you to far flung places. - Vertical C

One of the reasons the fronts last longer than the rears is that the front does fewer revolutions per mile. So your results indicates some sort of error. (or you simply never use the rear brake in the city)

You might look to see if the tire is mounted evenly (radially) around the rim.
There is likely a thin raised rib on the tire next to the rim that can give you a visual. Otherwise you can fabricate a makeshift dial indicator and spin the tire to check if it is radially out-of-round.


The other thing to check is how much balance weight did the front require (or any chance the weights fell off?)
