Has anyone with an early Viper with 13" x 18" rear wheels had trouble finding 345/35/18 tyres?
I have tried various supliers and been told this size is no longer manufactured.
What if anything is available and suitable for our purposes?

Just been told I am running oversize tyres apparently the correct ones are 335/30/R18 I have been using 345/35/R18 can anyone confirm?
