Default 70 GTO New tires and sizes for a convertible

I check my tires they are January of 2000. So its time to get some new tires for my ride.
1. Will 245 fit up front work without rubbing. Thinking of going 245 x 60 all 4 tires.
2. What tire Mickey Thompson sportman S/T, Cooper Cobra G/T,
I have the Firestone firehawk indy 500 tires on there now and just liked the way they handle and look. They stopped making them I think about 9 or 10 years ago. The BFG's never liked the why they handle and they ride to hard and break to easy from the road. Thanks

The first betrayal is what they did to you.
The second betrayal is what you do to yourself.

I have 275’s (17’s) all the way around on my 70 with no issues so I don’t think you will have any issues with 245’s.

I have bought several sets of BFG’s and am very unimpressed. They don’t age well, the white letters turn brown, just overall not happy. I plan on looking into Cooper Cobras for my my next white letter 14/15’s.

245 60's should fit. I ran 255 60's on the front of my 71 for years.

I've had 245/60/14 and 245/60/15 on my 70 GTO convert. No problems with that tire size.
