Chain lube or oil on tyres, good idea?

By the same logic, stronger solvents like carb cleaner or MEK could be used as they evaporate quick enough. Solvents are absorbed by the things they attack and take much longer to evaporate out. It takes a good 24 hours for MEK to completely evaporate from ABS slurry where as the same amount will take seconds from an open bottle.

Instead, wipe surface oil off with a dry cloth. Wash the surface with soap and rinse with water. Oil gone and zero damage to rubber. However its unnessasary, any surface oil will be worn off in a couple hundred meters of normal riding.

Your fear of oil is unnessasary. The important point is that there is not a thick film of oil between a tyre and the road surface. If your sump plug fell out that would be a problem , but chain fling is not.

First of all Carb cleaner does not evaporate quickly enough, otherwise it would be brake cleaner. Carb cleaner needs time to sit and dissolve the varnish and other fuel residues. Using carb cleaner on your tyres would be an enormous mistake.

Secondly, I won't be lectured on how to remove oil from a tyre by a man who happily lets his tyres sit with oil or lube on the surface.

And yet, brake cleaner is a hydrocarbon product
Carb cleaner and brake cleaner are very similar, depending on brand and mix. They evaporate at a similar rate. If you are cleaning jets you need to put them in a sealed pot to soak to be effective. Both are likely to contain acetone and xylene, neither of which do I want on my tyres.

Also worth noting this on the wikipedia page for brake cleaner.

"Rubber and some types of plastics are decomposed by brake cleaners by removing binding components. This has the consequence that the rubber will appear unchanged at first; however, it will become brittle, and after a few weeks to months cracks and fractures appear. "

I have not changed my stance. I do not deliberately bathe my tyres in oil, but if I find oil has been spilt I would have no problem riding the bike until they are clean. I have suggested how somone could safely remove the oil, if they were fussy about it.

Fork oil or other oils will be wiped off with a dry cloth.

Interesting. Why do you regard engine oil as acceptable on a tyre but not "other oils"? What's the difference?

[kramdra]

Experience. Were this thread about fork oil, my answer would have been "Fuck no!!! Get it off ASAP!!!", but not with solvents. Front sliding around like Marquez and rear spinning up was not uncommon when I had badly leaking forks, for a few weeks last winter. Cleaning the fork seals would normally fix the leak, atleast temporarily, and no more problems. I am hopeful that my new genuine seals will never leak.

Engine oil, which I use every day, has not caused any issues.

Yet using brake cleaner on tyres is unnessasary, and known to cause damage to rubber, you still use it. Your reasoning that it evaporates before it does any damage is very flawed, and worth noting that vapour will also do damage, it does not need to be liquid, and yes those vapours will stay in the porus structure if the rubber surface. That is far worse than a bit of oil.

You mention microns but clearly you do not know how small they are. The porus surface of a tyre likely has a roughness of 100 microns deep or more, all of which that is in contact with it will be affected. Some will be absorbed quite a bit deeper and I would suggest upto 2000 microns with 60 seconds of contact. That is 2mm, if you were confused.

I was not asked for evidence, I was asked my opinion of why I consider engine oil ok and the other is not, for which my experience that forms my opinion is perfectly valid to reply.

You are a failure.

LHS of rear gets hosed in chain lube (90w gear oil). Once a week(ish) I use brake cleaner to remove it.

Can't say I've noticed a problem. But am not a fast rider.

One thing I would say, is once the tyre is cleaned with brake cleaner, that edge becomes high friction to touch. Wiping a clothe round and the clothe keeps getting stuck / snagged. Doesn't happen on the other side.

Not saying it improves grip, or alters the tyre. I'm sure after a few corners its business as usual.

Marje, you've been sucked into an argument with an idiot with delusions of competence. Just walk away.

He's like a trump supporter. It's obvious he's wrong, the evidence all points at it, but in his mind winning the argument is more important than being right.

I always found an old towel sufficient for wiping off chain oil fling, YMMV.
For road use, I found that a bit of oil on the rubber is nothing compared to hitting diesel, a fuck off great puddle, gravel or freshly 'dressed' tarmac surfaces.
That said, I well remember the days of flung-dung Chinese rubber when the offered traction was probably comparable to a modern day tyre soaked in an oil bath!!

I'm honestly confused by all this. I almost always end up with a bits of oil on my rear tyre after I clean with paraffin, wipe/spin (on paddock stand, all the way to 6th gear and 10k rpm, must be about 120mph equivalent or whatever - yes, I know it's not safe) and then oil with 80w-90 (toothbrush, just gentle layer against rust, nothing more) and wipe excess again. It's like tiny streaks, should I get it off the tyre every time? Paraffin+rag? Is paraffin safe on tyre? Washing up liquid does the job on the rim well, so...
