    Slightly larger tyres on 2003 beetle/golf

    Hi,would anyone know if 225/55/16 or 225/50/16 (same rolling circumference) tyres would fit, replacing existing 205/55/16. Depth seems ok and the slightly larger rolling circumference would actually make the speedo more accurate, it's the width that is a concern as not a huge amount of space between the tyre and shock mounting. In theory it looks as if it will work bit I'd rather confirm first from someone who has fitted slightly wider tyres. I see that 225/45/17 do fit but I guess this would depend on what offset the alloys had.

    Many thanks for guidance

    A 225/50 16 has a RR of approx 1904mm which is almost the same as the 1905mm of a 205/55 16 but a 225/55 16 is 1972mm. It is very popular and reliable to fit 225/45 17's or 225/40 18's which I have on my Octavia which is basically the same thing BUT 225 section tyres in theory require a steering gear with reduced lock which my Octavia was factory fitted with as the purchaser specified 225/45 17 as a factory option. In practice it rarely causes a problem, the only downside is the 18's can get quite heavy and overwhelm the OE dampers making the car feel heavy footed and there is a very noticeable reduction in ride comfort.

    225/55R16 tyres will raise your gearing by about 3.5% compared to 205/55R16 tyres. Increasing your gearing by more than 1.5% to 2% is generally considered too much. 205/55R16 is a much cheaper size than both 225/50R16 and 225/55R16 sizes. mytyres for example, lists over 800 tyres in the 205/55R16 size, over 300 tyres in the 225/55R16 size, but less than 100 tyres in the 225/50R16 size. So as you can see, 205/55R15 wins on not just price but on availability too.
