Anyone make a 275/75/18 Tire?

Looking for one of the two sizes.
275/75/18
or
275/80/18

Have not seen either.

These are for wife's 2012 JKU Sahara. Don't wanna do spacers, wanna keep Saraha wheels. 275mm is the widest I can put on with rubbin' issues. That's why I'm looking for a 75 or 80 series tire. Found several 275/70/18, but that's not too much larger than the stock 255/70/18.

Front end will have a small spacer lift. (3/4"-1" to level)

Thanks
