16" rim /Max tire size
 

I have just purchased a 91 C2 Cab with the stock cup 92 16" rims on it. the car is needing new tires and I would like to put something a little more beefy on the car. Tire-rack says a 245/45/16 will fit the 8" rims on the rear. but I want to make sure they will fit on the car without any mods.

Also I have seen many post about needing to modify the front steering stops if you are putting 225 on the front. what is the Max size that will fit on the front stock rim that would not require any mods to the car?

thanks for your help to a newbee
