Getting my kit delivered in a month or so and am looking at wheel/tire combos. Would like the speedo to accurate and am not planning on doing a tune at the current time. Am thinking of going 225 40 18 front and 245 40 18 rear. What is the best rim size including offset where I won't have any interference issues? I am looking at OZ racing rims that are 18x8 with +48 offset. Will this combo work or are there other suggestions in options?
