Now that I have my two new Magnum 500 15 x 8 wheels I am ready for tires. My plan is to go 255 x 60 15 but I have a question. I see there is a 255 x 70 15 which is taller . Will these work, will these give my rear end (car) a little more height? I am not a fan of the normal stance of sitting back in the rear just a bit. Was going to try new lower coil springs up front some time in the future but wondering if the larger tire would help with that? Cannot imagine a clearance problem on the car and I know the speedo will need adjusting but my speed is pretty far out now so that has to be fixed either way.
