I have absolutely no idea what truck tire would cost, RV tires are bad enough!
I do know that my 2006 Vette had 80,000 km on it when I traded it in and the front tires looked almost like new.
Now the back tires.....................
My left foot always seemed to slip off of that darned petal!
I just did a quick check on 19 inch Goodyear run flats to fit a Vette and in Canadian pesos they want $297.00 each mounted etc.
Should have kept the car as the prices have come WAY down.
