you haven't mentioned the offsets of your rims I think. those tires could rub depending on your offsets since the HR springs aren't too low. Also, if it does rub, the brand of tires will depend on whether it rubs a lot or maybe just a tad.
with front 235/35/19 and (8.5 rims) you will have to get a heat gun and push back the rear part of the front fender linner so it wont rub when parking and stuff. a decent rule with 235/35/19 and your HR springs is that low 30's offsets wont rub.
with 265/30/19 you would have to have a really low offset (with a 9.5 rims) to rub, so most likely you wont rub, but IMO the car will look awkward becasue the front tires and rear tires are close in height and you only have springs. id say go with the 265/35/19 on the rear and keep it close to stock specs (one inch taller on the rear)
the only way you could do whatever you want with tires is if you have coilovers, where you can adjust to reduce fender gaps, and etc.
