Tires for an MGB

["Gudz, Roman (EM, PTL)" <Roman.Gudz@penske.com>]

I am considering replacing the tires on my 1972 MGB.  
The folks at TireRack are recommending that I go with the Yokohama Avid H4
and switch to 185/70-14.

Anyone have any experience with these tires (good/bad)?

Are there better tires to go with?

Should I switch to 185/70-14 or stay with 175/70-14?

I am using wire wheels.

Thanks, Roman
