Bead won't pop on stock rims
I need some information. I recently took off my stock wheels to repaint them. I had them professionally powder coated black, then sanded and polished the face before having them cleared. They came out beautiful, I ordered some new tires while I was at it and have been having some major issues with mounting.
Without doing enough research I ordered some 215/45/17 Falken Azenis 615K+ tires, I knew the sizing was going to be a bit tight but I went for it because I really wanted to run these tires. Upon having them mounted, the shop was unable to get the bead to pop on the rims. They were able to air them up to (60+PSI) but about an 8" section of the tire would not pop over the bead on the rim. Regretfully I sent them back and decided to order another tire in the factory size.
Fast forward another couple of weeks of my car being down and I received my 205/50/17 Pirelli P Zero Treffeo R tires. I thought for sure being the stock size that these would pop right on, but again after taking them to be mounted the exact same issue occurred. This time about 6 inches of the bead would not pop. They aired them over 100 PSI and tried putting them in the sun and every other method they could and they would not go on. They said the only other thing to try would be to put them on the car and try rolling it a bit to see if the weight would pop them on.
They ended up dismounting the tires and then just to be sure they put on a unidirectional 215/55/17 and it popped the bead like nothing.
Did I by coincidence order two sets of tires that will not fit the stock rims, or do you guys think there is something else going on? Are the stock wheels unable to use directional or run flat style tires? I'm pretty discouraged by the whole thing as my car has been down over 2 months for something I thought would be a week.
I want something pretty aggressive for the street/track as my car sees far less than 10k miles per year and is ~425 wheel. The other option that I am considering is the Toyo R888 but I am concerned to order those for fear of the same issue. Could this be a speed rating/stiff sidewall issue? Any insight is greatly appreciated!
