the 16 inch rim is limited by load rating and selection. if you went 17 or 17.5 you might find a lo pro. I do know that if you go with lt tires for the higher speed rating a 245/75-16e has about the same ride height as the 235/80-16e. I chose the transforce ht firestones because I was sick of china bombs( 3 blowouts) and as a light truck tire they have a speed rating of 106 mph, all st tires are rated 65 mph max. heres a link to a guy that has a lot of info.
