Rules for next year just announced. Limited class cars will have to run Yokohama Advan A052. It may make things really difficult for us but it was a necessary growth step for the series, so I get it. We’ll figure things out.
I don’t expect them to have any decent width 15″ tire through 2020. By the time 2021 rolls around, maybe.
Also, realistically I don’t think we can hope for wider than 245. We can (and have) told them they should go wider, but it’s a different culture and mentality with Japanese brands. We can’t get Enkei to make a 15×9 for crying out loud. They will look to what currently exists and is successful, I don’t think they’ll pioneer a new size.
