Brought some maxxis high roller a couple months ago to replace the continentals and fitted as tubeless. Once fitted the back tyre wobble side to side when you spin the wheel, I thought the rim need re-turning and took it to a mechanic that I know. He said the rim is fine, he took the tyre off and reseated it again and it still wobble so he think is warped. Left it for a few weeks and I have swap the front tyre to the back and vice verse. Now back tyre is fine and front wobble a bit from side to side. Just wonder if is safe to ride?
