I have tried a number of different steering wheels in my cars and have found that with modern wide tires the size of steering that works best and is more comfortable is 360-375 mm (14.25-14.75 inches) and there are a fairly high number of choices in that size that looks great
I have a Grant Challenger in the SR20 car , The foam rim is surprisingly comfortable and it's a nice wheel ,I just find it a bit small at 340mm(13.5") 10mm more would be perfect
This is my Old Nardi 375mm in Mrs Blue , very nice but thin grip
I sold the Nardi and replaced it with this beautiful Momo California 360mm , they make it both in wood and leather
And by far my favourite obviously my custom modified early wheel which was remade with African Mahogany and reduced to 365mm with matching shift knob
