what do bigger wheels/tires do to lap times?
I've done some searching for this but maybe haven't been using the right terms, because I haven't found a related thread yet.
I'm looking at going to larger wheels (and therefore tires) on my 993, and wondered what the correlation between size and lap times was - eg for time trials.
Lots of folks want bigger for (at least partly) cosmetic reasons, but what's the practical benefits? If anyone has anecdotal info on the effect of more rubber on the road to road course lap times, I'd love to hear it.
BTW my experience with moving to R compounds knocked off about 2 seconds on a road course where typical lap times ranged between 1:30 and 1:40 for similar cars. So if you changed to R's along with changing tire size, that would factor into the equation.
many thx
