i pay about $10 more per tire for nittos than i did when i had 17s. i now have 18s and they arent to much more for nittos but other tire brands are a lot pricier. you can put a 315 on the tire and theyll look badass but you dont want a 45, youll want a 35 at the most and i think your stuck with a 305/35/18 on the nittos. thats what ill put on mine, and theyll fit that 10 inch wheel perfect
