Oil on rear tyre

Just phoned perth mcs who have my bike at the moment. They haven't had a proper look at it yet as they are busy, but he said he noticed a lot of oil on the back tyre when taking it in, and the rear tyre may need replaced.
Is this standard practice? He said if it was only a small amount they could just clean it up, but if it's too much, they'd advise replacing it.
The tyre has loads of tread on it, so I'd be dissapointed if I had to replace it so early, but if it saves my life I'll cough up.

From then on, I and the bicycle feelings deeper.

Why is there oil on the tyre? Overoiled chain? Overactive Scottoiler?

Personally I'd clean it up and go for a gentle ride on a dry day.

find out where the oil was coming from in the 1st place. if your bike is a 4 stroke you might have topped up the engine with too much oil & it's coming out of the crankcase breather pipe, may only be coolant leaking from the expansion tank onto the tyre.
i shouldn't imagine you would need to change the tyre, a warm bucket of soapy water & a good brush will sort it out.

No, I posted full details in general bike chat. I hit a wall and my clutch casing smashed. Stopped fairly quickly afterwards facing downhill though so it all went into a gutter on the side of the road. Any oil on the rear tire probably accumulated when being lifted onto the recovery lorry.

sorry muzza i just read the workshop pages, lots of clever guys on here that know their stuff. bike shops love selling you things so if the tyre is good with no cuts or chunks missing from it then why change it? as said, bucket o' soapy water & elbow grease. if you have any doubts about the handling characteristics or you have no confidence in it then buy a new one for peace of mind.

I think the bike shop are obligated to point it out to you, its then your choice. I think it would be negligent for them NOT to point it out and recommend a new one (bike shops are concerned with doing a good job/customer safety - NOT cost (to the customer)).

If it were me, I'd clean it up with hot soapy water ... and just take it easy on it for a bit (if you have just had an off, then that is probably going to be the case anyway?), but its your call!

It depends how long the oil has been on the tyre for.

I've been on tyre courses where they show you the damage substances can do to rubber. One of them is standing a tyre valve in a pot of buffsol. And the valve actually swells up massive. Then when you take it out, It goes back to normal size. But is really squidgy.

Another one we were shown was when people have a Liter of top up oil in their boot with their spare wheel.
The oil has seeped out of the bottle, and onto the tyre.

And it causes the tyre to go out of shape etc.

If its just a one off bit of oil on the tyre, I would personally just wash it off and go easy on it for a bit until its scrubbed in again.

When I was knocked off my NC29, the rear wheel was swimming in engine oil where my engine covers smashed.
I just washed it off and used the tyre again when I rebuilt the bike.
