As the title says, what tyre width should I be driving on 13 inch wheels with somewhere around 200 horsepowers? I'm talking about semi-slicks, and maby full slicks. Because of the small diameter, there is less contact than with for example 15 inch wheels, so the tyre should be wider I suppose to compensate.
Semi-slicks are available in 185/60, 205/60 which I think is far to high, and 225/45 which are almost 200 Euros per tyre. 185/60 is available from 70 Euros (Nangkang NS-2R), but also available from other brands. But is it wide enough for that much horsepower on such a light car?
A common full slick size being sold second hand on German motorsport sites are 9.0/19.5 sizes in different compounds. Surely this should be wide enough and provide sufficient traction? Or is this overkill, and will it cause unneccessairy drag/friction?
Hope to hear from you guys, and maby get some feedback on what other powerful Polo's are using, preferably with 13 inch wheels ofcourse.
