Hi guys
I've just had my wheels powdercoated, tyres have very good tread, front went fine, rear tyre the bead of the tyre took some of the powdercoating off. Garage said it was the bead of the tyre as it went across the edge of the rim. They say poor prep, powdercoating guy says it was all prepped OK.
Garage said the the rear tyre had a very stiff sidewall, tyres 4 or 6 years old, thinking about getting new rear, or was it just bad luck.
Thoughts anyone

I'd expect a tyre 6 years old to be stiff too, so not surprised they commented on it.
Tyre companies say up to 10 years for tyres stored correctly. That's out of direct sunlight, steady temps etc etc, not the conditions they get on a bike that's used occasionally.

OK cheers, I'll get a new one ordered, shame really the treads fine .

I'd dig a nail into the tread & see how hard it feels compared to a new tyre before you throw it away. The 14 year old Avons on my Bonnie are like a brick, they're only on there so I can wheel it around if needed. I'd never ride on them.
I will compare them before they fit, they said even after warming they were unusually stiff and this is from a bike shop that's been going for 30 years
2c from down under. If the casing is real stiff (as mentioned by the shop) it can only be caused by the rubber compound changing, there's nothing else that changes, but we know the rubber does. If you fit them & ride on them, chances are they'll feel 'wooden' & stiff even after warming them up by riding a few miles.
You'll also always have that nagging in the back of your mind if they're up to scratch where you need them, like heeled over into some fun twisties, you sure don't want to find out that they had 'gone off' that way.
Ok, maybe it was 4c worth . . . Just replace them with new rubber, if in doubt throw it out, no issue then & peace of mind.

Yup I think I will, don't want to risk a problem, let alone chew the wheel again.
Atleast the fronts ok 👍
Mate, id be getting both , just not worth the risk.
Fronts 2021 so should be OK Shirley ???
Yeah Mate, i thought it was an oldie. Safe as then👍
If it was mine I'd be blaming the powder coating not the tyre. I've had older tyres than that on and off without a drama. Never know older tyres take off powder coating personaly.
I'm definitely putting the blame on the powder guy although the bike shop did say the sidewalls were unusually stiff even after warming and with the low mileage I do they would be even stiffer when the came off to be replaced in the future.
If it were me then I put the blame neither on the tire nor the powder coating. The blame would go straight to the tire shop that I have been using. Very convenient around the corner with competetive pricing. They have managed to scratch the rims every effing time, put a front tire on the wrong way, and man-handeled new brake shoes with a screw driver when I was too lazy to search for the special hex-key and let them do the whole job. Last time the owner assured me that they would take particular care - result were the deepest scratches they managed so far. :jack: :furious:
Finally got a recommendation from the hardley crowd for a decent shop in a neighbor town. If they screw up, I'll invest in the tools to do the job myself.

I used to fit car/lorry tyres for a living and when done properly nothing touches the front of the wheel only the inner bead of the wheel. However when fitting the tyre will touch on the lip, that's unavoidable. There is also another blemish on the rim which they spotted. My xjr had polished rims, maybe I should have gone that route.
There is a gauge to test the rubber, it's called a Durometer and is known as a Shore test for a tyre Shore A, as it is soft.
I use one frequently but not on tyres on my bikes as they don't get very old.
Are they readily available Geoff ?
Where have you been hiding 🫣
Yes they are, just google search Durometer, there's lots avail from about $15 upwards. Digital & Analogue.. You want the A version for rubber hardness testing.
Most of my testing is done in the B range 80-90 duro.
As Col mentioned A range is what needed for tyres as I believe they are about 40-45 duro.
Meter is very easy to use, I have both analogue and digital meters, personally prefer the analogue, however I think you will find the digital is a lot cheaper to buy.
Here are two which would you recommend 🤔
Of coarse I'm going to say analogue, that's a good price. Quality name brands are about £120 or 240AUD.
