Re: From Montana to PA... 1978 K10 Suburban

put 235/75/R15s on it to get it on the road until I get larger wheels/tires sorted
I've run those tires on Suburbans since 1990. Just make sure you get LT Load Range C and not passenger car tires. We live off on a horrible gravel/dirt road and our Suburban has yet to wear out a set before ruining one or two or three. But you might do fine if you're mostly on pavement. Heck, millions of people have probably driven Suburbans billions of miles on 235/75R15 tires!

I just suggest going to straight to a 16" wheel (if you can find them) if you're going to spend money on wheels. All the half ton pickups/suburbans after 1988/1992 have 16" wheels (or bigger). It makes a big difference riding on Real Truck Tires in such a heavy vehicle.
