Re: Hi! I'm new got a question about 20's on the overland
The dealer supplied OEM on/off road tires are not that good.
Its not the 20 inch size, but highway tread that may be the limits on sand.
All the OEMs have near the same size tire itself, smaller rims larger side wall.
Just air them down and on sand that is in relatively good shape, they will be OK.
Some tire dealer will take your OEM 20 inch tires on trade for a AT tire.
