Default Tire Specs for 20's

Hi guys, need help on what tire size to buy (round side wall)
What is the ideal tire specs for this wheel setup:

+38 front 20x8.5
+45 rear 20x10

Accoding to some guys in CL this wheel setup should be good and only rear fender rolling is needed.

I wanna go for 265/30/r20 but only Toyo tires are available in this specs. I plan to get the Falken FK-452 tire but they come only in 275/30/r20... I'm scared the 275/30 will rub and need more fender rolling/cutting which i try to avoid. What do you guys think? Thanks

275 won't rub with a +45. I had 275/30/20's on a 20x10 +40 rim and it didn't rub at all. It was only when I got +30 offset that it rubbed. At a +45, you may not even need a fender roll.

275/30/20 and 245/30/20 will work fine with those offsets.

I had no mods done to my car and i have similar offsets. The front barely rubs the rubber fender lining during hard cornering but that was expected.

35's in the rear compare to the 30's will look awkward!
