I have just recently put a lift on my blazer, it already had 33x12.5x15 tires on it, it has some 15x8 rims too. I wanna upgrade to bigger tires but dont really have the money to regear, so i want ur guys opinions on this please. I have a small block chevy 400 that is pretty stout. i have a th350 tranny that was built to handle about 550 hp, well thats what the guy said who built it, and it has a np208 trans case. it has 3 73 gears. I know i will lose some gas mileage with 35s, but how much power will i lose. I really want 35x12.5 ssr tires, but dont wanna lose much power? Should i upgrade to 35s or keep 33s. Also wheel it about 70-30 ratio to road driving too. Thanks again. Cory.
