so im looking for some tires. this is for a street car, i dont plan on spending 150 bucks a tire. i drive this car as a DD. im buying new wheels. 15X8 all the way around, i wanted 15X10 for the back but i can only find the wheels with a 4" backspace, and thats obviouly not enough. so would some 235X40 and 255X60's on the back be alright?
