Damn tire dilema

[Steve1968LS2]

Ack!

I have an ENTIRE week to finish the exterior of my Fairlane.. paint the hood, add spoilers, paint rear panel, install tires/whees, replace vinyl top, etc..

We are shooting it for a cover on the 8th.. lol.. what am I.. Overhaulin?

Anyways, trying to find tires and I just can't find what I want..

Running 17x8 front and 17x9 rear rims. I wanted a taller sidewall but everything is a 40 series for the rear. The one Nitto tire I found with a 50 series rear, but it doesn't have the right size for the front. Would it be wrong to have non-matching tread patterns? I'm thinking yes..

Want:
245/45/17 front
275/50/17 rear

Could go as high as a 255 front and 285 rear and the sidewall has some flex as well, but I can't find anything. Oh, and it would be better to find Nitto or maybe Toyo tires since they advertise.

I should have gotten 18's but I was trying to "keep it real" and not make the 15-inch wheel crowd crazy.. lol.. plus Vintage Wheel works doesn't make these V60s in an 18-inch wheel.

Why can't companies just make what we need..
