Don't understand tires sizes, tell me what I need.

[BIGRED Z]

If I were to buy these,

What size tires would I need? I'd be going with the 17 x9.5 and 18x10.5 sizes. Thanks

Get 295/35's for the back, and 275/35's for the front. The front will be shorter, of course. But, the tire to rim ratio will be equivalent. If you want the front wheels to be closer to the back wheel height, then get 275/40's.

That tells you everything you need to know about tire dimensions.
