The stock steering wheel is 15 inches. Are you looking for a bigger steering wheel? Why?
Do you have a standard column?
If you have manual steering and it's hard to turn, you can adjust your caster more negative to make steering easier.

I email XXXXX@XXXXXX.XXX dosent exist. what did you mean adjust steering caster? Wheel aliment? This is a 15 ' wheel.
Yes, caster adjustment is part of alignment. Caster does not effect tire wear but does affect how the car handles down the road. The more positive caster you have, the more tendency to make the car go straight down the road. However this will make it harder to turn your steering wheel and more effort is required. Cars with manual steering are specified with negative caster to make steering easier. However if you go too far negative, this has a tendency to make the car wander. A good setting would be 1 degree negative caster for a car with manual steering. Cars with power steering usually are set 2.5 degrees positive caster since steering effort is assisted. Personally I set my vehicle as far positive caster as I can and don't mind the extra effort it takes to steer but you can set it to whatever you are comfortable with. Camber and toe are the important tire wearing angles and should be set at minimum specifications when using radial tires. You can custom align to your vehicle to the way you want your car to handle.
