My '79 40 currently is running 30x9.5 OR LT tires. But it is seeing more pavement than trail currently. I have them mounted to stock rims. I was given a set of steel wagon wheels which I just had coated. I want to make a second set of tire/rim so I can switch out the wheels. The wagon wheels are 15x8 with 3.75 backspace. What highway tires does anyone recommend for that size but keeping close to the same height as the ones on it now? I do not have a lift. Currently I'm driving the 40 70 miles rt to/from work almost daily. I would appreciate any advice. Thank you
