Learnin my A B C 's tire size

got the "A" bodys and "B" body tire sizes figured out.

My Friend in Florida gots "Spring Fever" wants to cruise...
wants me to help get the fresh eng /trans combo fired up
and asked about a gear and larger tires.

Want to take a few tire sizes and rims to test fit.
>> 235 ---- 275 x 60 - 15.

problem> Wants to keep the skirts, so do I...
What say ye,
What style wheel would look nice,
Can't run the hubcaps, > looses them > spinning tires....lol

Thanks
