Goodyear or Continental?

[folivier]

I need to replace the 4 rear tires on my '93, 11R24.5 load range H. Here in San Antonio it looks like the best prices are about $520/tire + mounting, disposal, etc.
Goodyear or Continental are the only options I've been able to find so far in San Antonio.
Anyone have anything good or bad about either brand?
Or other options near here?
We're heading west on Hwy. 90 and down to Big Bend when we leave here so I'd rather replace them here than take a chance out of town, may not have any better options until we get to El Paso.
I stopped at a couple truck stops and it's scary when the guy says "I've never done a motorhome before, how do I jack it up?"
I guess the coach has a jacking pad on the frame? I know if you jack it up on the axle it just jams the tire into the wheel cutout. So what's the best place to jack it up to change tires?
Thanks!
