57 Belair Tire sizes

[wombat769]

I have a 4 door 57 chev and was wondering if anyone knew what the largest size tire/wheel combo I could put on there. I have a set of 15x7 rims that I would like to use but I dont know if that combination of bigger/wider tires will work.

My 3 '57's that I had in the past all came with 14" wheels and about the biggest I could put on them was about 800x14. I don't know about the 15's. My '56 had 15's and I think I went to a 700x15 on it, but that was back in the day when anything over a 7 inch wide tire was considered radical!
