Bleeding Paselas
Sorry for the click-baity sounding title, but it's actually a fitting description.
As some of you might remember, I recently decided to try some wider (700 x 35) tires on my wet weather bike, and they have been great. The only small issue (and it's not a functional issue, so nothing serious), is that the dye from the treads seems to be bleeding down onto the sidewalls (see pics).
Has anyone else experienced this? I think it was raining the very first time I used the tires, so that might be part of it, and I also noticed that the perimeter of the black dye/paint is slightly uneven in spots (noticeable when the wheels are spinning in the stand). Are these hand painted?

Looks like grease/grime on the rim is spreading outward, not the other way around. Centripetal force and all.

Yes. I have a set of those on my SU100 and they do this. Rim yuck spreads outward over the gumwalls.

incazzare.
Yeah, I agree with the others, it's rim grime spreading outwards, not the treads bleeding color. It's pretty common on tan sidewalls in general. I just scrub them occasionally, when it starts to bug me. It happens the most after riding in the rain, so if this is your wet weather bike, you are going to see this pretty constantly.

Hand-built wheels and not machine-built will solve the OP's problems (assuming the proper wheel builder.)

I'd try taking the tire off the wheel, cleaning the wheel thoroughly, and remounting.
I bet the problem goes away.

Yeah, the wheel building method has nothing to do with it. Thanks though.

Brake dust. You can clean it off, but it'll be back the next time you ride your bike. Not much you can do about it.

But how would it get on the inside of the rim near the spokes? The outward force of the spinning wheel should push anything from the brakes out towards the tire.

That was my first though, but I cleaned the rims/spokes pretty throughly before I mounted them. That said, I could have ridden through something nasty that first day. The streaks were just so dark, that it reminded me of someone crying in mascara.

To avoid this:
- use disk brakes
- only ride in dry clean conditions
- clean your wheel often.
Its pretty much a fact of life on a rim brake commuter.
That wheel builder comment was kinda funny though. ;-)

Embrace it, or you will go insane.

Upgrade your bike to disc brakes! Use a proper wheel builder! Use normal tires like the rest of us!

I agree it looks like rubber grime from the brakes. You get the same looking grime if you wet your fingers and run them along your rubber windshield wipers on your car.
But how would it get on the inside of the rim near the spokes? The outward force of the spinning wheel should push anything from the brakes out towards the tire.

I have brake dust e'erywhere.

I have tanwalls on some of my other bikes, but those are of course "dry weather" bikes so I hadn't experienced the phenomenon yet. Previously this wet weather bike had simple, boring black tires.
I live in an apartment. Any sort of thorough washing involves the bathtub and an earful from the girlfriend. That said, I've been thinking of sneaking in a quick wash at the local car rental place, that generally has a hose just sitting there unattended.

I like tan-wall tires, but only put them on my bikes that will rarely see rain. They still get dirty, but some soap and scrubbing helps. Regardless, I still hate all of that wet rim muck. On my all weather commuter I have drum brakes so no issue.

Search for the Lon Haldeman youtube video on how to clean a bike. Bucket, hot water, Dawn, and one specific brush (that really makes a difference as it really doesn't capture and hold chain grease and road grime) -- you can, or could, order the brush from Home Depot.
The kicker is this regime will clean dirt off your bike, but won't really do too much with tan sidewall tires. Wash early and often, and maybe your tires won't get as grimy. Unfortunately, I don't know of anything that'll clean the grime off the sidewalls once they've started collecting it.

Your sidewalls look really good compared to mine which are black which no amount of scrubbing can completely remove.
