However, 10? years ago, 245 was considered really wide front tire, 295 was recently considered a wide front tire, where as mentioned, 315 is current holy grail. Regardless, any structural improvement found thru the testing suggested, should likely show an improvement on any size tire, just some more then others.


seems to be plenty of fast(er) 3500lb cars on way less than 315's...


*thread diversion*

I for one am not sold on wider always equals better. Data points:
- Corvette road racers on hoosiers - faster on some tracks with 275's square vs 315's square (275's faster on high speed tracks).
- Tom - faster on 275's square with a better compound vs 285/315.

My current line of belief:
-tire compound matters most
-tire temperature matters second
-tire size matters last

So sure, wider is better, but only if you get the first 2 right.

I also think R compound tires may 'buck the trend' a bit past a certain point. Whereas 200tw tires hold the rule a bit better.
