Repro “Onza Porc” white tyres

(you never see that white dog poo anymore though, that's weird!?)

I think the white poo was due to the calcium from folks giving their dogs bones.

You don’t see it anymore because either..

A) dogs have become such outrageous snobs they will only eat ethical, hand reared, grass fed, locally sourced meat.

Or

B) we’re wise to the fact that bone shards can cause havoc with their digestive tract

Yes it’s all about the looks with these, I never actually saw any being ridden BITD
weeellll ..... actually in the '90s I was using Porcs up front and Ground Control in the rear as a very grippy combination on wet, slick chalk on the South Downs, and when the white Porcs came out we did use them lots. They worked in the winter on chalk tracks, and not many tyres did then. I indeed made the mistake of having them on the front of a bike on a Alpine trip, and the increased temps made them terrifying. The side paddles simply bend in cornering, and as each bent, it sent you 1cm more off your line. Gulp. They didn't wear out that fast, no more than any other tyre, and they were often heavily discounted in LBS'. The many pairs I had went this way and that during the later 90's and I know at least one part worn went in the trash. It will be in landfill somewhere....

I had a pair of Rip/Rail and really liked them, never saw the white porcs in the lbs
 
I would say that at 990g the tyre is puncture resistant to most objects apart from a bullet. Ride quality is going to be pants.
if they’re like Chinese branded tyres sold on Amazon - and having tested many Chinese made tyres which weight this much or even more (from Amazon) they all puncture easily and only meant for tarmac @Jimmy2021 has been Amazon testing frenzy

No one buying these will be riding them anywhere. Might as well make them from cheese, as long as ‘the look’ is right.

they are just things made by fallible and mortal humans
