I have a Michelin on the rear but I’m not sure of the condition, it has 10mm height on the blocks but the edges have a 3mm radius

 

Is this tyre still ok for a novice?

As long as it holds air it's fine for a novice.

Turn it around.

I bought a year old evo and that's what the po did.

Turn it around.

I did that when I got the bike, now I have the same radius on both sides of the blocks

Simple answer really, if you are happy with the grip you've got, keep it. If not, buy a new one.

If the knobblies are still pliable and you've got grip use it.if there rock hard might be time to change. I ran the old tyres I bought the bike with until I started hitting bigger obs and found I haveas struggling for grip then shelled out for xlites. Shame I sold the bike a month after lol. New tyres again.

Should be able to tell by eye if the edges of the tyre (the tread) are rounded and worn. And as others have said, try squeezing the tread, it should be pliable.

Age is also to take in consideration.

Last bike I found still had Michelin X1 from 1988 mounted. Geez these tires where stiff I left out all air in the rear tire and the tire still performed as I would have filled at least 1 bar. Very random grip, it got a bit better after an hour of riding around, I gave the bike to the workshop for getting new tires they will be painful to get off the rim without a machine.

I have read in old posts that a Mich or IRC are the best, but would a new mitas be ok for a novice?

As long as you don't go near any sections it will be fine.

Seriously stick to the main brands and spend a bit more money tyres really do make a big difference and just as much for a beginner as a pro.

Cheap tyres also make the suspension feel odd.

à VEE RUBBER was on the Beta I bought this summer and I did not like the traction so, I bought à Dunlop 803 GP. The Price was reasonable.
