Haha, I think it’s a tire/wheel combo thing. Had same issue with Yokohama Xm/t on method 105’s. Great minds think alike, I came up with small sections of angle iron, not sure why but I thought washers would be too weak. It was still a two man job.
I have a set of podium’s bought back in 2016, love them! Read this yesterday and thought “oh boy, glad I got them when I did, and so sad to see another quality brand sold and watered down”
VERY glad to see you guys involved and making it right!
