2013 Recon 250 ES needs tires

I have a 2013 Recon ES 250 that needs new tires the factory set wore out pretty quickly it has 22-7-11 in the front and 22-10-9 in the rear I am having a very hard time finding any good replacements looking for something durable and fairly aggressive without robbing power. I do not want to change out the factory rims. Thanks for your suggestions.
