On the rear of my Mk1 Stanton Switchback I've replaced a 2.35 Schwalbe Nobby Nic Pacestar with a Trailstar of the same name and size and it rubs on one of the chainstays now. Initially I thought the dishing was out on the wheel so had that checked and it's fine. I then took the cassette and disc off the wheel and tried it in the frame the "wrong way", it then rubbed on the other chainstay.
Given up on it and put the old tyre back on with a tube (it had a puncture which wouldn't stay up tubeless) and it's dead central.
Anyone had any similar problems?
Is it a maxle or quick release on the back?
Is the old nobby nic an earlier version?
Borked tyre?
If the bead is sitting right (I assume you've checked this, some tyres are right baskets to get to seat when new) and other tyres run straight then busted / warped sidewall on the new one seems the obvious cause.
It's a 12mm bolt thru axle.
I'm pretty sure the tyre is properly seated, it fairly bangs as the pressure goes up.
Tyre was bought in June, think it might be older type as it's not an Addix one.
I had a tyre rub problem on my Slackline and it turned out to be a lose bolt in the replaceable dropout, might be worth a look.
Does it rub all/most of the way round or just in places?
It sits a few mm. over to one side all round though it does have a stronger bias at one point.
As well as having the dishing of the wheel checked the wheel was also given its "200" mile tuning, so is running true.
I'd be putting the tyre on the 'other' way round as a test, to see if the apparent off centre bias swapped sides, before I wrote it off.
Years ago I had some nobby nics that were off centre. It was 100% the tyre, not any sort of misaligned fitting. CRC replaced them.

I guess you didn't make it as far as the first paragraph on the first post then?
He had the wheel dish checked and also turned the wheel round within the frame. No mention of reversing the tyre fitting, which would be a different check to the latter.

Pretty sure he put the wheel in back to front, not reversing the tyre. Else why take off the cassette and disc?
Send it back. I know schwalbles are often not quite straight but anything more than a slight wobble - send it back.
Time to invoke the Edinburgh defence :-).
