Technical Tire size for a 1946 Buick

Hello. I have been searching around finding the correct tire size to match my 1946 buick.
The rims and tires are 6,5x15 with 8.20x15 tires.

I need new tires so I thought you could help me out.
The car will be lowered by 3" front and back. Will a G78x15 coker with a 31/4 WW (7.10 wich was original) suit the car or will the tire be to small ?
I have been looking through posts and build ups but cant find the tires sizes.

Call Coker or get a copy of their catalogue. There is a conversion table in it.

 

Which series Buick ?
A Special would look fine with 7.10s, a Super should run a 7.60, 8.20s on the Roadmaster .

 

^^^^^^^ I agree,........the big body Buick you have pictured in your other thread needs bigger than 7.10 tires. 7.60 would be the minimum I would recommend.

Thanks a lot for youre recomendations and help.
I found a picture of a 50 Merc with G78 wich looks good but the Roadmaster has more mass on body

 

Its A Roadmaster Model. So 8.20 would be a L78 then acording to the conversion table.
Is there a difference in ride between a 8.00 and a G Version (for example) of radials or is it a look of the the sidewall?

 

Sorry, Diagonal not radial

 

I'm running 225's on the back and 215's on the front of my 49 Buick Super from Diamond Back on stock rims.

 

Every '40s & '50s car or truck I've used on the road has handled better with radials than bias. The "trad" appearance means more to some than anything ...
