The Stovebolt Site Forums The Shop Area General Truck Talk Tire selection advice 65 short step

Hello
1965 chevy short step half ton
Currently running 235/75/15 on the old original white Steele 6 lug rims, like the way it sits.

I have a set of 15x8 6 lug 10 slot Oem rally's from a 73-87 GM pickup
according to "tire rack" database information I received during a call to the order line they say the 235/75 will only fit up to 7" rims and that I will need to use 235/70 for proper fit on an 8" rim.
Could someone elaborate on this protocol?
If the two widths are the same at 235 why shouldn't the 235/75 work on the 15x8 rims ?

I like the way the truck currently sits with the 235/75 tires and would rather not loose the roughly one inch in height on the 235/70 tires.
Did not really want to go lower.

Thanks for the advice

I ran 235/75 tires on 8" rims for a while before I went to wider tires. It worked. It just looked a little funny having that wide a rim and a narrow tread print.
