I do a lot of surf fishing in Jersey. So I drive on the beach a lot. I have GY Duratracs and they're very good in the sand. I air down to about 15 lbs, there's a lot of sugar sand on the beach I go to.
I have a 2.5" OME lift also but I didn't get that for the beach, got that for off roading.
You don't need a lift for the beach.
